Active defense complexes: Russia advances, America buys, Europe tests


On September 29, 2017, the U.S. Army decided to purchase an unknown number of Trophy systems as part of an urgent request. General Dynamics Land Systems is responsible for installing the system on the main combat Tanks M1A2 SEP v2 armored brigade group ABST. It has not yet been officially announced, but it is likely that all 90 ABram tanks of the ABST group will receive KAZ Tgoru. The Jerusalem Post newspaper stated that the system has an estimated cost of about 350 thousand dollars per tank. By March 2019, all M1A2 SEP v2 tanks included in the contract will receive KAZ Trophy. It is planned to deploy these tanks in Europe by 2020.

Prototype tank М1А2 SEPv3, equipped with KAZ Trophy

The complex of active protection Trophy was developed by the Israeli company Rafael Advanced Defense Systems. It consists of a radar company IAI Elta Group with four flat antennas placed on the front and stern parts and sides of the platform, whose task is to determine the attacking ammunition: anti-tank guided missiles (ATGM) and reactive anti-tank grenades (RPG). After determining the direction and speed of the attacking ammunition and the appearance in the interception zone, the MEFP counter-missile is fired off, operating according to the principle of a shock core, which destroys the ammunition in the air approximately in 10-15 meters from the vehicle. The overwhelming majority of modern ATGMs and RPGs equipped with a cumulative warhead lose almost all of their armor-piercing ability if the cumulative jet is damaged. Studies have shown that piercing a cumulative jet with a single metal fragment reduces the armor-piercing ability by more than 70% - the mass of fragments a la shotgun created by the Trophy MEFP counter arm pierces the ammunition warhead in many places and detonates it several meters away from the car, in fact by reducing the impact of the cumulative jet to a minimum.

The purchase of the KAZ Trophy does not necessarily mean that the US Army will adopt this system in large quantities. This is just an urgent request, because the United States is interested in the development and deployment of the modular active protection system (MAPS), which combines active protection and optical-electronic suppression systems and allows using various means - thanks to its modular concept. counteractions included in currently available active protection systems (SAZ; SAZ refers to both active protection complex and optical-electronic suppression complex). It should however be noted that urgent requests are sometimes used by the military of different countries in order to do without lengthy trials, and in some cases also without a tender. The US military claims that the Trophy system was chosen primarily because of its high level of technological sophistication. Unlike other types of SAZs tested by the US military, the Trophy is mounted on combat vehicles operated by the Israeli army, such as the Merkava Mk.4M MBT and the Namer heavy armored personnel carriers.

Drawing concept of "protective dome", created by KAZ Trophy

Prior to the order of the KAZ Trophy, the US Army apparently encountered some problems when trying to integrate the components of the active defense system into the M1А2 Abrams tank. According to the Inside The Army website, the imbalance in mass has become a limiting factor, which also adversely affected the work of the tower. At the end of August, the KAZ Trophy was tested on a stationary tank, after which a full cycle of tests was carried out over 30 days with several real combat scenarios, including shelling of a moving tank.

Tanks М1А2 SEP v2 Abrams, equipped with the KAZ Trophy, as already mentioned, are intended to equip the American contingent stationed in Europe. The development of Russian defense technologies and the increased activity of the Russian military forced the American army to again focus on ground equipment and symmetrical conflicts. The Americans also decided to modernize a certain amount of the Stryker ICV armored vehicle into the new version of the Dragoon, installing one of the SAZs on them so that the Russians could not surpass them in Europe. In addition, Javelin ATGM launchers will be installed on the basic version of the Stryker ICV, while several options are being considered for the installation of short-range anti-aircraft systems.

