Seversky XP-41

When, in 1936, the USAAC Materiel Division placed an order for the SEV-1XP as the P-35, it had stipulated that the 77th and last series aircraft be fitted with a more powerful supercharged engine. The chosen engine was the Pratt & Whitney R-1830-19 of 1,200hp, fitted with an integral medium-altitude two-stage mechanical supercharger. A contractual modification enabled Seversky to complete the airframe to a standard similar to that of the private-venture AP-4. The AP-9 (see Republic) was, in fact, used for competitive evaluation at Dayton in lieu of the XP-41 until the latter became available. Power plant apart, the aircraft was in virtually all respects similar to the AP-4. The XP-41 was delivered to Wright Field for USAAC evaluation in February 1939, but the Air Corps preferred the turbo-supercharged AP-4 and further development of the XP-41 was discontinued, although trials continued at Langley. This was the last of the Kartveli-designed fighters to bear the Seversky appellation, as the company thereafter became the Republic Aviation Corporation.

This prototype was built for the military, as indicated by the markings painted on it in the photograph, as well as by the fact that it received an Army Air Corps designation, "XP-41", and the fact that it was armed with machine guns. The civilian racing aircraft flown by Jacqueline Cochran was the Seversky S-2.

"Didn't Jacqilan Cochran break the East to West Trans continental record in this aircraft."
