Great warships

Chapter 387 The First Domestic Phased Array Radar Antenna
card country port.

Serge was there eagerly waiting.

Finally, the cargo ship Maersk entered the port. When the cargo ship stopped, Serge couldn't help but rushed onto the ship and rushed straight to the lower deck.

The bottom is empty, there is nothing!

Serge's face changed drastically: "What's going on? How did this happen?"

"What's wrong?" Ali was a little puzzled: "Is there any problem here?"

"What about the goods here? What about the goods here?"

"There is no cargo here. All the cargo is on the upper deck. We have already counted it."

Serge could only feel the rumbling in his head.

Be fooled, be fooled!
Ge Guangle also came to the lower deck, seeing the emptiness inside, his face changed drastically.

After spending an extra [-] million U.S. dollars, they just wanted to bring these fighters back. What happened?As a result, the plane disappeared!
"Mr. Serge, we have done what we should do. We hope you can make up for our losses and give us production again."

"Of course it's impossible! We've tried our best this time, and you will bear the losses. We will guarantee the safety of the remaining fifty."

"No, how can you do this?"

Here the two began to quarrel violently in French.

As for the other side, in the aviation base near the Abbas military port, some special goods were stored in the warehouse.

"This is really a perfect operation." Karim said to Qin Tao with emotion: "We..."

"This kind of action can only be carried out once, and the groundwork must be done well to stand on the commanding heights of morality." Qin Tao said: "If it weren't for these Mirage 2000s, I would not have made this plan."

Karim nodded.

Husseini on the side said: "President Qin, what should we do with these fighters?"

"Ah San, Pyramid Country, they are all equipped with Mirage 2000 fighters. Next, you can contact them to see if they are interested in buying." Qin Tao said: "Of course, you can also stock here first, and wait until After this incident has passed for a while, use it yourself."

It's a pity that the Rainbow Country is actually more suitable, but the current Rainbow Country has no such ability at all. A place that has degenerated from a developed country to a developing country has no use for this kind of fighter.

"Yes." Husseini nodded: "We will transfer all the 31 million US dollars we obtained this time to the account of Mingzhou Group. Please transfer it to the J-[-]A development unit."

Anyway, the money came for nothing, so they used it generously.

"Okay, we will do the relevant procedures and contracts in secret. Please rest assured that after this fighter is successfully developed, you will definitely be the second user to equip it. By the way, you should also make relevant preparations here .”

"Understood, we will announce our fighter development plan after a while."

"And those two women."

"Ah."

A few days later, two female corpses were found on the outskirts of the capital of Anxi. The local police reminded foreign friends to be careful not to go to remote places alone, as this is prone to accidents. In addition, they must respect local customs and wear Be decent, and so on.

This thing has just passed.

Qin Tao and Xu Zhengyang had already left Parthia, inspected the progress at Gwadar Port, and when they were planning to return to China, they met with the old Ba's naval officer Mahmoud again.

"The design of your J-31A is very perfect, but after our evaluation, we think that the development of this aircraft is too risky, so we finally decided to continue the Saber 2 project." Mahmoud and Qin Tao said The choice of the Air Force: "This project is the most suitable for us."

The old bus has always been pragmatic, there is no way, there is so much money in the pocket, we must plan carefully, this J-31A sounds very powerful, but there are too many technical difficulties to overcome, and the risk of the project is too great.

After the visit, they finally looked back at the project of Factory 132, and found that the fighter upgraded from the J-[-] has become more and more mature and can fully meet their needs.

Therefore, they stayed in the Land of Abundance, continued to conduct research on this project, and finally signed an agreement for continued cooperation.

When he heard this, Qin Tao showed a satisfied smile on his face. It seems that the Xiaolong fighter will continue to advance steadily, and the old bus will become its largest user. At the same time, as long as the research and development can be completed as soon as possible, then, Before the trend of second-hand F-16 and MiG-29 arrives, it can take the lead in occupying the market and gain the opportunity.

Of course, these are all aviation matters, and they have nothing to do with Qin Tao. Mahmoud just said a few words casually, and then turned to more important topics: "The funds related to our warships have almost been raised. , will be able to officially place an order in the near future, and I hope that you can start work as soon as possible to manufacture this advanced warship for us."

"Of course no problem." Qin Tao immediately agreed, patted his chest: "As long as your funds are in place, we will start working immediately!"

After inspecting the construction site of Gwadar Port for a few days, Qin Tao embarked on the return trip. This trip took another seven or eight days. He was always running outside, and his wife was about to give birth. up.

