F.13


First flown on June 25, 1919 (as the J 13), the Junkers F 13 was the first airworthy all-metal commercial aircraft. Entering service in 1919, it carried only four passengers, albeit in a comfortable cabin - even fitted with seatbelts, then rare - the F 13 played a major role in the development of air transport, particularly in Europe and South America.

Negotiations by the new Soviet government for the produc-tion of Junkers aircraft in Russia were started in 1919; they resulted in German assembly in Russia of the F.13 transport from German manufactured parts.


Deutsche Luft Hansa was a significant purchaser (of 72 examples).


Estimates of total production vary between 318 and 370, over a decade of production, and there were more than 60 variations of the basic design built up to 1932. The seaplane version was fitted with larger wings than the land based version.


After the F13, Junkers was forced to stop work on an advanced cantilever wing monoplane transport because of the restrictions on the performance of German airplanes.


One was still active in Brazil as late as 1952.

 

Junk-F13

 

In 1919 John M. Larsen intended to sell U.S. aircraft in Denmark, but during his stay in Europe he also saw the Junkers F13 and was interested in selling the Junkers F13 within the USA. Together with Junkers he founded the Junkers Larsen Corporation in 1920, which was responsible for the marketing of Junkers aircraft in the USA. Larsen managed to sell some of the modified F13 as JL6 to the U.S. Army and to the U.S. Postal Office. But due to a series of crashes the JL6 was grounded by both. Larsen also converted one JL6 to a war machine as JL12, but the U.S. Army was not interested in this aircraft and the joint venture was stopped after a few sales, in 1920.
