Chapter 524 You can’t have your cake and eat it too

 At the beginning, Qin Tao firmly supported the 14th Institute, and in recent years, the research and development of the 14th Institute has also been carried out at a rapid pace.

"Currently, through our efforts, we have reduced the length of each T/R component by 5 centimeters, so that the number of such components will further increase under the same size. After target shooting tests at sea, we found that the C-band radar The performance of the C-band response antenna is not enough, so we expanded the area of ​​the C-band response antenna from the original 0.3 square meters to 0.8 square meters, which is an expansion of 2.5 times. In this way, even if the target’s echo is very weak, we can calmly guide it to the missile and successfully solved the problem."

“As for its weight, after our efforts, the aluminum alloy frame now weighs 1.25 tons. With all the components, the weight is only 3.5 tons, which is even lighter than the pre-planned 4 tons.”

Xing Wenge looked at the manuscript and introduced everything.

The Navy is currently bidding for air defense destroyers, so the main introduction is the air defense system. After these introductions are completed, the units responsible for providing ship power systems will also come up.

"Currently, we have completed all the test runs of the GT-15000 gas turbine. It is running smoothly without any accidents and is fully qualified for shipment." Wen Xueyou also came up to give a brief introduction: "We are currently undergoing modifications to it. Type, that is, the development of the GT-25000 gas turbine, the power will be greatly improved and the fuel consumption will be reduced.”

Just like the turbofan 15, the current domestic power system research and development is taking the safest path. We will not consider any improvements first, but first understand the original technology thoroughly, even if it is backward.

 So, what we are currently working on is the low-power version of GT-15000. Even this kind of thing can already meet the needs.

Two engines can drive a 6,000-ton warship perfectly. If it is a GT-25000, there will be no problem with two engines driving a 7,000-8,000-ton warship.

“Now, we have all the technical reserves, so next, let’s ask the technical team to make an introduction. Mr. Qin, do you want to come first?” asked the leader above.

Qin Tao nodded: "Okay, let's go first. Yang Gong, you can introduce it to everyone."

Yang Dawei stood up, walked up with his notebook, and connected to the projection screen.

Other people’s introductions were all straightforward, without even a PPT. As soon as Yang Dawei came up, he started to use high-tech equipment.

 Mingzhou Group is a bastard!

 Then, a warship with an elegant and smooth shape appeared on the projection screen.

 Beautiful, so beautiful!

The entire warship has a stealth design, and the upper layer of the hull is recycled inward. Like the No. 666 frigate built by the Mingzhou Group, it is much more majestic than other warships.

The four shields are placed at the four corners of the bridge. They are different from the front, rear, and right layout of the American Aegis ship. Instead, they are rotated forty-five degrees, namely left front, right front, left rear, and right rear. Each shield controls nine With ten degrees of airspace, the layout seems more appropriate.

The bridge is far away from the ship's guns. This is because six eight-unit anti-aircraft missile launchers are arranged in this part of the front, so there are forty-eight anti-aircraft missiles.

Although Qin Tao has proposed some hot and cold launch methods, these require research and experimentation, so the most common runner launch method is still used, which is very similar to the layout of 054.

 Anti-aircraft missiles are all arranged in the front, and there are still many buildings in the back.

 The ball above the bridge is the guidance radar for anti-ship missiles. There is also a ball on the top of the mast, which is responsible for the warning task.

 Behind the bridge are the air intake and exhaust outlets. The exhaust outlet has been replaced with a round shape and has a heat dissipation window on the outside, which looks a bit unique.

 At the back is the anti-ship missile launcher, and further back is the helicopter hangar.

Above the hangar, there is a meter-wave antenna device, and there are 730 close-in defense guns on both sides.

 Overall, the layout is reasonable and very smooth. It is the master of Mingzhou Group's warships in recent years.

Facing this picture, Yang Dawei began to introduce it.

 From the single-barreled 130mm naval gun at the front, to the four-sided phased array radar on the bridge, and then to the back, we talked for a full two hours, and many details were introduced clearly.

Along with his introduction, pictures were constantly being shown, showing the results of their work.

By the time Yang Dawei finished his introduction, it was already noon.

“Everyone, should we go to the canteen to have a meal first, and we will start the other bidding plans in the afternoon?” said the leader who presided over the meeting.

People are like iron, and food is like steel. If you don’t eat even one meal, you will feel hungry!

 Everyone stood up and headed to the restaurant.

Sun Xuewen came over again.

“Mr. Qin, your design is so beautiful!”

“Mr. Sun, you have been following me like this, and a word flashed in my mind involuntarily.” Qin Tao said.

 “What word?”

