Mohamed Boudiaf International Airport (IATA: CZL, ICAO: DABC), also known as Mohamed Boudiaf Airport, is an airport in Algeria, located approximately 9 km south of Constantine; about 320 km east-southeast of Algiers.
The airport has been given the name of President Mohamed Boudiaf. Muhammad Boudiaf (June 23, 1919 – June 29, 1992) (Arabic: محمد بوضياف), also called Si Tayeb el Watani, was an Algerian political leader and one of the founders of the revolutionary National Liberation Front (FLN) that led the Algerian War of Independence (1954–1962).
The airport was built in 1943 as Constantine Airfield by the United States Army during the World War IINorth African Campaign. It was primarily a maintenance and supply depot for Air Technical Service Command and also served as headquarters for XII Bomber Command as a command and control base. It also was used as a command post for Allied Forces Command (AFHQ) for Free French, British and United States ground forces in Algeria in February 1943, under the command of General Sir Harold R. L. G. Alexander to coordinate the actions of the United States First Army advancing from the west and the British Eighth Army, advancing from the east against the German Afrika Korps. In 1944 it was turned over to the Algerian government and used occasionally by Air Transport Command aircraft on the North African route until the end of the war.
