"Malka" with a new engine will go to the troops


Until recently, Russian industry was engaged in the modernization of the 2S7M Malka self-propelled gun of special power. A few months ago it became known about the tests, and now the enterprise-developer has reported on the completion of the project. Updated equipment is ready to go to the troops.


Completion of work


On April 7, the press service of NPK Uralvagonzavod told about the intermediate results of the modernization project. The company announces the completion of the modernization project with the desired results. The Uraltransmash plant, which is part of the corporation, performed the design, and then modernized the prototype machine.

The first model, modernized by a new project, passed a full cycle of tests. All design characteristics are fully confirmed in practice. According to the results of the update, it was possible to obtain an increase in running characteristics, maneuverability, team handling, etc.

It is alleged that the first modernized 2C7M Malka model is already ready and can be transferred to the troops. In addition, preparations were made for full-scale work to upgrade equipment from combat units of the ground forces. How soon this modernization will begin is not specified.

It is necessary to recall the messages of the recent past. In mid-December, the management of Uralvagonzavod spoke about the start of testing the updated 2S7M self-propelled guns. Work on overhaul and modernization was planned to be completed in the coming weeks. Plans for 2020 included preparations for mass modernization of equipment.

According to recent reports, all of this work has already been completed. The Uraltransmash enterprise is ready to accept old equipment and rebuild it according to a new project.

New from old


The current project provides for major repairs and deep modernization of available equipment; construction of new cars is not planned. For revision they will go 2S7M self-propelled guns, which are distinguished by a rather large age and have partially consumed a resource.

The development work of Malka was carried out in the first half of the eighties, its goal was to deeply modernize the existing 2S7 Peony self-propelled guns. Ready-made self-propelled guns were launched in 1986 instead of the base Peony. Production continued until 1990, and during this time several dozen military vehicles were built.

According to open sources, now there is approx. 60 self-propelled guns of the Malka type. Their main characteristics still meet the highest requirements, but a respectable age imposes some restrictions. The resumption of production, discontinued 30 years ago, is impossible or does not make sense. For these reasons, several years ago it was decided to launch a deep modernization project.

The first results of such a program have already been obtained. One instance of 2S7M underwent major repairs and modernization with the replacement of parts of equipment. In the near future they plan to return it to the army. Then, the expected process of mass restructuring of equipment will begin, which will ultimately allow to increase the combat qualities of artillery formations.


"Malka" with a new engine will go to the troops

Repair and upgrade processes are likely to affect most of the existing fleet of self-propelled guns. This will allow continued operation of the Malok for a long time, and with the maximum possible results.

Domestic and modern


Last year, NPK Uralvagonzavod specified the main features of the new project. It provides for the restoration of the technical readiness of a combat vehicle, the replacement of parts of units and the installation of new devices. Replacement is made both for reasons of obsolescence and for reasons of import substitution.

The need to switch to domestic components most of all influenced the completion of the armored chassis. The V-84B diesel engine and mechanical transmission with planetary rotation mechanism and hydraulic control were produced by Ukrainian industry. They were replaced by Russian-made units. A similar adjustment was carried out in a number of other systems, such as energy supply, etc.

Import substitution and modernization have affected the on-board electronics complex. Under the replacement went the equipment of internal and external communications. New means of receiving, processing and issuing data for firing are used. Changed viewing devices for the crew.

Replacing the power plant and other equipment does not require serious alteration of the hull. Bulletproof booking remains the same, the layout does not change. The chassis retains the original design. One of the main differences between the modernized Malki and the base Peony was the availability of routine monitoring equipment. With the next modernization, it remains.

The artillery unit and related equipment were not modified. The 203 mm 2A44 gun shows outstanding performance and does not need to be replaced. The ammunition stacks and the loading mechanism were improved during the development of the 2C7M Malka project and still show sufficient characteristics.

