A big country of aerospace with black technology

"Professor Zhang, there is recent news that our country plans to develop a laser air defense system."

The female host smiled and asked her opening question:

"I wonder if this is true?"

Zhang Zhaozhong, who was later hailed as the director of the Strategic Deception Bureau, was still a middle-aged man at this time with beautiful black hair.

"As far as I know, the development of the laser air defense system is mainly done in cooperation with others. It is still a conceptual weapon experimental project."

Zhang Zhaozhong said with his magnetic voice that is comparable to a bass.

"We still don't have much investment in laser weapons. After all, Yingjiang has been working on it for so many years and still hasn't figured it out. It's not that easy for us to figure it out."

As a professional in the military, Zhang Zhaozhong's reputation at this time was not as special as it would be in later generations.

Therefore, many people present chose to believe his words.

His professional background gave his speech a strong endorsement.

“The one that is closest to practicality in the world right now is Yingjiang’s IFPC high-energy laser.”

"In previous actual battles, this was used to burn down many tank sighting equipment of the belligerents."

"But in recent years, everyone has been working hard to improve the energy level of lasers and want to apply it to direct attacks."

At this time, the female host took advantage of the opportunity and asked: "What does it look like when laser is used for direct attack?"

"Will it be like the laser guns or laser swords we saw in the movies?"

"No, a movie is a movie after all." Zhang Zhaozhong shook his head after listening to the host's question.

"The laser attenuation and diffusion are very weak without any interference."

"Scientists once conducted an experiment and irradiated a high-power laser beam on the moon. After attenuation of 380,000 kilometers, the scattering surface on the lunar surface was only a few meters in size."

"You can imagine that if it is used in the attack field, the laser will not stop unless it is directly blocked by an object."

"So, the laser gun or the laser sword in the movie is very unreasonable."

"The biggest advantage of laser is its fast speed and slow attenuation. After all, the speed of light is still the fastest speed we have discovered."

Zhang Zhaozhong briefly introduced the advantages of laser application in weapons, and then began to focus on the application of laser in the field of direct attack:

"The current concept of laser weapons is to be used more as a non-lethal weapon. The application scenarios are anti-terrorism and riot prevention."

"Because in this scenario, it may not be appropriate to use more lethal weapons."

"For example, when facing terrorists who are holding hostages, you can't say, I just throw a 105 shell in. That's not appropriate."

"In this case, using small and medium-power laser weapons to irradiate terrorists can cause deafening flash explosions and nerve pain to the terrorists in a short period of time, thereby rendering them incapacitated. This can To a great extent, unnecessary casualties that may occur during the hostage rescue process will be reduced."

With the development of the world, there are more and more similar terrorist attacks, kidnappings and extortions around the world. If hostages can be rescued in these scenarios, this is also the direction of exploration for various countries.

What Zhang Zhaozhong just said is also a direction that everyone is exploring.

There is relatively little contact in this area in China, mainly because the society as a whole has been in a harmonious state in recent years, and there has been no similar situation.

Research beyond these will naturally be slower.

What Zhang Zhaozhong said mainly comes from Yingjiang's own research.

After all, they often encounter various attacks at home and abroad.

"Most of the small and medium-sized lasers you mentioned are used as non-lethal weapons. What about large lasers? Will they be used as lethal weapons?"

After Zhang Zhaozhong finished speaking, the female host promptly asked the next question. This was also her professionalism as a host.

“Currently, both in the East and the West, there are relatively few physical objects being researched and produced for large-scale lasers, and they are mainly concentrated in the field of theoretical research.”

Zhang Zhaozhong also did a lot of homework before going on the show. After adding the information he had learned from many experts before, he was able to talk directly:

"We believe that large lasers, so-called megawatt lasers, are actually still used in the defense field."

"For example, areas such as air defense and anti-missile are where large lasers come into play."

"The joint laser air defense project we are participating in this time is the application field of large-scale lasers in the megawatt range."

"As for direct casualties, the power of lasers is actually not as powerful as everyone imagines. Even a large laser can hardly make a hole in a person."

Human bones are very strong and can withstand strong enough heat accumulation.

This makes the way for lasers to cause direct damage, which is to cause damage to the surfaces of various objects through a large amount of heat accumulation in a short period of time, very slowly.

To put it simply, if you want to kill someone with a laser, it is cheaper and more convenient to just give him a bullet.

Therefore, Zhang Zhaozhong was still more cautious when talking about these things, emphasizing its non-lethal nature and its main application in the field of defense.

"Professor Zhang, since lasers are so powerful, do we have any means to defend them?"

After a big round of applause in the studio, the host asked the next question.

"After all, it seems that we are still lagging far behind other countries in the laser field."

"We have just talked about that laser is more of a defensive weapon, and offensively it is mainly used to destroy some more sophisticated optical equipment." Zhang Zhaozhong said.

"For example, some low-power lasers mounted on infantry fighting vehicles can damage the enemy's tank optical equipment."

"However, there is actually no need for us to worry about this. Lasers have relatively high requirements for the environment in which they are used."

"Generally speaking, it is only suitable for some areas with relatively good air environment, such as some plains, deserts, maritime areas, etc."

"You think, once there is heavy fog or haze weather, laser weapons will be of little use."

"Because, whether it is dense water droplets in heavy fog or particulate matter in haze weather, the laser will be greatly attenuated."

"Based on our country's current conditions, the places where laser weapons are more suitable are actually extremely limited."

