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. 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.
