Complexes of active protection of the Arena family

Of great interest are the so-called active protection systems (KAZ) for armored vehicles. This equipment is intended for the timely detection and destruction of enemy antitank weapons flying up to a combat vehicle. A set of active protection means independently monitor the surrounding space and, if necessary, performs the so-called shooting. protective ammunition. In recent years, the domestic industry has been actively promoting on the market the KAZ of the Arena family, designed for installation on the main Tanks and other Russian-made armored vehicles.


KAZ "Arena"

The first version of the Arena complex was created in the eighties by the Kolomna Engineering Design Bureau. The development of the system was headed by N.I. Guschin. Initially promising KAZ was intended for installation on the main tanks T-80. For a number of objective reasons, the first public demonstration of the new system took place only in 1997 year. The complex "Arena" attracted the attention of specialists and became the subject of numerous disputes, which do not cease to this day.

Shown in the late nineties, KAZ "Arena" consisted of several basic systems. The complex included detection and control equipment, weapons, and control and test equipment. It was proposed to install all the facilities of the complex on the existing tanks, which made it possible to significantly increase their survivability in real combat conditions.

The principle of operation of the Arena system looked relatively simple. Before entering the battle, the crew of the combat vehicle turns on the KAZ, after which it operates in a fully automatic mode and solves all the problems of protection against flying anti-tank ammunition. The radar of the complex monitors the environment and detects approaching objects that have certain dimensions and speed. If the speed and dimensions of such an object correspond to an anti-tank rocket-propelled grenade or a guided missile, shooting of a protective fragmentation ammunition is made. A directed stream of shrapnel ammunition destroys a dangerous object.

The situation is monitored using a multi-function radar station. This device is located in a characteristic polygonal casing placed on the roof of the tower of the protected machine. The design of the antenna unit allows you to monitor the entire protected sector. Depending on the type of base armored vehicle, KAZ Arena can intercept anti-tank ammunition in a sector of width 220-270 °. In addition, due to the rotation of the tower provides a full all-protection protection.

The radar complex "Arena" has a target detection range at the level of 50 m. This range is sufficient for the timely detection of the threat and response to it by launching protective ammunition. The response time of the systems is stated at the 0,07 level.

Information processing from the radar station is carried out by a computer located inside the base armored vehicle. All units installed inside the hull of the tank, occupy no more than 30 cube. dm Due to the high speeds of weapons, all stages of combat work are carried out automatically and without the participation of the crew. The task of tank crews is only the timely inclusion of all necessary systems.

For the destruction of incoming rockets or grenades, special fragmentation protective ammunition is used. On the cheekbones and sides of the tower base machine mounted a set of special launchers that produce shooting ammunition. Depending on the size of the armored vehicle, the ammunition package of the active protection complex consists of at least 22 protective ammunition.

After the shot, the protective ammunition is removed a few meters from the armored vehicle and is undermined. When undermining fragments form, the trajectory of which intersects the trajectory of flying ammunition. The destruction of a grenade or missile occurs due to mechanical damage to the structure and the initiation of the detonation of the warhead. Undermining occurs at a considerable distance from the armored vehicle, because of which the cumulative warhead can not cause him serious damage.

The automation of the complex not only makes the detection of flying objects, but also performs the selection of potentially dangerous targets. This takes into account the dimensions of the detected object, its speed and flight path. Shooting protective ammunition is made only when it detects a relatively large object moving at a speed from 70 to 700 m / s and able to get into the protected machine. Thus, the consumption of protective ammunition during firing of a machine from a rifle weapons or small-caliber artillery. In addition, the KAZ takes into account the enemy’s blunders and does not attempt to destroy the ammunition passing by or the object entering the radar field of view, but moving from the armored vehicle.

The launchers of the complex are arranged in such a way that the sectors of action of neighboring protective ammunition overlap a little. This, among other things, provides the ability to repel multiple attacks from one direction.

Due to the use of fragmentation protective ammunition, active protection complexes pose a serious danger to infantry escorting tanks. The design of launchers and protective ammunition of KAZ Arena is designed in such a way that all fragments that are not in the threatening object enter the ground at acute angles at a distance of no more than 25-30 m from the base machine. Thus, for safe interaction with tanks or other equipment, the infantrymen must be at a sufficient distance from it.

