Arcadia calibers were highly innovative for their time, and the Fleurier Watch Company was considered one of the international ambassadors of Swiss watchmaking. Sanz’s ultimate plan is to restart production of Arcadia movements in the town of Fleurier , with redesigned and redeveloped calibres that can replace ETA movements. His concept is about simplicity and quality and Sanz considers it important to manufacture Arcadia movements that work well, and to create watches that are reliable and last and that can be passed on through generations. With this in mind, and using modern technology and manufacturing techniques, the Fleurier Watch Company is now well underway with design and prototyping of future calibres.
Another possible advantage was fire control; at long ranges guns were aimed by observing the splashes caused by shells fired in salvoes, and it was difficult to interpret different splashes caused by different calibres of gun. There is still debate as to whether this feature was important.

Gun construction and rifling diagram This was an Elswick Ordnance export design, completely different from and longer (30-calibres, 183.5 inch bore) than the contemporary 26-calibres British naval service 6-inch Mk III, IV and VI guns designed by the Royal Gun Factory, although it fired the same 100-pound projectiles. The gun was of a complex all-steel built-up construction, of a steel A-tube surrounded by multiple steel hoops, breech-piece and jacket. Several were acquired by the British government for coast defence in the UK and were given the designation 6-inch gun Mark V. The breech fittings and firing mechanism were modified in British service to standardize them with the British service guns, Mark IV and VI. The breech-screw was locked by turning to the left, unlike standard service guns made by the Royal Gun Factory, which all locked to the right. Rifling consisted of 28 grooves of the polygroove "Elswick section" type, increasing from 0 to 1 turn in 30 calibres (i.e.

Superb gun-crew training allowed Napoleon to move the weapons at great speed to either bolster a weakening defensive position, or else hammer a potential break in enemy lines. Besides superior training, Napoleon's artillery was also greatly aided by the numerous technical improvements to French cannons by General Jean Baptiste de Gribeauval which made them lighter, faster, and much easier to sight, as well as strengthened the carriages and introduced standard sized calibres. In general, French guns were 4-pounders, 8-pounders, or 12-pounders and howitzers with the lighter calibres being phased out and replaced by 6-pounders later in the Napoleonic Wars. French cannons had brass barrels and their carriages, wheels, and limbers were painted olive-green.

The ship was rearmed with an assortment of guns of various calibres for training purposes, replacing Souverain in this role. Her crew and trainees numbered 1200 officers and enlisted men. Couronne was replaced as a gunnery training ship on 1 December 1908 and disarmed on 1 September 1909. She was subsequently converted to a floating barracks at Toulon until she was scrapped in 1934.
The Nagant revolver remained in service with the State Police, along with a large variety of sidearms of all types and calibres. The Police used also Modèle 1892 revolver and Rast & Gasser M1898 revolvers as well as a number of pistol designs: Mauser M1910, Mauser C96, Beretta M1923, various Browning pistols (wz. 1900, wz. 1910 and wz. 1922), Ortgies Semi-Automatic Pistol, Cebra wz.
The KwK 40 armed many of the German mid-war tank and destroyer designs, replacing the Pak 40 in the latter role. Depending on the source, the Pak 40 may be referred to as the 7.5/L46, referring to the barrel's length in calibres. There were two versions of the KwK 40, which would be referred to as the 7.5/L43 or 7.5/L48.
Disadvantages included the toxicity of the NO2 if leakage occurred, with several instances of crews being poisoned and incapacitated by leaking bombs and the relative fragile nature of the casing which meant that the bombs had none or little penetration on impact, limiting their effectiveness. The Gros Andreau bombs were produced in three calibres: ;: weighing , containing of explosive. ;: weighing , containing of explosive. ;: weighing , containing of explosive.
The Weihrauch HW 45 is an air pistol manufactured by Weihrauch & Weihrauch in Germany and originally developed as a collaboration between American importer Robert Beeman and Weihrauch. It is more commonly known in North America as the Beeman P-1 after the US importers and is a large, full power air pistol with an ambidextrous grip, available in three different calibres: .177, .20 (as a special order) and .22.
The Allied focus returned to Pantelleria in early 1943. The radar installations and airfield on the island were seen as a real threat to the planned invasion of Sicily (codenamed Operation Husky). The Italian garrison on the island was 12,000 strong in well-entrenched pillboxes and 21 gun batteries of a variety of calibres. In addition, there was an opportunity to assess the impact of bombardment upon heavily fortified defences.
German 20 mm anti-aircraft gun The Germans had around 5,000 troops in the immediate area of St Nazaire.Bradham, p. 38 The port was defended by the 280th Naval Artillery Battalion under the command of Kapitän zur See Edo Dieckmann. The battalion was composed of 28 guns of various calibres from 75 mm to 280 mm railway guns,Ford, p. 29 all positioned to guard the coastal approaches.
It had a regulator that could adjust the rate of fire and was chambered in a wide range of calibres and fed from either 20 round overhead magazines or 15/24/30 round feed strip. Hotchkiss M1922 was used with great success by Greek army during Greco-Italian War. It was also used by the Chinese Nationalist Army during the Second Sino-Japanese War to fight against the Japanese Imperial Army.
37,818 shells of all calibres were fired by British artillery and the US Army I Corps artillery, including 155 mm, 8-inch, and 240 mm shells and 325 rockets from a US Rocket Battery. Firing directly upon the enemy, the Centurions of C Squadron, 1st Royal Tank Regiment used 504 20-pdr shells (the tanks also fired 22,500 rounds from their machine guns).WO/308/53 TNA, London.
Gough, who had now received word of his dismissal but who remained in command until formally relieved, advanced against the Sikh army. He had three infantry divisions and a large cavalry force, with 100 guns of various weights and calibres. In spite of his successes, Sher Singh, who commanded the combined Sikh forces, was running out of strategic options. His large army was unable to find enough food.
The Ministry of Defence Production (, abbreviated as MoDP), is a Cabinet-level ministry of Pakistan government concerned with the development and production of the full range of equipment and stores for the Pakistan Armed Forces ranging from platforms such as main battle tanks and multi-role combat aircraft to guided weapons, small arms, uniforms and unguided munitions of all calibres. The current Defense Production Minister of Pakistan is Zubaida Jalal Khan.
Its barrel length of 60' was just 40 calibres, slightly limiting its muzzle velocity. Only three guns were built, but they did not see combat with Furious before they were removed from her and transferred to the s and for coast-bombardment duties. Only 85 rounds were fired in combat operations before the war ended. All three were removed from service in 1920 and served as proving guns for cordite tests.
Tectran AV-UCF fire control vehicle Astros II are normally grouped in artillery batteries consisting on average of about 13 vehicles: 6 of them are Astros II launchers, 6 are rocket resupply trucks and 1 a special radar-equipped vehicle controlling the fire-control system. The launcher is capable of firing rockets of different calibres armed with a range of warheads. Each rocket resupply truck carries up to two complete reloads.
30-06, 6.5×55mm and 7.62mm NATO. Some of these rifles are still in competitive use today although with the benefit of new barrels. Besides conversions of original Karabiner 98k rifles other sporter variants made by a number of manufacturers such as FN Herstal, Zastava, Santa Barbara (Spain) and many others have been available at various times in a wide variety of chamberings, but most are large-bore hunting calibres.
During the night of March 25/26 the Army, in cooperation with 31st Army, stormed the town of Rosenberg and advanced towards Balga, capturing 6,200 soldiers, 25 tanks and 220 guns of various calibres. Immediately after the operation ended on March 29 the 28th was reassigned to the Reserve of the Supreme High command and began moving across eastern Germany towards the Oder River.Soviet General Staff, Prelude to Berlin, pp.
Thomas Thomson, ed, Diurnal of Occurrents (Edinburgh, 1833), pp.232, 234. Attempts were made to supply Grange and the Castle from France and George, Lord Seton, negotiated for support with Duke of Alba in the Spanish Netherlands. In July 1571, John Chisholm, controller of the royal artillery, was captured after setting out from Dieppe with money from the exiled Bishop of Glasgow, cannonballs of four different calibres, and pikes.
Mountain artillery, which includes pack howitzers, mountain howitzers and mountain guns, is designed to accompany mountain infantry forces. Usually lightweight and designed to be broken down to be portable by pack animals or even soldiers, they often are in limited calibres with low muzzle energy. Correspondingly, range and anti-armor capabilities are limited. However, they can deliver useful firepower in locations that may be inaccessible to heavier support forces.
The Vickers design, very similar to their 6-inch howitzer, was approved in August 1915 and first substantial order placed in March 1916 for 50 howitzers, with 30 more in the autumn. It was 4–5 tonnes lighter than the improvised 8-inch "howitzers" Mks I – V. The Mk VI barrel was of built-up construction and was 14.7 calibres (117.7 inches) long, with a range of 10,745 yards (9,825 m).
With a barrel length of 50 calibres, it would have had about twice the muzzle energy of the US 75mm gun. However, the final gun turned out to be too big to fit into the tank that it had been expected to fit.An Alternative 1930s British Tank Gun - And Its Successor Anthony G Williams It was noticed that the US 75mm cartridge was almost the same diameter as the British 6 pounder case.
In many of his reported cases, Holmes frequently complains of the way the crime scene has been contaminated by others, especially by the police, emphasising the critical importance of maintaining its integrity, a now well-known feature of crime scene examination. He used analytical chemistry for blood residue analysis as well as toxicology examination and determination for poisons. He used ballistics by measuring bullet calibres and matching them with a suspected murder weapon.
Blackmore, H L, (1976). The Armouries of the Tower of London: The Ordnance, (HMSO, London), p91 The gun was bored out to 10.5 inches and a new built-up wrought iron inner tube with inner diameter of 6.29 inches was inserted and fastened in place. The gun was then rifled with 3 grooves, with a uniform twist of 1 turn in 40 calibres (i.e. 1 turn in 252 inches), and proof fired.
The rapid manoeuvre warfare practiced in the North African Campaign led to a requirement for a self-propelled artillery vehicle. This could relocate faster with the flow of battle, compared with traditional field guns. The principle of portee, carrying anti-tank guns on the back of trucks was limited to smaller calibres. The first armoured vehicles were brought into action at the battle of El Alamein and development continued throughout the war.
The watch movements are purchased from well-known Russian and Swiss producers with the basic calibres by Dubois Depraz, Concepto, Soprod and ETA. The movements are refined and hand engraved at the manufactory of “Alexander Shorokhoff“. The screws are also blued here; the dials and cases are covered by enamel. The production of own manufactory movements is planned; at the moment the manufacturer is already making its special modules for the regulators and chrono-regulators.
Even worse, it was discovered that the Cromwell did not have a turret ring wide enough to take the new High Velocity 75mm gun (50 calibres long), so it would have to be armed with the general purpose Ordnance QF 75 mm. This left the Firefly as the only tank available with firepower superior to the QF 75 mm gun in the British Army's arsenal, earning it the "highest priority" from Winston Churchill.
The Madsen is a light machine gun that Julius A. Rasmussen and Theodor Schoubue designed and proposed for adoption by Colonel Vilhelm Herman Oluf Madsen, the Danish Minister of War, and that the Danish Army adopted in 1902. It was the world's first true light machine gun produced in quantity and Madsen was able to sell it in 12 calibres to over 34 countries. The gun saw extensive combat for over 100 years.Kokalis, Peter.
Maximum projectile velocity obtainable with gunpowder in cast cannon was approximately . Increased projectile weight through increased caliber was the only method of improving armor penetration with this velocity limitation. Some ironclads carried extremely heavy, slow-firing guns of calibres up to . These guns were the only weapons capable of piercing the ever-thicker iron armour on the later ironclads, but required steam powered machinery to assist loading cannonballs too heavy for men to lift.
Cuniberti's "ideal battleship" Cuniberti is best known for an article he wrote for Jane's Fighting Ships in 1903, advocating a concept known as the "all-big-gun" fighting ship.Cuniberti, Vittorio, "An Ideal Battleship for the British Fleet", All The World’s Fighting Ships, 1903, pp. 407-409. Up till then, the navies of the world built ships with a mixture of large and medium calibre guns. There was constant experimentation with calibres and layout.
Sportco was an Australian manufacturer of rifles and shotguns in Adelaide, South Australia, from 1947 until the early 1980s. Founded by Jack Warne, also known by its full name Sporting Arms Limited, began by manufacturing single shot 22LR rifles. Sportco purchased ex military Martini Cadet rifles from the Australian Government and converted them to both rimfire and centrefire calibres as well as rebarrelling Lee–Enfield rifles to .303/22 and .303/25.
The BL 13.5 inch Mk V gunMk V = Mark 5. Britain used Roman numerals to identify Marks (models) of ordnance until after World War II. This was the fifth model of British 13.5 inch gun was a British heavy naval gun, introduced in 1912 as the main armament for the new super-dreadnought battleships of the . The calibre was 13.5 inches (343 mm) and the barrels were 45 calibres long i.e. 607.5 inches (15.43 m).
After the civil war, they were organized into seven independent regiments of 18 guns each. Following Greece's entry into NATO in 1952 and the standardization on American calibres in 1953, the 25-pounders, unlike other models, were not retired but reorganised into 13 battalions of eight guns each, as part of divisional artillery formations. In 1957, the influx of American artillery pieces permitted an increase from 8 to 12 guns per battalion.
264 in) variant of the .308 Winchester (7.62×51mm) cartridge, meaning these cartridges can be used in .308 Winchester chambered rifles only requiring different barrels.demigodllc.com: The Case for .260 Remington: A Better Cartridge For Practical Long-Range Shooting by Zak Smith The 6.5 Creedmoor chambering has the traditional 203 mm (1 in 8 inch) or 31.2 calibres right-hand twist rate shares the relative ease of chambering it in arms designed for .
The long rifles used were more accurate and had a longer range than other firearms at that time (300 yards as compared to 80 for standard smooth-bore muskets), but took much longer to load. As they were handmade, calibres varied, requiring differently sized bullets. When his men were done training Morgan used them as snipers, shooting mostly British officers who thought they were out of range, sometimes they killed 10 British in a day.
The Weibel M/1932 was a light machine gun concept of Danish origin and was considered to supplement the Madsen gun in Danish service. It was fed from a 20-round box magazine chambered in the intermediate 7x44mm round. This calibre was considered underpowered for its day but shares the same ballistics as later calibres such as the 7.92×33mm Kurz, 7.62×45mm vz. 52 and 7.62×39mm M43 used in assault rifles.

