Chapter 409 850mm Vertical Launch Tube

 Having finished talking about the power system at the back, let’s move on to the front.

“Next, let’s talk about other layouts, the location of the control tower, the layout of the torpedo room, etc. I won’t go into details. I will just make a few requirements.”

 Kvasa nodded.

The displacement of 8,000 tons and the VM-5 reactor are almost the same as their 945 nuclear submarine. Therefore, there is almost no need to change the latter. Various vibration and noise reduction technologies can also be used. The pump-jet propeller at the tail It was a difficult point, but it was left to Petrov to solve.

 Now, they are focusing on the layout in front.

“In the middle of the hull, there need to be 12 vertical launch units with a caliber of about 850 mm, directly from the top to the bottom. I think it should be better to be next to the power cabin.”

　His words confused everyone.

“President Qin, are we going to build a multifunctional attack nuclear submarine or a ballistic missile nuclear submarine?”

 “Of course it’s an attack nuclear submarine.”

“Then why carry a vertical launch unit?”

In everyone’s impression, attack nuclear submarines only need torpedo launch tubes, while only ballistic missile nuclear submarines need vertical launch devices.

“Could it be a cruise missile attacking a nuclear submarine?”

When hearing this question, Qin Tao nodded with satisfaction: "Yes, that's it! Since the displacement has been enlarged to 8,000 tons, of course we need to add some of our unique cabin sections. These twelve launchers No, it’s used to launch cruise missiles.”

Generally speaking, nuclear submarines are divided into two types: attack nuclear submarines and ballistic missile nuclear submarines. However, Lao Maozi also has a third type, which is a cruise missile nuclear submarine, which is similar to the Oscar-class big guy, specially used to carry anti-ship missiles to attack the enemy. aircraft carrier formation.

“So, is this launch tube used to launch anti-ship cruise missiles to attack enemy aircraft carrier formations? What anti-ship missiles are planned to be stuffed in it?”

Qin Tao smiled: "I don't know."

have no idea?

That’s right, Qin Tao really doesn’t know now. Because various advanced anti-ship missiles, cruise missiles, and even anti-ship ballistic missiles have not yet come out!

Qin Tao is just preparing for a rainy day. It is useless now, but it will definitely be useful in the future. They are designing it now. When they get approval and start construction, it is estimated to be a few years later. It will be in service for 20 to 30 years, at least it will be 2020. That At that time, all kinds of advanced weapons came out, but it turned out that submarines could not carry them!

Submarines can also launch anti-ship missiles. Now domestic submarines are trying to launch YJ-81 anti-ship missiles. This missile is small in size and can be launched from a 533mm torpedo tube, so it seems unnecessary. of.

 But later, with brand new missiles, you will find that the torpedo launch tube is not thick enough!

The diameter of 850 mm mentioned by Qin Tao is also well-founded. The 055 of later generations used this kind of launch tube, which can stuff a lot of things. Qin Tao tentatively set the diameter at 850 mm. In the future, even the Dongfeng 21 My younger brother can also fit in. This thing is a real aircraft carrier killer!

The original Dongfeng 21 has a diameter of 1.4 meters. Later, in order to be used on the 055, it was made thinner and the range was reduced to about a thousand kilometers. But it doesn’t matter. This kind of big killer can be used as a deterrent. Enemy aircraft carrier formation.

It is used on 055 and of course it must be used on submarines.

 Get it ready now so you don’t have to modify it when it’s time to use it.

(I saw a statement saying that the turtle-back shape of the 093 is not the hanging hair or the towed sonar, but the integrated nuclear reactor that cannot be placed. I was shocked. I visually inspected the position and it should be one-fifth of the hull. The second place, the three-fifths of the volume at the back, is it all the nuclear reactor and power system? Or does it mean that the crew lives on the **** of the submarine?)

Countless people are shocked and cannot use it. Mr. Qin, if it cannot be used, then what are you talking about here?

 However, no one dared to question it. Since Qin Tao had said it, they had designed it according to this plan.

"Mr. Qin, do you have any other requests?" Kvasa asked. In the last action, Kvasa had completely admired Qin Tao. Now, he will listen to whatever Qin Tao says. Maybe now I don’t understand, but it will definitely be useful in the future.

"There is nothing else for the time being. Let's design according to these ideas first. Everyone, show your true skills and let your superiors see the strength of our third design office!"

 Qin Tao is full of expectations.

As for the hat on the conning tower, it can be changed later. These are small things. The key is to design the main body of this submarine first.

From this day on, everyone has entered into intense work. They have become proficient in using computers to draw, which is convenient for design and modification. However, their workload is still very heavy.

 Kvasa has long had a plan to modify the already mature Type 945, so the final appearance of this submarine will still be very similar to the Type 945.

