Detection of foreign submarines by the water area security forces
MPK-170 Project 1124



On the military tricks of peacetime

The area of ​​service of the multipurpose nuclear submarines of the US Navy 50-80 miles southeast of Petropavlovsk-Kamchatsky was known for a long time. But the American aces of the deep sea did not allow themselves to be detected either by submarines or surface ships, evading detection in a timely manner. I really wanted to make them flinch. Then the “great and terrible” lieutenant-captain Nikonov V.N. (yes, it’s not only me who will last the memory of him - the anti-submarine was excellent) offered, through the division command and division commander, to the command of the KVF, a plan for operation “Tug”. The essence of the matter was that the American submariners perfectly classify surface targets and absolutely do not shy away from fishing vessels, and the latter often pass through the area likely to be located by the US Navy reconnaissance submarines.

Two medium fishing freezer trawlers were identified for participation in the operation. And in the summer of 1978 of the year, each of the SRTMs took a tug on one of the IPC Ave. 1124 and, with a small time interval, took the POU KT – 1А POUs to drop down. The screws of the towed ships were locked in order not to create the characteristic unmasking underwater sounds when rotating from the incoming flow of water. Power supply from diesel generators No.2 (DG No.2 were not structurally on the foundations, but were suspended through sound-absorbing shock absorbers to the upper deck). The rest of the observed silence and radio silence. Radar for navigation purposes used only SRTMy. The speed of deployment of ships at given points corresponded to the usual speed of fishing vessels when traveling to fishing areas. Came out at night, with the dawn of the day turned out to be overcast and not stormy. Upon arrival, the ships delivered towing ropes to their points, lowered the OGAS MG – 339 antennas to the optimum depth in accordance with the hydrological section and began to listen to the water column in the direction finding mode using analyzers of discrete noise components (“Cassandra”) from the NPS. SRTMy followed their courses the same speed.

The gloss operation was a success. Two U.S. Navy submarines were discovered in the silo mode at once! It turns out that we found the moment of a shift on reconnaissance duty from one boat to another. Each ship had noise bearings on both nuclear submarines and, exchanging information using the P-770 Grenade group attack system, determined their coordinates accordingly. Since the Americans were calm, it became clear that they did not find us. We were not in a hurry to switch to echo direction finding mode, we gave an alert by the fleet about the detection of IPL and caused anti-submarine Aviation. With the arrival of aviation, they handed them contact with the nuclear submarines and began to work in echo direction finding mode. In general, the surprise for the American Verdruz was completely successful. The total contact time of anti-submarine ships with the detected nuclear submarines was 16 hours, and in total with the PLO aviation, two days!

It was after this operation that the American submariners were forced to shift the area of ​​their intelligence duty another hundred to one hundred fifty miles to the south-east, away from these insidious Russians.

Cats - mice

Outside our territorial waters, almost at the latitude of Sovetskaya Gavan Bay, the patrol ship 50 Ave. “Irkutsk Komsomolets” visually discovered the periscope of an unidentified submarine and gave a special signal about this to the fleet. At this time, the IPC – 4 and the IPC – 155 Ave. 1124 were in the combat training area near the periscope detection site. Of course, the duty officer Admiral of the Pacific Fleet (OD of the Pacific Fleet) at the shortest possible time gave us the order to proceed to the area of ​​the periscope detection to search for a foreign submarine (IPL). Why foreign? Because according to the plan of combat training of the Pacific Fleet in this area, our submarines should not be, if it is not a control target for checking the readiness of our own PLO forces and not lost aces of the sea depths. But we ourselves have already received an alert from the TFR, dismantled it, stopped the implementation of combat training activities and with increasing speed, turning on the “Zavet” screws, and went to the search area of ​​the IPL.

In general, by that time, the anti-submarines had a dissenting opinion on the issue of submitting a notification on the fleet about the discovery of IPL. A single anti-submarine ship (in peacetime) could produce detection either by accident or according to plans of the opposing party. And the ship's anti-submarine shock group (KPUG), too. Submariners always had and now have an absolute superiority in the detection range of surface ships and vessels with their acoustics. Due to the ability to change the immersion depth and having a schedule for the distribution of sound speeds and temperature of outboard water at different depths, they can take a depth to provide maximum ranges in the direction finding mode or in the direction finding mode with their hydroacoustics. Therefore, they effortlessly evade the detection of PLO ships, leaving the KSUG search bar. This tactical superiority of the submarine during the search, which is called the control, is used against them: the submarine evades detection, and we construct the search maneuvering so that, evading detection, the submarine leaves the surveyed area for a while. At the same time, the noise and maneuvering of anti-submarine ships are demonstrative. And even the detection of submarines by surface PLO ships is possible when the submarines are forced to make a breakthrough or the search operation of heterogeneous PLO forces is launched against them and operational connections of heterogeneous anti-submarine forces (OS RPLS) come into play. These are coordinated in time and place, under unified leadership, the actions of multi-purpose submarines, anti-submarine aircraft, surface ships and coastal detection devices aimed at detecting and long-term tracking of detected submarines. But in general, as the “secretary general” said: “The report on the discovery of the submarine and the loss of contact with it must be prepared at the same time.”

