"Leopard" and other modernized "Pike-B". Development of the fleet of multipurpose nuclear submarines

"Leopard" in the process of withdrawal from the boathouse


The Severodvinsk Zvezdochka Ship Repair Center continues work on the repair and modernization of the K-328 Leopard multipurpose nuclear submarine. The ship, built according to the project 971 "Pike-B", is being upgraded to the state "971M". Recently, the repair work moved to the final stage, and in the near future the submarine will be able to go out for tests, according to the results of which it will return to service.

Long-term modernization


The decision to carry out a deep modernization of the nuclear submarine "Leopard" was made at the turn of the 2011s and 2012s. In mid-XNUMX, the ship arrived at the Zvezdochka CS to carry out all the work required. After the necessary preparation, in May XNUMX the submarine was placed on the slipway in the slipway. Then the dismantling of obsolete units began, the repair of a number of systems, etc.

Unfortunately, the process of repairing the "Leopard" faced various difficulties. The main result of this was the regular change in the planned completion date. Initially, the ship was planned to be delivered no later than 2015, but work is still ongoing and the submarine will be handed over to the customer no earlier than 2021.

The delays were associated with a lack of funding, difficulties in the interaction of enterprises, finalization of the project, etc. In addition, the Zvezdochka Center had to master a new direction for itself: the Leopard became the first ALP of the 3rd generation, which was received for medium repair and deep modernization.


We managed to sort out the difficulties that arose, and by now the so-called. slipway stage of repair. On December 25, the Leopard submarine was taken out of the boathouse and launched. The ship was transferred to the outfitting wall, where the remaining activities will be performed. After that, sea trials will take place, according to the results of which the nuclear submarine will return to the combat strength of the Northern fleet.

Technical details


The modernization project of the multipurpose nuclear submarine "971M" was developed at the SPMBM "Malakhit". The main contractor is the Zvezdochka CA. As developers and suppliers of individual devices, systems and units, 30 companies from different industries were involved in the project.

Reportedly, during the repair, the hull and individual elements of the internal equipment of the submarine were refined. Due to such measures, it was possible to reduce the noise generated and the acoustic signature. General ship systems have been improved, which has increased the operational characteristics and reliability of the boat. Improved conditions for the crew, workers and households.

Project 971M provides for a deep modernization of onboard electronics, affecting almost all major systems. A new combat information and control system is used, communication and navigation facilities have been replaced. The hydroacoustic complex was modernized. All these measures should improve the combat qualities of the ship.


One of the goals of the modernization project is to expand the range of missile and torpedo weapons. The main measure in this context is the use of a modern missile system "Caliber-PL". Missiles of various types and purposes are launched through standard 533-mm torpedo tubes. At the same time, it remains possible to use torpedoes of all modern types with caliber 533 and 650 mm. The smaller caliber ammunition includes 28 units. weapons, for 650 mm vehicles - 12 units.

According to the results of modernization of the nuclear submarine, project 971M retains its original dimensions and displacement. The length of the "Leopard" is still 110 m, the total displacement is less than 12,8 thousand tons. The main power plant based on the OK-650 reactor with one propeller allows speeds up to 33 knots under water. The diving depth is over 500 m.

The project for the modernization of submarines "Schuka-B" received high marks. Officials talk about its high potential. Thus, the management of the Zvedochka Ship Center noted that the modernized nuclear submarine of Project 971M is technically compatible with the modern submarine of Project 885 Yasen.

Fleet-wide


According to the 971 project in its original and modified versions, 15 nuclear submarines were built. The construction of four was canceled after the laying, and the fate of another was decided for a long time. Four nuclear submarines have so far been written off due to moral and physical obsolescence, one has been leased to the Indian Navy, and another will go abroad in a few years. As a result, at the moment in the Russian Navy there are only 9 "Shchuk-B", distributed between the Northern and Pacific fleets.


As the service continued, the Project 971 nuclear submarine underwent minor and medium planned repairs. In 2014, it was decided to carry out a deep modernization of most of the available ships, providing for the replacement of some of the equipment and the introduction of new equipment, incl. modern missile system.

The K-971 Vepr submarine of the Northern Fleet was the first to be repaired and upgraded to the “157M” condition. Work on this ship was completed by the start of 2020, and in August it was handed over to the fleet. At the moment, "Vepr" is the only multipurpose nuclear submarine of the updated project in the combat strength of the Russian fleet. However, new ships are expected soon.

The nuclear submarine K-328 "Leopard" has been under repair since 2011, and for a number of reasons the work was delayed, and the original deadlines were disrupted. Nevertheless, the modernization is almost complete, albeit with a significant delay. In a few months, the boat will be launched for sea trials, and in 2021-22. she can return to service.

According to plans for 2014, four more ships are to be upgraded to 971M. The boats K-461 "Wolf" and K-154 "Tiger" will be repaired for the Northern Fleet. The Pacific will receive the upgraded K-391 Bratsk and K-295 Samara. All of them are already at the shipyards and are undergoing the necessary measures. At the same time, due to the difficulties encountered, the work schedules for individual ships were revised several times. The submarines are scheduled for delivery in the coming years.


K-157 "Vepr" on trials, March 2020

Expected future


At the moment, the Russian Navy has nine Project 971 (M) submarines, and only four are ready to go out to sea for combat service. Other ships are at various stages of repair, and their combat readiness will be restored only in 2021-23. This state of affairs is becoming a cause for concern and requires appropriate action.

Such measures have been developed and adopted, and the situation is changing for the better. This year, the first modernized ship was delivered to the customer, and another one is expected soon. The Shchuk-B grouping in the submarine fleet is gradually being restored, and over the next few years, two-thirds of the submarines of this type will correspond to the latest project.

