Great warships

The financial crisis that occurred in 97 made many people in later generations sigh with emotion how important it is for a decision-maker of an enterprise to have a high enough foresight. People should not be too greedy, otherwise they will die miserably.

The financial crocodiles who have swept away the wealth of several countries fell into the sand when they looted Da Mao. In the end, they could only sit at the negotiating table and negotiate with Da Mao. As a result, Da Mao successfully lost 100 billion US dollars of principal, 200 billion US dollars It also successfully extended the repayment period of many national debts, and sold a large amount of oil incidentally.

The Sanhang Group, it’s unlucky enough. Before the financial crisis broke out, it caught up with the accident of the shipping fleet and suffered heavy losses. Later, it encountered the financial crisis. In order to protect itself, the Sanhang Group abolished many departments one after another and suffered serious losses. The Sanxing Heavy Industry Co., Ltd. was among the first to be laid off.

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

However, the Sanxing Group also got rid of the burden because of this. They still have the electronics industry, and everyone can predict that the electronics industry will become the most profitable industry in the future. development of.

Mingzhou Group was not affected in the slightest, and took advantage of this opportunity to introduce the technology of 256M memory chips from Sanxing Electronics, which was thriving again. BOE, located in the capital, also took this opportunity to introduce a production line for LCD panels, formally entering the LCD market !

A vibrant scene in the east, Qin Tao also continued to be busy. After Wu Shengli came back, he and Wu Shengli went to Bohai Shipyard again.

Bohai Shipyard was one of the 156 key projects in the First Five-Year Plan of the year. When the country began to plan to build nuclear submarines, it took this place as the final assembly plant for nuclear submarines. Since then, Bohai Shipyard has been the only nuclear submarine in China. manufacturing plant.

Therefore, now that Qin Tao and Wu Shengli are going to Bohai Shipyard together, they have only one purpose: to inspect the 093 nuclear submarine that is about to be built here!
If there is no Mingzhou Group, Bohai Shipyard will always eat nuclear submarines, and all kinds of nuclear submarines will continue to be built here in the future, 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 competition every day, and then grab all the warship orders in your hands? Now you are afraid of the pink eye disease of your colleagues gone?"

"Dad, there are too few orders from the navy now. When there are more orders in the future, our Mingzhou Group will definitely allocate some of them 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 the next year's plan, and it happens that the 093 here will be launched next year. The next construction funds will be Used to build more advanced nuclear submarines!"

"We have to make up our minds to engage in 095?"

"Yeah, we originally planned to lease Da Mao's nuclear submarine, but Ah San snatched it away! We actually don't need to rent Da Mao's nuclear submarine at all. We have the technology ourselves, and we will definitely be able to produce a nuclear submarine that is even more advanced than Da Mao!"

Xu Zhengyang followed Qin Tao, and felt guilty for the first time. It was the first time that Mr. Qin's small plan had not been 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 it needs to build more advanced submarines!

The car drove into the shipyard and drove directly into the huge factory building. When the car stopped, several people in the factory building had already surrounded them.

Mr. Peng, Mr. Huang, and Mr. Zhang, the chief designer of the 093 attack nuclear submarine, were 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 people he didn't know and asked.

"President Qin, I'm Li Baotian, the director of Bohai Shipyard." Li Baotian extended his hand enthusiastically: "President Qin, welcome to visit our Bohai Shipyard. We communicated. In the past, I went to your Mingzhou Shipyard twice, but I didn’t see you, and it was your father who received it.”

"Have you been to our factory?"

"Yes, your factory is the most powerful 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 dumb: "What have you reformed?"

"System and management experience, product positioning, etc." Li Baotian said: "Currently, many shipyards in China are introducing your technology to manufacture natural gas ships. Food. Therefore, we decided to focus on VLCC tankers, and our shipyard is currently building a new 40-ton dock, and when it is completed, we will be able to manufacture larger tankers.”

Qin Tao nodded: "That's right, your choice is correct. Now, Sanhang Heavy Industry has closed down and went bankrupt, and the shipbuilding capacity of South Kimchi Country has further declined. Sanhang Heavy Industry used to focus on building oil tankers. Wait until your dock is completed. , just to fill their vacancy.”

"Yes, we think so too." Li Baotian said: "This timing is really good! The financial crisis will definitely pass, and after that, we will have more orders for tankers."

"How about you keep talking?" Wu Shengli said from the side: "Let's read ours, and you talk about yours."

"No need." Qin Tao knew that the father-in-law was urging himself: "We are here to see the submarine this time. As an outsider, I can come to appreciate our most advanced nuclear submarine in China. It is a rare opportunity."

