T-34 followed by T-44
Successors
In 1944, pre-war development of a more advanced T-34 tank was resumed, leading to the T-44. The new tank had a turret design based on the T-34-85's, but featured a new hull with torsion-bar suspension and transversely mounted engine; it had a lower profile than the T-34-85 and was simpler to manufacture. Between 150 and 200 of these tanks were built before the end of the war. With substantial drivetrain changes, a new turret, and 100 mm gun, it became the T-54, starting production in 1947.
