Fairey Firefly

For the British single-seat biplane fighter of the 1930s, see Fairey Firefly II.

The Fairey Firefly was a British Second World War-era carrier-borne fighter aircraft and anti-submarine aircraft of the Fleet Air Arm (FAA).

It was superior in performance and firepower to its predecessor, the Fulmar, but only entered operational service towards the end of the war. Designed around the contemporary FAA concept of a two-seat fleet reconnaissance/fighter, the pilot and navigator/weapons officer were housed in separate stations. The design proved to be sturdy, long-ranging and docile in carrier operations, although the limitations of a single engine in a heavy airframe reduced overall performance.

The Fairey Firefly served in the Second World War as a fleet fighter but in postwar service, although it was superseded by more modern jet aircraft, the Firefly was adapted to other roles, including strike operations and anti-submarine warfare, remaining a mainstay of the FAA until the mid-1950s. Both the UK and Australia Fireflies flew ground attack operations off various aircraft carriers in the Korean War. In foreign service, the type was in operation with the naval air arms of Australia, Canada, India, and the Netherlands whose Fireflies carried out a few attack sorties as late as 1962 in Dutch New Guinea. {| class="toc" id="toc"

Design and development
Before the war, in 1938 the Air Ministry issued two specifications for two naval fighters, a conventional and a "turret fighter". Performance for both was to be 275 knots at 15,000 ft while carrying an armament, for the conventional fighter, of eight 0.303 Browning machine guns or four 20mm Hispano cannon. This would replace the Fulmar which had been an interim design. These specifications were updated the following year and several British manufacturers tendered their ideas. Further changes to the official specification followed, the turret fighter specification was dropped and a modified specification issued to cover single and dual seat fighters capable of 330 and 300 knots respectively. Fairey offering designs that could be single or two seater and powered by the Rolls Royce Griffon or alternatively a larger airframe with a Napier Sabre. After consideration of manufacturers responses, Specification N.5/40 replaced the earlier specifications. Due to the necessity of navigating over open sea, it was for a two-seater alone.[1] For defence of naval bases a separate single seater design would lead to the Blackburn Firebrand.[2]

The Firefly was designed by H.E. Chaplin at Fairey Aviation; in June 1940, the Admiralty ordered 200 aircraft "off the drawing board" with the first three to be the prototypes. The prototype of the Firefly flew on 22 December 1941.[3] Although it was 4,000 lb (1,810 kg) heavier than the Fulmar (largely due to its armament of two 20 mm Hispano cannon in each wing), the Firefly was 40 mph (60 km/h) faster due to improved aerodynamics and a more powerful engine, the 1,735 hp (1,294 kW) Rolls-Royce Griffon IIB.

The Firefly is a low-wing cantilever monoplane with oval-section metal semi-monocoque fuselage and conventional tail unit with forward-placed tailplane. Powered by a Rolls-Royce Griffon liquid-cooled piston engine with a three-blade airscrew. The Firefly had retractable main landing gear and tail wheel, with the hydraulically operated main landing gear retracting inwards into the underside of the wing centre-section. The aircraft also had a retractable arrester hook under the rear fuselage. The pilot's cockpit was over the leading edge of the wing and the observer/radio-operator/navigator aft of the wing trailing edge - positions which gave better visibility for operating and landing. Both crew had separate jettisonable canopies. The all-metal wing could be folded manually, with the wings ending up along the sides of the fuselage. When in the flying position, the wings were hydraulically locked.[4]

Handling and performance trials were first undertaken at Boscombe Down in 1942; by 1944 the Firefly was cleared to use underwing rocket projectiles and by April 1944 tests with a double underwing load of 16 rockets and two 45 gallon (205 l) drop tanks still provided acceptable handling.[5] Further testing with two 90 gallon (410 l) drop tanks or two 1,000 lb (454 kg) bombs showed acceptable handling, albeit with "...a small adverse effect on handling..." while "...handling with a single 1,000 lb (454 kg) bomb was unpleasant, but manageable."[5] Performance trials at 11,830 lb (5,366 kg) indicated a maximum speed of 315 mph (508 km/h) at 16,800 ft (5,121 m); a climb to 20,000 ft (6,096 m) took 12.4 minutes, with a maximum climb rate of 2,140 fpm (10.87 m/s) at 3,800 ft (1,158 m), and a service ceiling of 30,100 ft (9,174 m).[6]

Operational service
Firefly FR.4 of the Netherlands Navy in 1952Firefly U.8 target drone aircraft in 1955The primary variant of the aircraft used during the Second World War was the Mk I, which was used in all theatres of operation. In March 1943, the first Firefly Mk Is were delivered but they did not enter operational service until July 1944 when they equipped 1770 Naval Air Squadron aboard HMS Indefatigable. The first operations were in Europe where Fireflies carried out armed reconnaissance flights and anti-shipping strikes along the Norwegian coast. Fireflies also provided air cover during strikes on the German battleship  Tirpitz  in 1944.