The UMP is interchangeable between three different calibres: The UMP45, chambered in .45 ACP cartridge The UMP40, chambered in .40 S&W; cartridge The UMP9, chambered in 9×19mm Parabellum cartridge Apart from the different chambering, all versions feature the same design model, the exterior differences being the curved magazine used on the UMP9, while both the UMP40 and UMP45 each use a straight magazine.
The BL 8 inch guns Mark I to Mark VIIMark I to Mark VII = Mark 1 to Mark 7. Britain used Roman numerals to denote marks (models) of ordnance until after World War II. Hence these were the first 7 models of BL 8-inch naval gun. were the first generations of British rifled breechloaders of medium-heavy calibre. They were initially designed for gunpowder propellants and were of both 25.5 and 30 calibres lengths.
The Calibres de France were formalized in an ordinance of 1552.L'histoire mémorable du siège et de la famine de Sancerre (1573) by Jean de Léry, Géralde Nakam p.70 Six standard sizes were defined: the cannon (Canon), the "grand" culverin (Grande couleuvrine), the "bastard" culverin (Couleuvrine bâtarde), the "middle" culverin (Couleuvrine moyenne), the Falconet (Faucon), and the (Fauconneau). The system was expanded by an ordinance dated 27 November 1572, and an edict dates December 1601.
Between 1941 and 1942 three of the ships — La Moquese, Commandant Duboc and Commandant Dominé — were rearmed by the British. Their main armament was replaced by twin quick-firing gun (QF) guns, while La Moqueuse was also fitted with a single QF /40 Mk I high-angle gun. All three also received a single QF 2-pounder pom-pom gun. They retained their original twin 13.2 mm/76 AA guns, while two ships received additional guns of various calibres.
Blackmore, H L, (1976). The Armouries of the Tower of London: The Ordnance, (HMSO, London), p90 This was designed to fire a smooth bore spherical shell weighing 50 pounds. The 8-inch gun was bored out to 10.5 inches and a new built-up wrought iron inner tube with inner diameter of 6.29 inches was inserted and fastened in place. The gun was then rifled with 3 grooves, with a uniform twist of 1 turn in 40 calibres (i.e.
Ibrahim Pasha, the commander of the Egyptian expedition to the Peloponnese. Overall at Navarino, the Allies had 22 ships and 1,258 guns against the Ottomans' 78 ships with 2,180 guns (figures exclude smaller boats and fireships).James (1837) VI.473–89 But the numbers masked major Allied advantages in ship-types, gun-calibres and crew quality. As a result of these, Allied gun-crews could fire more powerful, more frequent and more accurate cannonades than their Ottoman counterparts.
Two days later, on a 'Rover' patrol he torpedoed another vessel, off IJmuiden. On 6 April 1941 over Brest Harbour, France, Flying Officer Campbell attacked the German battleship Gneisenau. He flew his Beaufort through the gauntlet of concentrated anti-aircraft fire from about 1000 weapons of all calibres and launched a torpedo at a height of . The attack had to be made with absolute precision: the Gneisenau was moored only some away from a mole in Brest's inner harbour.
The Allied Data Publication 34 (ADatP-34) NATO Interoperability Standards and Profiles which is covered by STANAG 5524, maintains a catalogue of relevant information and communication technology standards. STANAGs are published in English and French, the two official languages of NATO, by the NATO Standardization Office in Brussels. Among the hundreds of standardization agreements (the total was just short of 1,300) are those for calibres of small arms ammunition, map markings, communications procedures, and classification of bridges.
The majority of medieval cannon were breechloaders, although there was still no effort to standardise calibres. The usual loading equipment consisted of a copper loading scoop, a ramrod, and a felt brush or "sponge". A bucket of water was always kept beside the cannon. Skins or cloths soaked in cold water could be used to cool down the barrel, while acids could also be added to the water to clean out the inside of the barrel.
Fuzes may be delivered fitted to shells or in separate containers, in the latter case the shell itself has a plug that has to be removed before fitting the fuze. Historically, fuzed HE shells were provided with a standard impact fuze that had to be removed and replaced by a time fuze when airburst was required. Whether or not shells are delivered fuzed depends on whether or not the shells are in sealed packaging. Historically smaller calibres, e.g.
They were also mounted on various wheeled carriages to provide the British Army with a long range gun. They all had a barrel of 40 calibres length. The gun was originally designed to replace the older BL 5-inch (127 mm) naval guns. It was optimised for the modern smokeless propellants, such as Cordite, and could be loaded and fired far more rapidly than the BL 5-inch gun while firing a shell only slightly lighter.
Sailor operating 10-barrel rifle calibre gun, with right hand on lever Royal Marines with a Nordenfelt 5-barrel rifle calibre guns, 1890. The Nordenfelt gun was a multiple barrel organ gun that had a row of up to twelve barrels. It was fired by pulling a lever back and forth and ammunition was gravity fed through chutes for each barrel. It was produced in a number of different calibres from rifle up to 25 mm (1 inch).
Manufrance Le Français 6,35 mm «de poche» (first version, without the charger). The Le Français pistol by Manufrance was produced from 1913 till 1969, in a variety of calibres. It was mainly sold in France, primarily to the greater public but also to some officers of the French Army (during the Phony War), and to the French municipal police. In 1912, Etienne Mimard the Head of Manufrance (La Manufacture Française d'Armes et de Cycles de Saint Etienne) started development.
The Treaty of Versailles (signed in 1919) imposed a number of restrictions on pistol barrel lengths and calibres on German arms manufacturers.Bishop (1998), p. 94. Pistols for German government issue or domestic market sales could not have a barrel longer than 4 inches and could not be chambered for 9 mm cartridges. The Weimar Republic banned the private ownership of military-issue or military-style weapons in an attempt to recover valuable arms from returning soldiers.
Both mated a barrel ballistically identical to that of the B-10, to a tracked carriage of the 203 mm howitzer M1931 (B-4). Late in 1936, the Bolshevik Plant delivered an experimental series of six pieces. A number of longer (55 calibres) barrels and a number of barrels with deeper rifling were manufactured. The B-30 barrels were also used for ultimately unsuccessful experiments with pre-rifled shells and with "Ansaldo system" variable depth rifling.
167 in) cartridge (which became known as the 4.25mm Liliput and which is considered obsolete), the Liliput is one of the few pistols that can be owned in the United Kingdom without a license.Firearms Law, Guidance to the Police. Home Office/HMSO London, 2002. Appendix 5, Antique Firearms: Obsolete Calibres The Liliput features in a number of novels by Alistair MacLean, though he incorrectly calls it the "Luger Liliput" and refers to its calibre as ".21".
During World War II Webley air rifles were used for rifle training as well as civilian target shooting and hunting. The Mark II, known as the service air rifle because of its use by the UK military, used break-action with a superimposed barrel locked by bolt action. The detachable barrel was easily interchangeable with others of the three calibres available. The Mark II was discontinued in 1946 and replaced by the Mark III, in production until 1975.
The Armstrong Whitworth 12-inch naval gun of 40 calibres length was designed by and manufactured mainly by Armstrong's ordnance branch, Elswick Ordnance Company. It was intended for the Royal Navy's s, but budgetary constraints delayed their introduction. The first units were instead supplied to Japan. As the Type 41 12-inch (305 mm) 40-calibre naval gun it was the standard main battery on several early United Kingdom-built pre-dreadnought battleships of the Imperial Japanese Navy.
Gun barrel construction The gun was constructed of a toughened mild steel inner "A" tube surrounded by multiple wrought-iron coils, breech-piece and jacket. Rifling was of the "polygroove plain section" type, with 33 grooves increasing from 0 to 1 turn in 50 calibres (i.e. 1 turn in 800 inches) at the muzzle. After a long design and experimentation period beginning in 1873, with four guns became the only ship to mount them, in 1880.
60-pounders deployed in the open during the German Spring Offensive. The HAG became permanent RGA brigades on 1 February 1918, with 51st being designated a 'Mixed' brigade consisting of two batteries of 60-pdrs (137th (Deptford) and 138th (Hampstead)) and four heavy howitzer batteries of various calibres. 51st Brigade moved back to Fifth Army in March.Farndale, Annex M. 137th Hvy Bty was supporting III Corps when the German Spring Offensive fell on it on 21 March.
Saunders, pp. 10–11 A survey conducted in 1603 recorded that Upnor Castle had 20 guns of various calibres, plus another 11 guns split between two sconces or outworks, known as Bay and Warham Sconces. The castle's armament consisted of a demi-cannon, 7 culverin, 5 demi-culverin, a minion, a falconet, a saker, and four fowlers with two chambers each. Bay Sconce was armed with 4 demi-culverin, while Warham Sconce had 2 culverin and 5 demi- culverin.
Kokalis, 224 It was put into production by Denel Land Systems in two versions; 20 x 110 and 20 x 82. The latter model is also available in 14.5 x 114 and conversion between the calibres can be done in the field by swapping the barrel and bolt assembly. The significantly larger 20 x 110 model cannot be converted to another calibre. The rifle was accepted into service with the South African National Defence Force in 1998..
Switching between the two calibres of the NTW (20×82mm and 14.5×114mm) requires changing the bolt, barrel, sighting gear and magazine. (A third variant, the NTW 20×110mm has been developed, but is not designed for barrel calibre switching.) Caliber switching the NTW 20/14.5 can be accomplished in the field without specialised tools. The magazine protrudes from the left side of the receiver. The NTW can be disassembled and packed into two backpacks for carriage.
Close-up of muzzle The barrel is 55 calibres long (L55) and is made of electro-slag refined steel. The bore and chamber are electro-plated with chromium to give a barrel life of 400 effective full charges. The breech mechanism is a split sliding-block breech. One vertically sliding block holds the obturation ring (which is necessary because the propellant charges are combustible cases or bags) and is locked for firing by a second block.
Former gun positions at Verne High Angle Battery, Portland, England Spy Glass Battery, Gibraltar In the late 1880s and early 1890s a small number of guns were adapted as high-angle coast defence guns around Britain : known battery locations were Tregantle Down Battery at Plymouth, Verne High Angle Battery at Portland and Steynewood Battery at Bembridge on the Isle of Wight. The idea behind these high-angle guns was that the high elevation gave the shell a steep angle of descent and hence enabled it to penetrate the lightly armoured decks of attacking ships rather than their heavily armoured sides. To increase accuracy the old barrels were relined and given modern polygroove rifling : 27 grooves with a twist increasing from 1 turn in 100 calibres to 1 turn in 35 calibres after 49.5 inches. These guns fired a special 360-pound armour- piercing shell to a range of 10,500 yards using a propellant charge of 14 lb Cordite Mk I size 7½, remained in service through World War I and were not declared obsolete until 1922.
Changes to the feed mechanism were all that remained, and by the end of the year it was operating at 130 rounds per minute. Continued development was needed to turn it into a weapon suitable for production, which was completed in October 1933. Since acceptance trials had been passed the year before, this became known as the "40 mm akan M/32". Most forces referred to it as the "Bofors 40 mm L/60", although the barrel was actually 56.25 calibres in length, not the 60 calibres that the name implies. The gun fired a high explosive 40 × 311R (rimmed) shell at . The rate of fire was normally about 120 rounds per minute (2.0 rounds per second), which improved slightly when the barrels were closer to the horizon as gravity assisted the feeding from the top-mounted magazine. In practice firing rates were closer to 80–100 rpm (1.3–1.7 rounds per second), as the rounds were fed into the breech from four round clips which had to be replaced by hand. The maximum attainable ceiling was , but the practical maximum was about .
The Calibres de France ("French calibers") was a system of standardization of cannons in France, established by King Francis I of France from about 1525.La Grande Maîtresse, nef de François Ier: recherches et documents d'archives by Max Guérout p.231 The objective was to simplify and codify cannonry, in order to facilitate production. On 26 September 1526, Francis I wrote about the artillerye de mon calibre ("Artillery of my caliber"), and an even earlier mention is known from 1512.
The custom-designed 35-calibres Mk XIII gun had a heavier breech which allowed the trunnions to be closer to the breech and hence the breech did not depress as far when the barrel was elevated. On a new Mk IV mounting, Mk XIII guns could then be elevated to 40° and attain a range of 22,600 yards.Hogg & Thurston 1972, page 168-173 These remained in service until 1945, serving in the home defence of Britain in World War II.
In addition, gun-calibres had been upgraded. The Napoleonic-era had been equipped with 32-pounders on the main gun-deck, 18-pounders on the upper deck and 9- and 12-pounders on the super-structures (quarterdeck and forecastle). In contrast, the guns were now all 24- or 32-pounders (plus a couple of massive 68-pounder carronades on the super- structures). Frigates were either double-deckers of 50–60 guns (known as large frigates) or single-deckers with 24–44 guns.
Treatise on Construction of Service Ordnance 1877, pages 286-287 The gun was rifled on the "Woolwich" pattern of a small number of broad shallow rounded grooves, with 9 grooves increasing from 0 to 1 turn in 35 calibres ( i.e. 1 turn in 437.5 inches). Mark II had an enlarged powder chamber and attained higher muzzle velocity and slightly longer range. This gun was the final development of large British rifled muzzle-loading guns before it switched to breechloaders beginning in 1880.
Mikasa's main battery Pre-dreadnoughts carried guns of several different calibres, for different roles in ship-to-ship combat. The main armament was a main battery of four heavy guns, mounted in two centre- line turrets fore and aft. Very few pre-dreadnoughts deviated from this arrangement. These guns were slow-firing, and initially of limited accuracy; but they were the only guns heavy enough to penetrate the thick armour which protected the engines, magazines, and main guns of enemy battleships.
World War II saw a leapfrog growth in all areas of military technology. Battlefield experience led to increasingly powerful weapons being adopted. Guns with calibres from 20 mm to 40 mm soon gave way to 50 mm, 75 mm, 85 mm, 88 mm, 90 mm and 122 mm calibre. In 1939, the standard German panzer had either a 20 mm or 37 mm medium-velocity weapon, but by 1945 long-barrelled 75 mm and 88 mm high-velocity guns were common.
The types of artillery used varied from nation and time period. The more important types included the Demi- cannon, the Culverin and Demi-culverin, and the Carronade. One descriptive characteristic which was commonly used was to define guns by their 'pound' rating: theoretically, the weight of a single solid iron shot fired by that bore of cannon. Common sizes were 42-pounders, 36-pounders, 32-pounders, 24-pounders, 18-pounders, 12-pounders, 9-pounders, 8-pounders, 6-pounders, and various smaller calibres.
