Juvincourt Airfield is an abandoned military airfield, which is located near the commune of Juvincourt-et-Damary in the Aisne department of northern France. Built originally as a grass airfield by the French Air Force before World War II, Juvincourt was expanded to become one of the main German Luftwaffe air bases in France during the German occupation (1940–1944), hosting a wide variety of both fighter and bomber aircraft, including German jet fighters and bombers. Seized by the Allies in September 1944, it became a major United States Army Air Forces base for fighter, bomber and transport units for the remainder of the European War (1944–1945).
