The Fokker D.VI was a German fighter aircraft built in limited numbers at the end of World War I. The D.VI served in the German and Austro-Hungarian air services.
In late 1917, Fokker-Flugzeugwerke built two small biplane prototypes designated V.13. These aircraft combined a set of scaled-down D.VII wings with a fuselage and empennage closely mirroring those of the earlier Dr.I. [1] The first prototype utilized an 82 kW (110 hp) Oberursel Ur.II rotary engine, while the second featured a 119 kW (160 hp) Siemens-Halske Sh.III bi-rotary engine. [2]
Fokker submitted both prototypes at the Adlershof fighter trials in late January 1918. [3] At that time, Fokker reengined the first prototype with the 108 kW (145 hp) Oberursel Ur.III. [3] Pilots found the V.13s to be maneuverable and easy to fly. [4] Idflieg issued a production contract after the V.13s were ultimately judged to be the best rotary powered entries of the competition. [4]
The new aircraft, designated D.VI, passed its Typenprüfung (official type test) on 15 March 1918. [5] The production aircraft utilized the Oberursel Ur.II, which was the only readily available German rotary engine. Idflieg authorized low level production pending availability of the more powerful Goebel Goe.III. [5] Deliveries commenced in April and ceased in August, after only 59 aircraft had been completed. [6] Seven aircraft were delivered to the Austro-Hungarian Air Service (Luftfahrtruppen).
In service, the D.VI was hampered by the low power of the Oberursel Ur.II. [5] Moreover, the lack of castor oil and the poor quality of "Voltol," an ersatz lubricant, severely reduced engine life and reliability. [1] The D.VI remained in frontline service until September 1918, and continued to serve in training and home defense units until the Armistice.

The Fokker Dr.I, often known simply as the Fokker Triplane, was a World War I fighter aircraft built by Fokker-Flugzeugwerke. The Dr.I saw widespread service in the spring of 1918. It became famous as the aircraft in which Manfred von Richthofen gained his last 17 victories, and in which he was killed on 21 April 1918.
The Fokker E.V was a German parasol-monoplane fighter aircraft designed by Reinhold Platz and built by Fokker-Flugzeugwerke. The E.V was the last Fokker design to become operational with the Luftstreitkräfte, entering service in the last months of World War I. After several fatal accidents due to wing failures, the aircraft was modified and redesignated Fokker D.VIII. Dubbed the Flying Razor by post-war pulp-fiction writers, the D.VIII had the distinction of scoring the last aerial victory of the war.
The Fokker E.III was the main variant of the Eindecker fighter aircraft of World War I. It entered service on the Western Front in December 1915 and was also supplied to Austria-Hungary and Turkey.
Motorenfabrik Oberursel A.G. was a German manufacturer of automobile, locomotive and aircraft engines situated in Oberursel (Taunus), near Frankfurt (Main), Germany. During World War I it supplied a major 100 hp-class rotary engine that was used in a number of early-war fighter aircraft designs. In 1921 the company merged with Deutz AG, and then again in 1930 with Humboldt-Deutz Motoren, and finally in 1938 with Klöcknerwerke AG. From this point on they were known as the Klöckner-Humboldt-Deutz Oberursel factory, known primarily for their locomotive engines. Today they are part of Rolls-Royce Deutschland, and produce one family of their jet engines.
The Siemens-Schuckert D.IV was a late-World War I fighter aircraft from Siemens-Schuckert (SSW). It reached service too late and was produced in too few numbers to have any effect on the war effort.
The Pfalz D.XII was a German fighter aircraft built by Pfalz Flugzeugwerke. Designed by Rudolph Gehringer as a successor to the Pfalz D.III, the D.XII entered service in significant numbers near the end of the First World War. It was the last Pfalz aircraft to see widespread service. Though the D.XII was an effective fighter aircraft, it was overshadowed by the highly successful Fokker D.VII.
The Pfalz D.VIII was a German World War I fighter aircraft.
The Fokker V.1 was a small German sesquiplane experimental fighter prototype built in 1916 by the Fokker-Flugzeugwerke. Sporting a parasol wing, it was the first Fokker aircraft purportedly designed by Reinhold Platz—the respective roles played by Fokker himself, Platz, and possibly others in the conceptual design of Fokker airplanes are a matter of dispute among historians—and was an early experiment in cantilever wing construction, eliminating the bracing wires typical of aircraft design at the time, something that had already been achieved with metal materials in Hugo Junkers' own pioneering Junkers J 1 in 1915.
The Fokker M.7 was a German observation aircraft of World War I, used by the armed forces of both Germany and Austro-Hungary.
The Fokker M 10 was a two-seater reconnaissance / fighter-trainer biplane with single-bay wings equipped with wing-warping controls for roll, powered by a 7-cylinder 80 hp Oberursel U.0 engine. Several M 10 aircraft were purchased by the Imperial and Royal Aviation Troops of Austro Hungary.
The Fokker D.III was a German single-seat fighter aircraft of World War I. It saw limited frontline service before being withdrawn from combat in December 1916.
The Fokker D.V was a German biplane fighter of World War I.
The Siemens-Schuckert D.III was a German single-seat fighter built by Siemens-Schuckert Werke. The D.III was a development of the earlier Siemens-Schuckert D.IIc prototype. The D.III was an (nearly) equal-span biplane powered by a 160 hp (119 kW) Siemens-Halske Sh.III bi-rotary engine. Idflieg placed an order for 20 aircraft in December 1917, followed by a second order of 30 aircraft in February 1918.
The Roland D.VI was a German fighter aircraft built at the end of World War I. It lost a fly-off to the Fokker D.VII, but production went ahead anyway as insurance against problems with the Fokker.
The Siemens-Schuckert E.I was a German fighter aircraft, manufactured by Siemens-Schuckert.
The Siemens-Schuckert D.VI was a single engine, single seat, parasol wing German fighter aircraft flown in 1919.
The Kondor E 3, sometimes erroneously known as E.III, was a German single seat, monoplane fighter aircraft designed and built close to the end of World War I. Though successful in the third D-type fighter competition at Aldershof in September 1918, only a few were produced, given the Idflieg designation of Kondor D.I.
The LFG Roland D.IX was a World War I German single seat fighter aircraft, a biplane powered by one of a new generation of powerful rotary engines. Three slightly different prototypes were built but there was no series production.
The LFG Roland D.XVI, initially designated the LFG Roland E.I, was a single-seat, single-engine, parasol wing German fighter aircraft flown close to the end of World War I. Only two were built.
The Kondor D 2 was a German single seat, biplane fighter aircraft designed and built close to the end of World War I.
