The GAU-23 Bushmaster® Automatic Cannon is a next-generation Chain Gun weapon available and in use today. It continues the Bushmaster tradition of excellence with its design simplicity, external power, positive round control, ease of maintenance, and constant velocity ammunition feed. It incorporates all of the battle-proven features of the 25mm M242 and Mk44 Bushmaster cannons, with significant system commonality for low-risk, proven performance.
The Mk44 Bushmaster® Automatic Cannon has long been the medium-caliber weapon of choice for the world’s ground combat vehicles and naval weapon stations. The GAU-23 type classification establishes the cannon as an airborne weapon for gunship platforms.
In June 2011, the U.S. Air Force announced the conversion of 12 of its Special Operations Command MC-130W Combat Spear aircraft to the Dragon Spear configuration. Orbital ATK also developed and produces the 30mm PGU-46/B High Explosive Incendiary (HEI) ammunition used on this gun system.
In February 2012, Orbital ATK expanded its aviation weapons solution through the development of a Roll-On/Roll-Off (RORO) pallet and weapons mount that integrates with the GAU-23 cannon. The resulting weapons package will allow medium lift platforms the ability to install the system in less than four hours without airframe modification.
