Fairey Albacore

The Fairey Albacore is a single-engine biplane torpedo bomber designed and produced by the British aircraft manufacturer Fairey Aviation. It was primarily operated by the Royal Navy Fleet Air Arm (FAA) during the Second World War.

The Albacore, popularly known as the "Applecore", was conceived as a replacement for the Fairey Swordfish, an earlier biplane introduced during the mid 1930s. It was typically operated by a crew of three and was designed for spotting and reconnaissance as well as level, dive, and torpedo bombing. First flown on 12 December 1938, the Albacore was in production between 1939 and 1943, and entered FAA service with 826 Naval Air Squadron during March 1940. The type was initially operated from land bases, being dispatched on attack missions against enemy shipping and harbours in the vicinity of the English Channel. The first operations on board an aircraft carrier commenced in November 1940.

At its height, 15 first-line FAA squadrons flew the Albacore. The type was much used in the Mediterranean, participating in the Battle of Cape Matapan, the Second Battle of El Alamein, and the landings at Sicily and Salerno. Although intended to replace the Swordfish, the Albacore served with it and was eventually retired before it, both aircraft having been replaced by a pair of monoplane designs, the Fairey Barracuda and Grumman Avenger. In addition to the FAA, the Royal Air Force (RAF) and the Royal Canadian Air Force (RCAF) operated the type.

The origins of the Albacore can be traced back to the issuing of Specification S.41/36 by the Air Ministry on 11 February 1937, as well as the earlier Specification M.7/36. The latter had sought a three-seat TSR (torpedo/spotter/reconnaissance) aircraft with which to replace the Fairey Swordfish in Fleet Air Arm (FAA) service. It was required to be capable of speeds between 58 and 183 knots while also carrying a single 18-inch Mark XIIA torpedo; furthermore, it was to be fitted with dual flight controls, have a powered rear turret, comprehensive facilities for observation and navigation, and incorporate soundproofing and heating measures.

In response, Fairey Aviation decided to work on its own design. Early activities included the wind tunnel testing of various biplane models at RAE Farnborough between November 1936 and June 1937. These tests reportedly influenced designs regarding the fitting of flaps upon the wings. The company produced both biplane and monoplane configurations to fulfil the requirement, officials dismissed the monoplane proposal as it raised uncertainties for the role it was to be tasked with at that time. Accordingly, Fairey focused its efforts onto the biplane configuration.

The Albacore, otherwise designated TBR (torpedo/bomber/reconnaissance), was a single-bay all-metal biplane. Its fuselage was of a semi-monocoque design and was equipped with a split undercarriage. In comparison to the Swordfish, the Albacore was furnished with a more powerful engine that drove a Constant-speed propeller, while the fuselage was also more aerodynamically refined. The engine that powered the early Albacores was a single Bristol Taurus II radial engine, capable of 1,065 hp, while those built later on received the more powerful Taurus XII, capable of 1,130 hp, instead.

Furthermore, the Albacore provided numerous amenities for the benefit of its crew, such as its fully enclosed cockpit, a central heating system, a windscreen wiper for the pilot, and lavatory. In the event of a water landing, the aircraft was also fitted with an automatic liferaft deployment system to assist in the crew's survival. The armament of the Albacore typically included a single fixed forward-firing machine gun in the upper starboard wing, while the rear cockpit was provided with either a single or twin Vickers K machine gun. It could carry a maximum under-wing bomb load of four 500 lb (230 kg) bombs.

The wings of the Albacore were of an equal span and were foldable for more compact stowage onboard aircraft carriers. They were covered by fabric, had relatively large flaps which were hydraulically-actuated and could also act as air brakes during dives. Like the Swordfish, it was capable of dive bombing; it could dive at speeds of up to 215 knots (400 km/h) IAS irrespective of the positioning of the flaps. According to test pilot Eric Brown, the Albacore was relatively steady throughout the dive, while the recovery was typically both smooth and relatively easy to perform.
