The Hawker P.1103 was a design by Hawker Aircraft to meet the British Operational Requirement F.155; it did not progress further than the drawing board.
Operational Requirement F.155 was an Operational Requirement issued by the British Ministry of Supply in 1955 for an interceptor aircraft to defend the United Kingdom from high flying supersonic bombers.
F.155 specified exacting demands:
The Ministry of Supply made clear in the requirement that the plane and missiles should be treated as a "weapon system" i.e., a cohesive whole. The armament specifications were covered by a separate Operational Requirement, OR.1131, which listed two missile systems: the infra-red guided de Havilland "Blue Vesta" and the radar-guided Vickers "Red Hebe".
The submission by Hawker Siddeley a design by the legendary designer Sir Sydney Camm was effectively a supersonic development of his successful Hawker Hunter design, using a single engine - a 25,000 lb development of the de Havilland Gyron breathing through an under-chin air intake. [1] Two detachable rocket boosters, to give a 3.7 minute boost, were carried in mid-wing nacelles.
Although a nuclear threat from high-flying Soviet supersonic nuclear-armed bombers was identified in 1955, F.155 calling for supersonic interceptors (in service by 1962) was superseded by the 1957 Defence White Paper. The paper was a major review of military spending and one of its elements was the cancellation of nearly all manned fighter projects as a radical change had occurred in strategic threats with the expectation that intercontinental ballistic missiles and low-level strike would replace high flying bombers.

The British Aircraft Corporation TSR-2 is a cancelled Cold War strike and reconnaissance aircraft developed by the British Aircraft Corporation (BAC), for the Royal Air Force (RAF) in the late 1950s and early 1960s. The TSR-2 was designed around both conventional and nuclear weapons delivery: it was to penetrate well-defended frontline areas at low altitudes and very high speeds, and then attack high-value targets in rear areas. Another intended combat role was to provide high-altitude, high-speed stand-off, side-looking radar and photographic imagery and signals intelligence, aerial reconnaissance. Only one airframe flew and test flights and weight-rise during design indicated that the aircraft would be unable to meet its original stringent design specifications. The design specifications were reduced as the result of flight testing.
The Gloster Javelin is a twin-engined all-weather interceptor aircraft that served with Britain's Royal Air Force from the mid-1950s until the late 1960s. It was a T-tailed delta-wing aircraft designed for night and all-weather operations and was the last aircraft design to bear the Gloster name. Introduced in 1956 after a lengthy development period, the aircraft received several upgrades during production to its engines, radar and weapons, including support for the De Havilland Firestreak air-to-air missile.
The Bristol 188 is a British supersonic research aircraft built by the Bristol Aeroplane Company in the 1950s. Its length, slender cross-section and intended purpose led to its being nicknamed the "Flaming Pencil".
The Saunders-Roe SR.53 was a British prototype interceptor aircraft of mixed jet and rocket propulsion developed for the Royal Air Force (RAF) by Saunders-Roe in the early 1950s. As envisaged, the SR.53 would have been used as an interceptor aircraft, using its rocket propulsion to rapidly climb and approach incoming hostile bombers at high speeds; following its attack run, the aircraft would then return to its base using jet propulsion.
The Saunders-Roe SR.177 was a 1950s project to develop a combined jet- and rocket-powered interceptor aircraft for the Royal Air Force (RAF) and Royal Navy. It was an enlarged derivative of the Saunders-Roe SR.53, which was itself an experimental combined jet-and-rocket interceptor aircraft.
The North American XF-108 Rapier was a proposed long-range, high-speed interceptor aircraft designed by North American Aviation intended to defend the United States from supersonic Soviet strategic bombers. The aircraft would have cruised at speeds around Mach 3 with an unrefueled combat radius over 1,000 nautical miles, and was equipped with radar and missiles offering engagement ranges up to 100 miles (160 km) against bomber-sized targets.
The de Havilland Firestreak is a British first-generation, passive infrared homing air-to-air missile. It was developed by de Havilland Propellers in the early 1950s, entering service in 1957. It was the first such weapon to enter active service with the Royal Air Force (RAF) and Fleet Air Arm, equipping the English Electric Lightning, de Havilland Sea Vixen and Gloster Javelin. It was a rear-aspect, fire and forget pursuit weapon, with a field of attack of 20 degrees either side of the target.
