Fokker E.II

The Fokker E.II was the second variant of the German Fokker Eindecker single-seat monoplane fighter aircraft of World War I. The E.II was essentially a Fokker E.I with the 75 kW Oberursel U.I 9-cylinder rotary engine, a close copy of the French Gnôme Monosoupape rotary of the same power output, in place of the E.I's 60 kW Oberursel U.0, but whereas the E.I was simply a M.5K with a 7.92 mm machine gun bolted to it, the E.II was designed with the weapon system integrated with its airframe.
