The first show of the BMP-3 "Derivation" with the combat module AU-220M

107
Not so long ago it became known that the development of the new infantry combat vehicle BMP-3 with the combat module АУ-220М, which received the designation "Derivation", was completed. It was reported that the prototype of this armored vehicle will soon be shown at the international exhibition of weapons and equipment Russia Arms Expo 2015. Already on the first day of the exhibition, the project authors fulfilled their promise and presented a prototype of the updated BMP-3 with enhanced weapons.


From previously published materials, it was known that the “Derivation” project implies the removal of the original turret of the combat vehicle, instead of which a new remotely controlled combat module AU-220М with the original weapons is installed. In addition, there were fragmentary information about some other changes that accompany the installation of the new tower. Nevertheless, until recently all confirmed information about the project “Derivation” was limited only to the fact of the use of a new combat module.


General view of the upgraded BMP-3


Some new details of the new project became known just a couple of days ago, immediately after the opening of the Russia Arms Expo exhibition. Concern Tractor Plants presented a prototype of a modernized BMP-3, which everyone can now see. Through the efforts of the media and enthusiasts, a number of interesting photographic materials have become available to the public: everyone who is unable to attend the exhibition can see the new car.

As follows from the published data, during the “Derivation” project it was decided to slightly modify the basic infantry fighting vehicle. All the innovations implemented mainly concern the layout of the internal volumes of the hull and the placement of various units. In connection with the use of a new uninhabited combat module, it was necessary to rework the layout, as well as change the composition of the equipment of the machine.

In the base configuration, the BMP-3 has two places for paratroopers, located on the sides of the driver's seat. Next to them are the so-called. Autonomous machine gun installations. The machine of the project "Derivation" lost the front machine guns, and the places of paratroopers remained, but were "redeveloped." Now, the commander and gunner-operator of weapons must sit on the sides of the driver. Their jobs are equipped with a set of special equipment, with the help of which it is proposed to monitor and control weapons.

On the existing photos it is clear that the workplaces of the commander and the gunner are equipped with consoles with liquid crystal screens, control knobs, etc. hardware. Such equipment allows to carry out all operations for managing the combat module, to monitor the environment, etc. As an additional means of observation, periscopic devices at the hatches in the roof are preserved.


Close-up combat module


Two places for paratroopers, previously located near the driver, were transferred to the port side. The installation of a new combat module led to the release of a sufficiently large volume, which made it possible to place two chairs on the port side, where the turret basket was previously located.

Under the shoulder strap of the tower, on the floor of the habitable volume, mounts are located to support the combat module. The product AU-220М is mounted on the tower chase, and is also attached to a special cylindrical support mounted on the floor of the hull. Under the shoulder strap of the tower inside the habitable compartment there is a wide cylindrical cover of the inside of the combat module. He to some extent reduces the height of the troop compartment, but should not interfere with the landing and disembarking of fighters.


Left side of the module and one of the sights


The layout of the remaining volumes of the body remained the same. Behind the support of the combat module are several seats for the fighters. Behind their backs saved low-profile engine compartment. Above the engine compartment are two passes for landing through the stern. The power plant, transmission and other units of the modernized machine did not change.

The main innovation of the project "Derivation", attracting the greatest interest, is the new combat module AU-220M. This system was developed at the Petrel Research Institute, part of the Uralvagonzavod Corporation. The new combat module is proposed for installation on various combat vehicles, both promising and existing. A striking example of the latter possibility is the prototype combat vehicle, presented at the exhibition Russia Arms Expo.



The combat module AU-220M, intended for installation on armored vehicles, was first introduced at the beginning of this year. Then the sample system was demonstrated on a special rack. Now it came to installing the module on the full chassis of a combat vehicle. It was created taking into account the application, including on existing equipment, which led to the use of standard shoulder strap. As follows from the available data, the roof of the base BMP-3, which has become the prototype of the “Derivation” machine, has not undergone any changes.

The basis of the new module is a cylindrical platform with mounts for installation on the chase of the roof and the inner hull support. Part of this platform is located inside the body, part - outside. On the platform above the roof, the armament is fixed, as well as the observation and aiming systems.


The right side of the module AU-220M, in the foreground machine gun cover


The overall layout of the combat module installed on the “Derivation” machine fully repeats the layout of the previously demonstrated samples. On the platform there is a casing extending in the rear part, which accommodates the breech of the gun. On the sides of the hull smoke grenade launchers are provided. To the right of the main gun there is a swinging casing with a machine gun, which provides guidance for all cannon armament with the help of common mechanisms. To the right of the gun and on the roof of the casing are the sights of the commander and gunner. Also outside the central casing some other units are carried out.

