Reliable anti-torpedo protection is a domestic priority



Today, the anti-torpedoes of the Russian ship complex “Package-NK” have the highest, in comparison with Western models, anti-torpedo potential, and thus provide a reliable defeat of the attacking torpedoes.

Research into the possibility of effectively hitting attacking torpedoes with counter-torpedoes was launched at the State Scientific and Production Enterprise "Region" in the second half of the 80s of the last century. Their foundation was the vast experience in the development of high-precision, with high tactical and technical characteristics, homing systems (HSS) high-speed aviation anti-submarine missiles - APR-2, APR-3, which were highly appreciated not only in the naval aviation of the USSR Navy, but also abroad.

The development of digital technologies allowed in the second half of the 1980-s to raise the question of the possibility of high-precision targeting of high-speed underwater weapons (anti-torpedoes) at a high-speed small-sized object (attacking a torpedo). In this case, the customer put extremely stringent requirements on the reliability of solving the problem of anti-torpedo protection (PTZ). Fulfillment of these requirements (the defeat of a torpedo by the criterion of "destruction of the hull") required the provision of very high precision of guidance and the use of a powerful warhead.

Initially, at the end of the 1980-x development was based on domestic digital microelectronics, and the first version of the CAS antitropedo was implemented on it with some limitations, ensuring a reliable solution to the problem of hitting the torpedo only from the board of a submarine.

The development of microelectronics allowed as early as the beginning of the 1990's. raise the question of the possibility of effective use of anti-torpedoes and for the anti-torpedo protection of surface ships. Later it was implemented to the package-NK complex (export version of Package-E).

Despite the difficult for Russia 1990-s, the potential of the SNNP "Region", under the leadership of General Director Shakhidzhanov ES, was not only preserved but significantly developed. The world's first actual targeting of mock-ups of anti-torpedoes to high-speed torpedo targets were made at the Feodosiya Navy range in 1998 year. It should be noted that these tests were carried out in extremely difficult hydrological conditions for the operation of CLS counter-torpedoes. And nevertheless, the tests were successfully carried out with the provision of guidance to the torpedoes with high accuracy, which ensured the “destruction of the hull” of the attacking torpedo under the TTZ.

Today, the Package-NK complex includes:

• small anti-torpedo AT;
• small-sized torpedo to destroy MTT submarines;
• launcher;
• hydroacoustic station for detecting torpedoes and target designation;
• complex management system.

The package-NK complex has a modular design and a large modernization potential. It is not the first year that ships with this unique weapon system have been part of the Russian Navy.

It is interesting to compare the effectiveness of the package-NK complex with similar products (complexes) from other countries. Development of active PTZ complexes with anti-torpedoes in the west was carried out in Germany - Sispider, USA - Tripwire, Italy and France - MU90HK.

The most successful were the development of the US Navy, which ended in June 2014 with an impressive demonstration of the real solution of the PTZ task of the newest aircraft carrier George Bush from torpedoes of the Mc48 type.

Despite the fact that the real full tactical-technical characteristics of the TripWire anti-torpedo were not disclosed by the US Navy, it should be assumed that the high-speed and range of the anti-torpedo was achieved. The assumption is based on the fact that this counter-torpedo applied a unique and extremely complex power plant on lithium fluoride with a closed-cycle turbine.

However, the main criterion for evaluating the effectiveness of the PTZ active complex is not the “table indicators” of products, but the reliability of solving the PTZ problem (destruction of the attacking torpedo). With all its excellent performance in speed, range and compactness, the Tripwire carries a very small warhead, and the layout chosen by the developers significantly limits the maneuverability of the torpedo.

Here it is necessary to emphasize once again, not only that from the very beginning of the domestic development of the customer’s anti-torpedo, the question of ensuring a very high probability of attacking torpedo attacks was firmly raised, but also that all the developer’s efforts (“Region”) were aimed at this, and eventually these requirements were met.

The high complexity of solving the problem itself was most clearly manifested during the development of the active complex PTZ Sispider (Germany), when the developer was already at the final stage of development, during testing in real conditions and according to real goals (torpedoes), he had to make very significant changes in the design of both the complex and the counter-torpedo itself (including those that obviously limited efficiency from the originally planned level):

• the refusal of a “rocket type” launcher in favor of “firing at the side” from an inclined pneumatic launcher significantly limited the effective range (Def) of torpedo attacks;

• a small (insufficient) mass of warheads forced developers to go for a unique solution for Western products - the use of a detonating rocket engine (a similar solution was previously used at the Russian “Igla” SAM).

However, according to the information available in the media, the German developers did not manage to complete the development of the “Sispayder” and bring the reliability of the solution of the PTZ problem to an acceptable level.

The statements of the Evrotorp consortium about the solution of the active PTZ problem by the MU90HK counter-torpedo at the moment seem to be more advertising, since there is no objective information about the actual testing. However, it should be noted that the weight and dimensions parameters and table TTX MU90HK are close to the MTT product of the “Package-NK” complex, and with the corresponding modifications, the MU90HK anti-torpedo can gain its high anti-torpedo potential.

