The M242 Bushmaster is a 25 mm (25×137mm) chain-fed autocannon. It is used extensively by the US armed forces, as well as by NATO's and some other nations' forces in ground vehicles and watercraft. Originally, the weapon was designed and manufactured by McDonnell Douglas (later acquired by the Boeing Corporation); however it is now produced by Alliant Techsystems (ATK) of Mesa, Arizona.
