"Sea Spider" in the fight against torpedoes

36
Against the backdrop of increasing competition in the underwater sphere, anti-torpedo torpedoes are another option to neutralize the threat of submarines. The article will focus on the anti-torpedo system SeaSpider ("Sea Spider") of Atlas Elektronik.

In the Baltic Sea the activity of the naval forces of different countries is always great; the fleets of NATO and Russia are deployed there, and sometimes even Chinese ships come here. Russian and NATO forces are vying for operational space, U.S. Navy ships circling Russian planes at low altitudes, and NATO ships are being pursued by Russian ships. In October 2014, which is considered to be a watershed in NATO-Russia relations, the Swedish Navy pointed to "alien activity underwater", after which for a week they pursued a certain underwater intruder in the Baltic waters, but did not catch anyone. Shallow, limited by the width of the Baltic waters complicate operational actions on the water and under water, but they provide an excellent platform for testing new technologies.

In April 2019, Atlas Elektronik, a marine electronics company and part of the thyssenkrupp Marine Systems (tkMS) technology group, announced the completion of the final test phase of its SeaSpider torpedo torpedo (PTT). According to a statement from Atlas Elektronik, “SeaSpider trials have demonstrated the operability of the entire sensor-operator chain of a vehicle’s anti-torpedo protection system with the ability to detect, classify and localize torpedoes (OKLT).”

The tests were carried out on the Baltic Sea in the Bay of Eckernfjord from a research experimental vessel from the technical center of the German Bundeswehr (WTD - Wehrtechnische Dienststelle 71). A SeaSpider prototype was launched from a surface launcher against threats such as the Toure DM2A3 torpedoes and an autonomous underwater vehicle based on the Mk 37 torpedo. According to Atlas Elektronik, “threats ... were detected and localized using passive and active OKLT tools, and the corresponding data was used to launch SeaSpider. The SeaSpider torpedo seized threats and aimed at the closest point of maximum rapprochement. Successful "interception" - the equivalent closest point of maximum proximity - was confirmed by acoustic and optical means.

Atlas Elektronik added that these tests, as part of a longer testing process, were carried out at the end of the 2017 year; after a comprehensive test evaluation over the course of 2018, the results were approved by the WTD 71 Center.

Torpedo threat


For many years now, the torpedo threat has prevented ships and submarines from walking calmly on the seas. Although almost three 50 years ago, only three ships were sunk in torpedoes, the increased torpedo capabilities make NATO fleets focus their attention on the underwater area.

“At the moment, we see that the threat of submarines and torpedoes is growing,” said Torsten Bochentin, director of development of underwater weapons at Atlas Elektronik. - The standard reaction to areas with a high probability of using torpedoes is “do not enter.” With the growing threat of submarines and torpedoes, currently particularly relevant in marine areas such as the Baltic Sea or the Persian Gulf, “not entering” - in fact, means not acting at all. ”

The development of technology in recent years has increased the capabilities of torpedoes. “We have two big developments,” said Bocentin. “The digital era has finally reached torpedoes.” Thanks to the development of digital intelligence technology, torpedoes have now become smart enough to maintain their own tactical image and classify and respond to contacts. At the same time, simpler torpedoes gained the ability to build their own time-distance diagram using ready-made digital electronics. “Connect with a simple wake guiding device and here you have a torpedo that is not immune to false targets in your hands.”

“The figure also did not pass by the hydroacoustic stations (GAS),” he continued. - If you look at the physical properties of the HAS, the ability to digitally process the signals allows you to fully use the physical potential of the station, as a result, the capabilities of passive sonars have now significantly increased. The sonar capabilities are currently such that false targets and jammers can interfere with torpedoes, but they will nonetheless hit the target. ”

Signal processing in digital ASGs also fits well with the concept of using anti-torpedo torpedoes. “As a supporting technology for the SeaSpider project, it is a kind of partial answer to the question, why didn’t you do this in the 80 of the last century? - noted Bocentin. - Digital technology allows the use of more compact signal processing devices that can be freely programmed to run advanced algorithms. If you compare it with analog electronics or even with hybrid analog-digital systems, it becomes clear that only now in the digital era can we integrate the capabilities necessary for PTT into such a small form factor. ”


