Anti-tank mastodons: SU-152P and Object 120 "Ram". USSR

Anti-tank mastodons: SU-152P and Object 120 "Ram". USSR

Self-propelled artillery mount SU-152P was developed in Sverdlovsk on the basis of SU-100P units and had the designation "Object 116". The self-propelled gun was intended both for striking from a closed position, and for fighting tanks the enemy, a very powerful 152,4-mm M-53 gun had a horizontal angle of 143 °, which provided sufficient maneuverability for anti-tank warfare, and the transportable 30-round ammunition made it possible to shoot well .. But, not everything was so rosy, despite to lengthen the chassis by one rink, the self-propelled unit weighing 28,7 tons was too easy to recoil such a powerful gun.


Therefore, we had to install a rather exotic looking slit muzzle brake, which helped to reduce the return to a reasonable value, but I believe that it was possible to forget about the inconspicuous firing with small elevation angles. Powder gases from such a construction should, in my opinion, unmask the gun even on asphalt.





SU-152P was not accepted for service. At that time, there was no need for an SAU of this type working from a closed position, and from that point. VET machine had a bunch of irrecoverable flaws. But, it should be noted that the designers of UZTM for this did not calm down ....



120 Taran object

It is time, apparently, to bring together everything that is available on the most powerful anti-tank SAU, "Object 120", it is "Taran". So, I’ll say right away that it seems to me that this machine is unmatched by the muzzle energy of an armor-piercing projectile. 18.5MJ (12.5kg with speed 1720м / s) - modern tank guns are noticeably more modest. And, I will note in addition - modern smoothbolks for tanks are also less accurate, but the X-NUMX-mm M-152 cannon has a rifled barrel, that is to say, very heap. However, nothing is given for free - no wonder this super-powerful car is only in the museum hall



But it all started well. When at the beginning of 60-x it turned out that the armor-piercing caliber shells of tank guns D-10T, D-25 and M-62, which are armed with medium tanks T-54 and T-55 and heavy tanks T-10 and T-10M, cannot to pierce the frontal armor of either the hull or the turret of the American tank M-60 and the English “Chief” - the Soviet military leadership hastily initiated several parallel projects at once. A super-power SAU, new smooth-bore and rifled guns with OBPS and ATGM, new projectiles to the old guns - in general, everything that came to mind could come at the same time. The self-propelled gun "Taran" was created in one of these areas. The gun developed by OKB-9 with an incredibly long 59.5-caliber * (9045 mm without a rather large muzzle brake) barrel pierced with an 2000mm armor plate 290mm thick, which made the new self-propelled gun almost super-armed, - at that time there were no tanks capable of withstanding such a blow. And even if someone could stand it out of the new ones, it would hardly be able to retain its combat capability after such a blow.



Of course, this monster weighed a lot, but the chassis from the SU-152P completely coped with it. That, in fact, is not surprising - after all, the “Taran”, in fact, was the same SU-152P with a closed tower and a modernized gun of the same caliber (6 "). In general, the self-propelled gun came out pretty light - only 27 with a tail tons, and if it were not for a huge muzzle brake - probably, they would have famously jumped when firing.

However, the lightweight, but even the installed rammer did not make the work of charging in a compact turret particularly easy - with an armor-piercing projectile still coming back and forth, since loading is separate, but with the CFS, in 43kg (according to other sources, "only" 35kg ), yes in motion ... It will not seem a little, I assure you.



Apparently, due to the extreme weight of the barrel, the developers did not even plan to install a stabilizer for firing on the move, it was supposed to use self-propelled guns only from the scene and from ambushes - especially since the maximum thickness of armor did not exceed 30mm, what kind of attacks there ...

All this together led to the realization that the time of extensive development, justified during the war, had already passed. While the self-propelled gun was tested, it turned out that a similar result could be achieved with the aid of an ATGM transported by one person, and if you need something of a barreled, smooth-bore D-81 gun with a caliber of 125-mm and one and a half times shorter - with the same two kilometers it breaks through OBPS 270mm armor.

It turned out that no specialized PTU SAU, it turns out, is not needed - it was time for tank fighters and smooth-bore guns with OBPS. Therefore, the mighty "Taran" went straight to Kubinka, to the BTT museum, where it remains to this day ...

    First, you need to clarify the chronology.
    In 1946, the GSh and SU 100P began to be developed.
    In 1949, on the basis of the GSh Su100P, they made the BTR-112, extending the hull by 640 mm and adding one roller to the side.

    This seven-shot GS, was called GM 123.
    And on his GSH, all the rest of the product was created.

        It turned out that no specialized tank destroyer, it turns out, is not needed - the time has come for missile tank destroyers and smooth-bore guns with OBPS. Therefore, the mighty "Taran" went straight to Kubinka, to the BTT Museum, and it remains to this day ...

        This is so, thought and planned in the era of global wars.
        And in an asymmetric war, a self-propelled guns 152mm ,, Taran ,,, with a new 152 mm gun, with a barrel length of not more than 28 calibers. With 30 mm of abuse, DZ, KAZ, is excellent

        The howitzer of the Second World War, of course, can hit the tanks on direct fire, but it will not become anti-tank. The Germans put it at the base of the third groove. As many as 24 pieces were made: StuIG 33B, and the Czech 38 (t) sIG 33/1 Grill, the more of them, and also on the first and second grooves, there was a very popular gun.

