Ordnance QF 6-pounder
The Ordnance quick-firing 6-pounder 7 cwt,British forces traditionally denoted smaller ordnance by the weight of its standard projectile, in this case approximately . The approximate weight of the gun barrel and breech, "7 cwt" (cwt = hundredweight), was included in the designation to distinguish this gun from others also firing a 6 lb projectile. or just 6-pounder, was a British 57 mm gun, serving during the Second World War as a primary anti-tank gun of both the British and United States Army (as the 57 mm gun M1). It was also used as the main armament for a number of armoured fighting vehicles. Although designed before the start of the war, it did not reach service until the North African Campaign in April 1942, where it replaced the 2-pounder as an anti-tank gun, allowing the 25-pounder gun-howitzer to revert to its intended artillery role. Development and production Development Limitations of the existing 2-pounders were apparent even as the gun entered se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Many variants were produced, often under license, which ranged in length from 40 to 58 calibres, with 40 calibre the most common. 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 artillery, coastal defence guns, the first tank guns and as anti-aircraft guns, whether on improvised or specialized Glossary of British ordnance terms#HA/LA, HA/LA mounts. During World War II 6-pounder guns were put back in service to arm small warships and as coastal defence guns. The last ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QF 6 Pounder 10 Cwt Gun
The British QF (quick-firing) 6-pounder 10 cwt gun"6 pounder" refers to the approximate weight of projectiles, which was a traditional British way of denoting small guns. "10 cwt" referred to the approximate weight of the gun and breech in hundredweight (cwt) rounded up : 10 cwt = 10 × 112 pounds = . It was standard British practice to differentiate guns of the same calibre by adding weight in cwt to the description. was a 57 mm twin-mount light coast defence and naval gun from the 1930s to 1950s. Development Following the emergence of small fast attack craft during the First World War, it was decided that the British Royal Navy Dockyards were vulnerable to attack by motor torpedo boats which had the speed to evade the heavy coast defence guns which defended them. In 1925, a design was adopted for a twin-barrelled weapon capable of sustained semi-automatic fire. The barrels of the weapon could be fired singly or together. The pedestal mounting and the gun crew were enc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1841 6-pounder Field Gun
The M1841 6-pounder field gun was a bronze smoothbore muzzleloading cannon that was adopted by the United States Army in 1841 and used from the Mexican–American War to the American Civil War. It fired a round shot up to a distance of at 5° elevation. It could also fire canister shot and spherical case shot (shrapnel). The cannon proved very effective when employed by light artillery units during the Mexican–American War. The cannon was used during the early years of the American Civil War, but it was soon outclassed by newer field guns such as the M1857 12-pounder Napoleon. In the U.S. Army, the 6-pounders were replaced as soon as more modern weapons became available and none were manufactured after 1862. However, the Confederate States Army continued to use the cannon for a longer period because the lesser industrial capacity of the South could not produce new guns as fast as the North. Background By the early 1800s gun-founders knew that two metals were suitable for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Artillery In The Age Of Sail
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 naval artillery pieces 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 which mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZSU-57-2
The ZSU-57-2 Ob'yekt 500 is a Soviet Union, Soviet self-propelled anti-aircraft gun (SPAAG), armed with two 57 mm autocannons. 'ZSU' stands for ''Zenitnaya Samokhodnaya Ustanovka'' (), meaning "anti-aircraft self-propelled mount", '57' stands for the Caliber, bore of the armament in millimetres and '2' stands for the number of gun barrels. It was the first Soviet mass-produced Continuous track, tracked SPAAG after World War II. 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, Attack aircraft, ground-attack aircraft emerged as a significant threat to mechanized units on the move.

AZP S-60
AZP S-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 Southeast Asian countries. History In the late 1940s, the Soviets started to develop a 57 mm anti-aircraft gun, to replace its 37 mm M1939 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 earlier 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 continued the development and fielded the SPAAG version ZSU-57-2 in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASU-57
The ASU-57 was a small, lightly constructed Soviet Union, Soviet assault gun specifically designed for use by Soviet Airborne Forces, 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 con ...

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 Type 97 57 mm tank gun was an improved version (as to function and durability) of the Type 90 57 mm main gun that was used in the 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 Battles 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.Zaloga, Steven J. ''Japanese Tanks 1939–45'', Osprey Publishing, 2007, pp. 11, 12. After ''Nomonhan'', ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