Prototype of a Stryker armored vehicle equipped with a KAZ Iron Curtain

The US Army is still testing the KAZ Iron Fist of the Israeli Military Industries and KAZ Iron Curtain; The latter system was created by the American company Artis under a contract with the DARPA Advanced Defense Research Authority. Artis installed the KAZ Iron Curtain on the Stryker armored vehicle; It is expected that the tests will last until the end of the year, when the army is an example of the decision to buy this system or install another KAZ on the Styker machines. For example, KAZ Trophy is also available for the Stryker armored vehicle and it would be useful to reduce the number of new types of SAZ purchased by the military, as this will simplify logistics and reduce the cost. However, the countermeasure mechanism of the MEFP Trophy system is considered less suitable for installation on BTR and BMP vehicles. The installation of the Trophy system primarily on the M1 Abrams tank is explained by the priority of this program, funds for which were allocated as a matter of priority in the 2016 year.

The United States also planned to test the Active Defense Active Defense System (ADS) system developed by ADS, a joint venture of German companies Rheinmetall and IBD Deisenroth Engineering, but could not finance the testing of several systems simultaneously. At present, it is not known when and whether the American army will test the ADS system at all - it all depends on the budget. As reported news Defense News Agency, the U.S. Army, is currently interested in at least one more system - it’s clear that this is ADS — but cannot afford to test four different SAZs at the same time. If the army could afford it from a financial point of view, then it would already be testing now. Rheinmetall made an offer to the U.S. Army rather late when negotiations with three other bidders were already completed, although it was able to organize several demonstrations of the capabilities of its system in Europe. During the last known show held in Sweden in June, ADS was able to hit six of the six ATGM vehicles. During previous tests conducted in May 2017, two RPGs fired from close range were stopped by the ADS system, while its sensors ignored smaller threats, for example. 7,62 mm bullets.

Rheinmetall offered to install ADS on the Stryker machine, but the Americans chose instead the KAZ Iron Fist test on the Bradley machine. Due to limitations in mass, available volume and electrical power of the Bradley platform, the KAZ Iron Fist was selected for it, possibly in an easy configuration. Nevertheless, the first tests of the KAZ Iron Fist on the Bradely car will pass only in a few months, because the car must first be upgraded.

Launcher Iron Fist LC

The Netherlands also decided to evaluate the KAZ Iron Fist in order to install it on its CV9035NL BMP. BAE Systems was contracted to install this system into the CV9035 machine, which should be completed at the beginning of 2018. This prototype will then be tested in the Dutch army, which, in case of a positive test outcome, will be able to order the KAZ Iron Fist at least for those operating CV90 infantry vehicles. At IDET 2017, held in the Czech Republic, BAE Systems presented the CV9030 armored vehicle equipped with the Iron Fist Light Configuration (IF-LC) for the first time, but it was an inoperative layout. When installed on the CV9030, KAZ IF-LC includes two dual high-explosive fragmentation grenade launchers, the task of which is to combat anti-tank and RPG.

The DSEI 2017 SAZ Active Defense System was shown on a demo of the Leopard 2 Advanced Technology Demonstrator.

As the company's representative at the DSEI 2017 exhibition said, Germany is evaluating the ADS active protection system for subsequent installation on the Boxer armored personnel carrier. At the same time, it is not known whether Germany plans to install SAZ on its MBT Leopard 2 MBT in the near future. However, in a recent document published by the German Army Command, it is planned to adopt a system of active defense and new dynamic defense, with a special emphasis on protecting the roof of tanks and other armored vehicles from the top-attacking ATGM. The ADS system incorporates special actuators and sensor units installed on the roof to protect against such threats.

One of the Boxer CRV cars, sent for testing in Australia, was also equipped with an ADS complex for protection against ATGM and RPG. Although during testing some ADS prototypes were able to successfully hit armor-piercing piercing shells, including their newest versions, currently the proposed APS system options are not suitable for dealing with kinetic-type projectiles. It is very likely that the ADS system will also be offered (optional) for the Challenger 2 (Challenger 2 LEP) tank upgrade and life extension program, since Rheinmetall is one of the two companies selected for its implementation - owns Gesellschaft fur aktive Schutzsystem - system developer ADS. At one time, from May 2005 to December 2006, the UK worked with the Swedish company Ekers Krutbruk Protection AB, owned by IDB Deisenroth (the second developer of the ADS complex) as part of the KAZ ADS technology demonstration program for the FRES project (Future Rapid Effect System - Advanced Fast System response). After the termination of funding, the FRES project was closed.

