Description

The KV-2 (ZiS-6) is a gift rank III Russian heavy tank with a battle rating of 5.0 (AB/RB/SB). It was introduced in Update 1.59 "Flaming Arrows" as a premium pack but was removed from the store at the end of the 2018 6th Anniversary sale. It was shortly available from the store during the 2019 "Black Friday". It was also made available in-game for golden eagles (Ge icon.png) during the 2019 "Tankers' Day" and the 2021 "Defender of the Fatherland" mini-events.

The KV-2 (ZiS-6) is a heavy artillery tank. It is an experimental up-gunned variant of the KV-1 and KV-2 models built with an emphasis of destroying fortification, bunkers and enemy armoured vehicles, featuring the new 107 mm ZIS-6 cannon. Although the armour thickness is the same as the KV-1 and KV-2, this vehicle is notable for having a more powerful cannon; although smaller in calibre to the KV-2, has much higher armour penetration values. In fact, the tank fires Armour-Piercing High-Explosive (APHE) shells with the highest penetration value out of all USSR tanks both at and below its battle rating. With about 163 mm of penetration in normal combat conditions and with 440 grams of explosive filling carried by the default B-420 shell, this tank will obliterate all enemy vehicles upon penetration with the exception of some light-armoured vehicles of which the contact fuse may fail to detonate. Despite its significantly powerful armament, the KV-2 (ZiS-6) is plagued by inherited weaknesses shared within the KV lineage of tanks. At its battle rating, the tank's armour will be of little protection against other hostile vehicles it will face. With just 75 mm armour all around and including the largely slat and exposed turret, almost all tanks and the ammunition they fire (a significant number of which have double the penetration value of the thickness of the KV's armour) will penetrate with little to no difficulty. Tightly packed and strewn ammunition both within and at the base of the turret will more than likely turn the entire vehicle into a erupting volcano upon being struck by stray shells, if not outright cripple the crew to the point the fire-rate is reduced to virtually a standstill. This tank is a spiritual successor of the original KV-2 in combat operations. Although a high crew count of 6, the rate of fire is relatively slow but faster than its predecessor with a higher velocity and flatter trajectory. The same is unfortunately to be said for its slower turret traverse, reverse and acceleration speed and heavy weight.

Operational and visual characteristics of the KV-2 (ZiS-6) retain the visual and operational similarities to the KV-2 which it is upgraded from. Players experienced in operating previous models of the KV-2 or Soviet SPGs should have little to no difficulty in adjusting to this vehicle. The ZiS-6 can be distinguished from its KV and KV-2 predecessors by its enlarged and tall rectangular turret and longer barrel. A quick glance at this vehicle may be mistaken for similar looking tanks such as the KV-2 in which shares the same turret shape.

The KV-2 (ZiS-6)'s closest and most popular competitor of the same battle-rating is the KV-85. The KV-85 when compared, is free to unlock with currency spending, is lighter in weight, more manoeuvrable, faster in fire rate and turret traverse at the expense of fewer crew members. What the ZiS-6 lacks in these qualities may be compensated by its firepower comparable to 'a mini IS-2' as well as the added Premium talisman RP and SL increase bonus of which the KV-85 will lack on the get-go. These detail and information should be considered by the interested user when deciding whether to purchase this tank and incorporating it into their existing arsenal, or when taking into battle. The KV-2 (ZiS-6) will reward those who are patient, and a boon to those seeking increased premium firepower unmatched by any other USSR vehicle at its rank.

