Chapter 213 Feast

The Sunburner is not a great anti-aircraft carrier weapon. Its range is too short. If you rush towards it, you will die. However, when you meet on a narrow road, the brave will win. You must have this kind of energy.

If we want to improve, we are still far from perfecting the YJ-12. It would be good to imitate it now. Domestic industrial technology has developed very fast. This kind of old-fashioned missile from the 1980s is no longer available in China. It can still be copied.

There should be some hope that a missile boat can rely on its stealth to approach an enemy aircraft carrier and then launch such a big thing. At the same time, in addition to being carried by warships, it can also be used for airdropping, because the carrier aircraft can give it a Enough speed and height, so its range will also increase a lot.

Of course, missiles alone are not enough.

Qin Tao pointed his finger at a cylinder with a spherical top on the bridge, and said to everyone: "That thing is Lao Maozi's famous Mineral-ME radar, nicknamed the Music Station in the West." , we must imitate this radar mapping. In the future, our anti-ship missiles can use it to provide guidance. Even if our Seahawk 8 is modified with a turbojet engine and the range is expanded to one hundred kilometers, it can Use it to guide.”

 “Leave it to us at No. 724!” Someone immediately stood up.

 At present, there is only the Haiying 8 with a range of 40 kilometers in China, so there is not much problem with the guidance of anti-ship missiles. At this range, the warship's own sea search radar can find the target.

But no matter how far away it is, it won't work. Due to the curvature of the sea, enemy warships seventy or eighty kilometers away have already hidden under the sea level visible to our own warships.

 So, when the range continues to increase, you have to find a way.

 General warships use ship-based helicopters. Standing high and seeing far away, as long as the helicopter flies up, it can see further away and reveal the true shape of the target. The helicopter will lock onto the target and also provide relay guidance to the missile.

  However, when the helicopter takes off, it also means that it will appear in the field of view of the opponent's air search radar. If the opponent's anti-aircraft missile range is far enough, the helicopter will also be in danger.

 Lao Maozi's radar adopts a new method, which is the atmospheric waveguide effect that all military fans are talking about. The radio waves emitted by ordinary radars propagate in straight lines when they encounter obstacles and are reflected back. So, does air count as an obstacle?

Under normal circumstances, the reflectivity of the atmosphere for microwaves is very small, but under some special circumstances, under the combined influence of sea surface water temperature, air temperature, cloud height and other conditions, the phenomenon of atmospheric evaporation ducting will occur near the sea surface, and the atmosphere at low sea level will The refractive index will greatly increase for some electromagnetic waves in the 1GHz-100GHz range.

 The sea level and the atmosphere above are closed to form a pipe. In this pipe, qualified radar waves are constantly reflected up and down, and advance alternately. The route traveled by the radar waves is similar to the black thread of a fishing net with large holes. (Gee, this metaphor.)

After Lao Maozi discovered this phenomenon, he conducted a lot of research and then built this advanced radar, which can be said to be unique. In the presence of the atmospheric waveguide effect, its active search radar module has a maximum search range of up to 250 kilometers.

  If it only has this search distance, it is not very unbelievable. What is even more unbelievable is that although it has been reflected many times, its accuracy is still quite high. Its error against a target the size of a frigate is no more than 50 meters!

 So, it is not only a sea search radar, it is also a fire control radar, which can completely transmit the captured data to the missile to complete launch preparations.

The error of fifty meters is nothing at all, because almost all anti-ship missiles are equipped with active radars. When you get near the target, you can turn on the radar to find the target yourself. Needless to say, fifty meters, five hundred meters is nothing.

It can also track 30 targets at the same time, and can even launch fire control-level differential irradiation on multiple targets within visual range at the same time.

In addition to this incredible ability, this kind of radar also has another ability, which is to work passively.

If there is a warship on the opposite side and the radar search is turned on, radar waves will be radiated everywhere and will be received by the passive interception module installed on the Ore-ME radar because it can cover I/G/E/F /D band radar radiation source, in passive mode, it can perform lateral positioning of source targets up to 450 kilometers away.

At this time, it cannot detect the distance of the target, but it can use the "binaural effect" to calculate the distance through the maneuver of the ship. (First drive to a place, measure, then drive to another place, continue to measure, and calculate based on the triangle principle.)

This kind of radar is a timely blessing for the navy of the motherland. Qin Tao’s 051C destroyer is also planned to be equipped with this kind of radar equipment. Now, it can be handed over to relevant units for mapping and imitation. Depending on the situation, the original version or the It doesn't matter if it's a counterfeit version.

 “We promise to complete the mission!” The people in the 724th Institute raised their chests.

