Great warships

523 Octopus and Bear's Paws Can't Have Both
At the beginning, it was Qin Tao who firmly supported the 14th Institute, but in recent years, the research and development of the 14th Institute has also been progressing rapidly.

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

"As for its weight, after our hard work, the weight of the aluminum alloy frame is now 1.25 tons, plus all the components, the weight is only 3.5 tons, which is lighter than the pre-planned 4 tons."

Xing Wenge faced 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.

"At present, we have completed all the test work of the GT-15000 gas turbine, and it is running smoothly without any accidents, and it is fully ready for shipment." type, that is, the research and development of the GT-25000 gas turbine, the power will be greatly improved, and the fuel consumption will also be reduced.”

Just like Turbofan [-], the current domestic power system research and development is taking the safest path, and they will not consider any improvements first, and first understand the original technology, even if it is backward.

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

Two engines can drive a warship of 25000 tons properly. If it is GT-[-], there is no problem with two engines driving [-] to [-] tons.

"Now, we have all the technical reserves, so next, let's invite the technical team to make an introduction, Mr. Qin, will you come first?" asked the leader above.

Qin Tao nodded: "Okay, let's come first, Gong Yang, please introduce to the big guys."

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

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

Mingzhou Group is a coward!

Then, a warship with a 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 retracted inward. Like the No. 666 frigate built by the Mingzhou Group, it is much more atmospheric than other warships.

The four shields are placed at the four corners of the bridge, which is different from the front, rear, left, and right layout of the American Aegis ship. Instead, they are rotated 45 degrees, which are left front, right front, left rear and right rear. Each shield controls [-] degrees. The airspace seems to have a more appropriate layout.

The bridge is far away from the naval guns. This is because six eight-unit anti-aircraft missile launchers are arranged in this part of the front, which is 48 anti-aircraft missiles.

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

All the anti-aircraft missiles are arranged in front, and there are still many buildings behind.

The ball above the bridge is the guidance radar of the anti-ship missile, and there is also a ball on the top of the mast, which undertakes the guarding task.

The rear of the bridge is the air intake and exhaust port, the exhaust port has been replaced with a circular shape, and there are cooling windows on the outside, which looks a bit unique.

Behind it is the anti-ship missile launcher, and then behind it is the helicopter hangar.

Above the hangar, there is a meter wave antenna device, and there are 730 near-anti-aircraft guns on both sides.

On the whole, the layout is reasonable and very smooth. It is the master of the Mingzhou Group in warships over the years.

Facing this picture, Yang Dawei began to introduce it.

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

Along with his introduction, one after another pictures were constantly 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 cafeteria to eat first, and let's start the other bidding plans in the afternoon?" said the leader who presided over the meeting.

People are iron, food is steel, if you don't eat a meal, you will be hungry!
Everyone stood up and went to the restaurant.

Sun Xuewen came over again.

"President Qin, your design is really 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 pays new year greetings to the chicken." Qin Tao said, "We are bidding rivals! You have been following me like this, do you have ulterior motives?"

Sun Xuewen smiled awkwardly: "Mr. Qin, I want to let you know that our Bincheng Shipyard is sincere. No matter what the result of the bidding this time, it will not affect our friendship."

"Of course." Qin Tao nodded: "Aren't you afraid that once you bid successfully, our Mingzhou Group will trip you up and cause trouble for you in terms of civilian ships?"

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

If the bidding is successful, Mr. Qin will be furious. As long as they don't provide them with Inwa 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 deliver, the compensation is astronomical, and their Bencheng 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, is our Mingzhou Group like this? I, Qin Tao, am a small-hearted person? All the shipyards went bankrupt and merged, believe it or not?"

"I believe, I believe." Sun Xuewen nodded quickly.

"However, I didn't do this. We want to be bigger and stronger, and compete in the world. It's too embarrassing to fight in the nest." Qin Tao said: "You should also see that our Mingzhou Group is not only from China, but also from China. It belongs to the world, and we are developing all over the world. How can we take a fancy to domestic three melons and two dates?"

"Yes, yes, Mr. Qin, I'm treating a gentleman's belly with the heart of a villain." Sun Xuewen blushed.

"Mr. Sun, don't worry. Even if we lose this time, we will continue to cooperate with the civilian ship in a friendly manner. The profits lost on the military ship will be made up from the civilian ship." Qin Tao said with a smile: "And, You have succeeded, and it will save others from gossiping, saying that we operate in secret."

Sweat broke out on Sun Xuewen's forehead, and there was shame in his eyes: "Mr. Qin, our realm is one level behind yours! We are indeed still looking at the country, and you are already on par with the world. You promise that we will work hard to win the bid to beat you on the anti-aircraft destroyer!"

