Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. 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. These differences are taken into account in tooltip boxes.

AnnoR80_KV1.png

390000

The KV-1 is a Soviet tier 5 heavy tank.

Development started at the end of 1938. A prototype was produced in August 1939. The vehicle first saw combat in December 1939 at the Mannerheim Line. The tank was mass-produced from March 1940 through August 1942, with a total of 2,769 vehicles manufactured.

Most novice players will find the KV-1's playing style significantly different from what they are used to, having just come out of the T-28 medium tank. At stock, armed with the adequate 76mm ZiS-5, it is very slow, and certainly not agile. Consider mounting the 57mm 413 if you enjoy a fast fire rate with decent penetration. The KV-1 with the 122mm U-11 gun firing HE shells can be a surprisingly fun tank to play, but don't expect to be doing much when you get thrown in with the big boys battles.

It's one of the tanks new players should definitely learn to kill as the same weak spots are shared with other tanks in the KV family. Frontal weak-spots include the flat plate directly below the turret and the lower plate below the heavily sloped mid section, and shots to the side and rear will penetrate the flat 60mm armoring fairly consistently.

This tank used to be combined with the KV-2 in the removed KV tank.

The KV-1 leads to the T-150, the KV-2, and the KV-1S.

Player Opinion

Pros and Cons

Pros:


  • Can choose between three good guns that offer completely different styles of play with good DPM and RoF for each.
  • Excellent armor for its tier on the front and on the sides; with 110mm thick nearly impenetrable rounded upgrade turret.
  • Good at sidescraping, but mediocre reverse angling due to engine. Upper front glacis is very bouncy if the enemy doesn't aim.
  • 122mm U-11 howitzer relatively consistent penetration on low tiers and can one-shot, still capable against higher tiers.
  • 85mm has excellent fire rate, penetration, and damage, especially for its tier.


Cons:


  • Slow acceleration, and otherwise poor maneuverability: often an easy priority target for SPGs.
  • Top speed and strategic mobility is acceptable but lower than IS-line.
  • Really bad view range (gets sniped easily by invisible tanks outside of range)
  • Slow aiming time on large guns; especially 122mm howitzer, with low accuracy and long reload time to boot.
  • Frontal weakspots.


Performance

The KV-1 is one of the most popular tanks in the game. Its thick armor, generous gun selection, and easy-to-learn play style make it one of the best starter tanks and allow it to easily dominate in the hands of a skilled player. In real life, the KV-1 was designed to spearhead assaults against heavily defended areas. It was nearly invulnerable to enemy guns during its time and retains this feature in World of Tanks. The KV-1 has very thick all-around hull armor and a very tough turret. This allows it to sidescrape with ease and withstand serious beatings. Although thick, the KV-1's armor is mostly unsloped which means the hull must be properly angled to realize its full potential. The KV-1 also offers a generous selection of guns: a rapid-firing and highly accurate 57mm; an extremely powerful but relatively unreliable 122mm howitzer, or a hard-hitting 85mm which mediates between the two. The only downside to the KV-1's guns are their slow aiming speeds; shells will be reloaded before the gun is fully aimed. Furthermore, the KV-1 is very slow and turns sluggishly. Its once-formidable armor and weaponry are much less effective against higher tier tanks. This coupled with poor maneuverability and speed make the KV-1 easy prey against Tier VIs and VIIs. However, don't let that dissuade you. The KV-1 is very fun and easily dominates when in a Tier V battle.

The KV-1 has excellent guns and armor for its tier which allow it to heavily dominate tanks at and below its tier. It's tough, fun, powerful, easy-to-learn, and a great choice as a starter heavy tank. The KV-1 is a keeper for many, and with good reason.

Vulnerabilities Many players at and below tier V consider the KV-1 an impenetrable wall, and rightfully so - many blind shots will bounce harmlessly off of a KV-1, making it seem pointless to keep fighting such a powerful foe. However, with just a little more aim, one can make the KV-1's armor just a bit easier to deal with. For starters, one should never shoot at the turret of a KV-1. All of it's armor is in the triple-digits, and the gun mantlet covers two thirds of the front turret, providing spaced armor atop of the already strong turret. The sides and rear of the turret are more manageable, but penetrating these parts can only be reliably done with guns of over 110 mm of penetration. However, the hull is much more juicy. On paper, the tank seems formidable, as both its front and side armor are set at 75 mm, meaning a KV-1 putting itself at a 45 degree angle to you would seem to have made itself an iron wall. No fear though - there is a machine gun port sticking out of the front of the KV-1, and by shooting at it, you completely negate any angling done by the KV-1. If the KV-1 angles its front further to conceal the machine gun port, just shoot at the side. If the KV-1 is facing you without any angle whatsoever, just shoot at the flat area right below the turret which should be facing you without any angle. If you can, also try shooting at the driver's view port, giving you a chance to hamper the already-clumsy KV-1's mobility. If you have low penetration, try shooting the upper glacis. It only has a mere 40 mm of armor, but it's steep angle will mean that it can bounce many shots unless overmatched. When shooting at the side, try to avoid hitting the tracks, as they serve as extra armor. If shooting at the back with a low penetration gun, aim for the top of the rear side, where the back bulges out, as that only has 50 mm of armor, compared to the 70 mm of the lower rear.