It can change calibres from 5.56 mm to 6.8 mm in minutes at the user level by changing the bolt head, barrel, and magazine. All of the rifle's parts can be easily stripped for cleaning and all of its controls are fully ambidextrous. A three position (safe, semi-auto and full auto) fire selector lever is located over the pistol grip. A charging handle can be installed on either side of the receiver and does not reciprocate when the weapon is fired.
In Orscheid, Wülscheid and Rottbitze, fighting continued for several more days, with the military situation changing several times.Contemporary reports supposedly exist in Stars and Stripes, the official newspaper of the U.S. Armed Forces. Traces of the fighting are still to be seen in the area. There are many craters in the surrounding woods made by U.S. shells of all calibres, plus at Wülscheid one made by the explosion when a German munitions cart was blown up on 10 March 1945 during the retreat.
Under this set-up, they developed in 1870 the first partially mechanised production processes for complicated movements. By the same year, the Manufacture employed 500 people and was known as the “Grande Maison of the Vallée de Joux”, and by 1900, it had created over 350 different calibres, of which 128 were equipped with chronograph functions and 99 with repeater mechanisms. From 1902 and for the next 30 years, LeCoultre & Cie. produced most of the movement blanks for Patek Philippe of Geneva.
5-in-1 blanks are specifically made for theatrical use and are commonly used in real firearms for dramatic effect. 5-in-1 blanks can function in a variety of different calibres, hence the name. Special blank cartridges are also used when the explosive power of a cartridge is needed, but a projectile is not. Blank cartridges were commonly used for launching tear-gas or rifle grenades, though some types of grenades are capable of trapping the bullet of a live round.
These guns succeeded the BL 9.2-inch Mk VIII naval gun and increased the bore length from 40 to 46.7 calibres, increasing the muzzle velocity from to . The Mk IX was designed as a coast defence gun, with a three-motion breech. Only fourteen were built and the Mk X, introduced in 1900, incorporated a single-motion breech and changed rifling, succeeded them. As coastal artillery, the Mk X remained in service in Britain until 1956, and in Portugal until 1998.
In 1905 Meyer joined with fellow watchmaker Johann Studeli to form the partnership Meyer and Studeli (MST). In the same year Meyer won a Bronze medal at the Liege World Fair. The partnership continued to develop new calibres and enter them into more World Fairs, winning Silver Medals at the Milan Fair in 1906 and Brussels Fair in 1910. The earliest identified watch is an unmarked lady's pocket watch containing an MST 41 cylinder escapement that has London silver hallmarks for 1908.
It was intended for static emplacement, and was mounted on a pedestal, allowing for 360° sideways movement. The mount allowed for an angle of elevation of between -1° and 75°. The gun barrel was 45 calibres long, and had 28 grooves (rifling) twisting to the right. The breech block was a semi-automatic horizontal-wedge - the gunner had to manually open it to remove the case from the previous shot, but it closed automatically on the insertion of a new round.
Beginning in the late 1830s, the superior characteristics of the new rifles caused the British military to phase out the venerable .75 calibre Brown Bess musket in favour of muzzle-loading rifles in smaller calibres. Early rifles were non- standard and frequently used adaptations from components of the Brown Bess, including locks and stocks adapted to new rifled barrels. It was not until the late 19th century that the rifle fully supplanted the musket as the weapon of the infantryman.
The SIG MG 50 is a general-purpose machine gun of Swiss origin and was chambered in many calibres. It was designed to replace the Maxim and Furrer M25 guns in service of pre-World War II design so around 1944/51, SIG industries decided to manufacture a series of gas-operated machine guns fed by using drum magazines and ammo belts. The MG50 lost in the trials to the MG51; however, it continued sales for a time. A version chambered in the .
By the middle of World War II, the United Kingdom was making use of 15-inch guns kept as spares for the to arm the last British battleship, . Some World War II-era designs were drawn up proposing another move towards gigantic armament. The German H-43 and H-44 designs proposed guns, and there is evidence Hitler wanted calibres as high as ; the Japanese 'Super Yamato' design also called for 508 mm guns. None of these proposals went further than very preliminary design work.
Gun-howitzer (also referred to as gun howitzer) is a type of artillery weapon that is intended to fulfill both the role of ordinary cannon or field gun, and that of a howitzer. It is thus able to convey both direct and indirect fire. To be able to serve as a howitzer, gun-howitzers are typically built to achieve up to 60–70° of elevation. For effective direct fire, the gun- howitzers typically employ a fairly long barrel, usually not shorter than 30 calibres.
84 In August 1704, an Anglo-Dutch invasion force sailed into the Bay of Gibraltar and rapidly overcame the poorly manned garrison. Don Diego de Salinas, the last Spanish governor of Gibraltar, had repeatedly called for the garrison and fortifications to be strengthened, but to no avail. When Admiral George Rooke's fleet carried out the capture of Gibraltar, his 350 guns were opposed by only 80 iron and 32 brass cannon of various calibres in Gibraltar. Most of the Spanish guns were not even manned.
Carronades were manufactured in the usual naval gun calibres,Twelve-, 18-, 24-, 32-, and 42-pounders, but 6-pounder and 68-pounder versions are known. but were not counted in a ship of the line's rated number of guns. As a result, the classification of Royal Navy vessels in this period can be misleading, as they often carried more cannon than were listed. Cannon were crucial in Napoleon's rise to power, and continued to play an important role in his army in later years.
The 17 cm K 18 in MrsLaf was a towed gun with a barrel 47 calibres long. The 17 cm K 18 in MrsLaf shared the same box trail carriage with the 21 cm Mörser 18. The carriage allowed transport of the weapon over short distances in one piece, whilst for longer distances the barrel was removed from the carriage and transported separately. A series of ramps and winches made removing the barrel a reasonably quick task for its time, but still required several hours.
Machinery was also as in the Chathams. The first ship, later to become Birkenhead, had the same mixed oil-and coal-fired boilers, with the machinery rated at with a speed of , but the second ship (later Chester) had all oil-fired boilers, which boosted power to and speed to . The ships' main armament was ten QF 5.5 in (140 mm) Mark I guns (50 calibres long) to a new design by Coventry Ordnance Works. The guns fired an shell to a range of .
On 4 January 2016, a team of 15-General Operations Force (GOF) members led by two officers discover a cache of weapons comprising two M14 rifles, one Uzi machine pistol, three Colt .45 pistols, one revolver, a pair of handcuffs and 173 bullets of different calibres in Lahad Datu following a tip-off from local villagers when the team was conducting an operation in the area. The weapons are believed to have been buried by surviving militants before they fled across the sea back to the Philippines.
The 1997 law did not ban pistols as such and was drafted in terms of small firearms. British law defines a "pistol" as a firearm with a barrel shorter than or a total length of less than (this definition encompasses revolvers, revolving pistols). Only muzzle-loading pistols—including muzzle-loading revolvers—are permitted; in practice all such firearms use black powder—a Class 1 explosive—as the propellant. Small quantities of muzzle-loading pistols and revolvers in various calibres, which comply with the regulations, are manufactured.
GRP gunhouse is a common feature on modern naval gun turrets, this example being on the frigate . Many modern surface warships have mountings for large calibre guns, although the calibres are now generally between . The gunhouses are often just weatherproof covers for the gun mounting equipment and are made of light un-armoured materials such as glass-reinforced plastic. Modern turrets are often automatic in their operation, with no humans working inside them and only a small team passing fixed ammunition into the feed system.
284 of the Mark X version were built by Vickers, of which 28 examples are known to survive today, all except one fitted on barbette mounts. One in Cape Town is on a disappearing mount. The 9.2-inch Mk XI gun introduced in 1908 increased the bore length to 50 calibres in an attempt to increase the velocity still further, but proved unsuccessful in service and was phased out by 1920. The Mk X was hence the final Mark of 9.2-inch guns in British Commonwealth service.
Winston Churchill felt a NATO standard was more important than any qualities of the weapon itself and overturned the decision by the previous Labour Minister of Defence, Manny Shinwell, who had already announced an intention to move to the .280 and the EM-2. During this time, prototype EM-2s were built in several different calibres: Chambons built two for the 7×49mm "Second Optimum" cartridge and another two for the 7.62×51mm NATO. One of the Chambon prototypes was even rebuilt for the US .
Breda-SAFAT (Società Italiana Ernesto Breda per Costruzioni Meccaniche / Breda Meccanica Bresciana - Società Anonima Fabbrica Armi Torino) was an Italian weapons manufacturer of the 1930s and 1940s that designed and produced a range of machine-guns and cannon primarily for use in aircraft. Based on the M1919 Browning machine gun, the Italian guns were chambered to fire indigenous ammunition with and calibres, predominantly ball, tracer for the 7.7mm, including high-explosive-incendiary-tracer (HEIT) (filled with 0.8 grams of PETN), or armour-piercing (AP) for the 12.7mm.
Like the Mk IV this was based on the 4.5 inch barrel design lined down to 3.7 inches, and using the 4.5 inch size cartridge. However, Colonel Probert changed the barrel to have gradual rifling: the rifling groove depth decreased to zero over the last five calibres of the barrel before the muzzle. This smoothed the two driving bands of a new design shell giving reduced air resistance and hence better ballistic performance, and causing far less barrel wear. The maximum ceiling for the gun was about .
Ball and shot guns were available in a variety of calibres, from 8 bore to 28 bore. The original 12 bore loading from Holland and Holland fired a pure lead bullet that was accurate to ranges up to , Westley Richards developed a 12 bore loading that fired a LT-capped bullet at slightly over which was accurate to ranges up to . Westley Richards 20 bore ball and shot guns fired bullets accurately to , whilst their 28 bore ball and shot guns fired bullets at at ranges of .
A 25-ton version with a bore of 300 inches (30 calibres) and firing a 450-pound projectile was supplied in 1884 to the Australian colony of Victoria, mounted on the gunboat HMVS Victoria.Manual for Victorian naval forces 1887. HMVS Cerberus website This gun was subsequently replaced on Victoria by an 8-inch gun, and in 1887 was mounted at Fort Franklin as a coast defence gun.David Spethman, The Garrison Guns of Australia 1788-1962 page 89, published by Ron H Mortensen, Inala, Qld, 2008.
The 340mm/45 Modèle 1912 gun (13.4 in) was a heavy naval gun of the French Navy. While the calibres of the naval guns of the French Navy were usually very close to those of their British counterparts, the calibre of 340 mm is specific to the French Navy. The built-up gun was designed to be carried by the and classes in quadruple gun turrets, but no ship of these types was completed as a battleship. They were carried by the s in twin turrets.
Hunnicutt p. 196 The main gun—65 calibres long—had a muzzle velocity of 3,700 feet per second (1,130 m/s), with a range of up to 12 miles (19 km).Hunnicutt p. 69 The armor was very thick compared to other tanks of the time, up to 12 inches (305 mm) thick on the front. This was considered heavy enough to provide protection from the German 88 mm gun used as tank and anti-tank guns. The lower hull front had 5.25 in (130 mm) of armor, and the sides 2.5 in (64 mm).
It features parts that dimensionally or otherwise are not interchangeable with the AW rifle series. With an AXMC calibre conversion kit, the AXMC can change calibres in minutes by exchanging the bolts, magazines and barrels. Converting to the 7.62×51mm NATO cartridge, an additional magazine converter must also be fitted within the magazine port to allow the use of an Accuracy International AX308 magazine. A single shroud/firing pin assembly is provided for each multi calibre weapon system and must therefore be installed into the required bolt assembly as part of the conversion procedure.
The Martini Cadet is a centrefire single-shot cadet rifle produced in the United Kingdom by BSA and W.W. Greener for the use of Australian military Cadets..Digger History Although considered a miniature version of the Martini–Henry, the internal mechanism was redesigned by Auguste Francotte to permit removal from the receiver as a single unit. Chambered for the .310 Cadet cartridge (aka: .310 Greener), it was used from 1891 to 1955. They were also sold to the public thereafter, as the BSA No.4, 4a, 4b and 5 in other calibres like the .
These ships were very large, displacing , could only reach , and could only be docked in a single ex-German floating dock, and one dock, Gladstone Dock in Liverpool. The 'J3', the next proposal, saved nearly by reducing the main armament to nine 50-calibres long guns and the main deck armour to . Total armour was less than Hood but with increased power was expected to reach 32 kn. This reduction in size allowed the ship to dock anywhere that Hood could, and to pass through the Suez and Panama Canals.
He hoped that the frustrating talks would be concluded soon; "I hoip seurlie within sax ouilkis (six weeks), we salbe at our wittis end and sooner." Chisholm visited Mary at Sheffield Castle, and took letters to France in April, borrowing £3 from John Lesley, Bishop of Ross. The Bishop kept a note of Chisholm's movements; he returned to Scotland from Dieppe in June 1571, carrying money sent by the exiled Bishop of Glasgow, cannonballs of four different calibres and pikes. These supplies were obtained from Charles IX of France.
To achieve the desired mobility and agility from the engines available the armour protection was sacrificed, a measure of protection coming from being nimble and hopefully from being able to knock out the enemy before they could get a shot in. Although they usually had guns of either 75 mm or 76 mm calibre (the M36 used a 90mm calibre gun), the tank destroyer units were issued with the ancestor of the modern armour-piercing discarding sabot, rounds which made their guns much more powerful than a simple comparison of calibres would suggest.
While information on the Wehrmacht's use of the Krag–Jørgensen is hard to find, it is assumed that it was issued primarily to second line units since the Wehrmacht attempted to only issue firearms in standard calibres to front line troops. It was also issued to the Hird—the armed part of Nasjonal Samling (NS) ("National Unity"), the national-socialist party of Vidkun Quisling's puppet government. It is further likely that the experiments with 7.92 mm ammunition means that the Germans considered a wider use of the Krag–Jørgensen.
"C" Battery, 4th Brigade Royal Artillery, with six guns, served in New Zealand under Captain H.A. Mercer, in March 1861 in the final stages of the First Taranaki War. Captain Mercer again led this battery in the Second Taranaki War until he died leading an unsuccessful attack on a Maori redoubt at Rangiriri in November 1863. In January 1864 "I" battery, equipped with the "new pattern" of 24-calibres, arrived in New Zealand with another six guns. The guns from Victoria were employed from January 1864 onwards to reinforce "C" and "I" batteries.
13 cwt boat gun at Hong Kong Museum of Coastal Defence The RBL 20 pounder of 13 cwt and 15 cwt for sea service was introduced in 1859. It is 2½ feet shorter than the land version giving it a bore of only 54 inches (14.43 calibres), and hence a short stubby appearance. Its short barrel only allowed it to attain a muzzle velocity of 1,000 ft/second. The 15 cwt gun, identifiable by the raised coil in front of the vent slot, was intended for broadside use in sloops.
