The US explained how the Chinese "Black Holes" threaten American submarines

20

In the United States continue to analyze the status of underwater fleet The Russian Navy, paying particular attention to individual submarine projects. So, in the center of attention of analysts were the submarines of projects 877 and 636.


The famous "Black Holes", as these boats are called in the American press, can change the naval balance in the South China Sea. So says Caleb Larson, a United States security expert who published an article in the famous magazine The National Interest.

As you know, project 877 submarines, also called “Halibut”, began to be built back in Soviet times, in the 1980s. Sometimes they are also called “Varshavyanka”, since in Soviet times it was supposed to supply submarines to the USSR allies under the Warsaw Treaty Organization. In NATO, submarines of this class were codified as Kilo. The upgraded project 636.3 boats, in turn, were named Improved Kilo.

Until 2006, 24 submarines for the Russian Navy and another 29 submarines for export were built. "Black holes" entered service with the navies of Vietnam, India, Algeria, Iran and China. It is the last buyer who is most concerned about the US military today.

Caleb Larson, having analyzed the technical characteristics of submarines of types 877 and 636, comes to the conclusion that the main advantage of the submarines is its high maneuverability combined with low noise. For example, both types of Russian submarines have a rubberized sound-absorbing coating on the inside, which attenuates the noise arising from inside the submarine.

Interestingly, back in 2018, Chinese media published photos of the 877EKM Halibut submarine. The attentive audience immediately noticed that for some reason the submarine became longer than the classic samples. An insert with a length of 15 meters appeared in the hull of the boat. Then, analysts suggested that an air-independent power plant was placed in an additional compartment. Such an installation increases the stealth of the submarine. By the way, the Chinese Navy used to have submarines with such an installation, known as Type 039A or Type 041.

The project 877 submarine has obvious chances of success precisely in the South China Sea, given its specifics. It is no coincidence that these types of submarines are bought, first of all, by countries with access to the South China Sea and claiming control over it - Vietnam and China.

But while relations with the United States with Vietnam have been developing quite well recently, American analysts cannot say this about China. The PRC is considered as one of the most important probable opponents of the United States, and in the Asia-Pacific region, the Celestial Empire today is the number one opponent.

It is the South China Sea that is the most likely zone of confrontation between the two great powers. The United States seeks to prevent China from gaining full control of the sea, as it links the security of allied Taiwan, considered one of the main pro-American states in the region, along with Japan and South Korea.

American ships patrol the South China Sea, trying to demonstrate their strength to the Chinese fleet. But the Chinese Navy is not far behind: Caleb Larson admits that the maneuverable Black Holes can very effectively withstand the cumbersome atomic submarines of the US Navy if the latter try to launch hostilities in the South China Sea.

Therefore, the command of the US Navy has something to worry about: the Chinese Black Holes will become a very serious adversary for American submarines if the latter try to operate in the South China Sea.

    And it will only increase ...

    - why sculpt a photograph of project 955 if the article is about completely different boats?

      The author proposes an article for discussion rather than a photograph for the article.

    . The general concept of the future naval forces of China was described by the political commissar of the elite Academy of Military Sciences of the People's Liberation Army of China Wen Tsungeng. He said: "China must break the sea blockade by international forces. Only when we break through it can we talk about the rise of the country. And for this rise to be rapid, China must go through the oceans."

    To achieve this goal, China began to develop precisely the submarine fleet. Submarines, according to the Chinese leadership, should be the key to owning the Pacific.

      Ma'am, are you joking or are you seriously sculpting a hunchback !? am
      Look at the shipbuilding program of the PLA Navy ... Where did you see the "boats" there? Why are hinchiki aircraft carriers and destroyers standing if they "develop precisely the submarine fleet"? yes

    Some primitive about the internal rubber coating, which makes a wunderwafel out of boats. Popular Mechanics level. About the insertion is already more interesting, only it is not clear whether it was inserted in Russia or by the Chinese themselves. In Russia, it seems, a plug with VNEU, no?

      insert - fake, like many other things they have - https://topwar.ru/151169-istorija-odnoj-falshivoj-fotografii.html
      and it seems to me (I could be wrong) they don’t have a private university.

