# 501st Combat Support Group

The 501st Combat Support Group is an inactive United States Air Force organization. It was last active as part of the 501st Tactical Missile Wing at RAF Greenham Common, England, where it provided support for the wing and tenant organizations as the host organization for Greenham Common rom 1982 to 1991.
The group was originally activated as the 501st Air Service Group, a support group, at the end of World War II and continued this mission with the American occupation forces in Germany through the beginning of the Berlin Airlift, when it was inactivated as United States Air Forces Europe implemented the wing base organization system. In 1982 the group was consolidated with the 501st Base Headquarters and Air Base Squadron, a Second Air Force unit that provided base support at Great Bend Army Air Field, Kansas from 1943 to 1944.
The group was activated once again in 1953 as the 501st Air Defense Group, when Air Defense Command (ADC) established it as the headquarters for a dispersed fighter-interceptor squadron and the medical, aircraft maintenance, and administrative squadrons supporting it. It was replaced in 1955 when ADC transferred its mission, equipment, and personnel to the 56th Fighter Group in a project that replaced air defense groups commanding fighter squadrons with fighter groups with distinguished records during World War II.

## History
### World War II and Occupation of Germany

The earliest predecessor of the 501st Combat Support Group was the 501st Base Headquarters and Air Base Squadron, which was organized in 1943 as the headquarters for Great Bend Army Air Field, Kansas, a World War II very heavy bombardment training base. Great Bend was one of the original bases where Boeing B-29 Superfortress units received their training before deploying to the China Burma India Theater. However, the Army Air Forces (AAF) found that standard military units, based on relatively inflexible tables of organization were proving themselves less well adapted to the training mission. Accordingly, a more functional system was adopted in which each base was organized into a separate numbered unit. This resulted in the 501st, along with other units at Great Bend, being disbanded and its personnel, equipment and functions transferred to the 243d AAF Base Unit (Operational Training Unit, Very Heavy).
The 501st Air Service Group was established toward the end of World War II to provide support for flying units in Germany and Austria from 1945 to 1948 as part of a reorganization of AAF support groups in which the AAF replaced service groups that included personnel from other branches of the Army and supported two combat groups with air service groups including only Air Corps units. It was designed to support a single combat group. Its 919th Air Engineering Squadron provided maintenance that was beyond the capability of the combat group, its 743rd Air Materiel Squadron handled all supply matters, and its Headquarters & Base Services Squadron provided other support. The group moved to Wiesbaden Air Base, Germany, where it replaced the 97th Airdrome Squadron as the primary support unit for the airfield. It briefly supported the Berlin Airlift before inactivation in 1948. It was replaced by elements of the 7150th AF Composite Wing in the Air Force wing base reorganization in 1948. which was adopted to unify control at air bases The group was disbanded later in 1948.

### Air Defense of the United States

During the Cold War, the group was reconstituted, redesignated as the 501st Air Defense Group, and activated by Air Defense Command (ADC) at O'Hare International Airport on 16 February 1953 with responsibility for air defense in the Great Lakes area. It was assigned the 62d Fighter-Interceptor Squadron, which was already stationed at O'Hare, flying North American F-86 Sabres as its operational component. The 62d had been assigned directly to the 4706th Defense Wing prior to the activation of the 501st Group. The group replaced the 83rd Air Base Squadron as USAF active duty host organization at O'Hare. It was assigned three squadrons to perform its support responsibilities.
The group added a second operational unit, the 42d Fighter-Interceptor Squadron, which was activated at O'Hare eight days after the group headquarters, and also Flew F-86s. In March 1953, the 62d Squadron converted to newer radar equipped and Mighty Mouse rocket armed North American F-86Ds. The group was inactivated and replaced by the 56th Fighter Group in 1955 as part of ADC's Project Arrow, which was designed to bring back on the active list the fighter units which had compiled memorable records in the two world wars.

### Ground Launched Cruise Missile Support

In the early 1980s USAF began deploying Ground Launched Cruise Missiles in the European theater. The 501st Tactical Missile Wing was organized at RAF Greenham Common as the first USAF wing equipped with the BGM-109 Tomahawk missile. The 501st group was redesignated the 501st Combat Support Group and activated as the headquarters for organizations supporting the wing and hosted all USAF organizations at Greenham Common. As the Intermediate-Range Nuclear Forces Treaty was implemented, the USAF withdrew its missiles from Europe and the wing and group were inactivated.
