Soviet T-100Z Heavy Tank. TRUMPETER 09591

The T-100 was a Soviet twin-turreted heavy tank prototype, designed in 1938–39 as a possible replacement for the T-35. 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 were adopted, and instead a single-turret version based on the SMK was ordered as the KV-1. All three prototypes were tested at the same time in the Battle of Summa.

The T-100 tank had two turrets arranged longitudinally, requiring a long chassis. The front turret, mounting a 45 mm anti-tank gun, had a limited field of fire due to the second turret behind it. The second turret, mounting a 76.2 mm gun, was set higher on top of the superstructure than the first and was thus able to traverse a full 360 degrees.
