Pfalz D XV
Last of the Pfalz single-seaters was the D XV, which was officially type tested on 4th November 1918. It departed from previous practice in having the ply-skinned fuselage slung between the wings and all flying and landing wires deleted. The Inter-Allied Control Commission tabulation on the Pfalz-Werke credits 180 of these aircraft being built, but the figure seems not to have been substantiated. It seems likely that this was the number initially projected. Both 180 h.p. Mercedes D IIIa and 185 h.p. B.M.W. IIIa engined versions existed. Span, 8.6 m. (28 ft. 2 5/8 in.). Length, 6.5 m. (21 ft. 4 in.). Height, 2.7 m. (8 ft. 10 1/4 in.). Weights: Empty, 745 kg. (1,693 lb.), Merc; 738 kg. (1,624 lb.), B.M.W. Loaded, 925 kg. (2,035 lb.), Merc; 918 kg. (2,020 lb.), B.M.W. Speed, ca. 200 km.hr. (125 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 2 min., 6,000 m. (19,680 ft.) in 22.2 min. Armament, twin Spandau machine-guns.

PFALZ D XV Germany
Certainly one of the last, if not the last, single-seat fighter to be accepted for production in Germany during World War I - having completed its Typen-Prufung on 4 November 1918, a few days before the Armistice - the D XV participated in the third D-type Competition in October 1918. Departing from previous Pfalz practice in having the fuselage suspended between the single-bay wings and all flying and landing wires deleted, the D XV was developed during the summer of 1918, and flew in D XVf and D XV(Spezial) versions in the competition. The former had unbalanced ailerons and the latter had balanced ailerons which were adopted for the series version, both having the 185 hp BMW IIIa engine, although the Daimler D IIIa of 180 hp could also be fitted. The D XV was highly manoeuvrable and possessed a good performance, but was allegedly tail heavy and difficult to land. Too late to see operational service, several series D XVs were completed and Allied inspection teams found 74 finished D XV fuselages at the Pfalz Flugzeug-Werke in September 1919.
