Comparing: AC 4 Experimental vs. Type 58

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.

The U.S.S.R. exported a total of 1,800 T-34-76 and T-34-85 tanks to China. In 1954 the Chinese government made the decision to begin domestic production of the T-34-85 in 1958, with the new vehicle designated the Type 58. However, production was never initiated, and the Chinese army settled for modifications to the Soviet-made T-34s.