Atlas Elektronik wants special capabilities to deal with a torpedo threat in its SeaSpider project


Technological paradigms


Bocentin claims that the SeaSpider project aims to create two paradigms of underwater technology. “The first is the operational paradigm when a torpedo threat carries an unforeseen and. therefore, an unacceptable risk. The second paradigm is the usual way of operating submarine weapons with very large efforts spent on logistics, with a very advanced infrastructure of workshops and a large number of well-trained personnel necessary for servicing, transporting, setting up and using the weapons system. This is really what we want to change, ”he added. The company intends to do this by reducing the cost of design, maintenance and logistics, that is, the total cost of ownership. For example, due to the integration of a jet engine into the SeaSpider torpedo and firing of the SeaSpider from the container, which serves both as a transport and launch mechanism. “Containerization,” as an integrated approach, is designed to “provide the customer with what is easy to handle, which does not force him to pay huge sums for additional systems and services”.

Although PTT concepts and technologies have been around for quite some time, Bochentin claims that the enduring nature of the torpedo threat forces them to develop special-purpose PTTs. “The real problem for the PTT is a torpedo pointing towards the wake, and only through a more specialized system can you deal with it. Atlas has been focusing from the very beginning on our special solution to combat torpedoes pointing at wake tracks. ”

The SeaSpider anti-torpedo torpedo is approximately 2 meters long and 0,21 meters in diameter. It consists of 4 compartments: a rear compartment (classified), a jet engine, a compartment with a warhead (if necessary, replaced with a practical warhead) and a guidance compartment, including a homing system based on sonar. The use of solid fuel means that the engine has no moving parts; the superpressure created in the combustion chamber is transformed into draft due to the outflow of gases through the nozzle.



For anti-torpedo protection of submarines (PZP) homing system, operating in active and passive modes, is supplemented by an interception function. Although the detection frequencies of the SeaSpider PTT are not disclosed, the company’s reference data states that “the active ASG frequency was specially chosen for the optimal detection of torpedoes with guidance on the wake stream and to exclude interference with the ship’s sensors”. Since the main objective of the PTT is to combat such torpedoes, its active and passive functionality “is specially designed to be effective against torpedoes in the area of ​​wake-track weakening,” Bochentin noted. “In general, higher frequencies increase the likelihood of a successful torpedo threat.”

Fully digital monitoring and guidance functions are based on an advanced semiconductor microprocessor, including an inertial measurement unit and designed specifically to provide wake torpedoes, and in the case of a PZP - to intercept. SeaSpider is also powered by an OKLT sonar installed on the launch platform.

Although the development of a single SeaSpider single torpedo focuses on providing anti-torpedo protection for surface ships, it is also planned to use it in anti-torpedo protection of submarines. The use of both a single torpedo and a container launcher means that after the surface protection systems for surface ships appear on the market, the emphasis will be shifted to the anti-torpedo defense of submarines and “ideally, the customer will be able to reconfigure the anti-torpedo protection of submarines or surface ships,” said Bocentin.

“As for the torpedo, we are using a remote fuse with backup shock mode. Tests have shown that a direct strike is a separate opportunity, especially outside the wake, against torpedoes that are not guided by the wake track. We don’t need a direct hit, but as a fallback, it is certainly necessary. ”

Shallow water tests


A surface ship operating in coastal areas requires capabilities that are optimized for offshore shelf conditions, including shallow water, limited access, uneven bottom, and the effect of proximity of the surface and the seabed on the characteristics of the GAS.

