Description

The invention relates to the field of weapons and military equipment, in particular to weapon systems (KB) of combat vehicles such as infantry fighting vehicles, tanks, armored personnel carriers, armored personnel carriers, etc.

The BMP-2 infantry fighting vehicle is known, the weapon system of which consists of a coaxial small-caliber automatic gun and a 7.62-mm machine gun, a launcher with anti-tank guided missiles, and a grenade launcher stabilized in two planes and a fire control system including day-night gunner’s sight, the head mirror of which is mechanically connected to the gun, the commander’s day sight, the head prism of which is mechanically connected to the gun, the day sight of a guided projectile mechanically connected to the take-off oh launcher for antitank guided missiles (PTUR) mounted on the tower, and stabilizer / 1. BMP-2 infantry fighting vehicle. Technical description and instruction manual. Part 1, 2. Armored vehicles. Ed. Potpourri, Minsk, 2000, pp. 180-184 /.

The main disadvantages of KB BMP-2 include the following:

- low firing accuracy on the move from the gun, since the sights rigidly connected with it are stabilized in space with an accuracy of stabilization of the power stabilizer of the weapon (dependent stabilization),

- vulnerability PU ATGM from bullets, fragments and blast waves,

- low efficiency of destruction of enemy manpower due to the low fragmentation efficiency of the small-caliber projectile, as well as due to the persistent trajectory of the projectile,

- low firing accuracy of the first stage and a large amount of time spent on firing the first stage, due to the lack of external information sensors, a laser range finder, roll sensors, the carrier’s own speed and calculations and development of firing corrections by the operator himself,

- the ability to hit tanks of the second generation with ATGMs only during the day, aiming at the same time with an automatic gun at night can be carried out at ranges up to 800 m, while most modern tanks and infantry fighting vehicles are equipped with thermal imagers with a range of at least 2000-2500 m,

- the impossibility of firing on the move guided missile (ATGM "Competition" with a wired communication line),

- the need for the charging launcher to get out of armor protection.

The BMP-3 infantry fighting vehicle is known, the weapons complex of which contains an artillery gun installed in the combat compartment — an ATGM launcher, an automatic small-caliber gun and machine gun, as well as an automated fire control system (LMS) located on the BM as part of a series-connected optical sight a gunner electrically connected with a weapon, a ballistic computer (BV) with a system of input information sensors, including a laser rangefinder, as well as an arms stabilizer / 2. Armored vehicles. Ed. Potpourri, Minsk, 2000, pp. 185-190 /.

The disadvantages of the BMP-3 weapon system, identified during operation, are the following: the insecurity of firing a guided missile at night, limited search capabilities from the commander’s position, due to the lack of a modern commander’s sight, low accuracy of the gunner’s aiming, especially in conditions of stressful situations arising in a combat situation, as well as in the presence of mechanical disturbances at his workplace.

The objective of the invention is to increase firing efficiency by increasing firing accuracy, speed due to, first of all, improving the fire control system (LMS), as well as expanding the conditions for combat use: ensuring all-day availability (the possibility of conducting combat operations day and night), firing from the place and on the move, expanding the range of ammunition used and the operating modes of the complex.

The problem is solved in that in the well-known armament complex of a combat vehicle, which contains an artillery gun installed in the combat compartment — an ATGM launcher, an automatic small-caliber cannon and a machine gun, as well as an automated fire control system (LMS) located on the BM as part of a series-connected an optical sight of the gunner (PN), electrically connected to the weapon, a ballistic computer (BV) with a system of input information sensors, including a laser range finder, as well as a hundred weapons armament, characterized in that the laser rangefinder is made high-frequency and installed in the optical thermal imaging PN, in addition to the control system, a panoramic television sight of the commander (PKP) is introduced, electrically connected to the weapon, with a laser high-frequency range finder and a tap from the thermal imaging channel PN, a tele-thermal tracking machine objects (ASOTT), control unit (BU), the operator-gunner’s console (PO) and the commander’s console (PC), with the first inputs and first outputs of the software, ASOTT, BU, weapon stabilizer, ballis of a computer, PN and PKP, as well as input information sensors are connected to a digital communication channel, the second inputs of PN and PKP, ASOTT are connected respectively to the second and fourth outputs of the control unit, the second and third inputs of which are connected respectively to the third and second outputs of the weapon stabilizer, and the fourth input of the control unit is with the second output of ASOTT, the second input of the weapon stabilizer is connected to the second output of the military unit, its third input is with the third output of the software, the fourth and fifth inputs of it are with the second outputs of the PN and the control panel, respectively, the PC and the software are mutually edineny their inputs and outputs, and Mo and the control panel are independent stabilization biplanar head mirror.

