Comparing: TOG II* vs. T-150

Developed for trench warfare. Initially, armament was to be placed in the front part of the hull and side sponsons. However, later it was decided not to add sponsons but to mount a turret. By 1943, when TOG 2* was completed and ready for trials, it was already obsolete. The vehicle never entered service.

The T-150 was a further development of the KV-1. The vehicle weighed as much as 50 tons. The T-150 underwent trials in the first half of 1941. A prototype fought in the battles for Leningrad, and became a basis for a modification of the KV-1 with reinforced armor.
