The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value.

The <value_unset_error> is a [[|]] tier .

<value_unset_error>

It is in many ways the antithesis of the IS-3 - it is slow but heavily armored, just like the KV-5, and has the same pitiful turret traverse speed. This ensures that the KV-4 is ill-suited to defend against flankers or circling tanks. While it does have 180mm of frontal armor, it is nearly unsloped and it is recommended that the hull of the tank be angled to maximize its effect and make use of the sturdy sides. The long 107mm's penetration and damage are comparable to those of German long 105mm from the Tiger II and it is relatively accurate. This allows it to work much like the Tiger II as a slow, long-range sniper with thick armor, capable of going into close-range combat if needed. This tank weighs over a 100 tons, roughly 53% of the Maus's weight and only 29 tonnes lighter than the E-100 . The weight ensures that any tanks that dare ram this tank will receive a harsh punishment.

The <value_unset_error> marks the end of its line.

Player Opinion

Pros and Cons

Pros:


  • Heavily armored, especially on the sides and turret
  • High mass makes it resistant to being rammed
  • Very strong side armour for its tier combined with thick tracks make it one of the best sidescrapers in the game
  • Unreal ability to soak up damage (even artillery shells sometimes seem to just get absorbed)
  • Long 107mm gun is pretty accurate for a Russian gun, well suited for mid-range encounters


Cons:


  • Low view range
  • Low mobility and low top speed
  • Slow turret traverse
  • Huge silhouette
  • Armor is mostly unsloped, making it especially vulnerable to gold shells.


Performance

Equipped with the 107mm gun, top engine and turret, it will become in many ways superior to the KV-5, as they both share the same amount of armor but the KV-4 lacks the weak frontal "R2-D2" radioman turret from the KV-5, and has superior penetration. Unfortunately, the KV-4's top gun has a very slow firerate and low DPM, less than 1700 damage per minute (base with 100% crew), while the KV-5 has 2100. Another problem is the long aiming time. The KV-4 also has slower top speed, making ramming less effective.

It should also be noted that the KV-4 is a fairly decent tank to play, especially if you have cover from artillery. It is very bouncy, and many shots, including those from Tier 8, and sometimes even tier 9 TD's will ricochet if tank is angled properly. Note that miniturret on top of update turret is not really a weak spot, but has the same armor as the flat turret face. It's possible to angle the turret between shots to increase its effective armor.

Coaxing out a KV-4 from a narrow defensive position will take great effort, especially on alleys or bridges, and even so, it shall be noted that the indicated side armor value does not account for the fact that shells hitting the sides will also have to go though the massive tracks, much to the dismay of the enemy. In addition to its thick side armor, the mid-mounted turret allows it to use side-scraping techniques much more effectively than the front mounted turrets used by most other tier 8 heavy tanks.


Early Research

Researching the long 107 will be top priority as the penetration of the 122mm gun is inadequate for the KV-4 as a tier 8. Once the 107 is researched and mounted, it is possible, and somewhat plausible, to simply grind on through to the ST-I. None of the other modules transfer through, and you can equip the 107mm on the stock suspension without having to purchase torsion bars. If however you feel that the extra mobility that the suspension, engines and turret traverse (2 extra degrees/s) provide are valuable follow the research guide below.

  • Research the Engine
  • Research the Suspension
  • Research the Turret
  • Research the Radio

Historical Info

The KV-4 (Object 224) was a proposed Soviet heavy break-through tank, developed during World War II. Part of the Kliment Voroshilov tank design series, it never progressed past a series of feasibility studies.

Design History

In April 1941, it was decided to create a project for a new Super-heavy tank. It was supposed to be able to defeat any German heavy tank. The project was intended to remain an unbuilt design, until it was needed. Several tank designers were told to create basic concept drawings. Sources differ as to the designers involved. Among those listed are: Kreslavsky; Kuzmin, Tarapatin and Tarotko (who together worked on the same design); Pereverzev; Mikhailov; Kruchenykh; Tseits, K. Buganov; S. Fedorenko; G. Kruchenykh; F. Marishkin; G. Moskvin; N. Strukov; A. Yermolaev; L. Sychev; L. Pereverzev; Bykov; N. Dukhov; M. Kreslavskiy; V. Pavlov; D. Grigorev. Basic armour was to be 125 to 130 mm and up to 150 mm over vulnerable areas. A new gun was required. There were about 20 different designs generated by the project. The lightest design was 82.5 tonnes and the heaviest was 107.7 tonnes. All had a 107mm ZiS-6 main gun and all but one had a second tank gun. The second gun was a 45 mm 20-K, or a 76 mm gun. Solutions to the positioning of the guns – turrets or hull mountings – varied. Crew requirements were from 5 to 9 men. The tank was never needed and by the end of the war, there were superior heavy tanks the IS-3 heavy tank already in production.

The 107 mm ZiS-6 Guns

The F-42 107 mm tank gun was created in Plant #92, in a design bureau under the supervision of V. Grabin. The F-42 was based on the F-39 95 mm tank gun and it was finished in the fall of 1940. By the beginning of 1941, the new gun had been factory tested in a field casemate. In March 1941 it was tested in the turret of a KV-2 tank. The ZiS-6 gun passed factory testing by June 1941, after which it was sent to the Artillery Scientific Test Range at Leningrad.

According to V. Grabin ("Oruzhie Pobedy" - "Weapons of Victory") about 600 ZiS-6 guns had been finished by the fall of 1941. Those guns were all destroyed because the tanks were never going to be made. The plants chief designer wrote that "five serially-produced ZiS-6 cannons were manufactured in July-August 1941, after which their production was halted because the heavy tanks were not ready". Those documents had been signed by V. Grabin.