Early Research

  • Oddly, the M-17F engine carries over from the T-28, even though they're completely different vehicles. Install it immediately.
  • The stock suspension can't handle the weight of the second turret, so your choice to start with is between the suspension and the 57mm 413 gun. The added maneuverability from upgrading the suspension will also make the tank more comfortable to play with, while the 57mm is an excellent choice for fire support if the 122 mm is too close-ranged for your play style.
  • Whatever you choose to research from the line above, once you research the suspension, you can then research the 122mm howitzer or proceed to the second turret, making the 85mm F-30 gun available.
  • Be sure to research the 10RK radio before moving on.
  • You'll have to research the V-2K engine if you want to get the KV-1S and it can also be used on the KV-2. It is however not necessary for the T-150.

Historical Info

KV1 model 1940 s ekranami (with appliqué), or KV1-E. The slogan on the turret side reads "Victory will be ours."
The Kliment Voroshilov (KV) tanks were a series of Soviet Heavy tanks, named after the Soviet defense commissar and politician Kliment Voroshilov. The KV series were known for their extremely-heavy armor protection during the early war, especially during the first year of the invasion of the Soviet Union in World War II. Almost completely immune to the 7.5 cm KwK 37 and 3.7 cm KwK 36 guns mounted on the early Panzer III and Panzer IV tanks, until better guns were developed, often the only way to defeat a KV was a point-blank shot to the rear. Prior to the invasion, about 500 of the over 22,000 tanks in Soviet service at the time were of the KV-1 type. When the KV-1 appeared, it outclassed the French Char B1, the only Heavy tank used in the world at that time. Yet, in the end, it turned out that there was little sense in producing the expensive KV tanks, as the T-34 medium tank performed better (or at least equally) in all practical respects. Later in the war, the KV series have become a base of development of the excellent Iosif Stalin tank.

Development

After disappointing results with the multi-turreted T-35 Heavy tank, Soviet tank designers started drawing up replacements. The T-35 conformed to the 1920s notion of a 'breakthrough tank' with very-heavy firepower and armor protection, but poor mobility. The Spanish Civil War demonstrated the need for much-heavier armor on tanks, and was the main influence on Soviet tank design just prior to World War II. Several competing designs were offered, and even more were drawn up prior to reaching prototype stage. All had heavy armor, torsion-bar suspension, wide tracks, and were of welded and cast construction. One of the main competing designs was the SMK, which lowered the number of turrets from the T-35's five to two, mounting the same combination of 76.2 mm and 45 mm weapons. When two prototypes were ordered though, it was decided to create one with only a single turret, but more armor. This new single-turret tank was the KV. The smaller hull and single turret enabled the designer to install heavy frontal and turret armor while keeping the weight within manageable limits.
KV-1 On trials

When the Soviets entered the Winter War, the SMK, KV, and a third design, the T-100, were sent to be tested in combat conditions. The heavy armor of the KV proved highly-resistant to Finnish anti-tank weapons, making it more effective than the other designs. It was soon put into production, both as the original 76-mm-armed KV-1 Heavy Tank and the 152 mm howitzer-mounting assault gun, the KV-2 Heavy Artillery Tank. The KV's strengths included armor that was impenetrable by any tank-mounted weapon then in service except at point-blank range, good firepower, and good traction on soft ground. It also had serious flaws: it was difficult to steer, the transmission was unreliable, and the ergonomics were poor, with limited visibility and no turret basket. Furthermore, the 45-ton KV was simply too heavy. This severely impacted the maneuverability, not so much in terms of maximum speed, but in its inability to cross many bridges that medium tanks could cross. The KV outweighed most other tanks of the era, being about twice as heavy as the heaviest contemporary German tank. KVs were never equipped with a snorkeling system to ford rivers on the bottom, so they had to be left to travel to an adequate bridge. As applique armor and other improvements were added without increasing engine power, and later models were less capable of keeping up to speed with medium tanks and had more trouble with difficult terrain.

