The Sopwith Dragon was a British single-seat fighter biplane developed from the Sopwith Snipe.
In April 1918, the sixth Snipe prototype was fitted with a 320 hp (239 kW) ABC Dragonfly I radial engine. [1] [2] To compensate for the greater weight of the Dragonfly, the fuselage was lengthened by 22 in (56 cm). [3]
The prototype suffered persistent ignition system defects, but performance was encouraging when the Dragonfly engine operated properly. [3] [4] In June 1918, the Royal Air Force issued a contract for 30 Dragonfly-engined Snipes, which were subsequently named Dragons. [3] [4] In late November 1918, the RAF cancelled a production order for 300 Snipes and reordered the aircraft as Dragons. [1]
A second prototype was equipped with the larger 360 hp (268 kW) ABC Dragonfly IA engine. [1] This aircraft did not begin official trials at Martlesham Heath until February 1919. [4] It attained a top speed of 150 mph (240 km/h) at sea level and achieved a service ceiling of 25,000 ft. [1]
Sopwith built approximately 200 Dragon airframes, which were placed in storage pending delivery of their engines. [1] Difficulties with the Dragonfly ultimately proved impossible to resolve. Only a few aircraft were completed with Dragonfly engines, and none were issued to squadrons. [1] The Dragon was finally declared obsolete in April 1923. [5]

The Sopwith TF.2 Salamander was a British ground-attack aircraft of the First World War designed by the Sopwith Aviation Company which first flew in April 1918. It was a single-engined, single-seat biplane, based on the Sopwith Snipe fighter, with an armoured forward fuselage to protect the pilot and fuel system from ground fire during low level operations. It was ordered in large numbers for the Royal Air Force but the war ended before the type could enter squadron service, although two were in France in October 1918.
The Sopwith 7F.1 Snipe was a British single-seat biplane fighter of the Royal Air Force (RAF). It was designed and built by the Sopwith Aviation Company during the First World War, and came into squadron service a few weeks before the end of the conflict, in late 1918.
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 Boulton & Paul P.3 Bobolink was a World War I British single-engined single-seat fighter aircraft. It was built by Boulton & Paul Ltd.
The Nieuport Nighthawk was a British fighter aircraft developed by the Nieuport & General Aircraft company for the Royal Air Force towards the end of the First World War. Although ordered into production before the aircraft first flew, it did not enter large scale service with the RAF owing to unreliable engines. Re-engined aircraft did see service in Greece, serving from 1923 to 1938.
The ABC Dragonfly was a British radial engine developed towards the end of the First World War. It was expected to deliver excellent performance for the time and was ordered in very large numbers. It proved, however, to be extremely unreliable and was abandoned when its faults were unable to be corrected.
The Armstrong Whitworth Ara was an unsuccessful British single-seat biplane fighter aircraft of the First World War built by Armstrong Whitworth.
The Austin Greyhound was a British two-seat biplane fighter aircraft of World War I built by car manufacturer Austin. Owing to the end of the War and an unreliable engine, it was unsuccessful, only three being built.
The Nieuport B.N.1 was a prototype British single-engined fighter aircraft of the First World War. It was a single-engined biplane intended to replace the Sopwith Camel, but only one was built, being destroyed in a crash. The Sopwith Snipe was built instead to replace the Camel.
The Boulton & Paul P.7 Bourges was a prototype British twin-engined biplane day bomber built by Boulton & Paul to replace the Airco DH.10 Amiens. Despite demonstrating excellent performance and manoeuvrability, only three prototypes were built, post World War I cost cutting leading to the DH.10 not being replaced.
The Westland Wagtail was a prototype British fighter aircraft of the First World War. A single-engined tractor biplane, the Wagtail was a failure owing to the unreliability of its engine, only five being built.
The Sopwith 8F.1 Snail was a prototype British Fighter aircraft of the First World War. It was unsuccessful, being abandoned due to an unreliable engine.
The Westland Weasel was a prototype British two-seat fighter/reconnaissance aircraft of the First World War. Designed to replace the Bristol Fighter, the Weasel was a single engined tractor biplane. Four prototypes were built, but no production followed owing to the failure of its original engine, although the prototypes were used as engine test beds for the successful Armstrong Siddeley Jaguar and Bristol Jupiter engines.
The Sopwith Snapper was a prototype British fighter aircraft of the First World War. A single-engined biplane designed by the Sopwith Aviation Company to replace the Sopwith Snipe fighter, it first flew after the end of the war, but did not enter service owing to the failure of its engine, only three aircraft being built.
The BAT F.K.25 Basilisk was a prototype British fighter aircraft of the First World War. A single engined biplane intended to meet a requirement to replace the Sopwith Snipe, the Basilisk was unsuccessful, only three being built.
The Sopwith 2FR.2 Bulldog was a prototype British two-seat fighter of the First World War. A single-engined biplane, the Bulldog was a fighter/reconnaissance aircraft intended to replace the Bristol F.2 Fighter, but was unsuccessful, with no replacement for the Bristol Fighter being purchased.
The Sopwith Buffalo was a British armoured fighter/reconnaissance aircraft of the First World War. A single-engined biplane, two examples of the Buffalo were built by Sopwith to carry out reconnaissance missions low over the trenches while protected against machine-gun fire from the ground, but no production followed, with the end of the war removing the need for such an aircraft.
The Sopwith Snark was a British prototype fighter aircraft designed and built towards the end of the First World War to replace the RAF's Sopwith Snipes. A single engined triplane, the Snark did not fly until after the end of the war, only three being built.
The Sopwith 3F.2 Hippo was a prototype British two-seat fighter aircraft of the First World War. It was a single-engined biplane with considerable negative stagger. It was not successful, the Bristol F.2 Fighter being preferred by the Royal Flying Corps.
The Sopwith Cobham was a British twin-engined triplane bomber aircraft designed and built by the Sopwith Aviation Company during the First World War. The only twin-engined aircraft built by Sopwith, the Cobham did not fly until after the end of the war, and was unsuccessful due to the failure of its engines, only three prototypes being built.
