in defeating the Wehrmacht during the Battle of the Bulge. Initially American, British, and Canadian air power was grounded by very bad winter weather, but then the bad weather broke, freeing the tactical air forces to help break the back of the Wehrmacht attack. The long smash across France, Belgium, and Luxembourg was the highlight of the existence of the 9th Air Force. In the spring of 1945, Ninth Air Force troop carrier units flew airborne parachute and glider units again during Operation Varsity, the Allied assault over the Rhine River on 24 March 1945. Operation Varsity was the single largest airborne drop in history. The operation saw the first use of the Curtiss-Wright C-46 Commando transport in Europe, operating with the reliable C-47 Skytrain of previous airborne operations, an experiment which ended with the catastrophic loss of 28% of the C-46s participating. Postwar demobilization Ninth Air Force tactical air support operations were flown over western Germany until the end of hostilities on 7 May. However, once the victory had been gained, the United States plunged into demobilization, just as it had done at the end of the First World War. Most officers and men were sent back to the United States and their units inactivated. Others were assigned to the new United States Air Forces in Europe and were moved to captured Luftwaffe airfields to perform occupation duties. Some transport units relocated to France. Finally, with the mission completed, on 2 December 1945 the Ninth Air Force was inactivated at USAFE Headquarters at Wiesbaden Germany.

After several relocations, on 20 August 1954, Ninth Air Force Headquarters was assigned to Shaw Air Force Base, South Carolina, where it remains today. The postwar Numbered Air Forces were components of the new major command structure of the United States Air Force, and Ninth Air Force became one of the tactical air forces of the new Tactical Air Command. Ninth Air Force commanded TAC Wings east of the Mississippi River. Initially being equipped with propeller-driven F-51, F-47 and F-82 aircraft during the postwar years, in the 1950s, Ninth Air Force units received the jet-powered F/RF-80 Shooting Star, F-84G/F Thunderjet, F-86D/H Sabre, and F-100 Super Sabre aircraft. Ninth Air Force squadrons and wings were frequently deployed to NATO during the
