Chen Chen continued to explain the spacecraft's protection system:

"These two basic shields are actually just the effect of a reactor. If two redundant reactors are also used as protection systems, then two layers of active shields, two layers of passive shields, and a total of six layers of energy shields.

"If the six-layer shield is fully opened, even if it is the strongest nuclear bomb in the history of the earth, Ivan directly explodes on it, and the internal personnel and equipment will be intact...

"You know, when the energy shield is forcibly broken, it is actually just that the shield's energy replenishment cannot keep up with the consumption. Unless all shields are broken, the shield generator itself will rarely be truly damaged. Once the energy supply is restored, the shield will be supported again.

"If the enemy plane breaks through the first shield, but before continuing to break through the second shield, the first layer of shield is likely to have recovered. Then, once the two layers of shields are clamped, the enemy plane will be completely ruined.

"In addition, these shields are almost 100% invisible to Earth Technology. Even if they are directly driven 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 at the scene became more and more strange. A group of people bulged their eyes and looked at the big screen on the stage without blinking. No one spoke for a long time.

They didn't know what to say. The previous introduction to combat power had left everyone speechless. Now this protective power is speechless.

Mr. Wu couldn't control his emotions and asked subconsciously:

"But I really can't understand why they have to make such a high-intensity protection system? According to such an algorithm, their own planes cannot break such a shield. How should they fight in the battle between them?"

Mr. Wu’s doubts were also the doubts of most of the people present. They did not understand why these aliens wanted to build defense power to this level without increasing their attack power.

If you spend time studying these technologies and using them to design fighter jets, you will definitely be able to break such shields.

Looking at everyone's doubts, Chen Chen smiled and shook his head: "Now everyone's questions are here. I said before, long-distance and ultra-high-speed space navigation, shields are more important than spears. Now I will explain the reason.

"Actually, it's a very simple truth. The faster the speed, the more dangerous it is when you hit an obstacle.

"A car hits an apple or a peach pit on the highway and can easily break the windshield, with a power of almost the same as a quilt bullet, while a bird flying in the sky can knock out a big hole in the nose of the plane that is telling the flight.

"Then in the universe, the spacecraft at a high speed of one percent or even one tenth of the speed of light, the destructive power of a particle of dust is immeasurable, let alone meteorites and comets.

"To navigate at high speed and long-term high speed in the universe, you must first survive, so defense capabilities are very critical.

"The outer layer of active energy shield is used to clean up comets and meteorites in front of you. Even if you cannot completely vaporize the target, it will be completely crushed and turned into cosmic dust.

"Then the inner passive shield is used to offset the explosive force generated by the dust impact, which can prevent the spacecraft itself from being damaged.

"The patrol ship we are talking about now is sailing inside the atmosphere, so its shield system is actually shrinking.

"The complete shield generator has more powerful power and more complex structure, and also requires a very large energy supply and a larger volume of spacecraft to be placed.

"For this level of energy shield, the difference between meteorites and comets, aircraft and missiles, is not much different.

"That's why, in this era, the shield is greater than the spear, because the shield is not strong, and if the protective measures are not strong enough, you will not survive, let alone attack others.

"Aircraft is a suicide squad or assault troop to obtain weapons, and they are basically powerless to use spacecraft of this level.

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

"Even if a large-scale suicide attack was used to forcibly explode a layer of shield, this unsustainable attack has no practical significance. As long as the opponent's shield has a chance to breathe, it will be restored soon.

"Then the regular expansion and contraction of the active shield can directly kill all aircraft on a spherical surface.

"In this case, both the aircraft and the Gundam have lost their function. In this era, the weapons that can break the spacecraft, as well as the main gun and secondary gun of the spacecraft.

"The weapons used by the warship are all energy weapons. The attack track is infinitely close to the straight line and the speed is approaching the speed of light. The moment the button is pressed, it can hit the target directly. The opponent has no time to escape and can only bear it.

"No matter how fast the plane flies, it can catch energy cannons that are not as fast as light.

"In addition, because in space, the battlefield is no longer the curved surface of the earth, but a three-dimensional scene, the firing boundary of the main gun of the warship will not be affected in any way and can be fired in all directions.

"It is also almost impossible for the target to find any cover to hide,

"The power of the nuclear bomb, the speed of the machine gun, continues to bombard, causing the opponent's energy shield to be consumed continuously, and there is no time to recover. As long as the attack lasts long enough, it will eventually explode.

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

"So in this level of cosmic warfare, sufficient energy, plus a large enough caliber, that is, the total output that can be generated is sufficiently large, which is the prerequisite for 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 earth now, so they did not conduct detailed analysis and make a project.

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

Some people have also begun to worry about who the real owner of these spacecraft will come to Earth again? Will they discover their things if they crack them like this and then be retaliated against.

During this period, no one spoke, but the preaching meeting still had to continue. After all, what is being said now is just an explanation of the overall situation.

Specific details of the spacecraft, such as liftoff speed, residence time, endurance time, etc.

The technologies involved, spacecraft reactors, energy shields, nuclear energy cannons, etc.

There are many things to talk about, including various functions, reconnaissance and anti-reconnaissance, communication and anti-communication, etc.

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

Further details, technical principles, etc. should be given to the appropriate group of people in the form of explanation documents, rather than in the current method similar to public courses.
