“Russian response to anti-submarine fields”: The War Zone about the new Burak-M buoy


Radio buoys on the P-8A Poseidon



Information about the creation in Russia of the Burak-M buoy, which is responsible for electronic suppression, has attracted the attention of US military-related portals. Among them is the edition of The War Zone, which came to unpleasant for the American fleet conclusions.

Dazzle the enemy


The Burak-M functions by passively moving along the sea surface, however, being able to automatically activate the jamming system attached to it. It blocks the transmission of information from sonar buoys of the enemy, collected by their airborne sensors.

As a rule, in Russian standards for naming weapons, the letter “M” at the end means [...] that there was an earlier Burak design, which may already be in service

- notes the publication, indicating that the appearance of a new product will affect the conduct of anti-submarine warfare by traditional means.

Currently, one of the main techniques for detecting and tracking submarines is the dumping by airplanes and helicopters of large arrays of sonar buoys. The information on the whereabouts of the submarines emanating from them aviation, which can either deal with the “problem” itself or transfer data to other weapons.

However, Russia, concentrated on the ground-based EW forces, decided to bring them to the maritime theater, interfering in the form of "Burak-M" with the normal operation of sonar buoys. Now the submarines equipped with this product will be able to "release" the means of jamming and escape from potential pursuit.

As an example of their specific application, a possible scenario with diesel-electric submarines of the Varshavyanka type is given. Unlike many foreign submarines that can be under water for a long time, they do not have advanced engines, which forces them to regularly rise to the surface. In anticipation of the ascent, “Varshavyanka” can release “Burak-M”, quickly recharge the batteries and again go under water.


P-8A Poseidon


Technology fight


The situation is complicated by the situation with anti-submarine aircraft of the US Navy P-8A Poseidon. Previously [since the Second World War], by default, all machines of this skill were equipped with a magnetic anomaly detector [allows you to detect the displacement of the magnetic moment caused by a large object]. However, now there are no DMAs at the Poseidons, as they were abandoned in favor of an improved speaker system, which just includes sonar buoys.

According to The War Zone, the party that launched a new round of struggle at sea are the Russians, who have stepped up patrolling of submarines in the Atlantic and the Arctic. As a countermeasure, the United States, along with its NATO allies, began to create anti-submarine fields in the oceans. The scope of this activity is reflected in the budget requests of the US Navy. For 2021, the fleet is asking for $ 238 million to buy tens of thousands of sonar buoys, although this is less than the amount allocated for the same purpose for 2020.

It does not seem that the United States will curtail its anti-submarine activities in the near future. [Against this background] the news of Burak-M can only be the beginning of a series of reports that Russia has taken other countermeasures

- concludes The War Zone.

      But the number of hydroacoustics with a roof that has gone over will increase by a factor that will determine our same boat with the same acoustic profile at the same time in several places at a time when it will rest peacefully on Kola: moreover, the number of Russian boats will be multiply to the exercises of the NATO Navy, and then they will also leave together in unison laughing

          Stirling for example.
          "A-26 project submarine has a length of 66 meters and a width of 6,75 meters, autonomy of 45 days and can be under water without access to atmospheric oxygen for 18 days. Displacement is 1925 tons and the depth of immersion is 200 meters. Crew 26 people. Boat has an air-independent diesel-stirling-electric power system.

            So you about VNEU? Then in order. A-26 is not at all. Maybe then the Gotland will be replaced. The Gotlands also have Stirling and they are considered one of the most quiet boats in the world. On joint exercises, the American PLO lost to this boat. After which one Gotland was asked to rent to develop methods to combat NPL. You should not compare Stirling, an engine with an external supply of heat with an internal combustion engine. Stirling is much quieter. But our A615 with a closed-cycle diesel engine in the fleet did not take root. And the Japanese have Stirling. And the Chinese took the Swedish installation as a basis.
            As for VNEU on ECG, it’s even easier there. The ECG on the fuel cell turns the main rowing electric motor, the same one that is also powered by the battery.
            So VNEU does not help the RSLA-m determine the location.

            And what do you think ?:

            Since a non-volatile power plant requires a supply of liquid oxygen or hydrogen on board the submarine, and also because of the short range of the underwater path provided by the VNEU, there is a tendency to return in modern designs of nuclear submarines to a traditional diesel-electric circuit using ultra-high lithium polymer batteries.

                While in service there is not one such. This year, perhaps they will accept, it is being completed afloat and has been tested for two years. Only its price because of these LIABs for half a billion has failed. For diesel-electric submarines, this is horse value. Well and yes, these batteries are dangerous.

                  In service there are many of these. Namely DEPL. And as everyone knows, the construction of new ones continues.

                    I wrote about Japanese Soryu on LIABs, and not about all diesel-electric submarines.
                    VNEU provide underwater autonomy from two to four weeks, and DEPL on LIABs will no longer be accurate.
                    Oxygen is stored in a cryogenic state, in some cases outside of a solid case, the installation itself is low-power, the risk is minimal. In any case, there were no accidents for this reason at NAPL yet. But because of the batteries, the wagon and the small trolley.
                    When lithium or polymer batteries become reliable and cheap enough, the most optimal solution would be a combination of VNEU and these batteries.

                  My friend, I’m becoming more and more affirmed in the idea that we just need modernized Lyres. These dances with VNEU, Stirling and so on have been going on for many years and there is no result. So on Poseidon we managed to shove a nuclear installation, but somehow it doesn’t work in a submarine?
                  To increase the combat effectiveness and efficiency of the underwater component of our fleets, we need a modernized Lira.

