Chen Chen went on to explain the ship's protection system:

"These two layers of basic shields are actually just the effect of a reactor, if two redundant reactors are also used as a protection system, then you can add two layers of active shields, two layers of passive shields, a total of six layers of energy shields.

"If the six layers of shields are fully opened, even if it is the strongest nuclear bomb in the history of the earth, Big Ivan will explode directly on it, and the personnel and equipment inside will be intact......

"You know, when the energy shield is forcibly broken, it's actually just that the energy replenishment of the shield can't keep up with the consumption, unless all the shields are broken, the shield generator itself will rarely really suffer substantial damage, and once the energy supply is restored, the shield will be held up again.

"If the enemy plane breaks through the first shield, but before it continues to break through the second shield, the first layer of shield is likely to have been restored, and then the two layers of shield are clamped, and the enemy plane will be left with no scum.

"In addition, these shields, for earth technology, are almost 100% invisible, even if they are directly opened to the White House, the other party will not be able to detect them at all."

At this point, Chen Chen's introduction finally came to an end, but the atmosphere of the scene became more and more weird, a group of people puffed out their eyes, looked at the big screen on the stage without blinking, and no one spoke for a long time.

They didn't know what to say, the previous introduction of combat effectiveness had left everyone speechless, and now this protective force is also speechless.

Wu Lao couldn't control his emotions a little, and subconsciously asked:

"However, I can't understand why they are doing such a high-strength protective system. According to such an algorithm, their own planes will not be able to break through such a shield, and how can they fight a battle between them? ”

Wu Lao's doubts were also the doubts of most of the people present, they didn't understand why these aliens wanted to pile up their defensive power to this level instead of increasing their attack power.

If you spend the time researching these technologies and designing fighter jets, you will definitely be able to break through such a shield.

Looking at everyone's doubts, Chen Chen shook his head with a smile: "Now everyone's questions are coming, as I said earlier, in long-distance and ultra-high-speed astronautics, the shield is more important than the spear, and now I will explain the reason."

"Actually, it's very simple, the faster you go, the more dangerous it is when you hit an obstacle.

"When a car hits an apple or a peach pit on the highway, it can easily break the windshield with about the same power as a bullet, and a bird flying in the sky can knock the head of a flying airplane into a big crater.

"Then in the universe, at the speed of one hundredth, or even one-tenth of the speed of light, the destructive power of a single speck of dust is immeasurable, not to mention meteorites and comets.

"In order to travel at high speed for a long time in space, you must first survive, so defense capability is very important.

"The outer layer of active energy shield is used to sweep away comets and meteorites in front of it, and even if it cannot completely vaporize the target, it must be completely shattered and turned into cosmic dust.

"Then, through the passive shield of the inner layer, the explosive force generated by the impact of the dust is counteracted, which can also avoid damage to the spacecraft itself.

"The patrol ship we are talking about now is actually shrunken because it is navigating inside the atmosphere.

"A complete shield generator is more powerful and more complex, and it also requires a very large energy supply and a larger spaceship to be placed.

"For an energy shield of this level, it doesn't make much difference whether it hits a meteorite and a comet, or an airplane and a missile.

"That's why, in this era, it's the shield that is bigger than the spear, because the shield is not strong, and if the protective measures are not strong enough, you can't survive yourself, let alone attack others.

"Airplanes are in the nature of death squads and assault troops, and they are basically powerless for ships of this level.

"Because the aircraft is small, the fuel it carries is limited, and the attack power is limited, it is basically a one-time attack, and it cannot cause effective damage to the opponent's warship at all.

"Even if you use a large-scale suicide attack to forcibly blow up a layer of shield, but this kind of unsustainable attack has no practical meaning, as long as the opponent's shield has a chance to breathe, it can be quickly recovered.

"Then a regular expansion and contraction of the active shield can directly kill all the planes on a sphere.

"In this case, both the airplane and the Gundam have lost their effectiveness, and the weapons that can break the ship's weapons in this era are still the ship's main and secondary guns.

"The weapons used by the battleship are all energy weapons, the attack trajectory is infinitely close to a straight line, the speed is close to the speed of light, and at the moment of pressing the button, it can directly hit the target, and the opponent has no time to escape, so he can only carry it.

"No matter how fast the plane flies, it can't catch up with the energy cannon at the speed of light.

"In addition, because in space, the battlefield is no longer a curved surface of the earth, but a three-dimensional scene, so the firing range of the battleship's main guns will not be affected in any way, and it can be fired in any direction in all directions.

"It's also almost impossible for the target to find any cover to dodge,

"The power of the nuclear bomb, the speed of the machine gun, and the continuous bombardment, make the opponent's energy shield continue to consume, and it is too late to recover, as long as the attack lasts long enough, it can finally explode it.

"Of course, if the output of your own energy cannon can't keep up with the output of the opponent's shield generator, you will never be able to break the opponent.

"Therefore, in a cosmic war of this level, enough energy, coupled with a large enough caliber, that is, a large enough total output that can be caused, is the premise of victory."

After listening to Chen Chen's explanation, many people nodded silently, in fact, many people have thought of similar ideas, but they have always felt that the situation is too far away from the current earth, so they have not carried out a detailed analysis and made a project.

Then, everyone was digesting what Chen Chen explained, and then analyzing the impact of the technology on this ship on the future of the earth.

Some people have begun to worry about whether the real owners of these spaceships will come to Earth again? If you crack their stuff like this, will they find out and then be retaliated against.

During this period of time, no one spoke out, but the lecture still had to continue, after all, what was being said now was only an explanation of the overall situation.

The specific details of the spacecraft, such as the speed of liftoff, the duration of the stay, the endurance time, etc.

The technology involved, the implementation of spaceship reactors, energy shields, nuclear cannons, and so on.

There are many things that need to be talked about in various functions, reconnaissance and counter-reconnaissance, communication and counter-communication, etc.

This level of functional explanation lasted for about half an hour, and Chen Chen felt that it was almost okay.

Further details, technical principles, and the like are best presented to the right people in the form of explanatory documents, rather than in the way that they are now explained in a way that is similar to an open class.

So, next, Chen Chen entered the summary time.
