The T-100 was a Soviet twin-turreted heavy tank prototype, designed in 1938–39 as a possible replacement for the T-35 heavy tank. The T-100 was designed by N. Barykov's OKMO design team at S.M. Kirov Factory No. 185 in Leningrad. The T-100 was originally conceived with three turrets and was eventually built with two. It was in competition with a similar design, the SMK, but neither was adopted and instead a single turret version of the SMK was ordered as the KV-1. All three prototypes were tested at the same time in the Battle of Summa during the Winter War with Finland.
