The KV-1, mass-produced from Feb 1940 to early 1943. It first saw service in the Finnish winter war, and when Germany attacked Soviet in June 1941, some 636 KV (Kliment Woroshilov) tanks had been built. The KV-I was armed with a 76.2mm L/30.5 gun, but later variants (KV-1A, KV-1B, KV-1C and KV-1S) housed a 76.2mm L/41 gun with better armour penetration. The KV-1E later appeared with additional armour plates. Also a KV-2 was produced. It's main task was to support infantry and was armed with a 152mm cannon. But since the KV-2 had bad performance it was only produced until 1942. Plans were also made to construct a KV-4, KV-5 and a KV-13, but all projects were abandoned.
