The de Havilland DH.103 Hornet, developed by de Havilland, was a fighter aircraft driven by two piston engines. It further exploited the wooden construction techniques that had been pioneered by the de Havilland Mosquito. Development of the Hornet had started during the Second World War as a private venture. The aircraft was to conduct long range fighter operations in the Pacific Theatre against the Empire of Japan but the war ended before the Hornet reached operational squadron status.
The Hornet entered service with RAF Fighter Command where it equipped several day fighter units and was commonly stationed in the British mainland. It saw combat in the Far East, being used as a strike fighter as part of the British military action taken during the Malayan Emergency. A naval carrier-capable version, the Sea Hornet, had been envisaged early on and was procured by the Fleet Air Arm of the Royal Navy.
Development
Origins
In the autumn of 1941, de Havilland found that it had the spare design capacity to work on a new project. At this point, the Mosquito had entered full-rate production and preliminary work on a jet-propelled fighter aircraft, which became the Vampire, was waiting for the production of prototype engines.[1] The company promptly recognised a need for a high-speed, unarmed, night bomber powered by a pair of large Napier Sabre piston engines and a design for such an aircraft was first proposed under the designation D.H. 101 in October 1941. A design team led by R. E. Bishop with C. T. Wilkins assisting, was assembled with the aim of developing the D.H. 101, which was initially pursued as a private venture.[2]
The Sabre engine was suffering from availability problems at that point and the DH. 101 was soon replaced by a lower-powered design, with the internal designation D.H. 102. This proposal was intended to be powered by a pair of Rolls-Royce Griffon or Rolls-Royce Merlin engines but either engine would have meant that the aircraft would be somewhat slower and less attractive than the Mosquito.[1]
By November 1942, de Havilland had elected to shelve the night bomber project and concentrate on producing a long-range fighter, the D.H. 103, that would make the maximum possible use of the Merlin engine.[1] The D.H. 103 resembled a small Mosquito, with a single seat; it was intended to take on other single-seat fighter aircraft, particularly those operated by Japan, while still being capable of conducting very long range missions to be of use in the Pacific Theatre. The long range requirement led to the fuselage being highly streamlined. An independently developed version of the Merlin engine which possessed a low frontal area was selected for use on the D.H. 103.[1]
By the end of 1942, a mock-up of the D.H. 103 had been completed at de Havilland's Hatfield facility and was soon afterwards demonstrated to officials of the Ministry of Aircraft Production.[1] Due to the war, the ministry did not immediately issue permission to construct the D.H. 103.[1] In June 1943, the project stopped being a private venture when the Ministry released Specification F.12/43, which had been written around the D.H. 103 proposal; soon after, the D.H. 103 project received the name Hornet.[1]
It was envisaged that the Hornet could be adapted for naval use and operated from the flight decks of aircraft carriers. Priority was given early on to ensuring that such adaptation could be readily done: measures for ease of control, especially when flown at low speeds, were incorporated and attention paid to providing the pilot with a high level of visibility.[3] The two propellers were driven in opposite directions to improve take-off and landing characteristics and high-drag flaps were integrated to provide for greater power during approaches.[3]
Prototypes and refinement
The Hornet prototype RR 915, 1944