 In the first two days, Qin Tao helped coordinate in the design office, but on the third day, something new happened.

“Mr. Qin, there is a foreign customer who wants to order high-strength steel from us.” On the phone, Zhang Jinxi, the person in charge of the steel plant, was a little excited: “This is the first time our steel has gone abroad!”

Now, the steel from Mingzhou Steel Plant has been used in many ways. Not only Mingzhou Group itself uses it, but also its brother units will order it. However, when it comes to exporting, it has never been done before.

Although Qin Tao plans to open a new shipyard in Rainbow Country, this matter is still being promoted, the process has not been completed, and they have not officially taken over. The export of steel products has not yet started.

Of course, the batch of melting and remaking the steel of the submarine's pressure hull, and then using it on the Novorossiysk that was being refitted does not count. This project is secret and cannot be announced to the public, otherwise Ah San will not be too impatient.

"Okay, congratulations." Qin Tao didn't pay much attention to it at first. This kind of trivial matter was just to give him good news, and his subordinates could handle it themselves.

“Yes, we are also very happy. Our steel plant can also directly export and earn foreign exchange. They asked us if we have 921A grade high-strength steel.”

 When he heard this sentence, Qin Tao immediately became vigilant.

921A is a special code name. This steel is only used on domestically produced nuclear submarines! Most people have no idea how powerful its performance is.

It seems that the last action made some people nervous. They wanted to find out more information, so they decided to come here!

 After all, the steelmaking technology of Mingzhou Steel Plant is already far ahead in the country, so they are being targeted.

This customer is a fake person who comes to buy steel, but a real person who wants to get information!

 “Then how did you answer?”

“I said, 921A steel is nothing. The steel we produce now is much more advanced than that kind of steel!”

 “Well, hold them still, don’t say anything, and wait for me to pass.”

Putting down Big Brother, Qin Tao had a smile on his face: "Zhengyang, let's go and fool people!"

Xu Zhengyang’s eyes also lit up.

When you go out with Qin Tao, no matter what you do, you will be rich and colorful. However, if you stay in the design office, Xu Zhengyang will be depressed. Although he also knows some technical knowledge, it is only superficial. Now he watches these all day long. The technician was working on the design, and he felt like his head was going to explode.

 Deceive people, deceive whom?

 You will know it naturally when you arrive.

 Mingzhou Iron and Steel Works.

With a smile on his face, Zhang Jinxi looked at the guests in front of him: "Everyone, I am very honored to be recognized by you. Our President Qin will be here soon. When the time comes, I will ask him to communicate with you in person."

"We at Irvine Shipyard are also looking forward to cooperating with you. This time, we need the strongest steel plate. We are here because of your reputation, and we hope to get what we want from here." A middle-aged man named Lesk said.

 “Yes, thank you for your trust.”

 While Zhang Jinxi was patiently going around in circles with the other party, Qin Tao finally came over.

"Mr. Qin? It's a pleasure to meet you. You are well-known in the shipbuilding industry. In particular, you have begun to expand globally and have also acquired shipyards in the Rainbow Kingdom. Our Irving Shipyard may one day be owned by you. acquisition.”

  Irving Shipyard?

 Qin Tao understood immediately. On the surface, this shipyard belongs to the Maple Leaf Country, but in fact, the Maple Leaf Country has to listen to the United States in the south no matter what matters. This is also their consistent policy.

This time, when they came over, the mastermind behind them was about to emerge.

"Really? Then I also look forward to such a day." Qin Tao's words made the whole conversation go away. They were just being polite, so why should Qin Tao take it seriously?

“Mr. Qin, this is Leske, an engineer from Maple Leaf Country’s Owen Shipyard. They are currently building a special ship and want to find the strongest steel in the world, so they found us.” Zhang Jinxi smoothed things over.

"Yes, we need to build an icebreaker. We hope that the strength of this steel is as high as possible." Lesk said: "You can even produce Invar steel and build warships. We believe that you must have the most advanced of steel.”

“Yes, of course we have advanced steel, such as 921A steel, it’s just child’s play in front of us, but it’s very expensive!”

“Really? How expensive is it?” Lesk asked Qin Tao.

 “Five million dollars a ton.”

What Qin Tao said almost made Zhang Jinxi scream out in fright, five million US dollars per ton?

Ordinary marine steel plates cost three to five thousand yuan per ton, and warship-grade steel plates cost about ten or twenty thousand yuan. Not counting Invar Steel, the most expensive high-strength steel plate they produce costs two hundred thousand yuan per ton. tons, even if sold to a brother unit, it will not exceed 500,000 tons per ton.

What now?

 Now it actually costs 5 million, or US dollars?

Mr. Qin is too brave to ask for it, right?

