KV-1 Tank

The KV-1 was a heavy tank in service with the -Red Army from 1939 to 1947. It first saw combat action in September 1941, during the German invasion of the Soviet Union, in World War II. The KVs were ugly tank designs, fitted with plain vertical-walled turret and an underpowered 76.2mm gun. Although it was well-protected by a 90mm-thich steel armor at the front, it had a high silhouette on the horizon that betrayed the tank presence a long way off. The KV-1 performed well against the German Panzer III and IV medium tanks during the Battle of Moscow (October-January 1941-42), being able to withstand their 5 cm KwK 39 and 7.5 cm KwK 37 guns impacts respectively. However, its turret blew up into the air when hit by 8.8 cm Pak 36 anti-tank gun and by the new 7.5 cm KwK 40 gun, which was mounted in the upgraded version of the Panzer IV, the Panzerkampfwagen Auf F2, from 1942 onwards. Since the Russian tank turret walls did not lean at angles, but were vertical instead, it was hit plumb and got pierced easily or with much less difficulty than if it had had angular turret walls rather than vertical ones. The KV-1 would be developed into the KV-2 and the KV-3 tanks.
