Chapter 626 The 093 submarine is about to be launched

 The financial crisis that occurred in 1997 made many people of later generations lament how important it is for a company's decision-makers to have high enough foresight. People cannot be too greedy, otherwise they will die miserably.

The financial giants who had swept away the wealth of several countries failed when they looted Mao. In the end, they could only sit at the negotiating table and negotiate with Mao. As a result, Mao successfully lost 10 billion US dollars of principal and 200 million US dollars. With interest rates of US$100 million on national debt, they also successfully extended the repayment period of many national debts, and also sold a large amount of oil along with it.

The Three Bank Group was unlucky enough. Before the financial crisis broke out, it caught up with the accident of the transport fleet and suffered heavy losses. Then it encountered the financial crisis. In order to protect itself, the Three Bank Group eliminated many departments one after another and suffered serious losses. Three lines of heavy industry were among the first to be laid off.

In this way, only Hyundai Heavy Industries is left among the three shipbuilding giants in the South Kimchi Country!

However, Sanhang Group has also shed its burden. They still have the electronics industry. Moreover, everyone can predict that the electronics industry will become the most profitable industry in the future. Sanhang Group is going into battle lightly, and perhaps there will be even greater success in the future. development of.

The Mingzhou Group was not affected at all and took this opportunity to introduce the technology of Sanxing Electronics' 256 MB memory chip. It was once again prosperous. BOE, located in the capital, also took the opportunity to introduce an LCD panel production line and officially entered the LCD market. !

 There was a vibrant scene in the east, and Qin Tao continued to be busy. After Wu Shengli returned, he and Wu Shengli went to Bohai Shipyard.

Bohai Shipyard was one of the 156 key projects in the First Five-Year Plan. When the country began to plan to build nuclear submarines, it was used as the final assembly plant for nuclear submarines. From that time on, Bohai Shipyard was the only nuclear submarine in the country. Manufacturing plant.

 So, now Qin Tao and Wu Shengli are going to Bohai Shipyard together for one purpose: to inspect the 093 nuclear submarine that is about to be built here!

Without the emergence of the Mingzhou Group, Bohai Shipyard would have always relied on nuclear submarines, and various future nuclear submarines would continue to be built here. But now, 093 is probably the last nuclear submarine they built.

 In the car, Qin Tao was still a little worried.

“Dad, what will those people think of me? Will they drive me out with a broom?”

Hearing what Qin Tao said, Wu Shengli smiled: "Why, there are times when you are afraid? Don't you shout about competition every day and then grab all the warship orders? Now you are afraid of the pink eye of your peers Already?"

"Dad, the Navy's orders are too few now. When there are more orders in the future, our Mingzhou Group will definitely allocate part of it to our brother factories." Qin Tao said.

Wu Shengli nodded: "Yes, our current funds are still not sufficient! However, we have included the construction of nuclear submarines in next year's plan. It just so happens that the 093 here will be launched next year. The next construction funds will be Used to build more advanced nuclear submarines!"

 “Are we determined to do 095?”

“Yes, we originally planned to lease Dal Mao’s nuclear submarine, but Asan snatched it away! In fact, we don’t need to lease Dal Mao’s nuclear submarine at all. We have enough technology ourselves, and we will definitely be able to build a nuclear submarine that is more advanced than Dal Mao!”

Xu Zhengyang followed Qin Tao, feeling guilty for the first time. It was the first time that Mr. Qin's little calculation was not reported to his superiors. However, there was no need to report or not, after all, the results had already come out.

 The navy wants to build submarines and more advanced submarines!

 The car drove into the shipyard and drove directly into the huge factory. When the car stopped, several people in the factory had already gathered around.

 Mr. Peng, Mr. Huang, and Mr. Zhang, the chief designer of the 093 attack nuclear submarine, are all here, welcoming the visitors from the navy. When they saw Qin Tao, everyone was very polite.

“Who is this gentleman?” Qin Tao looked at one of the unknown people and asked.

"Mr. Qin, I am Li Baotian, the director of Bohai Shipyard." Li Baotian extended his hand enthusiastically: "Mr. Qin, welcome to our Bohai Shipyard for inspection. We are all colleagues in the shipbuilding industry and we should have communicated with each other long ago. We communicated. I went to your Mingzhou Shipyard twice before, but I never saw you. It was your father who received you."

“Have you been to our factory?”

“Yes, your factory is the best in the industry, how can we not learn from it?” Li Baotian said: “Every time we go to inspect, we will have a deep feeling, and we will carry out some reforms after we come back.”

Qin Tao was a little dumbfounded: "What have you reformed?"