In late 1936, a plant was built near Nanking to manufacture binoculars and sniper rifle sights. Additional arsenals were built or upgraded to manufacture other weapons and ordnance, such as the MG-34, pack guns of different calibres, and even replacement parts for vehicles of the Leichter Panzerspähwagen. Several research institutes were also established under German auspices, such as the Ordnance and Arsenal Office and the Chemical Research Institute, under the direction from IG Farben. Many of those institutes were headed by Chinese engineers who had returned from Germany.
The cartridges for lever-action rifles have a wide variety of calibres, bullet shapes and powder loads, but they fall into two basic categories: Low-pressure cartridges with rounded bullets, and high-pressure cartridges with aerodynamic pointed ("spitzer") bullets. Some lever actions are not as strong as bolt action or semi-automatic rifle actions. The weaker actions utilize low- and medium-pressure cartridges, somewhat similar to high-powered pistol ammunition. To increase the bullet's energy at the relatively low velocities, these often have larger, heavier bullets than other types of rifles.
It was based on a modified Mauser style long action, and available in a variety of calibres and stock styles. It continued to be made until 1986. The stocks included an 'American' style with a Monte Carlo comb, a 'European' with a straight comb, and a full length 'Stutzen' with many variations of wood, grade, colour, end caps, fillers and chequering. The BSA barrels are recognised as some of the best ever manufactured, with the standard rifle length being 24 inches, whilst the fully stocked 'Stutzen' carbine model was 20 inches.
In common with other Royal Ordnance RML designs of the 1860s, Mark I used the strong but expensive Armstrong system of a steel tube surrounded by a complex system of multiple wrought-iron coils, which was progressively simplified in Marks II and III to reduce costs : Mark III consisted only of A tube, B tube, breech coil and cascabel screw. Rifling was of the "Woolwich" pattern of a small number of broad shallow grooves: 4 grooves with twist increasing from 0 to 1 turn in 40 calibres (i.e. in 320 inches) at the muzzle.
In the common practice of states, explosive weapons are generally the preserve of the military, for use in situations of armed conflict, and are rarely used for purposes of domestic policing. Certain types of explosive weapons may be categorised as light weapons (e.g. hand-held under-barrel and mounted grenade launchers, portable launchers of anti-tank missile and rocket systems; portable launchers of anti-aircraft missile systems (MANPADS); and mortars of calibres of less than 100 mm). Many explosive weapons, such as aircraft bombs, rockets systems, artillery and larger mortars, are categorised as heavy weapons.
The latest incarnation of the Panzerfaust 3, the PzF 3-IT-600, can be fired from ranges up to 600 metres thanks to an advanced computer-assisted sighting and targeting mechanism. As of 2005, there were two additional models in the development or testing stage, both relying on smaller, and therefore lighter, warheads. These were the Rückstoßfreie Granatwaffe RGW (Recoilless Grenade Weapon) in calibres 60 and 90 millimetres. Both new weapons are expected to help facilitate the transition in German military doctrine from preparation for major tank battles to urban and low-level warfare.
Classified as a Waffenträger (weapons carrier) by the RLM, which the WT suffix denoted, in a similar role to that of the American YB-40 Flying Fortress "gunship" heavy defensive fighter conversion for the USAAF. Primary mission was to provide normal 323 cargo formations with heavy defensive protection. No cargo carrying ability. "Solid" nose with 20mm cannon turret, two additional wing turrets plus up to ten other machine guns/cannon of varying calibres firing from standard and new waist/beam positions. 1.3 tonnes of armour plating was added across the entire airframe.
The Sardinians led by Vittorio Francesco Filippo di Savoia, Marquis of Susa, the brother of the King Charles Emmanuel III, entrenched themselves along the heights of Villafranca. Their natural defences were formidable: the attackers, hemmed in by cliffs and precipices, faced a difficult climb up over rocks and boulders, in plain sight of Sardinian guns. The fortified camp was equipped with more than 80 guns of all calibres, landed from English ships stationed in the harbor, which were arranged in eleven batteries. Sardinian forces counted fourteen battalions of infantry.
SMS Radetzky Pre- dreadnoughts, from the period 1890 to 1905, were typically fitted with 3 or 4 different calibres of weapon. The main guns were usually approximately 12-inch caliber, secondary weapons usually 6-inch but typically in the range 5-inch to 7.5-inch. Guns smaller than 4.7-inch are usually considered "tertiary". (Many pre-dreadnoughts also carried 9.2 to 10-inch "secondary" guns, but these are usually treated instead as a mixed-caliber main armament.) Secondary guns were "quick firers", and could fire 5 to 10 rounds per minute.
In fact, this rifle is available in almost every modern calibres. A limited edition called the 150 year anniversary Ritter Von Mannlicher were run in 1998 in the original 6.5×54mm M.S.cartridge. Although the modern "Classic" Steyr-Mannlicher rifles still incorporate some original features, like the butter-knife bolt handle, the distinctive actions and rotary (spool) magazines of the original Mannlicher–Schönauer rifles are no longer used. High production costs and the difficulty of fitting telescopic sights to the rifle's split receivers eventually resulted in a decision to terminate production in 1972.
The BL 13.5 inch naval gun Mk I ("67-ton gun") was Britain's first successful large breechloading naval gun, initially designed in the early 1880s and eventually deployed in the late 1880s. Mks I - IVMk I = Mark 1, Mk II = Mark 2, Mk III = Mark 3, Mk IV = Mk 4. Britain used Roman numerals to denote marks (models) of ordnance until after World War II. Hence this article covers the first four models of British 13.5 inch guns were all of 30 calibres length and of similar construction and performance.
The resulting steam was taken off by a flexible tube to a condenser container—this had the dual benefits of avoiding giving away the gun's location, and also enabling re-use of the water, which was very important in arid environments. In British service, the Vickers gun fired the standard .303 inch cartridges used in the Lee–Enfield rifle, which generally had to be hand-loaded into the cloth ammunition belts. There was also a 0.5 in calibre version used as an anti-aircraft weapon and various other calibres produced for foreign buyers.
From 1890 new improved German guns were installed, an underwater barrier was built in 1874–79,Berg 1997: 10 and an underwater torpedo battery was constructed. The main armament was three 28 cm calibre guns(11 inch) manufactured by Krupp. There were also a number of guns with smaller calibres (15 cm and 57 mm) on the mainland. An underwater barrier went from the main islet of Kaholmen and south-west to Hurum on the western side of the fjord, thus making it impossible for large vessels to sail west of the fortress.
The newer designs of 12-inch gun mounting had a considerably higher rate of fire, removing the advantage previously enjoyed by smaller calibres. In 1895, a 12-inch gun might have fired one round every four minutes; by 1902, two rounds per minute was usual. In October 1903, the Italian naval architect Vittorio Cuniberti published a paper in Jane's Fighting Ships entitled "An Ideal Battleship for the British Navy", which called for a 17,000 ton ship carrying a main armament of twelve 12-inch guns, protected by armour 12 inches thick, and having a speed of 24 knots (28 mph/44 km/h).
Shortly after taking office, Fisher set up a Committee on Designs to consider future battleships and armoured cruisers. The committee's first task was to consider a new battleship. The specification for the new ship was a 12-inch main battery and anti-torpedo-boat guns but no intermediate calibres, and a speed of which was two or three knots faster than existing battleships. The initial designs intended twelve 12-inch guns, though difficulties in positioning these guns led the chief constructor at one stage to propose a return to four 12-inch guns with sixteen or eighteen of 9.2-inch.
Campo-Giro obtained his first patent in 1904 for Una pistola automática de calibre 9mm. de nuevo sistema ("An automatic pistol of 9mm calibre of a new system"). He followed this in 1911 with a patent for a self-loading carbine. In 1912 he obtained a registered design for his pistol. In November that year lodged another patent for Una pistola sistema Campo-Giro con amortiguador del choque en el retroceso, para los calibres 11,25, 9mm largo, 9mm corto y 7,65mm ("A Campo-Giro system pistol with a shock-absorber for recoil in calibre 11.25, 9mm largo, 9mm Kurz and 7.65mm").
In 1971, the owning family opted to join General Watch Co, the newly created sub-holding of ASUAG, in order to consolidate their efforts with others. The introduction of cheap and reliable automatics and Quartz watches from Japan (under the rules of their strategic management: see Strategic management ) stopped Certina's expansion. The restructuring involved the abandonment of their own manufacture of Certina calibres, and by the end of the 1970s, Certina operations were moved to Biel/Bienne and the entity Edox & Technos. Under the new management, Certina managed to hold on to some of their properties, especially in the Scandinavian countries.
Jim Wilson "A Perfectly Delightful Cartridge: 7×57 mm Mauser" American Rifleman November 2009 pp.53–55 It was subsequently adopted by several other countries as the standard military cartridge, and although now obsolete as a military cartridge, it remains in widespread international use as a sporting round. Many sporting rifles in this calibre were made by British riflemakers, among whom John Rigby was prominent; and, catering for the British preference for calibres to be designated in inches, Rigby called this chambering the .275 bore after the measurement of a 7 mm rifle's bore across the lands.
An extensive range of tests were carried out on a wide variety of shells of various calibres, as well as on mines, projectiles, bombs (up to 500 kg) and spray equipment. The substances tried included arsenic oil, hydrogen cyanide, mustard gas (Lost), Tabun, Sarin, cyanogen chloride, phenacyl chloride, Adamsite, Aeroform, Excelsior (10-chlor-9,10-dihydroacridarsin) and many others. Chemical munitions were filled at the so-called "fog-filling point" (Nebelfüllstelle), which had a tank capacity for about 3,000t of chemical. At this filling point there was a large underground facility that was partly linked with walkways.
5 The East Tilbury Blockhouse was built partly with stone taken from St Margaret's Chapel in Tilbury, which was dissolved in 1536. Its form is not known but it probably consisted of a brick and stone structure, perhaps in a D-shape, with a rampart and ditch to enclose its landward side. It was recorded as having fifteen iron and brass cannon of various calibres in 1540; these had been increased to 27 by 1539–40. It had a small permanent garrison, consisting of a commander and his deputy, a porter, two soldiers and four gunners.
This situation continued until the late 1990s, when fullbore rifles of calibres up to .270 Winchester were permitted to be licensed for the purposes of deer hunting on humane grounds (prior to this, only the .22–250 cartridge was available for deer hunting and it was felt to be only barely capable of this task). All other firearms held in custody remained there, until the repeal of the Garda policy following a high court case in 2004 taken by Irish shooter Frank Brophy to obtain a licence for an Olympic target shooting pistol succeeded and the licence was granted.
Thorsten Nordenfelt and his brother-in-law started a small business to trade Swedish steel for British rails in 1887. Later on he founded Nordenfelt Guns and Ammunition Company, ltd to develop a machine-gun designed by Helge Palmcrantz that would be referred to as the Nordenfelt gun. His company also designed a range of anti- torpedoboat guns in calibres from 37 to 57 mm, that were produced in Erith, Kent, Stockholm and Spain. Under pressure from Rothschild and Vickers his company merged with Maxim's in 1888 to form The Maxim Nordenfelt Guns and Ammunition Company.
In the British navy, many smaller 64-pounder smoothbore guns were converted to rifled weapons: the converted guns were called RMLs, whilst weapons manufactured with rifling were termed muzzle-loading rifles. This distinction did not survive with the larger calibres, which were generally all called RMLs. Many artillery pieces were converted from older smooth bore weapons once technical problems in strengthening the original cast iron body had been overcome. The widely adopted solution, invented in 1863 by William Palliser, consisted of enlarging the bore to accept a wrought iron tube (called the A tube) into which the rifling had been cut.
An AK-74M muzzle device venting propellant gases The rifle received a new barrel with a chrome-lined bore and 4 right-hand grooves at a 200 mm (1:7.87 in) or 37 calibres rifling twist rate. The front sight base and gas block were redesigned. The gas block contains a gas channel that is installed at a 90° angle in relation to the bore axis to reduce bullet shear at the port hole. A pair of support brackets are cast into the gas block assembly and are used to attach a BG-15c or GP-25 underslung 40 mm grenade launcher.
The D-10 is a high-velocity gun of 100 mm calibre (bore diameter), with a barrel length of 53.5 calibres. A muzzle velocity of 895 m/s gave it good anti-tank performance by late-war standards. With its original ammunition, it could penetrate about 164 mm of steel armor plate at 1,000 m, which made it superior to the German 75 mm KwK 42 mounted on the Panther tank as well as the Tiger I's 88 mm KwK 36 gun. Testing against Panther tanks at Kubinka showed the D-10T could penetrate the Panther's glacis up to 1500 m.
"Super Sniper Kills Taliban 1.5 Miles Away" 3 May 2010 Sky News In addition to its military role, it is increasingly used by hunters and civilian long-range shooting enthusiasts. The .338 Lapua Magnum is capable of taking down any game animal, though its suitability for some dangerous game (Cape buffalo, hippopotamus, white rhinoceros, and elephant) is arguable, unless accompanied by a larger "backup" calibre: "There is a huge difference between calibres that will kill an elephant and those that can be relied upon to stop one."Robertson, K: The Perfect Shot, Safari Press, Inc, Long Beach, 1999:p. 50.
The French had agreed with the Belgian rebels that the latter would not participate in the battle. Following the French army's first intervention in 1831, the Dutch withdrew from Belgium but left a garrison in Antwerp Citadel, from which they bombarded the town. The Armée du Nord and its siege specialist François, Baron Haxo took 24 days to take this citadel and return it to Belgium. Leopold I of Belgium gave France several cannons of different calibres as thanks for this action and the French Chamber of Peers offered Gérard an épée d'honneur ("sword of honour").
The headland separating the western end from East Whale Bay holds the remains of fortifications that housed a coastal artillery battery, with another on the high ground behind. Horseshoe Bay itself lies in the danger area behind the butts of the rifle range of , and the western end of the beach is littered with bullets fired from Enfield, Snider–Enfield, Martini–Henry, Lee–Metford, and Lee–Enfield rifles and other weapons of similar calibres. However, this range is no longer used due to the limited range of the 5.56mm NATO rifle cartridge, which has been used for the last three decades.
The 7.5×55mm Swiss or GP 11 (or unofficially 7.5×55mm Schmidt–Rubin) is a cartridge developed for the Swiss Army by mechanical engineer Lt. Col. Eduard Rubin for rifles based on Rudolf Schmidt's action design. The ammunition used by the Schmidt–Rubin Model 1889 rifle was one of the first to use 7.5 mm copper-jacketed rounds similar to those used today. The GP90 7.5×53.5mm round designed by Rubin was revolutionary in that the most popular military calibres used in Europe at the time were around 10 to 14 mm as opposed to 7.5 mm of the Schmidt–Rubin ammunition.
