Comparing: A-43 vs. AC 4 Experimental

Developed at Factory No. 183 in 1941 under the designation A-43. The vehicle was to replace the T-34. The A-43 was conceived to feature a torsion bar suspension, a V-5 engine, a new transmission, a commander’s cupola, and front armor enhanced to 60 mm.

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.
