Great warships

Chapter 884 World-Leading Technology

The power system and cost determine the displacement, and the displacement will determine the number of weapons and equipment. After all these are finished, it seems that the prototype of 055 is ready to come out: small aspect ratio, four gas turbines, all-electric propulsion, front and rear vertical hair.

Next, it seems that there are only a few details left.

"Our four-sided phased array, I think we should just use the 052D directly. It adopts liquid cooling, which has more advanced performance, stronger power, and good endurance. We will add a meter wave radar to the tail." Wu Shengli said. .

In his eyes, it seems that it only needs to be transplanted from the 052D, after all, they are already mature.

Qin Tao shook his head: "Dad, if this is the case, then our 055 is just a simple enlarged version of 052. For this [-]-ton warship, it is considered a waste."

waste? More than 100 vertical hair units are also called waste?

The big guy was a little puzzled.

"Taking our 052D as an example, it needs a lot of radar equipment, not only the electronic systems such as the 4-sided 346A active phased array radar and the 517B air-to-air warning radar, but also the 366-type over-the-horizon sea search radar. , 1290 navigation radar, 344 fire control radar, etc., as well as various data antennas, our bridge is full of various radar equipment, which does not look simple at all."

Everyone opened their eyes wide and looked at Qin Tao. It was obvious that Mr. Qin planned to experiment with a new technology on this warship. What could it be?

Some of them had already guessed it, but they didn't say it out. They were waiting for Qin Tao's introduction.

"When we were working on the 052, we were very troubled by the problem of electromagnetic compatibility. We had to peel off the cocoon and find the problem, and spent a lot of time and energy. Now, we have entered the 21st century, and our brand new warship It is absolutely impossible to continue to use these independent electronic devices. The radars, electronic warfare and communication systems distributed throughout our warships can only complete their own functions. The degree of information fusion is not good, the weight and volume are large, and the radar reflection area is large. And there are electromagnetic compatibility problems at any time." Qin Tao looked at everyone: "To solve these problems, we have to use special shipboard integrated radio frequency technology."

"Is it the same as DDG1000?" Someone asked, sure enough, President Qin was going to say this.

Qin Tao shook his head: "No, it is more advanced than DDG1000. Although this warship claims to be integrated radio frequency technology, it actually only uses dual-band radar. We need to integrate all antennas and fully integrate them!"

The DDG1000 is particularly advanced. There is hardly any protruding radar on the bridge, but the radar is hidden inside, and it is not completely integrated. Its main detection system is a dual-band radar system: X-band SPY-3 Multifunction radar and S-band SPY-4 search radar.

The former is characterized by its excellent low-altitude search performance, especially its ability to detect hypersonic and sea-skimming anti-ship missiles. Sparrow", "Standard" -2/3 missiles, etc.

The latter is a conventional search radar, which plays the role of the original Aegis radar. Of course, these are active phased array systems, which are much better than the passive phased array of Aegis.

In the final analysis, it is just a dual-band radar, and it is all leftovers from us. Yes, the 346 radar used on our Aegis battleship is originally dual-band, except for the large-area S-band radar that is responsible for the search. In addition, there is a small area of ​​C-band responsible for irradiation.

"President Qin, what do you mean, we will hand over all the work that requires electronic equipment in a certain band to one antenna?" a leader said with difficulty.He can't believe this inference, isn't that too awesome?
"That's right, that's what it means." Qin Tao said: "The idea of ​​this integrated radio frequency system is to replace the current large number of antennas with several distributed multi-functional antennas. Simply put, it is an integrated public antenna. We need Using a modular, open and reconfigurable radio frequency sensor system architecture, a new algorithm is studied to complete function control and resource management, so that the antenna can simultaneously realize various radio frequency functions such as radar, electronic warfare and communication, navigation, and identification. Resource Sharing."

"Can you be more specific?"

Although the concept has been said very popularly, but the big guys still don't understand.

"The key is the bridge. Our integrated bridge requires antennas of four different bands, namely S, X, C, and L. We know that the electromagnetic radiation on warships is mainly these four, so With these four different radar antennas, we can complete the electromagnetic radiation needs of all electronic devices."

Qin Tao began to introduce to everyone.

"First of all, our main S-band active phased array radar is still deployed in the previous position. The four antennas cover the 360-degree airspace, which can grasp the situation of the entire airspace, detect, track, identify, and guide missiles to attack long-range targets. , is the core of our warship, and at the same time, due to the low installation position of this radar, we also need to integrate an X-band phased array radar at a high position on the main mast."

