The armored train grinding its way forward is a symbol as much as it is a mechanic, and it's of a piece with the hacked-together Howell Automatic Rifle with its absurd side-mounted gunsights, or the Mark V tank whose cannon turrets are obstructed by its massive treaded nose.

"In prepared testimony released on the eve of his appearance Thursday before the Senate Intelligence Committee, former FBI director James B. Comey placed President Trump in the gunsights of a federal criminal investigation, laying out evidence sufficient for a case of obstruction of justice," Philip Allen Lacovara — who served as counsel to Watergate special prosecutors Archibald Cox and Leon Jaworski — wrote in an op-ed published in The Washington Post.

Ferranti's factory on Ferry Road was built to make electronics for aircraft, including gyro-based gunsights for the Supermarine Spitfire.

He worked for forty years at Ferranti Scotland in Edinburgh, half of those years as general managerFlightglobal June 1981 from 1968; the company had 8,000 employees. He joined Ferranti in 1947. The company had established itself in Edinburgh during World War II to make gyroscopic gunsights (gyro gunsights). Projects he oversaw included the Ferranti Laser Target Marker (LTM or FLTM) and the Seaspray radar, and airborne interception radars.

British gunsights, catapult spools and other items were installed.Jackson 1968, pp. 40–42. After attempts to fit British radio sets, it was decided to use the superior American equipment.Green, Swanborough and Brown 1977, p. 68.

R. Wallace Clarke 1994 British Aircraft Armament Volume 2: RAF Guns and Gunsights from 1914 To The Present Day. ("Wallace Clarke") Page 42. In addition, there were trials of the Brock bullet that was used against ZeppelinsPRO AIR 20/495 (this ammunition was also trialled elsewhere, including at Kingsnorth in 1916.PRO AIR 1/658/17/122/587) It was during this period that Hill's interest in the design of gunsights began. A sight described as the ‘Hill’ sight was used in accuracy trials of the COW gun fired from an Airco DH.10 aeroplane.

Most Soviet fighters did not even have effective gunsights and their pilots, some cases in the early weeks, were forced to draw one on the windscreen by hand: "In the early days, incredible as it may seem, there was no reason for you to feel fear if the Russian fighter was behind you. With their hand-painted gunsights they couldn't pull the lead properly (deflection shooting) or hit you." Hartmann also considered the Bell P-39 Airacobra, the Curtiss P-40 Warhawk, and the Hawker Hurricane to be inferior to the Focke-Wulf Fw 190 and Bf 109, although they did provide the Soviets with valuable gunsight technology. Hartmann said the German pilots themselves still learned from their enemy.

USAFHRA Document 00103281 About a year later, JB-2s were tested as aerial targets for experimental infrared gunsights at Eglin.USAFHRA Document 00425257 The Navy version was featured in the movie The Flying Missile (1951), including submarine launches. The movie shows the missile being launched from a trolley with four JATO bottles.

The tailwheel was now fixed. Early Hurricanes lacked armour or self- sealing tanks. They used "ring and bead" gunsights, with the ring being mounted above the instrument panel and the bead mounted on a post above the engine cowling. The standard GM2 reflector gunsight was introduced in mid-1939, although many Hurricanes retained the "bead".

Stanaway 1998, p. 9. After the first few engagements, the Dutch halved the fuel and ammo load in the wing, which allowed their Buffalos (and their Hurricanes) to stay with the Oscars in turns. In February 1942 they received new model gunsights. Around the same time the Dutch started to use tracer ammunition as well.

Their gunsights, however, were limited to +15° until super-elevating prisms were installed by 1916 to allow full elevation. They fired projectiles, some more than those of the 12-inch Mark XI, at a muzzle velocity of at a rate of two rounds per minute.Friedman 2011, pp. 49–52 The ships carried 80–100 shells per gun.

ADM 186/216 The Sight Manual, 1916, p. 108 Despite this, the range dials on the gunsights at the time of construction were graduated to 15 degrees;ADM 186/216 The Sight Manual, 1916, p. 23 super-elevating cams and prisms to allow the full elevation of the guns to be used were issued some time after the Battle of Jutland.

Edinburgh's Telford College (tertiary) was at Crewe Toll, but has moved to a site at Granton. Fettes College (private, secondary) is close by. A major aerospace facility is situated in the area, the Leonardo S.p.A. facility that dates to a 1943 Ferranti factory originally set up to produce gyro gunsights for the Supermarine Spitfire that later became a major radar development site.

A trick of disaffected sailors was to remove gunsights and throw them overboard, and indeed this happened. Hall instructed the master at arms to look out for two sailors who had previously been friends but who now avoided each other. He took one, told him that the other had confessed they had removed the sights, and the sailor duly confessed. Behaviour on board improved.

