Mk44 Bushmaster II
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 (Armor-Piercing Incendiary), HEI (High-Explosive Incendiary) and APFSDS-T (Armor-Piercing Fin-Stabilized Discarding Sabot-Tracer) variants. The gun can be converted to a caliber of 40x180 mm, which involves changing the barrel and a few key parts, to use the SuperShot 40 cartridge. It can also be converted to use the 30x170 mm RARDEN cartridge. History The Bushmaster II is the standard primary armament of the Bionix-II AFV currently in service with the Singapore Army, the KTO Rosomak in Polish service, and the CV90 AFVs in Finnish, Norwegian and Swiss service.

Hunt-class Mine Countermeasures Vessel
The Hunt class is a class of thirteen mine countermeasure vessels of the Royal Navy. As built, they combined the separate roles of the traditional minesweeper and that of the active minehunter in one hull, but later modifications saw the removal of mine-sweeping equipment. They have a secondary role as offshore patrol vessels. Development Upon introduction in the early 1980s they were the largest warships ever built out of glass-reinforced plastic and were the last in operation to use the Napier Deltic diesel engine. All were built by Vosper Thornycroft in Woolston except and , which were built by Yarrow Shipbuilders Limited on the River Clyde. was the last ship of the class launched. Following the sale of and to the Greek Navy, the sale of and to the Lithuanian Navy and the decommissioning of , a contract to re-engine the remaining eight vessels was signed by BAE Systems in 2008, whereby the existing 30-year old Napier Deltic 9-59K power units were replaced by Cat ...

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 ...

Martlet (missile)
Martlet is a lightweight air-to-surface, surface-to-air, and surface-to-surface missile developed by Thales Air Defence for the United Kingdom. It is named after a mythical bird from English heraldry that never roosts, the martlet. Developed as the Lightweight Multirole Missile (LMM) to meet the UK's "Future Air-to-Surface Guided Weapon (Light)" requirement, the Ministry of Defence (MOD) placed an initial order for 1,000 missiles with deliveries due to start in 2013. However, initial operating capability was considerably delayed and took place in 2021 with full operating capability anticipated in 2024. The missile was given the name "Martlet" in British service. Development The Lightweight Multirole Missile was initially conceived as Thales' response to the MoD's Future Air-to-Surface Guided Weapon (Light) FASGW(L) requirement. It was designed to be launched from a variety of naval, air and land platforms against a wide range of targets. High precision reduces collateral damag ...

Remote Controlled 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.