“The Baltic Sea is a standard of the shallow sea in the scenario of underwater hostilities. To be effective in the coastal strip, you must be a standard for the coastal zone, if you are not a standard for the coastal zone, the system will not work there. ” Due to the secrecy of the work, Bocentin could not explain how active and passive sensors deal with coastal conditions. "Any new underwater weapon for the first time, Atlas Elektronik sees real-world conditions in Eckernfjord Bay at a depth of 20 meters. ”

A surface ship operating in coastal areas will need to act quickly and at extremely short distances to protect against torpedoes. According to Bocentin, although previous versions of the SeaSpider had a starting engine for delivering torpedoes from their launch tube to the point of falling into the water as far from the ship as possible, tests in the limited waters of the Baltic Sea revealed the need for "reduced reaction time and attack distance." In this regard, the design has two requirements. First, “You need to deliver SeaSpider into the water as quickly as possible close to the protected platform using a downward-facing launch tube. Secondly, “a very fast reaction of our propulsion is necessary, so that we can have instant dynamic ascent and, therefore, can launch a torpedo even in the shallowest areas”.

SeaSpider is pointing at the attack torpedo with the help of a ship OKLT sonar. As part of the integration of the platform with the anti-torpedo during the tests, special attention was paid to data transmission channels from the OKLT sonar to SeaSpider with the possibility of feedback. An OKLT class system, which is essentially an Atlas experimental towed active sonar with OKLT functionality, detects, classifies and captures a threat before transmitting data to the SeaSpider torpedo ship control unit, which provides it with a set of parameters based on this data and launches. This is what we have successfully done in the now-completed series of tests. ”

There are three options for starting the SeaSpider PTT from the carrier platform: using the local control panel (also known as a torpedo installation computer) located near the launch frame or installed on it; either from the operational cabin using a separate console or by downloading the software to an existing multi-functional console. As for the console concepts in the operational cabin “most likely, any standard console will not be a separate console only for SeaSpider, but will be an integral part of a comprehensive anti-torpedo defense,” said Bocentin. This console also includes an OKLT sonar control system.


OKLT sonar container


Although the SeaSpider torpedo per se is a homing weapon, Atlas is interested in developing an OKLT-class system capable of monitoring target acquisition so that when an OKLT sonar provides reliable data about it, “we could follow the“ shot-aim-shot philosophy "If the probability of hitting the target during the initial capture is evaluated negatively."

When launched, air under pressure in the container pushes the SeaSpider torpedo downward. The launch container itself is located on the launch frame (ideally, it is permanently fixed to the carrier platform), through which power is supplied and data is transmitted.

One of the priorities of the SeaSpider project is the development of the cassette launch principle. A cluster-ready combat-ready weapon allows faster deployment and easier logistics. The company's goal is to certify the entire SeaSpider product with a launch container. Launch containers are designed for transportation in standard sea containers.

The development of a combat-ready torpedo using the cassette principle and the launch frame also means that the number of torpedoes on a ship can vary depending on the need. On larger platforms, “for example, cruisers and destroyers, you will need to distribute the launchers along the length of the ship, on the port and starboard side,” Bochanin noted. Smaller ships with shorter cruising ranges need fewer launchers. However, the minimum number of installations is determined in aggregate by such characteristics as, for example, ship size, maneuverability and cruising range.


The research vessel Y 862 of the 748 project of the Bundeswehr Technical Center for Marine Ships and Arms Technology (WTD 71) was used as an experimental platform for testing the active anti-torpedo protection complex. The SeaSpider launch pad and container are visible in the middle of the chassis. Additional testing equipment is transported in containers on deck


Torpedo Tests


In naval trials ending in 2018, "the SeaSpider anti-torpedo was launched from an immovable platform using conventional enemy torpedoes that actually simulated a dynamic scenario."

The next test cycles, which will be carried out in the next few years, since the initial combat readiness is scheduled for the 2023-2024 years according to the schedule, will include testing the wake guidance system when the SeaSpider fires from a moving platform using a torpedo operating in the wake of this platform. This, according to Bocentin, "will be the main milestone of the program." The next stage of testing should end with the product entering the market.

SeaSpider torpedo readiness


The main step in the direction of the planned readiness for operation in the 2023-2024 year will be the appearance of a starting customer or customers by the deadline planned in this schedule. While several NATO fleets, along with the NATO Industrial Advisory Council, are assessing the requirements, capabilities, and options for anti-torpedo protection of surface ships, Bochentin did not name any customers the company works with. However, the German armed forces today are involved in the development and testing of anti-torpedo torpedoes.

