Self-propelled gun "Condenser-2P" (index 2А3, USSR)

31



The self-propelled gun "Condenser-2P", index GRAU 2А3 - heavy self-propelled unit weighing 64 tons, capable of sending 570 kilogram projectile at a distance of 25,6 kilometer. Not commercially available, it was all made 4 guns. For the first time, a self-propelled gun was shown at a parade on Red Square in 1957. Shown SAU created a sensation among domestic viewers and foreign journalists. Some foreign experts have suggested that the vehicles shown during the parade were fake, designed for the effect of intimidation, but in reality it was the real 406-mm caliber gun system that was shot at the test site.

The creation of a 406-mm self-propelled gun of special power in the USSR began in the 1954 year. This ACS was designed to destroy conventional and nuclear projectiles of large industrial and military facilities of the enemy, located at a distance of more than 25 kilometers. In any case, the USSR began to develop the 3-x nuclear superorders: guns, mortars and recoilless guns, caliber significantly exceeding the existing atomic guns. The huge caliber chosen was the result of the inability of the Soviet nuclear scientists to produce compact ammunition. In the process of development, in order to ensure secrecy, the artillery system was given the designation “Capacitor-2П” (271 object), and later the gun received its current 2А3 index. The ACS was developed in parallel with the 420-mm self-propelled mortar 2B1 "Oka" (object 273), according to the decree of the Council of Ministers of the year 18.04.1955.

The artillery part of the ACS (guidance and loading mechanism, swinging part) was designed by TsKB-34 under the control of I.I. Ivanov, here it was assigned the index CM-54. The horizontal aiming of the gun was carried out by turning the entire ACS, while the precise aiming was carried out using a special electric motor through a turning mechanism. Vertical guidance of the gun was carried out using hydraulic lifts, the weight of the projectile was 570 kg., The firing range was 25,6 km.



Due to the fact that there was no suitable chassis for mounting such a large gun in the USSR, the OKBT of the Leningrad plant named after Kirov for self-propelled guns 2A3 "Condenser-2P" on the basis of components, parts, technical solutions of the heavy chassis tank T-10M (object 272) a new eight-wheeled chassis was created, which received the designation "object 271". When developing this chassis, the developers focused on the need to perceive large recoil forces when firing a shot. The chassis they developed had descending sloths and hydraulic shock absorbers that were supposed to partially extinguish the recoil energy. The motor-power plant for this self-propelled gun was borrowed from the T-10 heavy tank, almost without any changes.

In 1955, the plant number 221 completed work on the creation of the 406-mm experimental ballistic trunk CM-E124, which was carried out testing of the shots to the CM-54. In August of the same year, the first fully equipped artillery part of the SM-54 gun was ready at the factory. Its installation on the chassis of the Kirov factory was completed on December 26 1956. The tests of the ACS “Condenser-2P” took place from 1957 to 1959 year at the Central Artillery range near Leningrad, also known as “Rzhevsky range”. The tests were carried out in conjunction with the 420-mm self-propelled mortar 2B1 "Oka". Before conducting these tests, many experts were skeptical that this self-propelled artillery gun could survive a shot without destruction. However, the 406-2 “Capacitor-3P” 2-SAU quite successfully passed the test by mileage and shooting.

At the first stage, tests of the ACS were accompanied by numerous breakdowns. So when fired, the recoil force of the CM-54 cannon mounted on the ACS was such that the self-propelled caterpillar cannon rolled back a few meters. When carrying out the first firing using simulators of nuclear projectiles from the ACS, sloths were damaged, which could not withstand the enormous recoil forces of this weapon. In a number of other cases, cases were noted with the equipment installation falling apart, disrupting the gearbox anchorages.