When Zhang Zhaozhong explained this, he did not think that his words would become a joke later.

"Then in your opinion, do we have no need to develop laser weapons?"

The host's question was a bit confusing, but it was still among the list of questions that had been answered before, so Zhang Zhaozhong didn't feel much at all.

"That's not it, that's not it." Zhang Zhaozhong shook his head as usual and said:

"I just said that laser weapons are suitable for use on the sea. In the future, we will definitely have to compete with others on the ocean."

"Modern maritime confrontations are not like formations of bombardments in the era of giant ships and cannons a hundred years ago. They are basically confrontations between missiles and aircraft carriers."

"This puts forward higher requirements for our air defense and anti-missile capabilities. Laser weapons have advantages that others do not have in this regard."

"And large ship platforms are more suitable for carrying large lasers. Unlike land-based lasers, when the power of lasers increases, the power supply cannot keep up."

A big reason for land-based lasers now is the problem of power supply. Even if a gas turbine is used as the power source, which can directly generate power for power equipment, power is always a big problem.

The power output of large ships is much larger, which can meet the energy needs of large lasers.

"Because the laser generator on the ship is mainly used to target the air, the attenuation of the laser energy is relatively weak, and it can effectively attack incoming missiles and drones."

"Unless you encounter some severe weather such as typhoons and storms, it may cause serious interference to laser weapons. However, in such a case, it will cause considerable interference to the weapon itself."

Such a military interview program ended with Professor Zhang Zhaozhong’s optimism about laser weapons.

After the show was broadcast, many people had new ideas about the future of laser weapons.

For example, a month later, Yingjiang took advantage of the situation and released the news that it would install laser weapons on its next-generation destroyer.

Suddenly, many countries with some industrial strength saw the direction of the next generation of air defense.

As a result, many began to invest heavily in laser weapons, hoping to take the lead.

"Xingyang, what do you think of the laser craze that's rising in the world now?" The old leader, who had a good relationship with Zhang Xingyang, also came to him one day in April and asked.

"Laser does have indelible development potential in the field of next-generation air defense weapons."

Zhang Xingyang's words were very cautious.

"Let me just ask directly, is the laser interception system built by you and those rich people really useful to us?"

It was not the first day that the old chief had met Zhang Xingyang, so he did not make some subtle and euphemistic remarks and asked directly.

"To be honest, it is of some use, but I don't think it is very useful at this stage."

Upon seeing this, Zhang Xingyang expressed his opinion openly.

"The situation they have to face is different from us. Their enemies don't even have serious industrial capabilities. They basically have homemade weapons. In this case, lasers can easily shoot down these homemade rockets and artillery shells. .”

"But for countries with industrial strength, especially in the chemical industry, it is difficult to win over regular military products."

The old chief was a little confused at this time and asked quickly: "Is there any other explanation for this?"

"This question involves the nature of lasers."

Zhang Xingyang glanced at the old leader a few times, and said in his doubtful eyes:

"The essence of laser is the directional propagation of photons. The directional photons are released when particles reduce their energy level."

"When a laser irradiates aircraft, missiles, artillery shells, etc., the photons will quickly increase the temperature of the irradiated area, quickly reach its melting point, and damage the aircraft, missiles, artillery shells, etc."

"So the key to the problem is that once the melting point of the flying object is very high, the laser will need to be irradiated for a long time to be effective, and the interception efficiency in actual combat will be relatively low."

The old chief also slowly understood at this time: "In other words, if we use titanium alloy or tungsten alloy to make weapons, they will not be able to use laser interception?"

"But the money spent in this way is a bit too much."

Zhang Xingyang shook his head and said, "It's not that troublesome."

"Remember what I just said, it is easier for countries with more developed chemical industries to crack laser interception?"

Zhang Xingyang did not directly explain this issue, but turned around and talked about another matter.

"We have recently developed a boron phenolic resin material that only requires a 2.5 mm coating to maintain the surface temperature of the material below 230 degrees Celsius under laser irradiation with a power of 500 watts per square centimeter. ."

The old chief frowned after hearing this. He had vaguely guessed the relationship between the two, but he was not completely sure yet.

"Just say it!" the old chief said.

"Our missiles generally use aluminum bodies with a melting point of 400 degrees Celsius. This means that after using this coating, the missile can ignore the irradiation of laser weapons."

"Five hundred watts per square centimeter is equivalent to how many watts of laser transmitter?" The old chief quickly discovered a point that Zhang Xingyang had not explained clearly.

"Theoretically, a 6-megawatt laser generator is needed to generate 500 watts per square centimeter at a distance of tens of kilometers."

Zhang Xingyang quickly revealed a series of numbers:

"The most advanced laser generator in the world currently only has 120 kilowatts. It is estimated that it can only produce 12 watts per square centimeter at a distance of ten kilometers."

This laser transmitter is only a product of experiments, and there is still a long way to go in actual combat.

"So the speed of development of laser defense methods is much higher than the speed of development of offensive methods, right?" After listening to this, the old chief said thoughtfully:

"Does anyone else know about this besides the people in your institute?"

The old chief obviously thought that he could do something with this matter.

"No, everyone has signed a confidentiality agreement and will not disclose it." Zhang Xingyang said.

"That's good, it's time to let them suffer a little." The old chief said with a smile.

It seems that we have seen that those people finally developed a megawatt laser, and then found that the weapon they spent tens of billions of dollars to develop suddenly had no use!

It's time for the war and neglect bureaus to get to work again!
