"Xingyang, you did a good job!"
After hearing that the missile's error was only three meters, the old leader was half shocked and half pleased and patted Zhang Xingyang on the shoulder.
Even Zhang Xingyang, who had known in advance that the missile's accuracy could reach ten meters, was a little surprised by this result.
After all, being able to reach the ten-meter level means that the missile's error will be about ten meters.
But the error was only three meters, which was still beyond everyone's expectations.
"This time it must be an accident. Normally the error should be around ten meters."
Although the results were good, Zhang Xingyang did not let such good news go to his head, and still maintained a cool head as a scientific researcher.
"Even if there is a cost of luck, it still cannot take away the fact that your technical achievements are very successful."
Faced with Zhang Xingyang's humble words, the old chief did not hesitate to praise him.
"All of you are heroes!"
"especially you."
Even though he did not have in-depth contact with the missile research and development process, he got information based on the old chief.
The entire process of hypersonic missiles, from project establishment to research and development, is almost all driven by Zhang Xingyang alone.
Many of the problems encountered here were also solved by Zhang Xingyang.
Not only in terms of technology, but also in terms of engineering experiments, many of which were solved by Zhang Xingyang.
For example, the most important ramjet combined cycle engine, which can smoothly transition between sub-combustion, super-combustion and other multi-modes, was solved by Zhang Xingyang.
But Zhang Xingyang himself doesn't have that much emotion.
Zhang Xingyang raised his head and looked at the clear blue sky, and said thoughtfully:
"I just did what any scientific researcher should do."
Facing the humble Zhang Xingyang, the old chief had become somewhat accustomed to him during these years of contact with him.
But he still sighed.
"You are still too modest."
"With the hypersonic ballistic missiles developed under the leadership of your Rocket Research Institute, we will be able to speak louder in the face of enemy threats in the future."
In this world, when countries interact with each other, the first thing they value is national strength, and in direct confrontation, the most important thing is their own military strength.
Why in the past ten or twenty years, China has almost always played the image of harmlessness to humans and animals internationally.
The most important thing is that his own strength is not strong enough.
Only with the backing of sufficient force can we speak loudly in international exchanges.
Facing the already somewhat proud old chief, Zhang Xingyang thought for a while and then said:
"not enough."
"That alone is not enough."
The old leader was a little surprised. After all, in his opinion, hypersonic missiles with a range of more than 7,000 kilometers, almost reaching the category of intercontinental ballistic missiles, and speeds exceeding Mach 7 are almost unrivaled in the world.
"Why?"
"We also need anti-ship, submarine-launched and other models."
Zhang Xingyang said to the old man in front of him with some seriousness.
The Dongfeng-17 hypersonic ballistic missile tested this time is a ground attack model, mainly used to attack important enemy ground targets.
However, as we all know, the main military threat faced by the country still comes from the sea.
In particular, the enemy's numerous aircraft carrier battle groups have always been a major worry for everyone.
This is why Zhang Xingyang attaches so much importance to the anti-ship model. After all, this is a magic weapon that can deliver a fatal blow to the enemy's aircraft carrier battle group.
"Anti-ship?"
The old chief was a little surprised. After all, anti-ship models of ballistic missiles are not very common these days.
Generally speaking, ballistic missiles are still used to directly attack important ground targets of the opponent.
In particular, long-range ballistic missiles equipped with nuclear warheads are all used to attack land targets.
"To be precise, it's an anti-aircraft carrier."
Zhang Xingyang talked about the specific role of anti-ship missiles.
"The aircraft carrier is the core of the naval battle group. Once the attack is completed, the opponent's battle group will lose more than half of its combat effectiveness."
The old chief didn't know this, but he was a little confused:
"Isn't it easy for anti-ship missiles to break through the air defense and anti-missile systems on the opposite side?"
After all, the Eagle Navy Aegis system at this time is claimed to be the most advanced air defense and anti-missile system in the world.
Although in its previous battles, except for the mistake of shooting down a commercial airliner in 1988, resulting in the death of 260 people, there were no actual actual results.
