 The GAU-8/A Avenger is a seven-barrel Gatling-style machine gun that is primarily used by the United States Air Force's A-10 Thunderbolt II ground-attack aircraft.

The development of the GAU-8/A Avenger began in the late 1960s when the United States Air Force began to search for a replacement for its aging GAU-4 7.62mm machine gun, which was mounted on the A-1 Skyraider and A-37 Dragonfly aircraft.

The development of the GAU-8/A Avenger was entrusted to General Electric, who had previously developed the M61 Vulcan cannon, another Gatling-style machine gun that was used by the United States Air Force on its F-4 Phantom, F-15 Eagle, and F-16 Fighting Falcon fighter aircra
