Origins

Towards the end of the

engine, being fitted in a mid-fuselage position, along with lateral air intakes and a tailpipe which emerged beneath the tailplane. The prospective modifications also included "stretching" the fuselage and moving the cockpit to the extreme front of the fuselage in a re-contoured nose; this design received the internal designation ''P.1035''. Use of the Rolls-Royce Derwent engine had been studied but quickly discarded as lacking power for an aircraft of this size. In November 1944 the ''P.1035'' design was submitted for evaluation by the

. In December 1944 Hawker refined the proposed design substantially. The jet exhaust was moved from beneath the tail and re-designed as two short split-lateral bifurcated exhausts (which gained the name "trouser legs"), embedded in the

. The shorter unusual bifurcated jet pipe reduced pressure losses in the jet pipe and had the additional advantage of freeing up space in the rear fuselage for fuel tanks, which gave the aircraft a longer range than many other early jets.Badrocke 2002. p. 60. The absence of wing fuel tanks also meant a thinner wing could be adopted without the penalty of reduced range; to ease manufacture, the elliptical wingform of the Fury was discarded in favour of a straight

design. The fuselage fuel tanks, being fore and aft of the engine, also provided for a stable centre of gravity during flight. The tail plane was raised to clear the jet exhausts.

(RAF) and to the Navy. The P.1040 was intended to be an interceptor, even though a top speed of only 600 mph was forecast. Shortly following the end of the war, the RAF decided to cancel several large orders for Hawker's piston-powered aircraft and to announce that the service would be taking no further interest in the ''P.1040'' proposals. Hawker elected to refine the ''P.1040'' design as a private venture, albeit being prepared with a view for service with British military customers in mind. In October 1945, Sydney Camm, Hawker's chief designer, being satisfied with the results generated from engineering mock-ups and

and de Havilland Vampire, in January 1946, a naval version of the P.1040 was offered by Hawker to the Admiralty as a fleet support fighter, as the ''P.1046''.Mason 1991, p. 316. The Admiralty was not enthusiastic, in part due to the development of the jet-powered Supermarine Attacker aircraft. The service was however intrigued by the long-range of the ''P.1040'' and the promise of increased power from the Nene engine. In May 1946, the Naval Staff authorised the manufacture of three prototypes and a further test specimen, one of these being the original prototype internally ordered by Hawker, in accordance with Naval Specification N.7/46. Hawker quickly found their development focus for the type being divided between the naval ''P.1046'' and the general-purpose ''P.1040'', which was still hoped to be viable as an RAF fighter. The ''P.1040'' would lead to the eventual development of the land-based

Prototypes

On 2 September 1947, the P.1040 prototype, ''VP401'', sometimes referred to as the ''Hawker N.7/46'' after the related naval specification, conducted its
maiden flight The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is alw ...

to continue trials.Mason 1966, pp. 4-5. A month after the first flight, the existence of the P.1040 was revealed to the general public.Mason 1966, p. 5. Early flight trials encountered aerodynamically-related teething problems, such as airframe vibrations and tail buffeting, which led to a redesign of the rear jet pipe fairings and the addition of a bullet-shaped anti-shock body on the tail. Other minor issues were addressed, including high stick forces and windscreen distortion; ''VP401'' needed long take-off runs which were attributed to the "low-thrust" Nene 1. The Nene 2/Mk.101 for production aircraft would have a higher take-off thrust. On 31 August 1948, a naval prototype, ''VP413'', equipped with folding wings, catapult spools and armament, conducted its first flight. ''VP413'' was quickly subjected to a series of deck assessment trials using a mock-up deck at Boscombe Down. In April 1949, ''VP413'' was transferred to the aircraft carrier to conduct general deck and handling trials at sea. These trials revealed the need for the wing span to be increased by 30 inches, the low-speed handling of the prototype having been found to be lacking. In November 1949, ''VP413'' returned to ''Illustrious'', performing around 25 deck landings without issue. On 17 October 1949, the third prototype, ''VP422'', made its maiden flight. Being representative of the production aircraft, ''VP422'' incorporated a number of modifications as a result of experience gained from trials with the second prototype, these alterations included the fitting of a longer arrester hook when a number of " bolters" were experienced during the early dummy deck trials. After the longer hook was incorporated, this modification was carried though the remaining production runs. Other changes included the addition of fixtures for rocket-assisted take-off gear (RATOG) and

