Comparing: AC 4 Experimental vs. M4A3E8 Sherman

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.

Also known as M4А3(76)W HVSS. At the end of August 1944, a new bogie suspension was designed. The vehicle variant was mass-produced and saw battle beginning in late March 1945, with a total of 4542 vehicles of both suspension types manufactured.
