KV-85 Heavy Tank
Designed with a larger turret to accommodate the 85 mm multipurpose gun, a new cupola, and a ball mounted MG in the turret rear.
It started appearing at the front in the summer of 1943 and was available in large numbers at Kursk in July 1943.
Another source says they didn't first appear until December 1943 against Army Group North. The 27th Guard Regiment had 20 tanks in 4 companies and were decimated by the German defenses.
Some KV-1Cs were upgraded in the winter of 1943-44. At the start of 1944 all production ceased in favor of the IS series.