However, Qin Tao still did not stay at Huating's house, but came to Mingzhou Shipyard.

After repeated tests, the 115 ship has finally completed all the projects, and now it is about to be delivered to the Navy!
On this day, the flags on the 115 ship were flying, just like celebrating a festival.

Captain Wang Qing is the most excited one.

"Mr. Qin, you are here. At the beginning, you participated in our groundbreaking ceremony and sea trials. Now that we have handed over to the troops, it would be a pity if you didn't come!" After meeting Qin Tao, Wang Qing was eloquent. Absolutely.

Qin Tao's memory of the sea trial is still fresh. When he went out to sea for the first time, he found a big shark underwater and kept forcing him away.

"However, a week ago, you still didn't see our sea target shooting test. It was spectacular. When the anti-aircraft missile flew out of the front launch tube, all of us looked like a giant dragon in front of our eyes. It’s like ascending!” Wang Qing continued.

The target shooting test at sea a week ago was not only a finalization test for this warship before it entered service, but also to let some people with ulterior motives know that when it comes to air defense, the navy has made up for its shortcomings!
When the missiles they launched successfully hit the target [-] kilometers away, who else would dare to cause trouble?

The navy is strong, this is confidence!
"Yes, what a pity." Qin Tao said, "By the way, who are the leaders who attended the ceremony today?"

"Of course it's still Wu leader, it's getting late, we have to go there quickly."

"The navy of our motherland has grown from scratch, from small to large. We have experienced decades of ups and downs. In training and fighting, we have written our loyalty to the motherland. Whether it is in the north or in the south, our navy is always going forward !"

"However, it is not enough to rely on our firm will and loyalty. We also need advanced weapons. We need to build a strong navy to protect the seas and territories of our motherland. Now, the ship that will join our navy is the first ship with a displacement of more than A main battleship of [-] tons!"

"At the same time, it is also our navy's first professional regional air defense ship. Its service will fill the gap in our navy's air defense and become a symbol of our strength!"

At this moment, Qin Tao was also very excited.

That's right, this is the Navy's first major warship with a displacement of more than 3000 tons. The previous 051 with a displacement of more than 4000 tons and the 052 with a displacement of more than [-] tons will become history!And the area air defense capabilities it provides are lacking in other warships.

"Now, I announce that No. 115 is officially named Shenyang! The flag presentation ceremony will be held below!"

The military band was playing the accompanying music, and the guard of honor was advancing. The one walking in the front was Wang Qing with an excited face. He took the military flag from Wu Shengli and walked towards the warship.

Warship No. 115 officially joins the Navy!

There was a humming sound, and the huge warship left the port of Mingzhou for the last time, preparing to go all the way north to the port where it needed to berth. There were well-dressed sailors standing in front of and behind the warship.

On the outfitting pier not far away, ship No. 116 is still undergoing final outfitting work. It won't be long before ship No. 116 will also be launched into the water, undergo sea trials, and then join the navy sequence.

"Taozi, how do you feel at this moment?" Wu Shengli asked Qin Tao after the warship left.

Looking at the leaving warship, Qin Tao's face was full of longing: "I seem to see a super aircraft carrier with a displacement of [-] tons sent away from us."

With a displacement of [-] tons, a super aircraft carrier!
These words made Wu Shengli feel complicated.

Where is the aircraft carrier of the motherland?Wu Shengli is full of expectations, while Qin Tao has always firmly believed that that day will definitely come.

"At that time, our stealth carrier-based aircraft will be deployed on the aircraft carrier and take off through electromagnetic catapults. No matter where in the world, our people are in danger, the navy will arrive. Our leadership When a situation arises, the first sentence is, where is our aircraft carrier."

"Yeah, I don't know if I can see this day coming." Wu Shengli said with emotion: "Taozi, you did a great job on this trip to Anxi. Many people are saying that only you can Do something like this."

"A lot of people?" Qin Tao was taken aback.

Wu Shengli smiled, what is Qin Tao worried about?Leak?Of course, it is impossible for many people in my mouth to leak secrets.

"With a huge fund of 31 million U.S. dollars this time, the J-[-]A project will continue. Many people are curious, you are a shipbuilder, but you have pushed in the aviation industry. Moreover, the technical indicators are still the highest .”

"It's not for our navy." Qin Tao said, "Dad, next, shall we go back to Huating?"

"Well, when we pass the 14th school, let's go in and have a look."

Qin Tao nodded. Of course he knew what the 14th Institute was doing. It seemed that the domestic phased array radar had made great progress.