The critical role of a launch customer is to facilitate the adoption of weapons systems. “Some things industry itself cannot do. “We need a fleet as a customer with our powerful research structures to complete the qualifications and certification of the systems being developed.”

In order to strengthen cooperation with a potential start-up customer, Atlas Elektronik decided - with the support of the parent company tkMS - to continue proactive development. Atlas teamed up with Canadian-based Magellan Aerospace under a direct contract to develop, certify and qualify explosives for mass production, as well as use Magellan’s extensive experience in jet engine technology.

"An important stage here is the qualification and certification of explosives." While the development of technology and testing has been carried out to date, the serial version of the standard high-explosive charge requires full certification in accordance with NATO standards (STANAG) for low-sensitivity explosives; All production of this option is part of the certification process. The great efforts and lengthy time needed to obtain such a certificate mean that the development of explosives is the “most important step” on the way to increasing the capabilities of SeaSpider. A key part of the development process in 2019 will be collaboration with Magellan and the start of testing explosive charge components.

Contacts between the two companies were confirmed in a press release issued in April 2019 of the year. It states that "Magellan will lead the design and development of the SeaSpider torpedo rocket engine and warhead, including the design, testing, manufacturing and testing of products for compliance with technical requirements."

Bochentin noted that the technologies developed within the SeaSpider program basically reached the 6 availability level (technology demonstration), and some elements are close to the 7 level (subsystem development). Here, the company focuses on developing special components, for example, sonar algorithms.

Another important element in achieving the initial capabilities and thus another area of ​​focus for the 2019 year is the preparation for modeling the capabilities of the SeaSpider anti-torpedo torpedo. “You can’t just check each variable using the PTT, so you can talk about a two-pronged process,” said Bocentin. “On the one hand, you want to have test data at sea that confirms the simulation.” On the other hand, you want to have capabilities that allow you to go beyond that experience at sea with this simulation. ”



The SeaSpider container mounted on the launch frame works as a transport and launch mechanism, which accelerated deployment while simplifying logistics


The need for anti-torpedo protection of NATO fleets is steadily growing, as they may face the threat of torpedo attacks in the North Atlantic, the Baltic Sea and the Eastern Mediterranean.

The NATO command publicly noted the activity of Russian submarines. Perhaps the risks here are not just theoretical. For example, in April 2018, British media reported on a Russian diesel-electric submarine of the Kilo class, which, in preparation for attacks on Syria, came too close to American, British and French forces.

          Why, in your opinion?

          What is the main reason for this failure of the US Navy, despite the fact that enormous and high-tech resources have been expended and experienced and competent developers have been involved, while the task is difficult, but can be solved? Obvious the reason is leadership. The success of fundamentally new, breakthrough programs is largely determined by the personality of their leader. In creating anti-torpedo, an unconditional priority belongs to domestic developers. In the 1998 year, as a result of research and development work carried out since the end of the 80 years, for the first time in the world, the trials of prototypes of domestic anti-torpedoes (GNPP Region, now part of the Tactical Missile Corporation) were crowned with complete success. . The key reason for the success of the creation of the Russian anti-torpedo in the harsh 90's is not only in its strong and courageous developers, but also in the head - the chief designer and general director of the GNPP “Region” E.S. Shahidjanov.
          There were mistakes in this work (the one who does nothing is not mistaken), and it went uneasy. But From the very first steps of development, the most critical components of a promising complex and anti-torpedoes were really tested in difficult marine conditions (it was 1998 year!). That is, the fact that the US Navy was simply afraid to spend all of recent years, despite the pressure from Congress, the “Shakhidzhanov team” conducted immediately - at the initial stage of development. Here it is necessary to note the competent and decisive position of the customer - the then head of the Directorate of Anti-Submarine Arms of the Navy, Rear Admiral V.N. Panferov, who not only began this breakthrough development in the extremely difficult conditions of the 90's, but also organizationally provided it with “research stages”, which made it possible for the developer to carry out the necessary research studies and tests of prototypes that convincingly proved the reality of the work and check the key decisions. The problem is that next time we repeated it only in ... 2013 year. Our anti-torpedo was frankly scared.
          Obviously, in the USA for this development there was no “own Shakhidzhanov” and “own Panferov”. However, taking into account the extremely rigid formulation of anti-torpedo protection issues and their equally stringent control in Congress, the necessary organizational measures in the United States will be taken, and at the beginning of the 2020's effective PTZ systems, which have anti-torpedoes in the ammunition kit, will still be received by the U.S. Navy.

