The Bushmaster III automatic cannon is the latest derivative of the Bushmaster cannon. It is intended against emerging threats which require a devastating power to be defeated. As a result of that, the Bushmaster III 50-caliber gun fires different 35mm types of ammunition depending on the target.

In May 2005, ATK received an order from BAE Systems worth $40 million to provide Bushmaster III dual feed chain guns for the Netherlands' CV90 infantry fighting vehicles. Deliveries were scheduled to begin in May 2006.
