Comparing: VK 30.01 (P) vs. Type 4 Chi-To

The Porsche company developed the concept of a new vehicle in 1939. On March 5, 1941, after numerous approvals, the company prepared blueprints and, in July 1941, produced the hull from mild steel. The hull and chassis (with detachable equipment for trenching) passed performance trials. One wooden prototype of the turret and one wooden prototype of the hull were manufactured. In 1942, the project was discontinued in favor of new heavy tanks.

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.
