Comparing: KV-85 vs. Object 244

A further development of the KV-1S tank. Unlike the previous modification, the KV-85 had enhanced armament. The vehicle was developed in the spring of 1943 at the Chelyabinsk Kirov Plant. The tank entered service on August 8, 1943, and was mass produced until September, with a total of 148 vehicles manufactured. The KV-85 was used by the breakthrough armored regiments of the Red Army.

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.
