The Vickers Type 432 was a British design for a cannon-armed fighter capable of engaging high altitude bombers during the Second World War for use by the Royal Air Force, developed by the British Vickers group.

Design and development

The design was first submitted to Air Ministry specification F.22/39 as the Vickers 414 to meet Operational Requirement (OR) 76. This was subsequently revised with aircraft redesigns to become specifications F.16/40 and then F.7/41 for OR. 108

In appearance it resembled a larger version of the de Havilland Mosquito. The pilot had a pressurized cockpit in the nose, with a bubble dome, similar to an enlarged astrodome. The pressurised cockpit took up the nose section so the cannon would have been fitted in a fairing below the fuselage, to the rear of the aircraft.

Operational history

The first prototype Type 432 was flown on 24 December 1942; initial trials revealing serious handling difficulties on the ground, the aircraft snaking while taxiing, necessitating aft movement of the mainwheels to correct the bad tracking. In flight tests, the Type 432 was unable to be landed in a standard "three-point" stance resulting in the replacement of the Irving-type ailerons with new Westland types along with an alteration of tail settings. The estimated maximum speed of 700 km/h at 8,535 m (435 mph at 28,000 ft) was never attained as the Merlin 61 engines did not run satisfactorily above 7,010 m (23,000 ft).

When the competing Westland Welkin was ordered into production, the second prototype of the Vickers fighter, the Type 446, was cancelled before completion on 1 May 1943. The first prototype was retained by Vickers for test purposes until the end of 1944, when the aircraft was scrapped after completing only 30 flights.
