What is dangerous Sea Hunter and how to deal with it

54
The United States is actively engaged in the direction of unmanned surface ships for various purposes. One of the most interesting projects of this kind is the construction of an autonomous anti-submarine defense boat, known as the ACTUV / MDUSV / Sea Hunter. While this BEC is on the test, but in the future it can go into service. The task of the "Sea Hunter" will be to patrol specified areas and search for potential enemy submarines. Obviously, the new American BEC will pose a threat to Russian submarines, and therefore it is necessary to look for methods to counter it.

Boat and its capabilities


The Sea Hunter BEC is currently the main result of the ACTUV program (ASW Continuous Trail Unmanned Vessel - “PLO Cruise Ship for Long Trials”). It was developed from the beginning of the tenths, and in 2016, it was launched and tested. Since then, “Sea Hunter” has solved a lot of problems of various kinds and has shown its capabilities. So, recently the boat independently and autonomously made its way from California to the Hawaiian Islands and then came back.





Sea Hunter is a boat-trimaran 40 long m and full displacement 145 t. Most of the onboard equipment is placed in a narrow main body. Two smaller outriggers are also used. A characteristic feature of an experienced BEC is the presence of a cabin for the crew - if necessary, it can be controlled by people.

"Sea Hunter" has a power plant in the form of two economical diesel engines associated with two propellers. The screws are equipped with cable and net protection. The boat can reach speeds up to 27 nodes. Autonomy is determined by the peculiarities of the tasks and fuel supply. According to the terms of reference, Sea Hunter should work on the open sea for 1-3 months. It is ensured that it works under agitation up to 5 points and survives with 7 points.

The on-board equipment is able to take into account information from various sensors and sources and control the operation of the boat. It is possible to make transitions along a certain route with the handling of dangerous areas, patrolling of designated areas, etc. In parallel, the BEC should conduct a search for underwater objects. In the future we plan to equip it with our own weapons for the destruction of the submarines found.

One of the main elements of the ACTUV program is a promising compact hydroacoustic complex for the new BEC. With the help of active and passive means the boat should monitor the underwater situation. Information on identified objects is transmitted to the operator or consumers. The person must decide on further actions of the PLO.



Particularly marked low cost operation of new technology. The day of Sea Hunter operational work will cost taxpayers 15-20 thousand dollars. The work of the destroyer for the same period will cost more than 700 thousands. The cost of building a destroyer and a boat also differ by orders of magnitude.

While the Sea Hunter is on trial. After all the necessary checks have been made, BEC can be put into service. According to the latest reports, in the 2020 fiscal year, the Pentagon plans to spend 400 million dollars on two promising large BECs. However, it has not yet been clarified which boats are in question. It is possible that two new ACTUV / MDSUV boats will be purchased.

Than it is dangerous


The Sea Hunter was designed as a relatively simple and cheap tool for finding enemy submarines. It is assumed that the "Hunters" in large numbers will patrol dangerous areas and identify threats. Depending on the further development of the project, BEC will be able to call Aviation or PLO ships, and independently destroy the found target.

Unfortunately, the exact characteristics of the GAK of the new boat remain unknown. Apparently, he uses the well-known principles of location, but his parameters were not announced. This does not allow to fully evaluate the new American developments.



The main danger of the Sea Hunter BEC for submarines is associated with the possibility of mass construction and full-scale operation. Unlike large and expensive ships, small and cheap boats will be able to work together and cover the designated waters. In addition, such cover areas will be less expensive. Recent tests have shown that "Sea Hunters" can work both in the coastal and in the marine zone. This provides full interaction with other surface ships, submarines and anti-submarine aircraft.

With the help of the new US Navy technology will be able in the shortest time to deploy in a dangerous area a whole network of boats with GAK capable of causing carriers of weapons. High fuel autonomy will ensure long-term preservation of the PLO milestone and the possibility of moving it in the right direction. Overcoming such a barrier will be an extremely difficult task for the submarines.

First of all, anti-submarine BEC is planned to deploy along the shores of the United States. They will be able to work both in the coastal and in the near or far sea zone. This will ensure the removal of the lines of detection of submarines at a sufficient distance. The possibility of including "Sea Hunters" in the carrier strike groups is also being considered. In this case, the boats will interact with surface ships and provide PLO warrants in the open sea.

Sea Hunter has a limited size and displacement, which does not allow to equip it with a developed set of anti-submarine weapons. At the same time, installation of compact launchers or bomb spreaders is possible. The limited ammunition of a separate BEC will be compensated by the ability to call other combat units.



Thus, with the successful completion of the current program ACTUV / MDSUV, the US Navy will receive a modern and convenient tool for improving anti-submarine defense. The advantages of unmanned systems are actively realized in various fields, and in the future they can contribute to the improvement of the US Navy PLO.