“Well, two years at the latest.” Wu Shengli said.

 In terms of electronic technology, China is already better than Lao Maozi, so copying it within two years is not a problem.

At this time, the dismantled mast has been hoisted down. Looking at the back-to-back flat-panel antennas on the mast, Qin Tao said: "This MR710 radar is also a key project that needs to be copied by our relevant domestic units."

"Leave this project to our 14th Institute." Mr. Ben's voice sounded: "We should be the best at this."

 At the meeting in the capital, Mr. Ben was very interested in the plan proposed by Qin Tao. When he saw the back-to-back flat plates on the mast, he was even more surprised.

At that time, he just thought it would be difficult to obtain this kind of radar, but now, this thing is right in front of him. For a research institute like theirs that specializes in radar, it is simply a piece of cake.

“If you say it, it will have to be copied within a year.” Qin Tao said: “Moreover, the area must be larger and the operating power higher, so that its search distance can be farther.”

 The requirements for the 14th institute are of course more stringent.

"After this radar comes out, it should be able to replace our 381-A radar and become the main sea-to-air search radar of our navy for a long time." Wu Shengli said this, and the people present were stunned again. .

 “Can this waveguide technology radar replace our phased array radar?”

“From a technical point of view, it seems to be lagging behind, but from a stability and reliability point of view, there will definitely be progress.” Wu Shengli said: “At present, we have solved the reliability and stability issues first.”

 In fact, there are domestic back-to-back radars, and they have been installed on the No. 132 destroyer for testing. This is the 381A radar. However, it was installed in 1983 and is still under testing because this radar has too many problems.

This radar is of great significance, opening up the phased array era of the motherland navy. Of course, it is not an active phased array radar using T/R components, but a passive phased array radar using ferrite phase shifters. Equipped with frequency synthesizer and frequency agile anti-interference technology, it also has a peak output power of 1 megawatt.

  However, apart from being installed on destroyer No. 132, that is, in the late 1990s, it was installed on destroyer No. 167, and then disappeared without a trace. On the contrary, the domestic top plate copied from Lao Maozi, which is the 382 radar, is used on many warships. Even when the 167 was improved in the mid-term, the 381 radar was removed and replaced with the 382 radar. (Some information said that it was done by the 7th Institute, and some said that it was done by the 14th Institute. They ignored it and put it on the 14th Institute.)

On the way back, Wu Shengli had discussed with Qin Tao many times. The imitation of these radars will allow the motherland's navy to achieve a leap forward development, so this step must be taken!

No matter how poor the navy is, it must squeeze out funds to carry out these projects. Take advantage of this rare opportunity to improve the strength of naval equipment as soon as possible!

The over-the-horizon Ore-ME radar, coupled with this advanced top-plate radar, will allow the Navy to reach the international mainstream level in these equipment fields!

The Shikili missile system at the back has also become a complete set. On this basis, imitating domestic models can greatly improve the navy's air defense level! In the future, it will be paired with Hongqi 9 and Hongqi 7. In this way, short-range, medium-range and regional air defense will be complete!

You have to do it even if you are trying to sell iron!

“Leave the entire Shikili air defense missile system to us.” Experts from the Huating Aerospace Technology Research Institute spoke.

"The flat-plate slot array antenna array and serpentine waveguide feed technology are used here, which reduces the processing difficulty and improves the performance. Lao Maozi is so smart, why didn't we think of it before?" At this moment, Mr. Ben He opened his mouth to interrupt the expert's words and sighed.

In the past, you could only look at photos. Even high-definition pictures taken in the West could not capture specific details. Therefore, no one knew what was weird about this flat-panel antenna. Even based on the shape of its flat-panel, There are also some laymen who think it is a phased array radar.

On fighter jets, the West has begun to use a large number of flat-panel slot antenna arrays, which can effectively improve the ability to radiate electromagnetic waves and increase the performance of fighter radars. However, this requires high-precision processing technology, and the gaps are proportional to the wavelength. Open, there is nothing wrong with it.

Lao Maozi can't do it. The Su-27 is awesome enough, but it still uses a backward inverted antenna, which is an inverted pot lid. The radar weighs one ton, which greatly limits the combat effectiveness of the Su-27.

The Navy also doesn’t have access to flat-plate slot radar antennas, but they used a trick.

They made the waveguide from aluminum alloy material, and opened variable tilt slits in the narrow wall of the waveguide. This waveguide is fed by a power divider made into a serpentine waveguide. By changing the operating frequency, the phase relationship of each unit of the array also changes, and the lobe direction changes accordingly. Therefore, this flat-panel antenna can achieve the scanning effect.

