On April 5, 1945, around the Qingming Festival, during this drizzling season, the god of death appeared over Japan. Paul Tiberts flew over Hiroshima in the aerial fortress Enola Gad.

At 8:15 am local time in Japan, Pandora's magic box opened at a height of 9ooo meters. When the little boy landed staggeringly to an altitude of about 55o meters, the fuse on the bullet began to work, and soon a fireball appeared in the sky. After a few milliseconds, the fireball continued to grow and finally evolved into the second sun in the sky.

This artificial sun burned the vast ocean, and the high pressure of the explosion shock wave attracted the power of the mountains and tsunamis. The wind and shock waves of sound spread outward, destroying all the buildings they encountered like they were pushed to blocks.

After the storm, there is a ruthless high temperature, which is released in large quantities within 3 seconds after the explosion. The ability to release is simply imagined. The explosion center area is about 1 oo calories per square centimeter, 56 calories within 5 oo meters, and 1 oo calories within 1 oo meter. In other words, the energy received by the ground is equivalent to 1 or oo times that of ordinary sun. The temperature in the explosion center reaches 3, oo 4, and ooo high. The tiles and other houses near the explosion center "bubbles" one after another, and the wooden houses automatically ignite when they reach the ignition point.

Of course, these are not the most terrifying. What's even more terrifying is that the sun radiates countless deadly rays, and the explosion emits a large number of a-rays, b-rays, gamma rays and neutrons. It is estimated that there are 1.2 trillion high-neutrons and 9 trillion slow-neutrons (hot neutrons) per 1 square centimeter on the surface. Although it is not as awesome as the later neutron bullets, almost no one can escape the attack of this neutron rain in the core area of ​​the explosion. Especially considering that most of Japan's traditional buildings are wooden structures, their ability to resist neutrons is even worse.

Paul Tibetz flew away quickly in the aerial fortress Enola Gad. He didn't know that he had created a world discipline and he might become the most murderer in the world. When the little boy exploded, at least 70,000 residents of Hiroshima died directly, and in the next decade, the later effect of the atomic bomb could kill at least 100,000 people.

Of course, the spectacular scene of the explosion was also recorded by the US Air Force who were watching from afar. They will use photos to show the world the terribleness of nuclear weapons and the power of the United States. Anyway, when Washington was informed of the successful explosion in a few minutes later, the White House and Capitol Hill cheered.

According to the arrangement of the United States ****, the photos on the scene will be sent to major media as fast as possible, and the photos of the destroyed Hiroshima will be sent to the media as fast as possible. After that, the United States can show its might to the world and make the Soviet Union honest.

Of course, Roosevelt didn't know about this good news, because just the night before the atomic bomb was dropped, the old president suddenly became cerebral congestion and fell into a coma. After urgent discussions, Congress appointed Vice President Truman as the acting president. It has to be said that this is a regret.

Just when Hiroshima was planted with mushrooms, in addition to the US fighter jets, there were several specially modified Lille-2 transport aircraft that had just arrived from Vladivostok to watch.

The special surveying and mapping forces of the Soviet Red Army watched the nuclear explosion throughout the whole process and recorded all the relevant data of the little boy. Just when the Americans were excited, the Soviet nuclear experts quickly received the relevant data.

After rigorous analysis, the experts came to a roughly reliable conclusion: this is a uranium bomb with an explosion power of about 15,000 tons. The power can only be said to be careless. If you can figure out how much uranium 5 the little boy used, you can roughly estimate the level of the American atomic bomb. The latter point was soon understood. When the little boy learned that the little boy consumed 64 kilograms of uranium 5, the Soviet experts curled their lips and were very disdainful. Because this data is too embarrassing, 64 kilograms of uranium 5 of the explosion equivalent of more than 10,000 tons is required to use 64 kilograms of uranium, which is an absolute waste. It can even be said that most of the uranium materials in this atomic bomb were wasted. At the current level of the Soviet Union, creating an atomic bomb with an explosion power of about 20,000 tons only requires five kilograms of uranium 5. The gap between the two sides is obvious.

These things now make the Political Bureau and the Military Commission a little relieved, which fully demonstrates that the Soviet Union's related technology is still far ahead of the Americans. As long as the investment continues to be guaranteed, it will be difficult for Americans to catch up.

Of course, these are not known to the Americans, so after successfully planting mushrooms for Hiroshima, the United States ******* quickly announced this great news to the whole world: "The nuclear strike on Hiroshima is the victory of peace and justice-loving humans against the devil, which means that the free and peaceful world has mastered the ultimate ability. All resistance from Japan is meaningless. We advise the Japanese government to put down its weapons unconditionally and surrender immediately. This is your only way out!"