So, in order not to be accused by the upper command of the full tactical superiority of the likely enemy (or probable friend, but less likely), the commanders of the PLO ships extremely reluctantly resorted to warning about the detection of IPL by the fleet . Despite the fact that the reporting forms were prepared in advance and it was enough to enter only the coordinates of the detection point and the detection time, although they were transmitted with priority over the fastest communication channels, the fleet’s operational service responded to ships with a half-hour or more delay: it was necessary to parse the report, record it in the on-call documentation, find the Fleet Commander or his deputy, report, receive instructions, spell them in a cipher telegram and send to the ship (submarine, aircraft, helicopter s) for performance. And in thirty minutes the nuclear-powered vessel could double the speed of the underwater course and use the entire arsenal of evasion and sonar noise. And who is to blame for the loss of contact? Yes, the one who installed it. Therefore, those who occasionally made contact with the IPL did not rush to please the entire Pacific Navy.

As a rule, the commanders or chiefs of staffs of anti-submarine surface ships brigades were commanders of the OS RPLS. The commander of the brigade of the ships for the protection of the water area, the captain of the first rank, Arkhontov Gennady Sergeevich (he had the nickname “General Secretary”) with some officers of the brigade headquarters was on my board (MPK – 155). Along the way, they made a decision to search for IPL or use one of the standard search options. They immediately agreed that the IPL commander intentionally allowed himself to be discovered in order to identify the capabilities of the PLO forces and means in the area of ​​the Sakhalin Flotilla base - Sovetskaya Gavan Bay. Entering the ships in the underwater position will be only in case of emergency. It would not be intriguing to evade detection, otherwise why did he show himself? In shallow water will not go (ie, the depth in the area of ​​maneuvering submarines will be at least 120 m). He hardly knew about our presence at sea, since we did not work with acoustics, but worked through preparatory activities for rocket shooting. Now, of course, he has already heard us, but we are coming from the southern direction, from the side where he came from, and where he will dodge. In the northern direction, the territorial waters from the side of Sakhalin and the Khabarovsk Territory are closed and it is possible to break the state border in the course of separation from tracking in that direction. It is undesirable for him, because then he will receive from us an international signal to ascend and in case of non-compliance he will be attacked.

In general, the conclusion is: either the unprecedented arrogance of American submariners or intelligence intent. Based on these considerations, we chose the lowering points of the containers of the low-flow hydroacoustic stations (OGAS) MG-339T, prepared for the measurement of hydrology to refine the forecast data on the detection range of submarines. MPK – 155 and MPK – 4 discovered IPL five minutes after starting the search in the direction finding mode. The submarine was trying to pass between the two ships (breakthrough) and was already heading south. I already wrote about the peculiarities of our hydroacoustics, I will repeat only that it allowed us to detect submarines further than the Don navigation radar detected surface targets. And the system of group attacks P – 770 “Pomegranate” allowed, with only noise from the two ships, to determine the elements of the movement of the target (course and speed) without unmasking themselves with active sonar radiation. Alert on the fleet on the detection of IPL has already been sent. Data for anti-submarine aviation on the nature of the waves in the area (to set the sensitivity of radio-acoustic buoys) sent. In peacetime, the American submariners, after confirming the fact of their discovery, broke away from tracking the PLO surface ships by pattern. They were always aware of the weather conditions on the surface. The direction of the wave can be clearly seen in the anti-aircraft periscope from under the water, without ascent. And therefore, we chose the course of separation from tracking with the direction against the wind and waves on the surface of the water, every 30 minutes DOUBLE DIVING speed of separation (in accordance with the capabilities of the nuclear power plant, NPI). When attempting to move against the wind and the waves following the detachable submarines, surface ships could not develop significant speeds due to the strong impacts of the oncoming waves and due to a sharp decrease in the range of the HFGS from their own noise interference (OGAS was used only “on the foot”). If at the time of detection, the submarine had a speed of 5-6 nodes, then within an hour from the start of the separation, the speed was a 20-24 node. Continued tracking was possible only by PLO aircraft, but having detached itself from surface ships, the submarine switched to the lowest possible noise and performed an evasion maneuver from aviation.

