Work continues on the 152-mm interspecific artillery system 2C35 "Coalition-SV" and its modifications on a wheeled chassis. In recent days there have been a number News about works on these samples. The main one is the transfer of the first batch of tracked self-propelled guns to the armed forces. Now it is expected that all the necessary tests will be completed, followed by adoption.

First delivery


The armed forces became aware of the first delivery of the finished batch of self-propelled guns “Coalition-SV” on May 22, the TASS news agency reported about it, citing the press service of the Rostec state corporation. The news did without the most interesting details, but Rostec noted that the promising artillery complex surpasses domestic and foreign models in basic tactical and technical characteristics.

On May 26, news of the delivery of the 2S35 self-propelled guns was confirmed by the Ministry of Defense, represented by the press service of the Central Military District. It is reported that industry transferred to the Central Military District eight artillery complexes. In the near future, this equipment will be transferred to the troops for development. The cars were built by the Uraltransmash plant, which is part of the Uralvagonzavod NPK.

Apparently, we are talking about the first pilot batch of self-propelled guns, built at the end of last year. In the near future it was planned to transfer it to the troops for a new stage of testing. In addition, several Coalition-SVs were transferred to Alabino to participate in a future parade. It should be noted that, together with the actual self-propelled guns, transport-loading vehicles with various equipment for maintenance, etc. should go to the troops.

Alternative platform


Also on May 26, the Zvezda TV channel showed interesting shots from the ongoing tests of the 2C35-1 Coalition-SV-KSh artillery system on a wheeled chassis. In addition, cited data from the Central Research Institute "Petrel", who developed such a combat vehicle. The representative of the institute recalled the main advantages of the proposed project.

Made a small series of wheeled self-propelled guns, now used in testing. These measures are planned to be completed before the end of the year, after which the issue of adoption will be decided. Other details of the work have not yet been announced.

It is noted that wheeled self-propelled guns differ from tracked ones in greater simplicity, can be used on general purpose roads, show better mobility and have an increased resource. In addition, the combat weight has been reduced, which simplifies airborne transport. As a result, the wheeled version of the Coalition-SV is a convenient tool that can complement or even replace the basic wheeled modification.

Standard ammunition


On May 27, Techmash Corporation revealed some details of the development and production of ammunition for the new self-propelled guns. THEM them. Bakhireva, a member of Techmash, has already begun testing several shells and missile charges, which are considered standard for the 2A88 howitzer. By the end of the current half-year it is planned to receive the letter “O” - the project is entering the stage of mass production.

The issue of adoption will be decided on the basis of state tests. This stage will be completed in 2021-22. After that, the standard ammunition for the new howitzer will go to the troops.

Old and new


According to well-known data, the first prototypes of the 2S35 self-propelled guns were built in 2013 at the Uraltransmash plant and then went to the test. In 2014, a batch of 10 armored vehicles was manufactured. A few months later, their first public demonstration took place as part of the parade on Red Square. In the future, it was repeatedly reported about the imminent start of deliveries of pre-production or serial equipment to the troops.

At the end of last year, the manufacturer announced the completion of the assembly of a pilot batch of equipment and its readiness to transfer it to the troops. Then it was said about the presence of 10 self-propelled guns, which should arrive in parts of the Western military district. Now it became known about the transfer of 8 cars to the units of the Central Military District.

Thus, to date, at least 18-20 tracked self-propelled guns of a new type, belonging to different parties, have been built. It can be assumed that the latest machines, recently transferred to the troops, have the final serial appearance. Accordingly, all new samples of the full-fledged series will be similar to them.

Accurate data on the production of 2C35-1 wheel complexes is not yet available. It is known that the first prototypes of this kind appeared several years ago and are being tested. Now we are talking about a small series of unknown volumes. Perhaps more accurate data will appear in the near future.

Main advantages


The artillery complex "Coalition-SV" was created in response to advanced foreign systems, characterized by high indicators of range and accuracy of fire. With this in mind, in the new domestic project, the most modern components and solutions were applied, allowing to obtain an advantageous combination of combat and operational characteristics.

Tracked version 2C35 is based on a modified main chassis tank T-90 A machine with a combat weight of 48 tons remains mobile at the tank level. The jobs of all three crew members are located inside the hull; the fighting compartment is completely uninhabited and works automatically according to crew commands.