But it still does not prevent everyone from trying to use their imagination to imagine its combat effectiveness to the extreme.
"It's not as difficult as you think."
Zhang Xingyang first gave a conclusion that ordinary people may not accept, and then explained:
"Today's Aegis system mainly relies on the standard series of air defense missiles to intercept flying objects such as aircraft and missiles."
"However, the speed of standard series missiles is generally slow, and most can only reach a speed of Mach 2."
"Compared with our hypersonic missiles, they are like a turtle crawling, and it is difficult to complete the interception work."
"Moreover, standard anti-aircraft missiles still use explosion interception, and the interception effect on hypersonic missiles is very poor."
The best way to deal with hypersonic missiles is to use kinetic energy destruction to ensure that the warhead of the missile can be completely destroyed.
Otherwise, there may be a situation where although the missile's engine is destroyed, it can still continue to hit the target under the action of inertia.
And because the warhead has not been completely destroyed, a serious explosion will still occur.
Yingjiang's army once encountered such a situation in a war. Although the anti-aircraft missile destroyed the engine of the ballistic missile on the opposite side, it did not completely destroy the warhead and still caused heavy casualties to itself.
"As for the close-in defense artillery system, it may not be bad to defeat a dozen slow drones, but it is basically impossible to intercept hypersonic missiles."
"So it is very simple for our hypersonic missiles to break through the opponent's anti-missile system."
"In a word, it's nothing to be afraid of."
When Zhang Xingyang said this, he exuded an arrogance that was unimaginable to ordinary people.
It seemed that Takao-chan, who was extremely powerful in the eyes of others, was just a withered bone in a grave in his eyes.
We can't blame Zhang Xingyang for having such an attitude. After all, in the era he lived in, Yingjiang had already split due to its own problems.
It has become a relatively backward country.
So in his eyes, Yingjiang had indeed died suddenly.
"The most difficult thing is the guidance problem."
"The electromagnetic environment above the sea is more complex than above the ground because of the impact of waves."
"And the aircraft carrier battle group is different from a fixed ground target. It will move during the entire strike process."
"This puts forward higher requirements for the terminal guidance of the missile."
Although the maximum speed of a hypersonic missile can reach fifteen times the speed of sound, in order to accurately hit the target at the end, it still needs to reduce its speed, which is only around Mach 8 at most.
As for hypersonic ballistic missiles, it takes more than twenty minutes from launch to hitting the target.
This time is enough time for the aircraft carrier battle group to travel 20 kilometers.
The terminal speed of the missile is very fast, which also brings about another problem, that is, the time left for the missile guidance system is also very short.
This places higher requirements on the guidance system of anti-ship missiles than on ground attack models.
"But this problem will not be a problem after our new generation of guidance satellites are launched."
Zhang Xingyang smiled after finishing speaking.
"Especially after being combined with our communication satellites, the positioning accuracy can reach meter level, and the coverage area is much larger than it is now, which can only cover the entire country."
After listening to Zhang Xingyang's talk about the advantages and disadvantages of anti-ship hypersonic missiles, the old leader was thoughtful:
"Do you think there will be a similar hypersonic missile project in Yingjiang?"
At this time, although Yingjiang has begun internal research and development of hypersonic weapons, it is still in the technical demonstration stage.
They have not yet unanimously agreed on the performance parameters that the weapon needs to achieve.
So now the outside world doesn't know much about Yingjiang's hypersonic weapons project.
This is why the old chief only speculated that Eagle Sauce may be the reason why such a project exists.
"There may be, but they still have great difficulties in developing similar weapons."
After all, in Zhang Xingyang's memory, Yingjiang was not able to complete the development of hypersonic weapons even after more than 20 years.
Now even though they have developed hypersonic weapons research and development projects due to the butterfly effect caused by their own appearance.
There will not be any particularly big threat, because they have technical shortcomings in many aspects of hypersonic missiles.
"The bottom line is, they don't have a hypersonic wind tunnel."
