The Hawker Typhoon is a British single-seat fighter-bomber, produced by Hawker Aircraft. It was intended to be a medium-high altitude interceptor, as a replacement for the Hawker Hurricane, but several design problems were encountered and it never completely satisfied this requirement.
The Hawker Tempest is a British fighter aircraft that was primarily used by the Royal Air Force (RAF) in the Second World War. The Tempest, originally known as the Typhoon II, was an improved derivative of the Hawker Typhoon, intended to address the Typhoon's unexpected deterioration in performance at high altitude by replacing its wing with a thinner laminar flow design. Since it had diverged considerably from the Typhoon, it was renamed Tempest. The Tempest emerged as one of the most powerful fighters of World War II and at low altitude was the fastest single-engine propeller-driven aircraft of the war.
The Avro 679 Manchester was a British twin-engine heavy bomber developed and manufactured by the Avro aircraft company in the United Kingdom. While not being built in great numbers, it was the forerunner of the more famed and more successful four-engined Avro Lancaster, which was one of the most capable strategic bombers of the Second World War.
The Vickers Warwick was a British twin-engined bomber aircraft developed and operated during the Second World War that was primarily used in other roles. In line with the naming convention followed by other RAF heavy bombers of the era, it was named after a British city or town, in this case Warwick. The Warwick was the largest British twin-engined aircraft to see use during the Second World War.
The Rolls-Royce Vulture was a British aero engine developed shortly before World War II that was designed and built by Rolls-Royce Limited. The Vulture used the unusual "X-24" configuration, whereby four cylinder blocks derived from the Rolls-Royce Peregrine were joined by a common crankshaft supported by a single crankcase. The engine was originally designed to produce around 1,750 horsepower (1,300 kW) but problems with the Vulture design meant that the engines were derated to around 1,450 to 1,550 hp in service by limiting the maximum rpm.
The Hawker Nimrod is a British carrier-based single-engine, single-seat biplane fighter aircraft built in the early 1930s by Hawker Aircraft.
The Republic XP-69 was an American fighter aircraft proposed by Republic Aviation in 1941 in response to a requirement by the United States Army Air Corps for a high-speed fighter. Manufacturers were encouraged to consider unorthodox designs; although the design was ordered as a prototype it was canceled because of delays with the engine that was to power it.
The Hawker Hotspur was a fighter aircraft developed between the wars for the Royal Air Force. It was designed in response to Air Ministry Specification F.9/35, which required a powered turret as the main armament to replace the Hawker Demon. It was developed from the Hawker Henley, a competitor for the light bomber role but put into production as a target tug, and fitted with a Boulton-Paul powered four gun turret.
The Hawker Hornbill was the last Hawker military aircraft designed under the direction of George Carter. The design was started in 1925 and the first flight took place in July 1925. The Hornbill did not achieve service in the Royal Air Force due to problems in its power plant and radiator. Only one aircraft was built.
The Fairey Spearfish was a British carrier-based, single-engined, torpedo bomber/dive bomber that was ordered from Fairey Aviation for the Fleet Air Arm during World War II. Designed during the war, the prototype did not fly until July 1945. Much larger than earlier naval bombers, it was designed for use aboard the large Malta-class aircraft carriers that were cancelled after the war and was itself cancelled thereafter. Seven prototypes were ordered, but only five were built, of which four actually flew. They were mostly used for experimental work until the last aircraft was scrapped in 1952.
The Blackburn Firebrand was a British single-engine strike fighter for the Fleet Air Arm of the Royal Navy designed during World War II by Blackburn Aircraft. Originally intended to serve as a pure fighter, its unimpressive performance and the priority allocation by the Ministry of Aircraft Production of Napier Sabre engines to the Hawker Typhoon caused it to be redesigned with an alternative engine as a strike fighter to take advantage of its load-carrying capability. Development was slow and the first production aircraft was not delivered until after the end of the war. Only a few hundred were built before it was withdrawn from front-line service in 1953.
The Avro 549 Aldershot was a British single-engined heavy bomber aircraft built by Avro.
The Boulton Paul P.92 was a British design by Boulton Paul for a two-seat, turret-armed, twin-engine heavy fighter and ground attack aircraft to meet Air Ministry Specification F.11/37. Only a half scale prototype – the P.92/2 – was built and tested as check on aerodynamics before the project was cancelled in 1940.
The Blackburn B.48 Firecrest, given the SBAC designation YA.1, was a single-engine naval strike fighter built by Blackburn Aircraft for service with the British Fleet Air Arm during the Second World War. It was a development of the troubled Firebrand, designed to Air Ministry Specification S.28/43, for an improved aircraft more suited to carrier operations. Three prototypes were ordered with the company designation of B-48 and the informal name of "Firecrest", but only two of them actually flew. The development of the aircraft was prolonged by significant design changes and slow deliveries of components, but the determination by the Ministry of Supply in 1946 that the airframe did not meet the requirements for a strike fighter doomed the aircraft. Construction of two of the prototypes was continued to gain flight-test data and the third was allocated to strength testing. The two flying aircraft were sold back to Blackburn in 1950 for disposal and the other aircraft survived until 1952.
The Avro 604 Antelope was a British light bomber which was designed and built in the late 1920s to meet a requirement for a light bomber to equip the Royal Air Force, competing against the Hawker Hart and the Fairey Fox II. It was unsuccessful, the Hart being preferred.
The Blackburn T.4 Cubaroo was a British prototype biplane torpedo bomber of the 1920s. Built by Blackburn Aircraft and intended to carry a large 21 in (533 mm) torpedo, the Cubaroo was claimed to be the largest single-engined aircraft in the world at the time of its first flight.
The Blackburn 2F.1 Nautilus was a British single-engine two-seat biplane spotter/fighter built in 1929. Only one was completed.
The Avro 684 was a proposed British high altitude heavy bomber of the Second World War, based on Avro's successful Lancaster.
The de Havilland DH.27 Derby was a large single-engined biplane designed to a heavy day bomber Air Ministry specification. It did not reach production.
The Supermarine Type 324 and Type 325 were British two-engined fighter designs proposed as the replacement for the Supermarine Spitfire and Hawker Hurricane. Neither of them nor a revised design - the Type 327 - to carry cannon was accepted for development and production.