By January 1944, the fuselage shell for the first prototype D.H. 103, RR915, was under construction on production jigs at Hatfield; RR915 was rolled out for engine runs on 20 July 1944.[1] On 28 July 1944, only thirteen months after the official sanction to proceed with development, RR915 conducted its maiden flight, piloted by Geoffrey de Havilland Jr., the company's chief test pilot.[1][4] Flight tests of RR915 led to it achieving a recorded speed of 485mph (780km/h) in level flight.[1] Within two months, over fifty flight hours were accumulated by RR915. The second prototype, RR919, was more representative of production aircraft, having provision for a pair of 200-gallon drop tanks and a pair of 1,000lbs bombs on hard points underneath the wings.[5]
Towards the end of 1944, the assembly line for the Hornet F.1, the initial production model, was being established at Hatfield and orders had already been received for the Royal Air Force (RAF).[6] On 28 February 1945, PX210, the first of 60 production F.1 aircraft was delivered to the Aeroplane and Armament Experimental Establishment (A&AEE) at RAF Boscombe Down. On 29 October 1945, a production Hornet F.1, PX237, was used for the type's first public appearance at an open day at RAE Farnborough.[6]
Additional prototypes were used for the development of improved variants of the Hornet. PX312, participated in the development of an improved fighter model to succeed the F.1, the Hornet F.3.[6]PX212, PX214, and PX219, were converted by the Heston Aircraft Company from Hornet F.1 standard aircraft to represent and test aspects of the initial naval version, later named Sea Hornet F.20.[3]PX212 and PX214 were only partially naval, being outfitted with arrestor hooks but lacking the wing-folding mechanisms of subsequent production aircraft; PX219 was the full naval version and later conducted carrier deck trials on board the aircraft carrierHMSOcean.[3]
PX230 and PX239, were completed for an all-weather night fighter, the Hornet NF.21.[7]PX239, originally built as a Hornet F.20, was outfitted with power-operated folding wings and a large dorsal fillet, which was later fitted to all production aircraft to comply with a new requirement to provide "feet off" directional stability with one engine stopped.[8] On 25 October 1948, the first deck trials commenced on board HMSIllustrious; these were so successful that testing rapidly proceeded to the night trials phase.[9] On 16 May 1947, PX230 was lost during service trials when the aircraft disintegrated in mid flight; the pilot bailed out following the breakup of the aircraft.[10]
Hornet F.3, PR.2 and FR.4
The wings of the Hornet F.3 were stressed to carry external weapons; two to four 60 lb (27 kg) RP-3 rockets could be carried under each wing; it was also possible to carry a combination of four rockets with one bomb of up to 1,000lb (454kg), or an additional drop tank on each wing, ranging in capacity up to 200Imp gal (909L).[6] Internally, the fuel tanks were enlarged from a total capacity of 360Imp gal (1,636L) to 432Imp gal (1,964L) and additional equipment was added. Larger horizontal tail surfaces were adopted, with larger elevator horn balances.[6] With the evolution of longer-range, jet-powered fighters such as the de Havilland Vampire, de Havilland Venom and Gloster Meteor, the Hornet became obsolete fairly quickly. The F.3 was the last Hornet derivative to see operational RAF service.[11]
The Hornet PR.2 was intended to operate as a long-range photo-reconnaissance aircraft.[6] The Hispano cannon were removed and cameras were mounted in the rear fuselage. Total internal fuel capacity was increased to 528gal (2,400L). PX216, PX220 and PX249, were converted from standard Hornet F.1 aircraft, later followed by five more. The requirement for these aircraft lapsed with the end of the Second World War in the Pacific; all were used in arrester barrier trials at Boscombe Down and scrapped before entering RAF service. Twelve Hornet FR.4s were modified from F.3s in much the same way, except that the cannon were retained and the internal fuel capacity slightly reduced from that of the fighter. These FR.4 derivatives saw service with the RAF in Malaya and Hong Kong in the early 1950s.