In our case, the commander of the American submarine did not begin to be clever, but went right through, as I have already described above. But the excitement of the water surface favored high speeds of movement. Kombrig ordered the IPC-4 to lift the container and change the lowering point of the OGAS with the maximum stroke, moving southward after the submarine and with some lead, while the IPC-155 continued noise-finding until the new point arrived. The fact that we already knew the American submarine exactly, because the discrete acoustic analyzer (“Kassandra”, KMG-4) allowed us to determine the component of the noise spectrum from the submarine in 12 hertz, and this is a sign of nationality. Our submarines rustled at the discrete frequency 60 hertz (now they and we, to eliminate this noise factor, have returned to the DC systems on the next-generation submarines again!). At the new point, the IPC – 50 began to work with acoustics in the active mode, and we followed the speed of 4 nodes to our new OGAS lowering point. The “Four” made contact with the submarine and guided us through the system of group attacks to the point of the next descent of OGAS. Two PLO Il – 36 aircraft appeared on VHF communications and we proceeded to transfer contact with the IPL from KPUG AUGP (aviation anti-submarine strike group). To facilitate the orientation of our “eagles” among several KPUG ships, onboard roofs were inscribed on the roofs of the IPC logging. This simplest element of interaction with aviation made it unnecessary to lower aircraft to the height of a flight for reading flight numbers, which saved time to transfer contact with IPL, fuel for aircraft and increased flight safety of PLO aircraft. The pilots set up several linear barriers from the RGAB (radiohydroacoustic buoys), and after 38 minutes the commander of the anti-submarine air group reported on the reception of the contact. It was no longer our job, because the boat was still audible in the direction finding mode, but it was already far away.

The PLO-TOF aviation, after receiving contact from the PLO ships, monitored this American submarine for more than 12 hours. When preparing the tracking report, for the first time we were faced with the need to take into account the drift velocity from the current. In other points of the sea this is not so relevant, but in the northern part of the Tatar Strait there is a strong influx of water from the Amur River. And only after taking into account the drift from the current, did the laying of the IPL course acquire its outlines and meaning. Means of hydroacoustic counteraction (GPA) our “Verdrug” did not apply and acted, as we expected, according to a pattern. The report turned out to be a classic one with recordings on recorders, photographs of OGAS screens, sound recording of IPL noises and tapes of a discrete analyzer. KPUG forces from two ships, the contact time with the IPL was 2 hours 17 minutes, and taking into account the efforts of aviation almost fifteen hours. That is, in real conditions, the American nuclear powered icebreaker could be attacked and destroyed in the first ten minutes of contact with PLO ships. But the true anti-submarine warheads always understood that without interaction with anti-submarine aviation they were only carriers of long-acting submarine detection means, and the weapons were only suitable for self-defense.

        How? If in the late 80s, early 90s, US nuclear submarines "climbed" almost into the Kola Bay (the notorious USS Baton Rouge SSN-689, for example, the Kursk incident is also "hanging"), then in later times, including at the moment, it is unlikely that our capabilities for detection, displacement, destruction have increased greatly, given our "outstanding" pace of construction and, accordingly, the adoption of ships by the fleet. Anti-submarine aviation also applies.

    If the commander of the ship is such a vocation, and not by necessity and has good knowledge and experience, then no matter what the enemy is, he will not allow himself to be led by the nose like a boy, but he will also play with him.
    The basis is well-trained personnel, and the technique in the hands of a savage is a pile of scrap metal.

    to cheer up the reader, and as a kind of addition to the article.

    I don’t know what was the name of the commander of the Enterprise, our history does not remember him, but only a famous commander by the name of Murashov served in the glorious submarine fleet in parallel with him. Famous because famous. And that's it. Even later, when he defended his dissertation at the sunset of his youth and brought up the future Murashovs at the school, he continued to remain famous. Every famous person, like any ordinary person, has a Blue Dream, which he strives for all his life. The captain of the second rank Murashov had two of them: a dead loop on a submarine - this time. And the second is to drown the Enterprise. As for the first, it has not yet been implemented (although, who knows, maybe Murashov did it on the sly somewhere in the Mariana Trench, just the achievement has not been recorded by anyone). To me personally, aerobatics in the deep ocean seems to be as probable as a torpedo salvo in a bathtub. But about torpedoes - a little later.

