“Devil’s Dozen” – the only attempt in the USSR to combine a medium and heavy tank

In the fall of 1941, German troops inexorably advanced, laid siege to Leningrad and approached Moscow. At the beginning of the war, the Soviet army suffered irreparable losses in equipment, which could not be reimbursed in a short time. It was then that the idea of ​​creating a fast tank with enhanced armor arose.

Hello tankers! Today we propose to deviate a little from the game theme and broaden the horizons with interesting facts of the tank building of the Great Patriotic War.

This is a new format for articles on the site, so at the end we ask you to take part in the survey.

Now let’s get back to the events of 1941. At that time, the front needed tanks, and especially heavy ones. KV series performed well at the first stage of hostilities, but their number was not enough

Difficulties in operation were also clearly felt, and the process of manufacturing and adjusting tanks was long and difficult.

Despite the fact that the KV-1 and KV-2 were practically nothing, except for the reservation, were better than the cheaper, easy-to-manufacture and operate thirty-fours.

In December of the same year, a “universal tank” project appeared, designated as KV-13

Its essence was to create a middle-class combat vehicle that would combine:

  • the ability to quickly maneuver;
  • the possibility of a frontal attack;
  • simplification in production.

As you can see the task was not easymake the tank more perfect and efficient, wherein reduce resource costs and time of creation… We will not load you with the details of all the tests, so let’s go straight to the main results.

The main breakthrough was the first attempt in the USSR tank building industry to create a cast VLD hull.

According to eyewitnesses, the KV-13 was remembered for the fact that broke every time when leaving the factory, that is, every day. For a month of testing, almost half of the parts had to be replaced in it. It failed the first test:

  • insufficient protection against 88 mm guns;
  • weak weapons;
  • the commander’s congestion required expanding the gunner’s turret.

In February 1943, there was unexpected event, which forced the acceleration of work on the KV-13 – near Leningrad, the Wehrmacht army launched the Tigers… During this period, the People’s Commissariat was headed by Zaltsman. Being a superstitious man, he decided that the name should be changed. “Devil’s Dozen” (outside the vowel nickname KV-13). Therefore, the next two prototypes of the KV-13, which were planned to be significantly modernized, received new names: IS-1 and IS-2

In the very first tests, both vehicles significantly surpassed the KV-1S. In the future, they did not return to the KV-13 project, but the experience of working on the “Devil’s Dozen” was a good help to create a line of heavy tanks “Joseph Stalin”.

KV-13 in World of Tanks

In the game, the tank belongs to the medium and is located at level 7, being a transitional link between the ST and TT classes. Being “underweight” he has one of the best bookings among classmates… Moreover, he decent dynamics and good maneuverability

It has weak top gun, as was the case with the first prototype. And the most low visibility among STs due to the fact that the tower had one hatch for three crew members (historical design imperfection is respected).

KV-13 the developers did it historical, but absolutely irrelevant in modern randomness. Its main plus – the ability to explore a branch of another class, skipping the initial levels.
