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.[1] As of 2019[update], it is produced by Northrop Grumman Innovation Systems.[3]
