Curtiss XP-22

The Curtiss XP-22 was an experimental version of the P-6A Hawk that became the basis for the P-6E. It was produced using the third production P-6A Hawk (29-262). The aircraft was given a revised tail, a new nose, cantilever single strut main landing gear, had a generally cleaned-up airframe and the guns were moved from the top of the fuselage to the sides. The aircraft was originally given an annular radiator but this was later replaced with a more conventional belly radiator mounted in a tunnel beneath the rear of the engine. On 30 June 1931 this aircraft reached a top speed of 202.4mph.

The new undercarriage and modified nose were then taken from the XP-22 and installed on the YP-20 while standard P-6A equipment was re-installed on the XP-22. The XP-22 then became a P-6A, while the YP-20 became the prototype for forty-eight Y1P-22 aircraft, ordered on 10 July 1931. These were re-designated twice - first as P-6Cs and finally as P-6Es, the designation they were actually completed with.
