Another example of Fokker’s slow evolutionary pace. The company kept producing aircraft with plywood wings with a steel tube fuselages, all fabric covered for too long. It was cheap and that was the main factor for its retention.
Designed originally to answer an Dutch East Indian Army order, the few D.XVII (11) built were instead delivered to the Netherlands Air Corps. A curiosity was they were powered by a plethora of engines: Curtiss Conqueror, RR Kestrel, Hispano-Suiza, Lorraine-Dietrich… and that, remember, for only twelve (11+prototype) produced.
Declared obsolete at 1939, the few still in service at the time of surrender were sadly burned.
In this cool sepia photo a splendid RR Kestrel engined example.
