Since 2015, the AU-220M Baikal remotely controlled combat module (DBM) has regularly been shown at exhibitions. This product is equipped with a 57-mm automatic gun 2A91 high power, which should provide him with a sharp increase in combat qualities. It is planned to use such opportunities in several promising projects - both Russian and foreign.

New opportunities


It is well known that the main reason for the emergence of DBKM "Baikal" was a kind of crisis in the field of light armored vehicles. Most of these machines are equipped with automatic guns of 30 mm caliber, but they themselves are protected from this weapons. Accordingly, to combat them, tools of increased power and increased caliber are needed.



The product AU-220M was developed by the Nizhny Novgorod Central Research Institute "Petrel" and was first presented in 2015 at several domestic and foreign exhibitions. It is an uninhabited tower with machine-gun and cannon weapons, storage and supply of ammunition, fire control devices, sights, etc. Defeat targets is provided by a 2A91 gun and a PKTM machine gun. In the future, the introduction of a missile system is possible.

Baikal was originally created as a universal DBM suitable for installation on different chassis. In this regard, the main units are placed in a single housing, occupying a minimum volume inside the carrier machine. The latter has certain requirements. So, for mounting, a landing flange with a diameter of 1740 mm and a load capacity of at least 3650 kg are required. Also, the chassis must withstand loads when firing.

As theoretical and design work has already shown, a number of domestic and foreign armored combat vehicles meet similar requirements. Thanks to this, several models of equipment armed with Baikal have been created, and new ones may appear in the near future.

Russian development


Already in 2015, the possibility of mounting the AU-220M module on the chassis of the BMP-3 infantry fighting vehicle was shown. This combination of the base vehicle and weapons allows you to create several types of armored vehicles of different classes and for different purposes.

The first appeared version of the BMP-3 called Derivation, developed by the Uralvagonzavod NPK. The full-time fighting compartment was removed from the armored car, and a new DBM was mounted instead. This led to a sharp increase in combat characteristics and to the expansion of the range of tasks. In particular, the possibility of an effective fight against both ground and air targets of various types was mentioned.

Later, the “Derivation” project was developed. At the exhibition “Army-2018”, the first public display of the BMP-3 in version 2C38 “Derivation-Air Defense” took place. An armored vehicle with an updated AU-220M module is intended for military air defense. Fire controls have been refined to more effectively solve such problems with the 57mm 2A91 gun.

In 2016, the industry showed a modernized version of the BRM-3K Lynx combat reconnaissance vehicle, also updated using the Baikal module. Together with the DBM, the armored vehicle received new optoelectronic devices suitable for reconnaissance missions.

Since 2015, it has been repeatedly mentioned that Baikal is fully compatible with the promising heavy unified platform Armata. Subsequently, a corresponding project was developed, and in 2018, the public was first shown a finished prototype of this kind. The AUB-220M DBM of the latest version, known as the “Dagger,” was installed on the chassis of the heavy T-15 infantry fighting vehicle. A characteristic feature of this modification of the Baikal is the presence of guided missiles that complement the powerful 57-mm gun.

So far, the T-15 with Baikal was shown only at the exhibition site. However, in the near future it will be shown in motion. Recently, the Ministry of Defense reported that such equipment will take part in the parade on May 9. It should be noted that previously BBMs with AU-220M in Red Square were not shown.

Foreign samples


The combat module with a 57-mm cannon is of interest not only for Russian designers and military. There is already an international project involving the installation of the Baikal on a foreign chassis. In addition, in the future, work may begin on a new machine of this kind.

In 2016, the Barys 8x8 armored personnel carrier equipped with the Baikal model was shown at the KADEX exhibition in Kazakhstan. This pattern was the result of triangular cooperation. The chassis was designed by the South African company Paramount Group (originally named Mbombe 8) and manufactured by a joint venture of Kazakhstan Paramount Engineering. The layout of the armament complex was presented by NPK UVZ.

It was alleged that the Barys with the AU-220M could enter service in the very near future and go into production. However, so far this has not happened. Baikal remains at the testing stage, and until the completion of these works the release of Barys with enhanced weapons is not possible. KPE is waiting for the completion of testing and is ready to continue work on a joint project.

At the beginning of February, Russian industry presented at the Indian exhibition Defexpo-2020 a number of modern developments, including DUBM AU-220M. On the eve of the exhibition, Russian Minister of Industry and Trade Denis Manturov spoke about the possible emergence of a new joint project using Baikal. Russia suggested that India develop a promising IFV capable of carrying such a DBM. The opinion of the Indian side on such a proposal is still unknown.

