 By the time production was to have started, Merlin production had increased to the point where the idea was abandoned.The last major change to the Hurricane was to "rationalise" the wing, configuring it with a single design able to mount two bombs, two 40 mm (1.57 in) Vickers S guns, or eight "60 pounder" RP-3 rockets.Some sources say that the new design also mounted the improved Merlin 24 or 27 engines of 1,620 hp (1,208 kW) but this is disputed.
