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.
