The PZL.50 Jastrząb (Hawk) was a Polish pre-war fighter aircraft designed by Wsiewołod Jakimiuk of the PZL works. The single-seat low-wing monoplane was to serve as a multi-purpose fighter and escort to replace all fighters used previously by the Polish Air Force. Designed after 1936, its prototype was first flown in February 1939. A further two prototypes were almost ready by the time of the Invasion of Poland, but the fighter did not manage to enter mass production before the war.