In the context of joint projects, one can recall the Atom wheeled infantry fighting vehicle developed in the framework of cooperation between the Russian Uralvagonzavod and the French company Renault Trucks Defense. This armored vehicle received a combat module BM-57 with a 57-mm automatic gun. It seriously differed from the modern AU-220M, but showed the fundamental possibility of equipping wheeled armored infantry fighting vehicles with increased caliber weapons.

The Atom project has not been developed. In 2014, the French side refused to work together due to a change in the political situation. However, some ideas and solutions could find practical application. Less than a year after this, the Petrel Research Institute showed the AU-220M combat module.

Wide range of equipment


DBM AU-220M "Baikal" was developed just a few years ago and still has not left the test stage. At the same time, the industry managed to create several options for the module and work out a number of military vehicles with its use. The possibility of installing a new product on several chassis of domestic and foreign production with the receipt of BBM for various purposes was shown. In addition, the appearance of new armored vehicles, including joint development.

The prospects of all developed combat vehicles with Baikal directly depend on the progress of work on the combat module itself. According to domestic media reports, the development and testing of this product is nearing completion. Thus, in the near future, the military department will have to evaluate new developments and choose the most successful ones for further production and operation in the army.

Obviously, first Baikal will go into service with the Russian army. At the same time, it is not yet clear in which particular sample. Several BBMs have been developed on serial and advanced chassis, and all of them may be of interest to the army. It remains to wait for official statements and data on this subject. Then it is possible to launch a series of South African-Kazakhstani "Barysa" with Russian weapons. In the long term, the appearance of the Russian-Indian BMP with such weapons can be expected.

However, to obtain such results, it is necessary to complete the ongoing work. Only after all activities are completed, the AU-220M will be able to go into production and into service. And only then will the army or a foreign customer be able to get all the desired benefits associated with promising weapons.

    Well, and sho ?! How "folk wisdom" is wailing: if you suffer for a long time, something will work! They say about the 57-mm cannon of "high ballistics" ... then they say about the 57-mm low-impulse cannon of the "grenade launcher" type ...! As the matchmaker put it in "The Marriage of Balzaminov": that vodka, that cologne - everything with degrees! Yes But in order to figure out which projectile to stuff into the gun, one ruler for 57 mm will be needed! fellow And if by that time 57-mm "anti-aircraft nails" arrive in time for the "Shell", then we will use them too!

      Fundamental and substantial the difference between them is that the 57-mm low-pulse grenade launcher was ordered by the Ministry of Defense of the Russian Federation for military tests on a dozen samples; and the 57-mm high-ballistic automatic from Barricade-Uralvagonzavod no more than prototypes from which GBTU of the RF Ministry of Defense denies (although lobbyists can push through for the Parade).

      Well, the article itself simply informs us that the Uralvagonzavod is installing its DUMB on many basic chassis. But, in general, it does not contain at all any specifics on the real combat capabilities of the 57-mm high-ballistic assault rifle - and this is precisely the main thing.
      Well, we can state the fact of extreme desire of the Nizhny Tagil Uralvagonzavod do not miss out show "factory patriotism" (tm) and does not allow betting on the T-15 normal weapons in the form of a 100 mm gun; neither in the variants from the Tula KBP, nor in the variants of the Kurgan Special Design Bureau - although the combat module from the Dragun infantry fighting vehicle is straightforward ..

          Doesn't weight scare you? What about the price? And now the most important thing, will you take the space for the 125mm and 57 mm automatic loader? What about ammunition? I'm afraid even in a monstrous armature (T-15) THIS will not fit ..

          It's pointless.
          Both the 125-mm tank gun and the 57-mm clone S-60 are high-ballistic guns with a similar range of targets - primarily combat vehicles and targets with a pronounced noticeable vertical projection. At the same time, a 125-mm gun is 12 times more effective than a 57-mm gun - and penetration is much higher, and accuracy is worked out, and there is a powerful OFS.
          This is not to mention the great difficulties with the layout in a single block of two of these guns. Here is the case when size and energy matters.

        Well, what’s the difference in the technical plan ?, it’s personally violet to me, who ordered what and where is trying to put it, do you really need this? For what? How effective, because 23 mm, is a transition gauge. A 30 mm main, so laid, but where to stick 57mm? It is clear that if a simple infantryman ran with 57 mm of fluff, then generally cool, but ....?

