AC-47s mounted three General Electric GAU-2 (M134) miniguns that fired 2,000 7.62mm rounds per minute (downrated from 6,000 rpm) from six rotating barrels. The miniguns were mounted in SUU-11/A aircraft gun pods, each of which held 1,500 rounds. Pilots generally fired about five-second bursts. (Courtesy of Steve Birdsall)