Launchers, radar and control panel KAZ GL5

A few months ago, China showed the GL5 active protection complex of its own design. This system, by its general concept, is rather similar to the Soviet KAZ “Drozd” and the new Russian KAZ “Afganit”. It consists of four radar stations (mounted on corners of the hull or tower of the tank) and four fixed “masts” installed either on the roof of the tower or on its sides. On each mast three trunks with protective charges mounted at different angles are fixed. This allows KAZ to provide all-round protection for the tank, while it is worth noting that the GL-5 complex is not capable of shooting down the missiles attacking from above, its protective charges cover the sector in 20 ° in angle of place. The system is controlled from a single control panel installed in the tower.

KAZ GL5 intercepts anti-tank missile

The system uses high-explosive fragmentation grenades capable of intercepting ATGMs, RPGs and cumulative shells fired from tank guns. The interception point is located approximately 10 meters (± 1,5 meters) from the protected machine. The radar has a range of the order of 100 meters. If the attacking ammunition, for example, the ATGM, enters the sector served by radar, the radar switches to tracking mode. In this mode, the computer processes the signal reflected from the target, determining the speed of the ammunition and the approach angle. After processing, the computer determines the sector in which the munition falls, and calculates the meeting point of the munition and the protective projectile and, at the right moment, shoots back the protective charge. In the animated 3-video on the website of the Chinese manufacturer, the company Norinco, it is clear that one protective projectile is launched to defeat an ATGM; however, two protective charges are launched on slow-motion shots (below) of a real attack to defeat one ATGM. This may be a mistake that needs to be corrected, or a flaw in the system, which in some cases may require two defensive projectiles.

      Does this "prototype Stryker armored car" even move? In my opinion, it is overloaded with all sorts of systems that may well stall at the most opportune moment. The crew needs to drive into this for 5 years.

      They won’t attack us (on the contrary, they look at Т14 and think that we’re about to enter Lithuania) Well, I don’t believe that Americans who love their comfort zone will attack us why? we sell oil for a penny, we don’t swing it with a rocket like the DPRK, they won’t leave the comfort zone (and Europeans all the more) I consider as a more serious adversary (at least because of the common thousand-kilometer border of China, now they are laying claims to Altai supposedly there demarcation doesn’t suit them (in Primorye they have already given 1000 hectares of land, by the way with the remains of Damansky)

    I recalled a plot from South Ossetia in August 2008 ... there was an interview with a grenade launcher that destroyed a Georgian tank ... everything is simple, we work in tandem and hit a doublet in a predetermined place (from RPG-7 with simple grenades) ... and that’s it.

      Yes, not everything is simple .. And the BO itself should be in the reach zone of the RPGs, and these 2 RPGs must be in the ranks, with the shooters of the right qualifications, and fall, given that they themselves can also get under fire ..
      There are many different examples - both the destruction of tanks with one successful shot, and a number of penetrations without much harm.
      In the same Syria, the T-90 got onboard ATGM - and the crews alive and the tank only smoke. It’s not even clear - the move is still lost, or it was only stopped to get out ...

        "In the same Syria, the T-90 got onboard ATGM - and crews alive and the tank only smoke" ////

        The jet pierced the hull, but did not touch the charges (or the tank had already fired the ammunition) - it did not detonate. And the crew did not hurt - lucky. Smoke is a sluggish fire inside. Lucky case.

