Object 274aTier 8, Medium tank★ Premium tank

A prototype of a new medium tank developed in the late 1950s to replace the T-54. This vehicle was supposed to feature a standard configuration and an all-cast hull. Due to heightened requirements for nuclear survivability and its complicated design, further development was discontinued in 1960. Existed only in blueprints.
