28th Air Division

28th Air Division ADC AOR 1949–1960

Established in December 1949, the Air Defense Command 28th Air Division "assumed responsibility for conducting the air defense of an area that embraced California, Utah, Nevada, Colorado, and Arizona. It became part of the Western Air Defense Force in 1950. With no fighter interceptor squadrons directly assigned, the division used interceptors of the 78th Fighter Wing, based at Hamilton Air Force Base, California, as well as Air National Guard interceptors based within its geographical area."[2]

"By November 1954 its geographical boundaries included northern California, southern Oregon, and parts of Nevada and Utah. The division participated frequently in air defense exercises with U.S. Army artillery, U.S. Navy interceptors, and Strategic Air Command bombers."[2]

"On 15 February 1959, it added the San Francisco Air Defense Sector to its components, and the geographical area expanded to include California and Arizona, and parts of Oregon, Idaho, Nevada, and New Mexico."[2]

"The division gained the Los Angeles, Phoenix, and Reno Air Defense Sectors and also the 552d Airborne Early Warning and Control Wing, whose Lockheed C-121 Constellation AWACS aircraft augmented naval picket ships in providing radar coverage seaward from the west coast of the United States. During 1961, it transitioned to a Semi Automatic Ground Environment system in all four of its sectors. Reorganization in 1963 altered the 28th's boundaries to include the states of Nevada, Arizona, Utah, and parts of California, Oregon, Idaho, Montana, Wyoming, Colorado, and New Mexico."[2]

"On 1 April 1966, the 28th was reassigned, in name only, to Malmstrom Air Force Base, Montana, and replaced the Great Falls Air Defense Sector. The division's area included Montana and part of North Dakota, and later, parts of South Dakota, Nebraska, and Wyoming. Assumed additional designation of 28th NORAD Region after activation of the NORAD Combat Operations Center at the Cheyenne Mountain Complex, Colorado and reporting was transferred to NORAD from ADC at Ent Air Force Base in April 1966."[2]

The division in the 1960s and 1970s deployed aircraft and personnel from subordinate units in support of the Vietnam War.[2] Became part of ADTAC on 1 October 1979 with the inactivation of ADC and the incorporation of the CONUS air defense mission into Tactical Air Command. Beginning in April 1985, the 28th provided theater and Air Force commands with airborne forces for surveillance, warning, command and control, communications, and electronic combat operations.
