The first Junkers Ju 52 was a single engined freighter, appearing in 1930. The more familiar trimotor Junkers Ju 52/3m appeared two years later, when large numbers were built for Lufthansa and foreign civil operators. They were first put to use by the new Luftwaffe as bombers when they formed the core of the heavy squadrons, and they were initially used in this role in the Spanish Civil War. However, with the arrival of more specialised bombing types, the Ju 52/3m was soon discarded as a bomber and turned into a military transport.
Although it was a “sitter” for fighters, and its losses were heavy, the Ju 52/3m was otherwise very successful in its new role and took part in invasions and advances by the Wehrmacht in many theatres of war, including Libya, Crete and the Low Countries. In April 1940 it figured in the first large-scale use of air transport in a war when it took part in the invasion of Norway. “Tante Ju”, as the Ju 52/3m was popularly known, remained in quantity production almost to the end of hostilities despite the emergence of several potential replacements.
Total production of the type, including a number built under licence in Spain and France, reached 4854 aircraft.
