The Fairey Battle was a British single-engine light bomber 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 earlier Hawker Hart and Hind biplanes. The Battle was powered by the same Rolls-Royce Merlin piston engine that provided various contemporary British fighters[N 1] high performance; however, the Battle was weighed down with a three-man crew and a bomb load. Despite being a great improvement on the aircraft that preceded it, by the time it saw action, the Battle was relatively slow, limited in terms of range and was quickly found to be highly vulnerable to both anti-aircraft fire and hostile fighters, possessing only two defensive .303 in machine guns.
