Camm's initial submission in response to F.7/30, the Hawker P.V.3, was essentially a scaled-up version of the Fury biplane. However, the P.V.3 was not among the proposals which the Air Ministry had selected to be constructed as a government-sponsored prototype. After the rejection of the P.V.3 proposal, Camm commenced work upon a new design involving a cantilever monoplane arrangement, complete with a fixed undercarriage, armed with four machine guns and powered by the Rolls-Royce Goshawk engine. The original 1934 armament specifications for what would evolve into the Hurricane were for a similar armament fitment to the Gloster Gladiator: four machine-guns, two in the wings and two in the fuselage, synchronised to fire through the propeller arc. By January 1934, the proposal's detail drawings had been finished, but these failed to impress the Air Ministry enough for a prototype to be ordered.
