Self-propelled anti-tank gun "Sprut-SDM1" received a new fire control system

39

The new version of the Sprut-SDM1 self-propelled anti-tank gun is fundamentally different from the base model. As the head of the R&D department of Kurganmashzavod Sergey Kotelevsky said in the program "Military Acceptance", the self-propelled gun received the latest fire control system.

The new fire control system allows firing not only at the target designation of the command vehicle, but also automatically aims at a target that the gunner does not see. In addition, the Sprut, based on the BMD-4, received a new power plant, an information and control system for the chassis, a new sighting system and the most modern software and hardware. Also, "Octopus" received an additional remote-controlled machine gun installation.



It is emphasized that during the tests the machine confirmed all the characteristics laid down in it.

State tests "Sprut-SDM1" began in August 2020. Earlier it was reported that the Ministry of Defense had already made a decision on the adoption of "Sprut-SDM1" into service, training commanders of a self-propelled anti-tank gun or light tank for the Airborne Forces, as this machine is also called, is already underway.

The Sprut-SDM1 combat vehicle is armed with a 125-mm cannon, a 7,62-mm machine gun paired with it and a 7,62-mm machine gun mounted on a remote-controlled module. strong points and defensive structures of the enemy, conducting military reconnaissance and combat security.

    self-propelled gun received the latest fire control system.

    The next news, as it would seem logical to me, would be that the fire control system on all Russian tanks will be replaced with a new one, radically different from the previous one.

        Since 1984, the Sprut-SD chassis has been produced, it has been used from the Object 934 (single track rollers), the layout of the engine is different (exhaust back), and so on.
        "Sprut-SDM-1" release since 2015, chassis based on the BMD-4M chassis (which, in turn, is unified with the BMP-3), according to the engine, the same, unification (exhaust to the right side), etc.

        So far, "Octopus-SDM" is being tested. They did not seem to be reported about their completion, the assignment of the design code to the product of the letter and the adoption of the vehicle for service.
        "Sprut-SD" and "Sprut-SDM" are two different machines, despite the similar names and the same gun. 2S25 "Octopus-SD" was created on the BMD-3 base extended by two rollers. The Sprut SDM has a chassis base (also extended by a couple of rollers) from the BMD-4M. Different SLAs, different possibilities.

          Machine for the Airborne Forces, respectively, specific requirements. Second: the tank gun has an increased hydraulic recoil, plus a hydropneumatic suspension on the vehicle itself. All this brings the "quenching" of overloads to the optimum.

    It would be interesting to read a comparison of Octopus-SDM1 and Lotus. Do they complement each other? Lotus is mainly for hanging fire, and Sprut-SDM1 for flat fire? The Lotus can fire guided 120mm Kitol mines. Sprut-SDM1 does not have a similar ammunition. Or does an ATGM launched through the Sprut-SDM1 barrel perform the functions of accurately hitting a moving target?

      13 February 2022 18: 23
      Such a comparison, it seems to me, does not make sense. It's like comparing the T-90 and Mstu-S. It is possible, but why?
      The "Octopus" is equipped with a shortened version of the 2A46M tank gun, completely unified with it in terms of the ammunition used. Of course, there is no ammunition similar to the Kitolov in its ammunition load, just as there is nothing like the Krasnopol in tanks.
      But this is not a lack of "Octopus". He has completely different tasks compared to the "Lotus" and comparing them, I repeat, is completely pointless.
      On the other hand, the Octopus has the ability to fire guided missiles of the Invar type, which the Lotos does not have. This complex of guided weapons undoubtedly performs the functions of accurately destroying observed moving targets.

        Well, why so categorically? After all, self-propelled guns are designed for direct fire as well. And the desire to have guided anti-tank missiles for them is quite appropriate. Another thing is that the self-propelled gun is already overloaded with sights and other systems, and additional blocks and ammunition will not make it cheaper and easier.
        But for a tank or for an Octopus, guided mines and shells are definitely not needed, the barrel cannot be raised for mounted shooting.

          You seem to have answered your own question. wink
          "Lotos", of course, can fire direct fire, but only with high-explosive fragmentation shells. On the 2S9, a 3VBK14 shot with a cumulative projectile was used to fight tanks, but on the 2S42 its use is hardly possible due to the presence of a muzzle brake.
          To fire tank URs, it is necessary to install additional aiming equipment, which is hardly possible given the volume of the SAO fighting compartment, as I know it.
          So it turns out that at least be categorical, at least not, but the tank has its own tasks and the possibilities arising from them, and the CAO has its own.
          So why compare them?

            How does the use of a muzzle brake interfere with the use of the COP? There are HEAT shells in the BC of the Sprut-B gun.

              How does the use of a muzzle brake interfere with the use of the COP? There are HEAT shells in the BC of the Sprut-B gun.

              Available. But they are still somewhat different weapons.
              I will try to explain.
              Yes, the 125A2 Sprut-B 45mm anti-tank gun uses ammunition from the 2A46M tank gun. All of them are feathered, which, however, does not prevent the use of a muzzle brake on the Octopus.
              But look at this muzzle brake carefully:

              Notice how short it is, how close its edge is to the muzzle. It's pretty easy to find a slow motion shot of a tank gun on the net. Below is a video report from the TV channel "Russia 2", in which at 1:29-1:30 it is perfectly clear that the plumage of the projectile is fully revealed, as soon as it leaves the gas-dust cloud of the shot.

              This means that the beginning of the opening of the stabilizer blades falls almost immediately behind the muzzle, which forced the designers to make such a short muzzle brake, obviously sacrificing its effectiveness. But the initial speed of 125-mm cumulative projectiles reaches 905-915 m / s and the opening of the blades occurs solely under the influence of the oncoming air flow, that is, during movement along the bore is excluded.
              Now let's move on to the interesting, that is, to 2S42.
              Pay attention to the design of his muzzle brake:

              You can clearly see how advanced it is. But the initial speed of the 120-mm 3BK19 is about 600 m / s - significantly lower than the tank "kuma".
              But that's not all. The projectile itself (it is in the picture on the left) has ready-made rifling on the leading belt, classic for this series:

              This means that it begins to rotate even while moving along the bore. Do I need to explain that under the action of centrifugal force, the blades of its plumage receive an opening moment long before crossing the muzzle and instantly set in motion upon departure, i.e. inside muzzle brake?
              That is why on SAO equipped with muzzle brakes (2S34 "Khosta", 2S42 "Lotos"), 3VBK14 rounds with feathered 3BK19 HEAT rounds are not used.
              I hope I answered your question?

      A tank gun makes sense on vehicles with tank armor, that is, on a tank. An octopus, essentially without armor, is a one-shot machine, after which it will be destroyed. And it is absolutely right to release Lotuses instead of Octopuses, they will live much longer and bring more benefits. The only use of the Octopuses is as an amphibious self-propelled gun, but such equipment is not needed in mass quantities.

    This is also another solid project that will most likely move forward.

    All in all, the 125mm caliber needs some sort of new longer-range ammunition option that could allow tank and anti-tank weapons to take advantage of range against man-portable opponents.

    This is also another solid project that is very likely to move forward.

    In overall terms, the 125mm caliber needs some new variant of ammunition of longer range, that can allow the tank and anti-tank weapons to take advantage of the range of fire versus adversaries armed with man-portable weapons.
