Design and development

The Hawker Fury was a development of the earlier Hawker F.20/27 prototype fighter, replacing the F.20/27's radial engine 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.^[1] 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 .^[2] It 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.^[3]
The Hornet was purchased by the Air Ministry at the start of 1930, and was subject to further evaluation, with a small initial production order for 21 aircraft (to be designated Hawker Fury - as the Air Ministry wanted fighter names that "reflected ferocity") placed during 1930.^[1] The Fury I made its maiden flight at Brooklands with chief test pilot George Bulman at the controls on March 25, 1931.^[4]
The Fury was the RAF's first operational 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, and powered by a 690 hp (515 kW) Mk4 Kestrel engine. These improvements gave improved speed and rate of climb.
Designer at Hawker, Sidney Camm, designed a monoplane version of the Fury in 1933. It was not developed until the Rolls-Royce developed what was to become their famous Merlin engine. The design was then revised according to Air Ministry specification F5/34 to become the prototype Hawker Hurricane.

Operational history

The Fury I entered squadron service with the RAF in May 1931, re-equipping No. 43 Squadron. Owing to financial limitations owing to the Great Depression, only relatively small numbers of Fury Is were ordered, the type equipping only three squadrons, with the slower Bristol Bulldog equipping the bulk of the RAF's fighter squadrons.^[1] The Fury II entered service in 1936-1937. Furies remained in front line service with the RAF until 1939, replaced with, amongst other designs, Gloster Gladiators and Hawker Hurricanes, but continued to be used for training purposes.^[5]
The Fury was exported to several customers, being supplied with a variety of engines, including Kestrels, Hispano Suiza and Lorraine Petrel vee-type engines, Armstrong Siddeley Panther, Pratt & Whitney Hornet and Bristol Mercury radials.
Three Furies were ordered by Spain in 1935, it being intended to produce another 50 under licence. The Spanish variant had a cantilever undercarriage design with Dowty internally-sprung wheels, similar to that used on the Gladiator, and was powered by a 612 hp (457 kW) Hispano Suiza 12Xbr engine,^[6] reaching a speed 234 mph (377 km/h).^[7] The three Furies were delivered without armament on 11 July 1936, just before the outbreak of the Spanish Civil War. They were taken into service by the Spanish Republican Air Force, being fitted with machine guns scrounged from crashed aircraft. One Fury made a forced landing behind enemy lines due to a lack of fuel and was repaired by the Nationalists, although it was not used operationally,^[8] while the Republicans used one of the Furies in the defence of Madrid until wrecked in a crash in November 1936.^[9]
Although phased out from RAF squadrons, the Fury was still used by some foreign air forces in the early 1940s; Yugoslav Furies saw action against Axis forces in the German invasion of 1941.^[10] On 6 April 1941 a squadron of Furies took off to defend their country against the invading German Messerschmitt Bf 109Es and Messerschmitt Bf 110s. In the resulting conflict 10 Furies were destroyed, almost the entire squadron. CO of the 36 LG was Major Franjo Đzal and that morning avoided take off and watched from the ground as his men were slaughtered in their obsolete biplane fighters. In an unequal battle against superior adversaries ten Furies, five still on the ground in the process of taking off were shot down and eight pilots killed. Two more Furies and Bücker Bü 131 were destroyed on the ground. But of the attacking German aircraft 7 failed to return: 5 Bf-109s and 2 Bf-110s, though it is possible that some of them were non-combat losses. However, it is certain that at least one of them was lost to ramming by a Fury. The other squadron of Yugoslav Furies active at the time of the invasion strafed enemy tanks and ground forces, some being lost to ground fire and one being destroyed in a dogfight with a Fiat CR.42. The rest of the Yugoslav Furies were destroyed when they became unserviceable or at the time of Armistice on the 15th.^[11] Ex-RAF Furies were also used by the South African Air Force against the Italian forces in East Africa in 1941 and despite their obsolescence destroyed 2 Caproni bombers as well as strafing many airfields, destroying grounded fighters and bombers.^[12]
A total of 262 Furies were produced, of which 22 served in Persia, 3 in Portugal, at least 30 in South Africa, 3 in Spain, at least 30 in Yugoslavia and the remainder in the United Kingdom.

Variants

Hawker Hornet (Fury prototype)

Hawker Hornet: Single-seat fighter prototype. Powered by a Rolls Royce F.XIA and later by a 480 hp (358 kW) F.XIS. Only one was built. This aircraft was slightly smaller and lighter than the Fury and considered by Hawkers as a separate type.^{[citation needed]}
Fury Mk I: Single-seat fighter version, powered by a 525 hp (391 kW) Rolls Royce Kestrel IIs piston engine.
Fury Series 1A: Single seat fighter for Yugoslavia, similar to Fury Mk I and powered by Kestrel IIS piston engine. Six built by Hawker. One was delivered fitted with a 500 hp (373 kW) Hispano-Suiza 12 NB engine, with poorer performance, and was re-fitted with a Kestrel,^[13]^[14] while a second was later used for trials with a 720 hp (537 kW) Lorraine Petrel HFrs engine.^[15]
Intermediate Fury: Test and trails aircraft, used as a prototype; one built, British civil registration G-ABSE.
High Speed Fury: Private venture. Single-seat high-speed trials and test aircraft, used as a prototype, which was developed into the Fury Mk II; one built.
