History of Tank: 

The Kliment Voroshilov (KV) tanks are a series of Soviet heavy tanks named after Soviet defense commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. KV tanks were known for their heavy armor during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In some situations, even a single KV-1 or KV-2 supported by infantry could stop German formations. The German Wehrmacht at that time rarely deployed its tanks against KVs, as their armament was too meager to deal with the “Russischer Koloss” – “Russian Colossus”.

The KV tanks were virtually immune to the 3.7 cm KwK 36 guns and the howitzer-like short-barreled 7.5 cm KwK 37 guns mounted, respectively, on the first Panzer III and Panzer IV tanks fielded by the forces of German invasion. Until the Germans developed more effective weapons, the KV-1 was invulnerable to almost all German weapons except the 8.8 cm Flak gun.

Before the start of Operation Barbarossa in June 1941, approximately 500 of the more than 22,000 tanks then in Soviet service were of the KV-1 type. As the war progressed, it became apparent that there was little point in producing the expensive KV tanks, as the T-34 medium tank performed better (or at least as good) in all practical respects. In fact, the only advantage the KV had over the T-34/76 was its larger and more spacious three-man turret.[9] In the course of the war, the KV series became the basis for the development of the IS (Iosif Stalin) series of tanks and self-propelled guns.

History of development

After disappointing results with the multi-turreted T-35 heavy tank, Soviet tank designers began designing replacements. The T-35 conformed to the 1920s concept of a “revolutionary tank” with very high firepower, although its armor was lacking and it suffered from poor mobility. The Spanish Civil War demonstrated the need for much heavier armor on tanks,[citation needed] and was the major influence on Soviet tank design just prior to World War II.

Several competing designs were offered and even more were worked on before reaching the prototype stage. All had heavy armor, torsion bar suspension, wide tracks and were of welded and cast construction. One of the main competing designs was the SMK, which in its final form had two turrets, mounting a 76.2 mm and a 45 mm gun. SMK designers independently developed a single turret variant which received approval at the highest level. Two of these, named after the People’s Commissar of Defense, were ordered together with a single SMK. The smaller hull and single turret allowed the designer to install heavy frontal and turret armor while keeping weight within manageable limits.

The KV was ordered straight from the drawing board. When the Soviets entered the Winter War, the SMK, KV, and a third model, the T-100, were sent to be tested in combat conditions. The KV outperformed the SMK and T-100 models. The KV’s heavy armor proved highly resistant to Finnish anti-tank weapons, making it more difficult to stop. In 1939, production of 50 KV was ordered. During the war the Soviets found it difficult to manage the concrete bunkers used by the Finns and a tank with a large howitzer was required. One of the most urgent projects to meet the demand was to place the howitzer in a new turret on one of the KV tanks.[11] Initially known as ‘Malen’kaya Bashenka’ (small turret) and ‘Bol’shaya Bashnya’ (large turret), the tank with the 76 mm armament was renamed the KV-1 heavy tank and the one with the 152 mm howitzer as KV- 2 Heavy artillery tanks.

KV tanks first faced the Germans in the Battle of Raseiniai, soon after the start of Operation Barbarossa. On June 23, over 200 German tanks advancing through Lithuania encountered Soviet armor, including KV-1 and KV-2 tanks. Although their frontal armor was sufficient to deflect anti-tank fire, German troops were able to outflank them and destroy them with explosive charges or lure them into close range by direct-fire artillery. Of the more than 200 Soviet tanks lost at Raseiniai, 29 were KVs.

The KV’s strengths included armor that was impenetrable by any tank-mounted weapon then in service except at close range, that it had good firepower, and that it had good buoyancy in soft ground. It also had serious flaws: it was difficult to steer; the transmission (which was a twenty-year-old Holt Caterpillar design) “was the KV-1’s main handicap, and there was some truth in the rumors that Soviet drivers had to change gears with a hand sled”; and ergonomics were poor, with limited visibility. Furthermore, at 45 tons, it was simply too heavy. This severely affected maneuverability, not so much in terms of top speed, but due to the inability to cross many bridges that medium tanks could cross. The KV outperformed most other tanks of the time, being about twice the heaviest German tank of the time (before the Tiger). Because applied armor and other improvements were added without increasing engine power, later models were less capable of keeping up with medium tanks and had more problems in difficult terrain. Furthermore, its firepower was no better than that of the T-34. It took field reports from senior commanders “and certified heroes”, who could be honest without risk of punishment, to reveal “what a dog the KV-1 really was”.
