The Sopwith Pup is a British single-seater biplane fighter aircraft built by the Sopwith Aviation Company. It entered service with the Royal Naval Air Service and the Royal Flying Corps in the autumn of 1916. With pleasant flying characteristics and good manoeuvrability, the aircraft proved very successful. The Pup was eventually outclassed by newer German fighters, but it was not completely replaced on the Western Front until the end of 1917. Remaining Pups were relegated to Home Defence and training units. The Pup's docile flying characteristics also made it ideal for use in aircraft carrier deck landing and takeoff experiments and training.
The Nieuport 17 C.1 was a French sesquiplane fighter designed and manufactured by the Nieuport company during World War I. An improvement over the Nieuport 11, it was a little larger than earlier Nieuports and better adapted to the more powerful engine than the interim Nieuport 16. Aside from early examples, it had the new Alkan-Hamy synchronization gear, permitting the use of a fuselage-mounted synchronised Vickers gun firing through the propeller disc.
The Avro 504 was a First World War biplane aircraft made by the Avro aircraft company and under licence by others. Production during the war totalled 8,970 and continued for almost 20 years, making it the most-produced aircraft of any kind that served in any military capacity during the First World War. More than 10,000 were built from 1913 until production ended in 1932.
The Airco DH.2 was a single-seat pusher biplane fighter aircraft which operated during the First World War. It was the second pusher design by aeronautical engineer Geoffrey de Havilland for Airco, based on his earlier DH.1 two-seater.
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 Sopwith 1+1⁄2 Strutter was a British single- or two-seat multi-role biplane aircraft of the First World War. It was the first British two-seat tractor fighter and the first British aircraft to enter service with a synchronised machine gun. It was given the name 1+1⁄2 Strutter because of the long and short cabane struts that supported the top wing. The type was operated by both British air services and was in widespread but lacklustre service with the French Aéronautique Militaire.
The Morane-Saulnier Type P was a French parasol wing two-seat reconnaissance aeroplane of the First World War. Morane-Saulnier built 595 for the French air force, and it was also used by the British until 1916-17.
The Nieuport 27 was a World War I French sesquiplane fighter aircraft designed by Gustave Delage. The 27 was the last of the line of Nieuport "V-strut" single seat fighters that began with the Nieuport 10 of 1914. Operational examples supplemented the very similar Nieuport 24 and 24bis in operational squadrons in late 1917 and many would also be used as advanced trainers.
The Bristol Scout was a single-seat rotary-engined biplane originally designed as a racing aircraft. Like similar fast, light aircraft of the period it was used by the RNAS and the RFC as a "scout", or fast reconnaissance type. It was one of the first single-seaters to be used as a fighter aircraft, although it was not possible to fit it with an effective forward-firing armament until the first British-designed gun synchronizers became available later in 1916, by which time the Scout was obsolescent. Single-seat fighters continued to be called "scouts" in British usage into the early 1920s.
The Armstrong Whitworth F.K.3 was a British two-seat general-purpose biplane built by Armstrong Whitworth Aircraft during the First World War. By the end of the war it was considered obsolete for combat.
The Armstrong Whitworth F.K.8 was a British two-seat general-purpose biplane built by Armstrong Whitworth during the First World War. The type served alongside the better known R.E.8 until the end of the war, at which point 694 F.K.8s remained on RAF charge.
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 Armstrong Whitworth F.K.10 was a British two-seat quadruplane fighter aircraft built by Armstrong Whitworth during the First World War. While it was ordered in small numbers for the Royal Flying Corps and Royal Naval Air Service, it was not used operationally. It is one of the few quadruplane aircraft to reach production.
The Bristol M.1 Monoplane Scout was a British monoplane fighter of the First World War. It holds the distinction of being the only British monoplane fighter to reach production during the conflict.
The Royal Aircraft Factory F.E.8 was a British single-seat fighter of the First World War designed at the Royal Aircraft Factory. It could not escape the drag penalty imposed by its tail structure and was no match for the Albatros fighters of late 1916.
The Nieuport 24 was a World War I French sesquiplane fighter aircraft designed by Gustave Delage as a development of the successful Nieuport 17.
The Farman HF.20 and its derivatives were a family of reconnaissance aircraft produced in France shortly before and during the First World War. It was a refined version of the Farman MF.11 "Shorthorn" that did away with the type's distinctive landing skids, and incorporated design features from Henri Farman's designs. It entered service with the French, Belgian and Serbian armies in 1913, and with the British RFC and RNAS shortly after the outbreak of war. The type was also licence-built in the UK by Airco and Grahame-White.
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 Nieuport 16 C.1 was a French World War I single-seat sesquiplane fighter aircraft, designed by Gustave Delage as a development of the Nieuport 11 with a more powerful engine. The Nieuport 16's service life coincided with the period when the first air-to-air rockets, the Le Prieur rocket, were used most frequently, and the type has a closer association with them than any other aircraft.
The Nieuport 17bis C.1 was a World War I French single-seat sesquiplane fighter that was produced under licence in the United Kingdom in small numbers for the Royal Naval Air Service.