The combat module AU-220M is of great interest because it can seriously affect the further development of armored vehicles and its weapons. During the development of this system, it was decided to return to the almost forgotten caliber 57 mm. Artillery systems of this caliber were actively used earlier, but over the past few decades they have almost completely become obsolete. The authors of the new project propose to recall such a caliber, since it gives certain advantages over existing tools.


Breech and gun bend sensor


The main weapon of the “Derivation” machine is a 57 mm rifled automatic gun. To protect against external influences, the barrel is equipped with a casing consisting of two modules. On the muzzle of the barrel is presumably programmer to work with controlled fuses. To improve the accuracy of fire and the collection of data on the state of the gun above the breech is a laser sensor for bending the barrel. The reflector of this device, in turn, is behind the muzzle device.

According to the developer, the X-NUMX-mm gun of the AU-57 module is capable of firing at a rate of up to 220 rounds per minute. The design of the combat module provides shooting in any direction with elevation angles from -120 ° to + 5 °. According to some sources, the BMP-60 “Derivation” main weapon’s ammunition consists of 3 projectiles. 200 unitary shots are ready for use and, apparently, are located in the automatic loading shop located in the support platform of the combat module.


Gun rifle device


The AU-220M system can use shells of various types, high-explosive fragmentation, armor-piercing, etc. It is also known about the work on the creation of a promising air explosive ordnance. At the expense of a programmable fuse, such a projectile should explode at a given point of the trajectory, hitting enemy manpower or equipment with the maximum possible number of fragments. Depending on the type of projectile used and the parameters of the gun pointing, shooting at a distance of up to 12 km is possible.

Auxiliary armament "Derivation" consists of one PKTM machine gun and two smoke grenade launchers. The machine gun is located in the swinging casing to the right of the gun and is pointed along with it. The ammunition of the machine gun in the form of 2000 cartridges in ribbons is located inside the combat module. On the sides of the combat module there are two four-barreled smoke grenade launchers.


One of the crew's workplaces with a combat module control panel.


The fire control system includes two sights for the commander and the gunner, a two-plane weapon stabilizer, a central computing system and a number of other equipment. Since the places of the commander and the gunner are taken out of the tower with weapons, observation of the terrain, search for targets and guidance of weapons is carried out using video systems. For processing and transmission of video signal as part of the equipment of the updated BMP-3 there is a corresponding block.

To date, the concern "Tractor Plants" and the Central Research Institute "Burevestnik" have built a prototype of the promising infantry fighting vehicle "Derivation". Information about the tests of this machine is not yet available, but there is reason to assume that during the inspections it will demonstrate all its positive qualities and prove the high potential of the new combat module.


View of the landing / combat compartment from the roof of the logistics


Shortly after the appearance of the first information about the combat module with the 57-mm cannon, the reasons for the development of the project began. The main reason for the emergence of the project lies in the need to increase firepower due to the increasing level of protection of armored vehicles. In recent decades, armored personnel carriers and infantry fighting vehicles "learned" to counter small-caliber artillery. Modern light and medium-class armored vehicles are able to withstand hitting projectiles of caliber up to 30 mm, but so far they cannot cope with more serious threats.

Thus, an increase in the caliber of the gun to 57 mm with a corresponding increase in muzzle energy and other important parameters allows for the effective defeat of the protection of existing and prospective armored vehicles. The use of 57-mm guns will improve the parameters of the destruction of armor, as well as provide a noticeable increase in effective firing range.


Car interior. In the center is the support of the combat module, in the background are the jobs of the commander and the gunner


As a result, the emergence of new combat vehicles with a combat module AU-220M or other similar systems, the situation on the battlefield should be seriously changed. One of the parties possessing such a technique will have significant advantages over the enemy. Similar benefits will continue until appropriate means of protection and similar weapons are available to other parties to the conflict. As a result, the implementation of new Russian projects can have a noticeable impact on the development of armored vehicles around the world.

At the moment, only one combat vehicle equipped with an AU-220M combat module with a 57 caliber mm gun is known. This is the prototype BMP-3 "Derivation", currently on display at the exhibition Russia Arms Expo 2015. In the near future there may be new types of equipment with similar weapons. In addition, it can be assumed that, over time, such armored vehicles will be put into service and will go into mass production. New weapons should lead to the emergence of serious advantages over potential adversaries, however, the timing of the start of its operation remains unknown. It remains only to wait for new messages on the progress of the program to create 57-mm guns and related equipment.