"That's right." Qin Tao looked approvingly: "Beat us, so that you can gain my Qin Tao's respect!"

"Yes." Sun Xuewen was heartbroken.

Mr. Qin is very powerful. If there is any trick to play, the bidding will be no problem. However, Mr. Qin did not do so. Mr. Qin values ​​the domestic air defense destroyer project very much, but Mr. Qin values ​​the development of domestic shipbuilding enterprises more!
This is a noble person, a moral person, and a person who has escaped vulgar interests!

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

Sun Xuewen's heart was warm.

The other people are also very funny. I don't know what Qin Tao and Sun Xuewen are talking about, but I can guess some by looking at their expressions.

Boss Qin is amazing!

It is obviously a competitor, but it is so rare to be able to face it with this attitude. It is both competition and cooperation.

After dinner, in the afternoon, it was the turn of Bincheng Shipyard's bidding proposal.

"Leaders, hello everyone, our shipyard lacks design capabilities, so our warship design drawings are entrusted to domestic ship design institutes to design. An important design idea for the entire warship is to save money as much as possible. to get the best performance."

Save money!

This of course refers to the [-] million people.

Although domestic design institutes also use computer-aided design, when Sun Xuewen reported, he did not use a high-end 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 color of this wall chart is more gorgeous and looks very beautiful.

When Qin Tao looked over, his heart suddenly became excited, and a number jumped up in his mind.

054B!

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

The need for invisibility is also taken into account as a whole. The upper building is retracted inward. Above the bridge in front, the mast is also made into a polyhedron shape. Four small shields are erected on the side of the mast. It should be a special C-band target irradiation radar. On the rear hangar, a rotatable shield was erected, which was a special long-range warning radar.

In the past, Qin Tao had heard Wu Shengli talk about this design concept. At that time, he felt that it was a bit similar to the West. Because the active phased array radar was too expensive for Europeans to use, they built this shrunk version. The domestic technology is becoming more and more mature, and the cost of active phased array radar is getting lower and lower, so a large number of Aegis warships with four-sided phased arrays have been launched.

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

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

The 054 is less than 054 tons, and the [-]A has exceeded [-] tons, which is larger than the displacement of the famous China's first ship.

When it was developed to 054A, it seemed to be mature. However, the technology is constantly developing and the demand of the army is also increasing. Therefore, 054B finally came into being.

Of course, the eyes of future generations are not focused on its rotating phased array radar, but mainly on its propulsion system.

The displacement of this frigate has been enlarged to five or 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, the highest comprehensive electric propulsion system is used, so that there is no need to worry about whether it is diesel-fuel alternating or diesel-fuel cross-linking. When high-speed navigation is required, all the main engines start together. Anyway, they are all driving the generator. All the power is combined and that's enough.

But now, the big guys don’t need to pay attention to the power system. This is nothing else. It must be diesel-fuel alternation, low-speed diesel engine and high-speed gas turbine. It is impossible to combine cars together.

Everyone's attention is of course the air defense system.

"Currently, we want to build a new type of destroyer. The most important problem is that it is expensive. Therefore, we chose a single-sided S-band phased array radar as the main radar. It scans the surrounding sea and air in a rotating manner. In this way, Simplify the four sides into one side, and the cost can be reduced from the original 5 million yuan to more than 1 million yuan." Sun Xuewen's explanation became more and more relaxed: "I think that if we can win the bidding today, then we can defeat Mingzhou What the group wants is not the technology, but the money in the pocket."

The crowd burst into laughter.

Qin Tao is also laughing.

If it weren't for the conversation at noon, Sun Xuewen would never be so relaxed. He would definitely worry about these things, but now, finally, he doesn't have to worry!
He can be generous, even joking. When he said this, he glanced at Qin Tao and saw that Qin Tao was also smiling, and he felt a burst of relief in his heart.

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

We all come from all corners of the country, and we come together for the same goal!Unknowingly, such a sentence popped up in Sun Xuewen's mind, it seems that he has returned to the passionate era, many things have changed, but some things have not changed.

"Because of the way of rotation, 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, since 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 [-] kilometers, which meets our long-range air defense needs."

"Are we conducting research in this area at 14?" a leader asked.

The 14 Haizhixing radar of the 346th Institute has always been centered on the four-sided phased array, and has not engaged in this kind of rotation.

Hearing the question, Mr. Ben said: "We have not conducted research in this area, but our previous radars were all rotating, so there is no problem in the data processing of rotating radars. The shape of the phased array radar antenna changes. , and it will not cause problems, the only problem is that in this way, the refreshing of the target is definitely not as good as that of the four-sided phased array."

