Comparing: T-34-85M vs. AC 4 Experimental

A modification of the T-34-85 tank, produced at Factory No. 183. Unlike the original vehicle, it featured enhanced front armor and reduced rear armor. Fuel tanks were transferred from the fighting compartment to the rear. When the suspension proved faulty, production was halted after just one prototype was built.

The tank was developed in 1943. An order was placed for 400 vehicles. The prototype was created on the basis of the AC 1 tank with an enlarged superstructure, which allowed mounting a modified turret from the AC 3 tank with a 17-pounder gun. In July 1943, the work on the project was stopped at the final stage, as the program for creating the Australian cruiser tank was discontinued.
