Object 476: experimental tank KKB named after Morozov

15



In the seventies, more than twenty thousand modern tanks, which, according to many experts, were much superior in technical standards to Western models. This fact allowed the Warsaw Treaty countries and the Soviet Union to achieve qualitative and quantitative superiority over the NATO army in equipping the warheads with the best armored vehicles.

At that time, the main advantages of Soviet tanks were: a smaller mass and low silhouette, the existing guided weapons complex, a smaller crew, the presence of an automatic loader, reliability in operation and ease of use. The Soviet leadership in tank equipment with domestic samples lasted until the 90-s.



In the nineties, modified tanks “Leopard-2А6”, М1А2SEP, “Leclerc”, “Challenger-2” entered the foreign armies, which led to a decrease in the military-technical level of Soviet tanks in relation to Western models.

The main arguments of the "pessimists" were the assertions that domestic tanks have weak reservations and therefore are lighter, have many weakened zones in frontal projection, have worse ammunition compared to Western models, and also have insufficient application angles weapons. In addition, the Soviet tanks installed engines of low power and poor maintainability.



But any arguments can be refuted by specific actions. So, back in 70-s, the Kharkov military designers together with the production workers created a tank - the so-called 476 object, which combined the security and fire power of heavy tanks and the mobility of medium ones.

The 476 object was planned as a prototype. It was created on the basis of the T-64A and, as conceived by the designers, was to become the basis for testing and installing the 6TD engine systems.

In the production of this model, a new protection scheme was applied - multi-layered booking, as well as a loading mechanism was installed and many interesting design findings were tested. It was this tank that later became the basis for the creation of new modifications of the T-64 and T-80 tanks.



It should be noted that the T-64, having become the main battle tank for many years, determined the development of tank building for several decades to come. Further development of the T-64 allowed the creation of modern combat vehicles T-90, T-72, T-80 and Oplot.

But back to the base model. The first sample of the tank project "object 476" appeared in 1975 year. The creators of the new combat vehicle boldly changed the shape of the turret, used the method of combined armored frontal booking (the essence of the interesting decision is that a filler consisting of armor plates filled with polyurethane is placed in special cavities). In 70, this decision was revolutionary in the field of armored vehicles. Not for nothing, a somewhat modified version of the base model tower was subsequently installed on T-80U tanks, the production of which was established at Kharkov and Leningrad factories. According to Kharkov specialists, these tanks managed to provide protection similar to 600 mm of ordinary armored steel. Due to the fact that the rangefinder 1-X21 was mounted on the turret, it became possible to install the Cobra guided weapons complex on combat vehicles. These sights were also installed on the T-64B and T-80B production tanks and on their modified models for quite a long time. The designers eliminated another drawback of the seventies tanks - the new 6TD-1 engine was installed on the new series of tanks. Thanks to the new engine, the forty-ton tank was able to develop speed up to 70 km / h on the highway.

The tactical and technical characteristics of the “476 object” had the following parameters: year of manufacture 1979, weight - 41,5 t, crew of 3 people. Overall dimensions in mm: length 9530, width 3580, height 2210. Armament: 125 mm cannon, mm 7,62 machine guns and 12,7 anti-aircraft mm. Armor - 20 ... 600 mm. Engine power 1000 hp Maximum speed - 67 km / h. Power reserve - 600 km.

Military tests of the new base model were successfully passed in various climatic conditions. Despite the heavy turret, the tank had increased maneuverability. According to test results, the new 6TD-1 engine was recommended for mass production. Due to the high continuity of the design with the previous serial 5TDF engine, it was possible to use the already well-developed technology and the existing equipment for the mass production of 6ТD-1 at the Kharkiv plant. V.A. Malysheva in the shortest possible time.

By order of the Minister of Defense of the USSR from 21 December 1983, T-64А, T-64АК (commander), T-64Б and T-64БХNNUMX with 1ТD-6 engine were adopted by the Soviet Army.