F-16s flew escort/Wild Weasel missions escorting them and striking pre-planned targets. The 138th Fighter Squadron (174th TFW, New York ANG) used 24 F/A-16s equipped with a 30 mm gunpod, the GPU-5/A 'Pave Claw', a four-barreled derivative of the A-10 Thunderbolt's GAU-8 Avenger, but this proved a failure owing to excess vibration and inadequate gunsights.

The company also produced photographic lenses (1883), spectacle lenses (1889), microtomes (1890), binoculars and telescopes (1893). The firm was incorporated as "Bausch and Lomb Optical Company, Inc.," in 1908, the year Bausch's long-time partner died. Bausch's company did very well during the First World War as the war created a demand for binocular telescopes, range-finders, gunsights, searchlight mirrors, periscopes and torpedo tube sights.

Winsloe boarded Bedford again on the morning of the 23rd and found her partially flooded and with waves breaking over her quarterdeck. As the weather began to improve he ordered that her upper deck guns and their equipment be salvaged, despite the waist-deep water. The sailors were able recover nine 12-pounder guns, the ship's radio, searchlights, radio and gunsights that day.McBride, K.D., pp.

For instance, if this same target measures in the sight then the range is 500 metres.Warlow, p. 87 Another unit which is sometimes used on gunsights is the minute of arc (MOA). The distances corresponding to minutes of arc are not exact numbers in the metric system as they are with milliradians; however, there is a convenient approximate whole number correspondence in imperial units.

The French government sent aircraft to Republican forces in Spain, but they were obsolete by the standards of 1936. They were mainly Potez 540 bombers and Dewoitine D.372 fighters. The slow Potez 540 rarely survived three months of air missions, flying at 160 knots against enemy fighters flying at more than 250 knots. Few of the fighters proved to be airworthy, and they were delivered intentionally without guns or gunsights.

The flat portion of the deck armour was thick and thick where it sloped down to the sides of the ship. The conning tower was protected by 14 inches of armour. Asahi, like all the other Japanese battleships of the time, was fitted with four Barr and Stroud FA3 coincidence rangefinders that had an effective range of . The ships were also fitted with 24-power magnification telescopic gunsights.

However, they still lacked machine-guns, gunsights, ammunition stowage and many smaller other fittings and therefore were only usable for driver training; gunnery training was postponed. Most of the training took place at or near The Hague. In April the commander of the Cavalry Depot concluded that under these conditions at best a single platoon could be ready on 1 July and all four no earlier than 1 September. During April the remaining armoured cars were delivered, again incomplete.

Many pilots found themselves on the tail of an enemy aircraft, but too close to fire short-range Falcons or Sidewinders. Although by 1965 USAF F-4Cs began carrying SUU-16 external gunpods containing a 20 mm (.79 in) M61A1 Vulcan Gatling cannon, USAF cockpits were not equipped with lead-computing gunsights until the introduction of the SUU-23, virtually assuring a miss in a maneuvering fight. Some Marine Corps aircraft carried two pods for strafing.

Despite the T50 turret's shortcomings, it remained in service with all of the M113A1 APCs for over 30 years. A number of minor modifications were made to improve the turret's performance, but it was never considered genuinely satisfactory. For instance, the turret lacked predictive gunsights and had no integral night vision capabilities. An improved variant of the turret was developed during 1990 and early 1991; this design sought to address problems with the weapons mounting, gunsight, ammunition feed system.

After evacuation the survivors of 65th Fd Rgt assembled at Oxford and then moved to Gloucester, then to a camp at Cheltenham Racecourse, and later arrived at Castleford in Yorkshire. Replacement guns, modern 25-pounders, began to arrive on 18 July, but there were acute shortages of gunsights and of small arms.Farndale, Years of Defeat, p. 102. In October 44th (HC) Division returned to invasion-threatened South East England with XII Corps.Collier, Maps 5, 6, 17, 20.

On December 11, Japanese warships approached the Island. Cdr. Cunningham ordered the Marine commander, Major Devereux, to hold their fire until the ships were in easy range. The small U.S. force on the island repulsed the initial landing attempt, but they were in serious need of additional supplies and support – including gunsights, spare parts and fire-control radar – which Cunningham had requested earlier from the Commandant, 14th Naval District. But no reinforcements were to come by the attack.

It was founded as a partnership in 1880 by Worcester Reed Warner (1846–1929) and Ambrose Swasey (1846–1937). The company was best known for two general types of products: astronomical telescopes and turret lathes. It also did a large amount of instrument work, such as equipment for astronomical observatories and military instruments (rangefinders, optical gunsights, etc.). The themes that united these various lines of business were the crafts of toolmaking and instrument-making, which have often overlapped technologically.