The problem is also solved by the fact that the laser high-frequency range finder PN is aligned on a common base and combined by a common block of the head mirror PN with a stabilization and guidance system and a thermal imaging channel.

The problem is also solved by the fact that the PN is configured to provide a deviation of the angles of inclination of the line of sight relative to the carrier up to 30 ° in the vertical plane, up to ± 10 ° in the horizontal plane, the angular velocity of the line of sight up to 20 deg / s.

The problem is also solved by the fact that the high-frequency laser rangefinder of the control panel is aligned on a common basis and combined by a common control panel head mirror block with a stabilization and guidance system, as well as with a television channel.

The problem is also solved by the fact that the control panel is configured to provide deviation of pumping angles relative to the carrier up to 60 ° in the vertical plane, circular rotation of 360 × n in the horizontal plane, angular velocity of the line of sight up to 20 deg / s.

Armored vehicles for a long time were characterized by unsatisfactory visibility and search capabilities of the crews. This adversely affected the survivability of military vehicles during combat operations in poorly visible terrain. Infantry with light portable ATGMs or RPGs affects such armored vehicles, shelling it from all directions into vulnerable areas. Losses of armored vehicles in local conflicts confirm this. In addition, for lightly armored vehicles armed with small-caliber automatic guns with an effective firing range of 1,500-2,000 m, there was no need to equip it with developed automated LMS. Fighting vehicles, for example BMP-2, which had mounted guided weapons, fired ATGMs only from a place.

At the same time, tanks armed with cannons of caliber 100-125 mm fired at ranges of up to 2.5-3.0 km from the spot and on the move. This was facilitated by equipping them with weapon stabilizers, laser rangefinders, ballistic computers with sensors for firing conditions. And the main sights of the gunner and commander had independent stabilization of the field of view, which improved the conditions for searching for targets by the crews during the movement of the tank, and increased the accuracy of aiming.

In the field of SLA for lightly armored vehicles, a quantum leap is associated with the adoption of the BMP-3, equipped with a 100-mm gun, 30-mm gun and guided weapons with a missile fired from the barrel of the gun. In order to increase firing accuracy, combat vehicles were equipped with SLAs with parameters no worse than tank SLAs / 3 /. At the same time, parameters introduced into the ballistic computer, such as machine speed and heading angle, target angular velocity in the horizontal channel, machine roll, were automatically received from the sensors. For slowly changing parameters: temperature of air and charge, atmospheric pressure, deviation of the initial speed - manual entry was provided. Thus, there is a convergence of the lines of development of the SLA of tanks and lightly armored vehicles, in particular BMP.

However, the BMP-3 type of existing means of armored vehicles that are part of the computing system include analog ballistic computers (adopted in the 80s) (in BMP-3 - 1V539) with a simplified firing algorithm. In this regard, the composition of the sensors of the external shooting conditions is incomplete, the data input from them is manual, from the BV panel (pressure, air temperature and charge), their accuracy and dynamic characteristics require improvement. In particular, the laser rangefinder has a low range measurement frequency (f = 0.5 Hz).

In addition, the gunner’s sight provides limited angles of pumping of the line of sight: in the vertical plane from minus 15 ° to plus 30 °, in the horizontal plane ± 7.5 °, and the speed of pointing the line of sight does not exceed 5-7 ° in the vertical and 5- 9 ° - in the horizontal plane / 4, p. 9 /. All of the above does not allow for effective shooting at high-speed, in particular, air targets / 3 /.

Expanding the nomenclature (composition) of BM armament (100-mm gun, 30-mm automatic gun (AP), 7.62 mm machine gun), types of ammunition (in the gun - two shots: 3UOF32, 3UOF70, in the AP - high-explosive fragmentation ( fragmentation tracer), armor-piercing, armor-piercing-sub-caliber 30-mm shells) allows us to significantly expand the functions of the BM armament complex and the conditions for its combat use, the types of targets hit. In technical proposals and then in technical tasks, new combat missions appear - effective shooting at air targets, shooting from closed positions.

