Bushmaster III

The Bushmaster III is an automatic/semi-automatic cannon designed and built by Alliant Techsystems. It is based on the M242 Bushmaster originally developed by Alliant Techsystems. The weapon has been selected as primary armament for export version of the CV90 infantry fighting vehicles (IFV) currently in service by the Danish, Dutch and Estonian armies.

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. 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).
