Stavanger Airport, Forus (Norwegian: Stavanger lufthavn, Forus: ICAO: ENFO) is a former airport located at Forus in the intersection of the municipalities of Stavanger, Sola and Sandnes. It was built as a military air base by the Luftwaffe following the German occupation of Norway in April 1940. It was gradually expanded so that it by 1943 consisted of three runways, the longest 1,950 meters (6,400 ft). The airfield was connected by a 3.6-kilometer (2.2 mi) taxiway to Sola Air Station. The airport served as an offensive base during the Battle of Britain, and was afterwards made part of the defensive Festung Norwegen.