At this time, while talking, the two had already walked to the welding workshop of the natural gas ship. It can be seen that there are obviously many more people in the workshop than before.

When Cong Ju saw Qin Tao approaching, she immediately greeted him enthusiastically.

"President Qin."

"Well, come by and see, why are there so many people here?"

"President Qin, you won't forget, right? Didn't we have an agreement with Huating Shipyard to help them train Inwa Steel's welders?"

Qin Tao suddenly realized: "Yes, of course I remember, these workers seem to be able to operate proficiently."

"Well, according to our previous agreement, these workers have to work for us for several months, so that they can master their skills more proficiently."

Qin Tao nodded, very satisfied with the arrival of these free laborers.

"Our first natural gas ship with our own patented technology is the last box left. It is expected that this natural gas ship will be delivered to customers by the end of this year."

Qin Tao continued to nod: "This is a new beginning for us. Let me know in advance when the time comes, and I will definitely come here to attend the delivery ceremony."

Cong Ju smiled and didn't answer, obviously he didn't trust Qin Tao's words.

Qin Tao said he would come, so he will definitely come?It may not be somewhere in the world by then!
After leaving the production workshop of the natural gas ship, Qin Tao walked around in other places, and finally boarded the car with Wu Shengli.

By the time we reached the 14th, it was already evening.

"Would it be inappropriate for us to come here at this time?" Qin Tao said, "I think it's time for dinner."

"Let's go and have a look first." Wu Shengli insisted.

So, when several people put on their white coats and walked in after cleaning, Qin Tao was surprised to find that although it was lunch time, no one was eating here, and they were still busy working!

What surprised Qin Tao even more was the huge 4-meter-by-4-meter flat plate standing in their laboratory.

This flat panel is made of aluminum alloy as the skeleton. At this time, a dozen technicians in white coats are standing on the scaffold, installing something for this flat panel. Each of the small honeycomb-like units is small and exquisite. The T/R assembly is accurately fixed in place.

"Old Ben, have you started building this first shield?" Qin Tao asked in surprise.

Hearing his question, Mr. Ben, who was directing the installation work there, turned his head and looked at Qin Tao and Wu Shengli with a smile on his face.

"Yes, we are doing the final installation work. After the installation and debugging are completed, we can start the experiment on land first."

This is also the first active phased array radar in China!

Wu Shengli looked at the tablet with excitement in his eyes.

"Old Ben, this project of yours is what the navy is looking forward to the most! As long as the test passes and the four-sided shield is produced, our navy can start building the first professional air defense ship with four-sided phased array radar!"

Although No. 115 is already in service, it is not professional after all. It has only one side of passive phased array radar, and it has to rotate to complete the whole airspace search. Because it is blocked by the bridge, there is still an air defense blind spot in front.

It would be great if the four-sided phased array radar could be installed on a warship.

"Yes, Mr. Ben, our Mingzhou shipyard has already begun to design a special anti-aircraft warship based on our 346 radar and Hongqi [-] missiles. We are ready for everything and only owe Dongfeng."

Wu Shengli glanced at his son-in-law and knew that there was something to be said.

Special anti-aircraft warships, they have already designed it, just waiting for bidding!
This time, are there any units competing with them?
I am afraid that those units will retreat in spite of the difficulties!

After all, 051C, 054, and the warships manufactured for the Oriental Pearl Tower were all designed by Mingzhou Shipyard. Now, no one dares to question the strength of Mingzhou Shipyard. To take over.

Old Ben smiled: "Mr. Qin, it seems that we will have to cooperate closely in the future."

"Of course, Mr. Ben. According to our design plan, the layout of the four-sided phased array radar is different from that of the American Ticonderoga class, and similar to their Arleigh Burke class. Your antenna must also follow this plan. to optimize."

The Americans were the first in the world to build this kind of professional air defense ship. However, the layout of the four-sided phased array radar is very particular.

The Ticonderoga-class cruiser uses a simple layout of front, rear, left, and right, each responsible for a [-]-degree fan-shaped area. It seems to be very suitable, but in fact there is a problem: when the warship is shaking back and forth in the sea, the four shields radiate The outgoing electromagnetic waves may not be able to fully cover the entire airspace.

To put it simply, if you swing left and right, the shield on the left may not be able to sweep up the sea, and the shield on the right may not be able to reach the top of your head if you turn down.

Therefore, when it came to the Burke-class destroyer, the installation position of the four-sided phased array radar became left front, right front, left rear, right rear, and it was not placed vertically, but with a certain inclination angle. In actual use, the layout scheme is the most suitable.