 Smart, so smart!

Only when you get the actual object of Lao Maozi can you analyze the principles inside, and then it will be like an enlightenment.

Although Lao Maozi’s precision machining technology is not as good as that in China, Lao Maozi’s system integration capabilities are really strong!

This serpentine waveguide system with coupling holes is also very simple. It is directly formed by connecting a straight waveguide and a 180-degree curved waveguide. Based on one's own technical level, it can be copied in minutes!

Of course, for a radar, there are many difficulties that need to be overcome. The radar antenna is only one of them. Others include processing systems, high-power transmitters, especially the traveling wave tubes inside, etc. However, , these technologies are in the 14th institute, so it is not a problem. They have already built a big thing like strategic early warning radar. If they copy the gourd, why can't they come up with such a thing?

It's okay to just imitate it. They need to understand the technology thoroughly and then imitate it to improve it, so that the radar can search farther and detect more targets in batches. This will work.

Various tasks are being assigned constantly, and the researchers who are assigned tasks can't wait to go in and dismantle things. Fortunately, most of Lao Maozi's weapon systems are separated, so there will be no chance of disassembly by mistake.

Until dawn, everyone was busy. Qin Tao really couldn't hold on any longer. He looked at Wu Shengli who was fighting non-stop on the side and said to him: "Leader, do you want to take a rest?"

In front of so many people, Qin Tao is still called the leader, and it is not suitable to be called a private title. Even if many people know about their relationship, it will not work.

"You have to remember that you will dismantle what you should dismantle. If you dismantle the wrong things, return them to me. If someone dismantles too many things and wants to hide their personal belongings, don't blame me for being rude!" Wu Shengli said: "The dismantled ones are finished. , put them all aside, and we can’t take them away until we finish counting them.”

 After saying that, Wu Shengli walked out.

“Dad, let me take you to see our new house.” Qin Tao said.

Zhao Ling was also following, and she was in high spirits.

After hearing what Qin Tao said, Wu Shengli nodded: "Huh, I didn't even hold a wedding ceremony. I just went out to travel and get married. During this time, I don't know how many people laughed at me. Fortunately, have you got it back? The lack of good stuff is like blocking their mouths. If they dare to say anything again, I will choke them to death with good stuff."

Wu Shengli is joking. He is very open-minded and will never interfere in his children's affairs. However, he is still looking forward to visiting his daughter and son-in-law's future home.

"By the way, do you want to change Xiaoling's position?" Although Wu Shengli was talking about Zhao Ling, he looked at Qin Tao.

In the past, Zhao Ling was the military representative and often followed Wu Shengli's orders. But now, Zhao Ling and Qin Tao are married. One is the person in charge of the group and the other is the military representative. Although the two of them are still clean at work, they are always gossiped about.

"Okay, Xiaoling can retire from the army, and then be transferred to our shipyard, and she can be my secretary." Qin Tao said: "In the future, when our company is restructured, I will be the president and Xiaoling will be the chairman."

 Normally speaking, this can be considered a normal transfer.

 However, Zhao Ling shook her head.

 She shook her head, making Qin Tao and Wu Shengli stunned.

 “Why, you don’t want to?”

"At present, for our navy, the weakest point is still air defense." Zhao Ling said: "For close point defense, we have Sea Sidewinder, regional air defense, we have the imported S-300 and the domestic model developed by ourselves. , however, there is still a blank in terms of medium-range air defense. The performance of our Hongqi-61 is very poor and cannot meet the future needs of the navy. Now, now that we have obtained a full set of Shikili air defense missile systems, we have also begun to fully imitate them. This anti-aircraft missile, so I want to participate in this project!”

 Zhao Ling's words were resounding, but Qin Tao's face was ugly.

 What, you want to go back to your old job? what about me? I just got married, you want me to be a monk?

I still think that I can go home and sleep with my wife every day in my arms, which is justifiable. It's good for you, but you actually want to leave?

“Xiao Ling, our air defense system is indeed still very weak, but you are not lacking. If you stay at the shipyard, you can also contribute to national defense construction.” Wu Shengli said.

Zhao Ling shook her head: "Dad, you don't know that when I stepped on the Type 956 destroyer for the first time and saw the Shikili anti-aircraft missiles on it for the first time, I already had a strong feeling. As a technician engaged in anti-aircraft missiles, I have a special feeling for this kind of missile. However, the first time I got back only one missile, it was of little reference to us. Now, we have moved After returning to the entire anti-aircraft missile weapon system, the mapping and imitation work will definitely start quickly, and I hope to participate in this project."