This leads to the need to create, as in promising tanks, combined gunner and commander instruments for detecting targets, evaluating its movement parameters, tracking when firing unguided munitions, and controlling a missile in all conditions of combat use, when working from place and on the move.

Figure 1 presents the appearance of the sight of the gunner.

Figure 2 presents the appearance of the panoramic sight of the commander.

Figure 3 presents as an example the projection of the firing zone of a 30-mm gun at an air target flying at a speed of 200 m / s at parameter p = 300 m, height H = 150 m when using a gunner’s sight (PN) (fig. 3b) and the sight of the commander (PKP) (figv). For comparison, shown are the firing zones with the gunner’s sight 1K13-2 standing on the BMP-3 infantry fighting vehicle (Fig. 3a).

Figure 4 shows the miss obtained by firing at an aerial target of a 30-mm gun using a 1K13-2 sight.

Fig. 8 is a diagram illustrating an increase in firing efficiency when using the proposed weapon system when firing at an air target when flying over a target at parameter p and height H, respectively: p = H = 200 m, p = H = 500 m, p = H = 1000 m for combat vehicles of the modernized BMP-2M and BMD-4 type when using the gunner’s sight (PN) and the commander’s sight (PC).

On Fig presents the appearance of the control unit (CU).

On Fig a-c presents the appearance, respectively, of the control unit of the weapon stabilizer, power amplifiers UM-400 and UM-1200, electric motors VD-400 and VD-1200.

On Fig presents a functional diagram of the control system of the BM armament system: 1 - ballistic computer (BV), 2 - weapons stabilizer, 3 - control unit (BU), 4 - telemetry imaging tracking machine (ASOTT), 5 - gunner’s sight (PN) 6 - commander’s panoramic sight (PKP), 7 — commander’s console (PC), 8 — operator’s console, 9 — LMS sensors.

The commander’s television panoramic sight (PKP) with a high-precision system for stabilizing the field of view (standard deviation of stabilization errors 0.05-0.06 mrad / State test reports / versus 0.15 mrad in BMP-3/4 /), with a frequency laser rangefinder (with a frequency up to 5 Hz versus 0.5 Hz in the BMP-3) and a television guidance channel was developed GUP "KBP" to equip the BMP and tanks / 6 /.

The sight provides the commander with an all-round visibility, independent of the gunner’s sight, target designation of the gunner and effective firing of all types of unguided shells in duplication mode. Large up to 60 ° angles of pumping of the line of sight in the vertical plane, increased to 20 deg / s, its angular velocities in the "air" mode, high-frequency ranging allow shooting at air targets.

The control panel includes:

a) the guidance and stabilization system of the sight of the commander of the panoramic SNA PKP (SNA), including:

1) head mirror block (BGZ);

2) control unit (BU);

b) module television rangefinder (MTD);

c) video viewing device VSU-12 (APU).

Figure 2 presents the appearance of the panoramic sight of the commander.

The gunner’s optical and thermal imaging sight with a laser high-frequency (up to 5 Hz) range finder allows firing with all types of ammunition not only at any time of the day, but also in conditions of limited visibility (haze, smoke interference) due to the use of thermal imaging (λ = 8-12 μm ) channel. Combat work can be carried out by the gunner through the sighting channel and the video viewing device (APU). The commander can also use the thermal imaging channel at night through his APU. The angular speeds of the line of sight increased to 20 degrees per second allow firing at air targets and from the gunner’s position. Like the commander’s sight above, the gunner’s sight was developed by the KBP KBP for equipping infantry fighting vehicles and tanks / 6 /.

Figure 1 presents the appearance of the sight of the gunner.

The status and directions of similar developments on the sights of the commander and gunner are presented in the relevant literature, for example / 8 /.

Figure 3 presents, as an example, the firing zone of a 30-mm gun against an air target flying at a speed of 200 m / s, using a gunner’s sight (PN) and a commander’s sight (PKP). For comparison, the shooting zones are shown with the gunner’s previous sight 1K13-2, standing on the BMP-3.

As follows from the figure, the firing zones are significantly expanded, especially in the most effective near zone.

However, and this is the most important, thanks to the improvement of the SU BM, the accuracy of shooting has significantly increased. For example, figure 4 shows the miss obtained by firing at an aerial target of a 30-mm gun using a 1K13-2 sight, and FIGS. 5-7 show random and systematic errors resulting from the output of a computer system: errors of the aiming and navigation system ( Fig. 5), errors of meteorological ballistic training (Fig. 6), systematic errors (Fig. 7) when firing a 30-mm BMD-4 gun with advanced FCS. On Fig, as an example, are diagrams illustrating the effectiveness of firing at an air target with a new SLA. For comparison, the previous levels provided when shooting with a foreshortened scope are given.