Especially after the photos of the nuclear explosion came out, when the whole world was shocked by the "America's achievements", the Americans' pride was vividly expressed. Soon this emotion turned into various political pressures, and the Soviet Union was naturally under pressure. On that day, the US Secretary of State and the US ambassador to the Soviet Union made more than once public speeches or issued obvious warnings, "hope" the Soviet Union did not make meaningless resistance and no longer provoked the US patience.

On this day, the free and democratic world was excited and fell into a carnival. Churchill showed off his victory with his iconic cigar in his mouth. Learwin also breathed a sigh of relief for the first time, thinking he won. While they were excited, a military train with the highest level of defense quietly drove into the downtown area of ​​Vladivostok. Under the strict escort of kgb security personnel, several highly confidential containers on the special train were carefully unloaded and properly kept in the kgb warehouse.

At the same time, a Type 41 destroyer that had just received a special modification not long ago leaned on the dock in Vladivostok. The original two torpedo devices in the middle of the destroyer were completely cancelled, and the chimney in the middle was redirected, leaving a large area of ​​"empty space". At this time, a large missile launcher was installed on this "empty space". This launcher specially prepared for nuclear cruise missiles is enough to accommodate hundreds of tons of T2 missiles. According to the arrangements of the Military Commission, the next nuclear strike against Japan will be used to obtain such missiles.

Of course, there is a debate within the Political Bureau on whether to use a strategic bomber or a T2 missile for the first time to use nuclear weapons. The mainstream opinion is to be on the safe side. It is better to use a traditional bomber when throwing the first mushroom. After all, the T2 is not very safe and unreliable.

So soon, another ten specially modified Tu-3 bombers also flew to Vladivostok. The reason why so many of them were modified was actually for insurance. In the end, the unit with the best aircraft in the aircraft was in the best condition and the best flight technology would be used during the bombing.

To be honest, these cross Tu-3s were also the only crew that the Soviet Union could use for nuclear strikes at that time. Not only the aircraft had been specially transformed and some radiation protection devices were equipped, but the crew members had only carried out one task in the past year, that is, endless simulated bomb drop training. Let’s talk about these crew members, almost every one of them had at least won the Lenin Medal and was a hero who had performed countless bombing missions in the war for the country. Moreover, each pilot had undergone countless political reviews and inspections, and only the most reliable pilots could receive this honor.

Yes, in the Soviet Union's view, planting mushrooms for Japan was an honor, and only the best pilots could get this honor. Just as the entire free world was in a carnival, the Tu-3 bomber carrying the atomic bomb flew into the sky in the dark.

About three hours later, the plane arrived over Tokyo, at 6 a.m. The entire Tokyo was still in a sleepy period before dawn. The Japanese did not know that they were going to hell in their sleep.

The first atomic bomb used in actual combat in the Soviet Union was dropped, and turned into a dazzling fireball at a height of about 50 meters. With a thunder, Tokyo, which had been damaged by the strategic bombing of the US military, finally completed its last journey.

According to the measurements of Soviet Air Force mapping machines, the explosion of this atomic bomb was about 30,000 tons. The violent explosion caused 100,000 deaths in just one minute. A large number of buildings, including the imperial palace of the Japanese Emperor, were destroyed, and the entire Tokyo turned into hell on earth.

In addition to the Soviet Air Force, the first batch of people who observed this explosion also noticed the explosion at the first time. A large number of American bomber pilots who returned to the night bombing mission said that a second sun appeared in Tokyo, and the violent explosion could be heard two hundred kilometers away.

The explosion immediately attracted the attention of the US Pacific Theater Command. After learning the news, it immediately sent a reconnaissance plane to investigate.

Of course, the Americans did not fully realize what had happened at this time. There were even many optimistic Yankees who thought that this was their second nuclear strike against Japan and were all laughing at the joke. Only the generals of the Pacific Theater Command knew that the United States did have plans to launch a second nuclear strike against Japan, but it did not implement it. This big explosion was not their work.

Truman, who was sleeping, was woken up immediately. Nimitz and MacArthur sent him an urgent telegram at the same time, claiming that Tokyo was suspected to have been attacked by an atomic bomb.

Truman, who had just become president, was still immersed in happiness and thought that he would have made progress in the past. So when he learned the news, he was shocked because now he has the ability to launch a nuclear strike against Japan, theoretically they should be the only ones who are capable of launching a nuclear strike, but Roosevelt knew very well that he had not ordered a second nuclear strike. So what was the suspected nuclear explosion? Who did it?