The Ferranti Gyro Sight Mk I. The pilot/gunner had to look into the narrow field folded prismatic telescopic sight at the top of the device, a drawback corrected in the later Mark II. After tests with two experimental gyro gunsights which had begun in 1939, the first production gyro gunsight was the British Mark I Gyro Sight, developed at Farnborough in 1941. To save time in development the sight was based on the already existing type G prismatic sight, basically a telescopic gun sight folded into a shorter length by a series of prisms.Axis History Forum – RAF Fixed and Free-mounted Reflector Gunsights Prototypes were tested in a Supermarine Spitfire and the turret of a Boulton Paul Defiant in the early part of that year. With the successful conclusion of these tests the sight was put into production by Ferranti, the first limited-production versions being available by the spring of 1941, with the sights being first used operationally against Luftwaffe raids on Britain in July the same year.

Accurately aligned laser pointers are used as laser gunsights to aim a firearm. Some militaries use lasers to mark targets at night for aircraft. This is done to ensure that "friendly" and "enemy" targets are not mistaken. A friendly target may wear an IR emitting device that is only visible to those utilizing night vision (such as pilots.) To pinpoint the exact location of an enemy combatant, they would simply illuminate the target with a laser beam detectable by the attacking aircraft.

The American bombers flew at altitudes in excess of , and lacking a super-charger, the Fw 190s struggled to reach altitudes even with considerable warning from American radio/signals traffic. At that altitude, Fw 190A-2s had only slight speed advantages over the B-17. The Revi gunsights were set for fighter, not anti-bomber combat, and set for a range of . The large bombers loomed in quickly long before the German fighters had reached effective range encouraging premature firing.

The Japanese recorded 407 casualties during the first attempt. The Japanese force withdrew without landing, suffering their first setback of the war against the Americans. After the initial raid was fought off, American news media reported that, when queried about reinforcement and resupply, Commander Cunningham was reported to have quipped, "Send us more Japs!" In fact, Cunningham sent a long list of critical equipment—including gunsights, spare parts, and fire-control radar—to his immediate superior: Commandant, 14th Naval District.

In the early 2000s, Type 79s still in service were retrofitted with railed fore- ends to equip them with tactical accessories like gunsights and new muzzle brake devices. This was first seen with the Guangzhou Public Security Police. Other police forces that adopted the modernized Type 79s included the Shenzhen, Dongguan and Panyu Public Security Police forces. There are plans to replace the Type 79 in service with Chinese law enforcement agencies with the JH16-1, which was introduced in 2017 and chambered in 9x19mm.

With S/Sgt Kuhn covering him against possible defenders, First Sergeant Lomell went into the battery and set off silent thermite grenades in the mechanisms of two guns. Because the thermite grenades melted their gears in a moment, they effectively disabled them. After bashing in a third gun's gunsights, Lomell went back for more grenades. The official U.S. Army account of the episode reported that members of E Company "finished off the job" while Lomell was retrieving more thermite grenades from other members of his own company.

In July 2011, two Mark 50 eight-cell rocket launcher mounts were added to the port and starboard bow. In May 2012, an original SOA Radar mast (obtained on loan from PT Boats Inc. of Germantown, Tennessee) was installed along with an appropriately sized radar dome, signal generator and waveguide. Simultaneously, the 40mm Bofors cannon mount was improved with the addition of an ammunition clip holder/loader handrail to the rear of the mount, along with adjustable seats and authentic aerial spider type gunsights.

"The plane", noted Golodnikov, "had extremely powerful weapons: four 20 mm guns and two machine guns. Soon, however, the Germans started evading frontal attack against our "Cobras". We had a 37 mm gun, so no engine would save you, and one hit was enough to kill you." A Soviet post-war assessment of a captured Fw 190 D-9 found that the Lavochkin La-5 was a superior fighter in a mock dogfight, although the German machine was praised for the high quality of its windshield, gunsights, electrical equipment and stability as a gun platform.

Parish house Following her son's death, Elizabeth Colt commissioned the Church of the Good Shepherd in 1896 as a monument to his life. Built in High Victorian Gothic style, architectural features include a variety of gun parts, such as bullet molds, gunsights and cylinders. This unusual characteristic earns the building the title of likely being the only church in the world with a gun motif. When Elizabeth Colt died in 1904, she willed the majority of her estate, Armsmear, to the City of Hartford for use as a public park.

Post-war models added a small radar to automate the range measurement; these are known as radar gunsights. Gyro sights usually contained more than one reticle to assist in proper aiming: a fixed one, often just a dot, signifying the direction the guns are pointing, a moving one showing the corrected aiming point, and a ring to match to a target plane's known wingspan. A particularly advanced model, the K-14 found in the North American P-51 Mustang, had separate projectors and displays for air and ground attacks.

Though these may be considered the most significant, many other items were also transported, including designs for rockets, superchargers, gyroscopic gunsights, submarine detection devices, self-sealing fuel tanks and plastic explosives. The American Congress had many proponents of neutrality for the USA and so there were further barriers to co- operation. Tizard decided that the most productive approach would be simply to give the information and use America's productive capacity. Neither Winston Churchill nor the radar pioneer, Robert Watson-Watt, were initially in agreement with these tactics for the mission.