Sea Hornet F.20, NF.21 and PR.22
The Hornet was designed with the possibility of naval service on carriers firmly in mind. To this end good low-speed handling was required, along with good all-round visibility for the pilot. The basic Hornet design excelled at meeting these requirements. Shortly after the first Hornet prototype flew, Specification N.5/44 was issued to de Havilland, covering the modification of the Hornet for naval service. The Heston Aircraft Company was contracted to carry out the conversion work on three early production F.1s. The work entailed altering the wings to incorporate folding mechanisms so that each outer wing panel, from the aileron/flap line outboard could be folded upwards and inwards at an angle.[3] The hinges were part of the upper wing skin structure while the lower wing skins incorporated securing latches, and Lockheed hydraulic jacks were used to move the wing panels. Slotted flaps were introduced to improve low speed "flaps down" control.[3]

The lower rear fuselage was reinforced with two additional sprucelongerons designed to take the stresses imposed by the external "vee" framed arrestor hook, which was flush-mounted below the fuselage. The frame was made up of steel tubing with a forged-steel hook and was held against the fuselage by a "snap gear". Because the Hornet used the American "3-point" system of catapult-assisted takeoff, two forged steel catapult bridle hooks were fitted, one below each wing, close to the fuselage.[12] The de Havilland rubber-in-compression undercarriage legs could not absorb the rebound energies imposed by carrier landings. They were replaced by more conventional hydraulic oleos which embodied torque links.[13]
Merlin 133/134s (derated from 2,070hp (1,540kW) to 2,030hp (1,510kW)) were fitted to all Sea Hornets. Other specialised naval equipment (mainly different radio gear) was fitted and provision was made for three camera ports, one on each side of the rear fuselage and one pointing down. Sea Hornet F.20s also incorporated the modifications of the Hornet F.3, although the internal fuel capacity was 347Imp gal (1,557L), slightly reduced from that of the F.1. The modifications added some 550lb (249kg) to the weight of the aircraft. Maximum speed was decreased by 11mph (18km/h).[14]
The Hornet NF.21 was designed to fill a need for a naval night fighter. Special flame-dampening exhausts were installed, and a second basic cockpit was added to the rear fuselage, just above the wing trailing edges. ASH radar equipment was placed in the rear of this cockpit, with the radar operator/navigator seated facing aft.[7] To gain access, a small trapdoor was provided in the lower fuselage; a fixed, teardrop-shaped bubble canopy, which could be jettisoned in an emergency, provided a good field of view. At the front of the aircraft, the nose underwent a transformation with the small rotating ASH radar dish being housed under an elongated "thimble" radome.[7] The horizontal tail units were increased in span. The effect of these modifications on performance was minimal; about 4mph (6km/h).[7]
The Sea Hornet PR.22 was a dedicated photo reconnaissance aircraft version of the F.20. The cannon were removed and the apertures faired over. Three cameras were installed in the rear fuselage: two F.52s for night use and one K.19B for day. A total of 23 PR.22s were built, interspersed with F.20s being built at Hatfield.[15]
Civilian Hornet
The lone civilian Hornet, and the only one to be owned by a non-British operator, was a Sea Hornet F.20 TT193. It had originally been dispatched to Edmonton, Alberta, Canada to conduct winter trials; following these tests, TT193 was sold rather than be transported back to England. Registered CF-GUO, the aircraft was operated by Spartan Air Services and Kenting Aviation until 11 July 1952 when an engine failure caused a forced landing at Terrace, British Columbia.[16] After being reduced to components TT193 is to be restored to fly by Pioneer Aero Ltd at Ardmore, New Zealand.[17]
Flying the Sea Hornet

Just after VE Day the first semi-naval Sea Hornet PX 212 arrived at the RAE, Farnborough. Eric Brown initiated "work-up to deck-landing" trials. 37 years later, he was still impressed:
"...the next two months of handling and deck landing assessment trials were to be an absolute joy; from the outset the Sea Hornet was a winner!"
"The view from the cockpit, positioned right forward in the nose beneath a one-piece aft-sliding canopy was truly magnificent. The Sea Hornet was easy to taxi, with powerful brakes... the takeoff using 25lb (2,053mm Hg, 51" Hg) boost and flaps at one-third extension was remarkable! The 2,070hp (1,540kW) Merlin 130/131 engines fitted to the prototypes were to be derated to 18lb (1,691Hg, 37" Hg) boost and 2,030hp (1,510kW) as Merlin 133/134s in production Sea Hornets, but takeoff performance was to remain fantastic. Climb with 18 lb boost exceeded 4,000ft/min (1,200m/min)"...
