The Fokker V.17 and its derivatives were a series of experimental monoplane Fighter aircraft produced by the Dutch aircraft company Fokker in the 1910s.
V.20, was a cantilever mid-winged fighter with plywood covering and was powered by a 119kW (160hp) Mercedes D IIIa engine. It was similar to the V.17.
V.21 was much like the V.20 except the wings were tapered.
Fokker V.25
V.23 was related to the V.20 and V.21. It was evaluated by the German Army and rejected due to poor forward visibility (presumably on landing). The V.23 was powered by a 119kW (160hp) Mercedes III engine, was 5.8m (19ft) long, had a wingspan of 8.73m (28.64ft), a height of 2.65m (8.69ft). The wing area was 11.12m² (119.69ft²), the empty weight was 673kg (1,484lb), maximum weight 853kg (1,881lb). The maximum speed of the V.23 was 200km/h (124mph). Armament was two 7.92mm (.312in) machine guns.
V.25 was plywood-covered, with a low cantilever wing. It powered by an Oberursel Ur. II of 82kW (110hp). The aircraft was underpowered. V.25 was 5.93m (18.46ft) long, had a wing span of 8.73m (28.64ft) and was 2.63m (8.63ft) high. Its wing area was 11.12m² (119.69ft²), empty weight was 383kg (844lb), and had a maximum weight of 584kg (1,287lb).

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.II was the second variant of the German Fokker Eindecker single-seat monoplane fighter aircraft of World War I. The E.II was essentially a Fokker E.I with the 75 kW (100 hp) Oberursel U.I 9-cylinder rotary engine, a close copy of the French Gnôme Monosoupape rotary of the same power output, in place of the E.I's 60 kW (80 hp) Oberursel U.0, but whereas the E.I was simply a M.5K with a 7.92 mm (.312 in) machine gun bolted to it, the E.II was designed with the weapon system integrated with its airframe.
The Fokker E.IV was the final variant of the Eindecker fighter aircraft that was operated by Germany during World War I.
The RWD 3 was a 1930 Polish sports aircraft and liaison aircraft prototype, constructed by the RWD team, a single-engine high-wing monoplane.
The Fokker D.I was a development of the D.II fighter. The D.I was also flown in Austro-Hungarian service as a fighter trainer aircraft under the designation B.III. Confusing the matter further, both the D.II and D.I arrived at the Front in German service at similar times, in July–August 1916. The main designer was Martin Kreutzer.
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 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.
The Fokker M 10 was a two-seater reconnaissance / 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 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 Fokker F.II was the first of a long series of commercial aircraft from the Fokker Aircraft Company, flying in 1919. In a biplane age, it presented a distinct clean, high-wing monoplane style that sold successfully across Europe and North America during the development of commercial passenger-carrying aviation.
The Fokker S.IV was a military trainer aircraft produced in the Netherlands in the mid-1920s. It was a conventional, single-bay biplane with staggered wings of unequal span braced with N-struts, essentially a radial-engined development of the S.III. The pilot and instructor sat in tandem, open cockpits and the undercarriage was of fixed, tailskid type with a cross-axle between the main units. The Royal Netherlands Army Aviation Group purchased 30 examples and used them right up to the German invasion of the Netherlands in 1940. On 14 May that year, a few surviving S.IVs escaped to France alongside some S.IX trainers, but never flew again.
The PWS-21 was a Polish passenger aircraft for 4 passengers, built in PWS factory in 1930, that remained a prototype.
The PZL.4 was a Polish three-engine passenger aircraft for 10 passengers, built in PZL factory in 1932, which remained a prototype. It was the first Polish-designed and produced multi-engine plane.
The LFG Roland D.II was a German single-seat fighter of World War I. The type was manufactured by Luftfahrzeug Gesellschaft, and also by Pfalz Flugzeugwerke under license.
The RWD-16 was a Polish two-seat low-wing sports plane of 1936, constructed by the RWD team, that remained a prototype.
The Fokker PW-5 was a Dutch fighter aircraft of the 1920s. It was a parasol monoplane of which twelve were built for the US Army Air Service, being used as advanced trainers.
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 World War I Aeroplanes Fokker D.VII is an American homebuilt aircraft that was designed by Herbert Kelley and produced by World War I Aeroplanes Inc of Poughkeepsie, New York. When it was available the aircraft was supplied in the form of plans for amateur construction. The aircraft is a replica of the First World War Fokker D.VII fighter aircraft.
The NFW E.I was a prototype fighter aircraft built in Germany during World War I.
