SMK Main Convent

The SMK was an armored vehicle prototype developed by the Soviet Union prior to the Second World War. It was named after Sergey Kirov, Sergei Mironovich Kirov, a Communist Party official assassinated in 1934. The SMK was discovered and classified by German intelligence as the T-35C, leading to the misunderstanding that the T-35 took part in the Winter War.

Only one was built and after a trial showing the downsides of its weight and size against the Kliment Voroshilov tank, KV tank and brief use in the war with Finland, the project was dropped.

Design and development

The SMK was among the designs competing to replace the unreliable and expensive T-35 tank, T-35 multi-turreted heavy tank. A design team under Josef Kotin at the Kirov Plant, Kirovski Works (formerly the Putilov Works) at Leningrad designed the tank. Competition came from the former OKMO designer N. Barykov at the Obukhov State Plant, ''Bolshevik'' Plant with their T-100 tank, T-100 tank.

In spite of the lessons that could have been learned during the Spanish Civil War, the specification drawn up for the "Anti-Tank Gun Destroyer" in 1937 required the ability to withstand 45 mm anti-tank guns at point-blank range and 75 mm artillery fire at .Zaloga p6

Meetings in 1938 resulted in a reduction in the number of turrets in the specification and changes in suspension design (going from spring-based to torsion bar). Kotin and his assistant independently designed a single-turret version of the SMK, which gained Stalin's approval and was named the Kliment Voroshilov tank, Kliment Voroshilov tank (KV). Production of two prototypes was ordered.

The SMK's armament was a short 76.2 mm gun in the upper, centrally placed turret and a 45 mm weapon in the forward turret.

Service history

The SMK, the two KV-1 (tank), KV-1 prototypes and the two T-100 tank, T-100 prototypes were put through proving trials before being tested operationally in combat at the Battle of Summa during the Winter War against Finland. The vehicles formed a company of the 91st Tank Battalion of the 20th Heavy Tank Brigade. The unit was under the command of the son of the Defence Commissar. While the SMK had thick enough armor to protect the crew from Finnish cannons and machine guns, its extremely long hull made turning difficult, especially in the dense forests where the Winter War took place. After being immobilized by a mine, the SMK had to be abandoned and was not recovered for two months.

The KV-1 and KV-2 designs proved superior in both trials in Finland and were accepted.
