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.
