The Army Air Forces Proving Ground Command was the primary testing command of the United States Army Air Forces (1946-47), and then the United States Air Force (1947-57).

The Air Armament Center (AAC) was an Air Force Materiel Command (AFMC) center at Eglin Air Force Base, Florida, responsible for development, acquisition, testing, and deployment of all air-delivered weapons for the U.S. Air Force. Weapon systems maintained by the center included the Advanced Medium Range Air-to-Air Missile, High-speed anti-radiation missile, HARM Targeting System, Joint Air-to-Surface Standoff Missile, Joint Direct Attack Munition, Miniature Air-Launched Decoy, Sensor Fuzed Weapon, and the Small Diameter Bomb. The Air Armament Center was inactivated as an AFMC center on 18 July 2012, and its functions merged into the former 96th Air Base Wing at Eglin AFB. The new organization was renamed as the 96th Test Wing the same day as a subordinate command of the Air Force Test Center at Edwards Air Force Base, California.
