Poznámka: Note: | Viz historie typu. | In 1934 the Air Ministry issued Specification P.4/34 which called for a light bomber that could also be deployed in a close-support role. The P.4/34 design was a low-wing all-metal monoplane, powered by a Rolls-Royce Merlin engine, with a crew of two accommodated in tandem under a long-glazed canopy. Its layout was similar to Fairey's earlier Battle bomber, but the P.4/34 was smaller and had a wide track, inwards-retracting undercarriage. The aircraft was stressed for dive bombing, as required by the specification, and carried its load of two 250 lb bombs underwing (the competing Hawker aircraft had an internal bomb bay). Two Fairey P.4/34s were ordered, with the first (serial K5099) flying on 13 January 1937.[1] The Hawker prototype followed on 10 March 1937. The Hawker was deemed superior; however, the demand for a light bomber had changed, and it would enter service as a target tug. The P.4/34 would serve as the basis for a two-seat, long-range, carrier-based fighter for the Fleet Air Arm to meet the requirements of Specification O.8/38. The second prototype P.4/34 (serial K7555) was therefore modified with, among other things, a reduced-span wing and lowered tailplane as an aerodynamic prototype for the Fulmar. It was later used to test retractable Fairey-Youngman flaps to be used on the Fairey Firefly fighter. |
