Despite the prohibition on military aircraft construction, German aviation firms continued to develop and produce planes for military needs. Testing often occurred either under the guise of civilian aircraft or in neutral countries, most frequently Denmark and Sweden.
Secret Development & Design
One such aircraft was the C.29 reconnaissance plane, developed by Caspar Werke AG in 1926. This two-seat biplane was equipped with a 500 hp Hispano-Suiza 12 Ga engine.
While armament was not installed, it was planned to include one forward and one rear (on a movable turret) 7.92mm machine gun.
Prototype and Fate
In 1926, the sole prototype of the aircraft was built at the factory of the Danish firm Dansk Aero. However, the project did not progress beyond testing, and the company shifted its focus to developing more advanced machines.