Throughout its operational career, the Firefly took on increasingly more demanding roles from fighter to anti-submarine warfare stationed mainly with the British Pacific Fleet in the Far East and Pacific theatres. Fireflies carried out attacks on oil refineries and airfields and gained renown when they became the first British-designed and -built aircraft to overfly Tokyo.[7]

After the Second World War, the Firefly remained in front line service with the Fleet Air Arm until the mid 1950s The UK also supplied the aircraft to Canada, Australia, Denmark, Ethiopia, the Netherlands Naval Aviation Service, India and Thailand. The Royal Canadian Navy employed 65 Fireflies of the Mk AS 5 type onboard its own aircraft carriers between 1946 and 1954. It also had some Mk I Fireflies, and sold several additional examples of these to Ethiopia in the early 1950s.

British and Australian Fireflies carried out anti-shipping patrols and ground strikes off various aircraft carriers in the Korean War as well as serving in the ground-attack role in the Malayan Emergency. The Firefly's FAA front line career ended with the introduction of the Gannet. Several versions of the type were developed later in its career to serve as trainers, target tugs and drone aircraft. As an example, the Indian Navy acquired 10 aircraft in the mid-50s for target tug purposes.[8]

In 1960, in response to Indonesian territorial demands and threats, the Netherlands deployed Firefly AS.Mk 4s to Dutch New Guinea. As Indonesian forces began to infiltrate the territory, the Fireflies carried out a few attack operations in early 1962, before a political settlement was negotiated.[9]

Variants

Survivors
Firefly TT.6 on display in Griffith, AustraliaThere are approximately 24 Fairey Fireflies surviving worldwide, including three airworthy examples and at least one other being restored to flying condition. The Fleet Air Arm Museum possesses two Fireflies, the latest acquisition arriving in 2000 from the Imperial War Museum Duxford. Firefly WB271 was destroyed in July 2003 during an aerobatic air display at the Imperial War Museum in Duxford, Cambridgeshire - Europe's largest display of vintage warplanes. There are three airworthy Fireflies at present: WB518 was one of the first 10 Mk 6s built, but retained the earlier Mk 5 fuselage. It was originally delivered to the Royal Australian Navy's 817 Squadron and then served in 816 Squadron before being retired and ending up as a memorial on a pole in Griffith, New South Wales, Australia. WB518 was then purchased by American Eddie Kurdziel, a Northwest Airlines captain and former U.S. Navy pilot. WD518 was extensively restored and made its first public appearance at Oshkosh in 2002. Restoration of WD518 used parts salvaged from WD828 which was written off after a crash into a cabbage field in Camden, New South Wales in 1987.[citation needed]
 * AS 6 WH632, which was damaged in a crash and has since been restored to flying condition (painted as an RCN Firefly AS 5), is at the Canadian Warplane Heritage Museum (Canada)
 * AS 6 WD826 at the Royal Australian Navy Historic Flight, NAS Nowra NSW (Australia)
 * AS 6 WB518, another former RAN machine, now in the USA. (Damaged at the Wings Over Gillespie Airshow in June 2012, airworthiness currently unknown)

Other survivors include - in Australia: The Royal Thai Air Force Museum in Bangkok, Thailand has a Firefly Mk I on display.[14]
 * AS 6 WD827 which was once owned by the Australian Air League, Blacktown, New South Wales, and is now on display in the Australian National Aviation Museum, Melbourne, Victoria
 * AS 6 WD828 is displayed on a pole outside the Returned Services Leagues Club in Griffith, Australia. It has been re-painted as WB518 which was the original aircraft displayed in Griffith but is now the flying example owned by Captain Kurdziel. The swap was made in 1991<sup class="Template-Fact" style="white-space: nowrap;">[citation needed]
 * AS 6 WJ109 is on display at Australia's Museum of Flight, Nowra, NSW
 * AS 6 WD833, another ex-Australian Flying, is owned by Henry "Butch" Schroeder who moved the aircraft to Danville, Illinois, USA for restoration. The present whereabouts of this aircraft are unclear.

A sole remaining Firefly of the 10 acquired by India is displayed at the Naval Aviation Museum in Goa.<sup class="reference" id="cite_ref-bharatrakshak_9-1">[10]

An ex-Swedish Firefly has recently (October 2011) appeared in a hangar at the IWM Duxford, Cambridge. It is believed to be a former target tug brought to the UK for restoration to flying condition.

As well as the Canadian Warplane Heritage's ex-Australian Firefly, two other Fireflies are known to exist in Canada: one is at the Canada Aviation and Space Museum in Ottawa and another is being restored at the Shearwater Aviation Museum at Eastern Passage (near Dartmouth), Nova Scotia. Both are Mk I models that served in the Canadian Navy from 1946 to 1954, after which they were sold to the Ethiopian Air Force. Following their discovery in the Ethiopian desert in 1993, they were repatriated to Canada.