KV-1 Heavy tank trials on crossing antitank and natural obstacles. Reserve Front 43rd Army 109th Tank Division Sep. 1941. The sign on the turret translates as "Kill the fascist"

By 1942, when the Germans were fielding large numbers of long-barrelled 50 mm and 75 mm guns, the KV's armor was no longer invincible. The KV-1's side, top, and turret armor could also be penetrated by the high-velocity MK 101 carried by German ground attack aircraft such as the Henschel Hs 129, requiring the installation of additional field-expedient appliqué armor. The KV-1's 76.2 mm gun also came in for criticism. While adequate against all German tanks, it was the same gun as carried by smaller, faster, and cheaper T-34 medium tanks. In 1943, it was determined that this gun could not penetrate the frontal armor of the new Tiger, the first German Heavy tank, fortunately captured near Leningrad. The KV-1 was also much more difficult to manufacture and thus, more expensive than the T-34. In short, its advantages no longer outweighed its drawbacks. Nonetheless, because of its initial superior performance, the KV-1 was chosen as one of the few tanks to continue being built following the Soviet reorganization of tank production. Due to the new standardization, it shared the similar engine (the KV used a 600 hp V-2K modification of the T-34's V-2 diesel engine) and gun (the KV had a ZiS-5 main gun, while the T-34 had a similar F-34 main gun) as the T-34, was built in large quantities, and received frequent upgrades. When production shifted to the Ural Mountains 'Tankograd' complex, the KV-2 was dropped. While impressive on paper, it had been designed as a slow-moving bunker-buster. It was less useful in the highly-mobile, fluid warfare that developed in World War II. The turret was so heavy it was difficult to traverse on non-level terrain, and it was expensive to produce. Only about 250 KV-2s were made, all in 1940-41, making it one of the rarer Soviet tanks. As the war continued, the KV-1 continued to get more armor to compensate for the increasing effectiveness of German weapons. This culminated in the KV-1 model 1942 (German designation KV-1C), which had very heavy armor, but lacked a corresponding improvement to the engine. Tankers complained that although they were well-protected, their mobility was poor and they had no firepower advantage over the T-34 medium tank. In response to criticisms, the lighter KV-1S (Russian language: КВ-1С) was released, with thinner armor and a smaller, lower turret in order to reclaim some speed. Importantly, the KV-1S also had a commander's cupola with all-around vision blocks, a first for a Soviet Heavy tank. However, the thinning-out of the armor called into question why the tank was being produced at all, when the T-34 could seemingly do everything the KV could do and much more cheaply. The Soviet Heavy tank program was close to cancellation in mid-1943. The appearance of the German Panther tank in the summer of 1943 convinced the Red Army to make a serious upgrade of its tank force for the first time since 1941. Soviet tanks needed bigger guns to take on the growing numbers of Panthers and the few Tigers. A stopgap upgrade to the KV series was the short-lived KV-85 or Objekt 239. This was a KV-1S with a new turret designed for the IS-85, mounting the same 85 mm D-5T gun as the SU-85 and early versions of the T-34-85. Already-high demand for the gun slowed production of the KV-85 tremendously, and only 148 were built before the KV design was replaced. The KV-85 was produced in the fall and winter of 1943-44; they were sent to the front as of September 1943, and production of the KV-85 was stopped by the spring of 1944 once the IS-2 entered full scale production.

Combat History

Raseiniai

German officers are examining the damaged Soviet KV-1 Heavy tank screened with additional armor. It probably belonged to the 101st Tank Division.

When Operation Barbarossa began, the Red Army was equipped with 508 new KV tanks. Its armor was so effective that the Germans were incapable of destroying it with their tanks or anti-tank weapons, and had to rely on air support and 88 mm anti-aircraft artillery (flak) or 105 mm howitzers to knock them out. Most of these tanks, and the effective T-34s, were parcelled out to units in small numbers and poorly supplied, but at the Battle of Raseiniai they were used to good effect. On 23–24 June, a single KV-2 effectively pinned down elements of the German 6th Panzer Division for a full day at the bridgeheads of the Dubysa River below Raseiniai, Lithuania, playing a prominent role in delaying the advance of Panzergruppe 4 on Leningrad until it ran out of ammunition and the crew was forced to abandon the tank and withdraw. According to Panzer Operations, however, the tank (said to be a KV-1), after destroying several antitank guns, their crews, and an 88 mm flak gun, was hit repeatedly with rounds from another 88 mm gun. The crew was knocked unconscious, and recovered only to be killed by an exploding grenade. They were buried with full honors, uncommon for other troops. The English version indicates that Erhard Raus, the author, may have mistaken similar events and people, so this may be an error.

