Comparing: KV-85 vs. ARL 44

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.

Development of the vehicle started while France was still occupied by the German forces. It was an attempt to use the obsolete B1 Bis chassis and fit it with a modern, more powerful gun. The project was finished by the Atelier de Construction de Rueil Design Bureau. A total of 60 vehicles were manufactured. However, the tank was considered unsuccessful compared to similar foreign vehicles.
