Curtiss P-23

The Curtiss P-23 saw a major change to the design of the Hawk biplane fighter, with a totally new fuselage, tail, nose, engine and landing gear. The aircraft was built around the last production P-6E, although it didn't keep much from the original aircraft. The XP-23 was built with a metal monocoque fuselage with a very clean profile, a new metal-skinned tail, a three-blade propeller, new landing gear and a turbo-supercharged and geared G1V-1570-C engine. The largest element retained from the P-6E was the wings.

The XP-23 was delivered on 16 April 1932. As with all of the turbo-supercharged Hawks its speed as sea level fell, in this case to 178mph, while its speed at altitude rose, up to 223mph at 15,000ft.

The aircraft later had the unreliable turbo removed and a two-blade propeller installed, and became the YP-23. Although the P-23 out-performed the standard P-6E the biplane fighter was becoming obsolete and the USAAF wasn't interested in any further development of the Hawk. The Navy retained its biplanes for a little longer and the wings from the P-23 were used on the XF11C-1.