Sure enough, when Qin Tao said this, Leske was a little nervous: "Mr. Qin, isn't the price of this kind of steel plate too expensive?"

"Expensive? Then you buy American steel, HY80. It seems that there is HY100 now. These steels are also high-strength steels. Why bother to buy them from us?"

Lesk gritted his teeth: "Then, we hope to get a sample and test the strength. If it meets our needs, we will order again."

Qin Tao shook his head: "Of course not. We will issue a quality report for the steel. We can guarantee that the steel we produce can fully meet your requirements. However, we do not provide samples, and the minimum price is ten tons."

 If you don’t provide samples, do you still sell starting from ten tons?

 Mr. Qin said this, the other party should just stand up and leave, right? Zhang Jinxi is a little worried. If this news gets out, his reputation may not be good, right?

  You can’t discredit the group, as it will have to compete in the international market in the future!

Sure enough, Leske stood up and said, "We cannot agree to your conditions. The price is too expensive and you haven't even given us samples for testing."

“Then please, after all, two thousand megapascals of steel cannot be bought just anywhere.”

 What, two gigabar?

Zhang Jinxi felt his heart beating faster. After all, he had been working hard and down-to-earth since he became the head of the Mingzhou Steel Plant. He had never gone out with Qin Tao. Therefore, his understanding of Qin Tao was limited to the occasional visit. During a meeting at the Mingzhou Shipyard, I never heard of Qin Tao talking about trains.

 Does a two-gigabar steel plate exist in this world?

 Zhang Jinxi, a master steelmaker, thought it was impossible.

After all, even the United States currently uses deck steel on aircraft carriers of only 800 MPa, and what is currently being studied is said to be 1,000 MPa. The most advanced steel currently produced by their Mingzhou Steel Plant is about 700 MPa, and the output is still very low. They are still continuing to research.

Who would have thought that Mr. Qin actually said two thousand megapascals?

  (I checked some information and said that we have developed 2200 MPa ourselves. It feels like bragging.)

Leske was also moved.

 Two gigabar of steel? His subconscious reaction was also impossible. However, without this high-strength steel, how could the submarine being pursued at sea dive to a depth of 600 meters?

Furthermore, there is obviously still room for that depth. To be able to dive to such a depth, one must either use titanium alloy or super steel.

  Could it be that the steel technology here is already more advanced than that in the United States?

  If it is of this level, then five million US dollars per ton is acceptable. After all, the performance is comparable to that of titanium alloy!

"This level of steel is also very important to our country and is absolutely not allowed to be exported. However, we are a private enterprise and must consider survival and make money, so I came here in person. "Qin Tao said: "However, if we want to complete this business, we have to make several transfers to make it safer. If we sign an agreement with you, it will be under the name of another company."

“Mr. Qin, I would like to ask you to do a test for me. As long as I can see the test results, we are willing to buy ten tons.”

Anyway, it’s the employer behind the scenes who provides the money, and he’s just an errand boy.

Qin Tao nodded: "Of course, but please be mentally prepared. Once the deal is concluded, we will never admit that we have done such a deal."

Lesk nodded: "Okay."

 Mingzhou Iron and Steel Plant, Inspection Department.

Any steel plant will set up a special inspection department to inspect various raw materials and also to test various finished products.

Of course, the testing equipment does not need to be large. For example, this yield strength testing machine. The small machine is a desktop computer. It has a column on the left and two clamps to clamp the object and then test it. There is an operating device and an operating device on the right. Display interface displays various measurement data.

The equipment at the Mingzhou Steel Plant is all large. This yield strength testing machine is directly stuck on the ground. It is as tall as a person and can sandwich a desktop-sized steel plate in the middle to conduct experiments.

Xu Zhengyang pushed the trolley with the steel plates for testing on it until it was in front of the testing machine.

"The surface of this steel plate..." Lesk looked at the shiny surface with some curiosity.

 “Galvanized steel plate.” Qin Tao introduced simply.

 Zhang Jinxi opened his eyes wide.

What galvanized steel plate? This is obviously a titanium alloy plate, okay?

This thing was originally curved, but after being placed on the bending machine and operated back and forth a few times, it was flattened.

Since it has been left for a long time, a layer of oxide has appeared on the surface of this plate, which looks similar to a galvanized plate. As for the edges, I don’t know how they were treated, but they look a bit like ordinary steel plates.

Leske was going to step forward and touch it with his hands, but was stopped by Qin Tao: "I'm sorry, I can only look at it, not touch it."

Keske could only give up.

 The steel plate was clamped up. The experiment officially begins.

Lesk's eyes were fixed on the screen, the numbers on it were beating rapidly.

 Seven hundred, eight hundred, one thousand!

 One thousand megapascals, this is already the most advanced steel that the United States can produce!

 And this special steel plate in front of me is still as stable as a mountain!

