The last design of the Gloster Aircraft Co. Ltd to enter service was the Javelin all weather fighter, with its unique tailed delta configuration.
The first prototype Gloster GA.5 WD804 was taken by road from Hucclecote to Moreton Valence for its first flight, which took place on 26th November 1951.
The first production Javelin FAW.1 XA544 was flown on 22nd July 1954. Significant developmental changes were made between the initial GA.5, and the production aircraft, including changes to the canopy, nose profile, wing planform and flight controls.
Modifications, in particular to the wing, continued during the aircraft’s production run.
Air Service Training at Hamble was responsible for the design of the forward fuselage modifications for the Gloster Javelin T. Mk 3 operational trainer.
The T. Mk 3 prototype WT841 was assembled at Hamble, before being disassembled and moved by road to Gloucester for its first flight. This took place on 20th August 1956. A further 22 production Javelin T. Mk 3 were subsequently built by Gloster.
Including the GA.5 prototypes, Gloster built 302 Javelin aircraft, and Sir W.G. Armstrong Whitworth Aircraft Ltd built a further 133 at Coventry, giving a total of 435 aircraft.
The most important marks were the FAW.4 (50 aircraft, first flown 19 September 1955), FAW.5 (64) and the FAW.7 (142). Seventy-six of the FAW.7 aircraft were subsequently modified to become Javelin FAW. 9.
