One of the most famous piston-engined fighter aircraft of all time, it saw use in all the theaters of WWII, including on the Eastern Front. It was adopted by 26 countries and used in USSR under the Lend-Lease Act. Many famous pilots of different nations piloted this plane, including Soviet pilots Boris Safonov, Pyotr Pokryshev, Fedor Chubukov and others. This isn’t the nimblest fighter, but it compensates with sturdy construction and very powerful armament consisting of six (6) .50 cal. machine guns.
