The door of the courtyard house has been welded dead

Chapter 1160 Class
Survived an atomic bomb explosion.

As photos of the scene and statistical data gradually arrived in Beijing.

This time, the leaders have a clear understanding of the destructive power of nuclear weapons.

In a rather mysterious conference room, there are no windows at all. When the lights in the room are turned off, slides are projected by the projector onto a special screen wall and appear clearly.

The glassy dust and deep pit at the center of the explosion looked so small when people wearing protective clothing stood on the edge.

Not only the depth, but also the width of the sunken ground is extremely amazing.

The tanks, which had been specially transported from afar, had moved more than ten meters after being lifted from their designated positions. In the photos taken to measure the distance, the steel torrent with only wreckage left looked like burnt sweet potatoes.

"The equivalent of the explosion is between 22,000 and 25,000 tons of TNT, which is 2,000 to 5,000 tons higher than expected~?"

The next photo shows the locomotive and carriages that were lifted off the track and the shattered fighter jets, all of which show that the power of the explosion was extraordinary.

The leaders holding the materials in their hands read them carefully and looked at the photos on the screen seriously like students. One of them even asked a question.

Originally they thought that it would be good enough if it could explode, but now they see that the released equivalent is even greater than originally planned, with an extra quarter of power. They don't know whether it is a good thing or a bad thing for them.

"Yes~!"

"According to my guess, it may have something to do with the mid-air detonation. The height of the hoisting tower is ** meters, and the release of energy has achieved the best effect without any intervention from the ground~!"

Putting the microphone in front of him to his mouth, Lu Guangda, dressed in formal attire, no longer had the "down and out look" he had when he was in the Northwest.

His eyes were extremely sharp, and his voice was transmitted throughout the entire conference room through the microphone. However, the guards standing on duty outside the door could not hear a single sound from inside at this time.

"The higher the altitude, the stronger the explosion. If that's the case, if we use fighter jets to deliver the bombs and detonate them at a higher altitude, will the effect be better?"

By analogy, if the energy released is close to the ground, it will be partially absorbed by the ground. So the farther and higher it is, the louder the explosion will be, right?

The person asking the question could see a hint of blue in the flickering lights. The fact that he could ask this question in such an occasion naturally represented his branch of the military.

"Not entirely true~!"

"The energy release process also requires the participation of the ground. Please play the video of Ground 13 so that everyone can see the detailed process~!"

"Yes~!"

Hearing Lu Guangda's call, the projectionist hurriedly placed the instructions with the internal number on the projector. On the outer casing of the projector, the words "Top Secret" were printed in bright red fonts, which made people who saw it feel awe.

"Swish, swish, swish~!"

After the projector idled for a few times, it rotated the film smoothly. With the projection of special lights, the scene of the explosion appeared in the camera, and snowflakes flashed from time to time. It seems that the radiation has a significant impact on the video recorder.

The fireball exploded instantly, and even with a long-distance camera, it could be seen clearly. The shock wave generated by the explosion then swept the surroundings in the shape of a circular cover. The energy field, which was so overwhelming and destructive that it directly destroyed the test objects and test buildings on the ground!

When the invisible energy field becomes visible and observable, it means that the energy it releases has reached its peak.

"Slow down here, slow down a little more~!"

Lu Guangda held the microphone and directed the projectionist to play the video, and would stop it immediately when a specific ideal photo was shown.

"This is the process of energy release. Normally, it's called a shock wave. Professionally, it's called a blasting circle. It refers to the expansion force and shock wave generated when explosives explode, which spreads out in concentric circles from the center point to the surrounding areas~!"

"Its circle, from the inside to the outside, is actually divided into several layers. I won't introduce them one by one. You just need to know that the pressure release is basically complete when it reaches the third circle, called the crack circle. The destructive power caused by the final vibration circle is very limited~!"

Holding a pointer in his hand, Lu Guangda walked to the front of the screen and drew several circles of indicated sizes on the picture of the shock wave with the tip of the pointer. When he drew the third circle, he knocked on the screen and then began to explain.

"If we choose to detonate at high altitude, the blasting circle can be maximized if the altitude is too high, but the destructive power to buildings, equipment, and even personnel on the ground will be minimized because the energy scatters in all directions. By the time it reaches the ground, the first two circles will have been released in advance~!"

The reason is obvious. The explosion of an atomic bomb does not mean the higher the better. The height is limited. If you want to release energy to the ground, the participation of those near the ground is still needed.