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

This is that 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 used four small C-band radars." Sun Xuewen continued: "In this way, after discovering enemy missiles or aircraft attacking, we still have multi-directional anti-saturation interception capabilities. If the leaders can increase the budget, the area of ​​these four small shields will be enlarged, and the detection distance of [-] kilometers can also be achieved. It would be more suitable if the Red Flag Nine can use the active guidance method."

What the navy lacks the most is the area air defense capability. In the past, I didn't even dare to think about it, but I could do multiple-choice questions!
Two solutions, one with comprehensive performance and one with affordable price, how would the Navy choose?
At this moment, even Qin Tao became a little curious.

Mingzhou Group has been preparing for this for a long time, so of course they hope to get orders from the Navy, but Mingzhou Group has no shortage of orders on hand, even if it does not have this warship construction contract, it is irrelevant.

Moreover, although the defeat is glorious, it is not because it is not advanced enough, but because of the high cost, and the high cost has nothing to do with the Mingzhou Group, it is the fault of the 14th Institute.

Thinking of this, Qin Tao has already started to watch this bidding with the mentality of watching the excitement.

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

"The plan of the Bincheng Shipyard is in line with our current situation. We can use a large number of groundwater air defense destroyers with less military expenditure to completely solve our air defense problem." A leader said.

"No, I am firmly opposed!" A person raised his hand: "Our aircraft carrier formation cannot be crippled. In order to fully provide regional air defense capabilities, we must have warships with four-sided phased array radar!"

Qin Tao became more and more interested.

The person who opposed it was Li Yan.

As the first captain of the aircraft carrier, Li Yan made a big splash during the exercise last time, but after the exercise, the aircraft carrier had to continue to be remodeled, so Li Yan had to return to land and continue to practice in Huangdi Village.

This time, a meeting will be held to decide on the construction of the navy's most important air defense destroyer in the future. Li Yan, the captain of the aircraft carrier, is also eligible to participate.

As the captain, he deeply knows that two knives are not qualified, and a qualified area air defense destroyer is necessary, so as 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, two 051Cs were dedicated to guarding our tail because these two warships do not have omnidirectional Air defense capabilities. Now, the Bincheng Shipyard’s plan will inevitably leave some scanning blind spots in front of the warship. On the battlefield, once the enemy flies from the front of the warship, it must not be detected in time.”

There are two masts at the front and back, one must be higher and the other lower, taking care of the C-band irradiation radars on all sides, it must not take care of the long-range scanning radar at the rear.

Only the Mingzhou Group's plan will not leave a blank area for scanning, and there will be no accidental fish that slip through the net.

"Although in formation combat, we can reduce the blind spots through cooperation with each other, but we are not that rich. Many times we have to go out alone with a warship. We need warships with four-sided phased array radar. If it is too expensive And if the number of builds is small, it is better to use 054 to supplement!"

The front-line commander of the navy gave this answer: firmly demand warships with four-sided phased array radar!They are users, 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 only after mobilizing the main force of the three major fleets that it was assembled. Of course, we can't do this in the future.

Look at other American aircraft carriers. When going out, there must be at least two Ticonderoga-class ships next to them!One's own side must have at least two warships with four-sided phased array radar, so that they can feel at ease!

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

The superior leaders are helpless, they have to consider everything.

If the navy wants to go to the ocean, it must have a numerical advantage. The old 051 has come to be replaced!

The 052 destroyer will become the main force in the future, and the number must increase!
Besides, as long as you don't compare it with the United States, look at other countries in the world, which one has this kind of warship?
Well, that is to say, the island country has just launched the second King Kong-class destroyer, which uses the American Aegis system, and there is no shadow in Europe yet. Don't they have the demand for air defense ships?

"Cough, cough." Wu Shengli, who had been silent all this time, finally spoke.

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

"One is quality, 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 talking on paper, first build an experimental warship, after the construction, conduct a lot of tests, and finally determine which one is better, and then build a large number.

Anyway, this kind of thing can't be rushed.

"I think it's okay." The leader who presided over the meeting said, "Let's vote with a show of hands now."

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

"Okay, we will start two models at the same time. The proposal of Bincheng Shipyard is named 052B, and the proposal of Mingzhou Group is named 052C!" The leader who presided over the meeting made a final decision.

This kind of situation has never happened before. Every time Mingzhou Group participates in the bidding, it can almost succeed with an absolute advantage. But now, the superior has fallen into a difficult choice, and two ships have to be started at the same time!
Everyone looked at Qin Tao.

"We accept the navy's arrangement." Qin Tao said: "However, the navy has to order two sets of Sea Star systems with four-sided phased array radar at one time."

two sets?

Two sets is one billion!
The guys are very surprised, the navy gave you an order for one ship, how can you want two sets?Should it be used as a backup?

"Our aircraft carrier is still waiting." After Qin Tao said this, everyone suddenly realized.

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