On Nov. 16, 1970, the Air Force issued a request for proposal for a 30mm rapid fire cannon to use in the A-X Close Air Support aircraft. In June of 1971 General Electric and Philco Ford were selected to build the prototype gun, designated GAU-8. Besides development of the gun, the contract called for the development of four types of ammunition: Armor Piercing Incendiary, High Explosive Incendiary, Semi-Armor Piercing High Explosive and Target Practice.
