Comparing: T20 vs. Konštrukta T-34/100

The first in a series of 1942–1943 U.S. medium tank designs intended as replacements for the M4 Sherman. The first prototype was produced in May 1943, and trials went on until 1944. The vehicle was not approved for mass production, but subsequent prototypes, the T22 and T23, were created on the basis of this development. They, in turn, served as precursors of the T25 and T26. Eventually, the M26 Pershing emerged on their basis and was adopted for service.

Development project of the Soviet T-34-85 tank, proposed in April 1954. The Czechoslovakian variant of the vehicle was to receive a 100 mm gun and an enlarged turret. Production was planned to start in 1955; however, the work never started.
