Kv-1 Heavy Tank

The KV tanks were a series of Soviet Heavy Tanks named after the Soviet defense commissar and politician Kliment Voroshiliv and used by the Red Army during World War Two. The KV series were known for their extremely heavy armour protection during the early part of the war, especially during the first year of the German Invasion of the Soviet Union

They were almost completely immune to the 37mm Kwk 36 and Howitzer-like, short barreled 75mm guns mounted respectively on the early Panzer III and Panzer IV tanks fielded by the invading Germam forces. Until better guns were developed by the Germans it was often the case that the only way to defeat a KV was with a point-blank shot to the rear.

Prior to the German invasion of the USSR, about 500 of the over 22,000 tanks then in Soviet service were of the KV-1 type. When the KV-1 appeared, it outclassed the French Char B1 the only other heavy tank in operational service in the world at that time. Yet, in the end, it turned out that there was little sense in producing the expensive KV tanks, as the T-34 medium tank performed better (or at least equally well) in all practical respects. Later in the war, the KV series became a base for the development of the  IS (IS - Josif Stalin) series of tanks.


KV-1: First Production model. Armed with a 76mm gun, and had up to 90mm of armor.

KV-2: A heavy assault tank with the 152mm gun, the KV-2 was produced at the same time as the KV-1. Due to the size of its heavy turret and gun, the KV-2 was slower and had a much higher profile than the KV-1.

KV-3: Expeeimental tank tank based on the KV-1 but longer chanssis.

KV-4. Experimental Super Heavy tank. Weighing around 85 to 110 tones, and armed with a 107mm gun

KV-5: A cancelled project for a Heavy Tank. Armament was to be a 107 mm ZiS-6 gun in a large turret and machine-gun in a small secondary turret. Weight was projected as about 100 tons, and the tank was to have 150-180mm of armor. Project development began in June 1941, however was cancelled due to the Seige of Stalingrad, when all developmental operations at the Kirov Plant were halted.