The tele-thermal imaging tracking machine (ASOTT) provides high-precision guidance of the aiming mark on the target in real combat conditions. This is especially important when firing a guided missile, since the total missile guidance error by almost 90% consists of the error of aiming the aiming mark on the target. The gunner directs the reticle to the target, switches to its automatic tracking mode, then starts and is released. In other words, the principle of "shot and forget." The probability of a missile hitting a target becomes technically guaranteed, since a person is excluded from the guidance loop. This quality of the LMS, as well as the automation of shot preparation, reduces the load on the operator.

Automatic tracking of targets provides a significant increase in accuracy with unguided 100-mm and 30-mm shells, as well as 100-125-mm tank shells, especially when shooting at moving targets and in motion at high speed. According to the results of processing the GI data, the errors of stabilization of the line of sight in the automatic tracking mode are 1.5-2.5 times lower than with manual tracking, and the bandwidth of the spectral density is about two times narrower. And, perhaps the most important thing - in stressful situations of a combat situation, the stability of such tracking is much higher, the tracking failure is less likely in the conditions of a temporary (up to 5 seconds) interruption of the target signal (due to the presence of an inertial tracking mode).

ASOTT is an electronic unit based on a microprocessor and is designed to automatically accompany the line of sight of a television (PKP) or thermal imaging (TPV module PN) sight at a target set by the gunner or commander. Appearance ASOTT shown in Fig.9.

Gunner’s and commander’s sights, automatic target tracking systems similar to ASOTT described above are known from relevant literature, for example, from foreign sources - the TIS’s main gun’s sight M1 Abrams, GPTTS’s main gunner’s sight, IBAS BMP M2A3 and M2A4 Bredley / 8- sighting and sighting system 12 /, domestic - sight type "Sozh-M", "Spring-K" on the modernized BMP-3 Kurgan Machine Plant, in the sighting systems of anti-aircraft missile-gun systems.

The 1V539M ballistic computer is implemented as a reprogrammable processor, to the inputs of which the information from the sensors is transmitted in analog and (or) discrete form through a digital communication channel, through which the ballistic computer is also interconnected with other subsystems of the BM armament complex, in particular with newly introduced components control system (SU) BM control unit (BU), the operator’s console (ON), the commander’s console (PC).

The BV 1V539M is used as a ballistic computer in the armament complex; it is designed to collect information from sensors, process it, and calculate aiming angles and lateral lead when firing from an automatic cannon and guns - launcher, as well as adjust and control the control system during operation. When firing URs, the BV also solves the problems of developing constant aiming angles (when firing with and without excess) and anticipating or ensuring the shooting of the URs in the control field.

Unlike the 1V539 ballistic computer, which is part of the BMP-3 SUO, the 1V539M digital ballistic module has a greater circuitry potential and, therefore, creates the prerequisites for the implementation of a full firing algorithm, which can significantly expand the range of shooting factors taken into account.

For these purposes, a universal firing algorithm has been developed for promising means of armored vehicles, which, having ease of implementation, continuity of development, allows to realize the required accuracy of calculations based on the accuracy of the input information currently provided. Moreover, universality is understood in a broad sense: armament carriers (BM), types of targets and types of ammunition. Continuity of development consists both in the possibility of building up the amendments to be taken into account, if necessary, and in the use of information with already existing sensor equipment in the BM. New technical solutions used in the algorithm are patented.

Figure 10 presents the ballistic computer.

The commander’s console (PC), together with the operator’s console (ON), is designed to automate the loading of 100 mm rounds, load and unload OPU and AP, select the type of ammunition from the commander’s place and indicate the type of ammunition, indicate the remaining 30 mm and 100 mm ammunition .

PC and software are microprocessor-based electronic units that are interconnected with other units using a cable network.

In Fig.11 a and b presents the control panel of the remote commander (PC) and the operator (software).

The control unit is an electronic unit implemented on the element base of the controller and designed for / 4 /:

- switching video signals of the gunner’s and commander’s sights in order to ensure auto tracking from the gunner’s and commander’s workplaces;

- the implementation of information exchange between the components of the OMS;

- formation of service information on the APU of the gunner and commander (against the background of the observed image of the area);

- switching control signals and command formation when firing at unobservable targets ("VTSU" mode).