The Coalition-SV-KSh is carried out on the KamAZ-6550 four-axle chassis. The car chassis receives a platform with a seat for an artillery tower, hydraulic outriggers and other equipment. The crew and fire controls are in the cockpit; basic operations are performed without going outside.

Both versions of the artillery complex have a unified fighting compartment, made in the form of a large full-rotary tower. Main weapon Self-propelled guns - 152-mm rifled howitzer 2A88. It is equipped with a muzzle brake, an ejector and developed recoil devices. Used separate shots of a modular type, sent to the chamber by automation. Transportable ammunition - 70 rounds with shells of all available types. It is possible to use guided ammunition with increased range and accuracy.

Additional armament includes a remote-controlled 6C21 combat module with a heavy machine gun and the Cloud system. These systems are managed without leaving the protected volume.

2C35 is fully integrated into the Unified Tactical Management System and can receive target data from various sources. The information received is processed by the on-board unified information-command system with the subsequent release of data for firing and ammunition management. According to open data, the maximum firing range brought up to 70 km. The use of guided missiles allows to obtain high accuracy. Automation provides a rate of fire up to 10 rds / min.

Thus, according to the main fire characteristics, the Coalition-SV surpasses all serial self-propelled guns of domestic and foreign production. So far, only individual foreign prototypes can compare with it.

Future issues


Both versions of the 2S35 complex have been tested and brought to production in small batches. The main tracked modification has already hit the troops, while the wheeled one is still at the verification stage, which will be completed before the end of the year. Thus, over the next few years, having received an appropriate order from the army, industry will be able to deploy a full-scale series.

The positive effects of this are obvious. The basic version of the "Coalition-SV" will be a great addition to the existing self-propelled guns of old models. Having similar mobility, the 2S35 self-propelled guns will be able to fire further and more accurately, as well as work more efficiently in existing control loops, which will give troops clear advantages.

The appearance of wheeled self-propelled guns "Coalition-SV-KSH" in the troops will be a very interesting event, since at the moment we do not have such samples. Such a technique, as tests show, combines high combat qualities and improved mobility characteristics. In this case, there will be a choice - the execution of the fire mission can be entrusted to complexes that are better adapted to specific current conditions.

There is information about the development of the ship version of the "Coalition-SV". In this case, all the characteristic capabilities of the land system will be transferred to the offshore platform. However, this version of the artillery complex. as far as I know, not yet ready for testing.

The long-awaited news


Now exactly what is expected over the past few years is happening. After completing a number of necessary stages and activities, the self-propelled gun "Coalition-SV" enters the troops. The first batch of eight cars in the future will be followed by new ones, including larger ones. You should also expect an early arrival of similar equipment on a wheeled chassis. Naval artillery will appear the latest.

In general, in recent days, not just news appeared about the supply of various types of military equipment. This is a major event in modern stories Russian self-propelled artillery - a fundamentally new model with the highest capabilities reached the troops. It is hoped that the subsequent production and development program will not encounter any difficulties, and the Ministry of Defense will be able to regularly please the public with new messages about the “Coalition-SV”.

    I will not pour water. I will give only one example. In the spring I bought a manure car. They brought to the garden on a newfangled four-axle dump truck (KAMAZ). Well, I was delighted, we can straight out In the garden to dump. The driver answered me lightly. 2 meters did not reach the garden - the car got in! Not there - not here !!! This miracle was pulled out by the old neighboring Urals (which, for traction efforts, was caught by the fiscars of a centenary larch)! After everything is finished. A neighbor examining this miracle KAMAZ said - db Lloyds !!! It was impossible to drown, but you drowned !!! Fuck you climbed through the urea, and even through a spoon !!! Then he got behind the wheel of a KAMAZ and drove back into the garden and drove off !!! Added by - Dungsters !!! And left!
    Findings:
    1. it all depends on the gasket between the steering wheel and the seat!
    2. You can plant everything!
    3. He also Ural in Africa Ural, but better caterpillar bulldozer !!!
    Thank you for the article !!!

          Well, as it were, the AK 130 ship’s AU is all different. They receive data from the BIUS and continue to work on their own. And the rate of fire in the Coalition against the background of AK 130 is losing. 45 per barrel versus 15.

