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 Rolls-Royce F.XIC engine enclosed by a smooth, streamlined cowling but was quickly re-engined with a 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 was the first operational RAF fighter aircraft to be able to exceed 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 could climb to in 4 minutes 25 seconds, powered by a 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 Mk4 Kestrel engine, which gave improved speed and rate of climb.
Sydney Camm designed a monoplane version of the Fury in 1933. It was not developed until
Rolls-Royce produced what became their famous
Merlin engine. The design was then revised according to Air Ministry specification
F5/34 to become the prototype
Hawker Hurricane. ==Operational history==
