Aleksander Siewierski, originally from Georgia, was in the United States in 1917 and was there when the revolution in Russia broke out. As Alexander Seversky, he founded the Seversky Aero Corporation. Alexander Kartvelli (also a Georgian) became his main designer. Unfortunately, financial problems led to firing Seversky, and his company changed its name to Republic Aviation Corporation. The projects started and developed by Seversky, which resulted in the P-35 fighter, were continued, though. As a result of its further development, a design for the XP-41 high-altitude fighter equipped with a turbocharger was prepared. Only a prototype was built, while many of its solutions went to a more advanced aircraft, designated AP-4, and finally P-43. drawing sheets, colour profiles
