Yes that P&W Wasp played a huge part of radial engine progression during WW2.
Used for fighters, bombers, trainers and transport.
I saw one recently at Brooklands as a cut away model. Like the Wankel Rotary car engine it could be modulated to increase power.
The Double Wasp and of course the largest radial ever produced, the 70L Wasp Major.

*It appears the inline Mustang Voodoo holds the outright speed record over the modified radials, Sea Fury / Dreadnought and the Bear Cat / Rare Bear however.
