It was liberated by Allied ground forces about 27 August 1944 during the Northern France Campaign. Almost immediately, the USAAF IX Engineer Command 818th Engineer Aviation Battalion began clearing the base of mines and destroyed Luftwaffe aircraft; filling bomb craters in the runway with rubble and an asphalt patch along with repairing operational facilities for use by American aircraft. Subsequently, Villacoublay became a USAAF Ninth Air Force combat airfield, designated as "A-42" about 30 August, only a few days after its capture from German forces.[6]



Almost immediately, the 48th Fighter Group moved into the repaired air base, flying P-47 Thunderbolts from 29 August until 15 September 1944. The combat unit moved east along with the advancing Allied forces and Villacoublay became a supply and maintenance base for combat aircraft, becoming the home of the 370th Air Service Group and several Air Materiel squadrons from Air Technical Service Command. It was also given the designation of AAF-180. In addition, numerous C-47 Skytrain squadrons moved in and out, supporting airborne operations, including Operation Varsity, and Allied airborne crossing of the Rhine in March 1945.[7][8]



After the war ended, Villacoublay remained under American control, designated as AAF Station Villacoublay. It was assigned to the United States Air Forces in Europe as a transport base by the C-47 Skytrain-equipped 314th Troop Carrier Group. It remained under USAFE control until 31 August 1946 when it was returned to the French Air Force.[9]



From 1945[edit]



The base has been totally rebuilt since with war. The prewar/wartime runway, 11/29 is now closed and a new east-west 6000' (1800m) runway 09/27 laid down along with expanded aircraft parking areas and multiple hangars as part of an operational NATO air base.



After 1964 for a period, the base was the home to the Military Air Transport Command