Krupp horizontal sliding block (left side) breech on large gun exhibited at the Centennial Exhibition, Philadelphia, 1876. Diagram of the horizontal sliding wedge. The German company Krupp in contrast, adopted "Horizontal sliding block" breeches, rather than screw breeches, for all artillery calibres up to 16 inch naval guns. This was similar in some ways to the original "Armstrong screw"; the shot and powder cartridge were inserted through the open rear end of the breech into the gun bore, and a steel block was slid home into a horizontal slot cut through the breech to close the rear end of the breech.
This set a new standard for artillery, and made firing cycles measured in seconds rather than minutes possible. Britain used brass cartridge cases for all calibres up to 6 inches in the late 1880s and early 1890s. However, British-designed quickfiring ("QF" in British terminology, which became synonymous with charges in metal cartridge cases) continued to use screw breech blocks, but with their function merely to lock the cartridge in place rather than provide obturation. The powerful backward force generated by 6-inch QF guns still required a strongly seated breech screw with as much thread as possible.
All of those who could would have joined their regiments for the battle. Cromwell states that "as to sound men [...] about 7,500-foot and 3,500 horse", while the modern historian Trevor Royle estimates that a little over 12,000 were fit for action; Reid gives 12,080. In addition both sides fielded a number of artillery pieces, but details of the number and calibres have not survived other than that the English had 22 field and siege guns with only the field guns taking part in the battle; and the Scots a total of 32 with most not firing during the action.
Following the integration of the Zimbabwe Defence Forces, weapons and ammunition shortages remained acute. Serious logistical difficulties arose from the parallel employment of Western and Soviet weaponry, which were of different gauges and calibres, often within the same battalion. In August 1981, a sabotage action most likely carried out by South African Special Forces or disgruntled Rhodesian servicemen destroyed most of Zimbabwe's ammunition stocks. Plans for future procurement were put on hold as the National Army (ZNA) was still demobilising troops and remained uncertain of future manpower levels or the amount of funding available for a replacement inventory.
Bear hunt in Dalarna, Sweden, early 20th century. Hunters carrying firearms tend to favour calibres large enough to inflict as much tissue and bone damage as possible, as grizzly and brown bears can generally withstand a number of direct shots to the limbs or torso without ceasing their attack. Bears have the ability to dramatically lower their heart rate when hibernating and will readily do so if injured, as a defense mechanism against blood loss. Hunters pursuing the animal deliberately might use a caliber larger than they would for the deer, elk and caribou that commonly co-inhabit the same area.
A later forensic ballistics expert cast doubt on whether Craig could have hit Miles if he had shot at him deliberately: The fatal bullet was not found. Craig had used bullets of different undersized calibres, and the sawn-off barrel made it inaccurate to a degree of six feet at the range from which he fired. Secondly, there was controversy over the existence and meaning of Bentley's alleged instruction to Craig, "let him have it, Chris". Craig and Bentley denied that Bentley had said the words while the police officers testified that he had said them.
Its strategic position dominated the channel through which shipping still passes today to avoid shallow bars close to the banks. In 1644 it was already garrisoned by twenty soldiers, ten gunners and a chief of artillery, with five cannons, but the works were only completed in 1653. In 1735, the fort was reported as being in a good state of repair, but its artillery was reduced to 2 pieces of 24-gauge cannon and another 12 of various calibres that were out of service. Repair works were carried out in the middle of the same century, including the application of tiles in the small chapel.
Mk X gun on Mk II "straight-back" truck In June 1916 Elswick produced a more sophisticated turntable mounting with a loading platform, on a "straight-back" truck which mounted the gun much higher. This was lowered to the ground for firing, had outriggers for stability, allowed 360° traverse and elevation to 30°.Clarke 2005, page 36 The more modern Mk X gun was mounted on this design, together with 2 Mk X variants intended for Australian coast defence (Mk XT), 4 Vickers 45-calibre guns (Mk XIV) which were originally intended for a foreign order, and a specially developed 35-calibres railway gun (Mk XIII).
The Allies had a substantial superiority in front-line combat vessels: 10 ships of the line to the Ottomans' three. This advantage was only partially offset by the Ottomans' seven double-deck frigates against one Allied vessel of this kind. The great majority of the Ottoman–Egyptian fleet were smaller vessels – 58 corvettes and brigs – which were of little use against the Allied heavyweights: they had much smaller firepower, and, their decks being lower, could easily be dismasted by raking fire. In addition, the Ottoman–Egyptians mainly deployed smaller-calibre guns than the Allies (often the guns discarded by the Allies when they upgraded their own calibres).
The Nagorno-Karabakh Defence Army's equipment consists of infantry, tanks, artillery and anti- aircraft systems. The Karabakh army's heavy military hardware includes: 186DeRouen, Karl and Uk Heo (eds.) Civil Wars of the World: Major Conflicts since World War II. Santa Barbara, California: ABC-CLIO, 2007, p. 151.Hans- Joachim Schmidt, "Military Confidence Building and Arms Control in Unresolved Territorial Conflicts," PRIF Reports No 89, Frankfurt am Main, 2009, p.12. tanks, 68 armoured vehicles, 98 artillery pieces of calibres over 122mm, 44 multiple rocket launchers (most likely BM-21 Grad), and a anti-aircraft defence system of an unspecified type WM-80, Scud-B: at least 4 launchers.
After the Dutch victories, Javanese-smithed cannons of Makassar, Ternate, and the surrounding islands were taken as reparations, considered by the Dutch as made of bronze superior to their own, and subsequently melted down and recast in Dutch standard calibres and bores.John Pemberton, On the subject of "Java", Cornell University Press: 1994, , 333 pages Culturally, Javanese bronze cannons and their regional derivatives were traditionally part of a dowry, and offering a poor-quality cast bronze cannon was a supreme insult. Brunei and Malaysia retain the tradition of a token cannon as a dowry for weddings, and many celebrations are opened with a celebratory shot.
This class of ammunition is especially useful for the smaller calibres of guns, such as 3-pounder (1.4 kg), 6-pounder (2.7 kg) and field guns, but Messrs. Krupp also employ metallic cartridge cases for the largest type of gun, probably on account of the known difficulty of ensuring trustworthy obturation by any other means practicable with sliding wedge guns. The charges for these cases are made up in a very similar manner to those already described for breech loading. Where necessary, distance pieces formed of papier-mâché tubes and felt wads are used to fill up the space in the case to prevent any movement of the charge.
Recuerdos de un hecho glorioso, Por esos mundos, No 161, June 1908, p. VIII–X. The captain of the Spanish boat asked the British ships the names of their captains, and on receiving no answer but a volley of rifle fire, he put the town on alert. With the defenders forewarned, Cooke abandoned his ruse and after refloating Sybille the following morning, ordered a bombardment of the fort protecting the harbour. This had little effect, though later the Spanish recovered at least 450 cannonballs from different calibres, and Malcolm then attempted an amphibious landing in order to storm the landward side of the fort.
They also scaled it up to larger calibres, particularly for the Royal Navy as a 0.5 inch model. 75mm mountain gun (1900) Vickers & Maxim also introduced one of the first cannons to have an hydraulic recoil absorbing mechanism: in 1900 they produced a small 75 mm cannon that used two cylinders mounted alongside the barrel. Vickers was involved in the production of numerous firearms. The British tested John Pedersen's design for a semi-automatic rifle between World War I and World War II. Vickers made a British version of the rifle, and their version of the Pedersen rifle usually goes by the name "Vickers Pedersen Rifle".
Other calibres, including 5.45×39mm and 6.8mm Remington SPC were planned. It features an ambidextrous safeties, magazine release (right side, left side, and "AK" style), bolt release and charging handle, as well as the ability to change which side spent casings are ejected, a quick-change barrel which can be removed and replaced in seconds without any tools, Picatinny rails, and a foldable telescopic stock. The lightweight barrel is chrome lined and manufactured by the hammer forging process at the Beretta factory in Gardone Val Trompia, Lombardy. Barrel lengths for this rifle are 16 in (40.6 cm) for its standard barrel, and a 12 in (30.48 cm) barrel for special operators.
Like the Type 23 frigate it will replace, the Global Combat Ship will have an acoustically quiet hull for anti-submarine warfare and fitted with an Ultra Electronics Type 2150 next generation bow sonar and a powerful Sonar 2087 towed array. The Global Combat Ship will also be fitted with guns of various calibres. Instead of the RN's current 4.5 inch Mark 8 naval gun, the Global Combat Ship will be equipped with a NATO-standard BAE 5 inch, 62-calibre Mark 45 naval gun. Smaller guns include two Phalanx CIWS, two 30mm DS30M Mark 2 Automated Small Calibre Guns and a number of miniguns and general-purpose machine guns.
During the 1930s both Breda and SAFAT (a division of FIAT) were tasked with producing designs for a new range of machine-guns for use in aircraft of the Regia Aeronautica, the offering from Breda being preferred. FIAT contested the decision but lost, resulting in the sale of SAFAT to Breda to form Breda- SAFAT. Despite the aim of producing an airborne machine-gun equal or superior to other similar weapons, the use of low propellant capacity rounds resulted in significantly lower muzzle velocities than other weapons of similar calibres. Other inadequacies included high weight and modest rates of fire as well as the ineffectiveness of the HEIT high explosive round.
The term QF hence referred to both the breech- sealing mechanism and the method of loading propellant charges. Ordnance of other countries employed other techniques, and hence this description and distinction is limited to British ordnance. Following the early success of the light QF Hotchkiss and Nordenfelt guns in the 1880s, the Royal Navy implemented QF guns in all calibres up to 6 inch in the 1890s, and also converted various 4 inch and 6 inch BL guns to QF under the designation QFC. This all-QF era ended in 1901 with the BL 6 inch Mk VII gun and a swing back to BL guns.
The LRSVM Morava (Serbian: Лансер Ракета Самоходни Вишецевни Модуларни (ЛРСВМ) Морава - Lanser Raketa Samohodni Višecevni Modularni (LRSVM) Morava) is a modular, multi-calibre, multi-pod self-propelled multiple rocket launcher designed and developed by the Serbian Military Technical Institute in Belgrade (VTI). The system is designed to offer subsystem modularity, enabling integration with wheeled or tracked platforms to fire unguided rockets of various calibres to engage targets at ranges between 8 km and 40 km. As of November 2019, the Morava is in service with Serbian Armed Forces on a FAP 1118 4 x 4 cross-country truck and with the United Arab Emirates (UAE) on a Nimr 6 × 6 chassis.
Creating a magazine for the 7.62×53R was problematic, and Valmet opted for using a modified Lahti-Saloranta M/26 magazine for the 7.62×53R version. The trial rifle turned out very accurate, and a small batch was manufactured for the civilian market before the merger of Sako and Valmet. The produced rifles however didn't yet incorporate all of the features developed during the development, such as the multi-calibre rifle patent (Finnish patent № 72807), which featured an aluminium bedding block (chassis) to which barrelled actions of different calibres could then be quickly changed. The produced rifle was meant to be a military sniper rifle in many of its features.
The castle consists of a two-storeyed main building protected by a curtain wall and towers, with a triangular gun platform projecting into the river. It was garrisoned by about 80 men with a peak armament of around 20 cannon of various calibres. Despite its strategic importance, the castle and the defences of the Thames and Medway were badly neglected during the 17th century. The Dutch Republic mounted an unexpected naval raid in June 1667, and the Dutch fleet was able to breach the defences, capturing two warships and burning others at anchor in the river at Chatham, in one of the worst defeats suffered by the Royal Navy.
The T29 was based upon a lengthened version of the T26E3 chassis and featured heavier armor, an upgraded Ford GAC engine producing about gross, net, more comfortable controls for the driver,Hunnicutt, Firepower, p. 72 and a massive new turret incorporating the high-velocity 105 mm gun T5. It weighed approximately unstowed and combat loaded. Its maximum armor thickness was 279 mmHunnicutt, Firepower, p.198. compared to 180 mm on the German Tiger II while its 105 mm gun was 7.06 m longHunnicutt, Firepower, p.216. continental length - from rear face of breech to muzzle (66 calibres, 105L67) compared to the 6.29 mJentz & Doyle, Kingtiger Heavy Tank 1942-45, p.8.
The Northern Fort, just to the southwest of Makung, deployed three Armstrong cannons, and was flanked by a number of subsidiary positions in which the Chinese had deployed a dozen rifled French Voruz cannon of various calibres. The Southern Fort, or Dutch Fort (it had been built by the Dutch in the seventeenth century), was armed with two 22-centimetre and two 14-centimetre smoothbore cannon. A third battery, sited on Observatory Island just inside Makung Bay, also covered the entrance to the bay, which had also been blocked by a barrier of chains. The Observatory Island battery was armed with two Armstrong cannon and a Chinese 20-centimetre cannon.
The 105mm is also capable of firing the Cockerill Falarick 105 Gun Launched Anti-Tank Guided Missile (GLATGM). Elevating to +42° the weapon delivers exceptional engagement capability in complex situations, and the GLATGM permits hard and Point target to be engaged at extended ranges (up to 5 km). The mounting of this type of system allows for flexibility in logistics with the various calibres already in common use with NATO and other major military powers. This is the first time that any company has conceived of mounting this type of system aboard a small, fast and stealthy catamaran that with only a 1-meter draught makes it ideally suited for the confines of coastal waterway operations.
Unlike other London gunmakers, W.J. Jeffery & Co offered modern big-game hunting rifles in the medium price bracket. In order to compete with his biggest competitors, John Rigby & Company and Westley Richards, Jeffery outsourced to several Birmingham based rifle manufacturers including Saunders, Ellis, Webley, Tolley and Leonard bros, as well as Turners of Reading, John Wilkes and others in addition to sourcing components from abroad. By 1905 the firm was producing large numbers of mid-priced nitro express double rifles, both in its own and other calibres. By the time of William Jeffery's death in 1909 they were probably the largest marketer of double rifles within the UK, with large numbers being used in Africa and India.
All of Virant's crew were soon killed or wounded and he was knocked unconscious by a metal fragment to the head. The next two ACAVs were hit by RPGs before they could turn to engage the VC, while the 5th ACAV was protected by a roadside advertising sign. The remaining tanks and ACAVs were stretched out along the highway and began firing on the numerous VC in the village and areas west of the highway and were met by a constant volley of RPGs and machine gun and AK-47 fire. The tanks fired canister shot while the other crewmen fired off their M60s and 0.50 Calibres until they burnt out the barrels and exhausted their ammunition.