s plumbed for external drop tanks. On 22 November 1949, Hawker received an initial production contract for 151 aircraft named Sea Hawk. Throughout 1950, both ''VP413'' and ''VP422'' were used for preliminary service trials. ''VP422'', the third prototype, later joined a specially-prepared Vampire Mk 21 in testing the feasibility of operating without an undercarriage, using a flexible deck. Flying from

. Although the trials were successful, the project was abandoned when the introduction of more powerful engines obviated the need radically to adapt the design to the concept of combat aircraft without undercarriages. ''VP401'', the first prototype, had continued to serve in the flight test programme and was involved in two significant events prior to its retirement. On 1 August 1949, the Royal Navy entered ''VP401'' in the National Air Races, in which it won the

Production

Immediately following the receipt of the first order in November 1949, Hawker set about establishing a manufacturing line for the Sea Hawk at their Kingston facility. Shortly after the outbreak of the

The first Coventry-built Sea Hawk F1 made its first flight prior to the end of 1953; a total of 60 would be produced. While some of the initial batch of Sea Hawks would see operational service, many of the F1s would be used for various service trials. Amongst these, ''WF143'' would later be rebuilt as the prototype for the Sea Hawk F2, featuring power-assisted

. A total of 40 F2 aircraft would be produced. Another Sea Hawk F1, ''WF157'', was developed into a prototype for the FB 3 standard, the initial fighter bomber variant of the type and later most common of the Sea Hawk variants. To suit this role, much of the development work went into its range of external stores, although the clearance of these for service was disrupted by a lack of Royal Navy personnel. On 13 March 1954, the first production Sea Hawk FB 3, ''WF280'', made its first flight. A more refined Sea Hawk FGA 4 variant followed, partially to remedy stores handling problems that had been experienced with the FB 3 variant; the first FB 4 aircraft, ''WV792'' conducted its first flight on 26 August 1954.Mason 1966, p. 7. In 1950, it was acknowledged that the Nene 101 engine was transitional powerplant; upon availability of the 4 per cent more powerful Nene 103, the Admiralty quickly ordered many of its Sea Hawk FB 3 and FGA 4 to be re-engined. Another two Sea Hawk variants were developed; the first of these, the FB 5, was more or less identical to the FB 3 apart from the newer, more powerful Nene 103 engine, which greatly improving the aircraft's low-speed handling and take-off performance. The final Sea Hawk standard, FGA 6, was a fighter ground-attack variant, the same as its ''FB 5'' predecessor, though they were new-build aircraft rather than re-engined ones. A total of just under 90 FGA 6s were completed.

More minor developments of the Nene engine were developed and were adopted on the aircraft, providing for some increase in power. The F 1 had a maximum speed of 599 mph (964 km/h) at sea level and a range of 800 mi (1,287 km) on internal fuel. A more refined fighter variant was the F 2, which introduced power-boosted aileron controls as well as other modifications, including to its structure. The next variant of the Sea Hawk was developed into a fighter-bomber, the FB 3, and differed only slightly from its predecessors; its structure being strengthened to allow it to carry a wider array of equipment and weaponry on its four

Operational history

The first production Sea Hawk was the ''F 1'', which first flew in 1951, entered service two years later with 806 Squadron, first based at Brawdy, then transferred to . All Sea Hawks were in service by the mid-1950s and eventually over 500 were built.Green 1982, p. 49. During service evaluations of the Sea Hawk, Australian and Canadian naval pilots flew the aircraft leading to official suggestions that the aircraft would be chosen by the two countries.Mason 1966, pp. 8–9. Both nations were also interested in new American-built naval aircraft; only a handful of Sea Hawks were transferred to either nation, some operating from the flight deck of the Australian ''Majestic''-class aircraft carrier , though these did not enter full squadron service.Mason 1966, p. 9.
