Curtiss AT-5

The Curtiss AT-5 was produced in an attempt to create an advanced trainer by fitting a lower powered engine in the fuselage of a standard pursuit aircraft. Forty AT-4s were ordered, powered by Wright-Hispano engines and using the fuselage of the Curtiss P-1 Hawk. The last five of these aircraft were completed with the 220hp Wright J-5 (R-790) Whirlwind radial engine. This was lighter than the Wright-Hispano engine, but the aircraft still suffered from the same problems as the AT-4, caused by matching the high performance fighter airframe with a low power engine.

Another thirty one AT-5As were built from new. These had the same 220hp engine, but used the airframe of the P-1B. The AT-5A was nearly 500lb lighter than the P-1B, but its reduced engine power meant that top speed dropped from 157.5mph down to 121.9mph. The AT-5 also handled differently to the P-1B.

As with the AT-4, the AT-5s were converted back into standard P-1s. All of the AT-4s became the P-1E while all of the AT-5A became the P-1F. During their brief training career both the AT-4s and AT-5s were used by the 43rd School Squadron (later the 43rd Fighter Squadron).
