The Hawker Fury is a British biplane fighter aircraft used by the Royal Air Force in the 1930s. It was a fast, agile aircraft, and the first interceptor in RAF service capable of speed higher than 200 mph (321 kmh). It was the fighter counterpart to the Hawker Hart light bomber. Design and development The Hawker Fury was a development of the earlier Hawker F.20/27 prototype fighter, replacing the radial engine of the F.20/27 with the new Rolls-Royce F.XI V-12 engine (later known as the Rolls-Royce Kestrel), which was also used by Hawker's new light bomber, the Hawker Hart. The new fighter prototype, known as the Hawker Hornet, first flew at Brooklands, Surrey, in March 1929. The Hornet was a single-engined biplane, with single bay wings, initially powered by a 420 hp (313 kW) Rolls-Royce F.XIC engine enclosed by a smooth, streamlined cowling but was quickly re-engined with a 480 hp (358 kW) Kestrel IS. The prototype was evaluated against the similarly powered Fairey Firefly II, being preferred because of its better handling and its all metal structure, compared with the mainly wooden construction of the Firefly. The Hornet was purchased by the Air Ministry at the start of 1930 and was subject to more tests, with a small initial production order for 21 aircraft (to be called Hawker Fury – as the Air Ministry wanted fighter names that "reflected ferocity") placed during 1930. The Fury I made its maiden flight at Brooklands, with chief test pilot George Bulman at the controls, on 25 March 1931. The Fury was the first operational RAF fighter aircraft to be able to exceed 200 mph (322 km/h) in level flight. It had highly sensitive controls which gave it superb aerobatic performance. It was designed partly for the fast interception of bombers and to that end it had a climb rate of almost 2,400 ft/min (730 m/min, powered by a 525 hp/391 kW Kestrel engine). An experimental prototype, the High Speed Fury, was built to test design features for Hawker's planned competitor for the F.7/30 fighter competition (the Hawker P.V.3) as well as for more general development. While the P.V.3 was unsuccessful owing to the use of the unreliable evaporatively cooled Rolls-Royce Goshawk engine, many of the improvements tested on the High Speed Fury were incorporated in an improved Fury II, with a cleaned up airframe and reduced drag, powered by a 690 hp