"System and management experience, product positioning, etc." Li Baotian said: "Currently, many domestic shipyards are introducing your technology to manufacture natural gas carriers. However, we have analyzed that with the swarm of natural gas carriers on the ground, there may not necessarily be any Food. Therefore, we decided to focus on VLCC tankers. Our shipyard is currently building a new 400,000-ton dock. Once completed, we will be able to manufacture larger tankers."

Qin Tao nodded: "Yes, your choice is correct. Now, Sanhang Heavy Industry has gone bankrupt, and Nanjingguo's shipbuilding capacity has further declined. Sanhang Heavy Industry used to mainly build oil tankers. When your shipyard is completed, , which can just fill their vacancies.”

“Yes, we think so too.” Li Baotian said: “This is a great time! The financial crisis will definitely pass, and after that, we will have more oil tanker orders.”

“How about you continue?” Wu Shengli said from the side: “Let’s look at ours, and you can talk about yours.”

"No need." Qin Tao knew that his father-in-law was urging him: "We are here to see the submarine this time. As an outsider, it is a rare opportunity for me to come and appreciate the most advanced nuclear submarine in our country."

 Hearing Qin Tao say this, several old people present were a little embarrassed.

"President Qin, please stop joking." Mr. Zhang said: "Our nuclear submarine was already outdated when it was developed. Although it has been produced, many of its performances are outdated. In the research and development of nuclear submarines, we We are already old, and the navy’s future advanced nuclear submarines still depend on you!”

The 091 and 092 nuclear submarines only solved the problem of availability, and their performance has long been outdated. Therefore, in the early 1980s, China began to develop the next generation of nuclear submarines. At that time, it was just a theoretical research. By 1988, the development had entered In the second stage, a model was even built, but the performance was still not satisfactory to the navy.

Until a few years ago, the Navy finally started bidding for nuclear submarines. The project Mingzhou Group participated in the bidding was too advanced and was suspected by many people to be too advanced. It turned to theoretical research, and the 093 submarine entered the fast lane and began to be officially built.

However, everyone in the entire 093 project team knows that the performance of this submarine has fallen behind, and the navy's underwater future must rely on the Mingzhou Group!

The performance of the diesel-electric submarines produced by the Mingzhou Group is already incredible. When the 095 of the Mingzhou Group is launched, it will definitely make the domestically produced nuclear submarines enter the first echelon.

 They are looking forward to it.

However, the child is still good for himself. At this time, the navy came to inspect and they were also very happy.

"What you see here is the tail of the submarine. We have installed a seven-blade large side-inclined propeller on it. This propeller is produced by the Huating Machinery Factory, a subsidiary of the Mingzhou Group. It is the most advanced submarine propeller in China." Mr. Zhang, as the chief designer of this submarine, introduced it to everyone.

 The tail section has been completely built, including the special propeller. When the propeller was transported and installed in place, it attracted almost everyone's attention.

“Has the nuclear power system been installed?” Qin Tao was not interested in propellers. After all, the diesel-electric submarines produced by Mingzhou Group also used similar propellers, but the size was different.

"Yes, it's all installed, a ten-megawatt reactor." This time it was Mr. Peng's turn to speak: "The power of this reactor is really not high. When the Mingzhou Group builds a new submarine, a 150-megawatt nuclear reactor, Only then can the submarine have a good speed!"

“Everyone, you always say this, which makes me a little embarrassed, as if the next nuclear submarine must be produced by our Mingzhou Group, which is not necessarily the case!” Qin Tao said.

"Mr. Qin, please don't be modest. Although we were rivals when we were bidding, we admired the design of your nuclear submarine very much. Only your Mingzhou Group can design such an advanced nuclear submarine. We already have an aircraft carrier. Well, there must be advanced nuclear submarines underwater."

"Yes, our 093 is more important for verification. The technology we developed on this nuclear submarine can be used to support our 095 nuclear submarine." Mr. Zhang said: "Leader Wu, Mr. Qin, you go Go ahead, currently, we are installing the side sonar array, and when the experiments on our nuclear submarines are mature, we can use it on the 095."

 Sonar is the underwater eyes of a submarine. For a multi-functional submarine, sonar is also crucial.

 The bow definitely needs a large bow sonar, which is also standard for all submarines. However, its detection distance and accuracy are not very high, and other sonar must be used to cooperate.

For example, towed array sonar, which is released behind the submarine through cables, can even be several kilometers away to form a sonar array, so that it can detect sounds from targets at longer distances and accurately locate them.

  However, the towed array sonar needs to be released and recovered, which may be inconvenient to use in some special situations. Therefore, advanced submarines have a third type of sonar: side sonar.

