The KV-1S is a Soviet tier 6 heavy tank.
A further modification of the KV-1 heavy tank series developed in the summer of 1942. It passed into Red Army service on August 20, 1942. Compared to its predecessors, KV-1S had several design features which allowed for the tank’s weight to be reduced to 42.3 tons. Also, the KV-1S had increased top speed, maneuverability, and durability. However, the 76-mm ZIS-5 gun remained. This, coupled with reduced and inefficient armoring, made the new vehicle basically equal to the T-34 in terms of battle performance. A total of 1,083 vehicles of this modification were manufactured. This tank was widely used on all fronts of the Great Patriotic War.
The KV-1S has an interesting history in World of Tanks. Starting as the only way to access the IS from the heavy line in 0.7.3, it was then moved down to Tier V and replaced by the KV-85 in 0.9.3, only to once again take its place as one of the Tier VI Soviet heavy tanks in update 1.9, though now without access to the 122mm gun that once made it infamous. This tank trades in some of the KV-1's armor for improved mobility, allowing it to spearhead assaults and deal quite a bit of damage with either of its top guns.
The KV-1S leads to the IS.

Player Opinion
Pros and Cons
Pros:
- One of the most mobile of the Tier VI heavies
- Choice of two guns: a fast-firing 85mm for medium to long range engagements, or a fearsome but inaccurate 122mm howitzer
- Best DPM of all Tier VI heavies with the 85mm
- Excellent at the "peek-a-boom" tactic
Cons:
- Somewhat poor view range for its tier
- Joint weakest armor of the Tier VI heavies
- Catches fire easily due to fuel tanks along most of the sides of the tank
- Mediocre penetration and very poor gun depression (buffed from 3.5 to 5 as of 1.9.1)
- Bad stock grind
Performance
This tank can be quite tricky to play for those who come straight from the KV-1 as it uses a completely different play style from its predecessor. It makes a good front line tank, as its speed and maneuverability allow it to move to where its gun is most needed. If you support a medium flank you can use the mediums as a distraction to take on the targets they cannot reliably defeat, or give them the added firepower they need to break through. Learn what you can outmaneuver and what you can engage head on. When in the right hands this tank easily makes up for its shortcomings and offers invaluable practice in learning to drive and operate the IS tank series.
But be aware that this tank is not meant to fight at long range. Its long aim time, bad accuracy, and long reload will have you pulling hair out if you try to take on German tanks at range. However, don't be afraid to scope in and shoot if you have a clear, safe shot. Although still unreliable at best, the long range combat is more viable as of Update 1.9.1 buffing the KV-1S.
With a one-for-each-position crew setup -- Commander/Gunner/Driver/Radio Operator/Loader -- the KV-1S is crew-compatible with four Soviet premiums: the Churchill III, KV-1 Shielded, KV-220-2, and the newer KV-1SA; your KV-1S crew can be used in all four without penalty.
Overall, stick to your strengths -- close range, urban combat fighting and you will come out victorious. But if you see a full HP Tier IV in the sights, don't be afraid to show them one big reason why that is often considered the worst tier in the game.
- NOTE: As of Update 1.9.1 the KV-1S received buffs. On all guns apart from the stock gun, the bloom after firing has been decreased by 20%, letting long range combat be a fair amount more viable. The dispersion on the 122mm howitzer has been decreased from 0.50 to 0.46, the turret rotates roughly 3 degrees per second faster, and the gun depression on all of the guns has been increased from 3.5 to 5 degrees.
Early Research
- The 10RK radio transfers over from the KV-1 and should be installed immediately.
- Prioritize the 85 mm S-31M for a much needed gun upgrade.
- Then, research the V-2IS engine for a nice boost to mobility.
- Research the KV-122 mod. 1944 turret for a slight boost to view range and HP.
- Research either the 122 mm Howitzer S-41 for a different playstyle or the KV-1S mod. 1943 suspension for a slight boost to mobility.
- Research whichever module you didn't choose previously.

Historical Info
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.

Historical Accuracy Errata
Has the same ZiS-5 gun as the KV-220-2. However, their penetration values are inconsistent.
