Fairey Firefly. The Fairey Firefly is a Second World War-era carrier-borne fighter aircraft and anti-submarine aircraft that was principally operated by the Fleet Air Arm (FAA). It was developed and built by the British aircraft manufacturer Fairey Aviation Company.

Development of the Firefly can be traced back to pair of specifications issued by the British Air Ministry in 1938, calling for new naval fighter designs. Designed to the contemporary FAA concept of a two-seat fleet reconnaissance/fighter, the pilot and observer were positioned at separate stations. In flight, the Firefly was superior in terms of both performance and firepower to its predecessor, the Fairey Fulmar. Due to a protracted development, the type only entered operational service towards the end of the conflict, at which point it was no longer competitive as a fighter. The limitations of a single engine in a relatively heavy airframe reduced its performance, but the Firefly proved to be a fairly sturdy, long-ranged, and docile aircraft during carrier operations.

The Fairey Firefly served in the Second World War as a fleet fighter. During the post-war era, it was soon superseded in the fighter role by the arrival of more modern jet aircraft, thus the Firefly was adapted to perform in other roles, including strike operations and anti-submarine warfare. In these capacities, it remained a mainstay of the FAA until the mid-1950s. Both British and Australian Fireflies routinely performed ground–attack operations from various aircraft carriers during the Korean War. In foreign service, the type was in operation with the naval air arms of Australia, Canada, India and the Netherlands. As late as 1962, Dutch Fireflies were used to carry out attack sorties against Indonesian infiltrators in Dutch New Guinea. Its final uses were in various secondary roles, such as trainers, target tugs and drone aircraft.

Design and development

During 1938, by which point British authorities were preparing for the likelihood of a great war, the Air Ministry issued a pair of specifications calling for naval fighters, a conventional and a "turret fighter". The performance requirements for both was to be able to attain a speed of  while flying at  and carrying an armament, for the conventional fighter, of eight  Browning machine guns or four  Hispano cannon. This aircraft would replace the Fairey Fulmar, which had been viewed as an interim design. These specifications were updated during the following year, while several British manufacturers tendered their ideas. Further changes to the official specification followed, such as the turret fighter specification being eliminated, while a modified specification was issued to cover single and dual-seat fighters capable of  respectively. Fairey offered designs that could accommodate either a single or twin-seat arrangements, either powered by the Rolls-Royce Griffon engine, or combining a larger airframe with a Napier Sabre engine. After consideration of the manufacturer's responses, Specification N.5/40 replaced the earlier specifications. Due to the necessity of navigating over open sea, it was decided to opt for a two-seater aircraft alone. For defence of naval bases, a separate single seater design would lead to the Blackburn Firebrand.

The Firefly was designed by a team led by H.E. Chaplin at Fairey Aviation which reportedly used the Fulmar as a starting point. During June 1940, the Admiralty placed an initial order for 200 aircraft "off the drawing board", the first three of which were to function as prototypes. On 22 December 1941, the first prototype of the Firefly performed its maiden flight. Although the aircraft was  heavier than the preceding Fulmar (largely due to the adoption of the heavier Griffon engine and the armament of two  Hispano cannon in each wing), the Firefly was  faster due to improved aerodynamics, as well as the increased power of the Griffon IIB engine, being capable of generating a maximum of .

The Firefly was a low-wing cantilever monoplane, featuring an oval-section metal semi-monocoque fuselage and a conventional tail unit with forward-placed tailplane. It was powered by a Rolls-Royce Griffon liquid-cooled piston engine, which drove a four-blade Rotol-built propeller. A large chin-mounted radiator was present to provide cooling for the engine. The Firefly had retractable main undercarriage and tail wheel, the hydraulically-actuated main landing gear retracting inwards into the underside of the wing centre-section. This undercarriage was widely-set, a highly useful feature for carrier landings. The aircraft was also fitted with a retractable arrester hook mounted underneath the rear fuselage. The pilot's cockpit was located above the leading edge of the wing while the observer/radio-operator/navigator was positioned aft of the wing's trailing edge. These positions provided better visibility for operating and landing, and both crew were provided with separate jettisonable canopies.

