## History
### World War II

The 406th Fighter Squadron was activated ar Richmond Army Air Base, Virginia in the summer of 1943 as one of the three original squadrons of the 371st Fighter Group. The squadron trained in the northeastern United States with Republic P-47 Thunderbolts under First Air Force before moving overseas in the spring of 1944.
Upon arriving in England, the squadron became an element of Ninth Air Force at Bisterne Close, England. The squadron's first combat operation was a fighter sweep over Occupied France. Prior to Operation Overlord, the invasion of Normandy, the 406th flew fighter sweeps, dive bombing and escort missions.
On D-Day the 406th patrolled the beachhead. attacking railroads, trains, vehicles. gun emplacements and other targets. Soon after the invasion, the squadron moved to France and participated in the air interdiction that preceded the Allied breakout at St Lo in late July and supported the following drive across northern France. It continued to operate in northeastern France and southwestern Germany through the winter of 1945, attacking storage dumps, marshalling yard, factories, bridges, roads, and vehicles. In December 1944 it provided close air support for ground forces engaged in the Battle of the Bulge.
The squadron was awarded a Distinguished Unit Citation for its attacks between 15 and 21 March 1945 that contributed to the defeat of Axis forces in southern Germany. It continued combat operations until the Surrender of Germany in May. The squadron remained with the occupation forces in Germany until October 1945 when it returned to the United States and was inactivated.

### Cold War

The 506th Air Refueling Squadron was established on 25 September 1953 by Strategic Air Command (SAC) at Dow AFB and initially equipped with rigid flying boom KB-29P Superfortress tankers. Its mission was to provide in-flight refueling to the Republic F-84 Thunderjet strategic fighters of its parent wing. The squadron also supported other USAF units as directed. In 1954 the squadron deployed to Kindley Air Force Base, Bermuda to support SAC fighters of the 508th Strategic Fighter Wing.
In 1955 SAC concentrated its strategic fighter units, and the 506th's parent 506th Strategic Fighter Wing moved to Tinker Air Force Base, Oklahoma in March. The squadron remained at Dow and was reassigned to the 4060th Air Refueling Wing until August, when it moved to Bergstrom Air Force Base, Texas, where it was assigned to the 42d Air Division, the parent of the 12th Strategic Fighter Wing, to which the squadron was attached.
The 506th was inactivated at Bergstrom on 1 July 1957 and its mission, personnel, and equipment were transferred to the 92d Air Refueling Squadron, which was activated that same day to assume SAC resources at Bergstrom as the 42d Air Division and SAC fighter organizations were transferred to Tactical Air Command.
The 406th Fighter Squadron and the 506th Air Refueling Squadron were consolidated in 1985, but the consolidated unit has not been active.
