In December 1955, the Air Munitions Development Laboratory was reassigned from the Wright Air Development Center at Wright-Patterson AFB, Ohio, to the Air Force Armament Center at Eglin by Headquarters Air Research and Development Command. The responsibility for development of guns, bombs, rockets, fuses, guided missile warheads and other related equipment in the armament field was transferred from the Dayton, Ohio facility at this time. Work on nuclear weapons was not included in this mission. The USAF Special Air Warfare Center was activated 27 April 1962, with the 1st Combat Applications Group (CAG) organized as a combat systems development and test agency under the SAWC. The 1st CAG concentrated on testing and evaluation of primarily short-term projects which might improve Air Force counter-insurgency (COIN) operations. The Special Air Warfare Center, located at Hurlburt Field, undertook to develop tactical air doctrine while training crews for special air warfare in places like Southeast Asia. By mid-1963, SAW groups were in Vietnam and Panama. The USAF Tactical Air Warfare Center was activated on 1 November 1963. It would be re-designated as the USAF Air Warfare Center on 1 October 1991. With the increasing U.S. involvement in Southeast Asia in the 1960s, the need for increased emphasis on conventional weapons development made Eglin's mission even more important. On 1 August 1968, the Air Proving Ground Center was redesignated the Armament Development and Test Center to centralize responsibility for research, development, test and evaluation, and initial acquisition of non-nuclear munitions for the Air Force. On 1 October 1979, the Center was given division status. The Armament Division, redesignated Munitions Systems Division on 15 March 1989, placed into production the precision-guided munitions for the laser, television, and infrared guided bombs; two anti-armor weapon systems; and an improved hard target weapon, the GBU-28, used in Operation Desert Storm during the Persian Gulf War. The Division was also responsible for developing the Advanced Medium Range Air-to-Air Missile (AMRAAM), an Air Force-led joint project with the U.S. Navy. The Air Force Armament Museum was founded on base in 1975. In 1981 the original building housing the museum was condemned and the facility closed until 1984. Selected on 27 April 1975, the installation served as one of four main U.S. Vietnamese Refugee Processing Centers operated by the Interagency Task Force for Indochina Refugees, where base personnel housed and processed more than 10,000 Southeast Asian refugees, the first 374 of which arrived on board a Northwest Orient Boeing 747 on 4 May 1975.
