O.Thetford, P.Gray German Aircraft of the First World War (Putnam)

L.F.G. Roland D XIII
   Next in the long series of Roland prototypes was the D XIII serialled 3002/18, there being no record of D X, XI or XII. This was little more than the second version of the D VII with a 195 h.p. Korting vee-eight engine with reduction gearing. Span, 9 0 m. (29 ft. 6 3/8 in.). Area, 23 sq.m. (248 sq.ft.). Armament, twin Spandau machine-guns.

L.F.G. Roland D XV (first version)
   As the first of four D XV prototypes, No. 3004/18 still perpetuated the use of clinker-built fuselage first used on the D IV. The wings had no bracing cables and considerably more stagger than any of the previous prototypes which probably improved forward and downward visibility from the cockpit, but omission of centre-section cut-out could not have given very good upward and forward field of view. Engine, 160 h.p. Mercedes D III. Span, 8.64 m. (28 ft. 4 1/4 in.). Area, 23.8 sq.m. (257 sq.ft.). Weights: Empty, 730 kg. (1,606 lb.). Loaded, 910 kg. (2,002 lb.). Armament, twin Spandau machine-guns.

L.F.G. Roland D XV (second version)
   The second D XV prototype. No. 3006/18, was basically a D VI airframe with a new wing cellule braced solely with single I-struts, no cables being used. The top wing was of greater chord while the chord of the lower wing was considerably reduced. This was the last of the Roland fighter series to feature the clinker-planked fuselage. Engine, 180 h.p. Mercedes D IIIa. Span, 9.0 m. (29 ft. 6 3/8 in.). Area, 23 sq.m. (248 sq.ft.). Armament, twin Spandau machine-guns.

L.F.G. Roland D XV (third version)
   The third and fourth versions of the D XV were alike except for engine installation. In construction they were very different to their precursors, slab-sided plywood-covered fuselages being used and the wings braced with tubular steel "N" struts. There were no flying or landing wires bracing the wing cellule. This model is said to have been a copy of the Fokker D VII, which may or may not be true. Certainly it was no slavish although a certain similarity of outline must be admitted. Engine, 185 h.p. B.M.W. III (third version), 200 h.p. Benz Bz IIIa V (fourth version). Armament, twin Spandau machine-guns.