The previous shield ships were always criticized: the installation position was too low, and the early warning ability for targets flying at ultra-low altitude was insufficient!Europe is even swollen face to pretend to be fat, have you seen it?Our radar is high!We can better detect ultra-low-altitude targets, so what if you can detect [-] kilometers, or you can't defend against ultra-low-altitude targets!

Well, let’s change it now, let’s use two sets, we can take care of both high altitude and low altitude, see what you guys say, if you have the ability, you can also use two sets.

Europeans are definitely not capable, because they are poor.So, just watch Dongfang's 055!
"Currently, our Hongqi-[-] no longer needs target illumination, but our medium-range air defense missiles still need it. Therefore, this X-band radar can undertake low-altitude and ultra-low-altitude target search tasks, and provide our medium-range air defense missiles when needed." Missiles provide target illumination tasks, and at the same time, the X-band is still in the navigation radar band, and our radar system should also undertake the task of warship navigation."

Everyone nodded and expressed their support for Qin Tao's introduction.

"Next is the C-band. Although our Hongqi-[-] does not require target illumination, it may also require command transmission. This requires a C-band radar to achieve this. However, our C-band radar is not only for Hongqi-[-]. It also has more important role."

"What does it do?"

"Anti-missile."

Hearing Qin Tao's words, everyone was shocked.

In the past, ballistic missiles were once considered weapons that could not be intercepted, and they could only enhance their own ballistic missile strength to form a dynamic balance. But now, with the development of technology, a certain country has started the research and development of anti-missiles. After the absolute security of the aspect, it will be unscrupulous.

And our side has no choice but to take countermeasures.

On the one hand, it is orbit-changing technology, which improves the attack capability of ballistic missiles and disables the opponent's anti-missile weapons. The other is to have the same interception capability. In comparison, the latter is more difficult, but there is no choice.

China has started the research and development of anti-missile projects, starting with short-range missiles, and gradually has the ability to intercept intercontinental ballistic missiles.

Compared with land-based, sea-based has greater advantages, because land-based can only intercept ballistic missiles when they fall, while sea-based can intercept in the middle or even ascending stage, and the effect is better.

If the country also wants to have sea-based interception equipment, it will definitely need advanced warships. This kind of 055 of our own side needs to take this requirement into consideration when developing it!

"Can this C-band be anti-missile?" Someone was curious: "When we were choosing between C-band and S-band, we used the latter, because the latter has a longer search distance. Is it far away?"

The original C-band radar can only achieve a search distance of [-] kilometers, while the S-band can reach [-] to [-] kilometers. Now with the development of technology, it can be expanded to [-] kilometers, which proves the success of the original choice.

What now?
If it is anti-missile, then the distance has to be increased.

Qin Tao nodded: "Yes, we chose the S-band Sea Star radar because of the distance, but this is the search distance, not the tracking distance. You should know the difference between search and tracking, right?"

When searching, the electromagnetic wave radiated by the T/R component is scattered, which is equivalent to a light bulb, which illuminates the light source to the entire room, and tracking is equivalent to focusing. When this light bulb is installed on a searchlight, a beam of light flies into the sky, and the irradiation distance much farther.

"That is to say, we still use the S-band to search, and when we find the target, then use the C-band radar antenna to illuminate the target?"

"That's right!"

The main radar used on the 055 is still 346A, but it must be a modification, and the detection distance is longer. After the target is detected, the C-band radar is used to illuminate the target. The waves all come together and fully meet the needs.

"But why are we switching the radar?"

"Accuracy." Qin Tao said: "Our S-band radar can only track, but cannot accurately locate and guide missile attacks. Only the C-band radar, which takes into account both accuracy and distance requirements, is the best choice. Our radar will become An important part of our CNMD, responsible for guiding the final attack."

The crowd nodded.

"Although our anti-missile system has not been developed yet, our warships must be prepared for this, and this radar needs to be installed." Wu Shengli nodded: "You just said, there is a fourth radar? "

"That's right, you just said that you want to poke a meter wave radar antenna in the back. This arrangement is too backward. Our meter wave radar can also be inherited on the front and assume the role of searching for stealth aircraft. Just like before, Mi The wave radar finds the target, and then sends it to our S-band for precise positioning."

The advantage of meter wave radar is that it can detect stealth aircraft. The disadvantage is that the error is too large, so it needs to work together. Either form a network with other warships to form a meter wave radar array, or mobilize the S-band after roughly observing the target position Radar radiates a large amount of electromagnetic waves, and the reflected echo is larger, so that the specific location can be detected.