After each shot, the engineers carefully studied the state of the material part, determined the weak parts and components of the structure, and invented new technical solutions to eliminate them. As a result of such actions, the design of the ACS was continuously improved, the reliability of the installation increased. On the tests also revealed low maneuverability and maneuverability ACS. At the same time, it was not possible to defeat all the defects found. It was not possible to completely extinguish the recoil of the gun, when fired the gun drove back a few meters. The angle of horizontal guidance was also insufficient. Due to its significant weight and size characteristics (weight about 64 tons, length along with the gun - 20 meters), it took a significant amount of time to prepare the positions of the 2А3 ACS "Condenser-2П". The specified accuracy of firing the guns required not only accurate guidance, but also thorough preparation of the artillery position. For loading the gun used special equipment, while loading was carried out only in a horizontal position.

4 copies of 406-mm ACS “Condenser-2P” were made, all of them were shown in 1957 during the parade on Red Square. Despite the skepticism of a number of foreign military and journalists, the installation was militant, although it had a number of significant flaws. The mobility of the artillery system left much to be desired, it could not pass through the streets of small cities, under bridges, along country bridges, under power lines. According to the parameters and in its firing range, it could not compete with the divisional tactical missile "Luna", therefore, in service with the forces of the SAU 2А3, the "Capacitor-2P" never arrived.

      The large caliber was chosen exclusively, because of the tactical YAZ, in 640 mm, they could not make less.

      In the USA, there were also similar projects. 240 mm self-propelled guns T-92.

        No, it’s gigantomania. An attempt to achieve the result by primitive means, on the forehead, increasing the caliber. It can and should be otherwise.OTR.
        According to these parameters and in its firing range, she could not compete with the divisional tactical missile Luna, therefore, she did not enter the armament of the SAU 2A3 Condenser-2P troops.

        The tactical missile system 2K6 "Luna" was put into service in 1959. It was removed from service in the 82nd. Well, and later, in the early 70s, 9K79 "Tochka" appeared ...
        Well, here's even cooler - "Oka".

          Not so simple.
          "73 missiles were launched with different types of warheads (the 29th launch was unsuccessful - 2.5 km instead of 10 km due to inaccurate ballistic tables, the 72nd launch - a rupture of the front solid propellant rocket at the start due to a powder checker defect)"
          AS is simpler and more reliable. But a more complex "trigger", if I may say so.
          "The time limit for reloading a rocket from a transport vehicle is 60 minutes ....."

          At that time, tactical missiles were a novelty; the barrel artillery was well known. In the end, she lost, but at that time it was a logical decision (the creation of speakers and Sau). hi

      The fruit is NOT gigantomania, but the desire to equip the receiver artillery with nuclear munitions of the required power. It turned out with smaller calibers later. In practice, in past wars, designs and large calibers were used to a limited extent, but their time passed.

    Typical "iron kaput".
    It is not clear what tasks this self-propelled guns could solve, especially considering the fact that aviation and tactical missiles were developing rapidly at that time.
    No wonder it didn't go into production. The same Luna M complex was probably more mobile, passable, and hardly more expensive.

    After each shot, the engineers carefully studied the condition of the material, identified weak parts and components, and came up with new technical solutions to eliminate them.

    among other things, this is the improvement of both engineering and production technologies

      What is the minimum firing range for this gun? I strongly doubt that it is capable of direct fire at close targets, and also at moving targets.

    Stunned, what a weapon! Proud of our gunsmiths! The only thing I didn't understand about this thing (and with the "flowers" is also not clear) is the absence of a separate lowering plate behind with a set of hydro and pneumatic compensators for the perception of recoil. The chassis has been reinforced ... that's all. It's a strange story ...

    This was our forced response to the Americans, who had previously put into service the Davy Crockett recoilless gun, which fired an over-caliber mine with a tactical nuclear charge. Their firing range was about 5 km, the calculation was actually suicide bombers, but no less. The gun was mounted on an all-terrain vehicle platform with all the ensuing mobile advantages.

    This weapon is ideal for shelling a city before an assault; for a nuclear charge, the range is clearly not enough.