In order to develop hypersonic weapons in China, the investment in hypersonic wind tunnels alone has reached more than 10 billion.
This does not include other facilities supporting the wind tunnel, as well as coal from thermal power plants, etc.
If all investments are added up, the country has spent at least 20 billion on the Dongfeng-17 waverider hypersonic ballistic missile!
You know, this is 20 billion in the 2000s!
The annual fiscal revenue at this time is only more than 700 billion, and 0.3% of it is spent just for this weapon, which is a terrifying figure.
If it weren't for the big head here, the funds for the construction of hypersonic wind tunnels would have been snatched from the Western Quantum Fund during the financial crisis.
The Rocket Research Institute wants to complete the research and development of such an important national weapon by relying solely on its own strength.
Don't know how long it will take yet.
Although the Rocket Research Institute's current annual revenue can reach billions, it also has thousands of employees to support, and it is impossible to invest all the funds in several years in this area.
"Even if they want to spend money to build a hypersonic wind tunnel, it's not that easy."
"The shock wave wind tunnel is still very difficult."
If you want to generate a speed that can test missiles about fifteen times the speed of sound, the shock wave wind tunnel is almost the only option in this era.
Other methods are either too difficult or cost too much.
"Even if we take a step back, they have completed the research and development of hypersonic missiles."
"That will be at least several years later."
"This period of time is enough for us to build our own missile defense system."
Zhang Xingyang said indifferently.
National Missile Defense System, the English name is National Missile Defense, or NMD for short.
"How do you think our national missile defense system should be built?"
The old chief asked with a little curiosity. He wanted to hear the opinion of Zhang Xingyang, a professional.
"First of all, we need to clarify the defense targets of the missile defense system."
"Our national missile defense system mainly defends against hostile ballistic missiles."
"The second thing is, at what stage of the missile will we conduct anti-missile missiles."
"Is it the initial stage just after the missile is launched, the middle stage of flight outside the atmosphere, or the end after re-entering the atmosphere."
"From a technical point of view, the mid-course anti-missile effect is the best."
"If we are going to build a missile defense system, the most important thing is to build a midcourse anti-missile system."
"Because during this period of flight, the trajectory of the missile is very stable and is relatively easy to predict by supercomputer."
"The last thing is missile defense."
"As I said just now, the way the missile explodes and destroys it, the defense effect is average."
"So if you want to achieve complete destruction, it's best to use kinetic energy destruction."
"Using high-strength alloy, it relies on its own kinetic energy to impact, completely destroying incoming missiles."
Then Zhang Xingyang described to the old chief the working picture of the national missile defense system to be established in the future.
After the enemy's ballistic missiles took off, the reconnaissance equipment on the space satellite first detected their missiles taking off.
The information is then transmitted to the 24-hour information command center, which determines the enemy's attack.
Issue an order to turn on the anti-missile missile and prepare for launch.
At the same time, the command center transmits the data detected by the reconnaissance equipment to the supercomputer to calculate the trajectory of the incoming missile.
Because ordinary ballistic missiles do not adopt the unique domestic Qian Xuesen trajectory, 70% of the flight section is outside the atmosphere, and during this period, the flight trajectory is stable, and supercomputers can easily calculate the missile's flight trajectory.
After analyzing the trajectory of the missile, the data is transmitted to the onboard computer of the anti-missile missile.
After receiving the data, the anti-missile missile is fired and launched into the air.
Because the range of anti-missile missiles often overflows, the missile is in the early stages of takeoff.
It is necessary to perform a large-angle spiral in the sky to consume excess fuel.
In the sky, a very strange image is drawn, which makes people very confused.
After the spiral is complete and excess fuel is consumed.
The anti-missile missile begins to accelerate and will gain altitude.
All the way up to the same extra-atmospheric altitude as the incoming ballistic missile.
And under the guidance of the missile's onboard computer, it directly collided with the incoming ballistic missile!
To achieve the purpose of destroying incoming ballistic missiles. (End of chapter)