            Well, still worth adding
            You can be proud of what Shakhidzhanov and Panferov did in the 90's., but a very unpleasant fact is that in a good way, their successors should be ashamed today of the results of their work.
            Actually we are still “sitting on the result” of 1998 (while foreign developers are actively working).
            Proposals for the creation of promising domestic complexes (with a multiple of the efficiency increased from the “Package”) have been put on the shelf.

            The West is not only the United States, and the development of anti-torpedoes, with all its complexity, is not the development of a new generation of fighters or submarines in terms of resources.
            It is quite affordable for initiative-driven development without any congresses with subsequent entry to the market or offer to interested parties.
            But we are observing a clearly insufficient involvement of the resource for these purposes. And the question is, why?
            Will not be in demand for some reason?

    The article is a plus.

    However, a torpedo torch as a weapon is a dead end - the task of intercepting torpedoes in the near zone of a ship is performed by an order of magnitude cheaper infantry deep bombs with a magnetic seeker based on SQUID (a sonar seeker does not work in shallow waters like the Baltic because of repeated re-reflection of the sound signal from the bottom and water surface).

    Bochentin noted that the technologies developed as part of the SeaSpider program basically reached the 6 level of readiness (technology demonstration), and some elements are close to the 7 level (development of subsystems)

    The author of this opus (and the company "Atlas") want to declare that THIS is a "towed sonar"?!?!? lol

    I personally see here an EXPERIMENTAL sample of a LOWERED HUS for an EXPERIMENTAL vessel made "on the knee" - which has nothing to do with the real appearance of the GAS TSU PTZ

    As a result of tests at the end of the 2000's, the developer decided on a solution unique to Western companies - the introduction of a significant amount of explosive into the composition of the fuel composition, ensuring the detonation of its remains when the main warhead was detonated. This decision led to the rearrangement of the AT (the control compartment was moved in the nose from the warhead) and the replacement of the fuse.
    All this was a consequence first of all insufficient transport and maneuvering characteristics of the SeaSpider anti-torpedo due to the wrong choice of engine type and mass-dimensional characteristics of the product at the initial stages of development. With considering exhaustion of the project budget and unsuccessful test results in the 2014 year, AtlasElektronik suspended work on the SeaSpider project. According to the latest data, in 2017, work on SeaSpider was resumed, but with Canadian funding and complicity in this project.
    It can be assumed, that the complex with SeaSpider type ATs will nevertheless be brought to a relatively operational state, but a complete solution to its problems (first of all, the short range and the line of destruction of attacking torpedoes, as well as the insufficient probability of solving the problem) is technically impossible. Gross errors at the initial stages of the project are extremely difficult to fix in the future.
    The mistake AtlasElektronik was the transfer of key tests that directly affect the appearance of the complex and the product to the final stages of development. With high probability, it can be assumed that the reason for this is the unreasonable hopes that existed in the 1990 – 2000 years under the conditions of severe restrictions on funds for mathematical modeling. Verification of this simulation took place in the 2011 – 2013 years, already on a practically finished hardware, and only then were gross errors of the beginning of development revealed. The main conclusion from this experience is that mathematical modeling (the so-called dry polygon) should go next to the “wet polygon” (real tests, initially on models and prototypes) and mutually check and complement each other, and the stages of research (advance project) during implementation complex projects must necessarily be presented by the customer to the developer - with the allocation of the necessary funds and deadlines.