In fact, there are not many suspects at all. The most suspicious are the Soviet Union and Britain. Only these two countries have such strength, especially the Soviet Union, which deserves high suspicion. But Truman really doesn't want to believe that the Soviet Union also has nuclear weapons, because once this is confirmed, their carnival yesterday became a complete international joke. As for demonstrations and threats, it is even more ridiculous.

"I'll notify me if I have the specific result!"

Years of experience in political struggles have told Truman that he must be more cautious at this time. It is best not to express anything before he cannot be sure of the result, as it will only make him passive.

Truman sat blankly behind the desk, looking at various documents, but anyone familiar with the president knew how absent-minded he was at this time. Have you taken down the documents without seeing them?

After a few hours, about the morning of Moscow time, Secretary of State Stadnius hurried into the White House and said to Truman in a panic: "Mr. President, the news I just received. TASS is announcing to the world that they have launched a nuclear strike against Tokyo, Japan!"

With a click, Truman broke the pencil in his hand, which showed how surprised he was by the news. Although he still had one in ten thousand hoped that the Russians would be lying, the common sense of international politics told him that this was impossible.

Steidinius later recalled: "The president was stunned for a long time, but in fact we were all shocked by the news. The Soviet nuclear weapons came too suddenly, making us unprepared. Yesterday we were still celebrating that only the United States mastered the ultimate power that only God could possess. But when we woke up, we found that God had two... However, after the president was silent, he issued a series of orders, asking Nimitz to immediately determine the nature of the explosion and order Donovan to strengthen his intelligence work to see if he could find any clues. In the end, he prayed silently, hoping that God would bless the United States."

Churchill won't say much about his reaction. Learwin sighed again. In fact, as early as when the Americans succeeded, she had doubts. With her understanding of someone, someone would definitely attach great importance to the major issues of nuclear weapons, and the result of high attention is naturally impossible to master such weapons later than the Americans. She felt that it was impossible to know that the Soviet Union did not lie without any confirmation. The current situation is really unfavorable to the British Empire!

The two giants of the three giants already have atomic bombs, which makes the UK so pitiful. It can even be said that there are no giants now, only two giants.

Learvin wrote in his work diary at the time: "The world has opened a two-pole mode."

In fact, Lilwin's narrative is not completely correct. The correct statement is that the world has completely entered the bipolar mode. Because in the next competition for throwing a bomb, Britain was thrown farther and farther. After Nagasaki got an atomic bomb, the Soviet Union immediately threw the second one, followed by the third and fourth ones. Six Japanese cities turned into ashes in an instant. Even the most conservative estimate is that in less than a week, 500,000 Japanese people were killed. In the long run, at least one million Japanese people would die due to the atomic bomb, and the injured or the most disabled were as high as three million. What's even more terrible is that this nuclear competition did not come to an end, and the Soviet Union had to carry out the fifth nuclear strike.

The significance of this nuclear strike is very special, because in this nuclear strike, the Soviet Union used not an ordinary nuclear bomb, but an enhanced atomic bomb. What is the enhanced atomic bomb?

The "nuclear bomb" we are talking about today generally refers to two types, one is atomic bomb that reacts fission, and the other is a hydrogen bomb that reacts fusion (neutron bombs are relatively special hydrogen bombs). Hydrogen bombs also refer to "thermal nuclear weapons", or "multi-level thermonuclear weapons".

The beginning of hydrogen bomb development can be traced back to 1950. Truman asked American scientists to develop a "class bomb" against the first atomic bomb that exploded in 1949, and used fusion energy to use it. But as the fusion reaction mentioned earlier was not what the junior high school physics class said: an atomic bomb plus a tube of liquid tritium or deuterium would be OK. That configuration has no meaning.

So the Americans understood the "Taylor-Ulam" configuration and "two-level nuclear weapons", which are the "hydrogen bombs" in our general concept. This kind of bomb is divided into "primary" and "secondary". Using the rays exploded from the primary can trigger its fusion reaction before the "secondary" is blown away.

Today, the practical strategic nuclear weapons equipped by the five major rogues, that is, the so-called hydrogen bombs that are agreed to be mature usually do not have this two-level model, but use a "three-phase bomb" structure. The entire explosion process is a triple interaction between fission-fusion-fission. The three-phase bombs also have "primary" and "secondary", and there will be complex interactions between the two. In addition, there is a "shell layer", which is generally composed of uranium 8, which can ensure the subtle cooling of the secondary after the primary explosion; then it can generate nuclear fission reactions under the action of a large number of neutrons produced by the hydrogen bomb, and release energy. In fact, the fission generated by this layer of uranium-8 is the main source of energy for the strategic nuclear weapons of the five nuclear powers today. Because it is difficult to prepare as a fission material, highly enriched uranium 5 and fusion materials deuterium or tritium, uranium 8 are more common in nature. And various effect bombs (such as neutron bombs) can be produced through the adjustment of shell materials.

