Comparing: Object 244 vs. T-150

A further development of the experimental tank Object 237. The Object 244 featured a more powerful gun. The fighting compartment was slightly changed: the radio was placed in a turret recess, a more efficient fan was installed, and the ammo rack and periscopic sight were modified. The driver's compartment and engine-transmission compartment were not modified. The vehicle never entered service due to problems with the gun barrel.

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.
