The Junkers Ju 52/3m (nicknamed Tante Ju ("Aunt Ju" ) and Iron Annie) is a German trimotor transport aircraft manufactured from 1931 to 1952. Initially designed with a single engine but subsequently produced as a trimotor, it saw both civilian and military service during the 1930's and 1940's. In a civilian role, it flew with over twelve air carriers including Swissair and Deutsche Luft Hansa as an airliner and freight hauler. In a military role, it flew with the Luftwaffe as a troop and cargo transport and briefly as a medium bomber. The Ju 52 continued in postwar service with military and civilian air fleets well into the 1980's.
