The Supermarine Type 324 and Type 325 were British two-engined fighter designs proposed as the replacement for the Supermarine Spitfire and Hawker Hurricane. Neither of them nor a revised design - the Type 327 - to carry cannon was accepted for development and production. ==Development== As an aircraft to succeed the Hurricane and Spitfire then entering service, Air Ministry specification F.18/37 required a 400+ mph (at 15,000 ft) fighter with twelve .303 inch machine gun armament. Hawker Aircraft submitted a single seat, single engine design with two possible engines, the Hawker Tornado powered by the Rolls-Royce Vulture and the Hawker Typhoon, with Napier Sabre engine. Gloster submitted two similar twin-boom designs with 12 Browning machine guns in the nose and a pusher Sabre engine as well as an adaptation of their proposal to F.9/37 with nose-mounted armament. Bristol's design was one airframe offered with three alternative engines. In 1938 Supermarine submitted brochures describing the Type 324 (under the company specification No.458) along with the Type 325. Both were compact twin-engine designs - one tractor and one pusher - with either Rolls-Royce Merlin or Bristol Taurus engines. Hawker's designs - which Sydney Camm had been working on since April 1937 - were accepted and prototypes of each ordered. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Supermarine Type 324」の詳細全文を読む スポンサード リンク
