Pros and cons


  • Extremely high rate of fire
  • Decent armour penetration
  • Effective against all types of vehicles (ground, air, or naval)


  • High rate of fire requires trigger discipline


One of the most powerful aircraft cannons to ever take to the skies, the GAU-8/A Avenger developed specifically for use on A-10A Thunderbolt II better known as the "Warthog". The A-X program that produced the A-10 was first conceived in September of 1966 when the Air Force recognized a gap in their close air support capabilities for escort and fire suppression and created the A-X program office to develop the specifications for the new aircraft. The request for proposals came out on March 6th, 1967 and specified a 30 mm rotary cannon armament that the aircraft would be designed around. Intended for destroying Soviet armour, the 30 mm cannon received an RFP with specifications of a high muzzle velocity and a rate of fire of 4,000 rounds per minute. General Electric and Philco-Ford both submitted designs for the competition which General Electric won. The Avenger is only one part of a much larger gun assembly that includes a feed system, ammunition drum, and two independent hydraulic motors to power the gun. The complete assembly is officially designated the A/A 49E-6 Gun System and the A-10 is truly built around bringing this beast of a weapon to battle. Making up 16% of the Thunderbolt's unladen weight, the plane requires a special jack for stability when the Avenger is removed for maintenance.

The Avenger is mounted just slightly off-axis to port in order to prevent the recoil from hampering the accuracy of fire during an attack run. The GAU-8/A takes half a second to reach the top firing speed, fires depleted uranium armour-piercing shells for destroying tanks, and can be 80% accurate when firing at 40 foot diameter circle while flying at 4,000 feet. For protection, both the gun and ammo drum are protected by armour designed to detonate enemy shells before they damage the internal components.