In this way, as a result of the prevailing circumstances, Brandenburg's defences were formed along the line from Köpenick, via Berlin, Spandau, Oranienburg, Kremmen, Fehrbellin and Havelberg to the River Elbe. In addition the garrison of Spandau Fortress was reinforced from 250 to 800 men; it also had 24 cannon of varying calibres. In Berlin the garrison was increased to 5,000 men (including the Leibdragoner ("dragoon bodyguard") dispatched by the Elector from Franconia and the reinforcements sent from the province of Westphalia at the end of January). The Swedes, however, remained inactive and failed to take advantage of the absence of the Brandenburg army and occupy wide areas of the Margraviate of Brandenburg.
In 1861, in response to the French warship building programme initiated by Emperor Napoleon III, the British Board of Admiralty selected seven wooden two-decked second-rate warships currently under construction for conversion to armoured warships. The first four, which were converted with all possible speed, were completed as and the ships, , and . The last three were intentionally delayed until assessment could be made of the first four, and as a result of this assessment Royal Alfred, Zealous and Repulse were completed on different lines to the earlier ships, and, indeed to each other. In the 1860s rapid changes were taking place in the technology of armament production, and calibres were increasing by about an inch per year.
The RBL 20 pounder of 16 cwt for land service was introduced in 1860. It has a bore of 84 inches (22.36 calibres) and hence has the appearance of a typical field gun. After it became obsolete for regular Royal Artillery use, a small number were re-issued to Volunteer Artillery Batteries of Position from 1889, alongside 16-pounder RML guns and 40 Pounder RBL guns.Report on the Account of Army Expenditure from 1888–1889, The National archives, WO33/50 The 1893 the War Office Mobilisation Scheme shows the allocation of twelve Artillery Volunteer position batteries equipped with 20 Pounder guns which would be concentrated in Epping, Essex in the event of mobilisation.
The Mendeleev Tank was exceptionally well armed for tank design concept at its time. It was slated to have a Canet naval gun with 51 rounds of ammunition, mounted directly at the front of the tank,much larger than the common calibres of tanks in both World War I and World War II. For comparison, the armament of the British Mark IV tank was two 57 mm QF 6-pounder 6 cwt Hotchkiss guns. The gun was able to swivel left and right as well as elevate and depress. In addition, the gun was supposed to feature a recoil system rather than be placed on a fixed rigid mount, a concept very advanced for the time.
152 mm has been a Russian calibre since World War I, when Britain supplied 6 inch Howitzers and Russia purchased 152 mm guns from Schneider (probably derived from the 155 mm Gun Mle 1877/16) for the Imperial Army. The new gun-howitzer, was a replacement of the pre-war ML-20 gun-howitzer (the 152 mm howitzer M1937) and various World War II era 152 mm field howitzers, Model 09/30, Model 1910/30, Model 1938 M10 and Model 1943 D-1. By Soviet definition, a 152 mm howitzer is 'medium'-calibre artillery. It was designated a 'gun-howitzer' because its muzzle velocity exceeded 600 m/s, and its barrel length exceeded 30 calibres.
British 9.2 inch guns originated from a request by the Admiralty in 1879 for a gun comparable to Krupp's 24 cm (9.45 inch) gun at the time. The Admiralty submitted its request to the Committee on Ordnance, which was considering returning to breech- loading artillery after Britain's brief return to muzzle-loaders in the 1860s and 1870s. A new breech-loading gun with a 9.2-inch (234 mm) bore, firing a 380-pound projectile was calculated to be suitable.Hogg & Thurston 1972, page 164 A total of 19 Mk I and Mk II guns of 26 calibres were made starting in 1881, but after lengthy delays and modifications still proved unsatisfactory; none made it to sea.
Seen mounted on a sponson on third class cruiser HMS Cossack circa. 1900 Mk II followed the early weakly made and less powerful Mark I 80-pounder and introduced a 100-pound projectile, which became standard for British 6-inch guns until 1930. It consisted of a much thicker steel barrel with wrought-iron jackets shrunk over it and as originally introduced weighed 81 cwt (9720 pounds). The gun proved to be too weakly constructed, and 5 steel chase hoops were added to strengthen it and the gun was shorted by 12 inches to rebalance it, resulting in a bore length of 144 inches (24 calibres) and final weight of 89 cwt (9968 pounds), or 4½ tons.
Gustloff-Werke products included 7.92 mm calibre Panzerbüchse 39 anti-tank rifles, 7.92 mm calibre MG 42 machine guns, gun carriages for 20 mm calibre Flak 38 anti-aircraft guns, and various calibres of small arms ammunition. The firm continued to build bicycles, weapons and cars until 1945. In 1946, by order of the Soviet Military Administration in Germany the manufacturing plant was partially dismantled and transported to the Soviet Union (USSR) as part of the Soviet reparations programme for the damage inflicted on the USSR by Germany in the Second World War. In 1947 the factory was integrated into the Soviet Sowjetische Aktiensgesellschaft Awtowelo (SAG Awtowelo or "Soviet Avtovelo Company Limited").
Mks I and II were several early proof guns that did not enter British service and Mk V was not made. Limited numbers of 25.5 and 30 calibres guns were produced. By 1885 the Royal Navy abandoned the 8-inch gun in favour of the 9.2 inch and later the 7.5 inch gun for cruisers, until 1923 when the restrictions of the Washington Naval Treaty led Britain to develop the Mk VIII 8-inch gun in order to arm heavy cruisers with the largest gun allowed by the Treaty. In the interim Elswick Ordnance continued to develop 8-inch guns in 40 calibre and 45-calibre lengths for export, mainly to Japan.
303 calibre bolt-action magazine Lee–Metford, which gave a considerably higher maximum rate of fire. Consequently, to avoid having three different rifle calibres in service, the Enfield–Martinis were withdrawn, converted to 0.45 calibre, and renamed Martini–Henry Mk IV "A", "B" and "C" pattern rifles. Some 0.303 calibre black-powder carbine versions were also produced, known as the Martini–Metford, and even 0.303 calibre cordite carbines, called Martini–Enfields (the former name for the type of action and the latter name for the pattern of rifling). During the Martini–Henry's service life the British Army was involved in a large number of colonial wars, most notably the Anglo-Zulu War in 1879.
The Br-5 mortar was a calibre towed mortar with a barrel 14.2 calibres long. The Br-5 mortar shared the same tracked, box trail carriage as the 152 mm gun M1935 (Br-2) and the 203 mm howitzer M1931 (B-4). The carriage allowed transportation of the weapon over short distances with the speed of , for longer distances the barrel was removed from the carriage and transported separately on a special wheeled cart, the Br-10, a speed of was possible with the barrel removed.The artillery department of the Red Army (Главное артиллерийское управление РККА), 203-mm howitzer 1931 (B-4), 280-mm mortar 1939 (Br-5) and 152-mm gun 1935 (Br-2) service manual (203-мм гаубица обр. 1931 г.
The French and their Spanish allies were besieged in Saigon by a Vietnamese army around 32,000 strong under the command of Nguyen Tri Phuong. The Vietnamese siege lines, 12 kilometres long, were centred on the village of Ky Hoa (Vietnamese: Kỳ Hòa), and were known to the French as the 'Ky Hoa lines'. Ky Hoa itself had been transformed into a formidable entrenched camp: > The first objective was the capture of the entrenched camp of Ky Hoa. This > was a rectangle measuring around 3,000 metres by 900 metres, divided into > five compartments separated by traverses and enclosed within walls three and > a half metres high and two metres thick. The camp was armed with more than > 150 cannon of all calibres.
The Gun and some of its German crew in 1918 The sequence of firing a round was as follows:- Load – the gun was run back on its mountings with the breech in under the shelter. In here was the ready-for-use ammunition – shell and cartridge case (German guns had the Krupp breech and used brass cartridge cases for all calibres) and the hydraulic rammer which rammed the shell and cartridge into the gun. Loaded – ready – the loaded gun was run back on its mounting with the breech end over the well between the two side frames of the carriage. Aim – the piece was raised to the required elevation which, for the heavy siege guns, was a relatively high angle.
Yamada's forces were spread out in a series of outposts that were orientated around a main defensive position established at Sattelberg, an abandoned Lutheran mission situated atop a mountain that dominated the terrain about north-west of Finschhafen. The Japanese forces lacked transportation and the road network had not been fully developed. They were low on ammunition for all calibres of weapons, especially artillery, and the majority of stores had to be carried by combat troops, as local carriers had ceased working for the Japanese in response to Allied propaganda. Following the landing at Scarlet Beach, Yamada was ordered to launch an attack on the Australian forces in order to delay them so that further reinforcements could arrive from the 20th Division.
The 5.6×57mm (designated as the 5,6 × 57 by the C.I.P.) cartridge was created by Rheinisch-Westfälische Sprengstoffwerke (RWS) in Germany for hunting small deer such as roe deer, and for chamois. The calibre has a significant following among European sportsmen, and most European mass production riflemakers chamber several models of rifle for this cartridge. During the 1970-1990 period this cartridge was widely and successfully used in the Republic of Ireland for deer shooting, since security considerations at a period of Provisional Irish Republican Army violence had led to a ban on the civilian ownership of calibres larger than .224in. Some British small deer specialist hunters use the 5.6×57 mm with great success on roe deer, muntjac and Chinese water deer.
These 40 movements were tested for another 45 days, it was these 40 that became the Girard Perregaux Observatory Chronometers. Similarly in 1968, 1969 and 1970 Seiko had 226 wristwatches with its 4520 and 4580 Calibres certified as observatory chronometers. In both cases these observatory chronometers were then sold to the public for normal usage as wristwatches, and some examples may still be found today, although they are very rare. The Girard-Perregaux Calibre 32A movement that went into its Observatory Chronometers heralded a shift in watchmaking technology to higher frequency movements, and thus greater accuracy, that is followed today by watch manufacturers such as Seiko, Patek Philippe, Zenith, Audemars Piguet, Jaeger-LeCoultre, Chopard, Vacheron Constantin, Mathey-Tissot and such.
On 14 July 1915, Detective Sergeant Askew and Detective Constable Arthur Young went to serve a warrant on Gorges in his Mount Vernon, Hampstead, flat; the warrant was for “indulgence in illegal sexual practices” and the police officers were unarmed. The police had already visited the flat when Gorges was out, and had removed a revolver and 197 rounds of ammunition of two different calibres. They had also been told by someone who knew Gorges of his threats to shoot any policeman who attempted to lay a hand on him. When they eventually confronted Gorges they asked if they could talk to him privately; he at first agreed, but then pulled a second revolver and fired almost point blank at Detective Young.
In addition the mount had two heavy springs to counterbalance the barrel, as the entire barrel was mounted ahead of the pivots. It (the barrel), was 45 calibres long and had 28 grooves (rifling) twisting to the right - like the M/16's barrel. The breech block was also similar to the M/16: a semi- automatic horizontal-wedge that the gunner had to open manually to remove the case from the previous shot, but which closed automatically on insertion of a new round. Like late models of the M/16, the M/32 was equipped to receive gun- laying information from a central sight, and also had a device for automatically adjusting the timing of the fuses on the shells.
Additionally, the carronade was adopted by the Royal Navy in 1779, and the lower muzzle velocity of the round shot was intended to create many more of the deadly wooden splinters when hitting the structure of an enemy vessel; these in fact were often the main cause of casualties.The slow velocity also resulted in a larger hole or dent. It was much shorter and a third to a quarter of the weight of an equivalent long gun: for example, a 32-pounder carronade weighed less than a ton, but a 32-pounder long gun weighed over 3 tons. Carronades were manufactured in the usual naval gun calibres, but they were not counted in a ship of the line's rated number of guns.
Match Rifle shooting is a long-range target shooting discipline for civilian riflemen shot at 1,000 to 1,200 yards (approximately 914 to 1,097 meters), peculiar to the UK and several Commonwealth of Nations countries, and run according to rules set out by the National Rifle Association, UK. Elcho Shield is an example of such an annual fullbore Match Rifle competition. Match Rifle can be thought of as an extreme, experimental version of Target Rifle (TR). Whilst the same calibres are permitted (.308” Winchester / 7.62 x 51 mm NATO and .223” Remington / 5.56 x 45 mm NATO), Match Rifle starts at 1000 yards where TR finishes, and goes up to 1500 yards but 1200 yards is the usual maximum range in most competitions.
Georgios Averof in camouflage paint, RN Bombay Station, 1942 Four guns of 45 calibres (414 inches) bore produced by Elswick Ordnance CompanyDiGiulian were mounted in two twin turrets on the Greek cruiser Georgios Averof in 1910, instead of the 10-inch guns mounted on her sisters of the Pisa-class in Italian service. These were similar to the four Vickers 45-calibre export model guns used by Britain as railway artillery on the Western Front in World War I under the designation BL 9.2-inch gun Mark XIV. They fired the same 380-pound shell using the same 120-pound cordite charge as the British service Mk X gun, and it may be assumed that its performance was very similar.
The 28 cm Howitzer L/10 was designed in 1884 by the British Armstrong company. Armstrong had an Italian subsidiary which produced guns for the Italian Navy and Major Pompeo Grillo, a heavy artillery specialist was hired in April 1884 to help the construction of artillery at a new plant in Osaka. The description from Brassey's Naval Annual of 1892 reads "The howitzer was a 28-cm rifled breech- loader of cast iron, 9 calibres long made at Osaka, from the designs of guns made for the Italians by Sir W.G. Armstrong". The Italians produced the design in a number of different lengths and they were designated by their diameter and length in calibers 280/9, 280/10, 280/11, and 280/16.
Alternatively, cartridges can be singly loaded directly into the chamber. The TRG M10 has a side-folding and fully adjustable buttstock, featuring an aluminium middle chassis frame, side-folding buttstock, and a fore-end with the M-LOK rail interface system that allows for direct accessory attachment onto "negative space" (hollow slot) mounting points, ambidextrous controls, a manual safety that is located inside the trigger guard which is in front of the trigger, and uniquely designed tactical indicators which helps identify different modular components for different calibres, where every calibre-depending component is specially marked so users can recognise the calibre of each part visually or by touch. For example, for the .308 Winchester barrel and bolt are marked with single annual grove, whereas for the .
The de Bange system formed the obturation system for all subsequent screw breeches to the present day. Britain adopted the de Bange breech when it returned to breechloaders in the early 1880s after some initial experiments with the inferior "Armstrong cup" obturation system. Britain, France and the United States preferred screw breeches for most calibres, but the major drawback of the de Bange interrupted screw as first implemented was that only half of the circumference of the breech block could be threaded, and hence it needed to be fairly long to achieve safe locking of the breech, which required three separate motions to open after firing; rotate to unscrew, retract the screw and swing to the side. Loading required the 3 operations in reverse.