      This is essentially a concept. One of the possible directions of modernization. In my opinion it is very controversial. Lightly armored targets and 30 mm hit quite well and in terms of air targets it is more effective in my opinion. The lack of 100mm guns makes it impossible to conduct high-explosive and voluminously detonating ammunition, which reduces the effectiveness of combat with infantry. The lack of sane protection against hand grenade launchers negates the value of the places under the armor. In general, the machine turned out to be very narrowly specialized.
      In my opinion, it would be more interesting to put there a marine AK 630 or GSh 6-30 with a block of barrels) to reduce landing, but increase BC. In addition, use mounted DZ. To combat armored vehicles-ATGM.

        All modern BMPs and armored personnel carriers of NATO are developed with a key requirement - the ability to withstand shelling of 30-mm Soviet automatic guns in the forehead. Old upgraded to this level of armor protection.

        Have you missed anything in life? Well, the fact that before this reservation back in Soviet times to 30mm 100mm was pandoned with the ability to shoot ATGM and helicopters in particular! ?? laughing Well, and why the heck are these two steps to the left, two steps to the right, a step near the pie and two back?

          And on BMPs also shoot ATGM?
          And what is the percentage of helicopter damage by an anti-tank missile?
          For reference: 57 mm S-60 is an anti-aircraft gun. Ammunition includes shells with remote detonation, which makes it possible to fire barrage at air targets. Attach ATGM Cornet is not difficult. So, if a 100 mm gun is suitable for a light vehicle, it is only for a fire support machine, although this role is either played by main battle tanks, or there is already a SPRUT with a 125 mm gun in production.

            Attaching ATGMs and others significantly increases the cost and somewhat makes the entire structure heavier. And this is a massive machine to combat lightly armored ground and low-speed air targets.

      Edward, you are absolutely right, BUT! What will this gun fight with? Lightly armored targets are also hit by a more universal 30mm. Heavily armored 57 will not hit. To shoot from this fool on drones?)) So there the shell is larger than this drone. And the rate of fire is less. A very specific and highly specialized tool in my opinion. But the experience in designing such systems is sure to come in handy. This cannon has a road to the fleet. The fight against armored vehicles, etc.)

        Why not hit? 45 mm BPS penetrates 150 mm at a range of 1500 m. I think that the BPS 57 mm will penetrate more. And it turns out that the tank in the ass and in the side is likely to hit. And if in the forehead it will incapacitate - for example, falling into a caterpillar or under a tower. The fact that there is no ATGM on this module is a temporary problem.

        The shell there weighs within 2 kg. Plus, this gun was massively used in the army as an anti-aircraft gun. In principle, a similar approach was taken by the Swedes, with their CV-90 infantry fighting vehicle, where they put a 40 mm L-70 Beafors gun.

      The gun is automatic, only its rate of fire does not exceed 120 rounds per minute, this is due to the shells used. By the way, these shells can be fired from an anti-tank gun ZIS-2, 1943

    Looking at the photo, the question arises: where is the ammunition load of 200 shells for the 57 mm gun? The volume of the uninhabited tower to store this amount is clearly insufficient. I dare to assume that the ammunition is located around the turret, but in the instance shown in the photo, the ammunition with the feed mechanism is dismantled.

      in a tower of 80 shots from 200 declared. And the machine gun 1000 out of 2000 declared. The rest, apparently, are in the fighting compartment. As a result, manual reloading under enemy fire is quite likely, yeah.
      And what have they achieved?

      Is it not clear that this 57mm shot is oversized for BMP? Here, all the "partners" unanimously develop telescopic ammunition, we are the only ones who play bullshit.

    The main disadvantage of the new “Derivation” is the absence of ATGMs. This infantry fighting vehicle cannot fight tanks and in this form our infantry is not needed. But the direction chosen is the right one. It would be more correct to install a combat module with 57 mm AU on the "Dragoon" and additionally put 2x2 anti-tank missile launchers of the Berezhka type.

    I agree, there is not enough 4 ATGM. There will be no problems with the absence of a 100mm cannon, the power of the 57mm HE projectile is decent, add a line of 3-4 shells here and the effect will be very good. The prospect is remote detonation. This increases efficiency at times. The armor-piercing component compared to the 30 and 100mm gun will be 2 times higher. And this is an excellent breaking through the walls in urban environments. But to deal with aircraft, you need equipment and radar in the car, but it is not.

      Yes, what is worse? Bradley will bring down better, and the tanks, too, since the 100-mm ATGM is very weak. ATGM should be separate. 100-mm has one plus-banging on shelters, well, in urban conditions, for example. And about the fragmentation effect. It's better mortar. Than one 100mm or a queue from 3 - 57mm.

      Dear avt, I appreciate your sense of humor. But my experience as a computer warrior says that a unit with a high density of fire (not as sure as the sea, we don’t have to shoot down anti-ship missiles) and ammunition like a 30 mm gun would be quite good with infantry support in urban combat when it is necessary to crush it with fire density when posting columns, etc. But this is, as you noticed on the computer))). What is being done there in your reality, alas, I do not know)

        Here you can take the weight of a second volley and calculate the return. How not to integrate - the same shell, the same rate of fire.

