Chapter 15 The first in the world

Stealth technology? This concept has been hyped up this year

It can already be predicted that with the development and progress of science and technology, especially military science and technology, stealth technology developed from camouflage technology has occupied an increasingly important position in military equipment. Over the years, all kinds of stealth military equipment have emerged in the world, from helicopters, fighters and bombers flying in the sky, to submarines, frigates, destroyers, and then to armored vehicles, tanks and even self-propelled artillery, all of which have adopted stealth technology to design, in order to ensure that their side can have the maximum survival rate.

In this vigorous stealth tide that has emerged from the United States, the domestic military has naturally realized that this is the trend of the development of military science and technology in the world, and stealth technology will inevitably become one of the most important components of military equipment in the future. Although limited to technological and scientific and technological factors, the development of stealth technology in China is still short, and it still lags behind the Americans in terms of achievements in stealth technology, but it has also developed its own stealth technology, especially in destroyers, frigates, high-speed missile boats, and so on, and has developed a considerable degree of stealth technology.

In modern warfare, there are fewer and fewer weapons and equipment that need to be visually launched, and more and more weapons use radar-guided firing methods; if they can successfully achieve stealth under the radar's nose, then they will occupy a huge advantage in amphibious landing operations

However, in stealth technology, a recognized worldwide problem is that as a combat equipment in amphibious landing operations, from the sea to the rear 2,000 meters: amphibious landing combat equipment mainly high-speed hovercraft, but from the sea to the land at a distance of 2,000 meters, it cannot achieve effective radar stealth.

This problem, even for the Americans who can achieve bomber stealth, is also a headache, in the US Navy's combat sequence, although the United States has always wanted to develop a type of stealth high-speed hovercraft to ensure the safety of the soldiers of the amphibious landing combat force, but unfortunately, it has been a lot of strength, and finally the US Navy has equipped its own marines, has always been the Marine Corps hated the LCAC high-speed hovercraft.

Could it be that Alice Group can bring us a bigger surprise this time? The generals glanced at each other in disbelief, with some disbelief in their eyes.

"Miss Jill, can you explain it to us?" When you look at me, generals, and I look at you, Minister Liang, who took the lead, didn't have so many scruples, and asked Gil directly.

"Of course, that's exactly what I'm going to say to you next," the reaction of these high-ranking generals made Jill very satisfied, and the little girl cleared her mouth and didn't sell much, along with Jill's words, the shape of the three-dimensional projection of the high-speed hovercraft next to her suddenly began to enlarge at this moment.

With the enlargement of the shape, it can be clearly seen that the shape of this hovercraft is very different from that of ordinary large hovercraft, there are almost not too many arc lines, all the lines are straight edges and right angles, and there are almost no vertical faces, all the faces are showing a little arc. The superstructure of the hovercraft, which is most easily detected by radar waves, is designed to tilt backwards at an angle to reflect the radar waves that hit the hovercraft hull into the sky as much as possible.

The generals present are all experts, and when they see this hull design, they naturally understand very clearly that this is a high-speed hovercraft with a stealth design in terms of appearance.

If you look closely, there are no antennas on the hovercraft similar to the one on which the Ukrainian "European Bison" told the hovercraft, all the antennas are integrated, and there are no round, spherical or long rotating antennas, all the antennas are covered by a stealth design shell.

What's even better is that with the step-by-step automatic explanation of the three-dimensional design model, the generals can clearly see that after the high-speed hovercraft is filled with all kinds of materials and landing weapons and equipment, two huge composite top covers are raised from both sides of the hovercraft, and the materials and weapons and equipment loaded on the entire hovercraft are tightly covered below, avoiding that the hovercraft can be invisible, but the equipment carried on the hovercraft cannot be invisible, and when the radar wave hits the hovercraft, the various materials carried on the hovercraft" betrayed the embarrassing situation of the specific location of the hovercraft. ,

The shape and superstructure of the entire hovercraft are clean and tidy. Judging by the shape design alone, the generals have already given the shape design of this hovercraft a score of 90 points in their hearts...... From the point of view of stealth, neither the Ukrainian "European Bison" hovercraft nor the American LCAC hovercraft can compare to this AI-600.

Don't think that the hull is a very simple thing to use stealth design, in fact, the use of stealth shape design of ships, in many places are completely different from the previous warships, in the hull of the ship, many places have changed even more, in the world, the ability to design the hull stealth shape of the country, but there are only so few.