The Prussian Dreyse needle gun Prussian infantry were equipped with the Dreyse needle gun, a bolt-action rifle which could be fired faster than the muzzle- loading Lorenz rifles of the Austrian army. In the Franco-Austrian War of 1859, French troops took advantage of poorly trained enemies who didn't readjust their gunsights as they got closer -- thus firing too high at close range. By rapidly closing the range, French troops came to close quarters with an advantage over the Austrian infantry. After the war, the Austrians adopted the same methods, which they termed the ("shock tactics").

Example of a catadioptric lens that uses rear surfaced "mangin mirrors" (Minolta RF Rokkor-X 250mm f/5.6) Mangin mirrors are used in illumination and image forming optics such as search lights, headlamps, aircraft gunsights and head-mounted displays. Many Catadioptric telescopes use negative lenses with a reflective coating on the back surface that are referred to as "Mangin mirrors", although they are not single-element objectives like the original Mangin, and some, like the Hamiltonian telescope, predate the Mangin's invention by over 60 years.\- Vladimir Sacek, telescope- optics.net, Notes on AMATEUR TELESCOPE OPTICS, CATADIOPTRIC TELESCOPES, 10.2.

Development of the ZPU-2 and ZPU-4 began in 1945, with development of the ZPU-1 starting in 1947. All three were accepted into service in 1949. Improved optical predicting gunsights were developed for the system in the 1950s. All weapons in the ZPU series have air-cooled quick- change barrels and can fire a variety of ammunition including API (B32), API (BS41), API-T (BZT) and I-T (ZP) projectiles. Each barrel has a maximum rate of fire of around 600 rounds per minute, though this is practically limited to about 150 rounds per minute.

Morey studied chemistry at the University of Minnesota with a bachelor's degree in 1909 and was a member of the Geophysical Laboratory of Carnegie Institution in Washington, DC from 1912 until his retirement in 1953. He was Acting Director of the Laboratory from 1952 to 1953 before Philip H. Abelson replaced him.Biography at the Carnegie Institution He focused on experimental investigations of phase equilibria and thermodynamics of silicate melts with volatile components, such as water and carbon dioxide. In both WW I and WW II, Morey, as an expert on glass, was involved in the Laboratory's optical glassmaking projects for military equipment, such as rangefinders and gunsights.

50 caliber (12.7 mm) machine guns, which were range adjusted by radar gunsights. If coming in at higher altitude the advantage of engaging or not went to the MiG. Once in a level flight dogfight, both swept-wing designs attained comparable maximum speeds of around . The MiG climbed faster, but the Sabre turned and dived better. In the summer and autumn of 1951, the outnumbered Sabres of the USAF's 4th Fighter Interceptor Wing—only 44 at one point—continued seeking battle in MiG Alley, where the Yalu River marks the Chinese border, against Chinese and North Korean air forces capable of deploying some 500 aircraft.

XI, Wiesbaden, Germany, 1945, pp. 66–67. Even though the various gunsights fitted to the Sherman had fewer magnification settings than those fitted to German tanks, their gunners were able to use a secondary periscope that featured a far larger field of view than their German counterparts. T4 High-Velocity Armor Piercing (HVAP) ammunition became available in September 1944 for the 76 mm gun. The projectile contained a tungsten penetrator surrounded by a lightweight aluminum body and ballistic windshield, which gave it a higher velocity and more penetrating power. The increased penetration of HVAP allowed the 76 mm gun to match the Panther's 7.5 cm KwK 42 APCR shot.

The 22nd had entered the fighting with fewer than thirty working tanks, and left with a company of tanks. The Romanian 1st Armored Division, attached to the 48th Panzer Corps, engaged the Soviet 26th Tank Corps after having lost communications with their German corps commanders, and were defeated by 20 November. As the Soviets continued to advance southwards, many Soviet tank crews began to suffer from the worsening blizzard, which affected men and equipment, and blocked gunsights. It was not uncommon for tanks to lose traction on the ground, and for a crew member to have an arm broken as he was thrown around inside the hull.

The group operated a climate-controlled hangar to test aircraft in arctic cold conditions to desert and subtropical humid heat. In the spring of 1949 launched Republic-Ford JB-2 missiles from underneath the wings of B-36 Peacemaker aircraft. About a year later, JB-2s were tested as aerial targets for experimental infrared gunsights, being launched from Wagner Field (Formerly: Eglin Air Force Auxiliary Field #1) as part of project MX-544. The fourth F-82B Twin Mustang (44-65163) was fitted with retractable pylons under the outer wings capable of mounting 10 High-Velocity Air Rockets (HVAR) each, which folded into the wing undersurface when not in use.

