To counter that threat, Soviet factories churned out 148 KV-85s, a stopgap model upgraded with an eighty-five-millimeter gun. However, tank designers were already working on installing the gun on the T-34 tank, while the more heavily armed and armored Joseph Stalin series of tanks took over the KV’s role. Still, small numbers of surviving KV-1s would serve through the remainder of the war, including in the siege of Leningrad, the recapture of Crimea and the invasion of Japanese-held Manchuria in August 1945.
Despite their superior armor, the KV tanks simply sacrificed too much mobility, reliability and cost-efficiency to equal the success of the T-34. However, that doesn’t change the fact that the formidable tanks and their crews served as a vital bulwark in the desperate early months of the Nazi invasion.
