Design and development
editThe D.XI was designed by Reinhold Platz for Fokker and first flew on 23 March 1923. It was a single-seat sesquiplane (the lower wing was smaller than the upper) with a fixed tailskid landing gear. Due to financial problems, the Dutch government did not place an order, but 117 were built for export. There was some minor changes in design between customers, but all had the single-bay v-strut wing and powered by a 224 kW (300 hp) Hispano-Suiza piston engine. The twin radiators for the engine were mounted on the sides of the nose.
Operational history
editThe main customer was the USSR who operated the aircraft until 1929. The United States Army bought three aircraft for evaluation with the designation PW-7 and powered by a 328 kW (440 hp) Curtiss D.12. 50 aircraft on order for Germany were cancelled.