“The weasel wishes the chicken a happy new year.” Qin Tao said, “We are bidding rivals! Do you have any ulterior motives in following me like this?”

Sun Xuewen smiled awkwardly on his face: "Mr. Qin, I want to let you know that our Bincheng Shipyard is sincere. Regardless of the outcome of the bidding this time, it will not affect our friendship."

"Of course." Qin Tao nodded: "Are you afraid that once you succeed in bidding, our Mingzhou Group will cause trouble for you in terms of civilian ships?"

 Sun Xuewen was even more embarrassed, that’s what he really meant.

In case the bidding is successful, Mr. Qin will be very angry. As long as they are not provided with Yinwa steel, the natural gas ships under construction at their Bincheng Shipyard will have big problems!

 Once the delivery time is delayed or even unable to be delivered, the compensation will be astronomical and their Bincheng Shipyard will collapse!

 That’s why he kept coming to please Qin Tao.

"I'm very angry." Qin Tao was a little annoyed: "In your eyes, this is what our Mingzhou Group is like? I, Qin Tao, am a coward? If I really want to do something, I can bring domestic All the shipyards went bankrupt, and then they were merged, do you believe it?"

 “Believe it, I believe it.” Sun Xuewen nodded quickly.

"But, I didn't do that. We want to become bigger and stronger and compete in the world. It's too shameful to fight within each other." Qin Tao said: "You should also see that our Mingzhou Group is not only Chinese, but also It belongs to the world, and we are developing all over the world. How can we be interested in the three melons and two dates in China?"

"Yes, yes, Mr. Qin, I am judging a gentleman with a villain's heart." Sun Xuewen blushed.

"Mr. Sun, don't worry. Even if we lose this time, we will continue to cooperate amicably with civilian ships. The profits lost on the warships will be made up from the civilian ships." Qin Tao said with a smile: "Moreover, If you succeed, you will save others from gossiping about us operating in secret."

Sweat broke out on Sun Xuewen's forehead, and there was shame in his eyes: "Mr. Qin, our level is one level behind yours! We are indeed still looking at the country, and you are already looking at the international level. I would like to express my gratitude to you. You promise, we’ll try to win the bid and beat you on the anti-aircraft destroyer!”

"That's right." Qin Tao said with approval: "Beat us, so that you can gain the respect of me, Qin Tao!"

 “Yes.” Sun Xuewen was deeply moved.

 Mr. Qin is very powerful. If there is any trick, there is no problem with this bidding. However, Mr. Qin did not do this. Mr. Qin attaches great importance to the domestic air defense destroyer project, but Mr. Qin attaches even more importance to the development of domestic shipbuilding enterprises!

 This is a noble person, a moral person, a person who has escaped from vulgar taste!

If Qin Tao knew at this time that Sun Xuewen was putting his own evaluation of his father on his head, he would definitely not be in a good mood.

Sun Xuewen’s heart was filled with warmth.

Other people are also very funny. I don’t know what Qin Tao and Sun Xuewen are talking about. Looking at their expressions, I can guess something.

 Mr. Qin is awesome!

It is so rare to be able to face competitors with such an attitude, to compete and cooperate at the same time, even though they are competitors.

 After dinner, in the afternoon, it was the turn of the Bincheng Shipyard bidding plan.

"Hello, everyone, our shipyard lacks design capabilities, so our warship design is entrusted to a domestic ship design institute. An important design idea for the entire warship is to save money as much as possible. down for maximum performance.”

 Save money!

 This of course refers to the 500 million.

Although domestic design institutes also use computer-aided design, when Sun Xuewen reported, he did not use a tall notebook to make a PPT. He used ordinary design drawings.

The Ship Design Institute specially made an extra-large wall chart and hung it directly on the projection screen. The colors of this wall chart are more brilliant and it looks very beautiful.

When Qin Tao looked over, his heart suddenly felt excited, and a number jumped into his head.

  054B!

  If you don’t compare the size, it is almost the same as 054B in my original time and space!

The overall need for stealth is also taken into consideration. The upper building is recycled inward. Above the bridge in front, the mast is also made into a polyhedral shape. Four small shields are erected on the sides of the mast, which should be specialized C-band target illumination radars. On the hangar at the rear, a rotatable shield was erected. It was a specialized long-range warning radar.

In the past, Qin Tao once heard Wu Shengli talk about this design concept. At that time, he felt that it was somewhat similar to the West. Europeans built this reduced version because active phased array radars were too expensive and could not be used. warships, and domestic technology is becoming more and more mature, and the cost of active phased array radars is getting lower and lower, so a large number of Aegis warships with four-sided phased arrays have begun to be launched.

 But now, seeing this rendering, Qin Tao thought of 054B.

