Comparing: Type 4 Chi-To vs. AC 4 Experimental

The Type 4 Chi-To medium tank was developed in 1943 on the basis of the Chi-Nu. The tank was conceived to replace the Chi-Ha. However, mass production was not launched due to shortages of materials and components. A total of six chassis were produced, and only two tanks were built on their basis.

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.