However, the meter wave radar can also be phased array?In everyone's impression, meter wave radar antennas are all shelves, some are similar to Yagi antennas, and some are similar to fly swatters, but I have never seen a phased array meter wave radar.

Everyone is still skeptical about this.

"President Qin, can this meter wave radar also have a phased array?"

"Of course, don't doubt the creativity of our military research and development." Qin Tao said.

"President Qin, this is a glorious and arduous task."

"That's right, such a glorious and arduous task must of course be entrusted to the 14th Institute." Qin Tao said: "Believe in them, they will definitely complete the integrated radio frequency technology. Our brand new 055 warship will also become the world's first Warships with advanced integrated radio frequency technology are far ahead of other warships, allowing foreigners to see our strength. Of course, our Mingzhou Group will also cooperate. We are responsible for designing the style of the integrated mast. They are responsible for Install radar equipment on it, and we first build a model on land."

"This is not easy! Will it delay our 055 research and development time?" Wu Shengli asked.

"It depends on the choice of the navy. It will be very fast to transplant the electronic equipment of the current 052, but if this is the case, can it still be called a cross-age warship? It is simply to enlarge, Or do we need to improve performance? When this technology is developed and matured, we can also apply this technology on the island of our 003 aircraft carrier in the future. It will be much simpler then."

Qin Tao was afraid that these people had no courage, so he simply threw out the 003 aircraft carrier. This is a nuclear-powered aircraft carrier, and the style of construction has to be changed. The design work must still be done by Mingzhou Group. The navy has no courage now, and there will be no advanced ones in the future. Carrier!

"Okay, for our 003, we also need to develop this advanced technology, but I don't know how much it will cost."

"Money is not a problem. As our technology becomes more and more mature, the cost of these radar arrays will become lower and lower." Qin Tao said, "I also heard that our technology has already been marketed, and there are special The unit develops and produces such components, and the price of all the radar arrays we manufacture is cheaper than the Sampson radar of the British."

The advantage of low cost is once again shown, what we are best at is to make things from the high-end Western countries into cabbage prices!
"Okay, let's hand over this technology to the 14th Institute for research and development. I hope they will not disappoint us. Now the general parameters of this warship have been determined." Wu Shengli said: "Next, your Mingzhou Group is Shouldn't it be time to give the blueprint?"

"Do not."

"Do not?"

"I haven't finished talking yet. There are still some equipment that need to be installed on this kind of warship. Since the integrated radio frequency system needs to be developed, we might as well wait for other projects. This kind of warship is timeless."

"You don't mean the electromagnetic gun, do you?" Wu Shengli frowned. When that thing will mature, the big guys don't know!
The electromagnetic gun sounds tall, has a long range, is powerful, and can even hit satellites, but it is difficult to develop this brand new weapon, even surpassing the electromagnetic catapult. If you wait for the electromagnetic gun to board the ship, you still don’t know How many years will it take, and the most ideal progress of the navy is to wait until 002 enters service, and then it will be able to have this kind of warship escort.

Qin Tao shook his head: "It's not an electromagnetic gun."

"what is that?"

"Red Flag Ten." Qin Tao said: "Currently, there is still a gap in our close-in defense weapons, which needs to be filled by Red Flag Ten."

Long-range red flag nine, medium-range red flag sixteen, how close is it?If you get closer, you have to rely on 730 guns!If the vertically launched Hongqi Sixteen cannot reach it, you can only wait for it to fly close and use 730 to intercept it!
The gap in firepower in the middle is exactly the attack range of Hongqi Seven, but Hongqi Seven is outdated and needs to be replaced with a brand new short-range missile, which is Hongqi Ten.

Vertical launch endows the missile with the ability to attack in all directions, but at the same time, vertical launch also delays the missile for a long time. To deal with close-range targets, it must first fly into the sky and then dive down. Some responses are not timely.

Therefore, short-range missiles still have to be launched at an angle.

The obliquely launched Hongqi-[-] used to be the navy's main air defense missile. This missile has many shortcomings, especially the lack of multi-target attack capabilities. In an increasingly complex maritime environment, Hongqi-[-] is already quite old.

The Red Flag Ten was put into research and development under such circumstances. It is a weapon system that rivals Hiram.

The West is more likely to face a saturation attack. They are also tirelessly researching. In addition to the Aegis system, there is also Phalanx. They still feel that it is not enough. At the end of the 80s, the United States and Germany cooperated and worked together to come up with it. The Mu air defense missile was formally equipped in 93. In more than 180 interception experiments, the success rate exceeded 90.00%.