 In later generations, the tonnage of warships became larger and larger.

054 is less than 4,000 tons, and by 054A, it has exceeded 4,000 tons, which is larger than the displacement of the famous Chinese First Ship.

 When it was developed to 054A, it seemed to have matured. However, technology continued to develop and the needs of the military continued to increase, so 054B finally came into being.

Of course, the focus of later generations is not on its rotating phased array radar, but mainly on its propulsion system.

 The displacement of this frigate has been enlarged to five to six thousand tons, and four diesel engines are not enough. Therefore, it uses a new generation of high-power gas turbines, plus a combination of two diesel engines.

Moreover, it uses the most advanced comprehensive electric propulsion system, so there is no need to worry about whether it is diesel-fuel alternating or diesel-fuel cross-linking. When high-speed navigation is needed, all the main engines are started at the same time. Anyway, they all drive the generator. All the power is integrated and that's enough.

Now, you don’t need to pay attention to the power system. This is nothing else. It must be diesel-fuel alternating, using the diesel engine at low speed and the gas turbine at high speed. It is impossible to merge the cars together.

 Of course what everyone is paying attention to is the air defense system.

"Currently, we want to build a new destroyer, but the most important problem is that it is expensive. Therefore, we have chosen a single-sided S-band phased array radar as the main radar. It scans the surrounding sea and air by rotating. In this way, By simplifying four sides into one, the cost can be reduced from the original 500 million yuan to more than 100 million yuan." Sun Xuewen's explanation became more and more relaxed: "I think if we can get the bid today, then we can beat Mingzhou. What the group has is not technology, but money in our pockets.”

The crowd burst into laughter.

 Qin Tao was also laughing.

If it weren't for the conversation at noon, Sun Xuewen would never be so relaxed. He would definitely be worried about these things, but now, he doesn't have to worry anymore!

 He can be generous and even joking. When he said this, he glanced at Qin Tao and saw that Qin Tao was also smiling, and he felt relaxed for a while.

 No matter who wins the bid, it is all for the development of our navy. The paths are different, but the purpose is the same.

 We all come from all over the world, come together for the same goal! Unconsciously, such a sentence emerged in Sun Xuewen's mind. It seemed that he had returned to the passionate era. Many things had changed, but some things had not changed.

"Because of the way it rotates, we changed the shape of the phased array radar antenna. It used to be a rectangle of four meters by four meters, but now it is a rectangle of three meters by five meters. This reduces the height and makes it easier to rotate. Easy, because the C-band antenna is removed, the overall number of T/R units is still about the same. The search distance can be maintained at 300 kilometers, meeting our long-range air defense needs."

“Are our 14th branch conducting research in this area?” a leader asked.

The 346 Sea Star radar of the 14th Institute has always been based on a four-sided phased array as the core, and has not adopted this rotation method.

After hearing the question, Mr. Ben spoke: "We have not conducted research in this area, but our previous radars were all rotating, so there are no problems in data processing of rotating radars. The shape of the phased array radar antenna changes. , it won’t cause problems, the only problem is that with this method, the refresh of the target is definitely not as good as the four-sided phased array.”

There are advantages and disadvantages. This can reduce costs, but like other radars, it scans a circle and can continue to scan the target for the second time after returning. It is completely different from the original four-sided shield staring at a certain sky.

 This means you can’t have your cake and eat it too. If you want to save costs, you have to endure the problem of slow data refresh.

 “Old Sun, let’s continue.” the host said.

"In terms of target illumination, we use four small C-band radars." Sun Xuewen continued: "In this way, after discovering enemy missiles or aircraft incoming attacks, we still have multi-directional anti-saturation interception capabilities. If If leaders can increase the budget, the area of ​​these four small shields can be expanded to achieve a detection range of one hundred kilometers. It would be more appropriate if Red Flag Nine could use active guidance."

The most lacking thing of the navy is regional air defense capability. In the past, it was unimaginable that it would be able to do multiple-choice questions!

 There are two options, one with comprehensive performance and one with affordable price. Which one will the Navy choose?

Even Qin Tao became curious at this time.

Mingzhou Group has been preparing for this for a long time, so of course it hopes to obtain orders from the navy. However, Mingzhou Group has no shortage of orders on hand. Even without this warship construction contract, it is irrelevant.

Furthermore, although it failed, it was not because it was not advanced enough, but because of the high cost, and the high cost had nothing to do with the Mingzhou Group. It was the fault of the 14th Institute.

Thinking of this, Qin Tao has already begun to look at this bidding with a lively mentality.

Sure enough, after the introduction of Bincheng Shipyard, the meeting entered a stage of intense discussion.