Zhao Ling's attitude is very firm: "Even if our regional air defense missile system matures, these missiles can only be used on our domestic large warships. Now our navy has a weak foundation and cannot equip a large number of large warships. After all, Shikili is a medium-range air defense missile that can be installed on our medium-sized warships. For our navy, this missile system is more important. I want to contribute to our navy and build our Navy’s anti-aircraft umbrella.”

"Xiao Ling, since you are so determined, then..." Wu Shengli looked at Qin Tao with hesitant eyes. After all, this matter still depends on Qin Tao's attitude.

"Of course we will support it." Qin Tao said: "Anyway, Huating Aerospace Technology Research Institute is not far from us. Our shipyard also has a branch there. I will go there often in the future."

Qin Tao must support him. He remembers clearly the sparkle in Zhao Ling's eyes when she saw Shi Jili for the first time. Zhao Ling really wanted to do this project, so he couldn't hold him back. .

 Anyway, isn’t it Huating? If he misses his wife, he can drive there at any time.

Zhao Ling’s eyes were filled with emotion: “Brother Tao, thank you for your understanding and support.”

"By the way, Dad, I have some ideas. I'm embarrassed to say it in front of so many people. I'll report it to you alone now." At this time, the three of them continued to walk towards the family building. Qin Tao followed his own The idea came to an end.

"explain."

"Domestic military expenditures are already tight, but there are still many and complex project models. I suggest that we stop all other medium-range missile models under development and make every effort to imitate this Shikili air defense missile system. Instead of thinking about those models ourselves, If it is immature, it is better to imitate the now fully mature model.”

The navy has been struggling with air defense for a long time, and domestic scientific research institutions are also constantly developing it.

In 1966, the Navy's first type of anti-aircraft frigate 053K began to enter the early stage of design. The following year, the development of the supporting Hongqi 61 ship-to-air missile began. However, with the technology at the time, it was not easy to develop land-based air defense missiles. After being put on the ship, it was very difficult to overcome the effects of ship swing, vibration, temperature and humidity changes, and salt spray corrosion.

Coupled with the special background of that era, it was not until 1975 that Hongqi 61 began to be tested on ships. This experiment continued for more than ten years. When Qin Tao traveled here, the Navy was still testing and modifying Hongqi 61. It was finally installed on the 053H2G frigate.

　　It takes ten years to sharpen a sword, but this Red Flag 61 took more than twenty years of hard work.

However, superiors also knew about the problems with the Hongqi 61, so they were also developing follow-up models. In March 1979, the Hongqi 63 medium-low altitude air defense missile project was approved. A rigid requirement for this missile is that it must be able to effectively intercept cruise missiles.

However, after entering the 1980s, as the country opened up and good things were imported from abroad, this missile was also discontinued and began to imitate foreign models.

One of them is the Hongqi 64. This is because the country has introduced the Italian "Aspaid" air-to-air missile. This missile was developed from the American Sparrow air-to-air missile and has excellent anti-jamming capabilities and hit accuracy. Although the country has only introduced It is seeker technology, or decided to develop a new type of medium and short-range air defense missiles on this basis. In 1988, the development of Hongqi 64 officially began.

Although this kind of missile is very advanced, it requires high processing technology after all, which is completely different from the difficulty of imitating Lao Maozi's five major and three crude products.

There is also an imitation of this kind of air-to-air missile, which is the PL-11. Because the imitation was not smooth, both the PL-11 and ground-based air defense missiles were only successfully imitated at the beginning of the new century. As a result, they were not equipped with much equipment. force.

Because by that time, there were already better models in China, and the active radar-guided PL-12 air-to-air missile had also been released, and the PL-11 was outdated. As for the ground-based air defense missiles, they were eventually exported under the name Falcon 60. There is no equipment at all in the country.

 Now, there is no need to waste these funds.

 Another type is red flag 65.

In July 1983, the Navy decided to develop the second-generation Type 052 destroyer. In September of the same year, the development of the Hongqi 65 medium-range air defense missile matching the Type 052 began. Since the country was demonstrating the introduction of Sea Dart missiles at that time, the Hongqi 65 inherited the aerodynamic shape of the Hongqi 4 and absorbed the experience of the Sea Dart in terms of guidance stations and command and control systems.

These plans are not going well. Now that Shijili is here, they might as well stop. However, this will destroy the jobs of many units, and Qin Tao cannot say it on the spot.

"Well, you are right. We will try our best to imitate Shikili and give up everything else. We also need to give an official number to this new anti-aircraft missile system. If it is common to the Air Force, it seems to be It’s Red Flag 16’s turn.”