What to do with him


The development and future construction of the BEC Sea Hunter is aimed at reducing the potential of submarine forces of third countries. Boats will search for submarines, and, in turn, they will have to overcome new frontier lines. The American side does not hide the fact that the creation of new BEC for PLO is associated with the construction of submarines in Russia and China.

The best way to overcome the frontiers of defense is to get around them. The mass of crewless boats with the ability to quickly deploy in different areas complicates this task. Fleets China or Russia will have to search for BECs and identify areas of their deployment. In accordance with this information, submarine patrol routes should be planned or adjusted. To solve such problems, you need to use satellite, radio engineering and other types of intelligence.

However, situations are possible in which the submarine will have to break through the line of defense. In this case, the secrecy issues underlying any submarine project come to the fore. The limited physical fields of the boat, the absence of unmasking radiation, and the efficient use of natural factors contribute to a successful breakthrough. Unfortunately, the characteristics of Sea Hunter SAC are classified, and therefore it is difficult to say exactly how a submarine can pass by it unnoticed.



With the help of the BEC Sea Hunter and the like, it is proposed to cover the US coast and ship groups on the high seas. They should form a closed zone around the protected object, but the dimensions of this zone are not infinite. An enemy submarine can strike from outside the protected area. Thus, missiles of different classes with a range of hundreds of kilometers can become an effective means of countering new BECs. Using them, the submarine leaves the enemy's submarine, although the missiles can be intercepted by air defense.

In the context of unmanned systems, one can also recall the electronic warfare, but its application does not look particularly useful. To suppress the BEC radio communication, the EW station carrier must approach them at a certain distance. At the same time, he unmasks himself and becomes a priority goal.

However, all these considerations so far belong to the distant future. At the moment, the main enemy of the Sea Hunter and the ACTUV program as a whole are technical difficulties and the need for further funding. Without solving all the problems of this kind, Sea Hunter or other BECs have no real prospects.

Threat from the future


Currently, the only experienced Sea Hunter BEC is being tested and demonstrates very high performance. In the future, it may enter mass production, which is necessary for the formation of full-fledged beskipazhnyh groups. Thus, in a few years, the US Navy may have a fundamentally new element of anti-submarine defense.

New boats significantly increase the potential of PLO, but are unlikely to make it fundamentally irresistible. The competing countries of the United States must take this into account and plan the development of their submarine forces and the navy as a whole accordingly. If the Pentagon manages to bring the Sea Hunter boat or other similar developments to full operation, third countries will be ready for such threats. Otherwise, they will still remain in a favorable position, since they will receive a developed fleet.

        Drake beckons to decoy duck. Maybe, as an option, develop some kind of acoustic torpedo simulating noise and other (sound, frequency, electromagnetic) parameters of the submarine, which would be activated some time after launch. Let these "sea hunters" patrol the area and let them chase after her, and then go into the gap. Only now you still need to have a detection system that will show them before they can detect you. Maybe naive (not a submariner even once). But most likely this problem can be solved, because as practice shows, for any stray invented by a person, there is another neutralizing stray invented by another person.

        It’s immediately obvious that you have nothing to do with the fleet or technology. In order for many robots to fight, they must be served by a huge number of people.
        In order for a weapon to kill qualitatively, it must be serviced. How to service a hundred plastic bunkers, which, after another storm with a thunderstorm, do not get in touch with something?
        The weapon itself (what they actually will be bulletin for) is still a joke. A hundred drones per 1 nuclear submarine? How are they her? At a depth of 500m, if they notice what they will do? Jokes will tell?

          Well, the Americans do create maintenance-free drones. What is shown in the photo is a simple prototype for working out the concept. in the series there will be drones with a displacement of the order of 1000 tons. And with seaworthiness they will be all right. Out of service is decided upon entering the base. In principle, there are no problems with the mover and mover. Simple scheduled maintenance. In terms of acoustics and radar, in principle, there will also be no problems.
          The second one. The main purpose of such drones is to push the line of detection of nuclear submarines to a sufficiently large distance from the coast. The boat that is detected and maintained is no longer a danger. It is just a goal! And most importantly, this line can be quickly created in places that are dangerous at the moment. This does not create a network of passive hydrophones, the location of which the enemy knows.
          Third! In a displacement of 1000 tons, it is quite possible to shove a dozen torpedoes. What are the most modern amers? In my Mk-48 ADCAP. And such drones located at a distance of 15-20 miles from each other completely cover a certain direction and create a line that the boat can’t overcome without finding itself.
          The world is changing, however, like technology. Unfortunately, our nuclear submarines will be forced to huddle to their shores. And the flight time for a ballistic missile to strike back is important and critical. Especially given the successes (at least in the reports) of the states in terms of intercepting precisely ballistic missiles.

