The Fokker D.VI was a German fighter aircraft with 59 built towards the end of World War I.
The D.VI served in the German and Austro-Hungarian air services.
In late 1917, Fokker-Flugzeugwerke built two small biplane prototypes designated V.13.
These aircraft combined a set of scaled-down D.VII wings with a fuselage and empennage closely mirroring those of the earlier Dr.I.
The first prototype utilized an 82 kW (110 hp) Oberursel Ur.II rotary engine, while the second featured a 119 kW (160 hp) Siemens-Halske Sh.III bi-rotary engine.
Fokker submitted both prototypes at the Adlershof fighter trials in late January 1918.
At that time, Fokker re-engined the first prototype with the 108 kW (145 hp) Oberursel Ur.III.
Pilots found the V.13s to be maneuverable and easy to fly.
Idflieg issued a production contract after the V.13s were ultimately judged to be the best rotary powered entries of the competition.
