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.

Pfalz D.XV

  The Pfalz D.XV was the ultimate Pfalz fighter design. The new design was clearly evolved from the D.XII, yet was strongly influenced by the exceptional Fokker D.VII. The D.XV wings were thicker than previous Pfalz designs, although not as thick as Fokker D.VII wings, and featured single bays. Early prototypes had minimum wire bracing, but the design was finally developed through a number of prototypes to a wireless wing like the Fokker D.VII.
  The production Pfalz D.XV was a fast, maneuverable fighter that the Germans considered the equal of the Fokker D.VII, which was high praise considering the Fokker D.VII was probably the best operational fighter of WWI. Powered, like the best D.VIIs, by the 185 hp BMW D.IIIa engine, the D.XV demonstrated an excellent climb rate. Production started in October 1918, and the Typenprufung was formally completed on November 4, 1918, a week before the Great War ended. Apparently some production aircraft reached supply depots [flugparks) before the war ended, but had not been delivered to operational units.
  The Austro-Hungarian Luftfahrtruppe was also interested in the Pfalz D.XV and planned license production,- these plans were cancelled with the armistice. When the war ended, so did Pfalz's chance to finally step from the shadow of Fokker and make a solid reputation for itself with the excellent Pfalz D.XV.

J.Herris - Development of German Warplanes in WWI /Centennial Perspective/
Production Pfalz D.XV in factory finish. The D.XV was at the flugparks the last week of the war but did not reach combat. For the D.XV Pfalz had worked hard to eliminate the bracing wires of the D.XII for improved speed and climb and reduced maintenance. The D.XV accomplished those goals and was considered the equal in performance, maneuverability, and flying characteristics of the famous D.VII, but never had the opportunity to prove itself. It was forgotten and after the war Pfalz went bankrupt. Power was the 185 hp BMW.IIIa engine.

Pfalz D.XVf 8364/17, which took part in the Third Fighter Competition in October 1918, was obviously camouflaged in the same manner as many of the production D.XII machines. It is conjecturally illustrated in the 'Canberra' pattern of D.XII colors. These sprayed colors were wrapped entirely around the fuselage. The cabane struts appear to have been a dark color, the rest a light silver-gray or blue. The wings and tailplane were in five-color fabric.

Pfalz D.XV originally owned by Ernst Udet shown in the markings of its second owner, Max Holtzem, while barnstorming in Argentina. The aircraft was red overall with white lettering and the rudder was in the blue/white/blue Argentine national colors.

A production Pfalz D.XV at Adlershof during type-testing. Production D.XVs had the 185 hp BMW D.IIIa engine, which used a pointed propeller spinner as seen here. There is no interplane bracing, which eliminated significant drag, and the ailerons have horn balances.
The Pfalz D.XV, finally with the 185 hp BMW.IIIa engine the Pfalz D.XII had needed to reach its full potential, was an excellent fighter developed from the D.XII. It was as fast and maneuverable as the Fokker D.VII, and the first examples arrived at the Army Flugparks the last week of the war. Just missing combat, it was forgotten in the aftermath, as was the Pfalz company, which went bankrupt soon after the war ended.

Pfalz D.XV given to Ernst Udet by Pfalz in 1919. Together with his friend Robert Ritter von Greim, like Udet a fighter ace and recipient of the Pour Le Merite, they obtained some Fokker D.VIIs and D.VIIIs from a factory in Bamberg. Udet had his three aircraft painted bright red, and the two put on a series of flying displays and mock combats in Bavaria. Later they acquired some Rumpler D.Is. Because of the Treaty of Versailles, their flying displays came to an end and Udet sold his Pfalz D.XV to former Jasta 16b pilot Max Holtzem. Holtzem took the Pfalz D.XV to Argentina, where he became a well-known stunt pilot. Captions on the original photos stated that Udet was making a world-record height attempt in the D.XV, but nothing is known about this.

Pfalz D.XV flown by Max Holtzem for barnstorming in Argentina post-war. He added a second cockpit to the D.XV so he could give rides. Holtzem, an excellent pilot, had a long association with Pfalz, being a Pfalz acceptance test pilot and flying the D.IIIa with Jasta 16b. He claimed several unconfirmed victories. Streamlined I-struts were eliminated during D.XV development because they interferred with the pilot's view during combat. Eliminating the integral fin facilitated production.
