The Fairey Battle was a British single-engine light bomber that was designed and manufactured by the Fairey Aviation Company. It was developed during the mid-1930s for the Royal Air Force (RAF) as a monoplane successor to the Hawker Hart and Hind biplanes. The Battle was powered by the same high-performance Rolls-Royce Merlin piston engine that powered various contemporary British fighters like the Hawker Hurricane and Supermarine Spitfire. The Battle was much heavier, with its three-man crew and bomb load. Though a great improvement over the aircraft that preceded it, the Battle was relatively slow and limited in range. With only two .303 (7.7 mm) machine guns as defensive armament, it was found to be highly vulnerable to enemy fighters and anti-aircraft fire. The Fairey Battle was used on operations early in the Second World War. During the "Phoney War" the type achieved the distinction of scoring the first aerial victory of an RAF aircraft in the conflict. In May 1940, the Battles of the Advanced Air Striking Force suffered many losses, frequently in excess of 50 per cent of aircraft sorties per mission. By the end of 1940 the type had been withdrawn from front-line service and relegated to training units overseas. As an aircraft that had been considered to hold great promise in the pre-war era, the Battle proved to be one of the most disappointing aircraft in RAF service. The Fairey Battle was a single-engine monoplane light bomber, powered by a Rolls-Royce Merlin engine. Production aircraft were progressively powered by various models of the Merlin engine, such as the Merlin I, II, III (most numerous) and V but all bomber variants were called the Battle Mk I. The Battle had a relatively clean design, having adopted a slim oval-shaped fuselage which was manufactured in two sections. The forward section, in front of the cockpit, relied mainly upon a steel tubular structure to support the weight of the nose-mounted engine; the rear section was of a metal monocoque structure comprised hoop frames and Z-section stringers which was built on jigs. The structure of the aircraft involved several innovations and firsts for Fairey, it had the distinction of being the company's first low-wing monoplane; it also was the first light-alloy stressed-skin construction aircraft to be produced by the firm. The wing of the Battle used a two-part construction, the centre section being integral with the fuselage. The internal structure of the wings relied upon steel spars which varied in dimension towards the wing tips; the ailerons, elevators and rudder all were metal-framed with fabric coverings, while the split trailing edge flaps were entirely composed of metal. The Battle served as a trainer with the Royal Australian Air Force (RAAF), which allocated it the prefix A22. On 30 April 1940, the first four RAAF Battles were delivered to No. 1 Aircraft Depot; on 29 June 1940, the first assembled aircraft, P5239, conducted its first flight. Deliveries occurred at a steady pace until the last Battle was received on 7 December 1943. These aircraft were a mix of bomber, target tug, and dual-control trainer variants; they were mainly used by Bombing and Gunnery schools until 1945; the last aircraft were phased out in 1949. A total of 2,201 Battles were built, with 366 serving in the RAAF. For further information on the origins, design, operational history and variants, click here.
