Development
The aircraft was originally known as the DH.110; an aircraft designed for both the [Vous devez être inscrit et connecté pour voir ce lien] (RAF) and Fleet Air Arm (FAA) as an all-weather, missile-armed, high-speed jet fighter.
The [Vous devez être inscrit et connecté pour voir ce lien] had published a requirement for a fleet defence fighter to replace the [Vous devez être inscrit et connecté pour voir ce lien].
However, the RAF chose the [Vous devez être inscrit et connecté pour voir ce lien], a rival to the DH.110, after deciding the Javelin was a cheaper and simpler aircraft.
Despite this, de Havilland continued with the project, and by the late 1950s, the Royal Navy had placed an order and the aircraft entered service with the Fleet Air Arm.

Following a demonstration of the aircraft's ability to break the [Vous devez être inscrit et connecté pour voir ce lien], it disintegrated, killing 31 people, including the aircraft's two crew: test pilot and record breaker [Vous devez être inscrit et connecté pour voir ce lien] and Tony Richards.(See [Vous devez être inscrit et connecté pour voir ce lien].)
The failure was traced to faulty design of the end sections of the [Vous devez être inscrit et connecté pour voir ce lien], which resulted in the outer ends of the wings shearing off on execution of a high-rate turn.

The subsequent shift in the DH.110's [Vous devez être inscrit et connecté pour voir ce lien] caused the aircraft to lurch violently, creating forces of over 12 [Vous devez être inscrit et connecté pour voir ce lien], resulting in the cockpit and tail sections breaking away and the engines being torn from the airframe.
One engine landed safely in an unoccupied car park; however, the second engine ploughed into a crowded spectator
area at the end of the runway, causing the majority of casualties.
Others were injured by debris from the cockpit landing close to the main spectator enclosures alongside the runway.
This incident led to a major restructuring of the safety regulations for air shows in the UK, and since this accident no member of the public has died as a result of an airshow accident in the UK.

Owing to this incident, modifications were made to the other prototype.
In 1955, a semi-navalised variant was produced as a prototype for the production version, including change of leading edge profile and strengthening of wing (no folding wings), making its first flight that same year.

The following year, the aircraft made its first arrested deck landing on the fleet aircraft carrier [Vous devez être inscrit et connecté pour voir ce lien].
The first true Sea Vixen, the Sea Vixen FAW.20 (fighter all-weather, later redesignated FAW.1), first flew in 1957;
and in July 1959, the first of over 100 FAW.1s entered service with the Fleet Air Arm.

The original DH.110 design (as offered to the RAF) had the fitting of cannons in its prospectus; however, it was found during experiments conducted with [Vous devez être inscrit et connecté pour voir ce lien] that their firing caused failure of the mountings due to the force of the recoil.
The solution was to put a baulk (reinforcing piece) of timber in place to absorb the recoil force.
Thus the Vixen was also the last British fighter to use wood in its construction.
The cannons were soon removed and an all-missile armament was developed.

de Havilland dH-110 Sea Vixen D3, formerly of the Royal Navy as XP924, now on the UK Civil Register as G-CVIX, is maintained by De Havilland Aviation Ltd. at Bournemouth Airport, Dorset, England.
The aircraft was in Red Bull advertising markings but has been repainted in its Royal Navy Fleet Air Arm markings.
XP924 entered service with the Royal Navy in 1964 as an FAW.2 model.
It ended its flying in 1991 as a trainer for teaching pilots to fly aircraft by remote control from the ground (for use as missile targets).

The Sea Vixen FAW.2 was the successor to the FAW.1 and included many improvements.
As well as Firestreak missiles, it could carry the [Vous devez être inscrit et connecté pour voir ce lien] AAM, four [Vous devez être inscrit et connecté pour voir ce lien] rocket pods and the air-to-ground [Vous devez être inscrit et connecté pour voir ce lien].

An enlarged tail boom allowed for additional fuel tanks in the "pinion" extensions above and before the wing leading edge, and there was an improved escape system along with additional room for more electronic counter-measures equipment.