The wings grew in length at shorter distances to indicate the target was closer, as does the aircraft's wings when seen visually. A "shoot now" range indicator is often supplied as well, typically consisting of two short vertical lines centered on either side of the middle of the display. To make an interception, the pilot guides his aircraft until the blip is centered, then approaches until the "wings" fill the area between the range markers. This display recreated a system commonly used on gunsights, where the pilot would dial in a target's wingspan and then fire when the wings filled the area inside a circle in their sight.

Hill's main contribution was in working with gunsights and armament trials in which he could bring to bear his mathematical abilities. In accordance with civil service practice at the time discoveries made by civil servants could be patented by them. He was awarded several secret patentsUK patent numbers 404362, 336030, 404719, 452915, 396108 and 1923 patents 20308 and 31614 and 1935 patent 15885 relating to reflector gunsight improvements, including the ability to adjust for range. He also patented the use of monochromatic light in gun sights (the 1920s equivalent of the modern red dot sight) and was awarded patents for improvements to machine gun muzzle locks and machine gun synchronisation gear.

Hahn was a Boy Scout fascinated by chemistry, and spent years conducting amateur chemistry experiments, which sometimes caused small explosions and other mishaps. He was inspired in part by reading The Golden Book of Chemistry Experiments, and tried to collect samples of every element in the periodic table, including the radioactive ones. He later received a merit badge in Atomic Energy and became fascinated with the idea of creating a breeder reactor in his home. Hahn diligently amassed radioactive material by collecting small amounts from household products, such as americium from smoke detectors, thorium from camping lantern mantles, radium from clocks, and tritium from gunsights.

The final payment of $83.3 million (£42.5 million), due on December 31, 2006 (repayment having been deferred in the allowed five years and during a sixth year not allowed), was made on December 29, 2006 (the last working day of the year). After this final payment Britain's Economic Secretary to the Treasury formally thanked the U.S. for its wartime support. Tacit repayment of Lend-Lease by the British was made in the form of several valuable technologies, including those related to radar, sonar, jet engines, antitank weaponry, rockets, superchargers, gyroscopic gunsights, submarine detection, self-sealing fuel tanks, and plastic explosives as well as the British contribution to the Manhattan Project.

Directors I to III controlled the gun mounting through "follow the pointer" control and aimed at aircraft using eye shooting techniques through a simple ring sight.Raven and Roberts, British Battleships of World War Two, p429 These directors began to appear on Royal Navy cruisers, battleships and aircraft carriers in 1930. They were universally fitted, one per pom-pom gun mounting, by the late 1930s.Raven and Roberts, British Battleships of World War Two, p159 Most destroyers and smaller ships that carried 2-pounder guns continued to rely on aiming the guns with the on-mount gunsights due to the lack of space on these ships to site a director.

Simple systems, known as lead computing sights also made their appearance inside aircraft late in the war as gyro gunsights. These devices used a gyroscope to measure turn rates, and moved the gunsight's aim-point to take this into account, with the aim point presented through a reflector sight. The only manual "input" to the sight was the target distance, which was typically handled by dialing in the size of the target's wing span at some known range. Small radar units were added in the post-war period to automate even this input, but it was some time before they were fast enough to make the pilots completely happy with them.

First World War era Zeiss binoculars An exchange of rubber for optical glass was proposed by Britain and Germany during the First World War. Optical glass was vital to the warfare of this era for binoculars and gunsights and rubber was needed for tyres and communications cables. Britain had sourced the majority of its pre-war optical glass from the German company of Carl Zeiss AG and by early 1915 was suffering from a shortage. Germany, with its sea trade blockaded by allied forces, was unable to import natural rubber and found it could not create enough high-quality synthetic rubber to replace it.

I-8 left Brest on 5 October, with a cargo of German equipment, such as: machine guns, bomb sights, a Daimler-Benz torpedo boat engine, marine chronometers, radars, sonar equipment, anti-aircraft gunsights, electric torpedoes, and penicillin. The submarine also transported Rear Admiral Yokoi, naval attaché to Berlin since 1940; Captain Hosoya, naval attaché to France since December 1939; three German officers and four radar and hydrophone technicians. I-8 hit rough seas in the South Atlantic off the Cape of Good Hope, which delayed her arrival in Singapore. She radioed her position to Germany, but the message was intercepted by the Allies, prompting an attack by anti-submarine aircraft, which failed.

Today, engraved lines or embedded fibers may be replaced by a computer-generated image superimposed on a screen or eyepiece. Both terms may be used to describe any set of lines used for optical measurement, but in modern use reticle is most commonly used for gunsights and such, while graticule is more widely used for the oscilloscope display, microscope slides, and similar roles. Reticle accessory (PD-8) used in sniper rifles There are many variations of reticles; this article concerns itself mainly with a simple reticle: crosshairs. Crosshairs are most commonly represented as intersecting lines in the shape of a cross, "+", though many variations exist, including dots, posts, circles, scales, chevrons, or a combination of these.

