Curtiss P-37


XP-37


In early 1937 the USAAC expressed an interest in furthering development of the P-36 by replacing the type's
radial powerplant with a turbosupercharged inline engine. Curtiss responded by fitting an Allison V-1710-11
with a turbosupercharger to the original Model 75 prototype... and the XP-37 was born.

The Curtiss company designation was Model 75I and, owing to the extensive modifications made to the
original airframe, it was presented to the US Army as a completely new aircraft. The Army
designated it 'XP-37' and the serial number 37-375 was assigned.

YP-37


Her days of active service at an end, this YP-37 of the 10th Air Base Squadron at Chanute
Field, Illinois was likely used as an instructional airframe for mechanics in training.

These next three photos show YP-37s flown by the 36th Pursuit Group.

The first was taken at Chanute Field... not sure of the timeframe.

This shot of YP-37 38-474 was taken by the legendary Rudy Arnold on September 26th, 1940,
presumably at Langley Field, Virginia, though I am not absolutely certain of the location.

This ship was the last of the YP-37s in active service when it was transferred to the NACA
in August of 1942. There she was used for research work, surviving 'til at least 1946.
