Fokker D.VI

The Fokker D.VI was a German biplane fighter built in limited numbers at the end of World War I and flown by both the German and Austro-Hungarian air services. It grew out of two small V.13 prototypes that combined scaled-down D.VII wings with a fuselage and tail closely mirroring the Dr.I, and which Idflieg judged the best rotary-powered entries of the Adlershof trials in January 1918. The D.VI passed its official type test on 15 March 1918. Deliveries ran from April to August with only 59 completed, seven of them for Austria-Hungary. The low power of its Oberursel Ur.II engine and poor ersatz lubricant limited it, and it stayed in frontline service until September 1918.