                It would be enough that the special warhead is included in 152 mm, but not in 130 mm. Although I’ll supplement it anyway, the much greater power and range of just shells, the smaller and noticeable difficulty in creating guided and ultra-long-range shells plus (and very large) unification with the land explorers.

                The stupidity is obvious, but there is no justification, I would like to hear. You demand explanations, well, I will demand justifications. What does not suit the MH, what does not suit modular loading, what does not suit booking a tower, by the way. Well, stupidity is exacerbated by the fact that on the ship’s version the trunk just asks for alteration in the first place. Guess why?

                But A-192-5P-10E already gives about 30 shots. Well, it's just nice, to compare a double-barreled gun with a total mass of 150 tons (AU - 98 tons, SU - 12 tons, a mechanized cellar - 40 tons) to compare with a 48-ton self-propelled gun weighing no more than 50 tons. And this despite the fact that on the ship the chassis with all the piers is not necessary, and weighs at least 25 percent of the mass of self-propelled guns.

                  Well, the points are:
                  1. Special warhead on a ship with its missiles and everything else is of course relevant. But how difficult is the question.
                  2. About smart stuffing and engines this is nonsense. That 130 that 152 mi a little difference. Moreover, all this is now calmly put in 80 and 57 mm.
                  3. It makes no sense to refute an illiterate refutation. MSA is your own. And the "earthly" from the Coalition to the sea does not quite fit. Need a completely new one.
                  4. Tobish MH from the Coalition with a funny, by sea standards, ammunition is normal? The mechanisms on the ship are less limited by the mass-dimensional harakieristikami. You can throw a couple of tone and increase the speed and ammunition. Once in a few. And for this we need to redo everything. Water barrel cooling may come in handy. Did you hint at him?
                  5. Hand face regularly. Helps to improve cerebral blood circulation.
                  6. I’m not comparing you. Saying that a 48-ton gun made for use on land, after imaginary alterations, could become the equivalent of a 150-ton colossus. One amplification of the GN drives is indispensable. You need to redo everything. And fundamentally.

                  No shells with special warheads. Since 2000 Officially, anyway.
                  By the way, I had a dispute with one expert.
                  He claims that there were special warheads for 130 mm. But I do not believe.

                    Do not believe the "expert". It is not possible to create a projectile in a nuclear design with a caliber of less than 152 mm purely due to physical properties. A certain compression force of the combat element is required (it must also have certain characteristics). Maybe in the future, with the development of science, they will be able to reduce the caliber, but there are suggestions that they will create "on other physical principles."

    It is a question of about the most important event in the modern history of domestic self-propelled artillery - a fundamentally new model with the highest capabilities reached the troops.

    I would say about the only event in the history of post-socialist Russia. Since 2002, quite a bit of time has passed, and already 8 units (out of the planned 12) have entered the troops.
    Hopesthat the subsequent production and development program will not encounter any difficulties, and the Ministry of Defense will be able to regularly please the public with new messages about the Coalition-SV.

    And what else remains for us? Those who were directly involved in artillery know what the success of artillery fire is made up of. It’s one thing to use the installation in exercises, it’s completely different to “demonstration performances” on some part of the theater of operations. Agree that talking about the achievements, the characteristics of military weapons is possible only after operation in combat conditions.
    One thing is pleasant - the matter has budged.
    In favor of SV, it is worth noting that such a “product” cannot be mass due to the specifics of the tasks performed. And here it is important not the quantity, but the quality of the preparation of the calculations. It remains to wish our gunners successful development and accurate shooting.
    1. I also think that the saturation with troops will not be hasty and we will read more than once “the next batch (without specifying the quantity) was transferred to the troops” ...

      Why was it necessary to capture "Dane", if everything was already known about it right from the moment of development in 1976? Or could the Czechs hide some details about their development from their older comrade and only 28 years after the start of production, having captured Dana from rodents, could we repeat the wheeled self-propelled guns? A-222 since 1988 is available if Cho.