Hearing what Qin Tao said, several old people present were a little embarrassed.

"Mr. Qin, 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 development of nuclear submarines, we It’s already old, and the navy’s future advanced nuclear submarines will 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 80s, China began to develop the next generation of nuclear submarines. At that time, it was only a theoretical research. In 88, the development entered the second stage, and even came up with a model, but the performance is still not satisfactory to the navy.

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

However, everyone in the entire 093 project team knew in their hearts that the performance of this submarine was outdated, and the underwater future of the navy must rely on the Mingzhou Group!
The performance of the diesel-electric submarine produced by Mingzhou Group is already against the sky. When the 095 of Mingzhou Group is launched, the domestic nuclear submarine will definitely enter the first echelon.

They look forward to it.

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

"What you can see from here is the tail of the submarine. We installed a seven-bladed large skewed propeller on it. This propeller is still produced by the Huating Machinery Factory under the Mingzhou Group. It is the most advanced submarine propeller in the country." Mr. Zhang, as the chief designer of this submarine, introduced it to everyone.

The aft section was fully built, including the special propeller, which caught almost everyone's eyes when the propeller was transported and installed.

"The nuclear power system is installed?" Qin Tao is not interested in propellers. After all, the diesel-electric submarines produced by Mingzhou Group also use similar propellers, but they are different in size.

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

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

"Mr. Qin, don't be humble. When we bid, although we were rivals, 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. Yes, there must be advanced nuclear submarines underwater.”

"That's right, our 093 is more of a verification nature. The technology we developed on this nuclear submarine can just match our 095 nuclear submarine." Mr. Zhang said: "Leader Wu, Mr. Qin, where are you going?" Go ahead, at present, we are installing the sideboard sonar array, and when the experiment on our nuclear submarine is mature, it can be used by 095."

Sonar is the submarine's eyes underwater, and it is also crucial for a multi-purpose submarine.

The bow of the boat definitely needs a large bow sonar, which is also the standard configuration of all submarines. However, the detection distance and accuracy it can detect are not very high, and other sonars must be used to cooperate.

For example, towed array sonar, which is released to the rear of the submarine through cables, can even be a few kilometers away to form a sonar array, so that it can detect the sound of longer-distance targets and accurately locate them.

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

It is similar to a towed array sonar, which belongs to an array, so that it can better find the target, but at the same time, it does not need to be towed, as long as it is installed on both sides of the submarine, so, after this sonar was invented, immediately It has become standard equipment for submarines.

If Mingzhou Group wants to develop nuclear submarines, it can only do final assembly. At most, power systems will be added. There are so many subsystems in the submarine, it is impossible for Mingzhou Group to develop all of them. Now, seeing the breakthrough of the sonar system, Qin Tao also Very happy.

Originally, the technology of the sideboard sonar array was proposed by Mingzhou Group, and it was planned to be installed on the 095 submarine. Over the past few years, domestic military technology has developed rapidly!

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

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

Qin Tao looked at the person in front of him in surprise: "Godson computer is 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 ourselves, so there will be no problems .”

In the field of surface warships, electronic countermeasures are very important, but underwater is not so much about it.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, the outer shell of the submarine is an excellent electrostatic shield. Shield.

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

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

"After years of research by our relevant departments, combined with the torpedoes you provided back then, we have finalized the most advanced Yu-6 thermal power torpedo. This torpedo can not only be guided by wire, but also self-guided by active and passive sonar. , is still developing the wake self-guided model, its maximum speed can reach 48 knots, and the maximum range can reach 83 kilometers.” Speaking of these, Mr. Zhang was eloquent: “In addition to these, we also plan to use The torpedo tank launches the latest Eagle Strike [-] submarine-launched anti-ship missile, which enables the submarine to have long-range strike capability."

For a long time, torpedoes have always been the main attack method for submarines. However, with the development of the times and the advancement of technology, the combat power of anti-ship missiles is increasing. Therefore, it is imperative to equip submarines with anti-ship missiles. It must be done.

However, the 093 submarine does not have a special vertical launch compartment, and it still has to use torpedo tubes to launch. This is a big gap with the 095 submarine. When the latter was designed, a vertical launch compartment was specially reserved. Duan, needless to say Eagle Strike 83, even newer supersonic anti-ship missiles can be carried.

"Do you need other guidance methods?" Qin Tao asked.

