Different from the gloom and gloom in the deep space civilization base cluster, after receiving the report on the attack, looking at the photos taken by the spy satellite, Zhao Changxing, Wu Qinghong and others all had smiles on their faces.
Everyone knows that it is impossible to rely on this attack to achieve the result of completely wiping out the deep space civilization base cluster. After all, the electromagnetic gun projectile is too small, and its main function is to destroy, not destroy.
But even if these psychological preparations were made in advance, the results of this attack were still somewhat unexpected.
In the satellite images, people can clearly see the large fractures and large gaps in the base cluster, and even directly captured pictures of gas leaks and internal fires inside the base.
You know, even at this stage, spy satellites can only get close to the deep space star at a distance of no less than 60,000 kilometers, and even this distance is risky.
However, at a distance of at least 60,000 kilometers, fire and gas leaks, as well as fractures and gaps can be directly photographed. What does this mean?
This means that even from a macro perspective, the damage to those base clusters can be directly detected at this moment!
This attack destroyed at least half of the deep space civilization bases. The remaining half were also damaged, and they will definitely need to spend endless energy to repair them in the future.
Looking at these pictures, even Zhao Changxing felt a little scared at this moment.
"Fortunately, fortunately, it was us humans who launched this form of attack on deep space civilization first, and not the other way around. Otherwise, our losses would have been heavy..."
At this moment, at the beginning of the design and construction of various space bases of human civilization, such as the Spark spacecraft, roller bases, air-space interactive bases, etc., no consideration was given to what to do if attacked. Their outer wall armor is generally only
With a thickness of up to a few decimeters, the material is mainly considered for functions such as radiation protection and thermal insulation.
It is no exaggeration to say that they are "thin skinned and big filling".
Armor of this thickness can protect against the impact of small meteorite particles, interstellar dust, and space debris, but it is absolutely unreasonable in the face of war weapons.
Zhao Changxing turned his head and looked at Wu Qinghong and the other members of the war committee.
"We can't always think about us attacking others without considering the possibility of others attacking us. Maybe one day, deep space civilization will use the same method to deal with us. If that happens, what should we do?"
The committee members and officials were all smiling a moment ago, celebrating the huge results of this attack. But at this moment, after thinking about it for a moment, cold sweat broke out on their faces.
If, if this time, our human civilization is attacked to this extent, then, then...
It is certain that the Fire spacecraft, the drum base, the air-space interaction base, the space scientific research base, etc. will all be destroyed without mercy. The tens of thousands of babies, young children, and teenagers living in the Fire spacecraft and the drum base will all be destroyed.
They will all die, and all ground facilities will also suffer heavy losses. Countless people will die, countless facilities will be destroyed, and human civilization will completely lose its corresponding space transportation capabilities.
Moreover, human beings will lose any ability to replenish the population in at least 30 years. Because all space bases have been destroyed, there is absolutely no way to rebuild them in a short time. After the bases are rebuilt, embryos can be cultivated for them
It takes 30 years to grow up and reach adulthood.
And, the most critical question is, if human civilization suffers such a blow, then... will the enemy give human civilization such a long time to rebuild itself?
Just thinking about that situation makes people feel hopeless.
"The attack on deep space civilization cannot be relaxed." Zhao Changxing immediately made arrangements: "In the future, hydrogen bomb attacks will continue, and projectile cluster attacks will also continue. We cannot give deep space civilization any breathing space. We cannot
Give them a chance to launch a counterattack against us. At the same time, the war committee must immediately study ways to deal with projectile cluster strikes. This is our most important task at the moment and we must not relax."
The tragic situation of deep space civilization has provided an early warning to human civilization. This can probably be regarded as another gain of this attack.
"yes."
Faced with this problem, no one dares to neglect it.
"We speculate that the inheritance of deep space civilization has been discontinued, and our human civilization is not the same." Zhao Changxing sighed silently in his heart: "I should have considered the method of preventing projectile cluster attacks from the beginning, but it was not until
I just thought about it now.”
This so-called chronology is not the chronology of knowledge, because all the knowledge of human civilization is recorded in Xiaoxi's database. This chronology is the chronology of ideas, talents and systems.
If those war theorists, thinkers, strategists and others on Earth were still alive, they would have been able to surmise the existence of this offensive method as soon as they discovered the existence of the enemy and make arrangements in advance.
