Fokker D.X

Developed at Schwerin from the V.41, the partly-completed single-seat fighter prototype was taken to the Netherlands, where, in 1921, it was completed with a 300hp Hispano-Suiza 8Fb eight-cylinder water-cooled engine in place of the 185hp BMW Ilia six-cylinder engine for which it had been originally intended.

A cantilever parasol monoplane with a plywood-skinned wooden wing and a steel-tube fuselage, the prototype crashed as a result of wing flutter during a demonstration in Spain in 1922. An order for 10 D X fighters was placed on behalf of the Aeronautica Militar Espanola, these being supplied during the course of 1923. In the same year, one example of the D X was supplied to Finland. Armament comprised two 7.92mm machine guns.
