The Curtiss-Wright XP-55 was a prototype Pursuit aircraft built to a USAAC request for proposals using unconventional designs.  The Curtiss-Wright submission was canard configuration with a rear-mounted engine driving a pusher propeller.  Its first flight was on 19JUL43.  This is a beautiful color photo of the first prototype, 42-78845, running up her engine.  (NASM Hans Groenhoff Collection)

The first prototype was the only one of the three produced to carry the mid-war U.S. national insignia with the serial numbers on the forward fuselage.

When the barred national insignia was introduced in June 1943 the serials were moved to the dorsal fin above the engine.  Finish on all the XP-55s was the USAAF standard Olive Drab over Neutral Gray with Yellow-Orange serials.  (NASM Hans Groenhoff Collection)

The intended design armament was two 20 mm cannon and two .50 caliber machine guns.  Maximum speed was 390 mph which was not an improvement over existing designs already in production at the time.  (NASM Rudy Arnold Collection)

Wind tunnel testing had warned of aerodynamic instability inherent in the design.  On 15NOV43 test pilot Harvey Gray was exploring the aircraft’s stall performance when it unexpectedly flipped onto its back and fell 16,000 feet.  Unable to regain control, Gray took to his parachute but the aircraft was a total loss.

Cockpit layout was conventional.  The canopy folded to the starboard side to allow the pilot to enter.  The propeller could be jettisoned in case the pilot had to bail out.  (Ray Wagner Collection)

The third and final Ascender was serialed 42-78847.  It was fitted with four .50 caliber guns in the nose and four-foot wingtip extensions to improve stability.  The wingtip extensions were also refitted to the second prototype.