The armour protection of the KV-2 (ZiS-6) is really not great at its BR. The hull front and sides largely consist of 75 mm thick armour plates, which allow the player to angle the hull and increase its effective thickness to ~90-110 mm. However this is still penetrable by common opponents, such as Tiger H1, M4A2 (76) W, Chi-Nu, etc. The biggest and most noticeable weakspot of this KV-2 is of course the huge and flat turret. Protected by 75 mm unsloped armour all round, the turret usually fails to resist incoming shells regardless of whether the player angles it or not. While the original KV-2 has a large bulge on the gun mantlet that can bounce/absorb shells, the KV-2 (ZiS-6) does not. The huge gun mantlet only has the gun barrel sticking out, making it even easier to penetrate. The only advantage brought by this all-round protection is probably that the KV-2 is immune to almost all SPAA (eg. Wirbelwind, M19) or, when angling, low tier tanks. Opponents who deliberately bring low tier tanks (eg. M22, Ho-Ro) into this BR will have a hard time trying to penetrate a KV-2 (ZiS-6). The roof armour is between 30-35 mm which can effectively block .50 cal AP bullets, commonly used by Allied planes like P-47D and P-51. However, some aircraft have the ability to penetrate this 30 mm of armour even from far away, for example the Do 335 B-2 whose MK 103 penetrate ~60 mm at ~600 m.

Thanks to the spacious interior and an abundance of crew (6), the KV-2 (ZiS-6) can usually survive a few penetrations in the turret or even in the hull. However as soon as spare crews run out, the KV-2 will once again be very vulnerable.

Usage in battles

At its Rank and Battle Rating, the KV-2 (ZiS-6)'s armour is no longer up to par against newer and more powerful weapon systems of opposition vehicles it will face. Although unlike the IS-1 successor of which is unable to protect itself by angling due to the rounded turret mount causing a vulnerability, the KV-2 has less of this issue as the entire front potion of the front and lower-plate is designed to be straight and rectangular and allowing it to deflect or ricochet some shots when angled optimally but the large turret is extreme exposed and vulnerable to head-on fire.

Due to its unsatisfactory manoeuvrability, fire-rate and traverse speed, close-quarters engagements against multiple enemies in small-spaced environments are highly discouraged unless absolutely necessary. The tank is too large and slow to escape or retreat from what would be overwhelming situations, and too large to hide. Should the need to enter tight alleyways and streets if towns or cities, escort either by or with other friendly units are of utmost importance and should best serve in a support capacity should more heavily armoured opponents are encountered. This tank excels best at long to medium range engagements on largely open areas. Due to its poor -5 degrees of gun depression - a trait inherited by all USSR armoured vehicles, engaging hostiles by cresting over the tops of hills are highly discouraged unless absolutely necessary. Should clusters of multiple hostile vehicles are encountered in combat, the optimal tactic is to wait for them to split up before engaging them one-by-one if the opportunity presents itself.

Lightly armoured vehicles where the contact fuse may not activate upon penetration such as the Waffentrager or Nashorn are of the most concern as the default B-420 APHE shell has the tendency of penetrating from the front to rear dealing less damage than what is expected. Follow up shots may be required. Although the HE OF-420 shell is an excellent solution, the 16 .7 to 21.51 seconds of shell swap may not warrant enough justification for use when few seconds are only available to determines survival.

Another class of vehicles of significant threat are fast-tanks such as the M18 GMC or T-34 tanks capable of running circles in ways the KV-2 (ZiS-6)'s slow turret traverse rate and poor manoeuvrability will be unable to cope in close-quarters engagements. The last type of vehicle of concern are low-chassis tanks such as the ASU-57, ASU-85, PT-76B and even some German tank-destroyers are so small to the point they safely drive up to the vicinity of KV-2 and be immune from retaliation due to the 107 mm gun situated on a high turret and only -5° degrees of elevation down and 15° up

Pros and cons

Pros:

  • Excellent firepower
  • Greatly improved reload speed over previous KV-2 models
  • High crew capacity (6)
  • High velocity and powerful munition
  • Premium talisman with RP and SL increase bonus

Cons:

  • Slow rate of fire
  • Insufficient armour protection
  • Poor gun depression of -5° (common trait of all USSR tanks)
  • Large profile
  • Poor manoeuvrability and slow speed
  • High weight
  • High risk of internal ammunition explosions by penetrating shells

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
