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. The caliber is the NATO standard 35×228 introduced by the Oerlikon KD in the 1950s.

50 mm version

Main article: XM913 chain gun

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] Converting the Bushmaster III to 50×228 mm can be accomplished by changing the barrel and a few key parts allowing it to fire the SuperShot 50 cartridge.

Separately, under the Army's Advanced Lethality and Accuracy System for Medium Caliber (ALAS-MC) effort, Northrop Grumman was contracted to develop a 50 mm version of the Bushmaster III called the XM913 for the Next Generation Combat Vehicle (NGCV), later designated the XM30 Mechanized Infantry Fighting Vehicle, that would replace the Bradley Fighting Vehicle.[7]