Positive effects


The expected serial modernization will positively affect the condition and potential of the existing 2S7M self-propelled guns. This will allow the continued operation of such equipment for a long period of time upon receipt of all the necessary combat capabilities.

On the service life, first of all, the performance of major repairs will affect. All Malki are of a considerable age and may need restoration work. Of great importance is the replacement of imported components with domestic ones. Now, the operation, repair and maintenance of equipment will not face problems in international relations.



Updating communications and control has a positive effect on the combat capabilities of self-propelled guns. After modernization, Malka can quickly receive and process information from the command post and provide data for firing.

In addition, expanding opportunities for interaction with artillery intelligence. So, last fall it was reported about the first experiments on the use of non-modernized 2S7M self-propelled guns in conjunction with reconnaissance UAVs. The drone discovered the target and determined its coordinates, and according to these data the self-propelled gun dealt an exact blow. Probably, new devices on board the self-propelled guns will allow receiving target designation both from UAVs and from other available sources

The direct fire capabilities of the modernized Malka remain the same - very high. The 2A44 gun is capable of using a wide range of separate-loading shots with 203-mm shells for various purposes. It is possible to use several types of high-explosive, cluster and concrete-piercing shells. Depending on the type of projectile, shooting at a range of up to 30-35 km or up to 45-47 km is possible.

Awaiting Delivery


After modernization, the 2S7M Malka self-propelled gun remains a special-purpose firearm capable of hitting particularly important enemy targets at tactical depths. At the same time, new units and assemblies make it possible to simplify operation and expand combat capabilities - without the need for a fundamental restructuring of part of the systems and assemblies.

So far, the troops have not received a single upgraded Malki, but the delivery of the first model has already been planned, followed by new ones. The rearmament of artillery brigades will take several years and will have the most noticeable consequences.

    The V-84B diesel engine and mechanical transmission with planetary rotation mechanism and hydraulic control were produced by Ukrainian industry.
    Right now I read and a lot of questions arose. Neither this engine, nor transmission elements for this engine were produced in Ukraine. Similar, but for their two-stroke, boxer engines of the TD family were produced there.
    And the tracked chassis “Object 216M”, developed by the design bureau of the St. Petersburg Kirov plant, is largely unified with the tracked chassis for air defense systems - S-300 (“Object 830, 831, 832, 833, 834, 835”)

      Strange, but Ukraine and the State Department are not involved in the causes of modernization (deep?). What a twist. Cyril, in this case, probably, is also not to blame. I just reprinted the UVZ press release. It remains to the military prosecutor's office to check which such engines have been replaced by the "Orthodox" V-84D.
    2. And I was immediately struck by the eyes - "... il skis do not go, il I ..."?
      Which V-84 in Ukraine? !!!
      Yes, if production was there, the neighbors would have been rich for a long time!

      Ukrainian industry is a factory, Malysheva? Before the war, B2 was released there, but then their push-pull opponents began to drive there. And all the descendants of B2 drove Chelyabinsk as far as I know.
      What it is? Somehow it became bad in VO, a low class, not reading the game.

      But on .... why shoot from a barrel artillery at such a distance? In my opinion, using tactical missiles in this case will be both cheaper and more efficient. Because how to shoot from a barrel artillery at such a distance can only be guided by a projectile in the presence of external horizontal control (drones, satellites - underline what is necessary). The cost of such a shot will approach (taking into account the design of the projectile, which can be thrown at such a distance) to the cost of the rocket. But you still need to upgrade the gun for this - more precisely, to create a new one, because everything will have to be modified (or rather redesigned): guidance systems, a barrel, a charging chamber, etc. There is no need for this - in its tactical niche, “Malka” as a weapon is also good in its current performance.
      "Malka" is a strange Jewish name
      Malka is not only a Jewish female name (by the way, the name of the mother of Prince Vladimir the Holy (Baptist of Russia) - Malush is also from the annals of Malka), but also the name of the rivers in Russia, I am inclined to believe that the modernization code of the self-propelled gun 2S7 “Peony” was chosen according to the name of one of these rivers.