        By the way, yes! The terminator is already unclear why it is needed, and even its wretched armament in the form of a 30 mm double-barreled shotgun makes the idea even worse. What does not suit a great option with a combat module BMP-3? A 100 mm gun and a 30 mm finishing machine solve all support tasks.

        Do you think this gun is bad?

        I don’t think he’s not good or bad. The main thing is what this "piece" is intended for and what it is used for. The 57 mm caliber itself was identified in the design bureau of V.G. Grabin as the optimal anti-tank
        At the same time, our accumulated experience allowed us to confidently tackle such a difficult task as determining the best caliber for a new powerful anti-tank gun. According to our calculations, the new anti-tank gun was supposed to penetrate 100 mm thick armor from a distance of 500 meters, and 90 mm thick armor from a distance of 1000 meters. (Weapon of victory. V.G.G)

        What was excellent in 1942-1955. in 2020, it’s no longer suitable as an anti-tank one, I don’t know how to use a field one with a low-explosive high-explosive shell. And as an anti-aircraft gun - against light drones is redundant, against helicopters - not long-range and quick-fire. The number of shots on the mobile platform is significantly inferior to the same 30 mm. If there is a sufficiently wide scope of this tool, then probably it will be quite good.
        PS I focus on sailors who have actually abandoned 57 mm.

        It is neither bad nor good. It’s just about anything for BMP - it has TTX unnecessary for BMP, and doesn’t have the necessary ones.
        Like an anti-aircraft gun - it may well be.
        But - the shot is terribly outdated. It is necessary to change the form factor, sleeve material, etc., etc.

        Not necessary .. This is a naval system, but there it is not needed due to the small caliber and scanty series as such .. So they try to attach it at least somewhere .. But on land there are more sane options, when designing the BMP-3, we considered this option but they refused because of low characteristics for all tasks ..

      It all started even earlier.
      First there was the 57-mm naval gun A-220, developed in the late 60s - early 70s. The fleet refused him - he already had an AK-176. In the late 90s CRI "Petrel" upgraded the gun in the A-220M and offered the fleet and border guards. The answer was traditionally negative, and the reason was traditional - the same AK-176.
      And then “Petrel” decided to try his luck with the army team. smile

    The Baikal example shows how weapons and infantry fighting vehicles are changing. Currently, such a BMP-3 with Baikal in the Dragon version is one of the best BMPs in the world. Its armament is slowly establishing a development trend for this class of infantry vehicles.

    Meanwhile, 25 years ago, in the mid-1990s, when the BWP-2000 with a 60mm OTO-Melara gun was developed in Poland ...

    all experts criticized the choice of weapons - and there were too few ammunition, too powerful for armored personnel carriers and infantry fighting vehicles, too weak for tanks and so on.

    This, of course, was not without BMP flaws, and Russian vehicles are at a much higher level, however, it shows a change in thinking about armament in this class of armored vehicles.

        This is just my opinion. In the version with Baikal, this BMP is definitely more balanced than the version with the original tower. The ramp is also a world standard solution.

          just the standard BO BMP-3 (as well as "Bakhcha") is more optimal and versatile in solving combat missions (there is a rapid-fire gun for lightly armored and unarmored vehicles, there is a fairly powerful OFS and TUR). 57 mm shell - neither fish nor meat.

            Let me start from the end
            Before the advent of Kurganets, the BMP-3 was the most armored of all domestic light armored vehicles.

            This is undoubtedly true, but I compared the BMP-3 not with a "penny" or BMP-2, and will call it the western level. Here, Russian BMPs are less armored, but can float.

            For weapons reasons, two systems are a complication when the 2A72 is quite known for inaccuracy, and a 100 mm gun will not destroy MBT from the forehead, from the side it will do the same 100mm and 57mm, while the latter will provide a high rate of fire or a larger stock of ammunition.

            The capabilities of 57 mm will increase significantly if new ammunition is introduced, and not just those that remember the S-60.

            also interesting on the other hand is the Epoch module LShO-57 and the Bulat missiles, the Kornet ATGM

            Huge selection of features!

              in the event that the gun is installed without devices for increasing the stiffness of the barrel (low accuracy is precisely this, in the increased vibrations of the barrel 2A72). On BMP-3 "thirty" is fixed rigidly to the barrel of the "weave".

              in the BC there is a TUR, as well as the ability to use ATGM "Konkurs-M" missiles with armor penetration up to 750 mm.
              For modern MBT, this, of course, is not enough to defeat the frontal projection. But how many modern MBT in the world? In order to destroy a modern tank with high probability, it is necessary to have either a gun with good ballistics with a caliber of 120-125 mm and BOPS, or an ATGM caliber of 152 mm (like Cornet). Or hit the roof.

