Zhao Changxing hurried to the combat readiness and defense room and saw the target with his own eyes.
No matter which data you look at, it should be a missile. Its relative speed has now reached almost 17.2 kilometers per second, and is still increasing. At this moment, it is far away from the surface of Sedna.
There are less than 250,000 kilometers left.
A cool air came from Zhao Changxing's back.
With almost no need to think, Zhao Changxing knew that he had been fooled.
Since it was confirmed that intelligent life is very likely to exist on the planet 221SN1, Xiao Xi has monitored this planet more closely. Under this situation, more information has been monitored by Xiao Xi.
It is precisely because of the continuous flow of information that Zhao Changxing believes that the intelligent lifeforms living on that planet should not be aware of his own existence. The reason is very simple. If they are aware of their own existence, how could they possibly
Not enforcing maximum radio silence?
Just like myself, when I heard the first message, I decisively implemented maximum radio silence.
But now it seems that this is a strategy for them to paralyze themselves. It is very likely that they have discovered their existence long ago, but in order to prevent themselves from knowing it, they still allowed themselves to monitor them, and then secretly launched a
The missiles came over, trying to achieve the effect of a sneak attack.
This missile may have been flying in space at a low speed for several months - after all, the distance between Sedna and 221SN1 is as high as more than 60 million kilometers. After approaching the target, the missile
The missile immediately started accelerating with maximum power, trying to strike with thunder and kill the enemy with one strike before our own side had time to react!
No, not one!
While Zhao Changxing was thinking quickly in his mind, the deep space monitoring network consisting of more than 800 ground-based and space-based deep space radars observed the target again!
There are five missiles!
If these five missile warheads are loaded with hydrogen bombs - the yield does not need to be too large, 10 million tons of TNT is enough, and they hit the Sedna star and detonated successfully...
This is enough to cause earth-shaking changes on Sedna. It is certain that the strong crustal vibration caused by the explosion will destroy all man-made structures on Sedna.
If the design of a three-phase bomb is adopted, that is, a layer of fissile material is wrapped in the outer layer of the hydrogen bomb, the explosion of the hydrogen bomb will also throw radioactive pollutants onto the entire planet. By then, even if there are survivors,
, I am afraid that it will also be fatally affected by radiation sickness, and it will be impossible to even rebuild civilization again!
Without the supplement from the ground, even if the Spark spacecraft escaped the impact of the violent charged particle flow caused by the hydrogen bomb explosion in space, all the tens of thousands of minors living inside would starve to death.
This is undoubtedly a civilization-destroying disaster.
Several members of the war committee hurried over, looking pale and at a loss.
Zhao Changxing looked livid, but still maintained his composure.
The long journey of life has made him experience too much. This allows him to remain calm no matter what the situation.
"Leader, do you want to issue an emergency evacuation order?"
Zhao Changxing shook his head: "It makes no sense. There are so many people, there is no place to hide, and there is no time to hide. The only thing we can do is to destroy them. Order all electromagnetic guns to activate immediately and try to destroy the target!"
We have electromagnetic guns! We also have electromagnetic guns. It’s not like we can’t do anything!
Several committee members left in a hurry. Zhao Changxing sat in the combat readiness and defense room to coordinate the overall situation.
After a slightly flustered operation, it took a full hour to prepare the electromagnetic guns installed all over the Sedna planet. At the same time, because of the angle, only the ones who could intercept these missiles were
106 units.
For a regular army, such delay in action is unforgivable. But now, Zhao Changxing can't blame people too much.
"Reporting to leader, electromagnetic gun No. 1 has locked target No. 1!"
"Electromagnetic gun No. 2 has locked target No. 3!"
"We have locked target No. 5!"
During the period of pre-war preparations, the deep space surveillance radar did not detect any new missiles. This of course does not mean that there are really no more missiles. It may also be that the performance of the deep space surveillance radar is insufficient, the quantity is insufficient, and there is no new missile.
It's because the fish that slipped through the net were found. But there's nothing we can do about it.
"fire!"
Amidst the low buzzing sound, small projectiles with a mass of only 0.5 grams began to accelerate in the vacuum electromagnetic orbit. 30 seconds later, 106 projectiles rushed out of the barrel at the same time and headed into space, still 20 meters away from us.
The goal of tens of thousands of kilometers is dashed away.
When aiming at a target, people certainly need to consider the lead time. In addition, the communication delay caused by the upper limit of the speed of light also needs to be considered.
