The SMK was an armored vehicle prototype developed by the Soviet Union prior to the Second World War. It was named after 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. [1]
Only one was built and after a trial showing the downsides of its weight and size against the KV tank and brief use in the war with Finland, the project was dropped.
The SMK was among the designs competing to replace the unreliable and expensive T-35 multi-turreted heavy tank. A design team under Josef 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 with their 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 1,200 m (1,300 yd). [2]
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.
The SMK, the two KV-1 prototypes and the two 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.

The IS tanks were a series of heavy tanks developed as a successor to the KV-series by the Soviet Union during World War II. The IS acronym is the anglicized initialism of Joseph Stalin. The heavy tanks were designed as a response to the capture of a German Tiger I in 1943. They were mainly designed as breakthrough tanks, firing a heavy high-explosive shell that was useful against entrenchments and bunkers. The IS-2 went into service in April 1944 and was used as a spearhead by the Red Army in the final stage of the Battle of Berlin. The IS-3 served on the Chinese-Soviet border, the Hungarian Revolution, the Prague Spring and on both sides of the Six-Day War. The series eventually culminated in the T-10 heavy tank.
The Kliment Voroshilov (KV) tanks are a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt German formations. The German Wehrmacht at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the "Russischer Koloss" – "Russian Colossus".
The T-28 was a Soviet multi-turreted medium tank. The prototype was completed in 1931, and production began in late 1932. It was an infantry support tank intended to break through fortified defences. The T-28 was designed to complement the heavier T-35, with which it shared turret designs. The type did not have great success in combat, but it played an important role as a development project for Soviet tank designers. A series of new ideas and solutions that were tried out on the T-28 were later incorporated in future models.
The T-35 was a Soviet multi-turreted heavy tank of the interwar period and early Second World War that saw limited service with the Red Army. Often called a land battleship, it was the only five-turreted heavy tank in the world to reach production, but proved to be slow and mechanically unreliable. Most of the T-35 tanks still operational at the time of Operation Barbarossa were lost due to mechanical failure rather than enemy action. It was designed to complement the contemporary T-28 medium tank; however, very few were built.
The BT tank was one of a series of Soviet light tanks produced in large numbers between 1932 and 1941. They were lightly armoured, but reasonably well-armed for their time, and had the best mobility of all contemporary tanks. The BT tanks were known by the nickname Betka from the acronym, or by its diminutive Betushka. The successor of the BT tanks was the famous T-34 medium tank, introduced in 1940, which would replace all of the Soviet fast tanks, infantry tanks, and light tanks in service.
The SU-85 was a Soviet self-propelled gun used during World War II, based on the chassis of the T-34 medium tank. Earlier Soviet self-propelled guns were meant to serve as either assault guns, such as the SU-122, or as tank destroyers; the SU-85 fell into the latter category. As with the other AFVs in the SU series, the designation "85" refers to the vehicle's main armament, the 85 mm D-5T gun.
The SU-152 is a Soviet self-propelled heavy howitzer used during World War II.
The T-50 was a light infantry tank built by the Soviet Union at the beginning of World War II. The design for this vehicle had some advanced features, but was complicated and expensive, and only a short production run of 69 tanks was completed.
The T-60 scout tank was a light tank produced by the Soviet Union from 1941 to 1942. During this period, 6,292 units were built. The tank was designed to replace the obsolete T-38 amphibious scout tank and saw action during World War II.
The BA-3 was a heavy armored car developed in the Soviet Union in 1933, followed by a slightly changed model BA-6 in 1936. Both were based mostly on BA-I, the most important development being the new turret, same as in the T-26 m 1933 and BT-5 tanks, and also equipped with the 45 mm main gun.
The 76 mm tank gun M1940 F-34 was a 76.2 mm Soviet tank gun used on the T-34/76 tank. A modified version of the gun, the 76 mm tank gun M1941 ZiS-5, was used on KV-1 tanks during World War II. Nowadays, the two versions are often referred to just by their factory designations, as "F-34" and "ZiS-5", respectively.
Tanks were an important weapons system in World War II. Although tanks in the inter-war years were the subject of widespread research, few were made, in just a few countries. However, during World War II, most armies employed tanks, and thousands were built every month. Tank usage, doctrine, and production varied widely among the combatant nations. By war's end, a consensus was forming on tank doctrine and design.
The T-18 light tank was the first Soviet-designed tank. Produced from 1928 to 1931, it was based on the Renault FT, with the addition of a vertically sprung suspension.
The T-43 medium tank was a prototype Soviet medium tank developed during the Second World War as a possible replacement for both the T-34 medium and KV-1 heavy tanks. The project's aim was to build a medium tank with heavier armour, but German advances in tank technology proved better countered by a more heavily armed T-34-85 and the T-43 was cancelled.
The SU-100Y, initially designated T-100Y, was a Soviet prototype self-propelled gun, developed from the chassis of the prototype T-100 tank. It was developed during the Winter War with Finland to include a 130 mm gun to destroy concrete defensive structures like bunkers and anti-tank obstacles along with the use as a tank destroyer. It did not see serial production.
OKMO was the tank design team in the Soviet Union during the early 1930s. Located in Leningrad, it produced the design of the T-26 infantry tank, of which about 12,000 would be produced. Most other designs from the bureau never saw the light of day, but it was here that Mikhail Koshkin, designer of the famous T-34 medium tank gained his early experience. The bureau was gutted in the Great Purge and broken up by the beginning of the Second World War.
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 were 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.