It is similar to a towed array sonar. It belongs to an array, so that it can better detect targets, but at the same time, it does not need to be towed. It only needs to be installed on both sides of the submarine. Therefore, after this sonar was invented, it was immediately used It has become a standard feature of submarines.

If the Mingzhou Group wants to build a nuclear submarine, it can only do the final assembly, plus the power system at most. There are so many subsystems of the submarine, and it is impossible for the Mingzhou Group to develop them all. Now, seeing the breakthrough in the sonar system, Qin Tao also Very happy.

Originally, the side-side sonar array technology was proposed by the Mingzhou Group and was intended to be installed on the 095 submarine. The project was just a pre-research project. Unexpectedly, the brother unit was making rapid progress and actually developed it. It seems that this In the past few years, domestic military technology has developed rapidly!

"Our supporting brother units have also worked hard." Qin Tao said: "This kind of side sonar array requires powerful data processing capabilities to be effective, right?"

“Yes, we have installed a Godson computer on this submarine. We use Godson to perform data calculations, and the performance is hundreds of times higher than the previous system.”

Qin Tao looked at the person in front of him in surprise: "Loongson computers are used on it?"

"Yes, in order to improve the processing performance of submarines, it has become a common practice to use powerful commercial computers on submarines. Anyway, there is no need to worry about electromagnetic interference underwater. Moreover, Godson is produced by us, so there will be no problems. .”

In the field of surface warships, electronic countermeasures are very important, but underwater there is not so much emphasis on them. The underwater world and electromagnetic insulation are the world of sonar. Even if an electromagnetic bomb is detonated, it will not affect the underwater submarine. Needless to say, just the shell covering the whole body of the submarine is an excellent electrostatic Shield.

"Mr. Qin, your Mingzhou Group has played a great role in the development of our military industry!" When introduced here, Mr. Zhang was very emotional: "Without your Mingzhou Group, we would never have used it. These are advanced equipment.”

 Speaking of advanced equipment, what did Qin Tao think of: "What are the main weapons used on this 093 submarine?"

"After years of research by our relevant departments, combined with the torpedoes you provided back then, we have now finalized the most advanced Yu-6 thermal power torpedo. This torpedo can not only be wire-guided, but can also be self-guided using active and passive sonar , we are currently developing a wake-guided model with a maximum speed of 48 knots and a maximum range of 50 kilometers." Speaking of this, Mr. Zhang kept talking: "In addition to these, we also plan to use The torpedo tank launches the latest YJ-83 submarine-launched anti-ship missile, giving the submarine a long-range strike capability."

For a long time, torpedoes have always been the main means of attack on submarines. However, with the development of the times and the advancement of technology, the combat power of anti-ship missiles is becoming more and more powerful. Therefore, it is also inevitable to equip submarines with anti-ship missiles. It must be done.

However, the 093 submarine does not have a dedicated vertical launch cabin section, and still has to use a torpedo launch tube to launch. This is different from the 095 submarine. When the latter was designed, a vertical launch cabin was specially reserved. Duan, not to mention the YJ-83, can even carry newer supersonic anti-ship missiles.

“Do you need other means of guidance?” Qin Tao asked.

The range of the YJ-83 is further expanded than that of the C802, reaching 180 kilometers. In later modifications, it further soared to more than 240 kilometers. With such a long range, how to solve its guidance problem?

Generally speaking, when the range is seventy or eighty kilometers, the warship's own radar cannot detect the target, and helicopters are needed for relay guidance. This is quite dangerous. Once the opponent has a long-range area air defense missile, it can attack it at any time. After the helicopter was shot down, domestic warships began to popularize the music station radar imported from Lao Maozi, in order to use a special over-the-horizon method to search and attack enemy warships without the need for helicopter guidance.

 What about the submarine?

 How to solve the problem of target guidance when submarines attack long-range targets?

Hearing Qin Tao's question, Mr. Zhang nodded and said: "It would be best if there are other means of guidance, such as relay helicopters, satellite reconnaissance data, etc. However, if not, it can also be based on pre-binding Target data to carry out attacks. The success rate is still relatively high."

Their 093 submarine uses a variety of radars. The bow radar only has a search range of tens of kilometers, but the search range of the towed array sonar and side sonar is much longer, and it can detect one or two hundred kilometers away. water target.

Anti-ship missiles also have a big advantage: they do not require precise target data!

Torpedoes will not work, especially direct-flying torpedoes. The active sonar of the submarine must be used to hit the target, and the precise data of the target can be determined before attacking. For anti-ship missile attacks, you only need to bind the data of the sea area where the target is located, and wait until the anti-ship missile flies to the target. If it is nearby, it will turn on its own radar and actively search for targets.

