You might be thinking that, in the year 2018, New York's voting should be proof against a little drizzle.

It cannot give an assurance of blast protection that will be proof against surprise attack or guaranteed against obsolescence or destruction.

Napoleonic French cuirasses were originally intended to be proof against three musket shots at close range; however, this was never achieved in practice. The regulations eventually recognised this, and cuirasses were subsequently only expected to be proof against one shot at long range.Elting, J.R. (1988) Swords Around a Throne: Napoloen's Grande Armée, London, p. 230 The utility of this armour was sometimes disputed.

The longitudinal bulkheads of the side protection system were raised one deck higher to further subdivide the spaces behind the waterline armour belt. The side protection system had a maximum depth of but this decreased significantly as the ship narrowed at its ends. Over the length of the citadel, this system was found to be proof against of TNT during full- scale trials.

It was bounded on the inside by the torpedo bulkhead. Both of the inner and outer voids were fitted with pumps to flood them with water to level the ship (counter-flood) in case she began to list. Over the length of the citadel, this system was found to be proof against of TNT during full-scale trials.Raven and Roberts, pp.

Furutaka and her sister ship Kako were the first generation of high speed heavy cruisers in the Japanese navy, intended to counter the American and British scout cruisers. They developed the experimental design pioneered in the cruiser . Although there were attempts to minimise weight and protection was only designed to be proof against 6 inch shells, the displacement was seriously overweight. The two ships were "scout cruisers", designed with aircraft facilities.

Designed to be proof against typhoons, earthquakes, and other perils, the complex included the main cable station building, several buildings of living quarters, and a self-contained water supply system. The cable connecting Guam to Hawaii was completed in June 1903, marking the complete encirclement of the globe by communications cables. This station became a major communications hub, eventually also housing cables to China and the island of Yap, and becoming an early-warning center for typhoons. Operation of the cable was interrupted by the Japanese capture of Guam in 1941.

The General Staff specification drew on the experience of Centurion tanks in the Korean War as well as that of the Conqueror tank. The tank was expected to be able to engage the enemy at long range, from defensive positions, and be proof against medium artillery. To this end, the gun was to have a greater angle of depression than the 8 degrees of Conqueror and would be equipped with better frontal armour. The tank was expected to achieve a firing rate of 10 rounds per minute in the first minute and six per minute for the following four.

Renault FTs in U.S. service, Juvigny, France Although the concept of the tank had been suggested as early as the 1890s, authorities showed little more than a passing interest in them until the trench stalemate of World War I caused reconsideration. In early 1915, the British Royal Navy and French industrialists both started dedicated development of tanks. Basic tank design combined several existing technologies. It included armor plating thick enough to be proof against all standard infantry arms, caterpillar track (invented in 1770 and perfected in the early 1900s) for mobility over the shell-torn battlefield, the four-stroke gasoline powered internal combustion engine (refined in the 1870s), and heavy firepower, provided by the same machine guns which had recently become so dominant in warfare, or even light artillery guns.
