L.F.G. Roland D XVI (first version)
  The penultimate Roland lighter was this D XVI parasol monoplane, which was doubtless inspired by the success of the Fokker E V/D VIII parasol. In reverse fashion to the Fokker machine, the Roland had a fabric-covered wing and a plywood-sheet-covered fuselage, the sheet being applied with the grain running diagonally. Engine, 160 h.p. Siemens-Halske Sh III geared rotary. Armament, twin Spandau machine-guns.

L.F.G. Roland D XVI (second version)
  In addition to having a different engine, the second D XVI prototype differed slightly in the shape of its vertical tail surfaces and in that the ply-sheet covering of the fuselage was no longer applied diagonally. Engine, 170 h.p. Goebel Goe III. Armament, twin Spandau machine-guns.

L.F.G. Roland D XVII
  Last of the long line of Roland lighters was this D XVII parasol monoplane. It utilised the same type of fuselage and engine installation as the B.M.W.-powered D XV prototype. Engine, 185 h.p. B.M.W. III. Armament, twin Spandau machine-guns.

LFG ROLAND D XVI Germany

  Two versions of the D XVI parasol monoplane fighter - initially designated E I - were completed in September-October 1918, one powered by a 160 hp Goebel Goe III rotary and the other by a similarly-rated Siemens-Halske Sh III rotary. The D XVI had a fully-cantilevered fabric-covered parasol wing and a slab-sided plywood-covered fuselage, armament comprising twin synchronised 7,9-mm LMG 08/15 machine guns. Although the 3rd D-type contest was officially restricted to types powered by the BMW engine, Idflieg permitted participation of the Sh III-engined D XVI as it was considered "an interesting type". The D XVI proved faster than the Siemens-Schuckert D IV and Fokker D VII up to an altitude of 13,125 ft (4 000 m), but was slower above that height.

Span 31 ft 0 1/2 in (9,46 m).
Length, 19 ft 4 in (5,90 m).


LFG ROLAND D XVII Germany

  The last single-seat fighter to be developed by LFG was the D XVII parasol monoplane powered by a 185 hp BMW IIIa engine. Rolled out on 18 October 1918, the D XVII was in time to be included in the 3rd D-type contest held at Adlershof that month, but was considered markedly inferior to the similarly-powered Fokker V 29 parasol monoplane. During turns the wing of the D XVII oscillated alarmingly and landing was difficult because of a tendency to stall suddenly during the approach if speed was not maintained. No further details are available.

Little in the way of hard fact appears to have survived concerning the pair of parasol-winged LFG Roland D XVIs of mid-1918, other than that they were powered by the 160hp Siemens-Halske Sh III or 170hp Goebels rotaries. Both were entered for the third of the 1918 fighter trials, held in October. This is the first example, the second machine having a taller fin and rudder.

Second to last Roland fighter was the experimental Type D.XVI. (160 h.p. eleven-cylinder Siemens-Halske Sh III engine.)
A Siemens-Halske Sh III engine distinguished the second of the two D XVI fighter prototypes.

Last of the Roland single-seat fighters, the D XVII was flown just before the end of World War I.

The last of a long line of LFG Roland fighters, their D XVII single seater was fitted with a 185hp BMW IIIa. Little reliable data survives on this machine, which is reported to have taken part in the second of the 1918 fighter trials. Note the position of the radiator, mounted to project forward of the wing centre section leading edge. This allowed the engine to be more smoothly cowled, but whether the radiator's position encroached upon the all-important fighter need for excellent forward pilot visibility is difficult to judge from this image.