Even if you get accurate data about the target, it is useless, because during the period when the anti-ship missile flies over, the target may change its course, and may sail at full speed to try to get rid of the attack. Therefore, anti-ship missiles are almost all active. Radar seeker, the longer the range of the missile, the stronger its active search and attack capabilities must be. Even when a large number of anti-ship missiles fly in formation, they also need to have the ability to identify targets and distribute attacks.

Qin Tao nodded: "It is best to use satellites, but even without them, a single submarine can still attack. However, target confirmation is more complicated."

You can’t hit the wrong one. What if you hit one’s own surface ships?

In the history of the world's navy, floods washed away the Dragon King Temple, and the phenomenon of one's own family beating one's own family occurred one after another!

"Yes, target identification is a big problem. However, thanks to our advanced computer system, we can compare the sound characteristics of various targets and determine the model of the target warship by identifying the sounds." Mr. Zhang continued.

 Other people have become foils. Only Qin Tao and Mr. Zhang are constantly communicating. One of them is a future submarine builder and the other is an existing submarine builder. Communication between the two parties is inevitable.

 Sound is what matters underwater, and the sound characteristics of different ships are completely different!

At this time, Qin Tao had already walked to the side of the submarine, looking at the sonar arrays under construction, and suddenly thought of something: "Are these sonar arrays passive?"

Under water, it is very dangerous to actively make sounds. Most sonar will work in passive mode, and many sonar even do not have active mode. Only the sonar on the bow of the boat will use it in the final attack stage, or when intimidating the opponent. Use this active mode.

“Yes, the side sonar and the towed array sonar are both in passive mode.” Mr. Zhang said.

“Can we install an active sound device on top, preferably at the last position?” Qin Tao said.

 Active sound emitting device? Also installed at the end? Everyone present was confused.

"Mr. Qin, do we need to have the means to attack the enemy backward?" Huang Lao asked.

In the past, submarines not only had forward-facing torpedo launch tubes, but also rear-facing torpedo tubes. If there was a tail behind, they could launch torpedoes at any time to kill it. However, in modern underwater confrontations, rear-facing torpedo tubes have become It is getting more and more difficult, so the rear-facing torpedo tubes have long been cancelled.

 Qin Tao shook his head: "Of course not. This active sound device has only one use, which is to make noise similar to the 091 submarine."

 Similar to the noise of the 091 submarine?

Several people opened their eyes wide and opened their mouths. What are they doing? It was Wu Shengli who understood his son-in-law, and he quickly figured out something: "Yes, what is imaginary is real, and what is real is imaginary. In this way, you can confuse the enemy. Yes, if the changes are not big, you can consider it!" "

This change is of course not big. Domestic submarines are all double-hulled. There is an equipment room between the inner and outer hulls, so that unimportant equipment can be arranged outside and will be filled with seawater when diving.

 So, adding a sound-generating device inside is actually just adding a square dance speaker, which is not difficult at all.

"Yes, this is a good idea!" Mr. Huang also reacted: "The sound emitted by this sound-generating device will completely cover up the noise of our submarine. When we go to sea and are monitored, they think we are just a modified version of 091. , when needed, we will turn off the generating device, so that the other party does not take samples in advance, has no data in the database, and thinks that our submarine is just a sea fish."

The underwater confrontation is silent, but very exciting. Although the main confrontation is between the United States and the Soviet Union, almost every time the domestic 091 submarine goes to sea, it will be followed by others.

Now, as long as this modified submarine is launched for sea trials, it will definitely not be able to avoid this situation, so we might as well use a disguise to make the other party think that our submarine is still very noisy!

Let the other party hear the sound of the underwater tractor and become careless, thereby laying the groundwork for trapping the other party.

 Yes, this method is very good!

Several people were very moved. Mr. Qin had so many methods and easily found another trick to trick others!

“When our 095 submarine arrives, the noise will continue to be reduced by an order of magnitude. At that time, we will install such a device to continue to confuse the opponent.” Wu Shengli said.

"Yes, the technical reserves of our 095 submarine are becoming more and more abundant. We have a suitable nuclear reactor and even a pump-jet propeller. The quietness of the submarine will continue to improve. However, I don't know if we have large-scale coils." Trigger? If there is no such thing, a submarine with a larger displacement cannot be built!" Mr. Peng asked with some worry.

"Yes, the plate bending machine we have here can only roll up to about eight meters at present, and the displacement can only be five or six thousand tons. There is still a big gap between the values ​​required by your 095 nuclear submarine!" Li Baotian said .
