A YP-37 of the 32nd Pursuit Squadron at Chanute Field, Illinois, 1940
Curtiss YP-37, an experimental variant of the P-36, with a supercharged inline Allison engine.Â
The powerplant’s unreliability, as well as visibility problems from the rear-set cockpit, led this project to be cancelled in favor of the more conventional, if un-supercharged P-40. A total of 14 P-37s were built.
