The Spitfire and Hurricane both uses the Merlin. As did the Mosquito. The Mustang had a later version, but still a Merlin.

Merlin engines sound bloody amazing. We had a Hurricane and a Spitfire doing circuits around our street a couple of years ago about 200 feet up. Words fail me!

The Mustang had a later version, but still a Merlin.

But wasn't the Mustang's engine the improved version of the Merlin licensed to be built by Packard?

I believe Packard's Detroit engines were used on several of England's longer range bombers.
