The Descamps 27 C1 was a single seat biplane fighter aircraft, built in France in 1919. It was unusual in having a forward swept lower wing. After competitive trials, the Nieuport 29 was chosen for production, so only one Descamps was built.
The Descamps 27 was a two bay biplane. Its upper and lower wings had the same constant chord and the same spans when the overhangs of the balanced ailerons, fitted only to the lower wing, were included. There was forward stagger, so each pair of parallel interplane struts leant forward. The upper wing was unswept but the lower wing had about 7° of forward sweep to improve the pilot's forward and downwards field of view. As a result, the inner interplane strut pairs leant forward more strongly. Short cabane struts held the centre of the upper wing a little above the fuselage; the pilot's open cockpit was under the trailing edge, where there was a shallow cut-out to improve his upward view. [1]
The fighter was powered by a 220 kW (300 hp) Hispano-Suiza 8Fb water-cooled V-8 engine in a round-profiled nose with a large, domed spinner. A pair of forward firing, synchronised 7.7 mm (0.303 in) machine guns were within the cowling above the engine. Behind the engine the fuselage was flat sided, though with rounded top and bottom. A shallow rectangular radiator was fixed against the fuselage on either side of the cockpit. The Descamps' tailplane, which was mounted on top of the fuselage, was small compared with the balanced elevators; together they shared a semi-circular leading edge and a swept trailing edge. The fin was also relatively small compared with the rudder, which was rounded, deep and extended to the keel; it operated in an elevator cut-out. [1]
The landing gear of the Descamps 27 was of the conventional tailskid type. Its mainwheels were on a single axle and fixed to the lower fuselage by a pair of V-form struts. [1]
The Descamps 27 performed well in government comparative trials of it and other single seat fighters but the Nieuport 29 was preferred and went into production. Development of the Descamps machine ended and only one was built. [1]

Armament
The Fokker D.IX was a Dutch single seat, single engine fighter aircraft, the final, more powerful evolution of the Fokker D.VII World War I success, flown in 1921. The sole example was purchased by the US Army Air Service but not developed further.
The Nieuport-Delage NiD 37 was a single-engine, single-seat monoplane fighter aircraft and racer designed and built in France in the early 1920s. It had a small foreplane to bring the centre of pressure forward. Heavy, slower than expected and with turbo-supercharger problems, development ended without any entering service.
The Nieuport-Delage NiD 43 was a single-engine, two-seat biplane fighter aircraft designed and built for shipboard use in France in 1924.
The Nieuport-Delage NiD 48 was a French single-engine parasol wing light fighter aircraft, designed and built in the 1920s. Its performance was not markedly better than that of the much heavier Nieuport-Delage NiD 62 then going into production, so only two were flown.
The Wibault Wib 1, Wib C1 or, later, Wib 1 C1 was a French World War I single seat, single engine fighter aircraft prototype. Flown near the end of the war, it was not selected for production.
The Wibault 3 or Wibault Wib 3 C.1 was a French parasol wing prototype fighter aircraft from the 1920s, designed for high altitude operations. Its development was abandoned after repeated materials failure in its supercharger.
The Letov Š-7 was a single-seat, single-engine biplane fighter aircraft designed and built in Czechoslovakia in the early 1920s. It was designed for a single-seat fighter competition but did not reach production.
The Letov Š-13 was a single-seat, single-engine fighter aircraft designed and built in Czechoslovakia in the early 1920s. A biplane, it had aerodynamically thick wings which were originally cantilever structures, though interplane struts were later added. Only one was produced.
The Letov Š-14 was a single-seat, single-engine aircraft, designed and built in Czechoslovakia in the early 1920s. Originally intended as a biplane fighter, it was later modified into a monoplane and entered as a contestant in a speed competition.
The Letov Š-22 was a single-seat, single-engine aircraft designed and built in Czechoslovakia in the mid-1920s. A parasol-wing Dewoitine-style fighter, it was not successful, and only one was built.
The Dewoitine D.15 was a single-engine, single-seat biplane fighter aircraft built in France in the 1920s. Intended to offer structural simplifications when compared with monoplanes, it had a disappointing performance and was soon abandoned.
The Hanriot HD.5 was a French two-seat fighter aircraft prototype, built towards the end of World War I. A single-engine biplane with an unusually narrow gap between the upper and lower wings, it did not enter production.
The Hanriot HD.15 was a French two seat fighter aircraft fitted with a supercharger for good high altitude performance, built in the 1920s. Three were ordered by Japan but lost at sea during delivery.
The Hanriot HD.20 was a French single seat shipboard fighter aircraft prototype completed in 1923. Only one was built.
The FVM J 23 was a Swedish single seat, single engine, parasol wing fighter aircraft built in the mid-1920s. Five were flown but the type never reached operational status because of structural concerns raised by a fatal accident.
The Caudron C.74 was a ten-seat, four engine passenger biplane built in France in 1922. It showed promise but the sole prototype crashed fatally in a competition and no more were completed.
The de Marçay 2 C1 was a prototype single-seat biplane fighter designed in France and first flown in 1919. It did not go into production.
The de Marçay 4 was a single seat monoplane fighter built in France in 1923 for a government competition. It did not receive a production contract.
The Villiers V, Villiers 5 or Villiers 5CN2 was a French night fighter built in the mid-1920s. It did not go into production.
The Villiers VIII or 8amC1 was a French shipboard fighter capable of alighting on water. After competitive tests, it did not receive a production order.
