Ukraine has developed a submarine anti-submarine system similar to the US SOSUS

The State Enterprise Kiev Research Institute of Hydraulic Instruments has developed an anti-submarine anti-submarine system for sea depths from 50 to 200 m. There is a similar SOSUS complex (SOund SUrveillance System, Sound Observation System), which ensures the safety of US territorial waters,

Unlike the American counterpart, the Ukrainian development has a more multifunctional purpose and smaller scale. Underwater alarm system for sea depths from 50 to 200 m.

The system consists of autonomous anchor passive radio hydroacoustic stations (ARGAS) and radio receiving coastal posts.

Information about the detected underwater moving object is transmitted to the coastal receiving post of the system using small VHF range beacons.

The range of the VHF radio beacon is limited to the line of sight of the radio receiving antenna and depends on the height of its location. For example, if the receiving antenna is located at an altitude of 200 m. Above sea level, the range of the exhaust beacon is up to 50 km.

The system can be installed in the form of extended barriers or single ARGAS at distances up to 50-70 km from coastal receiving posts.
Depth of installation ARGAS from the surface of the water - from 30 to 60 m.
Target detection range in passive mode - 10 km.
The distance between the ARGAS barrier is from 10 to 20 km. Depending on the conditions of propagation of signals.
The ARGAS battery life is up to 12 months and can be extended at the specific wishes of the customer.

Components:
1. Radio antenna and shore station equipment
2. Released radiohydroacoustic buoys VHF 3 range. Anchor passive radiohydroacoustic 4. Station (ARGAS)
The system is designed to detect submarines moving at different speeds (determines the bearing and range).
Information about the detected underwater moving object is transmitted to the coastal receiving post (1) using the VHF range small-sized exhaust beacons (2).

Good system - is there anything similar to OUR Navy?

[Pashhenko Nikolay]

So I wanted to ask the same question. I never heard that we have something like that.

[Know-nothing]

To solve this problem, primarily for the detection of nuclear submarines (nuclear submarines) in the 60 of the XX century. on the Pacific coast, the Agam Coastal Hydroacoustic Station (BGAS) was established. The Agam complex was deployed along the Kamchatka coast to control the movement of submarines (primarily foreign ones) in the Northwest Pacific Ocean.

The system was a complex of low-frequency receiving antennas (plenary antenna arrays). Each 100x7,5 m antenna contains 2400 hydrophones placed in two planes. Hydrophones are combined in 120 vertical rulers, 20 hydrophones in each (two vertical rows of 10 pieces). The hydrophones and a part of the electronic data processing equipment were placed on a special supporting structure, which provided the possibility of towing the antenna, its installation in a predetermined position (usually at a depth of 200 m, 15 m from the bottom, 25 km from the coast) and rise to the surface seas. The antenna was held at the bottom with two anchors weighing 60 tons each. On the supporting structure there were also two omnidirectional hydrophones that controlled the situation in the area of ​​the antenna installation. Information from the Agam antenna was transmitted to coastal posts via two small-core cables. According to them, BSAS power was supplied.

At the beginning of operation, this complex showed quite good results on the detection of nuclear submarines, but over time, during the collapse of the USSR, with a lack of funding and, accordingly, a decrease in the quality of maintenance, BGAS characteristics and its condition deteriorated significantly. Studies of the operational and tactical characteristics of the Agam BGAS by specialists of the RF Ministry of Defense showed that in recent years it has significantly decreased, the actual range of detection of nuclear submarines, taking into account the seasonality of hydrological conditions in the area of ​​the installation of the BSAS receiving antenna, has decreased from tens of kilometers (when the station was put into operation in 60x years of the last century) up to several km now. The replacement of the receiving antenna (in 1988), the partial replacement of information processing equipment (1991,) did not give the expected increase in the detection ranges of nuclear submarines. The detection and classification of modern nuclear submarines with noise Рш = 0,05 Pa using BGAS in general became problematic even when it was located in close proximity to the receiving antenna, i.e. BGAS "Agam" has ceased to meet the requirements of the tactical and technical specifications for the detection of underwater and surface objects and practically does not fulfill its initial functions.

In 2005, during the dismantling of one of the antennas, the AC-28 had to be rescued, for example (then the English "Scorpio 45" cut the cables, in which the AC-28 got entangled).

[tnship2]

It seems that the TU-95 is still able to detect the boat using a towed buoy. If this method is also not outdated.

[desava]

Never write such a thing anywhere else. Not only is the Tu-95 not engaged in anti-submarine defense issues, so it or any other aircraft is not capable of towing buoys. It is even physically ill presented. Hydroacoustic buoys are simply dumped in the proposed area of ​​the submarine location and they do not move anywhere independently.

