Screening project tanks "KV" and T-34, proposed in November 1942 by the commander of 203 gas stations of the 57th Army, Lieutenant Colonel Shakhverdyan.

Technical description of the modernization of the armor of the tank "KV" and T-34.
Modernization of tank armor consists of the following elements:
1. In enhancing tank armor and reducing penetration.
2. In increasing the possibility of ricocheting shells.
3. In defense of the turret of the tank from jamming.
4. In the protection of the chassis.
5. In strengthening the frontal part of the ram.

The proposed wavy armor on the hull of the tank and the tower is optional and available. Additional wavy armor in thickness 30 mm. The height of the crest of the wave from the inner wall of the armor 150 mm, and from the outer wall 120 mm. The distance between the walls 300 mm.

On the turret of the tank, the armor undulation runs horizontally, which reduces the direct hits of projectiles when the turret rotates, and also reduces the air resistance when the tank moves. The front front part of the tower should be round with a radius from the center of rotation of the tower, which increases the possibility of rebounding and reduces direct hits of projectiles in the frontal part of the tower.

On the side, front and rear sides of the tank hull, wavy armor is inclined-vertically. When a projectile hits a tank, the armor will be wavy in length due to its oblique-vertical position, the projectile should ricochet, which reduces direct hits. When a projectile hits a tank of transversely wavy armor, it collides with a number of protruding armor waves or ricochets, or, having broken through part of the waves, loses its ability to penetrate further. With a direct hit of the projectile in an additional wavy armor and its penetration, the projectile will lose the ability to penetrate the main armor.

Protection of the tower from jamming is carried out by a ring-shaped shield, which is located on the tank hull, covering the lower part of the tower. The height of the inner vertical plane of the shield 50 mm. The width of the lower plane of the shield 100 mm. The outer lateral plane of the shield must have a slope not less than the slope of the wavy armor of the sides of the tank.

Protection of the undercarriage is carried out by hanging on the side of the wavy armor of individual armor shields on each side of 4 pcs. Armor shields must be hinged for ease of maintenance on running gear repair. From the inside, the armor plates are fastened with latches, which prevent them from swinging. Hinged shields should be with a slope equal to the slope of the side armor of the hull. The cross section of the shields is the same as that of the additional wavy armor.

The buffer-ram of the frontal part of the tank is made of the same wavy armor, as indicated above. The upper part of the buffer is a continuation of the front additional wavy armor and protrudes the tracks forward on 400 mm, and the width of the buffer is equal to the distance between the tracks.

Decrease in air drag ???))) On the KV tank ??? Made fun of

[Civil]

Against cumulative charges

[Poppy]

yes, at a speed of 5 km it is very important

[rennim]

It’s quite an interesting idea. Apparently it wasn’t used due to low-tech production or insufficient efficiency for such a mass of armor.

[Bigriver]

Front creo from the reserve commander small a shelf
"Fluffy" to the already weak transmission of the KV and 34 would have crawled much faster.

[Tankist_1980]

A very controversial idea ... And the maintenance of the engine compartment? Yes, and on HF its own armor is a good plus, it had its own good shielding option.

[Poppy]

nevertheless, it is an indicator of what people thought about improvement, about victory
even though many ideas seem ridiculous, but even then education left much to be desired, many and 10 classes did not finish

[shelva]

And if you "dress up" in two layers - it will be even more invulnerable. But what will become of speed and agility?

[Tankist_1980]

Nothing good ... Yes, and where can I get so much metal? The front needs more tanks ...

[Aleks tv]

In the military battle, where Zinovy ​​Grigorievich Kolobanov knocked out the 22 fascist cars, it seems his KV-1 also had additional 25-mm armor screens ...
And this is 20 of August 1941 of the year, and not November 1942, as indicated in the article.

Additional screening has been used before.
Extra armor does not happen.


Respect for WWII tankmen ...

KV-1 with additional protection. 1941

The date is in the document.

The date is in the document.

Good day, Vadim.

So I do not argue.
I wanted to say that shielding was used before the 1942 year.
If I put it poorly - then I apologize, I didn’t want to be clever.

And the infa in the article is interesting, the material is rare.

KV-1 with additional protection.

It was the 2 period when the T-34 massively installed additional side armor.

1 period
Plant number 112 "Krasnoe Sormovo" (Nizhny Novgorod), produced 68 T-34 tanks,
the hulls and tower of which were equipped with bulwarks.
It was assumed that they would protect the tanks from German cumulative shells.
However, it was not possible to verify this - in the first battle almost all shielded in this way
combat vehicles
were hit by conventional armor-piercing shells of the 75-mm anti-tank guns of the enemy.
After that, they threw the screen venture.

T-34 with on-board and optional reservations.
The model was recreated according to the drawings of the approved model.

Testing the interaction of infantry and T-34 tanks with additional armor

(production of the 112 Krasnoye Sormovo plant). Leningrad Front, Autumn 1942

Marshal Konev in his memoirs recalls:

"During the Berlin operation, the Nazis managed to destroy and knock out eight hundred or more of our tanks and self-propelled guns.
Moreover, the bulk of these losses are in battles in the city itself.
In an effort to reduce losses from faustpatrons, during the fighting we introduced a simple but very effective means -
created around the tanks the so-called shielding: sheets of tin or sheet iron were hung over the armor ...
Why did you use this shielding so late?
Apparently, because they practically did not encounter such widespread use of faustpatrons in street battles,
and in the field they weren’t particularly considered".

[Mister X]

2 period
The losses of Soviet tanks from a manual anti-tank orge in the Great Patriotic War reached during the battles in the city of 70%.
Therefore, at the end of the war (beginning of the 1945 of the year) mesh screens from cumulative projectiles of industrial production began to be put on the T-34.
Since practically no one had done this before, the Germans had a rumor that ours welded nets from beds.
[This statement still finds a fertile audience not only in the West, but also in our country - see, for example, "The Encyclopedia of Tanks", Harvest, 1999].
The "Faustpatron" cumulative grenade, exploding on the screen, blew it to shreds, but left only a melted funnel on the main armor,
which tankers with the black humor of people, every minute looking into the eyes of death, called "the witch's suck."

(from the memoirs of the commander of the 11th Guards Military Technical Regulations V. Mindlin "The last battle is the most difficult")
"There is a car with tightly shut hatches, from it through the armor you can hear the screech of the rotating umformer of the radio station.
But the crew is silent ...
Does not respond either to knocking, or on the radio. In the tower, a small, a penny-sized, melted hole,
- The little finger will not pass.
And this is "Faust", his work!
The screen in this place is torn off, a concentrated explosion hit the armor ...

T-34-85 opposite the Branderburg Gate in Berlin.
In the photo, mesh screens of 5-mm wire are visible.

Reconstructed picture of one of the screen options.

As a defense against Faustpatrons at the end of 1944 - beginning of 1945, IS-2 combat vehicles were also equipped
anti-cumulative screens, which were made and installed mostly by handicraft forces
tank repair units made of thin metal sheets of mesh and even Bruno spirals flattened by tank tracks.

IS-2: mesh screens from 5-mm wire are visible.

[monolit55]

agree armor never happens

[kafa]

the protection of the tank turret from jamming was paid attention to on the T-34 in the conditions of front-line rembats. it's no secret to hit with a blank and the tower will go crazy. welded on the so-called "shoulder" and the problem was removed

[svp67]

This option is still better than the one that suggested Tsygankov for T34