The range of the Eagle 83 is further expanded than that of the C802, reaching 180 kilometers, and it has further soared to more than 240 kilometers in the later modification. With such a long range, how to solve its guidance problem?
Generally speaking, when the range is [-] to [-] kilometers, the radar of the warship itself cannot detect the target, and a helicopter is needed for relay guidance, which is quite dangerous. The helicopter was shot down, and domestic warships began to popularize the bandstand radar imported from Lao Maozi, just to use a special beyond-the-horizon method to search and attack enemy warships without helicopter guidance.

What about submarines?
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 guiding means, such as relay helicopters, such as satellite reconnaissance data, etc., but if not, you can also use the pre-booked target data to attack. The success rate is relatively high.”

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

Anti-ship missiles have another great benefit: no precise data on the target is required!

Torpedoes will not work, especially direct-flying torpedoes, which must be hit by the active sonar of the submarine to determine the precise data of the target 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. Nearby, it will turn on its own radar and actively search for the target.

It is useless even to get the precise data of the target, because during the time when the anti-ship missile flies past, the target may change its course, and may sail at full speed to try to get rid of the attack. Therefore, almost all anti-ship missiles are active The radar seeker, the longer the range of the missile, the stronger this active search and attack capability must be.Even when a large number of anti-ship missile formations are flying, it is necessary 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 also attack, but the target identification is more complicated."

You can't make a mistake, what if you hit your own surface ship?
In the history of the world's navies, floods washed away at the Dragon King Temple, and the phenomenon of one's own family beating one's own family appeared endlessly!
"Yes, target identification is a big problem. However, thanks to our advanced computer system, we can compare the sound characteristics of various targets, and identify the target warship model by distinguishing the sound." Zhang Lao continued to introduce.

Everyone else has become a foil, only Qin Tao and Mr. Zhang are in constant communication. One of them is the future submarine builder, and the other is the existing submarine builder. Communication between the two parties is inevitable.

Underwater relies on sound, and different ships have completely different sound characteristics!
At this time, Qin Tao had already walked to the side of the submarine, looked at the sonar arrays under construction, and suddenly thought of something: "These sonar arrays are all passive, right?"

Underwater, it is very dangerous to actively make a sound. Most of the sonar will work in passive mode, and even many sonars do not have active mode. Only the sonar at the bow of the boat will be used in the final attack stage or when intimidating the opponent. Use this active mode.

"Yes, both the broadside sonar and the towed array sonar are in passive mode." Zhang Lao said.

"Could it be possible to install an active sound-generating device on top, preferably at the last position?" Qin Tao said.

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

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

In the past, submarines not only had forward-facing torpedo tubes, but also backward-facing ones. In case the rear caught up with the tail, they could launch torpedoes to kill it at any time. However, in modern underwater confrontation, backward launching has already It's getting harder and harder, so the rear-facing torpedo tubes have long since been cancelled.

Qin Tao shook his head: "Of course not, this active sounding device has only one purpose, which is to make a noise similar to that of a 091 submarine."

Similar to the noise of the 091 submarine?
A few people opened their eyes wide and opened their mouths wide. What are they doing?It was Wu Shengli who understood his son-in-law, and quickly figured out what to say: "That's right, what is false is real, and what is real is false. This way, you can confuse the enemy. Yes, if the changes are not big, you can consider it! "

Of course, this change is not big. Domestic submarines are double-hulled, and there is an equipment room between the inner and outer hulls, so that those unimportant equipment are arranged outside, and they will be filled with seawater when they dive.

Therefore, adding a sound generating device inside is actually adding a square dance horn, which is not difficult.

"That's right, that's a good idea!" Huang Lao also reacted: "The sound from this sounding device will completely cover up the noise of our submarine. Usually when we go out to sea and are monitored, they think we are just a modified version of 091. , When we need it, we will turn off the generating device, so that the other party did not sample in advance, there is no data in the database, and they think our submarine is just some kind of sea fish."

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

Now, as long as this remodeled submarine is launched into the sea for sea trials, this situation will definitely not be avoided. So, simply put on a disguise to make the other party think that the noise of their own submarine is still very loud!
Let the other party hear the sound of the underwater tractor and become paralyzed, thus laying the groundwork for the other party.

Yes, this method is very good!
Several people were very emotional, Mr. Qin has many ways, and he found a way to deceive others easily!
"When our 095 submarine arrives, the noise will continue to decrease by an order of magnitude. At that time, we will install such a device to continue to confuse the opponent." Wu Shengli said.

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

"Yes, our plate rolling machine can only roll about eight meters at most at present, and the displacement can only be five or six thousand tons. There is still a big gap between the value required by your 095 nuclear submarine!" Li Baotian said. .