The Firefly was equipped with an all-metal wing which could be folded manually, the wings ending up along the sides of the fuselage when folded. When in the flying position, the wings were hydraulically locked in place. The wing itself featured square tips and large Fairey-Youngman flaps, which provided relatively good handling while flown at low speeds. A total of four 20mm cannon were buried within the wings, which was considered to be relatively heavy armament for the era. According to pilots, the general handling of the Firefly was relatively well-balanced, but a level of physical strength was required to effectively execute aerobatics.

During 1942, handling and performance trials were first undertaken at RAF Boscombe Down by Admiralty test pilots Mike Lithgow and Roy Sydney Baker-Falkner. By 1944, the Firefly had been cleared to use underwing rocket projectiles and, by April 1944, tests involving a double-underwing load of 16 rockets and a pair of  drop tanks still provided acceptable handling. Further testing with two 90 gallon (410 L) drop tanks or two  bombs deemed acceptable albeit with "...a small adverse effect on handling..." while "...handling with a single  bomb was unpleasant, but manageable." Performance trials at  indicated a maximum speed of  at  while a climb to  took 12.4 minutes, with a maximum climb rate of  at , and a service ceiling of .

Operational history

The primary variant of the aircraft used during the Second World War was the Firefly Mk I, which was used in all theatres of operations. During March 1943, the first Firefly Mk Is were delivered to the FAA but these did not enter operational service until July 1944, at which point they equipped 1770 Naval Air Squadron aboard . The first operations were flown in the European theatre where Fireflies carried out numerous armed reconnaissance flights and anti-shipping strikes along the Norwegian coast. That year, Fireflies also provided air cover and aerial reconnaissance during attacks on the German battleship .

Throughout its operational career, the Firefly took on increasingly demanding roles from fighter to anti-submarine warfare while being stationed mainly with the British Pacific Fleet in the Far East and Pacific theatres. The type was used against Japanese ground targets and fighter aircraft. FAA Fireflies carried out attacks on oil refineries and airfields and was repeatedly dispatched against Japanese-controlled islands up until Victory over Japan Day. The Firefly gained a level of public renown when the type became the first British-designed and -built aircraft to overfly the Japanese capital of Tokyo.

During May 1945, in anticipation of a major naval offensive against the Japanese mainland, the Canadian government accepted a British offer to loan a pair of Colossus-class aircraft carriers to the Royal Canadian Navy. To equip these carriers, it was necessary to procure naval fighters. Based upon the feedback of veteran pilots, Canada opted to acquire the Firefly over opposition that favoured procuring American aircraft instead. As a stop-gap measure, Royal Navy Fireflies were loaned while more advanced purpose-built aircraft were being constructed. Between 1946 and 1954, the Canadian Navy employed 65  AS Mk.5 Fireflies on its aircraft carriers. The service also flew a handful of Mk.I Fireflies. During the 1950s, Canada decided to sell off its Fireflies and buyers included the armed forces of Ethiopia, Denmark, and the Netherlands.

After the Second World War, the Firefly remained in front line service with the Fleet Air Arm, continuing in this capacity until the mid-1950s. During this time, British-built Fireflies were also supplied to a number of overseas nations, including Canada, Australia, Denmark, Ethiopia, the Netherlands, India and Thailand.

During 1947, the Australian government approved of formation of the Royal Australian Fleet Air Arm and the acquisition of a pair of s from Britain. Following a consultation with the Royal Navy, the Royal Australian Navy (RAN) opted to procure both the Firefly and the Hawker Sea Fury to equip its new aircraft carriers. These two types formed the backbone of the newly formed Australian Carrier Air Groups (CAGs), which would operate a total fleet size of 108 Fireflies, acquired across multiple orders. The first aircraft was delivered in May 1949, and the final Firefly arrived during August 1953. aircrew training predominated in early RAN operations ahead of achieving operational status during 1950.

During the Korean War of the 1950s, both British and Australian Fireflies carried out anti-shipping patrols and ground strikes from various aircraft carriers positioned offshore. Additional missions roles including anti-submarine patrols and aerial observation, as well as assisting battleships in providing effective naval gunfire support. Numerous FAA Fireflies were loaned to the Australian Navy during the conflict as many of its aircraft did not feature cannons when configured for anti-submarine warfare. Despite several incidents of aircraft being struck by anti-aircraft fire, the Firefly proved to be relatively rugged. The type was routinely used for strike operations against targets such as bridges and railway lines to damage North Korean logistics and communications. As the war went on, pilots developed new low-level dive-bombing techniques to achieve greater accuracy. Combat use of the Firefly in the theatre continued until the signing of the Korean Armistice Agreement on 27 July 1953, although post-armistice patrols involving the type continued for several years afterwards.