On Fig presents the appearance of the control unit.

The weapon stabilizer is designed to stabilize and direct the weapons of the complex when firing all types of ammunition from a place, on the move and afloat, together with the sights of the gunner and commander. The weapons stabilizer has eight operating modes: 1) “gunner’s gun”, 2) “gunner’s gun”, 3) “gunner’s semiautomatic gun”, 5) “gunner’s semiautomatic gun”, 6) “overview”, 7) " target designation ", 8)" tracking "instead of the previous five.

The stabilizer control unit (BUS) in the inventive weapon system, designed to summarize, convert and amplify control signals for vertical and horizontal guidance drives, as well as switch electrical circuits in order to provide different modes of operation of the stabilizer and FCS, is made in the form of an electronic device based on a mini-computer / 13 /, which creates the prerequisites for increasing its speed.

This is also facilitated by the transition to a direct current electric motor with collector electronic switching (instead of brushing), while the maximum number of engine revolutions increases from 3000 to 6000 rpm. As a result, the limiting angular velocity of weapon guidance increases from 35 (BMP-3/4 /) to 60 ° / s, and the stabilizer passband - from 2-3 Hz to 50-60 Hz.

Analysis of the known weapon systems of military vehicles does not allow us to identify in them a set of features that distinguish the claimed solution from the prototype.

To confirm the technical feasibility, the following is an example of the functioning of the inventive system - a weapon system of a combat vehicle.

The main mode of operation of the BMD-4 when firing unguided weapons is the "Automatic" mode: the sub-modes "Avt-N" (from the gunner's seat) and "Avt-K" (from the commander's place). In this mode, for example, from the gunner’s position, search, detection, target identification, tracking with distance measurement to the target are carried out day and night.

Target tracking is carried out by pointing the mirror of the gunner’s sight (commander’s sight) vertically and horizontally with the PUN (PUK) handles in manual mode or according to the commands generated by ASOTT in the automatic target tracking mode.

The signal from the position sensors of the mirror of the gunner’s sight (or the commander’s sight) vertically in accordance with the block diagram is supplied to the weapon stabilizer, where it is compared with the signal from the gun position sensor, which is mechanically connected with the axis of rotation of the weapon block. The error signal is amplified and fed into the vertical guidance drive, which leads to the rotation of the weapon in the direction of reducing the mismatch. When deviating from the stabilized mirror position of the gunner’s sight (commander’s sight) horizontally, an error signal occurs which is removed from the position sensor of the mirror of the gunner’s sight (commander’s sight) horizontally, amplified and fed to the horizontal guidance drive, which leads to a rotation of the tower to reduce the mismatch .

In accordance with the detected target on the remote commander (PC) set the desired type of ammunition. For example, in BMD-4 this is done by pressing the “BP” button on the gunner’s control panel (PUN) or the “BP selection” button on the commander’s remote control (PC) (until the corresponding indication appears on the software (8), PC (7) indicators, in the field of view of the gunner’s sight (5) or on the screens of the gunner’s video viewing device (APU-N) or the video observation device of the commander (AFU-K) of the corresponding indication of the type of ammunition being set, see Fig. 14. Logical signal "+ 27v", for example, the “BP” button is fed to the input of the operator’s console (software (8)). sits on a ring from among the loaded.

For example, if it is necessary to fire an automatic 30 mm gun when installing the types "O30" (high-explosive fragmentation shell), "B30" (armor-piercing tracer), "P30" (sub-caliber), after 1 s, a command to turn on is issued from the software to the automation unit appropriate supply (lower for "O30", upper for "B30" and "P30") of the AP power supply system.

The code of the established type of ammunition is transmitted via the RS-485 digital exchange channel at the request of the ballistic computer (BV (1)) from software (8) to BV (1), which, in turn, transfers it to the gunner’s sight (5), BU ( 3) and ASOTT (4).

The indication of the established type of ammunition is made on the indicators PO (8), PC (7), in the field of view of the gunner’s sight (5) and on the screens of the VSU-N, VSU-K.

Next, the range is measured by the gunner or commander. To do this, with the handles of the gunner’s control panel (PUN) or commander (PUK), respectively, the top of the aiming mark of the gunner’s sight (commander) is aimed at the target and the “D” button on the left PUN (PUK) handle is pressed.

