The KV-1S is a Soviet tier 6 heavy tank.

A lighter and upgraded version of the KV-1, with a total of 1,370 the KV-1S bis vehicles and 148 KV-85 vehicles manufactured.

Being the only way to access the IS from the heavy line since the 0.7.3 patch, this tank has become a more common sight in battles. To most players, the KV-1S is considered the best Tier 6 tank presently available in the game. It is the antithesis to its counterpart, the T-150, as this tank trades in its armor for excellent mobility. This tank can lead an assault and it can either be immediately behind the heavier tanks or try to flank the enemy and hit hard with the powerful D-2-5T. Just watch out for the reload time. The KV-1S is also very popular in tank companies along with the M18 Hellcat. Despite only having 75mm of frontal armor, the KV-1S is a hard nut to crack, keep in mind though that most shots planted behind the turret will result in a fire. A fire extinguisher is highly recommended for this tank, as well as a medic kit.

The KV-1S leads to the KV-13, the IS and the MT-25.

Historical Info

According to one of the KV-1's designers: "During 1942 we were still in need of a reliable heavy tank. That's why we were defeated in Crimea and at Kharkov. The KV-1 completely discredited the concept of a heavy tank".

Some Red Army high commanders demanded that all production of heavy tanks be stopped. Others suggested development of an "universal tank", something between heavy and medium tank. By the way, in the 1960's-1970's tank designers around the world came to the conclusion that it was the right decision.

Soviet tank builders tried to develop such a tank. This tank was named the KV-13. It contained many brilliant ideas (some of those ideas were applied in the IS-2 tank), however it never served in the Red Army.

At this time, a new decision was made to fully re-design KV-1. Soviet tank designers wanted to develop a new KV with lighter armor and higher speed and maneuverability like T-34 Medium Tank. The new tank was named KV-1S where "s" letter means "skorostnoy" or "speed". The KV-1S was lighter than its predecessor by up to 5 tons. The thickness of the frontal armor was lowered from 90 mm to 75 mm. The rear hull was re-designed. The existing road wheels were replaced with newer, lighter ones. The KV-1's transmission was re-designed as well.

The old gear-box was replaced with a new one and the tank received a new turret with a commander's cupola (the first Soviet tank with a commander's cupola was T-50 Light Tank). Both ZIS-5 or F-34 tank guns could be mounted in this turret. In addition, the new tank was armed with four machine-guns: a coaxial MG, a bow MG, an AA machine-gun, and a MG in the rear of the turret. Also, new tracks (608 mm width) were designed specially for this tank.

In the summer of 1942, the KV-1S prototype was tested. On August 20, 1942, the production of this tank had begun. However, when the KV-1S appeared in the war theatre, the Red Army was already in need of a tank with thicker armor and better protection. A total of 1370 KV-1S were built. In April 1942 its production was cancelled. Many tanks were sent in tank brigades because the reorganization of the Red Army had not begun yet. The KV-1S took part in all major operations of the Red Army including Siege of Berlin.
