Fokker V.17

The Fokker V.17 and its derivatives were a series of experimental monoplane fighters produced by Fokker in the 1910s. The V.17 was a shoulder cantilever-winged monoplane with plywood covering and an 82 kW Oberursel engine. The V.20 was a cantilever mid-winged fighter with plywood covering, powered by a 119 kW Mercedes D IIIa engine, and similar to the V.17, while the V.21 was much like the V.20 except that its wings were tapered. The V.23 was related to the V.20 and V.21 and was evaluated by the German Army, which rejected it because of poor forward visibility. It had a 119 kW Mercedes engine, a length of 5.8 m, a wingspan of 8.73 m, a height of 2.65 m, a wing area of 11.12 square metres, an empty weight of 673 kg, a maximum weight of 853 kg and a maximum speed of 200 km/h.