"In level flight the Sea Hornet's stability about all axes was just satisfactory, characteristic, of course, of a good day interceptor fighter. Its stalling characteristics were innocuous, with a fair amount of elevator buffeting and aileron twitching preceding the actual stall"...
"For aerobatics the Sea Hornet was absolute bliss. The excess of power was such that manoeuvres in the vertical plane can only be described as rocket-like. Even with one propeller feathered the Hornet could loop with the best single-engine fighter, and its aerodynamic cleanliness was such that I delighted in its demonstration by diving with both engines at full bore and feathering both propellers before pulling up into a loop!"[18][N 1]
During this series of tests Captain Brown found that the ailerons were too heavy and ineffectual for deck landing and there were some problems with throttle movement, brakes and the rubber-in-compression undercarriage legs were still fitted. De Havilland were quick to modify the aircraft. Eric Brown:
"Landings aboard Ocean had been made without any crash barrier... Yet, in the case of the Sea Hornet, I had felt such absolute confidence that I was mentally relaxed... Indeed, there was something about the Sea Hornet that made me feel that I had total mastery of it; I revelled in its sleek form and the immense surge of power always to hand..."
"Circumstances had conspired against the Sea Hornet in obtaining the recognition that it justly deserved as a truly outstanding warplane...in my book the Sea Hornet ranks second to none for harmony of control, performance characteristics and, perhaps most important, in inspiring confidence in its pilot. For sheer exhilarating flying enjoyment, no aircraft has ever made a deeper impression on me than did this outstanding filly from the de Havilland stable."[19]
Design
A de Havilland Hornet F.1 flying at a steep bank angle
The de Havilland Hornet bore a family resemblance to the larger Mosquito, but it was an entirely fresh design albeit one that drew extensively upon experiences from, and the design of, the Mosquito.[1] It was powered by a pair of highly developed Rolls-Royce Merlin engines, producing 2,070hp (1,540kW) each, which drove de Havilland Propellers four-bladed propellers. According to aviation author P.J. Birtles, the efficiency and power of this configuration gave the Hornet "a higher performance than any other propeller driven aircraft".[1] The Hornet's principal armament was four short-barrelled 20mm (.79in) Hispano Vcannons, while other typical weapon loads included various rockets and bombs.[20]
Fuselage construction was identical to the earlier Mosquito: a balsa wood "pith" sandwiched between plywood sheets which were laid in diagonal panels. Aeroliteformaldehyde cement was the bonding agent.[21] The fuselage halves were built on large concrete or wood patterns and equipment was fitted in each half; they were then joined along the top and bottom centre lines using wooden reinforcing strips. The entire fuselage was then tightly wrapped in fine aviation fabric which was doped in place. The tailfin which had the trademark gracefully-curved de Havilland shape, was an integral part of the rear fuselage. On late F.1s and further models of production aircraft, a finfillet was added to the base of the unit.[22] The horizontal tail unit was an all-metal structure, again featuring the distinctive de Havilland shape,[14] which was later repeated on the Chipmunk and Beaver.
