The so-called metallic hydrogen is actually a special state of existence of the hydrogen element.
Under extremely high pressures—higher than those at the Earth's core—hydrogen gas transforms into a solid, taking on metallic properties and becoming superconducting.
At the same time, because of its extremely high internal energy, metallic hydrogen has an extremely high energy density, even more than 30 times that of TNT explosives.
Generally speaking, although it can exist stably at room temperature, it is easily affected and becomes metastable, or even explodes with a bang.
However, if some technology that humans have not yet mastered is used to make its existence form more stable and controlled, then some very interesting things will happen.
That is, it has the potential to become an explosive and electromagnetic dual reactive armor.
First of all, metallic hydrogen has extremely high energy inside. Through some special designs, it may be designed to "explode in a small-scale controlled manner once it is attacked by an external attack." Then, through its own explosion, it can blow up external projectiles.
open, or weaken its kinetic energy.
This is explosive reactive armor.
Secondly, metallic hydrogen has superconducting properties. This property allows it to have an effect similar to an "electromagnetic coil", actively reducing the speed of foreign metal projectiles through its own electric field.
This is a new type of electromagnetic reactive armor.
In addition, through some special technology, its existence form is extremely stable and extremely tough - even far surpassing some special alloys. The combination of the three gives it an ultra-high defense power that is unimaginable by human scientists.
This is the reason why they can remain unaffected in such a chaotic battlefield.
Li Dajiang looked at the military scientist.
"If it's metallic hydrogen, what can we do to break it?"
The scientist's voice trembled slightly: "It can only be consumed. Through its explosive reactive armor characteristics, every projectile that hits it will cause the explosion of a small amount of metallic hydrogen, which is equivalent to consumption.
Part of its armor. If enough projectiles hit it, no matter how much metallic hydrogen it is, it will be consumed."
"How many pellets do you want?"
"I don't... I don't know. Or, or through high explosives, no, high explosives should not be enough, nuclear bombs, atomic bombs or hydrogen bombs will do."
At present, humans simply do not have the ability to project nuclear bombs to accurately hit the enemy in such a chaotic battlefield.
Li Dajiang turned his head and stared at the radar screen, his expression becoming serious again.
It seems that it is impossible to quickly defeat these enemy ships and quickly destroy them.
But the worse situation is obviously yet to come.
He noticed that the rate of damage to his own spaceship suddenly increased.
In the past few days, a total of less than 100 combat spaceships were damaged in battle. And the reason for the battle damage was mostly due to bad luck and being hit by stray bullets.
But now, since less than 200 enemy combat spacecraft appeared, more than a dozen spacecraft have been destroyed in less than an hour!
Before a spacecraft was destroyed, a picture captured caught Li Dajiang's attention.
In that picture, there is a small bright spot that is almost undetectable.
After enlarging and repairing it, Li Dajiang saw the true appearance of that small bright spot.
That's not an electromagnetic gun projectile.
It's a missile.
A miniature missile not exceeding 3 cm in diameter and 13 cm in length.
This kind of missile cannot even be called small, it can only be called micro.
"How come there are such small missiles? How can they speed up without enough propellant? If the speed is too slow, why can't our spacecraft intercept them?"
But the next moment, Li Dajiang figured it out on his own.
It must be electromagnetic acceleration technology again.
Directly through the electromagnetic gun launch pad, just like launching electromagnetic gun projectiles, this micro-missile is launched directly, so that as soon as it appears, it will have extremely high speed.
If the small missiles launched by the big spaceship before were actually intercepted due to being destroyed by stray bullets because of their large size, there is almost no possibility of interception for this kind of micro missiles.
As long as I'm small enough and fast enough, no stray bullets can hit me.
"Judging from the type of explosion, the warhead of this miniature missile must be loaded with antimatter."
Even if a micro missile warhead can only contain 0.01 grams of antimatter, the energy it releases will be equivalent to the energy released by the simultaneous explosion of hundreds of tons of TNT explosives.
This is undoubtedly enough to destroy a spacecraft.
"It's not just micro missiles." The scientist said in a hoarse voice: "There are also ultra-high-speed electromagnetic guns, laser cannons, and electromagnetic pulse bombs..."
If you fight, your side will not be able to break through the opponent's defense in a short period of time.
Defend, you can't defend. Whether it's micro-missiles, electromagnetic gun projectiles, or laser cannons, they can destroy your own side relatively easily.
