The SEV-2XP (the designation indicating 2-seat experimental Pursuit) designed by Alexander Kartveli was a derivative of the first product of the Seversky Aircraft Corporation, the commercial SEV-3 three-seat monoplane.
An all-metal semi-monocoque aircraft with a fixed spatted undercarriage, the SEV-2XP was flown in the spring of 1935 with the unsatisfactory Wright R-1670 14-cylinder radial offering 735hp for take-off. Provision was made for an armament of two synchronised machine guns, one of 7.62mm and the other of 12.7mm, and one 7.62mm gun on a flexible mount in the rear cockpit.
In May 1935, the USAAC Material Division initiated a contest for a new single-seat fighter. Maj Alexander P de Seversky, believing the SEV-2XP capable of out-performing any single-seat fighter, entered this aircraft as a contender. In the event, the SEV-2XP was damaged in an accident on 18 June while en route to the contest. It was then returned to the manufacturer and reworked as the single-seat SEV-1XP.