              You won’t argue that the power of the 100 mm OFS cannot be compared with the 57 mm? Weaving is well suited for the destruction of manpower and fortifications of the enemy

                I am not going to argue with a higher efficiency of 100-mm OFS, because this is an indisputable fact, but ATGM "Konkurs-M" can be added to the "Baikal" module.

                There is such a concept in small arms (especially sniper), the so-called "free barrel". supporting or attaching the end of the barrel to an otherwise otherwise heating element does not necessarily affect accuracy. Whether this is possible with the 2A72 in the BMP - I don't know, but it is possible.

                Currently, most western infantry fighting vehicles can withstand Soviet / Russian 30mm strikes in the frontal projection. 57 mm net BMP-3 will have to use a 100 mm a small amount of ammunition

                  Without additional mounted armor sets - units of samples. With the appropriate weight and price. The vast majority are only with additional mounted armor sets. For protection requirements from 30mm, read STANAG. Distance - from 500m
                  Some armor-piercing shells for "Russian 30mm" foreign production are significantly superior to domestic "Kerner".

                  Here is the standard installation for 2A72.

                  As you can see, the gun barrel has an additional mount in the muzzle, providing accuracy and accuracy according to the statement of work. And the BMP-3 with 2A72 is fine.
                  All problems for 2A72 began when it was "taken out of the cradle" and put into the installation without this additional fulcrum (BTR-82). Accuracy and accuracy immediately flew. As a result, the rate of fire had to be reduced.
                  ... for more than a year, designers have worked to ensure an acceptable result: accuracy and accuracy should not be lower than that of 2A42 on the BMP-2. Without fulfilling this condition prescribed in the statement of work, the car was not taken into service. One machine was even made with a third fulcrum: a casing on top of the gun with a ring at the end in which the barrel walks.
                  But it didn’t help much either. The solution was found after watching ultra-fast shooting shooting.
                  Some time after the shot, the gun barrel takes its initial position, so the rate of fire was adjusted so that the next shot occurred at that moment. Yes, the maximum rate of fire became slightly lower than what is indicated in the tabular values ​​for 2A72, but sufficient to solve the same problems.

                    Either my spelling is incorrect, or there is a misunderstanding. Yes, I know what a “free trunk" is - the solution in the BMP-3 is exactly the opposite - there the trunk has support from both ends. And this is what I wrote in BMP-3, and not that it has a “free barrel”. I am writing with a translator, so this is probably a translation error

            My opinion is that for these purposes there is nothing better than the Bakhcha module, as it is now on the BMP-3. But with the addition - a grenade launcher like on "Berezhka", a couple of ATGMs just in case, and all this is based on a heavy and protected T-15.

    It is well known that the main reason for the emergence of DBKM "Baikal" was a kind of crisis in the field of light armored vehicles.

    The main reason for the appearance of the Baikal DBM was another refusal of the fleet and the FSB to install the 57-mm Burevestnik cannon on the ships, which the design bureau has been trying to push to the sailors and border guards since the 70s of the last century. smile The naval forces once again stated that they were completely satisfied with the AK-176, which even fits on the RCA, and they are not going to reduce the power of the projectile.
    And then the design bureau converted the gun into a land version and offered it to the army team.

    Both the 57 mm guns became obsolete before they were born - now guns using telescopic shots are in trend. Plus, for installation on the BMP / BTR, a low-pulse low-ballistic gun is required. From this pair of parameters, the required caliber of 76 mm and the ammunition of the calibrated OFS and the sub-caliber BS are obtained.

          The difference is very significant. If they taught physics at school, then everyone would understand for themselves. The cumulative projectile pierces the armor due to the cumulative effect, armor-piercing - due to kinetic energy. If a high speed COP is not needed, then a BR is simply necessary. A BPS fired from a low ballistic gun (which a priori has a low initial projectile velocity) is simply incapacitated. Everyone who says that it is possible to effectively shoot BPS from low-ballistic weapons is simply ridiculous, and, to put it mildly, very stupid people.

          The BC of the "land" 57-mm anti-aircraft gun S-60 included fragmentation-tracer and armor-piercing shells, and the BC of the AK-725 shipborne gun (also with a caliber of 57 mm) - only fragmentation tracer. The composition of the ammunition is determined by the tasks facing the artillery system. A tank cannot fight aircraft, and an anti-aircraft shell is unnecessary for it.