Construction was of mixed balsa/plywood similar to the Mosquito but the Hornet differed in incorporating stressed Alclad lower-wing skins bonded to the wooden upper wing structure using the new adhesiveRedux.[23] The two wing spars were redesigned to withstand a higher load factor of 10 versus 8.[14] Apart from the revised structure, the Hornet's wings were a synthesis of aerodynamic knowledge that had been gathered since the design of the Mosquito, being much thinner in cross-section, and with a laminar flow profile similar to the P-51 Mustang and Hawker Tempest. The control surfaces consisted of hydraulically-operated split flaps extending from the wing root to outboard of the engine nacelles; as on the Mosquito, the rear of the nacelle was part of the flap structure. Outboard, the Alclad-covered ailerons extended close to the clipped wing tips and gave excellent roll control.[12][22]
An RAF Hornet F.1 in level flight
The Hornet used "slimline" Merlin engines of types 130 and 131, which had engine ancillaries repositioned to minimise frontal area and drag. It was unusual for a British design in having propellers that rotated in opposite directions; the two engine crankshafts rotated in the same direction but the Merlin 131 added an idler gear to reverse its propeller's rotation (to clockwise, viewed from the front).[14] This cancelled the torque effect of two propellers turning in the same direction that had affected earlier designs (such as the Mosquito). [N 2] It also reduced adverse yaw caused by aileron trim corrections and generally provided more stable and predictable behaviour in flight. De Havilland tried propellers that rotated outward at the tops of their arcs (as in the P-38 Lightning),[25] but this configuration blanketed the fin and reduced rudder effectiveness at low speeds, compromising ground handling. On production Hornets the conventionally rotating Merlin 130 was on the port wing with the Merlin 131 on the starboard.[26][22]
Because of the revised induction arrangements of the Merlin 130 series, the supercharger and carburettor air intakes could be placed in the leading edges of the wings, outboard of the nacelles. (Other versions of the Merlin, which used "updraft" induction arrangements, required that the intakes be placed in a duct below the main engine cowling). The main radiators were also mounted in the inboard leading edges of the wings. Internal fuel, to a maximum capacity of 432Imp gal (1,964L) (F.3) was stored in four self-sealing wing tanks, which were reached through detachable panels forming part of the lower wing surfaces.[14] To assist airflow over the wing, the engine nacelles were mounted low, which meant that the undercarriage legs were reasonably short and the pilot's field of view was improved. The single-legged undercarriage units were simpler and cleaner than those of the Mosquito, using the same de Havilland-developed, rubber-in-compression energy absorption system. The main wheels were also smaller and lighter.[22]
To further aid the pilot's field of view, the unpressurised cockpit was mounted well forward in the fuselage and was housed under an aft-sliding perspexblister canopy. The three-panel windscreen was designed so that refraction through the panels meant that there were no obvious blind spots caused by the corner tie-rods; all three panels were bullet-proof laminated glass. An armour-plated bulkhead (hinged near the top to provide access to the back of the instrument panel and the rudder pedals), was part of the nose structure, with the pilot's back and head being protected by another armoured bulkhead built into the cockpit.[27] Below and behind the cockpit floor was a bay housing the aircraft's principal armament of four 20mm cannon, which had a maximum of 190 rounds per cannon which fired through short blast tubes. The Sea Hornet had a similar armament to its land-based counterparts.[28]
Operational history
Hornet
In mid-1946, the Hornet entered squadron service with 64 Squadron, based at RAF Horsham St Faith.[6] Next to convert to the Hornet was 19 Squadron at RAF Wittering, followed by 41 Squadron and 65 Squadron, both based at RAF Church Fenton. No. 65 Sqn participated in one of the first official overseas visits by an RAF unit when they visited Sweden in May 1948.[6] Pilot conversion to the Hornet was provided by No. 226 Operational Conversion Unit (O.C.U.) which was based at RAF Molesworth.[11][N 3]
During their relatively short operational service, Hornets participated in several record attempts and air races; for example, on 15 September 1949 Flight Lieutenant H. Peebles flew from RAF Bovingdon to Gibraltar (1,100+ mi or 1,800+ km) at an average speed of 357.565mph (574.445km/h), setting a new British point-to-point record.[6] Peebles' record stood for only three days, being broken when the same Hornet, flown by Group Captain A.P.C. Carver, returned to Bovingdon, averaging 435.871mph (701.466km/h).[6] On 31 August 1946, Geoffrey Pike attained third place in PX224 in the Lympne High Speed Handicap race, having flown a recorded average speed of 345.5mph (556.0km/h).[29] On 30 July 1949, PX286 participated in the National Air Races (GB) at Elmdon; when flown by Geoffrey Pike, it clocked the fastest lap at 369mph (594km/h) and attained second place overall.[29]
Operationally, the Hornet I (later re-designated as the F.1) lasted only a short time before being superseded by the improved F.3 version. The first Hornet F.3 was PX 366, which flew at the Farnborough Air Show in June 1946. New units to convert to this mark were 33 Squadron, 45 Squadron (based at RAF Tengah, Singapore where, in early 1952, the unit converted to the Hornet from the unreliable Bristol Brigand) and 80 Squadron.