Unfortunately, they are all gone. Their knowledge has been passed down, but their ideas have not.
"Fortunately, we still have time to grow slowly."
Under Zhao Changxing's order, while human civilization continued to carry out large-scale construction, it also held an extensive discussion. Finally, after summary analysis and refinement, a plan was placed in front of Zhao Changxing.
"Regarding the defense of bases on the planet's surface, the first thing that needs to be done is the establishment of a deep space early warning system. The deep space early warning system can detect large targets such as interstellar missiles and combat spaceships in advance, and guide the next interception action. There is nothing to say about this.
Yes, because we have been doing this. As for the attack methods such as projectile clusters, which have the characteristics of large number, fast speed, small size and low quality, and no possibility of interception, the only way we can deal with it is to strengthen our own defense.
, fight hard.
It is not feasible, practical and economical to rely on increasing one's own armor to complete defense. It is completely unimaginable that any building must have armor with a thickness of at least one meter. Then, the only way to improve defense is
There is only one thing left, that is, all buildings are built underground, relying on the thick rock formations of the planet itself to complete the defense against high-speed projectiles.
According to calculations, in the face of a micro projectile with a kinetic energy of 150 kilojoules, the thickness of a rock layer composed of various elements and compounds, such as tholin, dry ice, silicon oxide, etc., must reach at least 4.39 meters to achieve a higher level.
Defense. Under safe conditions, the thickness of the rock layer should reach about 8 meters. Considering the ground-penetrating missiles that may be faced in the future, special projectiles designed to penetrate rock layers, we believe that the thickness of the rock layer should reach about 20 meters before the threat level can be reduced.
Reduce it to the point where it can be ignored.”
Zhao Changxing pondered slightly.
He knew very well that in the original earth era, the ground-penetrating missiles developed by people could even penetrate hard granite rock formations or reinforced concrete fortifications with a thickness of up to 100 meters. Faced with this kind of weapon, a thickness of 20 meters was obviously not enough.
What kind of.
However, he knew that the main defense targets of the 20-meter thickness that the committee members were talking about at the moment were micro projectiles and small, fast ground-penetrating missiles. Large ground-penetrating missiles could be classified into the same category as interstellar missiles, and they could be defended against them.
They are planetary defense systems, deep space surveillance radars and anti-aircraft electromagnetic guns. Normally they have no chance of hitting the ground.
What made him ponder was the cost of building an artificial structure 20 meters underground.
Compared with constructing factories, workshops, and bases on the ground conveniently and quickly, building buildings underground will undoubtedly require several times more time, energy, and resources.
But he soon made up his mind.
For safety, it is worth paying any price.
"Issue a human government order. From now on, all ground buildings under construction will be stopped and moved underground. In the future, all land-based buildings, all built on the surface, will not be approved unless it is truly necessary to be approved by the human government.
.All above-ground buildings that have been built now, including Human City, Earth City, and Sun City, must begin to formulate demolition plans. In the future, after enough underground cities are built, all these above-ground buildings will be demolished and all building materials will be recycled.
Repurpose.”
"yes."
After finalizing the land-based matters, Zhao Changxing once again looked at Commissioner Wu Qinghong who made the report.
"What about the space base?"
Commissioner Wu Qinghong had a look of guilt on his face.
"After our research, we confirmed that with our current technical means, it is basically impossible to complete the protection of the space base. The only thing that can be done at present is to build emergency shelters in the core of the space base.
There are only two methods to increase the number of layers inside the space base. But... the purpose that these two methods can achieve is only to ensure the safety of personnel in extreme circumstances, and the base cannot be saved."
Zhao Changxing was obviously not satisfied with this result. Not only did he want to save his people, he also wanted to save his base.
Just kidding, which space base was not built with a lot of hard work, and which one can be destroyed just by destroying it?
But he also knew that Commissioner Wu Qinghong must have sufficient basis to support his judgment. Otherwise, he would not say it in front of him.
After thinking for a moment, an idea suddenly flashed through Zhao Changxing's mind.
"Is there really no way, or is there a way but we didn't think of it, we'll find out when we try it."
Zhao Changxing stood up, and his expression became serious again: "Order, launch a projectile cluster attack against the deep space civilization again. Let the deep space civilization help us think about how to deal with this attack. If they can't figure it out, we will keep attacking.