    A 57mm assault rifle is certainly a good thing, but to destroy tanks the Cornets will be more efficient. Besides, isn't the BMP fleet in the Russian army too colorful? BMP-2 and BMP-3 in various modifications and upgrades, Kurganets, T-15 Armata! But in fact at the moment there are somewhere around 1000 BMP-1s, 3000pcs BMP-2s that have long been outdated and only 500 pcs relative to modern BMP-3s (which began to be produced in the late 80s and were developed in the late 70s!) And if tomorrow the war and will the enemy attack? Is it time to decide and issue in a large series of "what you need" BMP ?!

    I think the 57mm gun will be better than the 100mm gun. Compared with a 100mm cannon, here we have a higher rate of fire and a larger transportable ammunition. The issue of tank destruction can be addressed to ATGMs, which can be used to equip a tower. It is good that in the airborne squad 7 people are accommodated (squad).
    Of the minuses, I would pay attention to the complex shape of the body at the installation sites of the Kursk machine guns. I recall the experience of operating IS-3 tanks, where a pike nose eventually gave metal fatigue and cracks appeared on the armor. Causes some concerns sticking power supply to the machine gun. Not even an hour and a stray bullet or a splinter will break this thread. Well, even though you kill me, I do not like the landing of the troops up. Where does this lead? Under the bullets?

      As for me - both Derivation and Bakhcha are excellent modules and should be. It’s just that Derivation is being worked out for placement on TBMP T-15. And Bahcha will serve on the BMP-3. Although nothing prevents putting her on Kurganets for example.

    knowledgeable people tell me why the tanks use a “cheburashka” to control the turret (gun) - it seems terribly inconvenient to me, but in this BMP-3 they finally put a joystick - it seems to me very convenient and more functional!

    If during the tests of the guns the ATGM was not hung on the tower, this does not mean that they will not be on the serial machine. Our designer and the military will not get to this.

    But in general, I’m here looking a lot literally mesmerized by a large caliber THINWALL 100-mm gun. We already had the LIGHT 73mm gun on the BMP-1, and the 30-mm was more effective. And also someone then considered it a step back.
    And tell me how many 100-mm high-explosive shells on the BMP-3 and what is their initial speed? What about the rate of fire? A sighting range?
    Everything will fall into place.

    In Dangoy modification, several things are happy at once:
    1) the ammunition with 100mm high-explosive fragmentation shells and charges to them were removed from the landing. Already good. In case of penetration, the crew and the landing force will not detonate at once.
    2) We got rid of the front seats of the landing which, as they say is not to God, a candle is not a damn poker.
    3) In the landing there was a place for transportation of all kinds of utilities.
    limitations:
    1) the inherent three inconvenient access to the landing (although the inconvenience is very moderate and, in general, tolerable)
    2) the reduced height of the landing compartment, I think, will not add comfort.

    The BMD-4 gun, in fact, is a converted pipe from a mortar). Fires rockets. An active projectile will tear this barrel to pieces. The cannon with a caliber of 57 mm, a classic gun with a thick barrel that can withstand a projectile with a high initial velocity.

    The shown Swedish 40 graph paper impresses with its capabilities. And it sews more than 100 mm with sub-calibers, and it is very distinctly programmable ammunition for infantry and helicopters. What will 57 mm be capable of? Both in infantry and in armored vehicles - at least twice as strong. Maybe such a powerful ATGM gun is not really needed. This is the reincarnation of the 57-millimeter anti-aircraft guns. Considering that such equipment will be used in large quantities (3 vehicles in a platoon), this is a sea of ​​high-power fire, both in defense and in offensive. At least an interesting novelty. Which will make potential "partners" scratch their turnips. Yes, the logistics will be complicated, but ... I imagine a combined anti-tank ambush of BMP-3 and 57-millimeters. BMP-3 ATGM deploy enemy tanks on themselves, and at this time, 57 millimeters on the flank, in minutes ...

    100mm is too large a caliber against infantry and lightly armored targets, 30mm is too small. 57mm, in my opinion, is the golden mean.

    "Derivation - lateral deviation of artillery shells from the target due to the fact that when they exit the rifled vent of the gun they rotate during flight"

    Whatever you say - our inventors love to get angry. What they had in mind when they gave such a name, what guided them - is generally incomprehensible. It can be assumed that, by analogy with the derivation of a bullet / projectile, this machine leaves the BMP 1-2-3 line with a classic turret.
    As for what they will call in the army, yes, as before, “Beha” and further by numbering ..
