History
The 366th Fighter Squadron was activated on 1 January 1943 at Richmond Army Air Base, Virginia as one of the original squadrons of the 358th Fighter Group. The squadron initially began training with the Curtiss P-40 Warhawk. Later that year, the unit replaced its Warhawks with the Republic P-47 Thunderbolt, which it flew for the remainder of the war. The squadron left the United States in September 1943.

The 366th arrived in England during October 1943, where it began operations with Eighth Air Force on 20 December 1943, but was transferred to Ninth Air Force in February 1944. The unit engaged primarily in missions escorting bombers attacking targets on the continent of Europe until April 1944. The squadron then undertook dive bombing missions against marshalling yards and airfields and attacked Axis communications during April and May from its new station, an advanced landing ground at RAF High Halden, to help prepare for the invasion of Normandy.

The squadron escorted troop carrier formations on D Day and the following day as the formations dropped paratroopers on the Cotentin Peninsula. For the remainder of June, it attacked rail lines, troop concentrations, bridges and transport. The squadron moved to France in July and, from its base at Cretteville, took part in operations that resulted in the Allied breakthrough at St Lo. The squadron continued to fly escort, interdiction and close air support missions during the Allied drive across France and into Germany throughout 1944–45.

The squadron received a Distinguished Unit Citation for its actions between 24 December 1944 and 2 January 1945, when it supported the Seventh Army attacking railroads and rolling stock, other vehicles and artillery formations. It also destroyed numerous Luftwaffe fighters while undertaking defensive operations during the German-launched Operation Bodenplatte, an attack concentrating on forward Allied air bases in an attempt by the Luftwaffe to attain air superiority in the area of the Battle of the Bulge. In March, the squadron attacked German forces attempting to withdraw across the Rhine River, destroying motor transport and hampering the withdrawal efforts, earning a second Distinguished Unit Citation. The following month, the squadron attacked German airfields near Munich and Ingolstadt, engaging aircraft and supporting the advance of Allied ground forces in the area, earning a third award of the Distinguished Unit Citation. The squadron was also awarded the French Croix de Guerre with Palm by the Government of France for its assistance in the liberation of France. The squadron was credited with the destruction of 29.5 enemy aircraft during the war.

The squadron remained in Germany after VE Day until July 1945, when it returned to the United States, where it was inactivated on 7 November 1945.