    The Enterprise was of interest to the naval sailor Murashov for many reasons. First of all, a real man always has a thirst for something to shoot from something and certainly hit. Nobody will argue here. Now imagine a professional hunter who has fired only blank cartridges all his adult life, and then you will understand a little the state of the boat commander during combat service, when there are only real torpedoes in the apparatus and on the racks! The glory of Marinesko and Lunin did not give Murashov peace of mind, like any normal submariner without side associations. And when the Americans launched their first nuclear-powered aircraft carrier with the tail number "CVN65", the captain of the second rank Murashov went out on him to attack almost every night. Mentally, of course. And here - can you imagine? - the sadistic admirals from the General Staff of the Navy come up with tracking the aircraft carrier and a very strike group of the then most likely enemy, and entrust, of course, Murashov.

    And one fine day he looks through the periscope - and here it is, "Enterprise", here it is, sweet, as in the palm of your hand, and about fifteen different cruisers, destroyers and other frigates around it - like the Janissaries around Osman Pasha. It means that they know about the existence of Captain 2nd Rank Murashov. Actually, they probably knew: they say that for every Soviet officer older than a major in the CIA, a separate personal file has been opened. If so, then on Murashov there - how to drink - a whole cupboard is allocated. The commander's eyes glittered predatory, and his right index finger mechanically pressed the nonexistent trigger of a nonexistent shotgun several times. Ooh, bastard! - the sun is shining, the planes take off from the catapults, the antennas are spinning - and you can't shoot even once. Peace on the planet must not be disturbed. Now, if they had given a command from Moscow ... Although I didn't really want to have a third world war either. How to be? Tracking a potential enemy implies a simple, in general, thing: keep him, the foe, at gunpoint and wait for the signal. They will give a signal - swamp, they will not give - do not swamp, be patient, hold on and wait when they say to drown, or another will replace you in three months.

    This difficult hunt, I can tell you, is like staring at a glass of cold kefir or beer for three hours with a hangover, and your hands are tied intently ... And inside the boat there is not a sanatorium with swimming pools and girls. A submarine is simply an iron can, covered from the outside with a thick layer of rubber. Introduced, right? And what else is attracted to submariners? In-in. One day, others, third ... And how you want to slap! Sign, as on the Reichstag, only instead of the chalk inscription "There was a captain of the 2nd rank Murashov!" - a hole in two trams. Here it would be, just in the middle ... even at night it can be clearly seen ... And this bastard is deliberately mocking him? - exactly at midnight he began to start up the planes: take-off-landing, take-off-landing, back and forth ... Lights are blinking, beckoning ...

      And nylon patience, finally, could not withstand the constant friction about the boundary between mental and physical labor, which is daily washed by Soviet submariners. The nylon patience loudly snapped, and the echo was scattered throughout the compartments like a fan of commands. The commander, in his hearts, ran his fist on the table, waking the officer on duty. - Enough, ...! Torpedo attack! And the whole central looked at his commander with delight. “For educational purposes,” Murashov added, somewhat cooling the ardor of the crew. - Target - "Enterprise". The night, however. We’ll crawl right up to the board, they’ll notice the hell. A miner crawled into the central one. “In fact, training, comrade commander?” “Training,” the commander confirmed. - Bubble. Free the fifth and sixth devices. And I imagined the American acoustics, and after them all the other races run to the upper deck and panicked overboard. The noise of the air spat out of the torpedo tube cannot be confused with anything, but go and see if the torpedo came out with the air or not ... At such a distance! The commander rubbed his hands in anticipation of the pleasant. Hold on, adversary. Hold on, honey. The periscope fell down, reports on the readiness of the compartments poured into the central heap, and a general unscheduled event began under the exciting name of a "torpedo attack." - The fifth and sixth devices - that-ovs! ... Fifth, sixth - or !!! Hissing, gurgling, the boat falls a little into the depths. Murashov, having closed his eyes in bliss, imagines the picture that is now taking place above ... Now would have a shot! Okay. Unable to stand it, the commander sets: - To the periscope depth! Raise the periscope! Well, what's up there? So ... Looked at the eyepieces, turned, so-so ... found the Enterprise, and ... Mom! .. No. MUM! MOMMY !!! - Mineer! Miner, your anhydride in manganese peroxide !!! - Here is the miner ...- What did you shoot, the poor Romanian?! - Comrade ...- I’m you ... I... What did he shoot with, fascist?! - I didn’t shoot anything ... - How is it - nothing? here they agreed with the mechanic that he would blow out at the moment of the volley of the latrine - the sound effect was the same, but at the same time we would throw the shit out, they didn’t blow out for two weeks, how much you could carry it with you! (Miner wonders - why me?) Count the torpedoes !!! - Comrade ... and what happened? - What happened, what happened ... Enterprise is on fire !!! Consider it, govnostrel-craftsman! Miner shrugged and went to poke a finger on the shelves, plus in the machines, plus feed. And in the periscope - a picture !!! Take a look? Wow, it's on fire! It burns well. Not just burning, burning. In the dark cool seen. The sight ... Smoke, flames, people run around the flight deck with small insects - in short, a complete set. Got a bad game! Dolbanuli "Enterprise"! This is not a huhra-mukhra. Oh, what will be! .. The special agent sticks out in the middle of the central one and still cannot make a decision - speechless .- Central miner! Comrade Commander, all the torpedoes are in place! I don’t know what it is. Is it really on fire? ”“ Pashel! .. Look for what drowned this iron, and until you find it ...- No, well, shit - it's unlikely. That is ... Yes! And what, in fact, drown already? - ............................. !!!!!!! As you know, accidents in the world can not be.