Its range is only nine kilometers, so it doesn't need to be too far away, but its firepower density is high, and the launcher has 24 tubes, which further increases its anti-saturation strike capability.

Afterwards, the Americans made persistent efforts and came up with Block1, Block2, etc., especially the infrared focal plane guidance method, which is ignored after launch, and has stronger anti-strike capabilities. Such equipment does not need the help of the warship's own fire control system at all.

A similar system is also needed domestically!The research and development of the Red Flag 055 kicked off, but Qin Tao didn't know when it would be successful. He just knew that the 052 destroyer needed this kind of advanced short-range protective weapon to further improve its survivability on the battlefield. After all, it It is much more expensive than [-].

"The research and development of Hongqi 055 is progressing well, and it should be able to catch up with our [-]." A leader said.

Qin Tao nodded: "Then this warship will be equipped with Red Flag Ten when it was designed. It is most suitable to be placed above the helicopter hangar at the stern. It is responsible for guarding the rear hemisphere. It is in the front, behind the hanging hair, and under the bridge. It is safer to put a 1130 naval gun."

"1130?"

"Yes, the upgraded version of 730." Qin Tao continued to introduce: "Upgrade the near-anti-aircraft gun from 7 tubes to 11 tubes, so that the rate of fire should exceed [-] rounds per minute. To be number one in the world.”

At present, the world's mainstream close-in defense weapons include the American Phalanx with a rate of fire of 4500 rounds per minute, and the Dutch goalkeeper system with a rate of fire of 4200 rounds per minute. , the old Maozi's plan is relatively simple: the two doors are combined together, and the rate of fire is directly doubled.

"It doesn't seem easy. It is not difficult for us to upgrade the seven tubes to eleven tubes. However, our current rate of fire of seven tubes is about 4200 rounds per minute. If we increase it to 11 tubes, it will increase to [-] rounds per minute at most. Minutes, if it is faster, the bomb supply system will not be able to keep up."

The domestically produced 730 has three rates of fire, the highest of which can reach the same level in the West. At the same time, there are 2200 rounds per minute of medium rate of fire and 1200 rounds per minute of low rate of fire. Now increasing the number of barrels can indeed increase the rate of fire, but it is limited. Because there is a fundamental problem to be solved: feeding the bombs.

730 is an external energy source, so don’t worry about turning it fast enough, just adjust the speed of the external motor, but the ammunition supply can’t keep up with it, and it still can’t achieve a high rate of fire.

"We use two-way alternate feeding." Qin Tao said: "One-way feeding is [-] rounds per minute, and two-way feeding can reach [-] rounds."

"The technology of two-way alternate bomb feeding is very difficult and requires high machining accuracy. If the technology is not up to standard, it will easily get stuck. Mr. Qin, are you sure we can do it?" The big guy is still skeptical.

"Of course, we don't have to be afraid of high processing precision. We have advanced processing technology. As long as we dare to think, we can achieve it. Everyone, if you want to intercept low-altitude sea-skimming anti-ship missiles, the higher the rate of fire, the better. There is no end to it. Now It’s just 11 tubes, and we may be able to produce 22 tubes in the future.”

"How much does it cost to shoot a shuttle? The navy can't afford it." Wu Shengli said: "Let's book the 1130 gun first, and assign tasks to the relevant units. I hope they can complete the research and development as soon as possible, so as not to drag down our 055."

After arranging this matter, Wu Shengli looked at Qin Tao: "Taozi, poke the red flag 1130 at the back and [-] at the front. Is the firepower of this close-in anti-aircraft gun a little insufficient? Do you want to add two more?"

"That's right, anyway, it's a big project, and there's still funds for two more close-in weapons."

Qin Tao shook his head: "Close-in weapons are just the last line of defense. I hope they will never be used, because using them will mean that our other interception methods will fail. If there are four such weapons, it means that we are too dissatisfied with our anti-aircraft missiles." trust."

A destroyer of [-] tons can put more anti-aircraft missiles, dig more launch holes, and improve the living conditions of the crew, etc. However, there is no need to deploy too many close-in anti-aircraft guns, which are not needed at all. Time, no more.

"Is it almost the same now?" Wu Shengli asked.

"Well." Qin Tao nodded: "Our warships are designed based on these parameters. We will produce the design drawings in about a month and hand them over to the navy for evaluation. By the way, the navy has to notify the relevant units to bid together. Fair enough."

"Bidding? That's right, it is indeed time to invite bidding, but I don't know if anyone will come to bid."
