The Hughes M230 Chain Gun is a 30 mm, single-barrel automatic cannon developed by Hughes and now manufactured by Alliant Techsystems. It is an electrically operated chain gun, a weapon that uses external electrical power (as opposed to recoil or expanding gas generated by the firing cartridge) to cycle the weapon between shots. == 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 20 mm round.〔Richardson & Peacock, 1992, pp. 38–40.〕 By April 1973, the program had fired test rounds in more powerful 30 mm 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 eventually adopted as the AH-64 Apache, with the model C as standard armament. The linked ammunition version was intended for the AH-1S Cobra, but was later dropped.