          It turns out that the modernization of this class of weapons is a logical step after the actions of the Americans to reduce the power of nuclear charges in the troops. They are developing a new one, and ours got the old one with the same characteristics from the zashnik.
          In Kaliningrad, they must be located, from there all the goals are at hand.

          Why are you talking about this stuff everywhere? Jews really want to declare themselves also Rurikovich, or is it just that the name Vladimir traditionally does not give rest? The mother of Vladimir was called Malush, and the brother of Malushi was called Dobrynya. Was Dobrynya a Jew too?

        Malka, remove Malka, is a locksmith term. When sharp parts are machined on abutting parts. For example, when welding in a butt of sheet metal, or gluing wood, plywood. Still, maybe someone paid attention, there are wheel bearings with a removed malk on the inside.

        MLRS

        Most advantageous are shells with a bottom gas generator. They allow you to take advantage of artillery (less starting weight) and missiles (range).
        This is due to the fact that missiles, at low speeds, do not have enough compression of the jet stream with atmospheric gases and the fuel is spent inefficiently. Guns allow you to skip this moment.

          for firing at a long range (if the task is not to hit the areas) you need adjustable ammunition. In the MLRS shell this is implemented easier and more efficiently. Yes, and the impact power is higher, the MLRS battery per unit time will release much more shells than the Malok battery

            Equally.
            Moreover, for a small correction, you can use pulsed transverse motors (centimeter shell), which slightly increases the cost of the shot. You can use the plate brakes, which open at a certain moment, adjust the range.

              not at all. Firstly, the electronics of a corrected artillery shell are more expensive. than jet electronics, since the first one experiences a large overload when fired

                        In any case, the rocket has the best weight ratios, despite the fact that it has an engine (in fact - powder bombs)

                        Starting mass for acceleration of which fuel is consumed
                        110 and 280 (reduced by burn-out) kg, respectively. Furthermore, warheads of 110 and 100 kg.

                        For a shell with a bottom gas generator, for the range of the rocket, the mass would be added to a couple of tens of kg.

                        The design of the warhead itself does not play a role, since this is a question of the need to hit the target.

                  But monsters like Malki have outlived themselves

                  Hello, your arguments are clear, it is difficult to disagree with them, but there must be at least some reason to modernize it? Why do you think this is done?

                    I think, simply because they are (something about 60 units). And there have been a lot of shells for them since the Cold War, including - special ammunition. In addition, the latest technology is once again delayed in our arrivals.

                    But, I do not see any particular utility from the system in modern conditions. In the 60s - 70s, the place of Malki (Peony) was understandable. Firstly, it was a means of acquiring tactical nuclear weapons. Secondly, the missiles did not provide the necessary accuracy of hitting enemy targets, were expensive and difficult to operate, their mobility left much to be desired. 152 mm self-propelled guns did not provide a sufficient firing range.
                    But now, with the qualitative development of self-propelled guns with 6-inch guns, the appearance of UAS and special ammunition in the caliber 152 (155) mm, the development of MLRS, combat helicopters and UAVs, the relevance of the system, in my opinion, is not high.

        This is due to the fact that missiles, at low speeds, do not have enough compression of the jet stream with atmospheric gases and the fuel is spent inefficiently.

        There is no "low speed"
        Take, for example, Grad. By the end of the active section of the trajectory, the RS accelerates to a speed of 715 m / s. For comparison, the D-30 at full charge has an initial HE shell velocity of 690 m / s

        It just makes the PC much smoother, with less acceleration and less load on the projectile

            "Malka", for the delivery of 17,8 kg of explosives to a range of 37 km, 43,2 kg of gunpowder is consumed. Or 2.4 kg of gunpowder per kilogram of explosives

              You completely forgot about the fragmentation part.

              You need to calculate the total weight of the warhead, which can cause damage in accordance with the type of target. It makes no sense to compare devices with different fragmentation and high explosiveness. The weight of the Malki warhead is comparable to the Hurricane.