In this case, the signal from the “D” button PUN (PUK) enters the control unit, where a sign is set of who is measuring the range, is there a measurement at all, and transmits it to the BV.

When measuring a gunner’s range, the BV issues RS-485 channels to the gunner’s sight for range measurement.

During normal operation of the RS-485 channel, the range finder of the gunner’s sight performs a range measurement cycle and displays it. After 0.7 s, the BV sends a command to request a measured range and receives a range code from the gunner’s sight.

After releasing the "D" button on the PUN, the BV sends a command to the gunner’s sight to turn on the indication of the range transmitted from itself, as well as the range code and the type of ammunition.

Similarly, ranging from PUKa is carried out.

The types of information transmitted for various LMS devices are shown in table 1.

Table 1 Digital Channel Operation Subscriber Transmitted (received information) Mon Accepts:
- control commands (range measurement, "control" mode, indication from a ballistic computer);
- indication codes.

- established range code.
Transmits:
- measured range. Weapon stabilizer Accepts the type of ammunition.
Transmits the command "TSU". Air temperature sensor Transmits:
- air temperature code. Charge temperature sensor Transmits:
- charge temperature code.

During operation, the BMS BW (1) polls the sensors and generates current corrections to the aiming and lead angles, which are then automatically worked out by the weapon stabilizer (2) in accordance with the selected type of ammunition, measured by the range to the target, speed and direction of movement of the machine, own speed of the machine , heading angle to the target, own roll and trim of the machine, data constantly coming from sensors of external conditions: longitudinal and transverse components of wind speed, air temperature, temperature shot rounds.

The stabilizer (2) in the considered modes “Avt-N” (from the gunner’s place) and “Avt-K” (from the commander’s place) guides the aiming line of the gunner’s sight (5) (commander’s sight (6)) according to the control action from the control panel gunner (commander), tracking weapons behind the line of sight (according to the sensors of the sight), taking into account the amendments issued by the BV (1).

For these purposes, the stabilizer control unit (2) performs the summation, conversion, and amplification of the control signals of the vertical and horizontal guidance drives, before that, after switching the electrical circuits in advance, to ensure the given operating mode of the stabilizer and the control system.

In the power amplifier UM-400, the control signal of the valve motor along the vertical channel is amplified by power, similarly - along the horizontal channel - UM-1200.

VD-400, VD-1200 valve motors are the executive motors of the vertical guidance drive (lifting mechanism) and horizontal guidance drive (rotary mechanism), respectively.

13 a-c, respectively, represent a weapon stabilizer control unit, UM-400 and UM-1200 power amplifiers, VD-400 and VD-1200 electric motors.

Compared with existing analogues, the inventive weapon system provides a significant increase in firing efficiency by 3-7 times depending on the conditions of combat use, and when firing, in particular, on an air target, by tens of times, see Fig. 8/3 /. This is achieved due to the following qualities of its subsystems.

The armament complex has an all-day LMS providing accurate firing from place and on the move, day and night, both guided and uncontrolled weapons.

High-precision stabilization of the field of view of the gunner and the panoramic sight of the commander provides good observation conditions when the vehicle is moving in day and night conditions. In addition, the commander’s sight provides a circular search for targets, independent of the position of the line of sight of the gunner’s sight. This increases the search and detection capabilities, which is especially important when fighting in poorly visible terrain.

An automatic target tracking system that excludes the gunner from the missile guidance loop provides a high, technically guaranteed probability of a missile hitting a target in stressful combat conditions. In addition, the target tracking machine provides an increase in the range of accurate firing of unguided projectiles at ground and air targets.

Digital SLA creates the prerequisites for the integration of a combat vehicle into the unit’s control systems.

The digital weapon stabilizer allows you to realize increased weapon guidance speeds with high accuracy.

The inventive armament complex in the form of a unified fighting compartment passed state tests and was adopted by the Decree of the Government of the Russian Federation No. 884 of December 31, 2004 "On the adoption of the BMD-4 airborne combat vehicle with the B8Y01 unified fighting compartment for light weight vehicles for the armed forces of the Russian Federation 3UBK23-3 mass and shot categories with 9M117M1-3 guided missile (code “Bahcha-U”). ” Currently, mass production of BWs and equipping them with BMD-4 airborne combat vehicles for the Russian Airborne Forces are underway.