In 1951, considerable numbers of Hornets were redeployed from Fighter Command to the squadrons of the Far East Air Force (FEAF).[29] Along with 45 Sqn, 33 and 80 Squadrons participated in combat operations during the Malayan Emergency. Upon arrival, the Hornets were promptly used to replace Bristol Beaufighters and Supermarine Spitfires that were being operated in support of ground security forces against Communistguerrillas fighting in the region.[29] Armed with rockets and/or 1,000lb (454kg) bombs, the Hornets, with their long range and good endurance, were able to spend up to two hours loitering over a given target area, which was particularly useful because target identification often proved to be challenging and time consuming.[29]
The Hornets were often sortied in conjunction with strikes from Avro Lincoln bombers.[29] Other activities included the aerial escorting of ground convoys. The Hornet proved to be very reliable: 45 Sqn Hornets, based in Singapore, achieved a total of 4,500 operational sorties over five years, more than any other squadron in the FEAF.[11][29]

On 1 June 1947, 801 Squadron was reformed to become the first squadron to operate the Sea Hornet, based at RNAS Ford.[7] After relocating to Arbroath, the squadron participated in numerous trials for the type prior to the Sea Hornet's first seaborne deployment, having embarked upon HMSImplacable in 1949. In 1951, a further transfer was made to HMSIndomitable: during their time on board the Sea Hornets contributed to a multinational maritime exercises as long-range fighter escort and strike aircraft; however, in June 1951, they were replaced by single-engined Hawker Sea Furies.[15][7]
Further Sea Hornet deliveries were attached to various Naval Squadrons, including three which were attached to 806 Squadron in 1948 which, along with a Vampire and two Sea Furies, were embarked on HMCS Magnificent for a tour of North America in 1948. During the North American tour, multiple Sea Hornets performed several spectacular flying displays at the International Air Exposition in New York City between 31 July and 8 August.[15][7] In mid-1948, one Sea Hornet, PX219, was adapted to carry a pair of Highball bouncing bombs in an installation that was developed, but not applied to the fleet. The equipment was removed during January 1949 and it is currently unknown if the Hornet ever dropped a Highball during flight.[33]
On 20 January 1949, 809 Squadron became the first squadron to be equipped with the Sea Hornet NF 21, having been reformed specifically to operate the type, based at RNAS Culdrose.[10] 809 Squadron was the only front-line unit to use this variant; following an initial workup period, the squadron briefly transferred to HMS Illustrious for deck landing practice. In May 1951, the NF.21s of 809 Squadron relocated to HMSVengeance to form a portion of the FAA's first all-weather air group.[10]
On 16 October 1951, a formation of four NF.21 aircraft flew non-stop from Gibraltar to Lee-on-the-Solent, Hampshire, England, in 3 hours 10 minutes at an average speed of just under 330mph; on 24 November 1951, a single Sea Hornet flew the same route in 2 hours 45 minutes at an average speed of 378mph.[10] During a brief deployment in 1952, it was quickly determined that the Sea Hornet was not suitable for use on board the Navy's light fleet carriers. 809 Squadron was briefly seconded to the RAF at Coltishall prior to being deployed to Hal Far, Malta; it was on Malta that the Squadron was disbanded in 1954 to be reequipped with the jet-powered de Havilland Sea Venom.[10]
The NF.21 later equipped the Fleet Requirements Units at Hal Far, Malta, and St Davids, West Wales.[10] One Sea Hornet F.20, TT 213, was acquired by the RAAF from the Ministry of Supply in the United Kingdom. The aircraft was used by the Aircraft Research and Development Unit (ARDU), at Laverton, Victoria, Australia from 1948 to 1950. It was mainly used for evaluation and tropical trials. Through 1956 and 1957, the majority of the retired Hornets were scrapped, having deteriorated badly due to the weather during storage.[34]

