KAZ "Arena-M" must protect Russian armored vehicles from FPV drones of the Armed Forces of Ukraine

17

The threat posed to armored vehicles of all types from cheap civilian quadcopters, re-equipped in a handicraft way into attack ones, forces us to look for more and more effective countermeasures. At first these were homemade “barbecues”, then - homemade electronic warfare systems, now active protection systems, or KAZ, are considered “our everything”.

KAZ is not a decree


The main danger to armored vehicles is a narrowly directed cumulative jet, which can burn through even the thickest tank armor. To protect from her machinery, Soviet designers in the mid-60s of the last century began work on defensive systems that could shoot down anti-tank ammunition on approach.



The KAZ was required to promptly detect the attacking ammunition using a locator and destroy it from the tank’s own launchers. The project of a promising system was called “Porcupine”, but due to a number of technical problems it did not go into production. The developments were used in the Veer complex, which was supposed to quickly and accurately determine an impending threat using optical sensors, but due to their sensitivity to contamination, it also had to be abandoned. Next came the KAZ Azot, equipped with an interference-resistant two-stage radar and capable of intercepting ammunition at close range, when the distance to the tank was reduced to several meters.

However, the military needed a long-range protective system that could detect a threat at a distance of 20 to 500 m and neutralize it using the optimal type of counter-munition. This is how the Drozd KAZ was created, which had eight guides with anti-missiles and a 24,5 GHz radar capable of detecting shells threatening armored vehicles at a distance of up to 330 m. The complex was put into service in 1983.

All the same at the Arena


The next generation of KAZ was the Arena, developed at the Kolomna Mechanical Engineering Design Bureau (KBM) in the early 80s of the last century for protection against anti-tank shaped charges, ATGMs and shells. Unlike its predecessors, the complex could be installed not only on tanks, but also on light armored vehicles - BPM-2 and BMP-3.

The first T-80UM-1 tank, equipped with the Arena KAZ with an estimated cost of 300 thousand dollars per complex, was presented back in 1997. However, it did not enter service with the RF Armed Forces. Work continued on the export version of Arena-E and the domestic version of Arena-M. Judging by the recent visit of Russian Defense Minister Shoigu to Kolomna, the military department is counting on this KAZ as a means of countering enemy kamikaze drones.


General designer of JSC Research and Production Corporation Mechanical Engineering Design Bureau Valery Kashin demonstrated the modernized Arena-M complex to Shoigu:

Here is this kit that is placed directly on the back of the tank, and this kit is placed around it. At the same time, we are now working to make it possible to combat loitering drones. There are speed limits here.

To this, Sergei Kuzhugetovich demanded that the developers speed up:

We need to do it faster.

Indeed, this KAZ can strengthen the line of its own defense of the T-72B3, T-80BVM, T-90M Proryv tanks, as well as the Terminator BMPT and BMP-3. The main problem today is the need to protect the upper hemisphere of Russian armored vehicles, which are suffering from ammunition drops from Ukrainian heavy quadcopters and attacks from high-speed FPV drones turned into kamikazes.

The Arena-M onboard radar provides target search automatically, generating target movement parameters and transmitting them to the computer, which independently selects the type of protective ammunition and its response time. Each counter-munition fires its own sector, and the sectors of closely spaced ammunition in the same direction overlap, which ensures the interception of several targets. The time from target detection to its destruction by a beam of destructive elements is no more than 70 ms, the time for reloading and re-shot is 200-400 ms.

At the same time, the KAZ does not respond to targets located at a distance of more than 50 m from the tank, to small-sized and low-speed targets that do not pose an immediate threat to it, as well as to targets moving away from the tank, including its own projectiles. The infantry accompanying the tank learns that the complex is turned on by a corresponding light signal. The potentially dangerous zone for infantrymen is only 20-30 m.

It is quite obvious that Arena-M has great modernization potential to provide active protection for tanks against kamikaze drones. Massive equipping of Russian armored vehicles with these KAZs will significantly reduce combat losses.

    The tank will gradually turn into a mini-battleship - armor, air defense, radars, anti-drone passive and active protection

    Which again will not go into series?

    We need to do it faster.

    Previously, it was necessary to think and allocate money for development. And then vacate the chair due to complete incompetence.

    Somehow, during the times of the USSR, I heard about testing a microwave product, the result shocked everyone, it burned electronic components around at a good distance, I wonder why this is not used now

      Microwaves cause superficial burns on the human body. It doesn't do much damage, but no one will like it. Plus it’s probably easier to protect yourself from this than from a grenade

      Microwave currents are currents that arise in various conductive materials under the influence of high-frequency magnetic fields. The easiest example to understand is a household microwave oven, which we use to heat sandwiches in our kitchen. The peculiarity of microwave currents is that our products are conductors for them. Warming up occurs due to the fact that a huge number of microcurrents in the volume of a sandwich (for example) close on themselves. Those. N-number of short circuits occur, which are accompanied by the release of N-amounts of heat.
      A person, of course, will be in trouble if he is exposed to a high-intensity microwave field; and UAVs too...

