The Fury Monoplane was a proposed adaptation of the successful Hawker Fury biplane, developed by Sydney Camm in 1933. It would be powered by the Royals Royce Goshawk engine (capable of providing 660hp). It would retain the fixed undercarriage of the original Hawker Fury, and be armed with four machine guns. However, Rolls-Royce were already working on the engine that would eventually become the Merlin, and so Camm abandoned work on the Fury in favour of designing a new aircraft around the new engine. That aircraft, first known as the Interceptor Monoplane, would develop into the Hawker Hurricane.