FAA Fireflies were again deployed in the Far East amid the Malayan Emergency, where it was used to conduct ground-attack operations against Malayan Communist Party insurgents. The Firefly's front line career with the FAA came to an end shortly following the introduction of the newer and larger Fairey Gannet, which effectively replaced the type. The RAN also decided to relegate their Fireflies to secondary duties following the adoption of newer aircraft, such as the Gannet and the jet-powered de Havilland Sea Venom. Several versions of the type were developed later in its career to serve in a number of secondary roles, including as trainers, target tugs and drone aircraft. As an example, the Indian Navy acquired a batch of 10 aircraft during the mid-1950s for target tug purposes. By the end of the 1950s, many operators were disposing of their remaining Fireflies, typically as scrap.

In the late 1940s, the Royal Netherlands Navy deployed a Firefly squadron to the Dutch East Indies, as part of the forces countering Indonesian nationalists. When talks broke down in July 1947, the Dutch launched multiple air strikes. Three Fireflies were shot down by ground fire. During 1960, in response to territorial demands and threats issued by Indonesia, the Netherlands chose to deploy a number of Firefly AS.Mk 4s to Dutch New Guinea. As Indonesian forces began to retake the territory, the Fireflies carried out attack operations during early 1962. These strikes continued until the Royal Netherlands Navy withdrew following the negotiation of a political settlement between the two countries.

Operators

Surviving aircraft

There 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 holds VH127, a TT4, which is on public display at Yeovilton.

The Imperial War Museum owns one of the oldest surviving Fireflies, serial number Z2033. Built as a MkI in 1944, Z2033 was used originally used by the RNAS for aircraft landing trials, then by Fairey for spin trials. Z2033 was converted to target tug designation and operated in Sweden in the 1950s in this role. The aircraft returned to the UK in 1964 to go on display at the Skyframe Aircraft Museum, and was acquired by Imperial War Museum in 1979. The museum returned Z2033 to its original MkI configuration, and repainted the aircraft as 'DK431' of 1771 Naval Air Squadron, as operated in the Pacific in July 1945. Z2033 was loaned to the Fleet Air Arm Museum for display between 2000 and August 2023, but the aircraft is now on display again at 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 two airworthy Fireflies at present:
 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 WB518, another former RAN machine, now in the USA. (Damaged at the Wings Over Gillespie Airshow in June 2012, with restoration to airworthiness completed).
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.WB518 as of July 2015 was then undergoing extensive rebuilding and is now in flying condition out of Gillespie Field, El Cajon, California.

Other survivors include – in Australia:
 AS 5 VX388 is owned by the currently closed to public access Camden Museum of Aviation at Harrington Park, New South Wales.
 AS 6 WD826 is displayed at the Royal Australian Navy's Fleet Air Arm Museum (Australia). This Firefly was restored to airworthy condition in the 1980s and flew for three years before its return to the museum.
 AS 6 WD827 which was once owned by the Australian Air League, Blacktown, New South Wales, 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 repainted as WB518 which was the original aircraft displayed in Griffith but is now the flying example restored by Captain Kurdziel. The swap was made in 1991.
 AS 6 WJ109 is stored for eventual exhibition at the Australian War Memorial, Canberra. This aircraft was previously at the Fleet Air Arm Museum (Australia), Nowra, New South Wales.

The Royal Thai Air Force Museum in Bangkok, Thailand has a Firefly Mk I on display.

A sole remaining Firefly of the 10 acquired by India is displayed at the Naval Aviation Museum in Goa.

Two ex-Swedish Fireflies moved to IWM Duxford, Cambridgeshire in 2003. Acquired by the Aircraft Restoration Company, they were in Royal Navy service from 1944 and 1946, and then converted to target tugs for gunnery training in 1950 and 1954. One is being restored to flying condition, and the other was traded to the Aviodrome Museum in the Netherlands for a Spitfire.

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 in exchange for medical supplies.

AS 6 WD833, another ex-Australian Firefly, is owned by Henry "Butch" Schroeder who moved the aircraft to Danville, Illinois, USA for restoration. The present whereabouts of this aircraft are unclear.
