QF 6 Pounder Hotchkiss
The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 40 to 58 calibers, but 40 caliber was the most common version. 6-pounders were widely used by the navies of a number of nations and often used by both sides in a conflict. Due to advances in torpedo delivery and performance, 6-pounder guns were rapidly made obsolete and were replaced with larger guns aboard most larger warships. This led to their being used ashore during World War I as coastal defense guns, the first tank guns and as anti-aircraft guns, whether on improvised or specialized HA/LA mounts. During World War II 6-pounder guns were put back in service to arm small warships and as coastal defense guns. The last ships to carry 6-pounders were the Aegir-cl ...

57 Mm Anti-tank Gun M1943 (ZiS-2)
The ZiS-2 (russian: ЗиС-2) (GRAU index: 52-P-271) is a Soviet Union, Soviet 57 mm anti-tank gun used during World War II. The ZiS-4 is a version of the gun that was meant to be installed in tanks. ''ZiS'' stands for ''Zavod imeni Stalina'' (Russian ''Завод имени Сталина'', 'Factory named after Joseph Stalin, Stalin'), the official title of Artillery Factory No. 92, which produced the gun first. Development In the beginning of 1940 the design office of Vasily Grabin, V. G. Grabin received a task from the artillery department to develop a powerful anti-tank gun. The head of this department, Marshal Grigory Kulik, Kulik, and his subordinates estimated that the use of heavily armoured tanks by the USSR in the Winter War would not have gone unnoticed in Nazi Germany and would lead to the development of similar fighting machines there. There is also a chance that the department was influenced by German propaganda about the experimental multi-turreted "supertank" Ne ...

Naval Artillery In The Age Of Sail
Naval artillery in the Age of Sail encompasses the period of roughly 1571–1862: when large, sail-powered wooden naval warships dominated the high seas, mounting a large variety of types and sizes of cannon as their main armament. By modern standards, these cannon were extremely inefficient, difficult to load, and short ranged. These characteristics, along with the handling and seamanship of the ships that mounted them, defined the environment in which the naval tactics in the Age of Sail developed. Firing Firing a naval cannon required a great amount of labour and manpower. The propellant was gunpowder, whose bulk had to be kept in the magazine, a special storage area below deck for safety. ''Powder boys'', typically 10–14 years old, were enlisted to run powder from the magazine up to the gun decks of a vessel as required. A typical firing procedure follows. A wet swab was used to mop out the interior of the barrel, extinguishing any embers from a previous firing whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZSU-57-2
The ZSU-57-2 Ob'yekt 500 is a Soviet self-propelled anti-aircraft gun (SPAAG), armed with two 57 mm autocannons. 'ZSU' stands for '' Zenitnaya Samokhodnaya Ustanovka'' (russian: link=no, Зенитная Самоходная Установка), meaning "anti-aircraft self-propelled mount", '57' stands for the bore of the armament in millimetres and '2' stands for the number of gun barrels. It was the first Soviet mass-produced tracked SPAAG. In the USSR it had the unofficial nickname "Sparka", meaning "twin mount", referring to the twin autocannon with which the vehicle is armed. Development history Origins During World War II, ground-attack aircraft emerged as a significant threat to mechanized units on the move. Conventional towed anti-aircraft artillery (AAA) was an inadequate response under such conditions owing to the time needed to bring anti-aircraft machine guns into action. This experience made it clear that an anti-aircraft tracked vehicle, armed with small- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AZP S-60
AZP S-60 (russian: Автоматическая зенитная пушка С-60, abbrev. АЗП (AZP); literally: ''Automatic anti-aircraft gun S-60'') is a Soviet towed, road-transportable, short- to medium-range, single-barrel anti-aircraft gun from the 1950s. The gun was extensively used in Warsaw Pact, Middle Eastern and South-East Asian countries. History In the late 1940s, the Soviets started to develop a 57 mm anti-aircraft gun, to replace its 37 mm guns. Three models were presented, and the winning design was made by V. G. Grabin. According to western intelligence sources, the German prototype gun ''5,5 cm Gerät 58'' formed the basis for the design. The Soviets were also able to study German ''5 cm Flak 41'' guns that had been captured following the Battle of Stalingrad. The prototype passed the field tests in 1946 and was accepted into service in 1950, after some minor modifications. The anti-aircraft gun was given the name ''57 mm AZP S-60''. Grabin cont ...