It is important that we are talking not only about quantity, but also about quality. The ships not only undergo repairs with the restoration of technical readiness, but also receive new equipment and weapons. After repairs, the submarines become quieter, they can detect targets at a longer range, and also hit a wider range of targets using modern missiles.

Thus, the program for maintaining the grouping of multipurpose nuclear submarines is gradually coping with the difficulties that have arisen and, in general, is solving the assigned tasks. The Navy will receive all the required submarines in a new configuration with broad capabilities - although it will take longer than originally planned.

        The main thing for this project is to reduce the noise level, the SAC is very good there, there is a unique system for detecting submarines along the wake.

          Guck was good there in the 80s, normal in the 90s. Already weak. I did not see the system for detecting the potkilvaterny trail on the modernized boat. Maybe they moved where, or maybe they refused. With competent operators (of whom there are almost no), the system works perfectly.
          But the decrease in the level of noise is debatable here. It must be understood that this is not only design solutions, but also a set of organizational measures. And with proper mechanics, the boat can achieve excellent results in noise.

          but the words of pikivedii-Until 2020, it is planned to modernize both ships at the Zvyozdochka CS under the 945M project. On May 14.5.2014, 945, the RF Ministry of Defense signed a contract with the Zvyozdochka enterprise for the modernization of two Project 10 Barracuda multipurpose submarines. After modernization, they will remain in service for another 30.05.1998 years. And further-Withdrawn from the fleet on 2013/4/16.5.2014. In 7.7.2014, he is preparing for repair and modernization to the level of boats of the 2017th generation at the Zvyozdochka CS. As of May 2020, XNUMX, fuel was already being unloaded from the reactor. According to the message dated XNUMX, preparations began for the unloading of spent nuclear fuel. It is planned to return the ship to the fleet in XNUMX. As of XNUMX, repairs stopped, is in reserve. Is Karp
          ... As part of the Federation Council. Repair and modernization will take place after the repair of the "Karp". As of 2020, the repair has been postponed, it is in reserve. Is Kostroma, so the Barracudas either by the end of the 20s may be modernized or disposed of

      It is necessary to oppose something to the shaft of all-fading articles that flooded the VO on New Year's Eve.
      Remember what was not there:
      Torpedoes are not good.
      Air defense of the fleet is not good.
      The ship composition of the fleet is not good.
      SSBN combat duty is not provided by anti-submarine forces.
      Even the equipment of combat swimmers has recently been reached.

      What a strange question? The grandmaster who plays for a long time, of course, foresaw such a development of events in advance, so he could not help ordering a large-scale import substitution immediately after 2004. And the fact that this wise order was not carried out is, obviously, vile enemies and traitors to the motherland tried.

        Or maybe it would be better to move Russia in such a direction (to hang oligarchs, thieves on the trees, to withdraw dengi from the West, to really develop science, education, etc.) that firstly the Maidans were held with the slogans "We want it like in Russia", and secondly import substitution is simply not necessary according to the results of the first?

The usual negative selection in management personnel, which is typical for colonies, since such people are excellent at coping with the main goal - the degradation of a country that has fallen into bondage.

                To whom and what can I offer? In my opinion, the optimal socio-economic system is the global goal of which is the development of the national economy based on high-tech industries. This will be a means for the development of both society and individuals, and one would like to hope that such concepts as "Monarchy" "Russian people" will appear in the constitution. This is short, because you understand that it is somewhat inappropriate to try to develop this topic in the format of an answer to your question.

                  socio-economic system whose global goal is to develop the national economy based on high-tech industries


                  So this system has already been built. And it works for the benefit of those very individual people. Everything is in full accordance with the essence of the national project.

                  It will be a means for the development of both society and individuals.


                  You need to decide. Either the goal of the system is to develop the "economy" or the development of society. If the goal is the first, then the development of the second does not necessarily follow from it. And if the goal is the second, then the development of the "economy" can be neither an end in itself, nor a criterion for the well-being of society.

                    1. This is where it was built? I suspect in the PRC. 2. If only one state existed on Earth, then yes, in the absence of external stimuli, you can spit on everything, confining yourself to solving the food problem, and throw the rest of the resources at least for ballet, at least for building a "death star". And in the current realities, the development of society is problematic without the economy, since such things as independence in decision-making on all internal and external issues depend on its capabilities.

                      Built in the Russian Federation. The goal of the RF project is the development of the national economy, including through industries that are considered high-tech in many countries. Moreover, the national economy in the nation state always belongs to someone specifically. So agitation for the development of the national economy within the framework of a bourgeois project is in fact the same as agitation for the personal enrichment of the owners of this economy. All this has been happening for the last 30 years.

                      And in the current realities, the development of society is problematic without an economy


                      If the economy is not an end, but only a means, this does not mean that the economy is completely ignored. Now economics is the target. As a result, those same "individuals" ignore the real problems of society, arguing their position by the need to achieve abstract economic indicators such as inflation or GDP.

                      I want to say that if there is a desire to develop society, then this is the goal that needs to be set. If a means of support is chosen as the goal, nothing good for society will come of it. Proven on the example of the Brezhnev stagnation and the Russian economy.

    What a familiar workshop in the title photo. Many years have been devoted to work in this boathouse. True, then BDR and BDRM were repaired from it. And "Tiger", "Wolf", "Vepr" flaunted in those years at the pier of Sevmash, preparing to become the basis of multipurpose submarine forces.
    ... How time flies.

    10 years to repair it is beyond good and evil. 9 boats, 4 can go out to sea, so there is one in the sea, rarely two. Well, what is the point in all this?

    The author does not understand what he is writing about !!! Usually difficulties and delays in upgrading arise with the first boat being upgraded !!! Therefore, it is not clear how the delay in putting the boat into operation happened ??? --- the author either does not know what happened or is afraid to write about it !!!