    It’s interesting, but the car in dimensions, or not. KamAZ, he is already more than 3 meters high, and this colossus sticks out, and somewhere under bridges it may not pass. Or it’ll move through a piece of iron, maybe it’s fucking. Of course, probably in dimensions. I wonder why the truck calculator. For some reason, the reverse lamp is on the right side, so it should be on the driver’s side, it’s more convenient. Interestingly, the system has its own engine, or everything is powered from the car. So the installation consumes quite a lot of electricity, plus hydraulics, heating, cooling, and I have never seen a generator more powerful than a kilowatt in KamAZ. Behind the cabin, a compartment is visible, maybe there is a generator there. I wonder where the crew is while moving. So it is advisable that we all ride together, we need a two-row cab, but it is impossible to do this on KamAZ, we need a bonnet, I think the Urals would be preferable, and so the car with the crew should go side by side. Interestingly, the tower is armored, but the car is not.

    The main weapon of the self-propelled guns is a 152-mm rifled howitzer 2A88. It is equipped with a muzzle brake, ejector and developed recoil devices.

    If the Coalition’s tower is uninhabited, then why on the cannon an ejector? To complicate the design and increase the cost of production? what

      Most likely the power is large and there is a big impact on the design. And artillery systems, by definition, do more shooting than tanks.

        The ejector is designed to better remove powder gases from the bore and prevent them from entering the fighting compartment. hi
        Moreover, there is a greater shot and power I do not understand. request
        Moreover, the openings in the barrel for the operation of the ejector seem to reduce the overall strength of the structure and therefore indicate its greater metal consumption and requirements for materials, which again increases the cost. yes

            The muzzle brake serves to reduce the recoil of the gun after the shot, therefore, reduces the load on the recoil device. In this connection, they can be made smaller, weight and cost.
            Neither on the rate of fire, nor on anything else, he does not affect. hi

            Soot creates the amount of ammunition. Far from the idea that for tank and other shots there is a need to create new gunpowder, and therefore production. There it will pour out such money - do not grieve for mom!
            The barrel heating is again not relevant, the ammunition is fired in 5-6 minutes, in the fastest mode. But how often is it used? Especially with our winters for six months, again, "past the checkout."
            And another nuance.
            On "Armata" there is a barrel thermal insulation casing. For what? Reduces the possibility of bending the barrel when it is heated in precipitation, when the upper and lower half of the barrel are subjected to different cooling conditions, for example during snowfall or rain. And this despite the fact that the barrel is longer on the Coalition than on the Armata. From here follows the lower heat loading of the Coalition trunk.
            But according to your post, everything should be the other way around. hi

                  Once again, firing at a maximum combat rate of more than 1-2 minutes is a guaranteed failure of the gun.

                  In addition, the main firing option for our self-propelled guns is from the ground. And shells in ammunition are used to perform fire missions obtained, for example, during the movement of the unit.

                      Again. The difficulty is that every shot heats the barrel.
                      And if you try to shoot the entire BC at the maximum rate of fire, this is guaranteed to render the barrel unusable.

                      And it is precisely because of such complexity that the concept of "Fire mode" is introduced
                      Take, for example, 2C5.
                      4 rounds per minute of combat rate of fire. And he will shoot his transportable shell of 30 shells at a temperature of -30 ° C and below in 10 minutes.

                      The anti-fire maneuver is much, much shorter in time. In one minute at a speed of 30 km / h you can drive off for half a kilometer. and that’s enough

                        The “flurry of fire" mode is, however. Its essence is that for a certain period of time the trajectory of the shells are calculated so as to hit the target at the same time.

          After the shot, the trunks swing, so you can’t immediately make a second shot. The result was a very small gain, which was not worth the complication of the design to two trunks.

          Including this. No, the problem is solvable, and a solution was even proposed for the modernization of Solntsepekov. But also worth the money.

          Plus trunks. Which should have been easier, and therefore either more expensive or with less resource. Plus, in fact, a dual loading system, which with a fixed weight would reduce the BC.

          And so on.

    A caliber of 155 mm with a fixed value of the relative mass of the projectile gives an increase of 6%, i.e. 2,5 kg According to calculations, this additive, when rationally distributed between the shell of the shell and the explosive charge, increases the fragmentation efficiency of the shell by about 10%.
    At the same time, an increase in the volume of the charging chamber and barrel length to 52 calibres makes it possible to significantly increase the mass of the charge and, as a result, increase the firing range.

      Yes it does! The only trouble is that we and NATO have different approaches to measuring the caliber of artillery guns! So no matter how our 152 turned out to be more than their 155!