The Hawker Siddeley Red Top was the third indigenous British air-to-air missile to enter service, following the de Havilland Firestreak and limited-service Fireflash. It was used to replace the Firestreak on the de Havilland Sea Vixen and later models of the English Electric Lightning.
The Grumman G-118 was a design for an all-weather missile-armed interceptor aircraft for use on US Navy aircraft carriers. Originally conceived as an uprated F11F Tiger, it soon evolved into a larger and more powerful project. Although two prototypes were ordered in 1955, development was cancelled the same year in favor of the F4H Phantom II before any examples were built. Grumman's next carrier fighter would be the F-14 Tomcat, ordered in 1968.
The de Havilland PS.23 or PS.52 Gyron, originally the Halford H-4, was Frank Halford's last turbojet design while working for de Havilland. Intended to outpower any design then under construction, the Gyron was the most powerful engine of its era, producing 20,000 lbf (89 kN) "dry", and 27,000 lbf (120 kN) with reheat.
The Hawker Siddeley P.1154 was a planned supersonic vertical/short take-off and landing (V/STOL) fighter aircraft designed by Hawker Siddeley Aviation (HSA).
The Rockwell XFV-12 was a prototype supersonic United States Navy fighter which was built in 1977. The XFV-12 design attempted to combine the Mach 2 speed and AIM-7 Sparrow armament of the McDonnell Douglas F-4 Phantom II in a VTOL fighter for the small Sea Control Ship which was under study at the time. On paper, it looked superior to the subsonic Hawker Siddeley Harrier attack fighter. However it was unable to demonstrate an untethered vertical takeoff and its inability to meet performance requirements terminated the program.
Red Dean, a rainbow code name, was a large air-to-air missile developed for the Royal Air Force during the 1950s. Originally planned to use an active radar seeker to offer all-aspect performance and true fire-and-forget engagements, the valve-based electronics demanded a missile of prodigious size.
Operational Requirement F.155 was a specification issued by the British Ministry of Supply on 15 January 1955 for an interceptor aircraft to defend the United Kingdom from Soviet high-flying nuclear-armed supersonic bombers.
The Vickers Type 559 was a supersonic interceptor aircraft design by the British aircraft company Vickers-Armstrongs and was their submission for Operational Requirement F.155 in 1955.
The Leduc 022 was the prototype of a mixed-power French interceptor built in the mid-1950s. Designer René Leduc had been developing ramjet-powered aircraft since before World War II and had flown a series of experimental aircraft, the Leduc 0.10 and Leduc 0.21, throughout the Fifties before he was awarded a contract for two examples of a short-range supersonic interceptor armed with two air-to-air missiles (AAMs).
The Hawker P.1121 was a British supersonic fighter aircraft designed, but never fully completed, by Hawker Siddeley during the mid-1950s. It was designed by a team headed by Sir Sydney Camm.
The Avro 720 was an in-development British single-seat interceptor of the 1950s. It was designed and being developed by Avro in competition with the Saunders-Roe-built SR.53. While at least one prototype was partially-constructed, the order for the Avro 720, and quickly thereafter the project entirely, was terminated prior to any aircraft having been completed.
The British Aerospace (BAe) P.1216 was a planned Advanced Short Take Off/Vertical Landing (ASTOVL) supersonic aircraft from the 1980s. It was designed by the former Hawker design team at Kingston upon Thames, Surrey, England that created the Harrier family of aircraft.
Red Hebe was a large active radar homing air-to-air missile developed by Vickers for the Royal Air Force's Operational Requirement F.155 interceptor aircraft. It was a development of the earlier Red Dean, which was not suitable for launch by the new supersonic aircraft. Before progressing much beyond advanced design studies, F.155 was cancelled in the aftermath of the 1957 Defence White Paper which moved Britain's attention from strategic bombers to ballistic missiles. With no other suitable platform, Red Hebe was cancelled as well.
