The Fokker D.II was a German fighter biplane of World War I. It was a single seat fighter aircraft developed before the Fokker D.I. It was based on the M.17 prototype, with single-bay unstaggered wings and a larger fuselage and shorter span than production D.IIs. Using a 75 kW (100 hp) Oberursel U.I, the D.II was underpowered, though the single 7.92 mm (.312 in) lMG 08machine gun was normal for 1916. The German Army purchased 177.
In service, the D.II proved to be little better than the earlier Fokker Eindecker fighters - in particular, it was outclassed by the Nieuport 11 and 17. A few examples were used by the Kampfeinsitzerkommandos and the early Jagdstaffeln alongside the Halberstadt D.II but the early Fokker biplanes were quickly discarded when the new Albatros fighters came out.