        Something you have with a flair. The Germans never did such self-propelled guns. Yes, there were waffentragers, which in the end served as an example for the creation of the SU-100P, but this is completely indirect.
        In any case, Ferdinand was not standing nearby.

    Wow! The most fearful slaughterhouse that I have seen. This article is only a hundred years old, and the author could at least slightly expand it, and not engage in copy-paste. Tell me where the legs grow from the platform, and how great it turned out in the end. That the SU-100P, created under the impression of the trophy waffentrager Ardelt, served as a donor for a huge number of domestic self-propelled guns and other combat vehicles. In addition, the story of the SU-152P, as it seems to me, without a description of the same SU-100P and SU-152G will be incomplete.

      And you find the info .. about GSH GM 123.
      Everywhere in the descriptions on "" SU 100P chassis. ""
      And this is not true (I repeat) the chassis is extended by 640 mm and one more track roller is added.
      Excellent GS, almost 60 years in operation, and technically not outdated in the 21st century.

          Added one track roller, increased load capacity.
          Lengthened the chassis, added space in the housing for installation, equipment.
          Therefore, they changed the name to the universal GSH GM 123, which became the basis for, a platform for so many cars, for various purposes.
          In the West, such a GS, not when it was not and is not now !!!!!

            They created excellent guns after the Second World War, it’s a pity that the traitor, No. 1 Khrushchev, destroyed it all.
            And the presence of so many objects on one tracked platform is simply admirable, a modular platform.
            In the West, this idea was realized only in the 21st century.

              Naryl still on the 120th http://russianarms.mybb.ru/viewtopic.php?id=1554
              and interesting info:
              It seems that the M-69 was smoothbore.

              In the aforementioned book "Combat vehicles of the Uralvagonzavod. Tanks of the 60s" by S. Ustyantsev and D. Kolmakov on the Taran self-propelled guns and the cannon, the following is mentioned about the beginning of work on this topic (pp. 123 - 124):

              ... According to the given tactical and technical requirements, the gun had to have armor penetration of at least 300 mm normal or 150 mm when the armor plate was tilted 60 degrees to the vertical at a distance of 3000 m. The direct range of the shot at the tank was set to at least 2500 mm, but preferably - 3000 m. After some experiments, the 152,4 mm smoothbore gun M-69 developed by Perm Plant No. 172 was selected. And a link to the RSAE. F.219. Op. 1. D.349. LL.126-127, 138; ...

              In addition, the corporate book on the history of NII-24 (now OJSC GNPP Region in Moscow) states the following:

              But one of the main moments in the life of NII-24 related to this period was, perhaps, the beginning of work on completely new ammunition-shots with feathered armor-piercing-projectile shells (BPS) for smooth-bore tank and anti-tank guns.

              This area later became one of the main ones that determined the face of the institute - the only one in the country that is developing this type of ammunition. Looking ahead, we can say that not a single organization in our country designing or trying to design such shells has been able to create samples of this type and put them into mass production.

              The creation of BPS for smoothbore guns made it possible to obtain significant superiority over similar types of weapons of a potential enemy and for a long time to maintain priority in this area of ​​military equipment.

              Work on the creation of the first BPS began in 1956 by order of the Ministry of Defense of the USSR, and since 1957 it took place by order of the USSR Council of Ministers and was carried out as part of two research projects ...

              After the end of the research work, where the main performers were the chief designer and head of the department V.V. Yavorsky, leading engineer Yu.F. Zuev, designer V.A. Leontiev and other employees of the department, another R&D ("Taran") was assigned, which already provided for the creation of a self-propelled installation with smoothbore a cannon and shots to it with armor-piercing, cumulative and high-explosive fragmentation shells.

              General management of this work was carried out by the chief designer M.Yu. Tsiryulnikov (Perm Engineering Plant).

    All this together led to the realization that the time for extensive development justified during the war had already passed
    This is the main reason. ATGMs have already gone, it’s much easier and without recoil, and even cheaper, where they weren’t mounted, but the Dragon missile tank didn’t go into the series, there’s nothing. As the chassis was equipped with BMP, BRDM and GAZ-69 easily coped. Here he is at the Military History Museum of Artillery

    It seems to me that everything depends on the amount of propellant charge. The grooves of course slow down, but the anti-aircraft artillery has an initial flight speed of bp quite high. Still shoots high. The main thing is that the trunk could withstand. Yes, and the survivability of the trunk is likely to be small. request

    It looks like anti-aircraft artillery is not enough. I found a little later. The development of anti-aircraft guns of caliber 152mm with SSP was conducted in the postwar years. The technical project of anti-aircraft guns in 1949 was presented by OKB-8 under the name KS-52. Key features of the KS-52 project:
    - firing speed not less than 10 r / min;
    - the mass of the used projectile - 49 kilogram;
    - total weight of the implement - 46 tons;
    - The initial speed of the ammunition - 1030 m / s.

    The article is interesting, but I do not agree that our T-54, T-55, T-10 could not penetrate the frontal armor of the M-60. This is overkill. From my youth I am fond of studying our and foreign technology. There were many familiar specialists and never heard of a similar problem. After the war, we had tremendous experience in tank building. Yes, and the M-60 was not a chip, and the T-10M most likely did not pierce the forehead of the M-60, it would just rip off its tower if it wasn’t a mistake for me with a 122mm shell.
