Fundamentally a redesigned and improved Type 151 Jockey and, indeed, initially known as the Jockey II, the Type 279, for which Vickers adopted the name Venom, was intended to meet the requirements of Specification F.5/34. Powered by a 625hp Bristol Aquila AE.3S nine-cylinder sleeve-valve radial engine enclosed by a long-chord NACA cowling, the Venom was a highly sophisticated aircraft, with a metal monocoque fuselage, its stressed skin being affixed by countersunk rivets. It was unique at the time it entered flight test, on 17 June 1936, in having 90°-deflection flaps. The Venom retained the sideways-hinging engine feature of the Type 151, and a battery of eight 7.7mm machine guns was mounted in the wings from the start of test flying. The Venom proved exceptionally manoeuvrable, with outstanding roll rate and turning radius, but it lacked the power to compete seriously with its Rolls-Royce liquid-cooled Vee-type-engined contemporaries, and, as no sufficiently compact British air-cooled radial of adequate power was available for installation, it was scrapped in 1939.