            In the Doomsday War of 1973, there was such an incident in the Golan in a night battle - a “meat grinder”.
            Syrian T-62 fired sideways at Israeli Centurion point-blank
            from several hundred meters. OBPS broke through the tower and flew further.
            The tank drivers jumped out of the tank in shock - no one was killed, light concussions.
            Then they saw that the tank was not smoking, the engine had not stalled, the Syrian had left - they climbed
            back, stuffed holes with a rag. They continued to fight. Lucky ...

              such cases when pierced by a caliber are not uncommon at all, but I’ll tell you another case: in Karabakh, the T-72 fired with a HE shell exactly at the side of the T-55, obviously the HE bomb with a moderator pierced a thin side (a little more than 70mm) and exploded inside the tank’s body, where ammunition was lying at the policeman, the T-55 turned around like a tin can (here you have no loading AZ)

              It smells like Jewish fantasies ... BPS when breaking through the armor drives a bucket of fragments from the back of the armor somewhere inside the case. And these fragments have the speed of a pistol bullet. They fly inside the tank and destroy everything. The fragments are so hot that they burn powder charges without a metal shell.

          The automatic fire control system worked (in general, to try to destroy a tank from one hit, read about the Tanker’s Hero of Russia, when he fought a battle against the Georgian T-1 in Tskhinvali, and the battle is such that the shells in the AZ ended, I don’t know how it didn’t hit the city, or didn’t break through, I myself wasn’t there, so it makes no sense to guess)

      and a nuclear explosion in general will melt the division of tanks, we need to proceed from the one with whom we are fighting, if you talk like that, then we’ll sculpt some missiles and that's it, they don’t need anything, they’ll still burn, so Khrushchev reasoned, so we lost artillery, the only thing is that we are fighting where there is no REB-Afghanistan, Chechnya, Syria, but there are a lot of RPG-7 grenade launchers (the Dushmans had 2-3 grenades with one grenade launcher) and in Grozny, when a tank appeared, they started firing at it from RPG-18 ( A fly) from all the windows (the mower of bucks seems to have a bonus for a wrecked tank from them) so is it not better to put KAZ in order to save the tank worth 3 million bucks (new T-90) from a Chinese-made grenade launcher worth $ 100 (for Chechens such there was a lot of it from somewhere, and high-explosive ones, when we still didn’t produce fragmentation grenades, like you have enough thermobaric)

    The first fragmentation grenade destroys antennas, the second cumulative. It is possible and the third for fidelity. KAZ will not save from RPGs with appropriate tactics. That's why we are not in a hurry to implement it, although the development is already 40 years old.

      The whole theory, but in practice, the first Chechen tank T-80u with KAZ Arena was tested in Grozny, it was shot at in real combat situations (note this is not a drill!) In the city from different angles 18 times! from an RPG, after which he left the battlefield under his own power, the tests were recognized as having taken place with a good result (and think, what would happen if out of these 18, at least 2-3 weren’t shot down? - downed track, fixed tank, crew under the fire of snipers, he will not be able to get out for repairs and run away too) must be put and put on all tanks (by the way, I saw a video where Putin scolded the generals precisely because KAZs didn’t put them (apparently their own dachas are more interested in them, and mothers still give birth to meat)

        nikoliski, you are not right:

        The arena was tested in Grozny, it was shot at in a real combat situation (note this is not a drill!) In the city from different angles 18 times

        In practice, no one has tested the Arena in PCV - one storyteller came up with this myth. The initial version generally had a BMP-3. Just look when the Arena appeared on the tank.

        It is not the general who orders the equipment, but the Ministry of Defense with the money given by the Ministry of Finance. So think about who is to blame and who is not.

    South Korea along the way can do not only smartphones with wireless charging a match thick and here they overtook the Americans, a long time ago they put a copy of our KAZ Arena on the Black Panther and are very satisfied, but here we have a mess going on like in 41, when the walkie-talkies were modern, only for some reason they didn’t have time to deliver them, so it’s with the Arena, only the T72B3 is modernized for some reason without it, or useless against the uncontrollable grenades of the Shtora grenade launchers.

    The author, residual armor penetration after the defeat of KAZ is present. Yes, such that KAZ on lightly armored vehicles does not save from defeat, only keeping the box from large breaks.

    If you take the Cornet caliber and extrapolate to it modern achievements (10 calibers for serial munitions with a molybdenum funnel), it turns out that most light vehicles will open 10-20% of residual armor penetration like a tin can.
