Laon-Athies Air Base is an abandoned military airfield, which is located near the city of Laon in the Aisne department of France. Its history begins before World War II, when it was originally a grass civil airdrome. During the German occupation of France (1940–1944), the Luftwaffe developed the airdrome into a major military airfield, basing a variety of planes at the airfield, as well as using it as a maintenance and supply depot. Attacked frequently by Allied Air Forces, the Luftwaffe base was seized by Allied Ground Forces in September 1944 and was used as a Fighter and bomber base by the United States Army Air Forces until the end of the war.
