The Fairey Spearfish was a 1940s British torpedo bomber designed and built by Fairey Aviation for the Fleet Air Arm. It was one of the largest single-engine aircraft to ever operate from a British aircraft carrier.
Having learned the lessons of the Barracuda, the Spearfish had a much more powerful engine and an integral ASV anti-submarine radar (the external installation on the Barracuda caused problems with longitudinal stability). Problems with the Bristol Centaurus engine delayed the first flight until 5 July 1945.