“The Bincheng Shipyard’s plan is in line with our current situation. We can build a batch of groundwater air defense destroyers with less military expenditure to completely solve our air defense problem.” A leader spoke.

“No, I firmly object!” One person raised his hand: “Our aircraft carrier fleet cannot be lame. In order to fully provide regional air defense capabilities, we must have warships with four-sided phased array radars!”

 Qin Tao is becoming more and more interested.

 The person who objected was Li Yan.

As the first captain of the aircraft carrier, Li Yan stole the show during the last exercise. However, after the exercise, the aircraft carrier had to continue to be renovated, so Li Yan had to return to land and continue training in the wasteland village.

This meeting will be held to decide on the construction of the most important air defense destroyer in the future of the Navy. Li Yan, the aircraft carrier captain, is also qualified to participate.

As a captain, he knows deeply that two swords are not enough. Qualified regional air defense destroyers are necessary to deal with future maritime threats!

"The plan proposed by Bincheng Shipyard is not fundamentally different from our current 051C. In our last aircraft carrier formation, the two 051Cs were specially guarding our tail because these two warships did not have omnidirectional capabilities. air defense capabilities. Now, Bincheng Shipyard’s plan will inevitably leave some scanning blind spots in front of the warship. On the battlefield, once the enemy flies from directly in front of the warship, it will inevitably not be detected in time. "

The two masts at the front and rear must be one higher and the other lower. They take care of the C-band radars on all sides, but they cannot take care of the long-range scanning radar at the tail.

Only the Mingzhou Group’s solution will leave no blank areas for scanning and no fish will accidentally slip through the net.

"Although in formation operations, we can reduce blind spots through cooperation with each other, we are not that wealthy yet. Many times we have to go out to fight with a single warship. We need warships with four-sided phased array radar. If it is too expensive, And if the construction quantity is small, I would rather use 054 to supplement it!"

The front-line commander of the Navy gave this answer: Firmly demanding a warship with four-sided phased array radar! They are users, so of course they have to think about themselves. They don’t care about money.

The last time the aircraft carrier formation went out, it was assembled by mobilizing the main forces of the three major fleets. Of course, it cannot be done like this in the future.

 Look at the American aircraft carriers. When they go out, there must be at least two Ticonderoga-class ships next to them! Our own side must have at least two warships with four-sided phased array radars, so that we can feel at ease!

"However, our strength is limited. The number is too small to meet the needs of the navy. We currently have to build more warships within limited funds!"

 The superior leaders have no choice but to consider everything.

If the navy wants to go to the ocean, it must have a numerical advantage. It’s time for the outdated 051 to be updated!

052 destroyers will become the main force in the future, and the number must be high!

 Besides, as long as you don’t compare with the United States, look at other countries in the world. Which one has such a warship?

Well, the island country has just launched its second Kong-class destroyer, which uses the American Aegis system. There is no such ship in Europe yet. Don’t they have any demand for air defense ships?

 “Cough, cough.” Wu Shengli, who had been silent until now, finally spoke.

"Everyone, I have a proposal." Wu Shengli's words immediately attracted everyone's attention, and everyone looked at him.

“One is quality and the other is cost. We can’t have both at the same time.” Wu Shengli said: “Should we build one each and determine which one is more suitable for us?”

Everyone’s eyes lit up.

 Here, it is purely about talking on paper. Each of them first builds an experimental warship. After it is built, it conducts a lot of tests to finally determine which one is better, and then builds it in large quantities.

 You can’t rush this kind of thing anyway.

 “I think it’s okay.” The leader presiding over the meeting said, “Let’s vote by a show of hands now.”

With a roar, most people raised their hands, and the democratic vote was passed.

"Okay, we will start construction on two models at the same time. The Bincheng Shipyard's plan will be named 052B, and the Mingzhou Group's plan will be named 052C!" The leader who presided over the meeting made the decision.

This situation has never happened before. Every time Mingzhou Group participated in the bidding, it almost succeeded with an absolute advantage. But now, the superiors are actually in a difficult choice, and they have to start construction on two ships at the same time!

 Everyone looked at Qin Tao.

“We accept the arrangement of the Navy.” Qin Tao said: “However, the Navy has to order two sets of four-sided phased array radar Sea Star systems at one time.”

 Two sets?

 Two sets are one billion!

Everyone is very surprised. The Navy has given you an order for one ship. How can you ask for two sets? Do you still need to use it as a backup?

“Our aircraft carrier is still waiting.” Qin Tao said this, and everyone suddenly realized.

Even if the Navy chooses the Bincheng Shipyard plan, Mingzhou Group will not lose. The four-sided phased array radar must be installed on that aircraft carrier!