　One thousand three, one thousand fourteen, one thousand five…

Leske's eyes were filled with surprise. He witnessed a miracle!

 The steel plates produced by Dongfang are actually the most advanced in technology!

 One thousand six, one thousand six hundred two, one thousand six hundred three…

 Click!

At this moment, the test sample made a sound and a crack appeared on the surface.

 The machine stopped running.

"I'm very sorry. The quality of our current batch of steel plates is not very stable." Qin Tao said: "However, this piece should be a defective product. Other steel plates, even if they do not reach 2,000 MPa, can Reaching 1890 MPa.”

  Qin Tao was also a little embarrassed when he said this.

The cowhide is not blown, the train is not pushed, there is no 2 GigaPascal steel plate, and there is no 2 GigaPascal titanium alloy plate. This old Maozi's titanium alloy plate specially used for nuclear submarines can only support the current situation. degree.

“Forget it, the quality is unstable. You’d better not buy it. Let’s just pretend that nothing happened.” Qin Tao shook his head.

Who would have thought that Leske insisted at this time: "No, Mr. Qin, we are willing to buy it!"

Even if it does not reach two thousand megapascals, it is only more than 1,600 megapascals, which is still powerful enough! After they buy it back and do some research, maybe they can promote the advancement of their own steelmaking technology?

It is normal for the quality of this kind of advanced steel to be unstable. If the test really reached two thousand MPa, then Lesk really suspected that there was something wrong with the machine. Now, the fact that the data did not meet the standard made him convinced!

“No, no, we can’t sell substandard steel. Wouldn’t this destroy our own brand?” Qin Tao continued to shake his head.

"No, no, you can sell it. Didn't we say, sign under another name? I will never come to trouble you. We can accept the steel we purchase, no matter what it is."

“What’s the point of this? Our price will not change again. After all, the cost of this kind of steel is not low.”

 Zhang Jinxi is a little messy.

　　Has he never seen such a scene before? His outlook on life and the world will be completely overturned.

 The test is not up to standard and the data is unqualified. This kind of fraud will be strongly despised by customers. Now, the other party keeps asking to buy it?

 This is really Zhou Yu's attempt to defeat the enemy.

“Then the contract must add such a clause. If the test fails to meet the requirements, the claim will be waived.” Qin Tao said.

“Yes, you can! Don’t worry, we are not that kind of rogue company.”

There is a kind of company in this world that specializes in buying fake and shoddy products and then filing lawsuits to make money in this way. At this time, Lesk immediately thought of Qin Tao's concerns, and patted his chest and promised: "However, I hope to buy these ten tons of steel immediately."

"Of course, no problem. As long as the funds are transferred to our designated third-party account, you can take the steel away immediately. You can handle the import and export procedures yourself."

 “Okay, I’ll contact you now.”

 Leske left with his men, leaving Zhang Jinxi who continued to be confused.

“Mr. Qin, where did we get this kind of steel?”

“What steel material is similar to this sample in the warehouse?” Qin Tao asked.

“We don’t produce many galvanized sheets. It seems that only a batch of civil steel sheets are galvanized sheets.” Zhang Jinxi said.

 Galvanized sheets are not used in shipbuilding. Anyway, after the construction is completed, the outside has to be painted. Galvanized sheets are expensive and rarely used.

 “Then let’s take this batch.”

"However, the yield of this batch is probably only about two hundred."

"Two hundred is two hundred, it's not low anymore. They have promised that even if the requirements are not met, they will not make any claims. However, the appearance must be similar. Come on, let's take a look first. If it doesn't look like it, we will think about it later. Think of ways to."

 Zhang Jinxi felt a chill in his heart.

Looking at Zhang Jinxi's coy look, Qin Tao smiled: "What's wrong? Can't stand it? Do you know the real purpose of their coming?"

Zhang Jinxi shook his head. He just thought it was strange. Icebreakers don’t need this level of steel. What else did they say about 921A steel? Wait, could it be?

“They want to pry into our domestic R&D and production capabilities of advanced special steels by purchasing steel, and then pry into the performance of our military products.” Qin Tao said: “We cannot be soft on this kind of opponent.”

“I just received news that at present, in various large steel plants in our country, foreign customers have purchased high-strength steel.” Xu Zhengyang added on the side.

 Zhang Jinxi nodded, and he finally stopped hesitating: "Mr. Qin, I thought wrongly."

“Mr. Qin, after they get it, what if they find another place to test it and find that there is something wrong with this batch of steel?”

“They will definitely find a way to transport it out as soon as they get it. Don’t worry.”

Five million to a ton, ten tons is 50 million. Two hours later, the money arrived. Then, Leske asked to see the steel, transported it to the port by truck overnight, and went through the export procedures.