Once pilots learned that the best method of achieving a kill was to aim the aircraft rather than the gun, the machine gun was fixed in the forward-facing centre mount, although this was initially banned by higher authorities until a clip which fixed the gun in place, but could be released if required, was approved.Goulding 1986, p. 11. A clip was devised by Major Lanoe Hawker, who also improved the gunsights and added a ring sight and an "aiming off model" that helped the gunner allow for leading a target.Guttman 2009, p. 31 The majority of DH.2s were powered by the 100 hp (75 kW) Gnôme Monosoupape rotary engine; however, later models received the 110 hp (82 kW) Le Rhône 9J engine instead.

Ajaxs forward main-gun turrets in 1918 The King George V class was equipped with ten 45-calibre breech-loading (BL) 13.5-inch Mark V gun in five hydraulically powered, centreline, twin-gun turrets, designated 'A', 'B', 'Q', 'X' and 'Y' from front to rear. The guns had a maximum elevation of +20° which gave them a range of . Their gunsights, however, were limited to +15° until super-elevating prisms were installed by 1916 to allow full elevation. In contrast to the Orions, the loading machinery of these turrets was modified to accommodate longer and heavier projectiles, some more than those of the Orions, at a muzzle velocity of about at a rate of two rounds per minute.Friedman 2011, pp.

The combination would prove deadly over the skies of Vietnam against aircraft such as the F-4 Phantom whose pilots lamented that guns and radar gunsights had been omitted as obsolescent.Davies, Peter. USN F-4 Phantom II Vs VPAF MiG-17: Vietnam 1965-72. London: Osprey, 2009. . The second prototype variant, "SP-2" (dubbed "Fresco A" by NATO), was an interceptor equipped with a radar. Soon a number of MiG-17P ("Fresco B") all-weather fighters were produced with the Izumrud radar and front air intake modifications. In early 1953 the MiG-17F day fighter entered production. The "F" indicated it was fitted with the VK-1F engine with an afterburner by modifying the rear fuselage with a new convergent-divergent nozzle and fuel system.

MB.151 in 1939 Upon evaluation, early deliveries were deemed unsuitable for combat operations, principally due to issues with the tailplane; thus, plans were laid for the first 157 production fighters to be stored awaiting modification, while additional production examples were built with the correction made. Furthermore, the type was initially confined to performing training duties alone; prior to the outbreak of the Second World War, only a single squadron, allocated to the 1st Escadre de Chasse, received the type. Upon the eve of the conflict, around 249 aircraft had been manufactured; of these, roughly 123 aircraft had been accepted by the Armée de l'Air. However, few of these were considered to be flyable, the majority missing their gunsights and propellers.Cristesco 1967, p. 6.

M2 gun director 1932 in production Coverall for female war workers Sperry Corporation (1910−1986) was a major American equipment and electronics company whose existence spanned more than seven decades of the 20th century. Through a series of mergers it exists today as a part of Unisys, while some other of its former divisions became part of Honeywell, Lockheed Martin, Raytheon Technologies, and Northrop Grumman. The company is best known as the developer of the artificial horizon and a wide variety of other gyroscope-based aviation instruments like autopilots, bombsights, analog ballistics computers and gyro gunsights. In the post-WWII era they branched out into electronics, both aviation related, and later, computers.

216SCFC, Get Acquainted With Forestry Tools Article Hand or sighting compasses include instruments with simple notch-and-post alignment ("gunsights"), prismatic sights, direct or lensatic sights,Johnson, Mark, The Ultimate Desert Handbook: A Manual for Desert Hikers, Campers, and Travelers, McGraw-Hill Professional (2003), , 9780071393034, p. 134: A direct- sighting compass uses a magnifying viewfinder mounted in the compass body to directly view a degreed dial and superimposed indicator line; it therefore differs from a lensatic sight (which uses a simple magnifying lens on a folding arm positioned over the dial), or a prismatic sight (which uses a magnifying optical prism). and mirror/vee (reflected-image) sights. With the additional precision offered by the sighting arrangement, and depending upon construction, sighting compasses provide increased accuracy when measuring precise bearings to an objective.

During World War II, Ferranti became a major supplier of electronics, fuzes, valves, and was, through development of the Identification Friend or Foe (IFF) system, heavily involved in the early development of radar in the United Kingdom. In the post- war era this became a large segment of the company, with various branches supplying radar sets, avionics and other military electronics, both in the UK and the various international offices. Spitfire gyro gunsight In 1943 Ferranti opened a factory at Crewe Toll in Edinburgh to manufacture gyro gunsights for the Spitfire aircraft. After the war they set up Ferranti Research to complement this business which grew to employ 8,000 staff in 8 locations, becoming the birthplace of the Scottish electronics industry,Hansard and a major contributor to company profitability.