              You apparently were led to my reservation on the specific gravity of explosives .... But this is true only with the same ratio of the mass of explosives and fragments.

                  To the D-30 there were (probably, now there are) shells that could explode at a given height, covering a decent area with needles (small arrows with stabilizers). The results were good.

              They only forgot about the difference in the cost of "gunpowder" in an artillery cap and a solid propellant jet engine. An artillery projectile is always cheaper than a missile, except when a smart missile is made from a missile, as the Americans did in the Long Range Land Attack Projectile (LRLAP) for Zumwalt-class destroyers.

        The bottom generator increases range but decreases accuracy.
        Without the supply of such a seeker shell, the bottom generator is meaningless.
        And GOS, control wings, etc. increase the cost of the projectile 10 times.

        Are you talking about the off-design mode of operation of the nozzle so sloppy? The design mode of the nozzle is when the static in the jet is equal to the static in the external environment. Naturally, with these dimensions of the aircraft, making such a nozzle is unrealistic, therefore, in any case, the outflowing jet will be underexpanded, it continues to expand, slips the equilibrium state, becomes overexpanded, the narrowing begins, ending with the Mach disk, then everything repeats for 4-6 calibres until the turbulence does not eat all this beauty, the so-called barrels. This is very clearly visible when the fighter takes off in the afterburner.

          I’m not so much about the dynamics of the flowing stream, but about the primitive difference of the gun barrel .... The walls of the barrel create perfect compression and gas pressure effectively disperse the projectile. In atmospheric conditions, where at zero-low speed missiles, there is no sufficient raid of calm air, which with its mass creates a virtual cannon barrel (at a decent speed). That is, at the start, only the reactive component works, which is very small (as in a vacuum).

            Well, what can I say - internal ballistics from external differ greatly. It is not necessary to transfer the movement of the projectile in the barrel channel to the movement of the rocket, no “virtual barrel” is necessary to explain the movement of the rocket. It was believed in the early Tsiolkovsky era that a rocket flies, relying on a stream of gases, which, accordingly, rely on air. From this it was concluded that in airless space jet propulsion is impossible. And Tsiolkovsky showed that air is not needed here - Newton’s third law and everything flew anywhere.

              Almost the way it is.
              In the atmosphere, the higher the air pressure (density), the more efficient the rocket engine. And the higher the speed, too - this is equivalent to an increase in density due to the mass of passing ambient air over a period of time.

              This does not cancel the work of the factor of atmospheric density and velocity.
              That’s why they try to make other hydrogen engines for vacuum, because kerosene is completely unsuitable (low reactive component of thrust due to low flow rate).

      Malka (adaptation) - joiner's and locksmith tools for marking and transferring angles [1], drawing parallel lines. Consists of two parts fastened together by a clamping screw. The thicker part (block - base) is pressed against the workpiece, a thin part (line) is marked. Sometimes between two parts of the malki a scale is applied for measuring angles. Large fry can be used in construction work.

    In addition, expanding opportunities for interaction with artillery intelligence. So, last fall it was reported about the first experiments on the use of non-modernized 2S7M self-propelled guns in conjunction with reconnaissance UAVs. The drone discovered the target and determined its coordinates, and according to these data the self-propelled gun dealt an exact blow. Probably, new devices on board the self-propelled guns will allow receiving target designation both from UAVs and from other available sources

    And where is the "extension" here?
    The guns firing from the PDO never received information directly from the UAV from anyone.
    There is always a "gasket", or even not one. In the case of Malki, this is at least SOB.

        It's not about UAVs, it's primarily about the ability to visually observe the fact of hitting a target and cease fire after that. Drone is only one of the ways, and not the best.