ASU-57
The ASU-57 was a small, lightly constructed Soviet assault gun specifically designed for use by Soviet airborne divisions. From 1960 onwards, it was gradually phased out in favour of the ASU-85. Development history The task to develop a lightweight assault gun for the airborne troops (with either a 57 mm gun or a 76 mm gun) was given to two design bureaus, Astrov (OKB-40) in Mytishchi and Kravtsev in Moscow. Nikolaj Astrov's OKB-40 designed the ASU-76, based on components of the T-70 light tank and the SU-76 assault gun, and armed with the new 76 mm gun D-56T. The ASU-76 turned out to be too heavy, even though the armour was only 3 mm thick, and the project was cancelled. Anatoly Kravtsev's team came up with the similar, amphibious K-73. This vehicle was armed with Charnko's 57 mm anti-tank gun Ch-51 and was even more thinly armoured than the ASU-76. This project too was shelved. In 1949, Astrov was instructed to continue with his project, but with redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 97 57 Mm Tank Gun
The Type 97 57 mm tank gun was originally the main armament of the Imperial Japanese Army Type 97 Chi-Ha medium tank during the Second World War. Design and use The Type 97 Chi-Ha tank was the most widely produced Japanese medium tank of the war, although the armor protection was average for a 1930s tank.Zaloga, Steven J. ''Japanese Tanks 1939–45'', Osprey Publishing, 2007, p. 11. The 57 mm main gun, designed for infantry support, was a carry over from the 1933 Type 89 medium tank. The gun was a short barrelled weapon with a relatively low muzzle velocity, which was sufficient for supporting the infantry. However, in 1939 during the Battle of Khalkhin Gol (Nomonhan) against Soviet BT Tanks, the gun proved to be insufficient against the Soviet armor, causing the Japanese Army to have heavy tank losses. After ''Nomonhan'', new tank guns were developed for the Chi-Ha with a calibre of 47 mm - less than 57 mm tank gun - but having a longer barrel, and better ...

ZiS-30
The ZiS-30 was a light self-propelled anti-tank gun built for the Soviet Red Army in 1941. It was based on the Komsomolets armoured artillery tractor. They were successful vehicles, but production was limited by the number of Komsomolets tractors still in use. Production history The ZiS-30 was one of a few hastily designed armoured fighting vehicles created by Soviet industry shortly after the German invasion during Operation Barbarossa in 1941. In August 1941 Grabin's design bureau at the Gorky plant no. 92 mounted the 57 mm ZiS-2 gun onto the chassis of a Komsomolets artillery tractor. Only around 100 were produced. As one example of its employment, on October 2 the 21st Tank Brigade, under 30th Army in the Kalinin area, included a battery of four ZiS-30s. By October 20 three of these remained on strength. This brigade also had ten T-34-57s which carried the ZiS-4 tank model of the ZiS-2.Jack Radey and Charles Sharp, ''The Defense of Moscow 1941'', Pen & Sword Boo ...

57 55 J
The 57 55 J or ''57 mm, 55 caliber length model Jokinen coastal gun'' is a Finnish light coastal gun designed during the Continuation War. It the first coastal gun designed and manufactured completely in Finland and was intended to replace the older 57 mm Nordenfelt and Hotchkiss guns, but the design was found faulty and only 11 pieces were constructed. They were used for training after World War II until retired in the mid–1960s. Background The gun was developed to replace the older 57 mm Nordenfelt and Hotchkiss guns which, while still usable, were getting old and only had iron sights for aiming. The desire of the Finnish Navy headquarters operational section to begin domestic manufacturing of coastal and naval guns also influenced the decision to develop 57 55 J. The prototype, partially based on the older Nordenfelt and Hotchkiss guns, was designed by Engineering Lieutenant Colonel Antero Albert Jokinen and was finished in 1941 in the Helsinki naval base.

Driggs-Schroeder
Driggs-Schroeder was the name of several naval guns designed by US Navy officers William H. Driggs and Seaton Schroeder for the United States Navy in the late 1880s, fitted on ships built in the 1890s. Some Driggs-Schroeder weapons were also adopted by the US Army. Driggs later founded the Driggs-Seabury Ordnance Company in 1897, in partnership with his brother Louis Labadie "L. L." Driggs and Samuel Seabury, a retired US Navy officer. Driggs-Schroeder weapons included 1-pounder, 3-pounder (Navy Marks 2 and 3), and 6-pounder (Navy Marks 6 and 8)American Ordnance, pp. 37–39 naval guns. All were rapid-firing, which today would be called "single shot", with brass cased ammunition. They were among numerous models of these guns equipped on US Navy ships of the 1890s. Unlike some other manufacturers, Driggs-Schroeder did not design fully automatic 1-pounder and 3-pounder guns. Most Driggs-Schroeder weapons were manufactured by the American Ordnance Company in Bridgeport, Connecticu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