      Well, finally, at least they were dissatisfied and started moving! Better late than never. Although such KAZs were needed yesterday, even the day before yesterday in Chechnya! And how sorry we are for our dead Russian men because of their laziness, greed and sycophancy!
      They've seen incredibly expensive tanks from Kaz!

    Reminds me of the protective shields in the novel Dune. There, in order to overcome the defense, it was necessary to reduce the speed of the impact, otherwise the shield would react. Drones will now slow down to 1 meter per second before impact.

    something similar or ArenaM itself needs to be installed on the turntables, because the radar guns and heat tanks are powerless against laser-guided missiles

    The front needs KAZs like air, like bread! Edrid-Madrid, just yesterday.

    For example, how the disruption of a defense order was influenced under a different system:

    “You have failed our country and our Red Army. You still don’t deign to produce IL-2. Our Red Army now needs Il-2 aircraft like air, like bread. Shenkman gives one IL-2 a day, and Tretyakov gives one or two MiG-3s. This is a mockery of the country, of the Red Army. We don't need MiGs, but IL-2s. If the 18th plant is thinking of shaking itself off from the country by producing one IL-2 per day, then it is cruelly mistaken and will suffer punishment for it,” said the head of the State Defense Committee.

    However, Stalin's threats bore fruit. In September 1941, a “letter of happiness” reached the director of the Ural Engineering Plant, Boris Muzrukov. The head of the USSR asked him to “honestly and on time fulfill orders for the supply of hulls for the KB tank to the Chelyabinsk Tank Plant.”

    “Now I ask and hope that you will fulfill your duty to the Motherland. In a few days you will find yourself violating your duty to the Motherland, I will begin to smash you as criminals who neglect the honor and interests of their Motherland. It cannot be tolerated that our troops suffer at the front from a lack of tanks, while you sit idle and idle in the distant rear,” Stalin wrote.

    The order was carried out. The volume of production at Uralmash from 1941 to 1945 increased eight times compared to pre-war times, and labor productivity increased six times.

    And this was the merit of the management system created then.”

    “It’s a completely different society now. If during the war high-ranking leaders were not only demoted for mistakes, but also imprisoned and shot, now we are seeing a different situation. Stalin's telegrams will have no effect now. They will only take effect when real repression begins. This is the only way it can work."

    As you know, our Guarantor does not surrender his own. Otherwise, Red Chubby wouldn’t have fled the country so unrequitedly. This is just one example of the current autocratic power - a turtle, based on the three pillars of the corrupt-oligarchic kaganate.

    There are no short circuits there... just the frequency um. waves in a microwave lie inside, or are a multiple of, the absorption spectrum of water molecules, which have a dipole moment, so, for example, a dried sandwich will not heat up. I wonder where the mine clearance machines are based on this principle, what the state acceptance department boasted about, which detonate mines 10-20 meters away. And is it even possible to make protection against drones using this principle?

    300 thousand dollars is expensive! Drones cost pennies; we need protective equipment that is comparable in cost. True, you won’t be able to cut much there

    So it's reusable.
    It is placed once, and then simply reloaded as the ammunition is fired.

    Only drones can handle drones.
    What destroys and kills? Tank or shell? Projectile.
    A drone is a projectile without a tank. This is the reason for the high efficiency of the drone.

    Oh, this sect of witnesses Baikatars/Javelins/Himers.
    Now here is the FPV of drones.
    The FPV drone is essentially slow (wheeled cars can get away from them by pressing their sneaker into the floor), extremely vulnerable to interference (it is small and you can’t fit serious radio electronics into it) and, by the way, not the cheapest thing (in comparison with the same artillery ammunition) .
    The only question is the presence in the troops and the ability to use at least banal smoke.
    Not electronic warfare jammers or KAZs (the mass introduction of this will have a very serious impact on the effectiveness of drones) but the most primitive smoke screens, known to the ancient Romans.

    Z.Y. : By the way, for Grads there are even shells specifically for setting smoke... Also, the Ancient Civilization of the Communists made them. And, as far as I know, she even prescribed the use of smoke in the combat regulations of the ground forces.
    But someone is not a reader.

    Z.Y. 2: It is clear that drones have their niche and their use will expand. But it’s still not worth elevating them to the rank of prodigy.
