Why a wheeled chassis was chosen for Malva JSC: discussion of the version

Not so long ago, the Burevestnik Central Research Institute, which is developing a promising self-propelled artillery gun as part of the Sketch development work, presented the appearance of its "brainchild". It is a self-propelled artillery gun, the name of which is designated as "Malva".


The SAO 2S43 project was implemented, as stated, based on the 152-mm 2A64 cannon. At the same time, in the mode of providing open data about the project, it was added that "it is possible to install and modernized versions of the gun."

The experts' attention was drawn to the fact that "Malva" is made on a wheeled chassis. In this regard, the conversation turned to a kind of tendency in which, in different armies of the world, new and promising CAO (ACS) are created precisely on platforms with a wheel formula. In the case of Malva, this is the 8x8.1 variation. We are talking about the platform of the Bryansk Automobile Plant BAZ-6910 of the so-called 20th series. According to some reports, we can talk specifically about the modification of four-axle platforms from BAZ, which is equipped, for example, with the Krasukha-2 electronic warfare system.



In the case of Malva, they preferred to abandon the platform version from the Minsk Wheeled Tractor Plant in favor of the option from the Bryansk manufacturers.

In this regard, the question is being discussed of why the wheeled chassis was chosen for the newest domestic artillery self-propelled gun.

Several versions have been put forward to answer this question. The main one is related to the fact that with the linear dimensions of the gun, it is the wheeled platform that allows you to maintain an acceptable mass of the entire artillery complex. "Putting" 2A64 on a tracked platform will actually get the second 42-ton Msta-S ACS. The wheeled chassis makes it possible to reduce the total weight of this self-propelled artillery weapon (SAO), and, according to the official website of the Bryansk Automobile Plant, 8x8.1 platforms allow traffic on all types of roads and terrain. That is, the wheeled platform does not mean that the self-propelled passability will significantly decrease. Losing weight also means increasing speed, which is important if the "Malva" needs to be transferred in a short time to one or another section of the operation.

Recall that within the framework of the Sketch R&D, other "flower" complexes are being developed: in addition to "Malva", for example, this is a 120-mm "Phlox" based on the "Ural" truck, namely the three-axle all-wheel drive "Ural-VV" with YaMZ- 6565 with 270 hp

    Because it was originally such a task. But why an armored jacket with a coalition was installed on KamAZ, I do not understand. At the very least, you can change places between KamAZ and Base.

    There is also the question of how much our artillerymen need such a wheeled self-propelled gun, whether it came out successful, maybe it was necessary to put the 2A8 gun, it is more powerful, and the range of ammunition is richer. Our thoughts and the opinions of experts may be fundamentally different, perhaps this Malva will be created in the export version, it will not "take root" suddenly with us!

      Most likely, the ACS is being prepared for export to southern countries. There, such a layout option will be preferable for the buyer.

        Wheels are, in addition to speed and mobility, also a requirement for roads with good coverage. The American Donnie recently threatened to thrust his troops from Germany into the Baltic states! Closer to the borders of Russia, so for an old woman in Europe this cannon on wheels will definitely fit!

          I don’t want to go to school, but Fedya must, we must! Long barrel increased range. Projectile speed does not matter for howitzers, mortars, mortars. Variable charge
          War charges for rounds of ammunition loading are constant. They are used for firing cannons and can be full or reduced. The former have an extremely large amount of gunpowder for a given sample of guns, and the latter have a reduced one. Reduced warheads increase the survivability of the gun barrel when firing at medium ranges and provide a more hinged trajectory.
          In most cases, shots of separate case loading are equipped with variable warheads and much less often with constant ones.
          Live yourself in a happy ignorance. repeat

              The howitzer has a lower minimum charge. That allows her to shoot at a lower initial speed.
              This, in turn, allows for a steeper trajectory and a larger angle of incidence.

                To increase the range of charges at the gun and raise the angle to 70 - how will it differ from a howitzer? And by the way, why don't they do that? Golden mean! laughing

                        These are not small things at all. The anti-rollback ones are optimized for certain loads, the automatics of the tool are similar, the lifting-swivel ones due to the new elevation angles need others, the lower carriage is similar.

                        And even the barrel is optimized for certain loads when fired.

      Sorry! Of course, I'm not an artilleryman (another specialty). But, when "pidzhachil", had to talk to the gunners, by the way, we were neighbors in the officer's "hostel". So they explained the difference to me: the cannon is designed for "flat" fire, and the howitzer is for "mounted" fire. They had a 122 mm D-30 (if I'm not mistaken). And to the question "How do you shoot?" received the answer: "And we can do this and that!" ... So you have "howitzer guns"? "Well, sort of, although technically - we are a" howitzer "battery!

        So you have "howitzer guns"?

        Soviet "cannon howitzers" were armed with two types of ammunition, "cannon shells" and "howitzer grenades", so it is better not to interfere with this term.

        About the destination, right. But if you look at the 122 mm D-30 howitzer (38 caliber barrel length) and the 122 mm D-74 cannon (53 caliber barrel length), we find that the cannon fires a conventional projectile further (24 km) than the active-rocket howitzer (22).

        So not "formally" but really, the D-30 is a howitzer

        And here we are discussing something else.
        Modern "long" howitzers that are longer than cannons.
        Howitzer 2S35 is a 52 caliber barrel length, a 2S5 cannon is 47 calibers

      Because this is a priori a cheap option, just a towed howitzer to which wheels are attached that do not detach.
      These wheeled crafts have nothing to do with normal ACS with AZ and 10 vysr / min.

      Indeed, it is not clear why it is impossible to move it closer to the cockpit? let the barrel hang over the cockpit.

        For some reason, I also thought so. But maybe we do not know all the ideas of the designers.

        You can not.
        Where will the rollback be?
        I would have had to lift up the whole machine ...
        And how does the calculation work?
        It is not convenient to feed shells, and there is no place.

        There is also a double armored cabin and MTO .... they weigh not sickly. The weighting is probably like this

    The question in the title is not correct. It should sound like this: Why was the fearsome 2A64 chosen for Malva?

    Most likely, because the long barrel for the new guns had to be drilled with some imported machine, and sanctions were introduced, and it became impossible to purchase these machines. I think.

      Not much longer than the old 47 gauge

      Everything is simpler, there is ammunition for the 2S19 / 2A65, including in storage. There is also a production system for such ammunition.

      And for the 2S35 there are no ammunition reserves, the production system is just being created

        Again, export is better.

            Are they not cheaper?

              Accordingly, ammunition is not particularly common.

                If ammunition is also expensive, then I don't understand the purpose of this development. request
                The proposal to use it in the National Guard did not meet with understanding among colleagues. smile

                  We have about two hundred old 2A65s, which are definitely outdated and do not meet modern requirements.

                  As far as I remember, the 99th Don had regimental-level anti-aircraft artillery battalions. D-30 battery, 120 mortar battery and charger battery

                  Therefore, for Rosgvardia "Phlox" is enough for the eyes

      Of course it won't. After all, this is a prototype. This means there will certainly be changes. May be significant. For example, there will definitely not be an injector. Why is he there?
