The Boeing XP-32 was the designation given to a un-built version of the YP-29 that would have been powered by a 700hp Pratt & Whitney engine.
The YP-29 was an improved version of the Boeing P-26 'Peashooter', developed in 1934. The P-26 was the first monoplane fighter to enter USAAC service, but it was a transitional design, with braced wings, a fixed undercarriage and an open cockpit.
The YP-29 used the fuselage and engine of the P-26 but with cantilevered wings that eliminated the external bracing and a retractable undercarriage. Three prototypes were built, two with cockpit canopies and one with an open canopy. They were powered by the Pratt & Whitney R-1340 Wasp engine. The YP-29 wasn't much of an improvement over the P-26 and didn't enter production.
The designation XP-32 was allocated to a 1934 version of the YP-29 that would have been powered by a 700hp Pratt & Whitney R-1525-1 twin-row radial engine. It would have been a low winged monoplane with a enclosed cockpit and tapered wings with a straight leading edge and curved trailing edge. The aircraft was never built but the retractable landing-gear designed for it was later used in the Brewster F2A-1 fighter.