Complex "Arena" of the first version was quite compact and easy. For the installation of its indoor units, a volume of at most 30 cube is required. dm The total weight of the entire system, depending on the amount of protective ammunition, ranges from 1 to 1,3 t. Thus, the installation of active protection systems has almost no effect on the characteristics of the machine.

The first carriers of KAZ "Arena" were to be tanks of the T-80 family. In 1997, this complex was first introduced as part of the equipment of the T-80UM-1 tank. In the future, it was decided to modify the complex for use on other types of armored vehicles. The result of this was the installation projects of the Arena on the T-72 tank and the infantry fighting vehicle BMP-3. All these projects are based on the same ideas, and their differences lie only in the composition and layout of some systems. On the roof of the armored turret, a rack is mounted with an antenna unit of a radar station. On the frontal and on-board parts of the tower are mounted launchers of protective ammunition. In addition, control systems of the complex are installed inside the fighting compartment. The exact location of the various elements depends on the type of base machine.

Since the end of the nineties, the Engineering Design Bureau, in conjunction with other defense industry enterprises, has presented several prototype armored vehicles equipped with the Arena KAZ. Such modernization of combat vehicles was of some interest to potential customers, but no one wanted to buy the proposed systems. The Russian Ministry of Defense and the military departments of some foreign countries did not order the Arena complexes.

This decision of the military was associated with some serious drawbacks of the complex in the existing version. For example, concern was expressed about the safety of the infantry accompanying the tanks. By destroying enemy ammunition with directed splinters, an active defense complex can injure or kill friendly soldiers. In this case, the infantry for one reason or another does not always have the opportunity to move away from armored vehicles to a safe distance.

In addition, the reason for the claims was the design of the antenna unit radar. This essential element of the complex was proposed to be mounted on the roof of the tower, which entailed a lot of problems. Thus, a large unit on the roof of the turret increases the overall dimensions of the armored vehicle and increases its visibility, which can adversely affect survivability in combat conditions. The second problem of the complex is the lack of serious protection of the antenna unit. According to some reports, the elements of this product can be damaged even by small arms fire. Thus, the key element of KAZ has insufficient survivability, and its damage makes all other devices useless and deprives the armored vehicle of the required protection.

Modernization of KAZ "Arena-E"

The existing shortcomings of the Arena system led to the fact that at the moment no one wanted to acquire it. However, the failure did not stop the work. At the end of the two thousandth Kolomna specialists began to develop a project for the deep modernization of the complex, the purpose of which was to eliminate the existing shortcomings. The result was the emergence of a new KAZ, differing in the layout of the aggregates on the outer surface of the base machine tower.

In 2012, the model of the main tank T-90С with the upgraded KAZ Arena-E was presented for the first time at the exhibition “Technologies in mechanical engineering”. The proposed armored vehicle differs from the existing models by a different composition of protective equipment and its layout. Later a full-fledged sample of the tank, equipped with new equipment, was presented. In recent years, this machine has been a permanent exhibit at various domestic exhibitions.

The largest claims from the specialists and potential customers were caused by a large antenna unit. The new project abandoned this unit, seriously worsening the real characteristics of the machine. A single radar antenna unit was divided into several small devices, which were distributed over the outer surface of the tank turret. The use of a multi-module radar station made it possible to maintain an almost circular view of the space, but did not lead to a noticeable increase in the machine's projection.

Another layout innovation concerns the deployment of launchers for protective ammunition. In the basic project "Arena" these devices are located around the perimeter of the armored turret and are responsible for the protection of certain sectors. The new project involves the use of blocks in which several launchers are combined. Like the individual radar antennas, blocks of launchers are distributed over the roof of the tower and provide protection against attacks from different angles. On the model presented in 2012, four blocks were present, each of which contained at least three protective ammunition.

The exposition of the exhibition Russia Arms Expo 2013 was attended by a full-fledged sample of the tank, equipped with a modernized AAZ-A. This sample had some noticeable differences from the layout presented in 2012. In the new version, the tank receives four blocks of launchers mounted in two casings on the sides of the turret. At the same time, a multi-module radar station is maintained, the elements of which are located in different parts of the tower.