However, the tanks of this basic model were released no more than 5, and today not a single tank in this series has survived. Production of 6TD-1 in serial volumes was launched only in February 1986, due to the fact that it was needed for the production of new T-80U and T-80UD tanks.

Tanks have always been the "cementing link" of the combat orders of the ground forces. Therefore, the constant work of designers and industrialists to create new powerful, well-protected and armed combat vehicles will ensure the security and independence of the state.

    Just an experimental T-64, one of the many attempts to bring it to mind without touching its chassis.

    1. "KhKB named after Morozov" is actually the organization of the KhKBM named after Morozov, and stands for "Kharkiv Design Bureau for Mechanical Engineering named after A.A. Morozov"
    2. "In the seventies, more than twenty thousand modern tanks entered the Soviet troops annually" - this means that over the 70 years they produced 200000 tanks, but Mr. Boval is a science fiction writer .... in ten years, it was possible to produce 20000.
    But in general, the article is not about anything, a rough redirection from other sites.

      Yeah, it doesn’t work.

      The Warsaw Pact tank fleet consisted of 53 Soviet tanks and another 000-12000 East European tanks.

      Moreover, the machines of the first generation - T-54A and T-55 - accounted for 38% of the fleet of the Soviet Army and 85% of the fleet of the Union armies, and you can not name them modern.

      1. The GSVG had 5700 tanks, another 2000 vehicles were in the first echelon of the reserve.
      2. Czechoslovakia had 2650 tanks.
      3. Voisko Polish totaled 3100 tanks.
      4. The Hungarian army had 1300 tanks.
      5. Romanian army 1300 tanks.
      6. Bulgaria - 1900

        Now, my jaw dropped too belay when I thought about where 200 thousand tanks made during the 70s were buried, although maybe they didn’t bury them and they drove them to Ukraine? That Ukraine is still selling tanks for 20 years. wink

      That's right. Valery Boval was a good writer, but it would be better to go into the genre of science fiction.

    Our tanks have always been better adapted for the Real War, despite the "lag" in some parameters.
    There are two schools of tank building this is Our German. The rest either copy, or try to develop means of counteraction

    Somehow, everything is very crumpled and slightly turned upside down, and most importantly, a bit out of tune in which the car was conceived ...

    The 476 object was a continuation of the 430, 432, 434 series.
    It was experimental, it worked out new components and mechanisms, which, in the future, found their application about the construction of the T-80UD.

    Yes, interesting material and quite rare.
    Thanks to the author.

    As for the 20.000 annual supply ... to put it mildly not quite right.
    From 1945 to 1985, 100.000 tanks were built all over the world, including 60.000 in the USSR.
    That's something like this, if memory does not fail.

    A very beautiful tank !!!! ..... So what ????? With what fright T72 .. T80 descendants of this tank. Well, in principle, "object 476" is a further modernization of the MS-1 tank. Well, Kharkov two-stroke engines ..... As a matter of fact, like so many two-stroke engines. These are .... very bad engines ... There is one advantage, the working stroke is carried out in one revolution of the crankshaft. and 4 strokes in 2 revolutions, well, it seems the power will be 2 times higher ... But alas ,,. For small 2 strokes, benefit, lack of a lubrication system, lubrication in fuel, the only plus. And then solid cons.

      as well as a large specific power per unit mass, less weight, higher compactness (in vertical projection), the ability to work in a wide temperature range;

      Cons - a relatively high wear rate of some parts and the general technological complexity in production, which is leveled when setting up the technology.

    then about 90, when the Leclerc really appeared, but not m1a2sep and 2a6 - this is already 2000, and then it carries about 73g and 79g about 476, and 86g is the t-64. where does the author buy weed? he has a poor supplier, an urgent need to change !!!

    In the seventies in the Soviet troops annually received more than twenty thousand modern tanks

    Come on, remove the word "annually" and the phrase takes on a completely reliable meaning. repeat