Run, you can't run away. The enemy's combat spacecraft obviously has more maneuverability than our own.
Li Dajiang knew very well that at this moment, the big spaceship was still in an extremely weak stage. However, his own side was unable to withstand even the enemy's weak counterattack.
The crushing strength among civilizations of different levels is so obvious. Is it so serious?
If the opponent is at its peak, how high will the opponent's combat power be?
The situation on the battlefield reversed in a very short period of time.
Li Dajiang looked stern and slowly issued the latest order.
"From now on, get as close to the opponent as possible and launch missiles at a relatively close distance to attack the opponent."
If the distance is closer, it will reduce the possibility of one's own interstellar missile being destroyed by stray bullets. Although this will also cause the interstellar missile to be unable to reach a higher speed - after all, one's own side does not have electromagnetic acceleration technology, which makes the missile easily intercepted by the opponent.
But, give it a try.
Give it a try, this is the last chance for human civilization.
"What kind of spaceship is this?"
At this moment, Li Wenying felt slightly desperate.
When these combat spaceships first joined the battlefield, Li Wenying, who was on the front line, had already noticed something unusual about these spacecraft.
Their firepower is too fierce, their defense is too strong, and their mobility is ridiculously strong.
Until now, only one such spaceship has been destroyed by a large amount of fire from our own side. However, during this period of time, more than 30 of our own spaceships have been destroyed by enemy spacecraft!
An exchange ratio of one to thirty!
How can we fight this battle?
In particular, we must continue to maintain pressure on the big spacecraft. Once the pressure there is reduced, the enemy is likely to launch the extremely destructive and extremely high-speed interstellar missile again, and at the same time, the laser
Cannons will also be free to launch attacks.
At this time, Li Wenying received the order for close combat.
Melee combat, translated, means you have to pay for your life.
"If there is really no other way, the only choice is to risk your life!"
Li Wenying has no fear of death. He even knows that every soldier has the determination and will to die generously for civilization at any time.
Because there is no retreat for human civilization.
"Then risk your life!"
In this moment, the combat spacecraft on the side of human civilization showed a more fearless and more crazy attitude.
The enemy's spaceships did not seem to adapt to this battle rhythm. After changing the fighting style, Li Wenying saw through the real-time battle report that three enemy spaceships were destroyed in a short period of time.
This is undoubtedly an extremely high efficiency.
However, he also saw that in this very short period of time, more than 50 spaceships were damaged in battle.
In spaceship No. 32, looking at the fierce and fearless enemy, Iloben felt a little scared in his heart.
This is different from what is taught in the book...
We are all inferiors. We are all executing the orders of our superiors. We just have to do whatever our superiors say. Why do we have to work so hard?
Just like the commanders of the Moyun Litar civilization, they would never issue such desperate instructions. Because they know very well that others do not have the courage. Even if they are forced to do it, the tactical movements and other actions will definitely be deformed.
But now, no matter where it looks from, the enemy is actively executing this tactic...
It's like they don't care about their own lives at all and are completely willing to die.
Iloben looked at his teacher with some doubts, and saw that Wirzben also had a face full of doubts.
At this moment, Villagash received a piece of good news in the main control room of the Okaro spacecraft.
"Report to the captain! We found that there is a fault in the vacuum cannon and there is no need to replace spare parts. It can be restored to normal with a simple repair! It is expected that the vacuum cannon will be repaired in another 3 hours!"
This time is several days ahead of schedule.
Such good luck made Villagash almost jump with excitement.
Vacuum cannon! That is a super weapon developed by countless scientists of our own civilization!
Although the Okaro spacecraft is only an armed mining ship, not a battleship, so the vacuum cannon it is equipped with is only a three-line small-yield vacuum cannon, but even so, it must be completely sufficient to deal with these damn native civilizations.
!
Based on its range attack characteristics, you don't even need to accurately grasp the coordinates of the enemy's space carrier to destroy it with one shot! And without the space carrier, how can you fight?
At this moment, Li Wenying's spaceship was still attacking the enemy without fear of death. However, this impact did not seem to be able to completely reverse the situation.
Although our side has gained many victories, our casualties have been too great.
I'm afraid an offensive of this level won't last long and will be forced to stop.
Until then, until then...
A hint of despair slowly rose in Li Wenying's heart.
He even turned on the broadcast communication system irrationally and started yelling at the top of his lungs: "You are just sub-humans, why are you so loyal to Moyunli Tal? Isn't it great to be sub-humans!"