Krasnogvardeysk

Wrecked KV-1 tank, Stalingrad, Russia, Aug 1942. Note the multipule hit marks on the tanks hull and turret.

On August 14, 1941, the vanguard of the German 8th Panzer Division approached Krasnogvardeysk (Gatchina) near Leningrad (St Petersburg), and the only Soviet force available at the time to attempt to stop the German advance consisted of five well-hidden KV-1 tanks, dug in within a grove at the edge of a swamp. KV-1 tank no. 864 was commanded by the leader of this small force, Lieutenant Zinoviy Kolobanov. German forces attacked Krasnogvardeysk from three directions. Near Noviy Uchkhoz settlement the geography favored the Soviet defenders as the only road in the region passed the swamp, and the defenders commanded this choke point from their hidden position. Lieutenant Kolobanov had carefully studied the situation and readied his detachment the day before. Each KV-1 tank carried twice the normal amount of ammunition, two-thirds being armor-piercing rounds. Kolobanov ordered his other commanders to hold their fire and await orders. He did not want to reveal the total force, so only one exposed tank at a time would engage the enemy. On August 14, the German 8th Panzer Division's vanguard ventured directly into the well-prepared Soviet ambush, with Kolobanov's tank knocking out the lead German tank with its first shot. The Germans falsely assumed that their lead tank had hit an anti-tank mine, and failed to realize that they had been ambushed. The German column stopped, giving Kolobanov the opportunity to destroy the second tank. Only then did the Germans realize they were under attack, but they failed to find the source of the shots. While the German tanks were firing blindly, Kolobanov knocked out the trailing German tank, thus boxing in the entire column.

Although the Germans correctly guessed the direction of fire, they could only spot Lieutenant Kolobanov's tank, and now attempted to engage an unseen enemy. German tanks moving off the road bogged down in the surrounding soft ground, becoming easy targets. 22 German tanks and 2 towed artillery pieces fell victim to Kolobanov's No. 864 before it ran out of ammunition. Kolobanov ordered in another KV-1, and 21 more German tanks were destroyed before the half-hour battle ended. A total of 43 German tanks were destroyed by just five Soviet KV-1s (two more remained in reserve).

After the battle, the crew of No. 864 counted a total of 135 hits on their tank, none of which had penetrated the KV-1's armor. Lieutenant Kolobanov was awarded the Order of Lenin, while his driver Usov was awarded the Order of the Red Banner. Later on, former Captain Zinoviy Kolobanov was again decorated by Soviet authorities, despite having been convicted and downgraded after the Winter War for "fraternizing with the enemy." After the end of World War II, Lieutenant Kolobanov served in the Soviet occupation zone in East Germany, where he was convicted again when a subordinate escaped to the British occupation zone, and was transferred to the reserves. The battle for Krasnogvardeysk was covered up by Soviet propaganda. A monument dedicated to this battle was installed in the village of Noviy Uchkhoz in 1980, at the place where Kolobanov's KV-1 was dug in, due solely to the demands of the villagers. Unfortunately, it was impossible to find a KV-1 tank, so an IS-2 Heavy tank was installed there instead. The Soviet victory was the result of a well-planned ambush in advantageous ground and of technical superiority. Most of the German tanks in this battle were Panzer IIs, armed with 20 mm guns, and a few Panzer IIIs armed with 37 mm KwK 36 L/46.5 guns. The German tank guns had neither the range nor the power of the 76 mm main gun of a KV-1, and the narrower track width of the German tanks caused them to become trapped in the swampy ground.

Historical Accuracy Errata

The following are consensus errors or inconsistencies which have been identified with the configuration of the vehicle in question and conflict with information available on the public record. The causes for these divergences in the game are normally not disclosed and may be rooted in game balance.

* The 57 mm Project 413 was designed for the KV-1S, not the KV-1. Furthermore, it never reached prototype stage.
  • The 122 mm U-11 gun was designed for the KV-9 in a different turret.
  • The 85 mm F-30 gun was designed for the KV-220 in an englarged turret. Another 85 mm gun, the 85 mm ZIS-25, was designed to fit in the standard KV-1, but a prototype was never made.
  • Two of the KV-1's historical armaments, the 76 mm L-11 and 76.2 mm F-32, are missing.
