The Bushmaster III is a 35 mm automatic/semi-automatic cannon designed and built by Alliant Techsystems, based on the 25 mm M242 Bushmaster. The weapon has been selected as primary armament for the CV9035 export versions of the CV90 infantry fighting vehicles (IFV) currently in service with the Danish, Dutch and Estonian armies.[2][3] The Bushmaster III is a chain gun, like the other members of the Bushmaster family, which grants it great dependability and safety from ammunition cook-off even though it does result in lower rates of fire.

50 mm version

The U.S. Army is testing the Bushmaster 50 mm cannon as a counter rocket, artillery, and mortar (C-RAM) and counter unmanned aerial vehicle (C-UAV) weapon. Initially developed under the Extended Area Protection and Survivability Integrated Demonstration (EAPS ID), it has been successfully tested in tracking distant moving targets using interferometric radar as a sensor, fire control computer, and radio frequency transmitter and receiver to launch a course-correcting projectile. The command guided interceptors have a thruster that receives commands for maneuvering and warhead detonation, with a tantalum-tungsten alloy liner to form forward propelled penetrators to defeat C-RAM targets, and steel body fragments to destroy UAVs.[4][5] The systems can destroy UAVs at a range of 1 km (0.62 mi) and at a height of 1,500 m (4,900 ft).[6]

The caliber is the NATO standard 35x228 introduced by the Oerlikon KD in the 1950s. Bushmaster III can be converted to a caliber of 50×228 mm, which involves changing the barrel and a few key parts, to use the SuperShot 50 cartridge.
