The Gloster F.9/37 was a British twin-engined design for a cannon-armed fighter to serve with the Royal Air Force planned before the Second World War. Although it was initially favoured, the Gloster F.9/37 was not able to compete with other, more advanced designs.

Design and development

It was designed under the direction of W. G. Carter to Specification F.9/37 (hence the name) as a single seat fighter carrying an armament of four 0.303 in (7.7 mm) Browning machine guns and two 20 mm Hispano cannon in the nose.

A prototype (military serial number L7999) with 1,060 hp Taurus T-S(a) radials flew on 3 April 1939, and demonstrated excellent performance, its maximum speed of 360 mph being the best recorded by a British fighter at the time. Test flights revealed that the prototype was very manoeuvrable and "a delight to fly." However, after being badly damaged in a landing accident in July 1939, it was re-engined with 900 hp Taurus T-S(a)-IIIs in 1940, which resulted in a reduced performance. A second prototype (L8002) with 880 hp Rolls-Royce Peregrine I liquid-cooled in-line engines flew on 22 February 1940, albeit with no overall improvement in top speed.

A second specification for a dedicated night fighter with both nose and turret mounted guns led to Gloster submitting a design which was chiefly the F.9/37 fitted with a dorsal mounted four-gun turret (similar to that used on the Boulton Paul Defiant) and Airborne Interception (AI) radar. This received support from the Air Staff who saw it as superior to the Bristol Beaufighter and the Air Ministry ordered one of the F.9/37 to be converted to the new specification.

Unofficially known as the "Gloster Reaper", the project was terminated in the mock-up stage when concentration on other production including Gloster's work on jet aircraft meant that the foreseeable service date for the aircraft would be 1942 or later by which point the design would be outdated. Accordingly, the Reaper and F.9/37 were dropped and the de Havilland Mosquito was introduced as a night fighter.