    Black hole? I wonder if these boats are really called that way in the American media, or only in our press. It would be nice to quickly put them in full volume to our Far East.

    The noise at low speed of a single-rotor diesel-electric submarine with a working electric motor is an order of magnitude lower than the noise of a single-screw nuclear submarine with a turbo-generator and an electric motor operating, even with natural coolant circulation in the primary circuit of a nuclear reactor. The reason is as simple as a nail - the secondary coolant that rotates the electric generator drive turbine needs a circular pump.

    So the Halibut remain black holes.

      I confirm.

      The nuclear-powered submarine against diesel is virtually no chance. Well, if only everyone at the diesel engine got drunk or there is a clear malfunction like a crooked shaft of some kind of “shnyaga”. You can not hear what does not make noise. And the noise of the fired torpedo will tell the nuclear submarine that he "hit".

      There is such a "thing", called "Teachings on the determination of mutual detection ranges." Two boats move at one point (arriving at the same time) at separated depths and make maximum efforts to detect a "conditional enemy". How much we did not puff up, but as soon as the navigator reported to the emergency control room that we were "at a point" on a request to the acoustic speakers: "Acoustics! Horizon!" - the answer was discouraging: "The horizon is clear!"

      Modern diesel in the hands of a competent crew is a terrible weapon.

    The pump is the main circulation pump. Circular is a saw.
    The contribution of the MCC operation to the general field of the submarine is not so significant when they are operating at low speeds.

      What is the ratio of the noise of a screw-electric motor unit and a turbo-electric-generator-refrigeration-recuperator-pump?

      Even if we assume the intake of cooling water for the second circuit using its high-speed pressure, and not a separate pump.

      You are mistaken, the pump also has a recirculation and circulation pump, the recirculation pump is one thing and the circulation is another, I will not empty out all the heat engineering equipment, wherever there are pumps they are divided into circulation and recirculation, supply and return, the connection circuit of the boiler unit or turbine compartment also have their own pumps, as at gas stations, in the pool, etc. hi

      Not a minus, but before claiming that only the circulation saw is worth a look at other areas of application of pumping equipment!

        There are no recirculation and CIRCULAR pumps in the PTU PLA. There are main circulation pumps (pumping sea water through sections of the main condenser), there are pumps of the condensate-feed system: condensate and feed pumps (starting and working), PTU circulation pumps (for cooling oil and some consumers, for example, steam pressure regulator). Separately, there are pumps of steam ejection refrigeration machines. Their number and names vary, depending on the generation and design of the PLA.

        The report is finished.

          The main one or not, but a circulation or recirculation pump, and you just wrote about it, do you decide whether or not there is a pump? A condensate pump is connected to the turbine, the recirculation pump drives water, the fluid is installed in a circle around the return pipe, the circulation pump is a booster pump

            Your terminology for me, who served in the division of the PLA movement for a decade and a half, sounds crazy.
            Without understanding the question, do not try to teach someone.

              I’m a heat engineer, you are a submariner, but there is one turbine and one turbine piping, I don’t see any reason to argue you have your own concept and principle of operation of the turbine department, I have experience, maintenance and repair and education, the principle of turbine operation is the same everywhere, that at a heat station on a submarine boat, the arrangement of auxiliary equipment may be different, including pumping equipment, evaporators, a safety valve, a check valve, an emergency pressure relief valve, a pressure control valve, a suction pump, it is also a recirculation pump, suction pump, condensate pump, pump low pressure, in a nutshell, a bunch of pumps, so to speak, and not look at the standard picture as a visual aid, but the entire boiler unit in our case, in our case, a reactor with a superheater of the first circuit, if space allows, there may be a second circuit, after the turbine, since paddles are supplied with a steam temperature in the region of 119 ° C and above, a liter of water is converted into steam; It turns out 1700 liters, a dangerous and explosive mixture. hi

    Recently there was a case with our 636.6 and the British multifunction boat in the Mediterranean. Ours went from Black to Mediterranean. So, ours spotted the British, I don’t remember the number, but at a great distance, but our British did not. True, ours at the same time crept at a speed of several knots, but nonetheless. And only then, when our boat had already deliberately gone in the direction of the British, to check when he would count it, then this happened when the distance between them was reduced to a very small