Royal Canadian Air Force operated briefly one former Royal Navy Sea Hornet F.20 (TT193) in 1948 for test purposes. It was operated by CEPE Canadian Experimental and Proving Establishment, at RCAF Namao, Edmonton, Alberta, in company with a Hawker Sea Fury. When surplused, it was purchased by Spartan Air Services and operated until one of the engines failed. It was scrapped sometime in the 1950s.[36]
The de Havilland DH.98 Mosquito is a British twin-engined, multirole combat aircraft, introduced during the Second World War. Unusual in that its airframe was constructed mostly of wood, it was nicknamed the "Wooden Wonder", or "Mossie". Lord Beaverbrook, Minister of Aircraft Production, nicknamed it "Freeman's Folly", alluding to Air Chief Marshal Sir Wilfrid Freeman, who defended Geoffrey de Havilland and his design concept against orders to scrap the project. In 1941, it was one of the fastest operational aircraft in the world.
The Gloster Meteor was the first British jet fighter and the Allies' only jet aircraft to engage in combat operations during the Second World War. The Meteor's development was heavily reliant on its ground-breaking turbojet engines, pioneered by Frank Whittle and his company, Power Jets Ltd. Development of the aircraft began in 1940, although work on the engines had been under way since 1936. The Meteor first flew in 1943 and commenced operations on 27 July 1944 with No. 616 Squadron RAF. The Meteor was not a sophisticated aircraft in its aerodynamics, but proved to be a successful combat fighter. Gloster's 1946 civil Meteor F.4 demonstrator G-AIDC was the first civilian-registered jet aircraft in the world. Several major variants of the Meteor incorporated technological advances during the 1940s and 1950s. Thousands of Meteors were built to fly with the RAF and other air forces and remained in use for several decades.
The Bristol Type 156 Beaufighter is a British multi-role aircraft developed during the Second World War by the Bristol Aeroplane Company. It was originally conceived as a heavy fighter variant of the Bristol Beaufort torpedo bomber. The Beaufighter proved to be an effective night fighter, which came into service with the Royal Air Force (RAF) during the Battle of Britain, its large size allowing it to carry heavy armament and early airborne interception radar without major performance penalties.
The de Havilland Vampire is a British jet fighter which was developed and manufactured by the de Havilland Aircraft Company. It was the second jet fighter to be operated by the RAF, after the Gloster Meteor, and the first to be powered by a single jet engine.
The Supermarine Scimitar is a single-seat naval strike aircraft that was designed and produced by the British aircraft manufacturer Supermarine. Operated exclusively by the Royal Navy's Fleet Air Arm, it was the final aircraft to be entirely designed and manufactured by Supermarine.
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 Blackburn Roc was a naval fighter aircraft designed and produced by the British aviation company Blackburn Aircraft. It took its name from the mythical bird of the tales of the Arabian Nights, the Roc. It was operated by the Fleet Air Arm (FAA) and was active during the Second World War.
The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and other operators as a primary trainer aircraft. In addition to the type's principal use for ab initio training, the Second World War had RAF Tiger Moths operating in other capacities, including maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers.
The de Havilland DH.110 Sea Vixen is a British twin-engine, twin boom-tailed, two-seat, carrier-based fleet air-defence fighter flown by the Royal Navy's Fleet Air Arm from the 1950s to the early 1970s. The Sea Vixen was designed by the de Havilland Aircraft Company during the late 1940s at its Hatfield aircraft factory in Hertfordshire, developed from the company's earlier first generation jet fighters. It was later called the Hawker Siddeley Sea Vixen after de Havilland was absorbed by the Hawker Siddeley Corporation in 1960.
