The LFG Roland D.XVII was a single-seat, single-engine, parasol wing German fighter aircraft flown close to the end of World War I.

The structure was stabilized laterally with a further outward leaning strut between top of the forward V-strut and the upper fuselage.

The D.XVII was powered by a 138 kW (185 hp) BMW IIIa six cylinder, water-cooled inline engine driving a two-bladed propeller.

The fixed conventional undercarriage was standard for the time, with a rigid axle mounted to V-struts attached to the lower fuselage longerons, plus a tailskid faired into a small ventral fin.

[1][2] The D.XVII was rolled out on 18 October 1918 in time for the third D-type competition held at Adlershof that month but was judged inferior to the Fokker V 29, another parasol wing, BMW III powered design.