The development of active anti-torpedo protection in JSC "GNPP" Region "continues, including along the path of creating small-sized products (ensuring their high efficiency) and a number of other areas.

Thus, today the anti-torpedoes of the “Package-NK” complex have the highest, in comparison with world analogues, anti-torpedo potential, ensuring reliable defeat of the attacking torpedoes.

        For submarines there are sonar systems.
        on the submarine Schuka-B and Borey, they are located in non-rechargeable torpedo tubes.

        The text of the article says:

        Those. for submarines, this problem was solved earlier.

    The article is curious. It was interesting to read. An important means of protection against torpedoes. Moreover, as I understand it, not only for surface ships, they both have other means - the same bombing. But for submarines, the thing is very necessary.

      IMHO this is just for surface. Bombombets for placing a curtain on the path of a torpedo. And for surface torpedo attack is almost irrelevant. You can recall when the last time was a successful exit in a torpedo attack, like during the Anglo-Argentine war, and then almost a pre-war torpedo on the pre-war cruiser. And there are practically no torpedo weapons on the ships of the adversary. That anti-submarine torpedo weapon is really a serious threat. But against it is maneuvering and traps.

    The material is surface. Not a word about the detection of an attacking torpedo, the reaction time of the complex itself, the ammunition on the carrier? And satellites and ballistic heads are already intercepting, speeds are much higher. As they say: a bullet in a bullet. Only keep military secrets.

    Nothing good, only a backward "expert" can happily talk about the same morally backward complex "Package". What is the backwardness?
    Antitorpeda M-15 range of 1400 m i.e. a torpedo shot passed 1400 m and drowned. Therefore, it is necessary to shoot it when an enemy torpedo traveling at a speed of 50 knots (25 m / s) will be at most 2-2,5 kilometers from your ship, that is, if your hand trembles or your equipment fails, you will not have a second chance.
    Now the MTT torpedo (anti-submarine), not a single self-respecting submarine, will allow the PLO ship to reach the MTT launch range (20 km), but its Mk-48 with a range of 50 km will be happy to board.
    And then, to overcome 20 km at 30 knots of speed (50 knots only after finding the target), the MTT torpedo needs 22 minutes, during which time the enemy’s submarines will simply go beyond the range of our anti-submarine torpedo. Not to mention other protective measures.

      Not everything is as gloomy as you described here. Firstly
      no self-respecting submarine will let the ship PLO

      not a single self-respecting PLO ship will chase a submarine to get closer to it for 20 km. Such ships, for search and destruction of submarines, have a HELICOPTER (with torpedoes) or a missile system firing a TORPEDOUS at a distance of up to hundreds of kilometers. The main thing is to DETECT the submarine, and only to get the tenth thing.
      Second
      i.e. if the hand trembles or the technique fails

      Such complexes operate in a semi-automatic mode, when a person (hand trembles) only needs to GIVE PERMISSION to destroy, and the processor will do the rest and track the target and shoot when and where it is needed. There is nothing to argue about "technology will fail," as they say, but with bad and unreliable technology, there is nothing to go into the ocean for a war ...

      this range appeared not just, but was justified - in the framework of resp. conditions
      yes, now it can and should be increased - in the framework of NEW conditions

      And then to overcome 20 km at 30 knots of speed

      on 20 km there is a rocket
      Yes, and the helicopter will be in time earlier

    The task of fighting against attacking torpedoes is very interesting in itself. There is information about using NORMAL FISHING nets for this purpose. Type a container is fired at the direction of the torpedo and the network blocks the path of the dashboard, it gets entangled in the network and ... the task is completed. For example, in this way the Americans were going to fight against the Soviet long-range torpedo guided by the ship’s track mark. It can be assumed that this method can also be used in torpedoes. There is no need for explosives at all or its minimum on the anti-torpedo. In front of the attacking torpedo, the anti-torpedo opens the network in the form of a parachute. And when the attacking torpedo gets entangled, winding the network onto its screw and pulling a small charge to its body, an explosion occurs ... In any case, the radius of neutralization of the attacking torpedo will significantly exceed the radius of destruction in an explosion, even 80 kg of explosives.

    For a former battalion commander, "no self-respecting PLO ship will chase a submarine to get closer to it for 20 km. Such ships have a HELICOPTER (with torpedoes) or a ROCKET system firing a TORPEDO at a distance of hundreds of kilometers for finding and destroying submarines. Main DETECT Submarine, let alone get the tenth case. "
    Dear first helicopter is not a 100% guarantee of detecting nuclear submarines, secondly, due to weather conditions (for example, in the Atlantic) you cannot lift a helicopter into the air in two days out of three, thirdly take care to name a missile system that fires a torpedo hundreds of kilometers away. I haven’t heard of you before.
    Further “that is, if the hand falters or the equipment fails” it is not necessary to understand in the literal sense, it means a short time from detecting a torpedo to its approach to the target’s board, and here the reaction, the state of the mechanisms, etc. are of great importance. etc.
    As for the "most important thing to discover." Imagine a sticky fly that annoys you, you find it but don’t slam it and it doesn’t give you life for a long time, so what’s the main thing to detect or destroy it all the same?
