Mauser MK 213
The Mauser MG 213 was a 20 mm aircraft-mounted revolver cannon developed for the ''Luftwaffe'' during World War II. It was never put into service, but the principles formed the basis for several post-war developments by the Allies. A 30 mm version was developed as the MG 213C or MK 213 and it was this that led to the British ADEN, French DEFA and American M39 cannon. Operation The gun was developed by Mauser but, as far as known, was never deployed. It was developed from an earlier design: the MG 213A. The MG 213A utilized a gas-driven operation. In the MG 213, the direct movement of the revolver cassette was changed to a diagonal cam with a follower. This actuated a rammer that both fed cartridges into the cylinders and revolved the cassette. Sealing was accomplished by packing the cylinder and breech with heat resistant steel. This innovation allowed chamber movement while the gas pressure was very high. The revolver cassette had five chambers and at least 3 chambers were ful ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauser
Mauser, originally Königlich Württembergische Gewehrfabrik ("Royal Württemberg Rifle Factory"), was a German arms manufacturer. Their line of bolt-action rifles and semi-automatic pistols has been produced since the 1870s for the German armed forces. In the late 19th and early 20th centuries, Mauser designs were also exported and licensed to many countries which adopted them as military and civilian sporting firearms. The Gewehr 98 in particular was widely adopted and copied, and is the foundation of many of today's sporting bolt-action rifles. History King Frederick I founded the enterprise as Königliche Waffen Schmieden (literally: Royal Weapons Forges) on 31 July 1811. Originally located partly at Ludwigsburg and partly in Christophsthal, the factory transferred to the former Augustine Cloister in Oberndorf am Neckar, where Andreas Mauser worked as the master gunsmith. Of his seven sons who worked with him there, Peter Paul Mauser showed an outstanding ability to deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MK 108 Cannon
The MK 108 (German: ''Maschinenkanone''—"machine cannon") was a 30 mm caliber autocannon manufactured in Nazi Germany, Germany during World War II by Rheinmetall‑August Borsig, Borsig for use in aircraft. The cannon saw widespread use as an anti-bomber weapon during the second half of the war, first seen in 1943 in the Messerschmitt Bf 110, Bf 110G-2 bomber destroyers and Messerschmitt Bf 109, Bf 109G-6/U4. Four MK 108's formed the main armament of the Messerschmitt Me 262, Me 262 the next year. It could be found on some versions or optional mountings on practically every other German fighter aircraft, fighter of the era. Development The weapon was developed as a private venture by the company in 1940 and was submitted to the ''Reich Air Ministry, Reichsluftfahrtministerium'' (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allies of World War II, Allied heavy bombers appearing over German-controlled regions by ...

MG 151 Cannon
The MG 151 (MG 151/15) was a German 15 mm aircraft-mounted autocannon produced by Waffenfabrik Mauser during World War II. Its 20mm variant, the 20 mm MG 151/20 cannon, was widely used on German Luftwaffe Fighter aircraft, fighters, night fighters, fighter-bombers, bombers and ground-attack aircraft. Salvaged guns saw post-war use by other nations. Development and wartime history (MG 151/20) The pre-war German doctrine for arming single-engine fighter aircraft mirrored that of the French. This doctrine favoured a powerful autocannon mounted between the cylinder banks of a V engine and firing through the propeller hub, known as a ''moteur-canon'' in French (from its first use with the Hispano-Suiza 8#Variants, Hispano-Suiza HS.8C engine in World War I, on the SPAD S.XII) and by the cognate ''Motorkanone'' in German by the 1930s. The weapon preferred by the French in this role was the most powerful 20mm Oerlikon of the time, namely the Oerlikon 20 mm cannon, FFS model, b ...

BK 5 Cannon
The Rheinmetall ''Bordkanone'' 5, or BK-5, was a WWII-era German 50 mm autocannon primarily intended for use against Allied heavy bombers, such as the United States Army Air Forces's (USAAF) Boeing B-17 Flying Fortress. The shells had a high muzzle velocity and significant kinetic energy, allowing them to be fired from distances outside the range of the bombers defensive guns. The large explosive content of each shell almost ensured the destruction of any bomber that was hit. Rheinmetall was given a contract in 1943 to adapt the 50 mm 5 cm ''KwK'' 39 tank gun, from the Panzer III tank, for aerial use in the twin-engined Messerschmitt Me 410 ''Hornisse'' bomber destroyer. They were installed as ''Umrüst-Bausätze'' ("factory modification") 4 in the Me 410 A-1/U4, and, experimentally, in two Messerschmitt Me 262 A-1a/U4 jet fighter prototypes (though these were not used operationally),Ziegler, Mano, "Me 262: Hitler's Jet Plane", Greenhill Books, London, ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil Recoil (often called knockback, kickback o ...

Gas-operated Reloading
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle, but subsequently failed to develop that idea further. Between 18 ...

M39 Cannon
The M39 cannon is a 20 mm caliber single-barreled revolver cannon developed for the United States Air Force in the late 1940s. It was used on a number of fighter aircraft from the early 1950s through the 1980s. Development The M39 was developed by the Springfield Armory, based on the World War II–era design of the German Mauser MG 213, a 20 mm (and 30 mm) cannon developed for the Luftwaffe, which did not see combat use. The same design inspired the 30mm British ADEN cannon and the French DEFA, but American designers chose a smaller 20 mm round to increase the weapon's rate of fire and muzzle velocity at the expense of hitting power. The 20×102mm round was later chosen by France for the M621 cannon. Initially designated the T-160, the new gun was installed for combat testing on a number of F-86 Sabre aircraft under the "GunVal" program in late 1952, and used in action over Korea in early 1953. The results of the program were startling, with the GUNVAL F-86F's h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition.

DEFA Cannon
The DEFA cannon (''Direction des Études et Fabrications d'Armement'') is a family of widely-used French-made aircraft revolver cannon firing 30 mm caliber NATO standard rounds. Design history The initial DEFA 551 was developed in the late 1940s. It is based on the German Mauser MG 213C, an experimental revolver cannon developed for the ''Luftwaffe''. The MG 213 never reached production, but inspired the DEFA, the very similar British ADEN cannon, and the smaller American M39 cannon. As the ''DEFA 552'' it entered production in 1954. In 1968 an upgraded version, Canon 550-F3, was developed, entering production in 1971 as the ''DEFA 553''. The new version provided a new feed system, nitro-chrome plated steel barrel, forged drum casing, and improved electrical reliability. Overview The DEFA 553 is a gas-operated five-chamber revolver cannon using pyrotechnic cocking and electrical ignition. It fires a range of 30 mm ammunition of various types, and is capable of continuous fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ADEN Cannon
The Royal Small Arms Factory ADEN cannon (ADEN being an acronym for "Armament Development, Enfield") is a 30 mm revolver cannon used on many military aircraft, particularly those of the British Royal Air Force and Fleet Air Arm. Developed post-World War II primarily to meet British Air Ministry's requirement for increased lethality in aircraft armament, the cannon was fired electrically and is fully automatic once it is loaded. Design and development During World War II, the German firm Mauser began development of a radically new 20 mm autocannon using a motorised firing mechanism in order to improve the rate of fire. The weapon got the preliminary designation Mauser MG 213 and by the late-war period the design was beginning to mature. However the presence of large heavy bombers like the Boeing B-17 Flying Fortress and Avro Lancaster led to the need of up-arming ''Luftwaffe'' fighter aircraft with heavier cannons. Mauser responded to this by adapting the MaschinenGew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
