What would the effects be of the British developing the Westland Whirlwind with Rolls-Royce Merlin engines instead of RR Peregrines?
Merlins were more powerful and reliable than Peregrines, but all the Merlin production was used for Hurricane and Spitfire production. So suppose that the British built less Hurricanes and Spitfires, and more Whirlwinds with the Merlin engine instead.
