Curtiss XP-40



The XP-40 was created by installing an Allison V-1710-19 liquid-cooled engine into
the tenth production P-36A, USAAC serial number 38-10. As of this time, no better written
record of the P-40 exists online than that found on Joe Baugher's excellent site.

XP-40 - Final Configuration


Looking perfectly sleek and refined, the XP-40 in her final form is distinguishable
from the initial production examples only in minor details... February 10th, 1940.

These next two photos were taken at Uplands Airport in Ottawa, Canada in May of 1940
during an evaluation of the XP-40 and a Britsh Supermarine Spitfire by the RCAF and RAF.
The XP-40 had by this time been assigned to the Air Corps Materiel Division at Wright Field.

Testbed


In later years the XP-40 was used as a testbed at Wright Field for experimental rough-field landing gear
configurations. I have no date for this first image, but it was clearly taken on or after January 1st, 1944.

These two images were taken from an Army Air Forces film dated August 19th, 1943.
