What was the most produced tank of World War II?

The Soviet Union produced more than 64,000 T-34 and T-34 variants between 1941 and 1945, making it the most produced tank of the Second World War. That is compared to more than 49,000 M4 Sherman and M4 variants produced during the war by the United States.

The idea of a more heavily armed and armored "universal tank" that reflected lessons learned by the Soviet Army during conflicts with Japan in the late 1930s lead designers to create the first T-34s. The term T-34 came from the lead designer Mikhail Koshkin, named it for 1934, when he first was thinking about the design of this new tank.

The T-34 had sloped armor, a relatively powerful engine and wide tracks. The initial T-34 version had a 76.2 mm gun. In 1944, a second major version began production, the T-34-85, with a larger 85 mm gun intended to counter newer German tanks.

More than 84,000 were manufactured by the time production was discontinued in 1958. As of 2012, some developing countries still employ T-34s in some armored support roles.
