FLIGHT, 31 August 1956 GLOSTER AIRCRAFT CO., LTD. Gloucester, Glos. Telephone: Gloucester 66294 Javelin. The physical characteristics of the Javelin delta-wing two-seat all-weather fighter (two Armstrong Siddeley Sapphires) have been familiar for some five years past. Little was known of its operational qualities, however, until the first visit to a Javelin squadron was permitted in July this year. The assurance was forthcoming on that occasion that the Javelin is light and pleasant on the controls. The ailerons are fully powered and the elevator and rudder are hydraulically assisted. Tailplane incidence is variable by an electric motor and is screw-jack controlled from a switch on the control column. Any degree of air-brake extension can be selected and the large comb-like braking surfaces, which extend above and below each wing, were reported to be extremely effective. Provision is made for pressure-refuelling through a single connection at the port wing root, and capacity is such that the length of a sortie was officially stated to be "considerably greater" than that of previous night fighters. Provision is made for two large auxiliary ventral tanks and these will probably double the endurance. The wide-track Dowty undercarriage and Maxaret equipment give excellent braking and control on the ground both during landing and taxying. Single-engined flight would appear to present no problems and, because the engines are toed in, and lie very close to the centre-line, the large rudder tab should be sufficient to trim out full power on one engine right down to minimum flying speed. Variants in service are the FAW.l and FAW.4, which are superficially similar. The latest mark is the FAW.7, which appears to have Armstrong Siddeley Sapphires of increased (possibly five-figure) thrust. A dual-control trainer version is being developed by Air Service Training, Ltd., but a project for a supersonic thin-winged Olympus-powered fighter has now been shelved. Current marks are armed with four 30 mm Aden guns and, according to an official statement, the Javelin is intended to carry guided missiles.