Of course, our Aegis warships also need to be arranged in this way.

Old Ben nodded: "We originally planned to determine the advantages and disadvantages of various layout schemes during the land test. Now, since Mr. Qin has designed the warship according to the layout of the Burke class, it shows that this layout should be more appropriate. We will also optimize based on this arrangement."

While communicating with each other, while continuing to watch the progress of the installation, Qin Tao couldn't help but said, "When you install this phased array radar, can't you install it flat?"

Standing four meters high in this way, scaffolding is required. If it is installed flat, the big guy can just lie on it.

Facing this idiot question raised by Qin Tao, Mr. Ben was very patient.

"If it is installed flat, it means that some of us need to step on it. The aluminum alloy frame is deformed, or the installed components are stepped on to change the position. For debugging, it is a disaster. .”

"Also, we not only need to install on the front, but also need to wire on the back. The current operation is done by people on both sides."

Only then did Qin Tao realize that he walked to the back, and sure enough, there were many people busy there.

"Everyone is working so hard, and you have to endure hunger. I can already hear someone's stomach growling."

"There is no way. The installation of our phased array radar requires a high degree of cleanliness. It will take time for everyone to put on and take off their clothes and undergo dust-free treatment." Ben Lao said: "Everyone will get off work for a while, wait until seven or eight o'clock , we will get off work."

"Okay, then let's wait, and then go have dinner together." Wu Shengli said.

Seeing the technicians working hungry, Wu Shengli was also very moved.

"How many units are there on this antenna array?" Qin Tao asked.

At the time of the bidding, it was said to be more than 4000, but the exact number is not clear.

"Specifically, there are 4768 pieces." Ben Lao said: "Among them, one-third is gallium arsenide, and two-thirds is bipolar silicon, which is a compromise between performance and cost. After this For the production of phased array radar, we are also constantly exploring and improving the production process of gallium arsenide, and when it is actually mass-produced in the future, it may use a higher proportion.”

Bipolar silicon is easy to produce, but its quality is low and its performance is poor. Gallium arsenide is difficult to process, but its performance is high. At Qin Tao’s suggestion, a compromise was made.

"Yeah, we have to quickly mature this technology. Not only the navy's warships need it, but the radar of our navy's carrier-based aircraft also needs to advance to active phased array radar."

Not only warships need to use radar, but also fighter jets. The demand for fighter jets is even stronger, especially the J-31A.

"You also need fighter jets?" Elder Ben frowned.

"What, can't you?"

"If it is to be used by fighter jets, then the existing T/R components are still not enough. Either use a newer generation of gallium arsenide or gallium nitride, so that the volume can meet the use of aircraft, especially the latter, which should be the most suitable .”

"What is gallium nitride?" Wu Shengli was curious.

"Gallium nitride is a compound of nitrogen. This nitrogen is a gas molecule with a molecular weight much smaller than that of arsenic. Speaking of the atomic volume of gallium nitride, it is only half that of gallium arsenide, and, more importantly, the nitride Gallium is an extremely stable compound with high hardness and a melting point of 1700 degrees Celsius. After the device is made of gallium nitride, it will not deform when stepped on, and it can work in a high temperature environment of 800 degrees Celsius. The breakdown voltage of gallium nitride is respectively It is several times and tens of times that of silicon bipolar tubes and gallium arsenide, which can easily increase the power density of the array."

Speaking of these, Old Ben was in high spirits.

"Take our phased array radar as an example. If the components inside are replaced with gallium nitride, even if the number remains the same, the search distance can be increased by at least 1.7 times, that is, to achieve a search distance of [-] kilometers and to explore ballistics. Missiles are fine. Even at close range, they can directly concentrate energy to burn through the electronic equipment of anti-ship missiles!"

Wu Shengli opened his eyes wide, so awesome?

"However, this technology is very difficult. At present, even in the United States, the second-generation or third-generation gallium arsenide is used in airborne phased array radar, and gallium nitride is still under research and development. Here, Due to lack of funds…”

"The problem of funding, let's find a solution." Qin Tao said: "When the funds are in place, we 14 all don't have enough technical strength to conduct research on gallium nitride?"

Think about the aircraft carrier of electric bombs in the future, paired with J-31A, and then cooperate with this phased array radar, how exciting!Therefore, Qin Tao couldn't wait.Just follow the path of the international joint fighter, and use other people's funds to develop your own technology!
"We can't do it ourselves. We need to cooperate with domestic material experts. However, as long as we have funds, other things will not be a problem!"

"Okay, then let's make a deal."