"I believe that your respected generals have seen that this high-speed hovercraft has far surpassed the same type of products in the world in terms of shape design, in addition to what your respected generals have seen, after the official production, we will also paint stealth paint and stealth paint on the hull shell. Of course, whether to paint stealth coating, depends on your opinion, at the time of the original design commission, you did not entrust us to design a stealth high-speed hovercraft, so the cost of stealth paint can not be calculated in the overall price of the hull. ”

The so-called stealth coating, some similar to the stealth paint painted on the stealth aircraft, has a good absorption and reflection effect on radar waves, if the shape of the aircraft also adopts the stealth design, then it will play a huge role in the overall stealth effect of the aircraft.

Of course, in terms of price, the price of the stealth livery is naturally much higher.

The so-called stealth paint is the hull paint of the ocean gray painted on the ship's hull, which is usually ocean gray or the kind of marine camouflage painted on the ship.

In addition to the function of anti-rust, the ocean only has a simple long-distance visual stealth effect -- this stealth principle is the same as the camouflage uniform worn by ordinary soldiers, which is similar to the background color through its own color, and achieves the stealth effect by confusing the line of sight of military observers, and basically does not have the ability to reflect radar waves and absorb radar waves.

Of course, if it is this kind of stealth paint, the price is undoubtedly much cheaper.

Minister Liang glanced at several generals, of course they know which effect is better, there is no doubt that if stealth paint can be used, the effect of stealth will rise a lot, but at the same time, there is a very serious problem: the price of stealth paint is usually extremely expensive, to some extent, high-speed hovercraft is a war consumable, is it necessary to use stealth paint for this thing?

However, the huge role that stealth paint can play in wartime deeply tempts the generals present, making them itch, uncomfortable, and unstoppable.

"So...... Miss Jill," Minister Liang pondered for a while, but decided to ask about the specific cost, if the cost can be controlled within a certain range, it is not non-negotiable, "If stealth paint is used, what is the stealth effect of the ship?" How much will the overall cost go up? ”

Yes, how much will the cost go up? The generals' spirits were suddenly shocked: yes, the cost of stealth paint is certainly very high, but the things produced by Alice Group have always been known for their high quality and low price, if the cost of this stealth paint is not high, and the stealth effect is not bad, it is not an unacceptable thing to equip this big guy with stealth paint.

"$5 million," Xiao Chenxi neatly raised five white and tender fingers, "The overall cost will rise by $5 million, and the cost of stealth painting will account for one-sixth of the overall cost, and the purchase price of a single hovercraft will rise to $35 million." ”

$5 million? Several generals glanced at each other and breathed a sigh of relief in their hearts, if it was $5 million, the price would not rise much...... The price of the Americans' F-22 stealth fighter is $150 million, of which the cost of stealth paint alone accounts for more than 1,000 perfect yuan. What is the surface area of the hull of this AI-600 high-speed hovercraft?

Minister Liang also bowed slightly in his heart, the country has been rich in recent years, if the cost of increasing by 5 million US dollars can bring greater certainty to the landing operation, it is not unacceptable, but I don't know what the specific stealth effect is?

When Minister Liang was pondering this problem, Jill also said about this problem, "As for the specific stealth effect, the result of our actual test is that compared with the stealth paint used on the US F-22 heavy stealth fighter, the overall performance is only about five percentage points lower, that is, it is equivalent to 95 of the stealth coating performance of the US F-22 heavy stealth fighter." ”,

Huh, if this is really the case, then it must be on this stealth paint Minister Liang and the generals suddenly brightened their eyes

The price is only a few tenths of the stealth paint used by the American F-22 heavy stealth fighter, but the overall stealth effect can reach 95% of the stealth effect of the stealth paint. Fools don't do it

Of course, none of these guys are stupid, and they naturally understand that all this will have to wait for the actual test results before they can make a final decision, and the strict military procurement system, testing system, and accountability system make these guys not dare to make decisions according to their personal preferences like local government officials.

"So...... Miss Jill, we accept this part of the high cost, but I need to add that these high-speed hovercraft that we ordered are not stealth painted when they are delivered, you just need to deliver these stealth paints to us and teach our experts how to maintain and paint, is there a problem? Lao Liang pondered for a moment and said to Jill.

"Absolutely." Jill nodded slightly, nodding in response.

She understands very well what Minister Liang means, and what Minister Liang means is that the military is very enthusiastic about painting this type of AI-600 high-speed hovercraft with stealth paint, but the use of stealth paint is not very long, just like the American F7A stealth fighter, F-22 heavy stealth fighter, and the B-2 stealth strategic bomber that has been tossed away by Zhang Lan, the stealth paint is very expensive and delicate, and every time it goes out to perform a mission, the stealth paint must be repainted after the plane returns. Otherwise, the stealth effect will be greatly reduced.