      Maxim, don't you tear your heart like that. All the same, the process became irreversible and the quality of materials on the site fell like a "swift jack". Such genres as propaganda and sketch are in the lead. And in them deep knowledge of the issue is rather harmful.
      As far as I remember, a couple of years ago Atlas Elektronik appeared in several corruption proceedings and had serious losses. Really surfaced?

    The issue of introducing anti-torpedoes is especially important today, given the significant lag of passive means of protection - sonar aids (SRS) - from the capabilities of modern torpedoes and their homing systems. Given the unconditional closeness of these issues, it is advisable to identify only the principal points.
    The noise immunity of the homing system of a torpedo is determined by three key parameters: noise immunity from barrage interference from powerful jammers or jammers according to the western classification; distance classification of real goals and simulators (decoy - according to the Western classification); the number of accompanied (analyzed) goals.
    Before the advent of digital SSNs, the noise immunity of all SSN autonomous torpedoes was insufficient. The timely use of even such ineffective anti-theft devices, such as gas curtains and mechanical noise emitters, provided good evasion probabilities for the attacked submarine. Under these conditions, the main factor in ensuring the noise immunity of the salvo in the West was telecontrol (with the possibility of clarifying the elements of the submarine’s target evasion with the SAC of the firing submarine and the corresponding correction of the missile target on the dashboard). The surface ships of the US and NATO Navy, the vast majority of which did not have remote-controlled torpedoes, received a very large ammunition of torpedoes and anti-submarine missiles to carry out multiple submarine attacks.
    In the 80 of the last century, the US Navy's multi-purpose atomic submarines (nuclear submarines) received powerful drifting jamming devices Mk3 and Mk4 in their ammunition. Given the significant level of “side lobes” of directional patterns of analogue hydroacoustic acoustics of that time, their timely use in pairs (high-frequency versus CCF torpedoes and low-frequency versus sonic target designation) in the 80 years almost guaranteed the US Navy to evade anti-submarine forces of the USSR Navy . Success was possible for us, but only through "non-traditional" methods of using weapons (at the level of "military trick").
    Digital CCHs, which appeared in the 1990's, allowed to significantly increase the security of CCHs by obstruction, but this did not affect the real distance of classification of targets. In fact, at this stage of development, the response radii of heavy torpedo SSNs reached 3 – 5 km, however, the set of classification features of narrow-band SSNs steadily worked at distances less than 1 km. Thus, between the detection distance and the classification distance, a huge “window” was formed (of the order of 25 – 30% of the detection distance), in which submarine simulators could be used very efficiently provided they were timely and massively used in combination with drifting interference devices. A classic example of such a highly efficient PTZ complex of the 1990 period was WASS C-303 / S.
    TIME REQUIRES ANTITORPED
    Beginning in the 1990's, the main direction of the development of the SSN was to increase the classification distance. One of the means here was a significant expansion of the frequency band of the CCH up to an octave or more. This fact is not fully appreciated by domestic experts. There is a thesis about the “non-optimality” of increasing the operating range due to a significant reduction in range in its high-frequency part. But the key parameter of the SSN today is not the “theoretical” maximum response radius in noise-free conditions, but the classification distance, because in 99% of cases the SRPGs will be used in battle, and therefore you need to look at the capabilities of torpedoes in such conditions. The preservation of the high-frequency operation range (up to 80 – 90 KHz with conventional torpedo 20 – 35 KHz) in the new Western SRGD PTZ also makes us think.
    As mentioned above, the effectiveness of powerful drifting jamming devices (“jammers”) with the advent of digital CCHs has fallen sharply, even powerful single SGPD drifting devices of the Mk3 and Mk4 type against modern torpedoes of the UGST or MTT type and the HAC type MGK-400EM are already ineffective. That is, torpedoes with new SSNs are clearly ahead of SRPDs, and the effectiveness of such SRPGs as C-303 / S (Italy), Mk2, Mk3 and Mk4 (USA), Vist-E and Udar (RF), against modern torpedoes became obviously insufficient and cannot provide reliable protection for submarines.