There are several variants made with mostly cosmetic differences, the only anomaly being the SSG-PIV using a 409 mm barrel with a 1:250 mm (1:10 inches) twist designed to handle heavy subsonic ammunition in conjunction with a suppressor. The bolt action uses rear-locking lugs (in common with the SMLE), rather than the more common front-locking lugs. This, and the fact that it is only produced in the 'short action' length, limits the chambering to non- magnum calibres, a legacy of a military weapon designed only to fire the 7.62×51mm NATO cartridge. It is essentially a target/police/military weapon, but with its caliber and inherent accuracy, it lends itself to hunting that requires longer distance shots.
The English army possessed about a dozen heavy guns used for sieges which played no part in the battle. The field artillery of both armies, of a variety of calibres from 3 to 20 pounds (1.4 to 9 kg), was immobile once positionedwhere wheeled carriages were provided the wheels were removed before firing. Usually the guns were allocated two or three to each regiment, to provide direct support, but for this battle Cromwell massed all of his field artillery in one group. The Scottish artillery was even less mobile than the English, and most of it played no part due to the way the battle developed, but a few of the lighter Scottish pieces, attached to individual regiments, saw action.
With three month worth of food for the 1200-man complement, and one month worth fresh water completed by a distillation device to desalinate seawater, she could stay at sea for 40 days. The main battery of Bretagne used 36-pounder long guns, the heaviest available calibre, instead of the more modern 30-pounder long gun on which other ships standardised their armament. The aft of the ship was round and featured gun ports, like on Napoléon on her successors. Although she carried 130 guns of various calibres, Bretagne featured no less than 180 gun ports; this allowed the crew to reinforce the artillery on one arc if needed and time permitting, such as before a shore bombardment, and fire up to 80 guns on one target.
SP Bofors in Holland, December 1944. 53rd (Welsh) Division was next engaged in the fighting in the Reichswald, (Operation Veritable). XXX Corps launched its attack at 05.00 on 8 February, and as the field and medium artillery concentrated on the enemy's batteries, command posts and communication centres, the divisional LAA regiments took part in the 'Pepperpot', in which guns and mortars of all calibres saturated the enemy positions in front of the assaulting infantry. By this stage of the war divisional LAA regiments had received quadruple 0.5-inch Browning machine guns on SP mountings (the M51 Quadmount) in place of a proportion of their Bofors guns, to improve their capability against 'snap' attacks by the new German jet fighter-bombers.
Between 1994 and 1997, there were at least thirty-six break-ins at Swedish and Danish Army installations; at least sixteen Bofors anti-tank missiles, ten machine guns, around three-hundred handguns, sixty-seven fully automatic rifles, two-hundred-and-five rifles of various calibres, hundreds of hand grenades and land mines, and seventeen kilograms of explosives plus detonators were stolen. Police believe the Bandidos or their support clubs were responsible for the majority of the thefts. The Hells Angels obtained Russian- and Yugoslavian-made rocket launchers as well as surplus machine guns and rifles from East European countries.The Mammoth Book of Bikers Arthur Veno (2007) The conflict saw the use of the Swedish AT4 eight times, and the Russian RPG-22 three times.
Stereoscopic image of the Great Krupp Building The German firm Krupp had a pavilion of artillery, which apparently had cost one million dollars to stage, including a coastal gun of 42 cm in bore (16.54 inches) and a length of 33 calibres (45.93 feet, 14 meters). A breech-loaded gun, it weighed 120.46 long tons (122.4 metric tons). According to the company's marketing: "It carried a charge projectile weighing from 2,200 to 2,500 pounds which, when driven by 900 pounds of brown powder, was claimed to be able to penetrate at 2,200 yards a wrought-iron plate three feet thick if placed at right angles."John Birkinbine (1893) "Prominent Features of the World's Columbian Exposition", Engineers and engineering, Volume 10, p.
While the first two lines to the north of Lisbon were designed to protect the Portuguese capital, this third line was aimed at protecting the possible evacuation of Portuguese and British soldiers, the latter commanded by Arthur Wellesley, 1st Duke of Wellington. The evacuation was planned to take place at the fort of São Julião da Barra but was not required due to the success of the most northerly of the lines in resisting French troops. At the time of the Portuguese Civil War (1828-1834), the fort had 14 artillery pieces of various calibres. It was rebuilt in 1853 and further restoration was carried out in 1868 but the fort was never again used and, like other coastal fortifications at the time, it eventually fell into disrepair.
On 12 October 2013, Mexican authorities captured alleged top Zetas operative Gerardo Jaramillo, alias "El Yanqui".Wells, Miriam. "Zetas' Top Guatemala Operative Captured in Mexico". "InSightCrime.org". 15 October 2013. Retrieved 30 July 2014. His arrest ultimately resulted in the discovery and seizure of a large Zetas weapons cache and supply stash, including "assault rifles, several grenade launchers, magazines, 2,000 rounds of ammunition of various calibres, bullet-proof vests and balaclavas". On 9 May 2014, one of the founding members, Galindo Mellado Cruz, and four other armed men were killed in a shootout after Mexican security forces raided Cruz's hideout in the city of Reynosa. On 3 March 2015, Mexican security forces arrested the last known leader of the remaining Zetas structure, Omar Treviño Morales (alias "Z-42") in a suburb in Monterrey, Nuevo León.
300px Protected in 1938 by then National Historic and Artistic Heritage Services, consolidation by small interventions performed in 1966 and 1973, a time when the island began to project itself as tourist resort. In 1971, the Archaeology Laboratory of the Federal University of Pernambuco held the fort prospecting in part, identified areas of the kitchen, the chapel, the rooms and lockers, and recovering various objects of personal use, guns and ammunition of various calibres. The Department of the Army began their reforms in the early 1980s, from the administration for the City of Itamaracá (1984). It is from this period date the involvement of ex-convict and craftsman José Amaro de Souza Filho with storage and maintenance freestanding monument by revenue from the sale of crafts place, a situation that lasted until 1992.
As a result, field artillery became more viable, and began to see more widespread use, often alongside the larger cannon intended for sieges. Better gunpowder, cast-iron projectiles (replacing stone), and the standardisation of calibres meant that even relatively light cannon could be deadly. In The Art of War, Niccolò Machiavelli observed that "It is true that the arquebuses and the small artillery do much more harm than the heavy artillery." This was the case at the Battle of Flodden, in 1513: the English field guns outfired the Scottish siege artillery, firing two or three times as many rounds.Sadler, p. 60. Despite the increased maneuverability, however, cannon were still the slowest component of the army: a heavy English cannon required 23 horses to transport, while a culverin needed nine.
During the Great War the company had a number of military contracts for sniper rifles and related equipment, but the decline in civilian sales post-war saw the company's fortunes fall. In 1920 Charles Jeffery died and his nephew F. Jeffery Pearce took over the company, in 1921 the Queen Victoria Street shop was closed and in 1927 the company moved to 9 Golden Square, Soho. The Second World War failed to generate much business for W.J. Jeffery & Co and the retracting British Empire after the war saw the sales of big game hunting rifles fall further. Despite this the company continued and in 1955 moved to 5b Pall Mall, London, their catalogue that year offered one sidelock and two boxlock double rifles along with P-14 bolt actioned rifles in three calibres.
In 2015, Stas played a substantial role in the introduction of the "Horological Smartwatch", a smartwatch design that uses a secondary analog dial rather than a screen for its display – giving the timepiece a more classic look than other such devices. The Horological Smartwatch product line included models for both the Frédérique Constant and Alpina watch brands, and used "MotionX" core technology licensed from the California-based company Fullpower Technologies. It was developed in a joint venture known as Manufacture Modules Technologies (MMT). In 2016, Aletta and Peter Stas sold their watch brands to Citizen, creating a high-tech collaboration in development of electronic, mechanical and hybrid calibres combining Frederique Constant’s high-end Manufacture capability with Citizen’s long history in revolutionary solar, radio and ultra-thin calibre innovations.
A Gepard firing at the German army's Hohwacht Bay training area (1987) The vehicle is based on the hull of the Leopard 1 tank with a large fully rotating turret carrying the armament—a pair of 35 mm Oerlikon KDA autocannons and the two radar dishes—a general search radar at the rear of the turret and the tracking radar, and a laser rangefinder, at the front between the guns. Each gun has a firing rate of 550 rounds/min. The guns are 90 calibres () long, with a muzzle velocity of (FAPDS—Frangible Armour Piercing Discarding Sabot rounds), giving an effective range of 5,500 m. The KDA autocannon can take two different ammunition types; the usual loading is a mix of 320 AA and 20 AP rounds per gun.
Halstead fired a shot across the Batavian ship's bow as a warning to surrender to such overwhelming odds, but the Batavian captain refused and opened fire on the British frigate. Although Argo made strenuous efforts to escape during the exchange of fire, Halstead's ship was both more accurate and effective, mounting 36 18-pounder cannon and 8 32-pounder carronades to the Batavian frigate's 12-pounder main battery supplemented with a number of cannon of lower calibres. In just 20 minutes, Phoenix had torn much of Argo's rigging, sails and masts and inflicted heavy casualties of eight killed and 28 wounded. With his ship damaged, Duncan's fleet in sight and Leopard not far behind Phoenix, the Batavian captain surrendered at 08:35, allowing Halstead to take possession of his vessel.
"157th Division. "Staff. General Order No. 234 "In transmitting to you with legitimate pride the thanks and congratulations of the General Garnier- Duplessis, allow me, my dear friends of all ranks, Americans and French, to thank you from the bottom of my heart as a chief and a soldier for the expression of gratitude for the glory which you have lent our good 157th Division. I had full confidence in you but you have surpassed my hopes. "During these nine days of hard fighting you have progressed nine kilometers through powerful organized defenses, taken nearly 600 prisoners, 15 guns of different calibres, 20 minenwerfers, and nearly 150 machine guns, secured an enormous amount of engineering material, an important supply of artillery ammunition, brought down by your fire three enemy aeroplanes.
In the Royal Navy, the switch to breech-loaders was finally made in 1879; as well as the significant advantages in terms of performance, opinion was swayed by an explosion on board caused by a gun being double-loaded, a problem which could only happen with a muzzle-loading gun.Roberts, J "Warships of Steel 1879–1889" in Gardiner Steam, Steel and Shellfire The calibre and weight of guns could only increase so far. The larger the gun, the slower it would be to load, the greater the stresses on the ship's hull, and the less the stability of the ship. The size of the gun peaked in the 1880s, with some of the heaviest calibres of gun ever used at sea. carried two 16.25-inch (413 mm) breech- loading guns, each weighing 110 tons—no British battleship would ever carry guns as large.
The barrel is interchangeable with other calibres; this can be done in the field in about 15 minutes. With the barrel clamped in a barrel vice, the barrel is removed from the action, and another one screwed into the action and tightened in place with a torque wrench. Newer versions of Accuracy International rifles including the AX, AT (Accuracy Tactical), and AXMC (AX Multi-Calibre) feature a switch-barrel system that allow the user to change out the barrel with only the use of a 4mm hex wrench, allowing field barrel changes in under a minute. The inherent accuracy of the rifle is due to the action being bolted with four screws and permanently bonded with epoxy material to an aluminium chassis which extends the entire length of the rifle stock, to which all major rifle components are in turn attached.
A 60-pounder battery firing in the open during the German Spring Offensive, 1918. Second Army HQ was sent to the Italian Front at the end of 1917, and Fourth Army took over the Ypres Salient, with 1/1st Welsh Hvy Bty transferring to 53rd HAG on 18 December. By now HAG allocations were becoming more fixed, and on 1 February 1918 the HAGs were converted into permanent RGA brigades, with 53rd becoming a 'Mixed' brigade of 60-pounders and batteries of various calibres of howitzers.Farndale, Western Front, Annex M. Second Army HQ resumed command of the Ypres sector (including 53rd (Mixed) Bde RGA), in March 1918 and was soon involved in the Battle of the Lys, the second phase of the German Spring Offensive that involved great loss of ground and rapid retreat for much of the artillery.
The gun designation "75/34" referred to a 75 mm bore diameter gun with a length equal to 34 calibres. However, the weight increase (which now topped at 26 tonne) and the difficulties in finding a suitable engine further hampered the start of mass production; in the end, it was decided that the prototype and the early production samples were to be equipped with a 330 HP SPA 8V diesel engine, later to be replaced by a 420 HP petrol engine. Only a few (between one and five depending on the source) pre- production models were completed before the Italian Armistice in September 1943, at which point they were taken over by the German Wehrmacht. A few were used in combat, under the German designation of Panzerkampfwagen P40 737(i), for example at Anzio; some, without engines, were used as static strongpoints.
The last surviving Schneider CA in the Musée des Blindés at Saumur To the modern eye, the tank is hardly recognizable as such and appears as an armoured steel box resting on top of a caterpillar tractor. It has no turret, and its inconspicuous main armament is a fortification 75 mm Blockhaus Schneider, placed in a barbette in the right front corner of the tank. The right side had been chosen because the gunner had to stand to the left of the barrel to operate the gun. The cannon type was developed from a 75 mm trench mortar that had been adapted to fire from a fixed fortification position by adding a recoil compensator and a gun shield; in this configuration it weighed 210 kilogrammes. This short-barrelled cannon had a length of just 9.5 calibres.
In 1925, the LeCoultre Calibre 7BF Duoplan was created in an effort to bring together miniaturisation and precision. The fashion of the period was for small wristwatches, however small calibres often suffered from a loss of reliability. Created by Henri Rodanet, the technical director of Etablissements Ed. Jaeger, the Duoplan was built on two levels – hence its name – enabling it to maintain a large-size balance. The Duoplan was also one of the first gem-set steel watches and, in 1929, its glass was replaced with sapphire crystal, a first in watchmaking. The Duoplan was ensured by Lloyd's of London with a special after-sales service, and a damaged movement could be replaced in a few minutes, leading London-based store owner Tyme to display in its shop window: “You won’t have time to finish your cigarette before your watch is repaired”.
It is important to note that the term "Lépine" can refer to both the calibre itself or a type of pocket watch with a flat, open-faced case in which the second wheel is placed in the axis of the winder shaft and the crown positioned at XII, in opposition to the savonete (or hunter-case) watch where the second wheel and winder shaft are placed on perpendicular axes and the crown at III. This design has been known within the watch industry as the Lépine style ever since. Lépine's work profoundly influenced all subsequent watchmaking, particularly Abraham Louis Breguet who used a modified version of the "calibre ponts" for his ultra slim watches. Indeed, except from the very start of his career the celebrated and extremely well known Breguet almost always used Lépine calibres and then modified them.
