Hello tankies,
Welcome to our "Know Your Steel" series of articles. The following articles are going to be dedicated to interesting info and trivia about the tanks we have in game.
A bit of side view on them. We will not go too technical or too deep and will try to provide a fun to read material.
Enjoy in the article.
You can read the first part here, if you have not done so earlier.
KV-2
It was near a city of Raseiniai where Germans had first encountered a unit equipped with the Soviet KV heavy tanks.
2nd Tank Division from Soviet 3rd Mechanised Corps attacked and overran elements of the German 6th Panzer Division on 23 June.
The Germans Panzer 35(t) tanks and antitank weapons were practically ineffective against the Soviet heavy tanks—some of them were out of ammunition, but clashed with and destroyed German antitank guns by literally driving over them.
Attempts to destroy these armoured giants concentrated on first immobilising them by firing at their tracks and then by tackling them with artillery,  AA Guns, or by blowing them up at close range by high explosive charges of the Sticky Bomb type.

On 23th and 24th June 1941, a single KV-2, tasked with blocking the path in Southern Lithuania, at a crossroads in front of the city of Raseiniai, had managed to cut off elements of the 6th Panzer Division which had established bridgeheads on the Dubysa river. It stalled the Division's advance for a full day.
Germans were in big problems, they lost their entire supply truck column.
Positioned in the middle of the crossroad, this KV-2 had first knocked out the German light tanks, such as Pzkpfw 35(t). As a response Germans brought and mounted the PaK 38 50mm gun, despite hitting the target seven times, the end result was negligible, and the guns were destroyed.
The airstrike was not approved, not for a single tank. The famous 88mm Flak gun was brought to be used. KV-2 was attacked by a variety of antitank weapons, until it finally ran out of ammunition, and was destroyed.
The KV-2A (German designation) appeared during January to February 1940 and mounted a 152mm M –1938/40 L/20 howitzer in a high box turret with all-round traverse, upon the KV-1 hull.
This vehicle was found to be operationally ineffective due to the inability to traverse the turret when on an incline, to provide anti-tank fire and to fire on the move. It was usually fired from stationary and concealed positions.
The 10.8 tonne turret caused an excessively high silhouette of 4.14 meters, as against 2.66 meters for the KV-1. It brought the weight up from 43.5 tonnes to over 51.7 tonnes. The projectiles were those of the corps artillery 152mm howitzers and gun-howitzers.
Two men (for a total of 6) were added to the crew to handle them. The gun had low velocity compared to the M-1937 corps gun of the same calibre, but the Soviets said that the KV-2 proved quite successful against the Mannerheim Line, against which it fired concrete piercing shells.
Since the KVs were produced at the large Kirov plant in Leningrad and were coming out in the later part of 1939, the 2s were ready for use in the late February of 1940 - Steamroller that terminated the Winter War.
If KV-2s were a success in positional warfare assaults, they were a notorious failure in the mobile campaigns fought against the Germans in the summer of 1941.
KV-2s were in action as early as the third day of the German attack (June29) at Soposkinie in Poland.

KV-2B. During 1940 a second model was produced, the KV-2B which had a new turret and wider tracks, being based on the newer KV-1B chassis. The model was taken into service, but showed little improvement over the first version.
A flame-throwing version of the KV-2B was produced in limited numbers.
Several experiments were conducted as well.
During 1943, two experimental variants were developed: KV-2-1 with the 85mm anti-tank gun of the KV-85, and the KV-2-2 with the new 122mm anti-tank gun. Even these models failed to meet the requirement of tank assault gun or self-propelled artillery; no further development of the KV-2 is known to have taken place.

It is a game after all :)
Although we strive to historical accuracy in the game, sometimes certain aberrations are necessary for the sake of gameplay.

It's finally here and it's the KV-2!
.
A fascinating tank with mixed results on the battlefield, due to extreme weight it was very prone to suspension failure. I've (probably) read somewhere that a lot of them simply broke down during the Winter War, mostly due to the conditions. There are a couple of pictures from German army of captured KV-2's being tested and later used in combat, I'll have to search my bookshelf to find them and if I do I'll post them here.
.
And one thing that I never fully understood (neither do the authors of those books mentioned above), why to heck did they mount a machine gun on the back of the turret? Is there a logical explanation or is it one of the famous "soviet extra equipment"?

Yes they were known to break down.
Machine gun at the rear of the turret is an old concept. Japanese were employing it in most of their tanks.
Basically you traverse the turret and use the weapon you need at the moment, you can also cover your rear from infantry approach. Kind of impractical on tanks with slow turret traverse.

I like this tank. It burns very quickly when lit up properly.

Well if we really had to stick to facts, this tank would have a flat-ground requirement for turret traversing, artillery mode, and of course, instant disabling of the whole crew upon hit. It's not the case, but i bellieve having a T6 tank able to put out of combat nearly any tank in the game, in one mere shell...well i do believe gameplay might be affected ;)

It's defence against infantry trying to attack from behind, ve useful against sticky bombs or "molotov cocktails". It wasn't very effective while shooting, but the soldiers were afraid to attack the tank's rear so it bought some time...

It coul'd be of interest know tha a platoon of captured KV2 should have spearheaded the landing on Malta besides a swarm of M6/40 light tanks.

They should have been deployed from Siebel barges.

Hmm... KV-2 was indeed tested during Winter War but it had no impact on terminating the war.

 

However, according to some sources 4 KV-2 tanks (armed with 152mm M10 guns) were quickly produced and tested at Mannerheim-line. Tank platoon was led by experienced senior liuetenant Petin, drivers from Kirov plant and rest of the crew were assigned from 20th armoured corps.

 

In first engagement, one of the KV-2's got hit 48 times with no penetrations.

 

Finns did encounter one KV-2 later during continuation war. This time however, KV-2 was demolished by 60kg of TNT. Tank was totally destroyed...

I have a little question about this tank,i heard rumor that the kv2 wasn't able to shoot with his turret at 90°, because it may have damage the turret ring and other things.

 

I didn't find historical proof of that, is it totally a legend or not ?

I have note come across a historical confirmation of the said, either.

Myth. Actually, according to my sources (Book: Punaiset Panssarit), one of the first test firings was to test if tank would tip over when firing turret at 3 o'clock. It didn't....

Maybe a mis-interpretation about the turrets near impossibility to rotate unless the tank is nearly level due to the turret bearings ?

It can be the explication of this myth, do you have any source about that ?