        end

        For a long time still poor captain of the 2nd rank Murashov puzzled over the causal relationship connecting together a battle gust, an air bubble, feces and a knocked-out aircraft carrier ... Long and in vain. Because everything was very simple: once there are flights, it means that the aircraft carrier must go at the same speed and one course, so that the pilot does not miss when landing. He walked. And then they heard a bubble, then they saw a periscope in the middle of the lunar path, well, nerves passed. A hefty boat swerved, dodging the "torpedo", and the airplane landed a little the wrong way - straight into the central superstructure of the aircraft carrier, the "island" is called ... Well, bang-bang, and all that stuff, as the famous Robert Burns said. In addition, to their cruiser URO (*) "Belknap" in the cheekbone of the nose slammed. Meanwhile, our torpedoes were counted under water, stunned ... And all because the Americans do not have the equipment that distinguishes boats by the smell of feces. True, we also ...

        At the pier in the base, the boat was met personally by the commander of the fleet. He listened to the report, frowning, and when the commander was already preparing to insert, he laid out two stars for him: one - Red - on the chest, the second - smaller - on the shoulder strap. In addition to those already available. And he said: - Go, you better, Murashov, to the school. Teach future naval commanders there, but it’s dangerous to leave you here - what good, you’ll even try to make your first dream come true ... And six months later, the Enterprise underwent an unscheduled repair and again went out to plow the open spaces and start up aviation, and again someone was chasing after it .. And he was so clean, brand new, with a needle, under the striped flag, and nothing reminded that not so long ago "There was a cap. 2 r. Murashov" ...

        (*) Cruiser URO - a cruiser with Guided Missile Equipment, also called a missile cruiser

    This article is interesting, but this article is about how it WAS under the Union. I know how it was in the 90s, I served on the coastal HAK. We saw the IPL, once even the adversary crawled into the terraces. So, our operative reported to the headquarters of the flotilla and from there, after a pause, he was ordered to forget about this episode and do not make notes in the journal. The reasons for this muck are very typical for that time: the fleet should be reported to the operational fleet, which, naturally, will order anti-submarine funds to be raised, and these funds with empty tanks already for a year rested against the wall, so there was no desire to get a hat. But at that time there were no sunbeds, but there were ships at least, and now what are we going to scare these IPLs with?

    Please tell us more about the international ascent signal. Is it transmitted through the ZPS system or by explosive sources? What is the frequency and code of the signal?

    Submariners and their opponents are anti-submariners, in my opinion the fleet’s elite.

    The author of the article answered you)

    INTERNATIONAL SIGNAL FOR SUBMERSION OF A SUBMARINE. It is produced by explosive sources of low-power sound (RG-42 grenades, detonators from deep bombs BB-1 or BPS - K-3M, and for the fuse you can set the depth of the explosion) the signal consists of three series of explosions: three explosions with an interval of three minutes; interval of six minutes; three explosions with an interval of three minutes; interval of six minutes; three explosions at intervals of one minute. If there is no reaction from the side of the submarine along the bearing from the submarine, three RSLs are launched with an interval of one minute (or the discharge of three depth-of-depth bombs BB-1 (BPS) with an explosion depth at the estimated depth of the submarine’s immersion (usually at the depth of the sound velocity jump layer). in the case of a submarine surfacing in peacetime, its nationality is determined and a ship is allocated to lead the submarine to bring it into neutral waters with the shortest safe course.After leaving the territorial waters, the ships wish each other a happy voyage and diverge according to their plans.