Alexey, I'm sorry, but system "not to the Red Army"!
In fact, this is the RSLA of large sizes, with all its inherent disadvantages:
- during installation, where the depth of the slam-shut gun will be located is unknown. And the influence of m. not only seasonal, but also situational: a storm, a large outburst of fresh fresh water, explosions of ammunition, an oil spill, the influence of T * air, and so on; Therefore, if he does not have a system for automatically detecting the PZK axis and automatically deepening the hydrophone to this depth, this is bullshit. Judging by the description, the hydrophone has no such subsystem.
- A radio channel in EW conditions is an extremely unreliable way of transmitting information to a coastal post. American hydrophones of SOSUS hang on cables, therefore they do not depend on the conditions of passage of radio waves.
- for the communication and transmission of information issued r / buoy. Sea water is an extremely aggressive environment, fouling, corrosion ... At the most crucial moment, it simply may not work. What then?
- Confuses the declared D detection - 10 km. There will be no atomic carriers in the World Cup by definition, but to hear good 877 or 636 projects on the economy run (or even on the MAX noise), well ... this even needs the Amers to work hard. I don’t think that Ukrainian colleagues surpassed them in piezoelectric transducers and software for digital processing of g / a signals.
- Now about the main thing for which such systems are created. On the maneuverable forces of the PLO, acting upon receipt of a signal from the ARGAS system. It is good if you have a PLO helicopter with an OGAS (magnetometer), small-sized electric. torpedo under the belly. Then T of obsolescence will be minimal and it will be necessary to carry out "search on call" in the water area of ​​10x10 km. And if the avPLO does not fly in the weather? how long does the PLC get to the area?
So this is an invention of the Soviet period.
But the entrance to the Kola Bay is guarded by a completely different system, based on different physical principles. But this is a fairy tale for "adults", so I will be silent.
In general, something like that.

[Navigator2013]

Can a signal be transmitted along a circuit in a barrier?

[AZB15]

Well, they worked out, maybe they even lowered something into the sea there, everything can be. But who needs this Ukrainian system? No one! I suffered - I suffered (this is about developers).

[APASUS]

Did the Ukrainian Navy order?

[Gronsky]

But what does the Ukrainian Navy have to do with it, what are you really?

[Akim]

Quote: APASUS

And the Ukrainian Navy made an order

Navy. How can we talk about the order - so far this is only a development. KrAZ-6322 was developed in the 10th, accepted into service in the 11th, and the first batch will enter the army only this year.

Actually, in my understanding, the Ministry of Defense or the Navy makes an order for such equipment, and then the institutes gnaw at the granite of science? And here is the project for your own money or not full info about the customer ?????

[Parvulus]

We are waiting for orders from Chinese "comrades" - in their honor "infa".

These to buy! I have no doubt even .. And they will introduce it .. It’s good that this news is not all the brains from Ukraine have flowed ... Respect to the guys

[alone]

The main thing is that, “Kiev Scientific Research Institute of Hydraulic Instruments” has developed the right device. That means they work and work just the same in the right direction, a very useful thing

[Gronsky]

In general, engineers who continue to work in the Ukrainian defense industry need to erect monuments during their lifetime. Let the products go clumsy and imperfect, but a laudable desire on the face.

[varov14]

Almost in the right direction, but applied completely for other purposes

[killganoff]

And why do they need this canoe ??? How and on what theater are they planning to use it? 1. The VHF range does not correspond to the necessary ranges for deployment. Even in the case of a well-chosen location for the installation of buoys and a receiving station, it will drown out the electronic warfare. Now, if by analogy with the American Radio-acoustic buoys, then at least mobility is present there.

[roller2]

The VHF range does not match the required deployment ranges.

What prevents you from installing a transmitter to work through satellite channels? Only its price and the availability of such a channel, and so will VHF polishing, and the range depends on where the receiving station will stand, and especially its height. If you install an antenna in the Crimea in the wreck of the city of Kizilovo, the altitude is 600 meters, then the communication range will be 100 km (theoretically).

drown out EW

And they themselves will do the work of the buoy, the task of the buoy is to identify the enemy, and if he tries to crush the signal of the buoy, then CAM will betray itself.

then there is at least mobility.

Well, the author said a little higher that American buoys are tied to cables ??

Quote: Boa constrictor KAA

American hydrophones of SOSUS hang on cables, therefore they do not depend on the conditions of passage of radio waves.

So which of you is right ??

And the operation of buoys is much cheaper than anti-submarine sorties.

But the thought does not creep in that this system was created to monitor water bodies at the port / base level, and not block the Atlantic Ocean with buoys?

[morpex]

Read above! And they will sell to the same Chinas. To survive, how is it necessary?

[vanaheym]

Why not? Not only Russia, military technology to China to sell.

Underwater burglar alarm system for sea depths from 50 to 200 m.

Doesn't it remind us of "knee-deep sea"?
Just for reference: The Black Sea - 422 km², the greatest depth - 000 m, average - 2210 m.
The system is exclusively for counter-sabotage activities in port waters.
It remains to find out how much the sheepskin?

[roller2]

for sea depths from 50 to 200 m

and who prevents the cable to make longer ?? At the mining stage, 200 m is enough.

[Pajamas]

theoretically the maximum required depth for the system to 500m, I don’t think that working the depth of modern submarines is greater.

[varov14]

It is a pity there is no head that would unite a whole complex of seemingly completely different ideas, but for one purpose. New ways .......

[fedora]

The system is designed to illuminate the underwater environment in the coastal zone at depths of up to 200 m, at a distance of up to 20 km. Pictures, photos and text do not correspond to the current development. There are no submersible buoys, no radio communications, only a simple basic instrument and cable systems, and of course unique software. The system is simple, it is not expensive to create, it is very stable and very effective, both for large-sized and sabotage means. Tests conducted in the last three years have proven its high efficiency. Orders for its delivery have already been received from the most significant Navy, among them the United States and China, unfortunately neither Russia nor Ukraine is among the customers.

[mithridate]

it’s good that not everyone sold out. There are also, it turns out, design organizations ...
