The Seversky XP-41 was a fighter aircraft built in the United States in 1939. A single prototype was modified from the last production Seversky P-35 by adding a new streamlined canopy, a Pratt & Whitney R-1830-19 engine with a two-speed supercharger, and revised landing gear. The XP-41 first flew in March 1939. The aircraft was developed in parallel with the P-43 Lancer, and work was stopped when the USAAC showed a preference for the latter.
