The ACAZ C.2, Ateliers de Construction Aeronautique de Zeebruge, was a prototype Belgian biplane fighter aircraft built in the 1920s.
The Bristol F.2 Fighter is a British First World War two-seat biplane fighter and reconnaissance aircraft developed by Frank Barnwell at the British and Colonial Aeroplane Company later known as the Bristol Aeroplane Company. It is often simply called the Bristol Fighter, "Brisfit" or "Biff".
Between 1911 and 1914, the Royal Aircraft Factory used the F.E.2 designation for three quite different aircraft that shared only a common "Farman" pusher biplane layout.
The Royal Aircraft Factory S.E.5 is a British biplane fighter aircraft of the First World War. It was developed at the Royal Aircraft Factory by a team consisting of Henry Folland, John Kenworthy and Major Frank Goodden. It was one of the fastest aircraft of the war, while being both stable and relatively manoeuvrable. According to aviation author Robert Jackson, the S.E.5 was: "the nimble fighter that has since been described as the 'Spitfire of World War One'".
The Vickers F.B.5 was a British two-seat pusher military biplane of the First World War. Armed with a single .303 in (7.7 mm) Lewis gun operated by the observer in the front of the nacelle, it was the first aircraft purpose-built for air-to-air combat to see service, making it the world's first operational fighter aircraft.
The Sopwith 5F.1 Dolphin was a British fighter aircraft manufactured by the Sopwith Aviation Company. It was used by the Royal Flying Corps and its successor, the Royal Air Force, during the First World War. The Dolphin entered service on the Western Front in early 1918 and proved to be a formidable fighter. The aircraft was not retained in the postwar inventory and was retired shortly after the war.
The Vickers F.B.19 was a British single-seat fighting scout of the First World War, developed from the Barnwell Bullet prototype, and sometimes known as the Vickers Bullet. It served with the Royal Flying Corps and the Imperial Russian Air Service, which subsequently led to the Red Air Force adopting it during the Russian Civil War.
The Martinsyde G.100 "Elephant" and the G.102 were British fighter bomber aircraft of the First World War built by Martinsyde. The type gained the name "Elephant" from its relatively large size and lack of manoeuvrability. The G.102 differed from the G.100 only in having a more powerful engine.
The Royal Aircraft Factory B.E.12 was a British single-seat aeroplane of The First World War designed at the Royal Aircraft Factory. It was essentially a single-seat version of the B.E.2.
The Nieuport 12 was a French sesquiplane reconnaissance, fighter aircraft and trainer used by France, Russia, Great Britain and the United States during World War I. Later production examples were built as trainers and served widely until the late 1920s.
The Vickers F.B.14 was a British two-seat fighter/reconnaissance biplane designed and built by Vickers Limited. About 100 were built for the Royal Flying Corps but saw only limited use as it was designed for a larger engine which was not available when production commenced and it did not meet performance expectations.
The Avro 530 was a British two-seat fighter biplane designed in 1916 to compete with the Bristol F.2A. The plane was first flown in July 1917. It was of fabric-covered wooden construction, powered by a 200 hp (150 kW) Hispano-Suiza engine.
The Vickers F.B.12 was a biplane pusher fighter aircraft developed during World War I by Vickers Limited. The failure of the engine for which it was designed, and the obsolescence of the pusher configuration, resulted in its remaining an experimental type only.
The Morane-Saulnier BB was a military observation aircraft produced in France during World War I for use by Britain's Royal Flying Corps. It was a conventional single-bay biplane design with seating for the pilot and observer in tandem, open cockpits. The original order called for 150 aircraft powered by 110-hp Le Rhône 9J rotary engines, but shortages meant that most of the 94 aircraft eventually built were delivered with 80 hp Le Rhône 9C rotaries instead. A water-cooled Hispano-Suiza 8A engine was trialled as an alternative in the Type BH, but this remained experimental only. A production licence was sold to the Spanish company Compañía Española de Construcciones Aeronáuticas (CECA), which built twelve fitted with Hispano-Suiza engines in 1916.
The Vickers Type 123 was a 1920s British single-seat biplane fighter designed and built by Vickers Limited as a private venture. The only Type 123 was later modified into the Type 141 but, not winning any orders, it was scrapped in 1930.
The Royal Aircraft Factory N.E.1 was a prototype British night fighter of the First World War. A single-engined pusher biplane, it was a development of the Royal Aircraft Factory's earlier F.E.9 fighter, but was not successful, only six being built.
The Vickers F.B.16 was a British single-seat fighter aircraft of the First World War. It was originally designed to be powered by an experimental radial engine, development of which was abandoned. When re-engined with more powerful and reliable water-cooled V-8 engines, the F.B.16 demonstrated good performance, but only a few prototypes were built, the type not entering service.
The Vickers F.B.24 was a British two-seat fighter aircraft of the First World War. Only a few prototypes were built, as, although it had good performance, the Bristol F.2 Fighter was preferred.
The Vickers F.B.25 was a British two-seat night fighter prototype of World War I designed to attack enemy airships. Completed in 1917, it failed in its official flight tests that year and no order for production resulted.
The Wibault 12 Sirocco or Wib 12 Sirocco was a two-seat, parasol wing fighter aircraft designed and built in France in the 1920s. Three fighter prototypes were completed, one for the RAF and two Army co-operation variants. There was no series production.
