The Roland D.VI was a German fighter aircraft built at the end of World War I. It lost a fly-off to the Fokker D.VII, but production went ahead anyway as insurance against problems with the Fokker. A total of 350 were built, 150 D.VIas powered by an inline six cylinder Mercedes engine, while the remaining 200 were powered by a similar engine from Benz and were called D.VIb. Deliveries started in May 1918, with 70 D.VIs in frontline service on 31 August 1918.