    The need to switch to domestic components most of all influenced the completion of the armored chassis. The V-84B diesel engine and mechanical transmission with planetary rotation mechanism and hydraulic control were produced by Ukrainian industry. They were replaced by Russian-made units.
    here the author lazhanul so lazhanul. Initially, Peony had a 780-horsepower B-46-1 engine, at Malka it was replaced by an 840-horsepower B-84B. Both diesel engines are all-Russian, produced by ChTZ.
    Why write articles if you do not understand the issue at all?

    Weapons for past wars. After the first shot, it will be destroyed.
    It is not clear where to apply it now. Maybe only in operations as a Chechen company.

        it’s easier to take apart for scrap than with Turkish drones or artillery

            Yes.
            "Turkish scrap" is guaranteed to destroy the "Malki" in the conduct of counter-battery

            neither the Syrian aviation nor their own artillery crushed a single Turkish battery, and the air defense proved to be practically powerless against Turkish UAVs.

            Perhaps the right organizing entries have now been made, but we all saw what happened

              UAVs flew according to the Sochi Accords and monitored the area over Idlib. Then they suddenly struck, and at the rear and on the approaches to the battle line. And the safety of Turkish batteries is not a matter of a battery fight contract. They did not even dig in. For aviation, this is an easy target. But Turkish aviation is not there. This is a matter of politics and the death of Turkish fighters.

            The Turks corrected the fire of their artillery from drones in real time. Battery commanders saw a picture from drones and fired, immediately seeing the results of the hits. It was a master class of modern warfare.

              The batteries of the Turks were not affected ...... although they could have been affected. The Russian group showed this whole company in Syria ... and bombed and corrected and scouted.

                Scouted, corrected, bombed, but not in real time. Except those cases when they simply sent people with walkie-talkies to the cutting edge. Usually late from half an hour to several hours. On stationary objects it worked. In a dynamic battle, as was the case in Idlib, this is not enough.

              "... a master class of the modern war ..." - recall the Bumblebee UAV-1 (flight with cameras and infrared equipment 1989), Bee-1T (first flight 1990, in 1995 5 Bees flew to Chechnya, 10 sorties - 8 combat , total flight time 7,5 hours, losses - 2 Bees). Bumblebees and Bees were created precisely for reconnaissance purposes and adjusting artillery fire. You can argue for a long time why the Bees did not take root ... They created the first Bumblebee in 1983, following the example of Israel in the 1982 war - the Turks "did not discover America."

                I did not claim that the Turks were the first.
                There were many military inventions that did not take root in
                developing countries.
                Turkey has effectively and widely deployed intelligence
                artillery spotters and strike UAVs in a real military
                operations. Against enemy infantry and armored vehicles.

    Three Rheinmetall artillery shells set new range records during a fire test at the Alcantpan Test Site in South Africa on November 6, 2019. “During the event, three new records were set for the maximum effective firing range from various guns. The 6 mm G155 howitzer (barrel length 52 caliber) reached the longest range ever achieved with a conventional artillery shell of this caliber - 76 kilometers, at that time how a 52-caliber PzH2000 self-propelled howitzer cannon threw a projectile at 67 kilometers. A field howitzer with a barrel length of 39 calibers shot a projectile at 54 kilometers, "the company reported.

        Escalibur, why not .... and if it shoots at 70, then at 40-50 it will hit for sure.

      We look at Wikipedia, we see the 2S7M Malka weighing 45 tons, including the gun’s weight of 14.6 tons, this means that the gun’s conveyor itself weighs 30 tons, the question is, can the conveyor be made lighter, for example, less than 20 tons? so that the total weight of the machine was less than 35 tons. The answer is, if you abandon the undertaking by all means shoot from the conveyor itself, then you can, because vehicles are mainly designed for transportation, shooting with such calibers is undesirable, but you can and should carry guns on the roof, but you need to shoot, the cannon was removed from the roof, put to the ground and shoot. it’s necessary to think of dragging a 203mm cannon onto the roof and wagging !!! By the way, in the mountains, weapons are sometimes transported to pack animals and it’s never occurred to anyone to shoot a mortar from the back of a horse
