Fighter Aircraft, First Flught 17 Sep 1917, 1 built
developed by Junkers + Co. in Dessau

Historical Background:

In July 1917 another design was developed by Junkers and Mader, named J7. Like the J3, also the J7 is developed without support of the German IDFLIEG. The J7 was directly based on the J3 design but also incorporated some of the J5 and J6 features. The first flight was performed on September, 17th 1917 by Arved von Schmidt. Following this first flight, the J7 underwent intensive modifications, especially regarding the flight controls and the engine section.

In February 1918 the J7 is tested by IDFLIEG at Adlershof and showed convenient performance and maneuvering features. In March 1918 IDFLIEG ordered three test aircraft of the J7. A further order for a serial production bench was depending on the further developement of Junkers' aircraft production facilities, as the J4 production line suffered massive delays at this time. Due to that request of IDFLIEG later on, the Junkers-Fokker Flugzeugwerke AG were founded to produce serial J7 aircraft.

Nevertheless, Hugo Junkers stopped the further developement of the J7 as well as the production of the three J7 test aircraft. The further developement work of this aircraft was done under the designator
Junkers J9. In sofar only a single aircraft was built under the designator J7, which was the world's first cantilever all light metal aircraft.
