[edit] Design and development

It was the world's first civilian plane with an all light metal internal skeletal frame. Tinplate was used for most of the skin, however. At the moment of production's start it was probably the most modern passenger plane in the world. Many variants were built using Mercedes, BMW, Junkers, Armstrong, Gnome-Rhône Jupiter, Pratt & Whitney Hornet engines.

[edit] Operational history

It flew with a Junkers airline until it merged with Lufthansa. Until 1922 the Junkers F13 was not allowed to operate in Germany due to the postwar restrictions. However 1919 and 1922 a number of airframes were sold to the USA (mostly to the US Post Office), France, England, Italy and Japan. In 1922/23, Hugo Junkers signed a contract with the Soviet Government to produce the aircraft in a Soviet factory . Several Junkers F 13 built there were used by the Red Army under the designation PS-3. A number of airframes also served in Soviet airlines. It saw active service until the 1940s, serving with many countries and being widely exported in many variants and a seaplane version. In China, Junkers F.13 was converted and used as a scout bomber and the last battle they participated in was the January 28 Incident during which the last surviving Junkers F.13s were destroyed along with the Shanghai Aircraft Factory>

The Colombian Air Force used the F-13 in the Colombia-Peru War in 1932-3.
