It was developed at Kharkov Factory No. 183 under the supervision of Mikhail Koshkin. The vehicle incorporated an optimal combination of the main combat characteristics—firepower, protection, and dynamics. The T-34 featured a 76 mm L-11 gun from 1938–1939, anti-projectile armor, and good mobility. Its combination of combat characteristics made it superior to all similar foreign tanks in the early stages of World War II. Afterwards, the T-34 had a profound influence on the development of Soviet and world tank-building.