At their speed, they will encounter this missile, which is seriously suspected to come from the planet 221SN1, in about two hours, and hit them.
But during this period, people will not choose to just wait.
To hit such a tiny target at such a long distance is even more difficult than reaching the sky. This requires the launch angle of the electromagnetic gun to be incredibly precise. And now, the electromagnetic gun made by people is obviously
Not so precise.
Even if the accuracy is sufficient, the trajectory of electromagnetic gun projectiles flying in space also has a certain degree of random deviation. Because in space, interstellar dust, planetary gravity, various high-energy radiation, and even high-energy charged particles from the sun will cause
It has a slight impact on their forward trajectories. Once the distance is long enough, the initial small gap will always be magnified to a point that cannot be ignored.
Those interstellar missiles flying towards Sedna are only 4 meters in diameter and 20 meters in length. If they deviate slightly, they will miss the target.
Even Zhao Changxing had to admit that luck was the most important determining factor in whether one's own projectiles could intercept those missiles.
Luck cannot be controlled, so...the key to improving the success rate is quantity.
As long as the number is large enough, no matter how low the probability is, you can always encounter it.
"Lock again, fire again!"
"Continuous firing!"
All 106 electromagnetic guns have entered full power operation mode. In the automatic locking mode, every time a projectile is fired, the console will immediately start locking for the second time and launch the projectiles to the calculated encounter point.
An electromagnetic gun can fire two projectiles per minute. 106 units is 212 rounds. And now, the continuous firing has lasted for more than two hours.
A total of nearly 30,000 projectiles have been fired.
At this moment, except for a small number of people, people on the entire Sedna planet, including the Spark spacecraft, are still continuing their previous life trajectory. They are either working, resting, playing, or eating.
sleep……
No one can realize that civilization has reached the edge of life and death.
At this moment, the projectiles fired for the first time were almost meeting those missiles.
But in the radar monitoring network, those missiles still exist.
Obviously, the projectile failed to hit the target.
"Don't worry, we still have a chance."
Zhao Changxing comforted people in a deep voice.
Time passed slowly amid anxiety and heaviness. Suddenly, a "sun" appeared in the dark night sky above the star Sedna.
The light it released was so bright that it illuminated the entire land in an instant. People in the wild looked up in shock and felt their eyes sting.
"Target No. 3 was destroyed!"
It exploded tens of thousands of kilometers away from Sedna. At this distance, it would have basically no impact on Sedna.
After continuous attempts, one target was finally destroyed. But Zhao Changxing's heart became heavier and heavier.
"Judging from the explosion results, the warheads of these missiles are indeed hydrogen bombs! The yield is at least 12 million tons of TNT! They even have a damage-to-destroy mechanism!"
"All missiles must be intercepted, and not one of them can be hit!"
The 106 electromagnetic guns were still firing projectiles at full power. At this moment, there was less than an hour left before they hit Sedna.
"Target No. 2 was destroyed!"
The No. 2 missile did not explode successfully. This may be because it was damaged too quickly and too much, and the damage-and-destruct mechanism failed before it had time to take effect.
"Target No. 1 is destroyed!"
"Target No. 5 was destroyed!"
The destruction of Missile No. 1 and Missile No. 5 once again activated the damage-to-destruct device, briefly illuminating the land of Sedna.
At this moment, everyone who was still awake realized something. An uneasy feeling was quietly spreading.
At this moment, Zhao Changxing's broadcast reached everyone's ears.
"We have been attacked by enemy missiles. But don't worry, we have the ability to intercept them. Now, everyone, stay calm and don't panic."
Zhao Changxing's voice is always so calm, and it always contains a reassuring power.
In the combat readiness and defense room, one committee member was almost crying at this moment.
"Leader, target number four has not been destroyed yet! In another 20 minutes at most, it will hit us!"
"It has accelerated to its maximum speed, 25 kilometers per second!"
"The performance of deep space radar is limited, and there will be errors when searching for such a high-speed target!"
The electromagnetic gun projectile originally relied on luck to hit the target. Now, due to errors in deep space radar, the probability of hitting the target is even lower.
Zhao Changxing took a deep breath.
"I order all flame-type spaceships to take off!"
After decades of accumulation, human civilization now has a total of about 200 flame-type aerospace transport ships. Now, they all take off at maximum power and fly crazily towards the trajectory of the missile in the calculation.
Advancing at this speed, they will quickly consume all their fuel. Even if they survive, it is impossible for people to recover them.
They will rush into deep space without looking back and never come back.
