Electronic warfare complexes are capable of solving a wide range of combat missions. First of all, this is the suppression of enemy communication channels. In addition, the jamming station is capable of protecting troops from artillery. In our army, such work is assigned to a specialized mobile jamming station SPR-2M "Rtut-BM". It was put into service at the beginning of the last decade and is actively used in exercises and in real operations.

Family development

In the first half of the eighties, VNII Gradient, together with a number of other enterprises, developed the so-called. interference station for radio fuses SPR-2 or 1L29, code "Mercury-B". It was a special vehicle based on the BTR-70 or BTR-80 with a set of electronic equipment for detecting and suppressing certain radio channels. In 1985, the product "Mercury-B" was put into service, went into series and entered the army.

In the future, work began to improve the existing sample. By replacing a number of key units, it was planned to maintain or expand the functions of the station, as well as improve the performance and operational characteristics. The upgraded version of the project received the designations 1L262, SPR-2M and Mercury-BM.

By the beginning of the XNUMXs, Gradient and other project participants, which are part of the Radioelectronic Technologies concern, successfully completed the Rtut-BM development work. After all the necessary checks and tests, the Ministry of Defense initiated the launch of mass production and began purchasing such equipment.

Station at one of the domestic exhibitions

The first contract for several stations appeared in 2011. Already in 2013, KRET reported on the completion of work and the transfer of finished equipment to the customer. It is curious that in these the news Mercury-BM was first mentioned openly. This project has not been discussed before.

Serial production of 1L262 products was carried out by several enterprises. As reported, the stations were assembled by the Kazan Optical and Mechanical Plant. The caterpillar chassis were supplied by the Muromteplovoz plant, and the electronics were carried out by the All-Russian Research Institute Gradient and NPO Kvant.

In the future, the Ministry of Defense placed the following orders for serial Rtut-BM stations, and also regularly talked about receiving new batches of equipment. Probably, production is still ongoing or was completed in the recent past. In total, the army could receive at least several dozen of these machines. If production is not curtailed, then in the near future we should expect the entry into service of new special machines.

Practical application

The first serial products of "Mercury-BM" entered the combat units in 2012-13, and soon the personnel successfully mastered them. In the future, deliveries and training of crews continued with clear consequences for the combat capability of the formations.

Soon after the start of service, the SPR-2M combat stations began to be involved in various training and exercises. In recent years, the Ministry of Defense has repeatedly reported on the operation of such equipment at training grounds, where it provided protection for its troops and facilities from shelling from a mock enemy, and also suppressed its communication channels. The crews of the Rtut-BM stations worked independently and in cooperation with colleagues using other equipment.

As it has now become known, a number of 1L262 stations were involved in the Special Military Operation in Ukraine. Apparently, this technique is used in different directions and performs all its main tasks. With its help, the protection of advancing troops and their facilities, as well as civilian infrastructure in controlled territories, is ensured.

The details of the operation of "Mercury-BM" in a real operation are still unknown. Perhaps this information will be revealed after the end of the operation.

Technical features

1L262 "Mercury-BM" is a self-propelled electronic warfare station designed to solve specific problems. It is built on the MT-LBu chassis, which provides a sufficient level of mobility and maneuverability in different terrain. The chassis allows you to get into position, deploy and get to work.

On the roof of the base chassis there is a lifting mast with antennas for various purposes. It is hinged in the stern and in the stowed position is laid on the roof. To avoid damage, the antennas are covered with a front lifting cover and an awning. Other equipment, incl. operator's workplace, mounted inside the armored hull.

Radio-electronic equipment operates in the frequency range from 95 to 420 MHz and has an electronic countermeasures potential of 250 watts. Electronic cover is provided for an area up to 50 hectares with a probability of suppressing a flying projectile of 0,8. The operation of all equipment is controlled by only one operator with the help of advanced automation.

Mercury-BM has only two main functions. The main one is the impact on radio fuses of artillery shells. An additional one is the possibility of suppressing radio communication channels in the VHF band. At the same time, several modes of operation with different tasks and degrees of automation are provided. In particular, the station can not only suppress enemy signals, but also conduct reconnaissance in a passive mode.

against projectiles

Two stations of the "Mercury" family were created taking into account foreign technical progress in the field of artillery. The potential enemy is armed with artillery shells and unguided rockets with radio fuses. Such a device in flight, using radar, monitors the height to the ground / target, and detonates the warhead at the optimal distance.

An air blast at a given distance makes it possible to more effectively hit small and area targets with fragments. The task of "Mercury-B / BM" is to counter radio fuses by jamming, as well as preventing their regular operation.

In the course of combat work, the receiving part of the "Mercury-BM" system receives radiation in a wide frequency range and searches for signals characteristic of artillery radio fuses. Within a few microseconds, the equipment detects such a signal and determines its carrier frequency and other features. Then the transmitting part of the complex exposes the appropriate interference. The suppression signal is issued within a few milliseconds.

