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. The 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.
Nieuport, later Nieuport-Delage, was a French aeroplane company that primarily built racing aircraft before World War I and fighter aircraft during World War I and between the wars.
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 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.
The SPAD S.VII was the first of a series of highly successful biplane fighter aircraft produced by Société Pour L'Aviation et ses Dérivés (SPAD) during the First World War. Like its successors, the S.VII was renowned as a sturdy and rugged aircraft with good climbing and diving characteristics. It was also a stable gun platform, although pilots used to the more manoeuvrable Nieuport fighters found it heavy on the controls. It was flown by a number of the famous aces, such as France's Georges Guynemer, Italy's Francesco Baracca and Australia's Alexander Pentland.
The Nieuport 11, nicknamed the Bébé, is a French World War I single seat sesquiplane fighter aircraft, designed by Gustave Delage. It was the primary aircraft that ended the Fokker Scourge in 1916. The type saw service with several of France's allies, and gave rise to the series of "vee-strut" Nieuport fighters that remained in service into the 1920s.
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 Nieuport 10 was a French First World War sesquiplane that filled a wide variety of roles, including reconnaissance, fighter and trainer.
The Le Rhône 9J is a nine-cylinder rotary aircraft engine produced in France by Gnome et Rhône. Also known as the Le Rhône 110 hp in a reference to its nominal power rating, the engine was fitted to a number of military aircraft types of the First World War. Le Rhône 9J engines were produced under license in Great Britain by W.H. Allen Son & Company of Bedford, and in Germany by Motorenfabrik Oberursel where it was sold as the Oberursel Ur.II.
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 Nieuport 24 was a World War I French sesquiplane fighter aircraft designed by Gustave Delage as a development of the successful Nieuport 17.
The Clerget 9B was a nine-cylinder rotary aircraft engine of the World War I era designed by Pierre Clerget. Manufactured in both France and Great Britain, it was used on such aircraft as the Sopwith Camel. The Clerget 9Bf was an increased stroke version.
The SPAD S.A was a French two-seat tractor biplane first flown in 1915. It was used by France and Russia in the early stages of the First World War in the fighter and reconnaissance roles. It was a unique aircraft that carried its observer in a nacelle ahead of wing, engine and propeller.
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 Nie 31 or Nieuport 31 was a single-engine, single-seat monoplane or sesquiplane fighter aircraft designed and built in France in 1919.
In October 1917 Nieuport began construction of a prototype monoplane fighter known as the Nieuport Madon, a strut braced monoplane.
The Audenis C2 was a two-seat fighter biplane, designed and built in France during 1916. Probably powered by a 130 hp (97 kW) Clerget 9B 9-cylinder rotary engine, the C2 had equal span single bay biplane wings with the lower mainplane set well below the fuselage attached by the rear undercarriage struts and a pair of struts at the leading edge. The undercarriage was of conventional tailskid configuration with the mainwheel axle attached to the fuselage by V-struts. Pilot and gunner were seated in individual cockpits with the pilot under the centre-section and the gunner aft of the wings, provided with a single fixed Vickers machine-gun fired by the pilot and a machine-gun on a ring in the rear cockpit. Development of the C2 did not continue after initial flight trials.
The Courtois-Suffit Lescop CSL C1 was a prototype French biplane fighter built in the final months of World War I. It was one of the first aircraft, if not the first, to be fitted with leading-edge flaps. It was not put into production.
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.
