The 20th Air Division (20th AD) is an inactive Tactical Air Command at Tyndall Air Force Base, Florida where it was inactivated on 1 March 1983.

During most of the division's history it served with Air Defense Command as a regional command and control headquarters. Between 1955 and 1967 the division controlled air defense units in the central United States. It controlled a slightly different areas of the midwestern US from 1955 to 1960 and from 1966 to 1967. Its area of responsibility shifted to the east coast if the United States from 1969 to 1983. It was shifted to its final station on paper in 1983 and was immediately inactivated.


The 20th AD was assigned to Air Defense Command (ADC) for most of its existence. It served as a regional command and control headquarters, controlling fighter interceptor and radar units over several areas of responsibility during the Cold War. For three years it also commanded a surface-to-air missile squadron.

The division was initially activated as an intermediate command organization of Central Air Defense Force at Grandview (later, Richards-Gebaur) AFB in June 1955.[1] The 20th AD was responsible for the interceptor and radar units within an area that covered parts of Nebraska, Oklahoma, Arkansas, Illinois, Iowa, and virtually all of Kansas and Missouri.[2]

On 1 October 1959 ADC activated the 33d Air Division assumed command of most of its former units.[1][4]

The division was reactivated in 1966 under Chicago Air Defense Sector when ADC discontinued its air defense sectors and replaced them with air divisions.[5] The 20th provided air defense from the Truax Field, Wisconsin DC-7/CC-2 SAGE blockhouse for parts of Wisconsin, Minnesota, Iowa, Missouri, Arkansas, Tennessee, Kentucky, Indiana, and all of Illinois.[2] The division also acted as the 20th NORAD Region after activation of the North American Air Defense Command (NORAD) Combat Operations Center at Cheyenne Mountain, Colorado. Operational control of the division was transferred to NORAD from ADC.

In addition to the active duty interceptor and radar units, the 20th AD supervised Air National Guard units that flew interception sorties using (among other aircraft) McDonnell F-101 Voodoos and Convair F-106 Delta Darts. At the same time the division controlled numerous radar squadrons. It was inactivated in 1967 as part of an ADC consolidation of intermediate level command and control organizations, driven by budget reductions required to fund USAF operations in Southeast Asia.

The 20th AD was activated for a third time in November 1969 under Aerospace Defense Command (ADCOM).[1] The division provided air defense for virtually all of the southeastern United States, except for most of Louisiana from the SAGE DC-4 blockhouse at Fort Lee AFS, Virginia.[6] The division also controlled a CIM-10 Bomarc surface-to-air anti-aircraft missile squadron near Langley AFB until the squadron's inactivation in October 1972.[7]

ADCOM was inactivated on 1 October 1979. The atmospheric defense resources (interceptors and warning radars) of ADCOM were reassigned to Tactical Air Command, which formed Air Defense, Tactical Air Command (ADTAC) as the headquarters to control them.[8] After 1981, the division controlled units equipped with McDonnell Douglas F-15 Eagle aircraft. Its subordinate units continued to participate in intensive academic training, numerous multi-region simulated (non-flying) exercises, and flying exercises.

The 20th AD moved to Tyndall AFB, Florida in March 1983 where its mission, personnel and equipment was transferred to the Southeast Air Defense Sector.