According to reports, the modernized Arena-E complex retains all the basic characteristics of its predecessor. As before, he is able to independently detect targets at distances up to 50 m, determine the degree of danger of a flying object and give the command to fire protective ammunition. The defeat of a rocket or other anti-tank ammunition is made at distances up to 30 m from the tank. In addition, the possibility of two consecutive triggers of starters in the same protection sector is claimed.

The upgraded version of KAZ "Arena" was introduced a few years ago, but, as far as we know, has not yet reached mass production. Potential customers have not yet expressed the desire to purchase these systems and install them on their tanks. At the same time, the proposed complex may indeed be of interest to the military of Russia and other countries. For example, in 2014, the option of installing the complex on T-72B3 tanks was presented. This type of equipment is actively used in the military, and can now be equipped with active protection complexes. However, so far the defense ministry did not talk about its plans to acquire such equipment.

          Check out AnnaNews stories from Syria. Real tanks in real city battles. Infantry generally does not rub near tanks, this would prevent them from maneuvering, and when it is covered by the tank’s hull, it is naturally located on the opposite side from where a rocket can fly.

          Professor I told you, don’t grind nonsense. KAZ is not intended for military operations at all, since it is simply not capable of combating heavy anti-tank weapons, it is not clear how the system will act in case of strong shaking. Many ATGMs (for example, FGM-148 Javelin) hit the roof of the tank, bypassing the protected area. A shell rupture a few meters from the tank will almost certainly damage the equipment located on the roof, including the protective system. Also, the final performance of the system with the need for recharging does not allow to repel multiple attacks from one direction and so on. By the way, your Trophy is a slightly truncated version of the Arena, no new principles have been implemented, the Arena intercepts at farther distances than the Trophy, but everyone has the same problems, and most importantly, target selection, system vulnerability and reloading problems. By the way, Trophy was positioned as KAZ for low-intensity conflicts.

And the question of the probability of infantry defeat will disappear by itself, although there has already been a case of an infantry support officer injured and it turns out you contradict yourself, because you refuse to believe that the system is intended for conflicts of low intensity, because during a military operation, especially when the enemy has armed with heavy anti-tank weapons, it makes sense to create a system that is safe for nearby infantrymen, when a bursting shell or mine near the tank kills them all to hell ... think Professor, and better learn smiling and listen.

                  Professor, here’s a video for you, watch and think about the upper hemisphere, compare the detection range, the interception range and find out from what height Javelin attacks and the like? And in the end, do an experiment, shoot from an RPG, from the fifth floor into the roof of Merkava, I think the system will not even pick up. So there’s no chance. You would refute at least a link given on the video.

                        "By the way, your Trophy is a slightly truncated version of the Arena, no new principles have been implemented, the Arena intercepts at farther distances than the Trophy, but everyone has the same problems, and most importantly, target selection, system vulnerability and reloading problems."
                        "By the way, Trophy was positioned as KAZ for low-intensity conflicts."


                        PS
                        It is a pity that we will not know what is the working element of Trophy? What is the likelihood of infantry defeat? And in the Arena? laughing
                        And if it’s about ravines, then Trophy successfully underwent military “baptism,” or “circumcision,” in our opinion.

                        Professor, is it okay if I answer instead of Ekspert?

                        "Trophy" uses many shock micronuclei (MEFP - Multiple Explosive Formed Penetrators).


                        (open in a separate window)


                        The reaction speed of the Trophy is higher than that of the Arena, since the Trophy only needs to deploy the counter-munition towards the threat.
                        The speed of the “Arena” counter-ammunition cannot be great.
                        For example, the speed of counter-ammunition KAZ "Drozd" - 120 m / s.
                        The speed of shock micronuclei is 2-2.5 km / s, armor penetration is higher than that of the GGE (ready-made damaging elements).
                        Since the shock nuclei are formed by the explosion of blasting explosives (RDX / HMX, etc.), they gain their speed almost instantly, in contrast to the "Arena" counter-ammunition thrown with gunpowder.
                        Also, shock micronuclei can be formed in a narrow sector, and GGEs cover a large area, which poses a great danger to their own infantry.
                        According to Rafael, the likelihood of defeating KAZ Trophy’s own infantry does not exceed 1%.
                        Trophy protects armored vehicles in the upper hemisphere, while Arena is not capable of attacking threats in the upper hemisphere.
                        The "Arena" counter-ammunition occupies a large area, therefore, unlike the "Trophy", they are very vulnerable to heavy machine guns.
                        The arena radar is not protected by anything.
                        The Trophy radar is covered by radiolucent armored ceramics, which protects against rifle bullets and fragments.

