The Combat Vehicle 90 (CV90) is a family of Swedish tracked armoured combat vehicles designed by the Swedish Defence Materiel Administration (FMV), Hägglund & Söner and Bofors during the mid-1980s to early 1990s, before entering service in Sweden in the mid-1990s. The CV90 platform design has continuously evolved from the Mk 0 to the current Mk IV with technological advances and changing battlefield requirements.
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber 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, 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.
A mortar is today usually a simple, lightweight, man-portable, muzzle-loaded cannon, consisting of a smooth-bore metal tube fixed to a base plate with a lightweight bipod mount and a sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy siege artillery. Mortars launch explosive shells in high-arching ballistic trajectories.
Alliant Techsystems Inc. (ATK) was an American aerospace, defense, and sporting arms firm headquartered in Arlington County, Virginia, in the United States. The company operated in 22 states, Puerto Rico, and internationally. ATK revenue in fiscal year 2014 was about US$4.78 billion.
A chain gun is a type of autocannon or machine gun that uses an external source of power to cycle the weapon's action via a continuous loop of chain similar to that used on a motorcycle or bicycle, instead of diverting excess energy from the cartridges' propellant as in a typical automatic firearm.
The M230 Cannon is a 30 mm (30×113 mm), single-barrel electrically-driven autocannon, using external electrical power to cycle the weapon between shots. It was designed and manufactured originally by Hughes Helicopters in Culver City, California. As of 2019, it is produced by Northrop Grumman Innovation Systems.
The HS.404 is an autocannon originally designed by and produced by the Swiss arm of the Spanish/Swiss company Hispano-Suiza in the mid-1930s. Production was later moved to the French arm of Hispano-Suiza.
The M242 Bushmaster chain gun is a 25 mm (25×137mm) single-barrel chain-driven autocannon. It is used extensively by the U.S. military, such as in the Bradley fighting vehicle, as well as by other NATO members and some other nations in ground combat vehicles and various watercraft. Hughes Helicopters in Culver City, California, was the original designer and manufacturer. As of 2019, Northrop Grumman Innovation Systems produces the gun.
The XM25 Counter Defilade Target Engagement (CDTE) System, also known as the Punisher and Individual Semiautomatic Air Burst System was an airburst grenade launcher with programmable ammunition derived from the XM29 OICW. It was fielded to soldiers serving in the War in Afghanistan in 2010, after which malfunctions and 2013 program budget cuts delayed official entry into service, planned for early 2017. In early 2017, the contract with Orbital ATK was cancelled, calling the future of the entire program into question. The program was officially terminated on 24 July 2018.
The Mk44 Bushmaster II is a 30 mm chain gun manufactured by Northrop Grumman. It is a derivative of the 25 mm M242 Bushmaster, and uses 70% of the same parts as the M242 while increasing the firepower by as much as 50% with the 20% increase in caliber size. The barrel is chromium-plated for extended life. The gun uses standard GAU-8 Avenger ammunition that is available in API, HEI and APFSDS-T variants.
The Rheinmetall Mk 20 Rh-202 is a 20 mm caliber autocannon designed and produced by Rheinmetall. It fires the 20×139mm ammunition originally developed for the Hispano-Suiza HS.820.
The Shipunov 2A42 is a Soviet/Russian 30 mm autocannon. It is built by the Tulamashzavod Joint Stock Company and named after A. G. Shipunov.
The CM-32 "Clouded Leopard", officially Taiwan Infantry Fighting Vehicle (TIFV), is an eight-wheeled armoured vehicle currently being produced for the Republic of China Army. It is based on the 6x6 CM-31 designed by Timoney Technology Limited of Ireland and is further developed by the Ordnance Readiness Development Center.
The M1156 Precision Guidance Kit (PGK), formerly XM1156, is a U.S. Army-designed precision guidance system to turn existing 155 mm artillery shells into smart weapons. The prime contractor was Alliant Techsystems – later merging with Orbital Sciences Corporation to form Orbital ATK, in turn being taken over by Northrop Grumman and renamed Northrop Grumman Innovation Systems – and the industry team includes Interstate Electronics Corporation. By April 2018, more than 25,000 PGKs had been produced.
The Oerlikon KBA is a 25 mm (25×137mm) autocannon, developed as a close range multipurpose weapon for the mechanised battlefield, originally made by Oerlikon and currently produced in Rheinmetall Italia S.p.A. facilities. It is a positively locked breech, gas and recoil operated cannon with a rotating bolt head and a dual-belt selective feed system taking a 25mm NATO cartridge. The rate of fire in burst mode is 600 rounds per minute but it can be adjusted electronically and reduced to single shot or a selectable range from 100 up to 200 rounds per minute.
The Bushmaster IV is a 40 mm chain-driven autocannon designed and built by Alliant Techsystems, based on the M242 Bushmaster, Bushmaster II and Bushmaster III. The Bushmaster IV fires 40×365mmR 3P, APFSDS-T Mk I, and APFSDS-T Mk II rounds. The 3P round will provide air burst capability and the APFSDS-T Mk II can penetrate armor with a thickness in excess of 150 millimeters.
Oto Melara Hitfist is a two-man turret, for armored vehicles, developed by the Italian Oto Melara. The turrets are designed to mount a 25mm Oerlikon KBA or 30/40mm ATK Mk44 Bushmaster II autocannon. The main armament may mount a co-axial machine gun. A variant allows the operator to aim and fire anti-tank missiles.
The Mark 38 25 mm machine gun system (MGS) is a shipboard weapon system designed to protect warships primarily from a variety of surface threats, especially small, fast surface craft. It consists of an M242 Bushmaster chain gun mounted on a turret that can be either manually or remote controlled, depending on variant. Originally designed by the United States in the 1980s for use on their warships, the Mark 38 is today in service on warships of various NATO countries.
