SMK (named after Sergei Mironovich Kirov - the recently assassinated party official) was an armored vehicle prototype developed by the Soviet Union prior to the Second World War. The SMK was mistakenly known to German intelligence as the T-35C.
Only one was built and after a poor showing against other designs and brief use in the war with Finland, the project was dropped.
Design and development[edit | edit source]
The SMK was among the designs competing to replace the unreliable and expensive T-35 multi-turreted heavy tank. A design team under Kotin at the Kirovski Works (formerly the Putilov Works) at Leningrad designed the tank. Competition came from the former OKMO designer N. Barykov at the Bolshevik Plant.
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 1,200 m (1,300 yd). Meetings in 1938 reduced the number of turrets in the specification and a move to torsion bar from spring suspension. Kotin and his assistant independently designed a single-turret version of the SMK which received Stalin's approval and the name 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[edit | edit source]
The SMK, the two KV-1 prototypes and the two T-100 prototypes were put through proving trials before being tested operationally in combat 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. After being immobilized by a mine, the SMK had to be abandoned and was not recovered for 2 months.
The KV design proved superior in both trials in Finland and was accepted.