    Jews value their people, but ours do not care.

    If we talk about the Arena, then this is complete garbage. For modern conditions it does not fit completely.
    A huge shnyaga, which can be seen per kilometer and can be destroyed by a gun ... Sense?

    The same Trophy is much less vulnerable and more invisible.

    Not for nothing that our new KAZ did.

      as far as I know, another KAZ "Afghanistan" is using on Armata. The principle of ka and in the renewed arena along the way: sectoral shelling. KAZ shells are located at different points and are spaced over the tower body. But so far, it is not reliably clear. That and with Arena if she was really effective, then she would be demonstrated in all. There are very few videos where the Arena is visible at work!

    It is very good that we paid attention to KAZ "Arena"! I always thought that the Arena was undeservedly forgotten; for this system had the potential for improvement from the very beginning. There are various options: 1. With distributed placement of antennas and warheads (variant of Arena-E), 2. By type Ukrainian "Barrier", 3. option with movable warheads (with varying angles of direction of warheads to a vertical position and to both sides of the "vertical"). There is a possibility of improvement of the ammunition: 1. application as fragments of "microcumulative elements" (FEM ) from tungsten alloy (which allows a stream of high-energy fragments to deflect BOPS cores as well); 2. Operation of ammunition by radio command; 3. Control of the angular location and fragmentation angle of the ammunition (using miniature gyroscopes, pulsed rocket micromotors and, possibly, X aerodynamic surfaces). Ensuring the compactness of the warhead (with ammunition) due to the use (as "engines") of powder "pushers" (on the principle of SP-4 cartridges); 5,6. Use of warheads with variable angle th direction (with the help of electric motors) .Such "vzryv.paneli" capable of destroying anti-tank weapons as "directly" attacking and attacking from the top.

      And if in front of a modern "exhibition" tank at a distance of several meters to detonate a high-explosive fragmentation projectile with some kind of radio detonation, then all this will probably go away. All these glass windows, arenas and other gadgets. And if this arena works where another tank is nearby, then the kayak and its arena and other attachments looking in this direction. So they shatter each other. smile

      Laser sights have a fairly small area. The main laser sight, as I understand it, is generally located almost entirely inside the tower; only small lenses stick out, to get into which you still have to manage. I can, of course, be mistaken.

      “Arena”, if I correctly understand the above photos, occupies a very significant area of ​​the tower, so that even a slightly conscientious queue from a machine gun (or, even cooler, from a BMP cannon) will hook it in any way.

      In general, this issue has been haunting me for a long time: on a modern tank there are really a lot of different attachments on the tower (remember at least the “eyes” of the “Curtain” on the T-90), and this equipment is simply unrealistically adequately protected from small arms. At the same time, a tank cannot fight exclusively at distances exceeding the capabilities of small arms: battles are now more often fought in cities than in open field. How to be something?

    In general, it is a huge temptation to create a KAZ that does not emit anything. Instead of a radar, use a multichannel vision system on a stabilized platform. To defeat the flying ammunition, develop a machine gun with a different rate of fire. Of course, such a system will also have disadvantages, but the range of destruction and detection will increase significantly, it will be possible to protect the upper projection of the tank, and the infantry will be safe.

        Judging by the publication "Afghan" breakthrough development. However, it can only be installed on armored vehicles made on the Armata platform. The danger for the "Afganit" will be the AHEAD type projectiles that are aimed at the radiation of the locator.
        The TV channel is certainly not without drawbacks, and therefore should be duplicated by IR and UV channels. Ammunition flying up cannot emit anything. On any channel it will still light up.
        In addition, a similar system can be installed on the same T-72 or BMP.