It is said that in theory, the "levels" can be further increased to create grade nuclear bombs. For example, the United States once designed the concept of a "level seven" nuclear bomb, and its explosion equivalent will be farther than the third-level Soviet "Tsar" bomb, whose explosion equivalent can reach 5,000 to 100 million tons. However, such an exaggerated nuclear bomb has no practical value, so it has not entered the actual manufacturing stage.

The "enhanced atomic bomb" is a "by-product" of the science and technology tree that has been pointed out in the process of studying hydrogen bombs. It is considered an unsuccessful attempt before manufacturing hydrogen bombs. Fortunately, both the primary and secondary hydrogen bombs can actually be regarded as "enhanced atomic bombs" with special structures. It is not particularly failed to do it, and it is regarded as accumulating experience.

The so-called "enhanced atomic bomb" is simply to use the high temperature and pressure of the atomic bomb explosion to make the tritium-deuterium mixture placed in its core fusion reaction. They will turn into helium and release a large number of neutrons. The neutrons released in the fusion reaction can greatly accelerate the fission reaction process of the fission material wrapped outside them, allowing them to add fission reaction before being blown out, that is, they are wasted. Simply put, "enhanced atomic bomb" can enhance the utilization rate of fission materials and double the power of the atomic bomb.

Compared with the "multi-level nuclear weapons" commonly known as hydrogen bombs, the "enhanced atomic bomb" is still a "first-level nuclear weapon" and its structure is relatively simple. It also has certain significance for the miniaturization of atomic bombs. For example, replacing the uranium-8 reflective layer wrapped in the outer layer of the enhanced atomic bomb with beryllium can greatly reduce the diameter and weight without affecting the equivalent. In this way, the explosives required to compress the inner core can be reduced, thereby further reducing the overall mass of the bomb. On the other hand, by increasing or deuterium and tritium in the bomb core, the equivalent of the explosion can be controlled.

In short, the power of an enhanced atomic bomb is not as strong as that of a hydrogen bomb. It is an attempt to innovate technological innovation. Big wave SS at the level of the five major rogues have had the idea of ​​using an enhanced atomic bomb, but some major rogues have continuously tested and found that the path was wrong, and the explosion power was limited, thus embarking on the path of "three-phase bomb". Other major rogues have found that an enhanced atomic bomb was useless in the theoretical research stage, and they directly opened their brains to create the correct model of the "three-phase bomb" or hydrogen bomb.

Of course, these are all later stories, because the Americans had just completed the atomic bomb at this time, and they were still a little short of the hydrogen bomb. The Soviet Union's first choice between "enhanced atomic bomb" or "hydrogen bomb". Because of Li Xiaofeng's intervention, the Soviet Union greatly accelerated the progress of new nuclear weapons, and the focus of the key is naturally the use of tritium and deuterium.

We later generations naturally know the significance of tritium and deuterium to fusion reaction, but not everyone had tritium and deuterium at that time, and everyone could research hydrogen bombs. In all articles about thermonuclear weapons, you will tell you that tritium and deuterium are a key material. However, on Earth, the isotopes of the two hydrogens, deuterium and tritium, are extremely rare. If you want to use them to make nuclear bombs, you have to find a way to manually produce this substance.

At present, there are two most common methods. One is to use alloys or ceramics with high lithium-6 enrichment to make targets and put them in the reactor for irradiation to produce tritium. Another method is to extract tritium from heavy water irradiated with neutrons in the reactor.

But no matter which method it is, the production efficiency is pitifully low. So even if a certain immortal makes a cheat or in principle makes a cheat for the Soviet Union, without tritium, he can't create hydrogen bombs and enhanced atomic bombs.

In March 1945, after working for several years, the Soviet Union produced enough tritium. Because the configuration of the hydrogen bomb was not completely accurate, the relevant data models were still intensively calculated using computers. Therefore, the Soviet Union could only conduct an enhanced atomic bomb test first to touch the bottom.

If the enhanced atomic bomb can meet the needs, there is no need to engage in hydrogen bombs. Otherwise, hydrogen bomb projects will get the highest priority.

Li Xiaofeng is unquestionable about this. Sometimes failure is more precious than success. If you don’t fail, you won’t know that you have taken the wrong path. It is not a bad thing to let those guys who support the enhancement atomic bomb see the actual results... (To be continued.)8