    It should be specially noted that it is precisely the possibility of fundamentally increasing the noise immunity of a salvo due to the integrated sharing of the torpedo missile launcher and the powerful SAS submarine data that is the key argument in favor of telecontrol. As a result, thanks to telecontrol and new torpedo missile launchers, it becomes possible to significantly reduce the effectiveness of decoys. A particularly problematic issue for the PTZ is the protection against air torpedoes and warheads of anti-submarine missiles, since they are splashed in the immediate vicinity of the protected submarine.
    At the same time, anti-torpedoes alone do not provide a reliable solution to the problem (for example, given the large - up to 8 units - torpedo ammunition on PLO aircraft). What is needed is an integrated system, the integrated use of SRP and anti-torpedo in a single PTZ model. It becomes obvious that new SRSs are needed, and the combined requirements of high power broadband interference and high sensitivity and adaptability to the jamming signal environment are key to creating SRSs that can counteract modern SSB torpedoes.
    We lost both on telecontrol and SRPD, and very much. And not technically, since we have developed very worthy products on this topic (for example, the MG-44 self-propelled simulator or the MG-104 self-propelled torpedo launch device). The problems were organizational: the SRPGs in our country were “lost” between “miners”, “acoustics”, “mechanics”, “calculators”, formally referring to electronic warfare equipment. As a result, the main SSGPs of the USSR Navy's submarines were the drifting instruments GIP-1 and MG-34, the effectiveness of which at the beginning of the 1980's was estimated as extremely low. We did not have anything like the American GNATS SRGD onboard complex, and its home-made analogs like the Proba integrated on-board device used on the C-37 Black Sea submarine only emphasized our entire failure in this direction.
    Nevertheless, a new-generation SRGS has not yet been created in any country, that is, a significant military-technical advantage of the West in this area is actually offset by the development of the CLP torpedoes and SACs of their carriers. And here it is extremely important to lay in the prospective SRGs for the Russian Navy precisely new, modern requirements, and not to borrow long-outdated ideas and concepts in the West, which, alas, some of our specialists are inclined to.
    Today, there can be no effective PTZ without an anti-torpedo. All Russian submarines are required to have them in their ammunition. The task of equipping and developing them is real and should be solved in the shortest possible time.
    EXPORT
    An important issue is the need to include anti-torpedoes in the ammunition of our export submarines, which can dramatically increase their competitive capabilities. Especially given the lack of a full-time serial anaerobic plant today.
    The presence of effective anti-torpedoes in the ammunition dramatically increases the chances of our submarines to succeed in battle, and, accordingly, the export prospects of Russian submarines also increase. At the same time, pressure-tight containers with anti-torpedoes can be placed in outboard launchers, torpedo tubes, and can also be easily installed on a substructure of a submarine or, in the form of a special PTZ module, can be installed in the free volume of a torpedo-loading niche (this is especially true for Amur family submarines).
    In an earlier article by the author on torpedoes of the Chinese Navy (“Torpedoes of the Great Neighbor,” “HBO” from 15.03.19), the issue of exported Chinese torpedoes fell out due to the limited volume. The intrigue is that, given the current military-political situation, it is precisely the Chinese export torpedoes that may be the first to go into battle today (talking about the Pakistan Navy). Moreover, the most interesting question is the torpedo ammunition of the new submarines of the S20 project. It is unlikely that these will be obsolete Yu-3, most likely export versions of Yu-6, Yu-9, Yu-10. In this case, the Indian Navy in the face of Pakistan's S20 submarines will receive an extremely dangerous enemy, especially taking into account the outdated S-303 anti-torpedo defense systems on Indian submarines (including the latest nuclear submarine Arihant) and the significant lag of Indian torpedoes Varunastra (Varunastra) from the new Chinese torpedoes, especially in terms of SSN.
    In recent years, the world has begun to shake significantly, and if during the entire period after the Second World War torpedoes did not receive a serious test of combat (except for individual episodes), it is obvious that this will take place in the near future. Existing GHPs are ineffective against the latest torpedoes, so we must clearly understand that today there can be no effective anti-theft torpedo without anti-torpedoes.