The military's calculation is probably like this: I bought stealth paint, and on weekdays, I relied on stealth paint and stealth appearance to carry out patrol, anti-smuggling and pirate tasks, and did not paint stealth paint to save costs; When the war is about to start, this is the time to paint these high-speed hovercraft with stealth paint to increase the certainty of victory against the enemy in battle.

In addition to the cost of use, Jill pondered that perhaps they were worried that some information from their side would tell the Americans, and they were still guarding themselves in their hearts. This little calculation is not shrewd.

But Jill is not annoyed, the Alice Group actually wishes that the military would do this, so for the Alice Group, it saves a lot of effort, since the military is willing to do this, then of course he is happy to do so.

Seeing that Jill seemed to care about doing this, Minister Liang breathed a sigh of relief in his heart.

In fact, Minister Liang thought about it almost the same as Jill guessed, he planned to do so, wanting to save some money on the country's originally not generous military spending, and he was still a little worried about whether Jill would disagree, but the result was a big relief for him.

As Minister Liang's subordinates, the officers who came with them understood why their boss said this as soon as Lao Liang's words came out, and after hearing Jill's reply, they admired the generosity of the Alice Group, and at the same time were heartbroken for their boss's dedication to the country.

"Of course, in addition to the stealth design in the appearance, we also use some other stealth design, compared with the traditional gas turbine-driven hovercraft, because we use the fuel cell + motor power arrangement scheme, the moving parts of the whole power system are reduced by more than 90, so the overall noise and vibration of the hull has decreased a lot, our AI-600 high-speed hovercraft noise characteristics are smaller, the vibration is smaller, and the volume and weight of the power system are lighter, and the infrared signal characteristics are also smaller, which is more conducive to hovercraft to avoid danger at sea. ”

Several generals nodded their heads again and again, especially the two rear admirals of the navy, who looked even more concerned.

These two rear admirals have been on a high-speed hovercraft in the past, and they understand the pain of staying on the hovercraft, not to mention the violent vibration of the high-speed hovercraft when it is speeding at high speed at sea, and the huge noise emitted by the power system alone is a little unbearable...... Almost all high-speed hovercraft are using gas turbines developed from jet engines, in the past, flying in the sky, there are ** kilometers away from you The noise of the aircraft, you can hear clearly, can you imagine what it is like to be only twenty or thirty meters away from an engine that can make such a loud noise? ,

What's even more tragic is that these high-speed hovercraft are usually equipped with at least three high-power gas turbines, and the Ukrainian "European Bison" high-speed hovercraft is equipped with five large gas turbines for the first time in history......

Under such noise, even if you wear thick sound-isolating earplugs, it can make your noisy heart upset, blood pressure rise, and the combat effectiveness of the soldier greatly reduced, not to mention the impact of the violent bumps on the combat effectiveness of the soldier in the process of high-speed travel...... How to effectively maintain the combat effectiveness of soldiers on high-speed hovercraft has always been a major problem that all parties have been thinking about and urgently need to solve.

Therefore, Alice Group's major innovation in high-speed hovercraft power is more of a major change in the combat effectiveness of the army.

The generals of the General Armament Department, including the boss of the General Armament Department, Minister Liang, are very satisfied with the stealth high-speed hovercraft designed by the Alice Group, and the rest of the things will be handed over to the ship experts who come with them, and some specific performance and technical details will be handed over to these experts to evaluate.

But all the generals believe that the stealth high-speed hovercraft designed by the Alice Group is far from the day when it is officially equipped to the military, in fact, it is just around the corner, over the years, the various military products designed by the Alice Group have never disappointed the military, and some military representatives have even complained in private about those state-owned military units, "Look at these things of yours, what are they, the quality of the products is much worse than that of the Alice Group, but the price is very expensive."

"By the way, we've got a new piece of equipment here, huh, would you like to take a look?" Suddenly remembered a thing he asked Xiao Chenxi to make a while ago, at the dinner, Zhang Lan pondered for a while and asked Minister Liang.

"Huh? Got something new? What is it? Hearing Zhang Lan say that there were new things, Minister Liang couldn't help but feel a little excited, what new things can Alice Group come up with this time?

"It's not a good thing," Zhang Lan smiled a little shyly, "It's just a sniper rifle." ”
