| 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.

Anonymous, 11.09.2022 19:32 Ordered for the USAAC, basically this was the same as the AP-4 /P-43 except that the XP-41 lacked a turbo-supercharger. That made all the difference to performance at high altitudes, meaning altitudes above 15,000 feet, which was what the AP-4 /P-43 was intended for. Consequently, even though the XP-41 looked very similar, its' performance was not the same. reply | Klaatu83, e-mail, 06.07.2013 16:46 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.
