The first production Fokker E.II..

The Fokker E.II was the second variant of the German Fokker Eindecker single-seat monoplane fighter aircraft of the First World War. The E.II was essentially a Fokker E.I with the 100-hp Oberursel U.I 9-cylinder rotary engine in place of the E.I's 80-hp Oberursel U.0. The E.II also had a larger fuel capacity, 145 lb (66 kg) to the E.Is 110 lb (50 kg), but otherwise the two types were hard to distinguish.

The E.II was built in parallel with the E.I and the choice of whether an airframe became an E.I or E.II depended on the availability of engines. In total, Fokker production figures state that 49 E.IIs were built. The last E.II was delivered in December 1915 when production switched to the main Eindecker variant, the Fokker E.III, which used the same 100-hp Oberursel U.I engine. Some E.IIs under production were completed as E.IIIs and numerous E.IIs returned to Fokker's factory for repair were upgraded to E.III specification.
