The A-10 with its GAU-8/A gun entered service in 1977. This vehicle is unique to the A-10 and the GAU-8. The gun is loaded using Syn-Tech's linked tube carrier GFU-8/E 30 mm Ammunition Loading Assembly cart. The front landing gear is positioned to the starboard side. The gun is mounted slightly to the port side with the active firing cannon barrel on the starboard side at the 9 o'clock position and on the aircraft's center line. GAU-8 closeup GAU-8 with barrel shroud visible Because the gun plays a significant role in maintaining the A-10's balance and center of gravity, a jack must be installed beneath the airplane's tail whenever the gun is removed for inspection in order to prevent the aircraft from tipping rearwards. Once completed, the entire GAU-8 assembly (correctly referred to as the A/A 49E-6 Gun System) represents about 16% of the A-10 aircraft's unladen weight. Both of the A-X prototypes, the YA-10 and the Northrop YA-9, were designed to incorporate the weapon, although it was not available during the initial competition the M61 Vulcan was used as a temporary replacement. The specification for the cannon was laid out in 1970, with General Electric and Philco-Ford offering competing designs. The GAU-8 was created as a parallel program with the A-X (or Attack Experimental) competition that produced the A-10. The GAU-8/A is currently produced by General Dynamics. The GAU-8/A is also used in the Goalkeeper CIWS ship weapon system, which provides defense against short-range threats such as highly maneuverable missiles, aircraft, and fast maneuvering surface vessels. Designed to destroy a wide variety of ground targets, the Avenger delivers very powerful rounds at a high rate of fire. The General Electric GAU-8/A Avenger is a 30 mm hydraulically driven seven-barrel Gatling-style autocannon that is primarily mounted in the United States Air Force's Fairchild Republic A-10 Thunderbolt II.