        The weight of domestic 152 mm HE shells of 43.56 kg is “permanent” for all models, the mass of explosives is from 5,86 to 7,8 kg, depending on the model.
        A standard NATO M795 projectile weighs 46.7 kg, while the mass of explosives is 10,8 kg.
        Unless, of course, take the old M107 shell with which it is customary to compare domestic BPs, its weight is 41,86 kg and the mass of explosives is only 5,74 kg
        PS: here it is necessary to take into account not only the caliber in mm but also the length of the projectile ...

          3OF29 weighs 45.5 kg. With 6,42 kg of metallized hexogen
          Older 152 mm shells were even heavier. For example, OF-550 weighed 49 kg. With seven kilograms of explosives

          So it goes.

            I took as a basis a line of shells for 2C19 ..
            Of course, if you take 2C5 or C-59, then here is another matter ...
            The same ML20 has the lightest OF 40kg, the heaviest the same 43,56

              What's the difference?
              We are not discussing the "ammunition line" but the imaginary advantages of the 155 mm caliber over the 152 mm.

                Of course, if you do not take into account the ancient shells with which all the arsenals in the country are littered with in case of the 3rd World War, we won’t get much difference, although here we must take into account the materials themselves from which the shells make what fragmentation they have, to increase the research of the Watertown Arsenal laboratory, for example, by comparison of Soviet and American shells in 152mm and 155mm, respectively ...

                Plus the 155th caliber is the possibility of a wide export of guns for which they even made the 2S19M1-155 with a 52m barrel, the 152nd if only those countries that still had stocks of shells from Soviet times ..

                and yet, the Americans on 58 trunks have already stepped for 100 km, and moreover, on practically serial XM907 trunks, with a shell - XM1113 and a propelling charge - XM645

    As a result, the wheeled version of the Coalition-SV is a convenient tool that can complement or even replace the basic wheeled modification.

    Everything ingenious is simple, why break your brains, invent a bicycle, at first glance it’s what wheeled commercials from a distance of one or two kilometers look like a crane based on KAMAZ, that’s what the designers thought, but they didn’t know the diseases of this crane, and why they need to be mastered by grandmas while they give it, and then bullshit it will be bullshit when the frame begins to crack and begin to cook reinforced linings. In general, I had a much greater opinion about our military designers. They would have come up with something similar to an armored personnel carrier, only more powerful and the coalition installation was added, and since it’s a crane, it’s a crane.

    Diameter according to the Central Administration of the Russian Federation: 152,4 mm (landing fit):
    NATO - 154,7mm (KP).
    The diameter of the Russian Federation Air Force is 155,9 mm (for howitzers).
    NATO - 157,9mm.
    Pressure PG - RF - 350mPa;
    NATO - 450MPa.
    The parameters of the systems and their ammunition in NATO are standardized by a joint memorandum on ballistics in caliber 155mm (JBMoU). The result was a unified series of feces of ammunition. 155mm.
    RF in caliber 152,4 mm - three shots and 3 systems respectively (Msta, Hyacinth and Coalition).
    A shell from Msta approaches the Coalition. On the contrary, it does not fit. That's the whole unification.
    So did it make sense in the Coalition to bother with a caliber of 152,4 mm?
    2,3 mm give an increase in the volume of the chamber under the explosive. Small but give.
    The caliber 152,4mm completely lacks export potential, i.e. over the hill for the money no one needs him, just a freebie. Remember that where the Shell, SU-30, T-90, etc. came from, which saved the enterprises that produced this equipment and gave them development.
    A lot has already been written about the firing range of mass-produced foreign systems and ammunition. The main words in this sentence are "commercially available." These systems and ammunition have long been available and mastered in the troops. And behind these ammunition there was a line of buyers.
    Here is an example of the fragmentation of 155 mm HE shell of the XM1218 INE PFF-DP (RDM SFR) (the shell was demonstrated in the fall of 2019 (not a cartoon, not a press release, not a presentation, not a speech).
    The shell was blown up at a firing range in front of several hundred people, broadcast on screens and followed by a guided tour to the site of the blast.
    BB - PBX 4 IM. The area of ​​fragmentation damage (mea) - 8000kv. m. The number of fragments of natural crushing - 10000pcs. GPE - 20000pcs.
    And the rear KAMAZ truck is noticeably overloaded, this can be seen in the video.
    And they are right in the previous post - the frame will collapse and the tires will burst.
    And on its side this wheeled self-propelled gun will lie louder than the Shell.
    So it turned out another "ZIL for the parade."