    The combat stability of these drones is unknown. Although it can be assumed that they will not have self-defense weapons. Therefore, a) someone should also cover them, b) hundreds of drones, these are potentially thousands of malfunctions on them. You can act from the hunt for them with UAVs and aircraft by mini-missiles, to the release of surface kamikaze drones. Submarines can also carry minitorpedas in the amount of tens of pieces. There is not even a word about surface ships, for them it is an excellent training target.
    So the idea is so-so really. It’s perfect for covering your own coastline, but on the open sea it will be more likely a victim.

      So what's the point - in peacetime you won’t drown them, but they will calmly listen to the water column and graze the boat if there is enough GAS power. And, in which case, their coordinates (submarines) will be known in advance.

    Figure out the drone what is it? wink

    But seriously, a lot depends on the mode in which it will operate, if in the active mode it "shines with a sonar", then it can be noticed much further than it sees itself. If in passive, then the question is how acoustically noisy the body of this trimaran is and how good is its GAK. As far as I understand, now it is one of the most expensive and complex elements of a ship / submarine. If you put it on an expensive one, the advantage of cheapness will be lost, while a cheap one will be ineffective.

    After the discovery - drone snag, let him run. Or is there a concept for launching the LA drones from the submarine, can this ship protect itself from the air threat? In general, there are options.

    Back in the 70s of the last century, in Soviet popular science magazines (TM, Nizh), at an early age, I read several articles about unmanned sailing ships (with 2-3 masts, with a rigid "wing" sail and with a rotary rigid sail system, working on an electric generator), which, in theory, could work in the ocean for up to several years. However, later this topic somehow disappeared. At the same time, there are no fundamental technical difficulties for the construction of a series of such ships (250-300 tons of displacement) for ASW purposes. Hull - with 1 or 2 outriggers to increase stability, made of inexpensive non-magnetic materials (wood, delta-wood, plastic), battery - also relatively inexpensive, can go as cleanly under sail (rigid "wing" on the vertical axis is much more efficient than conventional sails , especially in non-tailwinds) or under the propeller ("rotor" -generator-AkB-GED-propeller). An auto-starting emergency diesel generator can be placed. The equipment is also quite affordable: the GLONASS-NAVSTAR navigation system (navigation can be carried out in automatic mode or with correction from the control center), compiled with an automatic weather station and a compact navigation radar, a satellite data transmission system (with a sufficiently broadband channel for transmission -receiving a significant amount of information), a compact, under-keel passive-active GAS (with the ability to descend to a depth of about 100 m, to reduce interference from wave oscillations in the near-surface layer of the ocean), you can also place a fairly long magnetometer in the hold part of the hull. Controlling electronic computer and 2-4 TA for small torpedoes. Well, as a last resort - a self-liquidator with a remote control to prevent a capture attempt. With a significant series - the cost will not exceed 15-20 million rubles, and dozens of such "Sea Scouts" will make it possible to control a very significant water area.

    Sea Hunter has extremely low seaworthiness, therefore, it can swim only near the shore, and there it is cheaper and more efficient to install bottom-level hydrophones of the underwater lighting system connected to the information network by fiber-optic lines. As a result, at the exit from each naval base / seaport there will be a fully controlled situation up to the boundaries of the territorial waters of 12 miles wide.

    Another thing is that if the enemy uses small-sized underwater drones such as Poseidon, traveling at a speed of no more than 10 knots, hydrophones will have to be installed in steps of 300 - 500 meters, as a result, billions of dollars will be spent and still remain at a broken trough - with a pair the use of underwater drones, one of them will destroy the FOSS, the other will strike at the target.

    the smaller the displacement, the less effective the hook will be, how much weight and volume of hook on the eagle burke is probably like all this trimaran

    The Chinese will like such a boat. They love drones. And you won’t squeeze them with copyright. In general, they will disappear without a trace and be reborn with hieroglyphs on the sides :)

    Any BPA has a major advantage for the command - there is no pilot, no crew. When the commander has a choice - to send combat vehicles with the crew to the task, knowing in advance that even after completing the task, the crew will die - he will hesitate. Here comes the human factor - do not let people die. There is no such factor with BPA. If there is a chance to complete the task, even with the risk of losing the FHT, the commander will take the risk. And most likely, the unit performs the task, even if it will be destroyed afterwards. And this is the main thing that the BPA command gives - the task is completed without risking people's lives. Therefore, any drone, air, ground, surface or underwater, if its technologies are perfect and its communication channels are reliably protected, or more reliably - it Autonomous, dangerous for the enemy. And this unmanned surface submarine hunter is really dangerous for them. First of all, the fact that the command in any case will send him to the attack, without fear of losing him.

    With surface drones, everything is complicated according to the law of the sea, without any "mines" hi.
    I just talked about counteracting submarines to these devices, no more. hi

    Basically, the vessel is WITHOUT A CREW !!! this is a legitimate prize of the one who "found" it !!!
    AI as a living member of the team, so far, does not count! Although the cat was allowed to use a drone! and they wrote him to the team .... then OH, a living soul, God's after all.
    However, you can be recognized as a street child and "adopt" !!!

    - And what, animals have a soul?