The Lion-class ships mounted eight BL 13.5-inch Mark V guns in four twin hydraulically powered gun turrets, designated 'A', 'B', 'Q' and 'Y'. Unlike the two previous classes of battlecruiser in the Royal Navy, which had turrets fore, aft and on each side of the ship, the Lion-class ships had their main armament mounted in a single line from front to rear, with 'B' turret superfiring over 'A' turret, 'Q' turret mounted amidships, and 'Y' turret aft. The guns had an elevation range from −3° to +20°; their gunsights were limited to +15° until super-elevating prisms were installed before the Battle of Jutland in May 1916 to allow full elevation. They fired projectiles at a muzzle velocity of ; at +20° elevation, they had a range of .

Margaret Dady, Women's War: Life in the Auxiliary Territorial Service (1986) Over the six-year period of the War, about 500 ATS personnel were trained to operate the Cinetheodolite, with the highest number being in 1943–44, when 305 ATS were in active service using this equipment.Margaret Lang, Senior Commander K.T Staff, School of A. A. Artillery, Manorbier in The Kine Gazette, December 1945. Printed by E.H. Leach, South Parade, Tenby One application of this specialist camera was in gunnery practice, where a pair of Cinetheodolites a known distance apart filmed the shell bursts from anti- aircraft artillery against target drones towed by an aircraft. By comparing the filmed location of the shells' detonation and the target, accurate calculations of their relative position could be made that would reveal any systematic error in the gunsights.

In addition to the Vietnam War, he has also been through the Iran hostage crisis and the Gulf War, plus a number of missions in the Soviet Union, and claims to have "had Abu Nidal's head in my gunsights", but never got the green light allowing him to kill the man (Clear and Present Danger). He first enters the Jack Ryan universe in Without Remorse, which also features police officer Emmet Ryan and his son Jack. Although he does not appear in Patriot Games, it is later revealed that he was the CIA's liaison with a French black ops unit involved in the campaign against the ULA. He also does not appear in Red Rabbit, but is mentioned as giving advice to trainees at The Farm, the CIA training facility.

In 1900 Kennedy was asked by The Admiralty to serve as a member of the Belleville Boiler Committee to investigate the installation of French designed Belleville boilers on Diadem class cruisers. This was the first in a long line of Admiralty commissions that he undertook which included work behind the front lines in France during the First World War. There followed several more admiralty appointments, serving on the Machine Design Committee from 1900 to 1906, the Ordnance Board in 1909 and on the government committee for wireless telegraphy in 1913. During the First World War his skills were in great demand and he served on many committees including the Panel of the Munitions Inventions Department; as chairman of the Committee on Gunsights and Rangefinders; Vice-Chairman of the Committee on Ordnance and Ammunition and as Vice-Chairman of the Anti-Aircraft Sub-Committee.

Because Britain had developed many new technologies but lacked the industrial capacity to fully exploit them, it was decided to share them with the United States, although that nation was not yet at war. The information provided by the Tizard Mission contained some of the greatest scientific advances made during the war. The shared technology included radar technologies, in particular the greatly improved cavity magnetron designed by Oliphant's group at Birmingham, which the American historian James Phinney Baxter III described as "the most valuable cargo ever brought to our shores", the design for the proximity fuze, details of Frank Whittle's jet engine and the Frisch–Peierls memorandum describing the feasibility of an atomic bomb. Though these may be considered the most significant, many other items were also transported, including designs for rockets, superchargers, gunsights and submarine detection devices.

Modern jet fighters primarily rely on radar and infrared seeker missiles to track and destroy enemy planes and laser-guided missiles to attack surface targets, rather than the plane's cannon, which may be just an ancillary weapon for air-to-air combat; although in the ground attack role, cannon fire may be emphasized. However, modern fighter aircraft use gyroscopes and inertial sensors coupled with radar and optical computing gunsights that make the use of tracers in cannon ammunition unnecessary. As long as the pilot can put the "pipper" (aiming point) in the head-up display (HUD) onto the target, he can be assured that the burst will be on target, since the computers automatically compute range, closing rate, deflection, lateral accelerations, and even weather conditions to calculate target lead and aimpoint. Thus one of the primary reasons for using tracers on aircraft in the first place, uncertainty over where the bullets will end up in relation to the target, is removed.

Except for the first delivery order, all U.S. military-issue M4 and M4A1 carbines possess a flat-top NATO M1913-specification (Picatinny) rail on top of the receiver for attachment of optical sights and other aiming devices—Trijicon TA01 and TA31 Advanced Combat Optical Gunsights (ACOG), EOTech 550 series holographic sights, and Aimpoint M68 Close Combat Optic (M68 CCO) being the favorite choices—and a detachable rail-mounted carrying handle. Standards are the Colt Model 920 (M4) and 921 (M4A1). Variants of the carbine built by different manufacturers are also in service with many other foreign special forces units, such as the Australian Special Air Service Regiment (SASR). While the SASR uses weapons of essentially the same pattern built by Colt for export (Colt uses different models to separate weapons for the U.S. military and those for commercial/export purposes), the British SAS uses a variant on the basic theme, the Colt Canada (formerly Diemaco) C8SFW.