Antenna in working position

Due to interference, the radio fuse erroneously calculates the height above the target and is prematurely detonated in the air. Such an explosion is less dangerous for people, equipment and objects than a standard one. Fuzes of some types, with such an impact, stop measuring the height and switch to the contact mode of detonation. This also reduces the danger to ground objects, although it does not completely remove it.

Unfortunately, the SPR-2M station cannot affect shells without electronic devices, which to a certain extent limits its combat value. At the same time, a function is provided to suppress communication channels, which can be used against enemy artillerymen. Without the ability to receive target designation or information from spotters, they will not be able to effectively use any projectiles.

In order to protect

Thus, "Mercury-BM" solves one of the most difficult tasks in the field of artillery, namely, it provides at least partial protection against flying projectiles. To counter such a threat, various means and methods are proposed, incl. weapon on new principles. In the Russian project, this problem is solved with the help of electronic interference on different channels and frequencies.

During tests and exercises, the SPR-2M jamming station repeatedly demonstrated a high level of performance and compliance with the terms of reference. Now this technique has got the opportunity to show its capabilities during a real military operation. The exact results of such an application have not yet been disclosed, but it can be expected that the calculations make full use of the potential of their technique.

    The day before yesterday I saw a video of our military correspondent, a complex very similar to the electronic warfare "Leer-3" based on the Tiger, caught a glimpse in the frame, however, they work. I will say a banality but a very important one: electronic warfare stations are different Need, EW stations are different are important.

    Interference station for radio fuses SPR-2M "Mercury-BM"

    Laser fuses are more common abroad, but the station is relevant against the Armed Forces of Ukraine, since they are based on Soviet technology.
    That is why the Shortstop radio fuse jamming station was developed by the American company Condor Systems on an urgent order from the US ground forces during the preparation and conduct of hostilities against Iraq in the Persian Gulf in 1991. The need to create a station was due to the fact that Iraq was armed with a large number of ammunition with radio fuses (RV). From 240% to 60% of the existing 80 types of fuses are radio fuses.
    The Shortstop station is manufactured in three versions: wearable AN / PLQ-7 (weight - 11,3 kg, dimensions - 17x30x45 cm), mobile - AN / VLQ-11 (weight - 22,7 kg, dimensions - 27x40x40 cm) and stationary - AN / GLQ-16 (weight - 21,8 kg, dimensions - 24x40x40 cm).
    The standard set of the station includes an electronic unit, an omnidirectional antenna and a power supply. The radio-electronic unit includes the following main components: a detection receiver, a radio-frequency digital storage device (RDSD), an interference transmitter and a data processing device based on a small-sized high-performance processor.
    The receiver detects and intercepts RV signals at a distance of 7-10 km from the projectile. RTsZU provides high-precision synthesis and re-emission with "false filling" (contains information that the ammunition has approached the target at a distance of 10 m) through the jammer of intercepted signals from the radio fuse. As a result, the radio fuse on the ammunition is triggered and gives a signal to detonate it at a great distance (altitude) from the target. The station is easy to maintain - "turn on and forget". One set of "Shortstop" provides effective coverage of the area up to 12 hectares.

        man-portable, counter-radio-controlled improvised explosive device (IED) jammer

        This is generally different, this is against a transmitter for radio-controlled improvised explosive devices. This is a stupid jammer, it is orders of magnitude simpler.

        This system does not intercept the signal of the projectile in flight, does not analyze the sounding pulse, and does not simulate the reflected signal from the ground.

    Judging by the way ukrov use civil UAVs \ quadrics and there are no problems with communication, then the questions, are there any electronic warfare at all, are arising more and more often ..

      Of course there is, but questions about its quality. That's just 99% of those who are here have no idea what electronic warfare is and how this fight works.
      Everything is very bad with communications, REZ, RER, REP. You won’t look at this “Mercury” without tears, the level of the early 80s.
      It's a shame for the state.

      Yes. They promised that "Krasukha" would turn off communications to almost the entire NATO at once. And how epicly the sailors of "Donald Cook" pissed themselves after the flight of the Su-24 with the station "Khibiny" (which the Su-24 never had).

      On the contrary, it’s enough to even google interviews of dill about our electronic warfare, there are a lot of them and they talk about extremely high efficiency. Actually, apart from the starlink, another connection practically does not work for them, naturally in those areas where this electronic warfare is.

      Yes, some swear words addressed to the General Staff from the very beginning of this special operation, 41 days of art of the Armed Forces of Ukraine and Point U have not yet been destroyed, today I flew to Kramatorsk again - it's not shit to hide the needles, it's simply unrealistic, again, why the counter-battery systems don't work again, where is everything UAVs to search for art why the MO abandoned their entire equipment, we see it is so rich that BMD armored personnel carriers and even Shells with Sun-bakers and command vehicles are abandoned, which cost hundreds of millions of rubles apiece.

    Well, where is the result of Mercury's work in a special operation? During these 3 months, the whole world has already seen what the electronic warfare of the Russian Federation is capable of. Leer-3 works poorly, like that, but the rest is AnalogGovnet, however.