      Sorry, I do not agree with any of your words.
      The ideal weapon for firing at squares are the multiple launch rocket launchers. If you need to hit specific targets, for example, tactical missiles or weapons like this one:
      http://rpg1.ru/view47.html
      And there are many other such systems.
      And this "condenser" is ideal only for throwing human labor into the wind.
      As for the firing range, it is quite sufficient for tactical nuclear weapons. If anything, the "Msta" range is even less, but it is considered as a carrier of tactical nuclear weapons. American "nuclear" M-65 guns had a firing range of 22-28 km, also no more than this "capacitor". For strategic forces, the range is certainly too small. But this was out of the question initially. The disadvantages of this self-propelled guns are not in the firing range, it is just on the level.

        You are missing one point. When the "Condenser" was created, the troops did not yet have tactical missile weapons capable of delivering a nuclear weapon with due precision. The country's leadership did not begin to put eggs in one basket, and allowed the parallel development of missile and artillery delivery vehicles. With the appearance of the first, work on the "Condenser" was discontinued.

        Design of the Luna 2K6 began in 1956, and the Condenser in 1954

    She didn’t shoot anywhere, or rather, but only once. From the recollections of the technical opponent of the project, the head of the testing department of the Kirov Plant, OKBT, Leningrad, Yury Mikhailovich Mironenko:
    "... Among the overwhelming majority, as they say, of designers from God, the OKBT had a considerable number of lazy people, hack-workers and figures who, by chance sweating, were in a hurry to appear to the authorities. In my opinion, the weakest link before Albert Kazimirovich Dzyavgo arrived there, earlier worked in the Kolomenskoye KBM with the famous B.I. Shavyrin, there was a settlement department.I will only talk about two cases in which I had to voluntarily take part as an opponent to personally verify my complete technical illiteracy .
    The first case was a vivid example of the carelessness of the work of the counters, who "not enough" took into account the length and the huge dynamic pullback force acting on the tracked chassis when firing an 406 mm rifled gun. This without any calculations was visible when looking at the 271 object, but the meters, apparently, were staring in the opposite direction at that time.
    The 271 object (SAU "Condenser-2П") made its first and last shot at the Rzhev artillery range a couple of kilometers from tram ring No. 10.
    So, a self-propelled gun in a firing position. Crew, designer, testers and military in concrete shelter meters in 40 from the gun. Shot! The impression, as Arkady Raikin said, is specific, and even too much. Visibility is zero. Everything that covered the earth in a radius of 50 meters is in the air. And the 64-ton self-propelled monster that fired the 570-kilogram shell is not visible. The nerves of the lead engineer of this object can not withstand stress, and he rushes to the place where the machine should stand.
    Four people, and I am among them, follow the same path. As we move forward, the dust gradually dissipates and we, involuntarily slowing down, stop in deep thought at the sight of what remains of the formidable self-propelled guns. In order not to completely upset the “leader,” I decide to get out of sight. He and without me - “opponent”, was not sweet.
    Structurally correcting the “mistakes” made in the process of creating the 271 object was useless, although they were undertaken. In the end, the work was completed with a shot and the stage of “combing” prototypes for participation in parades on Red Square. In the 1960 - 1963 years, at military parades in Moscow, they marched alongside the stands for “guests” and made an indelible impression on “some people” (see photo). This was a US response to information about their creation of the 280 mm atomic gun.
    There was a cold war, and both warring camps misinformed each other as best they could.
    In this particular case, an unconditional victory was won not only over a probable opponent, but over a historical, evil and treacherous enemy. It is only a pity that the many years of work of talented workers of the Volgograd factory "Barricades" and the Leningrad "Kirov factory" ended to no avail.

    But, as they say, a negative result is also a result. Thanks to the experience gained from the results of this work, the unique 203mm self-propelled artillery mount “Peony” (2С7) was adopted by the same factories and design bureaus in record time.
    In the creation of Peony, I was no longer an “opponent”, but a direct participant, for which in 1975 I was awarded the Order of the Red Banner of Labor.
    Made in metal and donated to me by the Kirovsky Zavod, a copy of the self-propelled guns "Peony" has been standing in my apartment in the most prominent place for many years. "