By 1917 it had been determined that standard rifle calibre cartridges were less satisfactory for balloon busting (shooting down observation balloons) than larger calibres carrying incendiary or tracer bullets. The French adapted the standard 11x59mmR Gras cartridge to fire from their Hotchkiss M1914 machine gun as an aircraft gun. Later the more reliable and more easily synchronised Vickers machine gun was chambered in the round, known as the Vickers aircraft machine gun and sometimes the "balloon buster", it fired the same cartridge with incendiary bullets and disintegrating belt link, the cartridge became known as the 11mm Vickers in British service. The Vickers aircraft machine gun and the 11mm Vickers was adopted by the allies as a standard anti-balloon armament and used by both the British and French in this role until the end of the war, as well as other allies such as Belgium and the United States of America.
However, soon after work was completed the fort and chapel were severely damaged by the earthquake of November 1, 1755, although many of the tiles have survived. A decade later work was carried out to expand the structure, beginning with the so-called New Battery. View of the fort from 1763 In 1802, after the brief War of the Oranges in 1801, there were 24 artillery pieces of various calibres: eight on the original battery, twelve on a new battery, and four on the terrace above the strong house. In the context of the Peninsular War (1808-1814) the Fort of São João das Maias was integrated into the third of three lines of defence known as the Lines of Torres Vedras, at the extremity of a wall and trench designated "Military Work No. 110" out of a total of 152 works in the three lines.
Vanguards starboard aft side, showing her rear 12-inch gun turret and anti-torpedo net booms, around 1914 These ships were the first to carry the new 50-calibre breech-loading (BL) Mark XI gun, which was 5 calibres longer and had a muzzle velocity about higher than the 45-calibre Mark X gun used in the earlier dreadnoughts.Friedman (2011), pp. 59, 62. They had a reputation for drooping at the muzzle, which was believed to have an adverse effect at long range, but testing at sea showed the muzzle droop to be within normal tolerances and the accuracy at long range to be satisfactory.Parkes (1990), pp. 504–05. The increased muzzle velocity of the Mark XI gun gave it a longer range over the Mark X gun as well as increasing the distance at which it could penetrate 12 inches of armour from using the same shell.
The size and weight meant that to be at all movable it would need to be supported on twin sets of railway tracks. In common with smaller railway guns, the only barrel movement on the mount itself would be elevation, traverse being managed by moving the weapon along a curved section of railway line. Krupp prepared plans for calibres of 70 cm, 80 cm, 85 cm, and 1 m. Nothing further happened until March 1936 when, during a visit to Essen, Adolf Hitler inquired as to the giant guns' feasibility. No definite commitment was given by Hitler, but design work began on an 80 cm model. The resulting plans were completed in early 1937 and approved. Fabrication of the first gun started in mid-1937. Technical complications in the forging of such massive pieces of steel made it apparent that the original completion date of early 1940 could not be met.
A HE shell had been introduced for the 6-pounder, but it was described as being largely useless—the calibre of the gun was simply too small to carry a useful load of explosive. This was not entirely accidental; British tank policy of the time suggested that different models of the same tank, carrying different specialised weapons, was a better solution to this problem than a single weapon that attempted to do all things. Experience with the US M3 75 mm gun suggested this thinking was wrong, that a single gun could be used in a "dual purpose" role against both tanks and softer targets. This led Vickers to begin development of a 75 mm weapon of 50 calibres in length, which would fire the same HE shell as the US gun, but with a higher propellant load that would make its anti-tank rounds more effective.
While the thinner shell wall and absence of a central tube allowed the shell to carry far more bullets, it had the disadvantage that the bursting charge separated the bullets from the shell casing by firing the case forward and at the same time slowing the bullets down as they were ejected through the base of the shell casing, rather than increasing their velocity. Britain adopted this solution for several smaller calibres (below 6-inch) but by World War I few if any such shells remained. The final shrapnel shell design, adopted in the 1880s, bore little similarity to Henry Shrapnel's original design other than its spherical bullets and time fuse. It used a much thinner forged steel shell case with a timer fuse in the nose and a tube running through the centre to convey the ignition flash to a gunpowder bursting charge in the shell base.
Mk I & MK II gun barrels The 10-inch gun was a standard "Woolwich" design (characterised by having a steel A tube with relatively few broad, rounded and shallow rifling grooves) developed in 1868, based on the successful Mk III 9-inch gun, itself based on the "Fraser" system. The Fraser system was an economy measure applied to the successful Armstrong design for heavy muzzle- loaders, which were expensive to produce. It retained the Armstrong steel barrel surrounded by wrought-iron coils under tension, but replaced the multiple thin wrought-iron coils shrunk around it by a single larger coil (10 inch Mark I) or 2 coils (Mark II); the trunnion ring was now welded to other coils; and it eliminated Armstrong's expensive forged breech-piece.Treatise on Construction of Service Ordnance 1877, page 92-93 The gun was rifled with 7 grooves, increasing from 1 turn in 100 calibres to 1 in 40.
Diagrams showing the progressive changes in the gun's construction The rifling was the Woolwich pattern of a relatively small number of broad, rounded shallow grooves : there were 6 grooves, increasing from 0 to 1 turn in 45 calibres (i.e. 405 inches). Mark I, introduced in 1865, incorporated the strong but expensive Armstrong method of a steel A tube surrounded by multiple thin wrought-iron coils which maintained the central A tube under compression,Holley states that Daniel Treadwell first patented the concept of a central steel tube kept under compression by wrought-iron coils.. and that Armstrong's assertion that he (Armstrong) first used a wrought-iron A-tube and hence did not infringe the patent, was disingenuous, as the main point in Treadwell's patent was the tension exerted by the wrought-iron coils, which Armstrong used in exactly the same fashion. Holley, Treatise on Ordnance and Armour, 1865, pages 863–870 and a forged steel breech-piece. 190 were made.
Hughes & Migos, p. 40 The fortress seemed at first sight to be well-armed, with 339 cannon in 1744, but this number concealed the fact that they consisted of at least eight different calibres, some made of brass and some of iron – which meant greatly differing levels of reliability – and they required many different types of spares and ammunition, adding to the garrison's logistical problems.Hughes & Migos, p. 38 Skinner and Tyrawley agreed that the most pressing threat was that of a combined land and sea assault focusing on the weakest part of the defences, the open ground between the South Front of the town and Europa Point at the end of the peninsula. However, they disagreed vehemently over where and how to construct the defences. Tyrawley put a great deal of energy into constructing new earthworks, batteries and a series of retrenched lines between the South Bastion and the New Mole, called the Prince of Wales Lines.
Africa, due to a prevalence of corrupt officials and loosely enforced trade regulations, is a region with extensive illicit arms activity. In a resolution to complement the Register with legally binding obligations, a Firearms Protocol was incorporated into the UN Convention on Transnational Organized Crime, which requires states to improve systems that control trafficked ammunition and firearms. The 1999 Report of the UN Panel of Governmental Experts on Small Arms provides a more refined and precise definition, which has become internationally accepted. This distinguishes between small arms (revolvers and self-loading pistols, rifles and carbines, submachine guns, assault rifles, and light machine guns), which are weapons designed for personal use, and light weapons (heavy machine guns, hand-held under-barrel and mounted grenade launchers, portable anti-aircraft guns, portable anti-tank guns, recoilless rifles, portable launchers of anti- aircraft missile systems, and mortars of calibres less than 100 mm), which are designed for use by several persons serving as a unit.
The major battles in which the 7th was engaged were of course Normandy, the Scheldt and the Rhineland. The fire program for the opening of the latter is reported to have been the largest in the West during the war: at 05:00 on 8 February 1945, 1,400 British and Canadian guns of all calibres opened fire at once in support of the British XXX Corps, consisting for the opening of the battle of four British divisions and the 2nd Canadian Infantry Division attacking east from Nijmegen into Germany. Included in the preliminary bombardment, which ended at 09:30, were 16 medium regiments (13 Royal Artillery and three Royal Canadian Artillery. This was followed at 10:00 by the 2½-hour barrage in support of XXX Corps infantry attacking into Germany. In the ten months in which the 7th Medium was in action it had 124 casualties, of which 35 were killed and 89 wounded (some of the latter returned to the unit on recovery).
After rest, the division returned on 24 August for a more successful attack on High Wood. The divisional artillery was incorporated into a corps fireplan, with CLVI Bde supporting 7th Division, while CLXII and CLXVI supported 14th (L) Division. The bombardment began at 03.45, CLXII Bde sweeping the previously-registered Wood Lane in enfilade from 05.45. Zero was at 06.45, when the 18-pdrs began a creeping barrage and the 4.5s lengthened range to bombard the Flers-Longueval road. From his OP near Longueval, Lt-Col Harris was able to send situation reports back to 33rd Divisional HQ, allowing the commander to deal quickly with situations as they arose. The attack was very successful for the division, with 100th Bde finally capturing Wood Trench.Macartney-Filgate, pp. 42–5.Miles, 1916, Vol II, pp. 197–202.Seton-Hutchinson, p. 21. German retaliation came on 25 August, when every battery position was bombarded throughout the day with shells of all calibres.

Through 1943 the U.S. 8th Air Force and German Luftwaffe entered a period of rapid evolution as both forces attempted to gain an advantage. Having lost too many fighters to the bombers' defensive guns, the Germans invested in a series of heavy weapons that allowed them to attack from outside the American guns' effective range. The addition of heavy cannons like the 30mm calibre MK 108, and even heavier Bordkanone autoloading weapons in 37mm and 50mm calibres on their Zerstörer heavy fighters, and the spring-1943 adoption of the Werfer-Granate 21 unguided rockets, gave the German single and twin-engined defensive fighters a degree of firepower never seen previously by Allied fliers. Meanwhile, the single- engine aircraft like specially equipped Fw 190As added armor to protect their pilots from Allied bombers' defensive fire, allowing them to approach to distances where their heavy weapons could be used with some chance of hitting the bombers.
Mannlicher–Schönauer (Civilian version) Mannlicher- Schönauer Mod. GK bolt action hunting rifle cambered for 7×64mm The early years of the 20th century saw what was fundamentally the same rifle being offered in various other, larger Mannlicher–Schönauer calibres including the 8×56mm Mannlicher–Schönauer Model 1908, the 9×56mm Mannlicher–Schönauer Model 1905 and the 9.5×57mm Mannlicher–Schönauer Model 1910, but none of these sold as well as the 1903 Model in 6.5mm. Legendary American writer Ernest Hemingway frequently used the rifle, and mentions it in some of his writings, most notably The Short Happy Life of Francis Macomber. WDM "Karamojo" Bell, a prominent elephant (ivory) hunter in Africa in the early 20th century, also used the rifle in its original 6.5×54 chambering with considerable success. The ability of the diminutive 6.5×54 cartridge to take the largest and most dangerous of the big game species, such as African elephant and Cape Buffalo, was due in the main to the high sectional density of the 6.5mm projectiles used in the rifle, although precise placing of the shot was imperative.
Although heavier than the Lewis, its closed bolt firing cycle made it much easier to synchronize to allow it to fire through aircraft propellers. The belt feed was enclosed right up to the gun's feed-way to inhibit effects from wind. Steel disintegrating- link ammunition belts were perfected in the UK by William de Courcy Prideaux in mid-war and became standard for aircraft guns thereafter. By 1917 it had been determined that standard rifle calibre cartridges were less satisfactory for shooting down observation balloons than larger calibres carrying incendiary or tracer bullets; the Vickers machine gun was chambered in the 11mm Vickers round, known as the Vickers aircraft machine gun and sometimes the "Balloon Buster", and was adopted by the Allies as a standard anti-balloon armament, used by both the British and French in this role until the end of the war.Frank C.

There were evolutions in the gun's fire control systems as well. The early versions (Compatto) utilised radars such the RTN-10X Orion (made by Selenia, now Selex); From the early 1980s there was a more powerful and flexible system, the RTN-30X (used with the Dardo-E CIWS system and known within Italian Navy as SPG-73), that was capable to manage both guns (40, 76, and 127 mm calibres) and missiles (Sea Sparrow-Aspide). This system came in service with the Italian Navy, on the cruiser Garibaldi (C551: the RTN-30X entered in service first with s, but the Dardo 40 mm turret were slaved to the smaller and older RTN-20X radars), but still with the twin 40 mm Dardo's turrets; while the first ship equipped with Dardo E and 76 mm Super Rapido was the upgraded s, later followed by the Durand de la Penne class. The 76/62 has also been used with countless other fire control systems, when not being used in the Italian fleet.
In 1951, the Manufacture released the Futurematic, the world's first 100% automatic watch, the calibre 497, Calibre 497 debuted with the Jaeger-LeCoultre Futurematic and was much more advanced than the earlier JLC 476 and JLC 481. It features a larger balance for improved accuracy and hacking seconds. One unique feature is a lock that holds the swinging weight in place when the mainspring is fully wound. It also features a special 6 hour power reserve, allowing the watch to immediately function when it is put on, rather than requiring it to be wound first. The Calibre 497 featured a power reserve indicator along with small seconds located at the unusual position of 3:00. Calibre 817 was used in the Jaeger- LeCoultre Futurematic and was a modification of the existing Calibre 497. Like that movement, it has a power reserve indicator at 9:00 and small seconds 3:00, but in Cal. 817 and Cal. 837 these are tiny round windows rather than being full subdials. Calibre 827 returned to the full subdial format, Calibres 817, 827, and 837 were produced from 1956 through 1958, with just 3,500 movements made.
The rifled gun, a Bofors 105 mm L74 with a barrel length of 62 calibres, was able to use the same ammunition as the British Royal Ordnance L7, and would be equipped with an autoloader allowing a rate of fire of one round every third second, also allowing the crew to be reduced to two; a gunner/driver and the commander (most designs of the era used a crew of four), with a single person being able to handle all functions of the tank from his ordinary position due to duplicate controls. This would of course only be used in emergencies, as the workload would be overwhelming, but apart from providing redundancy it also allowed the crew to shift tasks between them as situation required. The concept went through practical tests, that quickly revealed that a two-man crew would not be self-sufficient when considering the many tasks not directly related to handling the tank: in particular, routine maintenance, bivouacking, track-changes and reloading in field. While the last issue could have been solved by adding staff to the ammunition crews, it was decided that a third crew-member was needed.