                    Hi Andrew! I don’t know how Lyra is, but I have a strong suspicion that things will not stop at the Pacific Six and we will rivet Varshavyanka for the whole decade without any VNEU, LIABs of Dollezhal’s eggs, etc.

                    The lithium titanate has its advantages, there are also disadvantages. I do not argue that technology does not stand still and lithium batteries are becoming more reliable. Sooner or later they will be used everywhere. But regarding submarines, the Japanese are still pioneers. It’s more difficult for us. Even under Vysotsky, when it became clear that we would not have VNEU for Lada in the near future, they suggested using LIABs as an alternative. Theoretically, these batteries could go to Varshavyanka. The Chinese had already built Liotech by that time, Rubin was engaged in the development of batteries specifically for submarines. Alas. There are already certified batteries for maritime transport, but not for submarines.

                      There are exactly two minuses: 1. Relatively low specific capacity (175Wh / l, 90Wh / kg)
                      2. High price (about $ 500 per 1 kWh)
                      Everything else is pluses, many of them are unique, for example, operating temperature up to -30 (both discharge and charge, the capacity decreases by only 25%), the resource is more than 15000 charge / discharge cycles in 3C mode, until the capacity decreases by 20%, complete fire safety.
                      The lifter from Liotech didn’t stand nearby, their characteristics are one of the most sloppy even in their type of chemistry (LiFePo4), but even that installed on Lada or the same Varshavyanka could significantly improve their performance. ..

          Justify, please. And, in any case, it’s quite possible to “get on the air” with a higher level signal over the entire width of the range, and then the receiver’s selectivity. If it will be missed on existing buoys (and most likely it will be, due to the low demand for this parameter in existing devices), you will have to develop new ones and change the entire fleet of existing ones, and this is billions and time.

            Raising the periscope and the radio intelligence antenna and finding the radar exposure, there is a chance that you have already been discovered. Secondly, there are also means of optical-electronic and optical-thermal imaging surveillance, which are not recorded by the RTR antenna. Burun from retractable even from a satellite is clearly visible.

                why only bearing and why fuzzy?
                But the RTR of the boat is really only a bearing, there will be no range, and you will have to dive often, although in fact the radar is working far, the radio horizon can be 400 km ...

                  Because the waves. The area of ​​the reflecting surface changes all the time.
                  If the mast is not raised high (and will be done at first), it will generally cover it with a wave.

                    there are statistical methods used for these purposes
                    but just because the mark is fuzzy does not mean that the bearing and range are fuzzy
                    approximately the point will be determined and surrounded by buoys
                    what you propose, the Germans did during the war, read Steel Coffins.

          A boat at periscope depth is visible visually in many cases.
          Diesel can be heard well if there is a buoy or ship in the area
          A specialized radar is quite capable of detecting retractable devices on the surface before turning off the diesel engine and starting the dive.
          And then the problems ....

              the buoy dropped from the plane, especially before the boat leaves the area, is completely silent.
              and the RTR station will determine the RTR, it is only possible that at the same time as the radar determines the presence of the boat.
              Or visually, the lock will be determined if the radar is not turned on
              But diving in the war zone will often have to; the included radars of one type or another will often flicker
              And there’s such an unpleasant thing as a search for analysis of diesel exhaust, and for it what you dived doesn’t matter much, the exhaust is still there — if you find traces of the exhaust, it will be strewed with buoys.

                      here's the thing- non-specialized radar can detect, or maybe not.
                      What will knowledge give you that it can detect with a probability of 0,2? or 0,1? Dive or not?
                      And if a specialized radar station does not work all the time, but turns on in the area, because somewhere beyond the horizon some buoy heard the operation of a diesel engine and suspected a boat in the area and sent the plane to check the square?
                      and now look at everything that they wrote about the probability of finding a retractable boat and estimate how many different probabilities to detect a submarine in this case, if you only react to the work of those radars that clearly detect the boat and ignore those cases where the boat can be detected, and those detection capabilities that are not related to the radar, like gas analysis, for example.

    But won't such a story turn out? ... Americans were tormented by "guessing": are submarines russed in a certain "water area"? What to do ? But do not throw hydroboats in this "water area"? Suddenly, radio interference to these buoys will be detected! Then it will become clear that somewhere in this (!) “Water area” there is a “rushen submarine”! .... But is it possible to use another method against the GABs? ... It leaves at a certain point in the “oceans” .... whether a submarine .... a surface vessel or a “special container”. At the right time, this “special container” begins to imitate the submarine. One of the tasks of the “container” is to make the adversary throw away a significant part of the available reserves of Habs in the “right” area! And if you put a "scuba diving screwdriver" in the "special container" ... so, anyway, it would be great! He would have sailed a “screwdriver” from one buoy to another ... would have stuffed them with “screws”, thereby causing material damage to the adversary ... yes

    Actually, information is not enough for buoy. And if it is electronic warfare, then for what situations it is created is not clear. If he buoy, then his power is small. And further, the height of its antenna, the height of the antennas of the RSLA, (for comparison, the height of the antenna of Poseidon) and the formula for this case, such as this (or rather forgotten)
    ,
    where h is the height of the antennas, and doubt will be added: o (

    Again about buoys;)) The boat on lithium batteries needs to be done, additional battery modules should be taken out of the module in a durable hull with explosive membranes. Calculations show that even with a slight change in the shape of the light hull, Varshavyanka can be upgraded by autonomy to a modern analogue of the VNEU submarine. In our conditions, this can be done relatively quickly.
    And yes, not only lithium is flammable, but also liquid hydrogen, and even iron (suddenly) in the environment of liquid oxygen. And dewar are much inferior in strength to battery cases.