The Supermarine Attacker is a British single-seat naval jet fighter designed and produced by aircraft manufacturer Supermarine for the Royal Navy's Fleet Air Arm (FAA). It was the first jet fighter to enter operational service with the FAA.
The de Havilland DH 112 Venom is a British post-war single-engined jet aircraft developed and manufactured by the de Havilland Aircraft Company. Much of its design was derived from the de Havilland Vampire, the firm's first jet-powered combat aircraft; it was initially referred to as the Vampire FB 8 prior to the adoption of the Venom name.
The de Havilland DH.87 Hornet Moth is a single-engined cabin biplane designed by the de Havilland Aircraft Company in 1934 as a potential replacement for its highly successful de Havilland Tiger Moth trainer. Although its side-by-side two-seat cabin made it closer in configuration to the modern aircraft that military trainee pilots would later fly, there was no interest from the RAF and the aircraft was put into production for private buyers.
The Supermarine Spiteful was a British Rolls-Royce Griffon–engined fighter aircraft designed by Supermarine to Air Ministry specification F.1/43 during the Second World War as a successor to the Spitfire. It had a new wing design to improve its critical Mach number, and allow safe operations at higher speeds. The new design also had a modern inwards-retracting undercarriage. Other changes included a larger fin to improve the somewhat marginal stability of Griffon Spitfires and changes to the mounting of the engine to tilt it down slightly for better visibility over the nose.
The de Havilland DH 108 "Swallow" was a British experimental aircraft designed by John Carver Meadows Frost in October 1945. The DH 108 featured a tailless, swept wing with a single vertical stabilizer, similar to the layout of the wartime German Messerschmitt Me 163 Komet. Initially designed to evaluate swept wing handling characteristics at low and high subsonic speeds for the proposed early tailless design of the Comet airliner, three examples of the DH 108 were built to Air Ministry specifications E.18/45. With the adoption of a conventional tail for the Comet, the aircraft were used instead to investigate swept wing handling up to supersonic speeds. All three prototypes were lost in fatal crashes.
The Vickers Type 432 was a British high-altitude fighter aircraft developed by the Vickers group during the Second World War. Intended to enable the Royal Air Force to engage the enemy's high-altitude bomber aircraft, it was to be armed with six cannons.
The Boulton Paul Balliol and Sea Balliol are monoplane advanced trainer aircraft designed and produced by the British aircraft manufacturer Boulton Paul Aircraft. On 17 May 1948, it became the world's first single-engined turboprop aircraft to fly. The Balliol was operated primarily by both the Royal Air Force (RAF) and the Royal Navy Fleet Air Arm (FAA).
The Short Sturgeon was a planned British carrier-borne reconnaissance bomber whose development began during Second World War with the S.6/43 requirement for a high-performance torpedo bomber, which was later refined into the S.11/43 requirement which was won by the Sturgeon. With the end of the war in the Pacific production of the aircraft carriers from which the Sturgeon was intended to operate was suspended and the original reconnaissance bomber specification was cancelled.
The Hawker Hurricane was a British single-seat fighter aircraft designed and predominantly built by Hawker Aircraft. Some versions were built in Canada by Canadian Car and Foundry.
The Westland Interceptor was a fighter developed by the British company Westland Aircraft to Air Ministry Specification F.20/27. When tested in 1929 and 1930, it showed unsatisfactory handling characteristics and was rejected by the RAF in favour of the Hawker Fury biplane fighter.
The de Havilland Mosquito was a British light bomber that served in many roles during and after the Second World War. Mosquito-equipped squadrons performed medium bomber, reconnaissance, tactical strike, anti-submarine warfare and shipping attack and night fighter duties, both defensive and offensive. Mosquitos were widely used by the RAF Pathfinder Force, which marked targets for night-time strategic bombing. Despite an initially high loss rate due to low-level daylight attack operations, the Mosquito ended the war with the lowest losses of any of the aircraft types in RAF Bomber Command service.
