M230 Chain Gun
The M230 Cannon is a 30 mm (30×113 mm), single-barrel electrically-driven autocannon, using external electrical power (as opposed to recoil or expanding gas generated by the firing cartridge) to cycle the weapon between shots. It was designed and manufactured originally by Hughes Helicopters in Culver City, California. The company was acquired by McDonnell Douglas Helicopters in 1985, which merged into Boeing Corporation in 1997. In 2002, it was sold again to Alliant Techsystems, which merged with Orbital Sciences Corporation in 2015 to form Orbital ATK and was, in turn, bought out by Northrop Grumman in 2018. , it is produced by Northrop Grumman Innovation Systems. Development In 1972, Hughes Helicopters began a company-funded research effort to design a single machine gun to fire the U.S. Army's M50 round.Richardson & Peacock, 1992, pp. 38–40. By April 1973, the program had fired test rounds in more powerful WECOM linked ammunition, from a prototype (A model). In ...

Chain Gun
A chain gun is a type of autocannon or machine gun that uses an external source of power to cycle the weapon's action, rather than diverting excess energy from the cartridges' propellant as in a typical automatic firearm, and does so via a continuous loop of chain drive similar to that used on a motorcycle or bicycle. History In 1972, Hughes Helicopters began a company-funded research effort to design a single machine gun to fire the U.S. Army's M50 round. By April 1973, the program had fired test rounds in more powerful WECOM linked ammunition, from a prototype (A model). In January 1975 a model "C" was added, a linkless version for the proposed Advanced Attack Helicopter YAH-64; the helicopter was later adopted as the Hughes Model 77/AH-64A Apache, with the model C (receiving the designation M230 chain gun) as standard armament. In 1976, Hughes Helicopters successfully patented the chain gun, and it has since been further developed into several other system of different c ...

30 Mm
30 mm caliber is a specific size of popular autocannon ammunition. Such ammunition includes NATO standard 30×113mmB and 30×173mm (STANAG 4624), Soviet 30×155mmB, 30×165mm, and 30×210mmB, Yugoslav 30×192mm, Anglo-Swiss 30×170mm, and Czechoslovak 30×210mm rounds which are widely used around the world. Usage Thirty-millimeter ammunition is typically not used against personnel, but rather as an anti-materiel or armor-piercing round. Rounds of this size can be effective against lightly armored vehicles as well as fortified bunkers. It is also a popular caliber for shipboard close-in weapons systems, such as the Russian AK-630 and Dutch Goalkeeper CIWS. The Armed Forces of the Russian Federation use their 30 mm weapons in a variety of vehicles, including the Su-25 attack aircraft, Mi-24 helicopter, Mi-28 attack helicopter, Ka-50 attack helicopter, and the BMP-2, BMP-3, and BTR-90 infantry fighting vehicles. The most modern anti-aircraft gun systems in use by R ...

Remote Weapon Station
A remote controlled weapon station (RCWS), or remote weapon station (RWS), also known as a remote weapon system (RWS), is a remotely operated weaponized system often equipped with fire-control system for light and medium- caliber weapons which can be installed on a ground combat vehicle or sea- and air-based combat platforms. Such equipment is used on modern military vehicles, as it allows a gunner to remain in the relative protection of the vehicle. It may also be retrofitted onto existing vehicles; for example, the Crows system is being fitted to American Humvees.

MRAP
Mine-Resistant Ambush Protected (MRAP; ) is a term for United States Armed Forces, United States military light tactical vehicles produced as part of the MRAP program that are designed specifically to withstand improvised explosive device (IED) attacks and ambushes. The United States Department of Defense MRAP program began in 2007 as a response to the increased threat of IEDs during the Iraq War. From 2007 until 2012, the MRAP program deployed more than 12,000 vehicles in the Iraq War, War in Iraq and War in Afghanistan (2001–present), War in Afghanistan. Production of MRAP vehicles officially ended in 2012. This was followed by the Oshkosh M-ATV, MRAP All Terrain (M-ATV) vehicle. In 2015, Oshkosh Corporation was awarded a contract to build the Oshkosh L-ATV as the Joint Light Tactical Vehicle, a lighter mine-resistant vehicle to replace the Humvee in combat roles and supplement the M-ATV. History Light armored vehicles designed specifically to resist land mines were f ...

Rolled Homogeneous Armour
Rolled homogeneous armour (RHA) is a type of vehicle armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks. After World War II, it began to fall out of use on main battle tanks and other armoured fighting vehicles intended to see front-line combat as new anti-tank weapon technologies were developed which were capable of relatively easily penetrating rolled homogeneous armour plating even of significant thickness. Today, the term is primarily used as a unit of measurement of the protection offered by armour on a vehicle (often composed of materials that may not actually contain steel, or even contain any metals) in equivalent ''millimetres of RHA'', referring to the thickness of RHA that would provide the same protection. Typically, modern composite armour can provide the same amount of protection with much thinner and lighter construction than its protectiv ...

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 ...

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 ...

Meggitt
Parker Meggitt (formerly Meggitt plc) is a British international company specialising in components and sub-systems for the aerospace, defence and selected energy markets. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index until it was acquired by Parker Hannifin in September 2022. History Origins The company's history spans back to multiple preceding businesses that were originally founded in both the nineteenth and twentieth centuries. Meggitt's own official history claims that the company's roots can be traced through to 1850 via the scientific instrumentation business Negretti & Zambra, which had, amongst other innovations, invented the world's first altimeter for the hot air balloon. During 1947, a new business was founded under the trading name ''Willson Lathes''; it operated as a machine tool manufacturer based in Halifax, West Yorkshire. That same year, Willson Lathes became a quoted public company. During 1964, Meggitt, a Dorset- ...

Cooking Off
Cooking off (or thermally induced firing) is unfired weapon ammunition exploding prematurely due to heat in the surrounding environment. The term is used both for detonation of ammunition not loaded into a weapon, and unintended firing of a loaded weapon due to heating. A fast cook-off is a cook-off caused by fire. A slow cook-off is caused by a sustained thermal event less intense than fire. A cooked-off round may cause a sympathetic detonation of adjacent rounds. Insensitive munitions are designed to be less vulnerable to accidental firing induced by external heat. Artillery Inherent design flaws in early 17th century Swedish leather cannons led to the gun tube overheating which prematurely ignited the gunpowder, injuring the loader. Muzzle-loading cannon on merchant and naval vessels of the Age of Sail would fire if the vessels caught fire while the guns were loaded. Examples include the merchantman and . After the cooking off of artillery shells in the G5 howitzer ...