This is a vivid image, teaching the leaders of various troops. Although the atomic bomb has been developed, there are too few people who know about it. This is also one of Lu Guangda's tasks in Beijing. "I understand, but what is the best detonation height? Has it been calculated yet?"

When the Air Force heard that the power was reduced after the high-altitude explosion, they smacked their lips, feeling very uncomfortable, and asked unwillingly.

"There is no best. The destructive power of an atomic bomb is not limited to the tangible aspects. As for the destructive power on the ground, according to our calculations, detonating it at an altitude of about 600 to meters can maximize the destructive power on the ground~!"

Without even flipping through the notebook, Lu Guangda memorized everything in his heart. This was the value of the information in this era. Any data would be engraved in his mind after just one look.

"Oh~, what do you mean by invisible?"

The other leaders became interested at this time. They didn’t expect that the atomic bomb had other uses in invisible places~!

"Electromagnetic interference, near-ground explosion, the degree of destruction on the ground can be achieved to the best extent, but high-altitude detonation also has its advantages. Comrade projectionist, please play video number 24~!"

It was still the same procedure. The conference room was dark for a moment and then lit up again, but this time, it was not the magnificent scene of the shock wave raging during the explosion, but inside the house.

On the long table were various machines, wires, even radios and telephones used by the army, and many other miscellaneous items.

Without exception, these machines were disassembled, and the electron tubes and civilian transistors inside showed that their internal structures were extremely complex.

"The next thing to talk about is the impact of electromagnetic interference on equipment~!"

"Choosing a high-altitude release also has its unique advantages. After the atomic bomb exploded, the communication facilities of the test base were completely paralyzed in a short period of time. Among them, the most serious was the radio communication system, that is, the radio station~!"

"Nuclear electromagnetic pulse is a strong electromagnetic wave generated during an explosion. It can instantly generate extremely high voltage and strong current, causing damage to electronic instruments and electrical equipment, and then causing command, control, communication and other systems to malfunction~!"

After knocking on the curtain, I found out that it was not that the radio station was unusable, but that the electronic components inside were burned out. It could not even be started, let alone sending or receiving messages.

"The one that was less affected was the tube telephone. It was the only one that could still contact the switchboard under the circumstances at the time, but the quality of the communication was still severely affected~!"

"This is the situation near the ground. According to calculations, if we choose to detonate at a high altitude of 5000-10000 meters, the power of the nuclear electromagnetic pulse will increase exponentially~!"

Lu Guangda's expression became unusually serious at this moment. He was not joking, but the released energy field could really do it. Compared with simply destroying the ground, this invisible destructive power was even more astonishing.

"Geometric multiples?"

"Yes, one hundred kilometers, three hundred kilometers, the higher the altitude, the more likely it is that it will cover a range of thousands of kilometers, causing the power system to fail and electronic components to burn out~!"

If possible, Lu Guangda really doesn't want this broken planet to have dangerous things like nuclear weapons. Electricity is the light of civilization, and the atomic bomb is too dangerous. Once used too hard, the light of civilization might be extinguished by our own people~!

“Oh my god~!”

"It's so incredible~!"

After Lu Guangda finished speaking, everyone below felt the genuine shock. Over thousands of kilometers of land, electronic equipment was destroyed and communications were cut off. The situation in rural areas was still relatively okay, but in urban areas, without electricity, it was hard to imagine what the situation would be like.

Once the factory loses power and stops production, we won’t be able to fight back, let alone produce weapons to fight back~!

"According to my understanding, when the destructive power to personnel is the greatest, the destructive power to electronic equipment is the smallest. When the destructive power to electronic equipment is the greatest, the scope of killing personnel is the smallest~!"

Someone immediately raised his hand to ask a question. After thinking for a second, Lu Guangda nodded.

"You may think so, next one~!"

"Why are vacuum tube telephones less affected in the same scenario? Is it because the nuclear electromagnetic pulse has limited impact on vacuum tubes or something else? As far as I know, the Soviet Union has strengthened its research on vacuum tubes. Is it because of this consideration?"

Lu Guangda hesitated for a few seconds. He was studying abroad in Da Piaoliang and didn't know much about the Soviet Union. Moreover, when he arrived at the base, that group of people were already in a hurry to withdraw, so he was not very clear about this area.

"That may be the reason. We still need to study why the electron tubes were not burned by the pulses. But it doesn't mean that 100% of them were not damaged. Many electron tubes were damaged in this test~!"

The electron tube has its advantages, and the transistor has its advantages. Lu Guangda doesn’t want to explain anything about this for the time being. After all, this is the first nuclear test~!