A typical SPAAG round might have a muzzle velocity on the order of and might take as long as two to three seconds to reach a target at its maximum range. An aircraft flying at is moving at a rate of about . This means the aircraft will have moved hundreds of meters during the flight time of the shells, greatly complicating the aiming problem to the point where close passes were essentially impossible to aim using manual gunsights. This speed also allowed the aircraft to rapidly fly out of range of the guns; even if the aircraft passes directly over the SPAAG, it would be within its firing radius for under 30 seconds. SPAAG development continued through the early 1950s with ever-larger guns, improving the range and allowing the engagement to take place at longer distances where the crossing angle was smaller and aiming was easier. Examples including the 40 mm U.S. M42 Duster and the 57 mm Soviet ZSU-57-2.

The aim of the British Technical and Scientific Mission was to obtain the industrial resources to exploit the military potential of the research and development work completed by the UK up to the beginning of World , but that Britain itself could not exploit due to the immediate requirements of war-related production. The British shared technology included the cavity magnetron (key technology at the time for highly effective radar; the American historian James Phinney Baxter III later called "the most valuable cargo ever brought to our shores"),James Phinney Baxter III (Official Historian of the Office of Scientific Research and Development), Scientists Against Time (Boston: Little, Brown, and Co., 1946), page 142. the design for the VT fuze, details of Frank Whittle's jet engine and the Frisch–Peierls memorandum describing the feasibility of an atomic bomb. Though these may be considered the most significant, many other items were also transported, including designs for rockets, superchargers, gyroscopic gunsights, submarine detection devices, self-sealing fuel tanks and plastic explosives.

The current lighthouse, of a prefabricated steel construction, is a white- painted cylindrical tower, high. Built not far from the site of the first lighthouse (though without obstructing the line of fire of the guns) it was designed to be able to be dismantled in the event of war, so as not to provide a landmark for enemy gunsights. It was, from the start, electrically-powered and fully automated: the light was switched on and off at sunset and sunrise automatically, by a patent sun valve; mains electricity was used, but as a backup a petrol generator was provided which was automatically engaged in the event of a power failure; and in the event of the bulb failing an automatic lamp changer would bring a spare bulb into operation (this change being signalled by a warning light mounted on the shore side of the lighthouse). The light displayed two white flashes every ten seconds.

The sight does not interfere with the overall view, particularly when the collimator light is turned off. Both eyes may be used simultaneously for sighting. HUD inside the cockpit of a fighter jet The optical nature of the reflector sight meant it was possible to feed other information into field of view, such as modifications of the aiming point due to deflection determined by input from a gyroscope.Lon O. Nordeen, Air warfare in the missile age, page 265 1939 saw the development by the British of the first of these gyro gunsights, reflector sights adjusted by gyroscope for the aircraft's speed and rate of turn, enabling the display of a lead-adjusted sighting reticle that lagged the actual "boresight" of the weapon(s), allowing the boresight to lead the target in a turn by the proper amount for an effective strike As reflector sight designs advanced after World War II, giving the pilot more and more information, they eventually evolved into the head-up display (HUD).

Based on the Bü 181 B & C parts list of April 1944 and other primary sources The Bü 181 evolved very little during the war, the differences between the B type and the C types were minimal, the most important being the increased autonomy of the C types. The main difference between the B-1 & C-1 and the B-2 and C-2 sub-types was the presence of pitot heating and position & cabin lights while the B-2 and C-2 types lacked any electrical system.

Ford 2007, p. 36. The fighters were purchased without "government- furnished equipment" such as reflector gunsights, radios and wing guns; the lack of these items caused continual difficulties for the AVG in Burma and China. The 100 P-40 aircraft were crated and sent to Burma on third country freighters during spring 1941. At Rangoon, they were unloaded, assembled and test flown by personnel of Central Aircraft Manufacturing Company (CAMCO) before being delivered to the AVG training unit at Toungoo.Howard 1991, p. 65. One crate was dropped into the water and a wing assembly was ruined by salt water immersion, so CAMCO was able to deliver only 99 Tomahawks before war broke out. (Many of those were destroyed in training accidents.) The 100th fuselage was trucked to a CAMCO plant in Loiwing, China, and later made whole with parts from damaged aircraft. Shortages in equipment with spare parts almost impossible to obtain in Burma along with the slow introduction of replacement fighter aircraft were continual impediments although the AVG did receive 50 replacement P-40E fighters from USAAF stocks toward the end of its combat tour.
