Oerlikon KCA
The Oerlikon KCA is a Swiss gas-operated single-barrel revolver cannon developed for aircraft use. Its most noticeable use was on the JA 37 Viggen fighter mounted in a conformal pod as the ''akan m/75''. The KCA fires a shell that is 50% heavier than the NATO The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two N ... standard ammunition used on ADEN and DEFA cannon.

Automatic Cannon
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, they are typically installed on fixed mounts, wh ...

Revolver Cannon
A revolver cannon is a type of autocannon, commonly used as an aircraft gun. It uses a cylinder with multiple chambers, like those of a revolver handgun, to speed up the loading-firing-ejection cycle. Some examples are also power-driven, to further speed the loading process. Unlike a rotary cannon, a revolver cannon only has a single barrel, so its spun weight is lower. Automatic revolver cannons have been produced by many different manufacturers. History Precursors An early precursor was the Puckle gun of 1718, a large flintlock revolver gun, manually operated. The design idea was impractical, far ahead of what 18th century technology could achieve. During the 19th century, Elisha Collier and later Samuel Colt used the revolver action to revolutionize handguns. The Confederate States of America used a single 2-inch, 5-shot revolver cannon with manually rotated chambers during the Siege of Petersburg. The gun was captured in Danville, Virginia by Union forces on April ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab 37 Viggen
The Saab 37 Viggen ( Swedish for ''"the Bolt"'' or ''"the Tufted Duck"'' ( see name)) is a retired Swedish single-seat, single-engine, short-medium range combat aircraft. Development work on the type was initiated at Saab in 1952 and, following the selection of a radical delta wing configuration, the resulting aircraft performed its first flight on 8 February 1967 and entered service in 21 June 1971. It was the first canard design produced in quantity.Fredriksen 2001, p. 279. The Viggen was also the most advanced fighter jet in Europe, albeit slower than the earlier MiG-21bis, until the introduction of the Panavia Tornado into operational service in 1981. Several distinct variants of the Viggen were produced to perform the roles of strike fighter (AJ 37), aerial reconnaissance (SF 37), maritime patrol aircraft (SH 37) and a two-seat trainer (Sk 37). In the late 1970s, the all-weather fighter-interceptor aircraft JA 37 variant was introduced. In November 2005, the Viggen wa ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is '' animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while ...

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 MaschinenG ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 contin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oerlikon-Contraves
Rheinmetall Air Defence AG is a division of German armament manufacturer Rheinmetall, created when the company's Oerlikon Contraves unit was renamed on 1 January 2009 and integrated with Rheinmetall's other air-defence products. Oerlikon Contraves was a Swiss anti-aircraft artillery manufacturer famous for its adaptation of the 1916 20 mm Becker as the Oerlikon 20 mm autocannon design, which was used in the Second World War and still in use today. Copies and derivatives of these designs were made by German, French, British and Japanese weapon manufacturers. Oerlikon Contraves was purchased by Rheinmetall in 1999. , Rheinmetall Air Defence had around 1,050 employees at locations in Switzerland, Germany, Italy and Canada. The group's sales were about . History Oerlikon's earliest predecessor was Schweizerische Werkzeugmaschinenfabrik Oerlikon, founded in the Oerlikon district of Zurich, Switzerland in 1906. In 1923 it acquired a factory in Germany. It entered the ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30 Mm Artillery
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...