      About the range, you are silent about the fact that this is due to other gunpowders in the West ... with a noticeably longer range, the storage period of shells is 3 times less (I remember in 2003, 155 shells ran out in the whole of Britain .... in general ... after small aftershoots in Iraq) and higher barrel wear. Well, our desire for the ability to shoot almost royal shells ....
      On the Coalition they refused.

    I look, the platform from the t-90. It seems that it was originally planned to put on the platform from Armata. Those. ideally planned. And it would be cool if those who know described the differences between Msta-s and the Coalition. Or the possibility of modernizing Msta-s to the level of a coalition. Is such a modernization possible in principle?
    With regards to artillery shells. It seems like the most advanced shell was Krasnopol. They abandoned it or it goes in parallel ... i.e. we are talking about conventional discs or OF, because Krasnopol was reactive. In general, it would be cool to get answers to these questions. Maybe someone in the know.

      New shells with microwave ignition, large (at or above Western systems, the range of Msta was deliberately lower due to the possibility of firing old shells), an automated integrated control system, even higher automation (beyond, Panzerhaubets 2000 something like Msta, the rest are worse).

    A question for those who know and understand why we don’t want to switch from caliber 152 to NATO 155, practically all countries use it? And why do we need two types of caliber artillery 122 and 152 at once? This is not practical.

      At NATO, 3 caliber artillery:
      - 105mm - threaded system;
      - 120mm (smooth mortar) and
      - rifled mortar (based on a French mortar loaded from a muzzle) (shell with
      ready-made lead tabs on the lead belt);
      - 155mm.
      In the Russian Federation - they develop 120mm (a smooth mortar and a rifled gun) and 152mm, but they use quite a lot:
      - 100mm (smoothbore towed gun, occasionally skips during exercises, does not develop,
      finish off the old);
      - 122mm - they do not develop, they finish the old, there are a lot of troops;
      - 120mm - smooth mortar and
      rifled gun, mainly loaded from the treasury (shell with ready-made guides
      protrusions on the leading belt), but it is possible from the muzzle;
      - 152mm - in this size 3 non-interchangeable shots and 3 systems;
      - 203mm.
      Maybe there is something else (for example 130mm).
      Probably believe, let there be a raznosortitsa than undersupply.
      The picture in artillery coincides with the picture in tanks, aircraft, etc.
      The caliber 152mm has no export prospects. Variety sorters are problems of logistics, problems of production, problems of operation and repair, problems of personnel training, etc.
      World War II taught the USSR nothing, neither in the rifleman, nor in artillery, etc.
      In Russia, all problems continue to be solved by the number of people (women give birth) .... and
      with a shaky tongue and showing cartoons and people, it all bows, and some still want to repeat ...

        As for mortars, it’s understandable in general. But for what there are two types of self-propelled guns "Acacia", "Carnation", the tasks are generally the same, but different calibers, 122 mm for self-propelled guns are now useless, why not put one caliber 152.A good time to introduce calibers according to the standard of the probable opponent, moreover, they are the most common.

          The caliber 122mm does not develop, there is a consumption of old stocks of ammunition and machine resources, self-propelled guns Carnation may remain with the Marines.
          But the probability is high that it will be replaced by a 120mm cannon for a shell with ready-made leading protrusions on the leading belt (see the Burevestnik guns for the SV, and TSNIITOCHMASH for the airborne forces).
          Self-propelled guns Acacia was supposed to change Vengeance, but Acacia has not yet developed a resource, so it is still used. These howitzers have the same (unified) shot.
          It all comes down to finance.
          And for good, it’s high time to introduce calibers according to the standard of the probable opponent, moreover, they are the most common.

          And ask this question to the top leadership.
          Which, even after the Second World War (mountains of corpses), the mind didn’t have enough to switch to a new rimless cartridge in the rifleman, to develop a carbine (sn. Rifle) for it and to make a new machine gun for the Hitler’s Circular base.
          Fighting dissent, getting into dead ends or getting boilers, sawing finances in the Russian Federation has not yet left the wizard.
