If someone asks which country made the first atomic bomb? This seems to be an idiotic question, and the answer is known even to schoolchildren around the world - the United States. Pen ~ fun ~ pavilion www.biquge.info

But if the person asked was a nuclear weapons expert from the world's major powers, he might have received a completely different answer - the Soviet Union.

In September 1943, the Soviet Union completed preparations for the explosion of the first nuclear device, which had a yield of only about 2,000 tons, but was the world's first real atomic bomb (although it was not yet operationally capable).

On September 10, the atomic bomb was planted on an uninhabited island in the middle of the lake, and a large number of Soviet officials and scientists, led by Malenkov, went to the scene to watch the first-ever nuclear explosion. Before the detonation, people were evacuated to underground bunkers 1 kilometre away, and only the physicist Petersak refused to enter the bunker - he did not believe that the atomic bomb would be so powerful.

The atomic bomb was a success, it raised the first mushroom-shaped ball of smoke formed by a nuclear explosion on Earth, and Bertelsak was fortunate enough to be the first to see the atomic bomb explode, but he could not tell anyone what he saw - he was blown up without a trace!

On July 21, Lin Jun was on a long-distance plane thinking about the memories above. He hasn't figured out how fast Stalin really said that "research is fast there"? The experimental graphite reactor had been in operation since the end of the previous year, which Lin Jun knew, but did not know much about other things.

Secrecy is one reason, as is lack of energy. Although he has the right to know the top secret, after the Novosibirsk project officially started, it was Vorosinov who was in charge, and the specific person responsible was Georgy Maksimilianovich Malenkov, and Lin Jun did not point fingers.

Although this Malenkov is political, he does not pose a threat to Lin Jun, he is very efficient, and he is still an all-rounder who knows engineering, so it is appropriate for him to be in charge.

"It's not possible for Butuc to make a practical explosive device yet, so what progress is there?" Leaning back in the seat, my mind was a little messy.

On the other side of the cabin, Gussev and Leonov were still talking about the shocking scene they had seen yesterday, and Alyosha and Landeskozy were closing their eyes and recuperating, and the sound of two staff officers talking in their ears came from them.

What I saw yesterday was a shock to my attaché and to Polikarpov: when a DP-1 turbojet engine was started on a test bench, the deafening roar stifled everyone's nerves.

The engineers of the institute were so red that the comrades of the aircraft designers shouted to the people next to them (if you don't shout, you can't hear them): "I want to build the best plane out of it!" It's what I want! ”

Lin Jun's attaché was fortunate enough to see this shocking scene, in Alyosha's words: "The whole earth is trembling, a hundred times more violent than the cold wind of Siberia!" ”

Lin Jun didn't show anything special, but for a moment he returned to the airport in his previous life in a trance, and the deafening roar seemed to connect two different worlds. His unusual performance impressed everyone again: Comrade Marshal is just different, he can remain calm in the face of any situation!

Others don't have to worry if Lin Jun doesn't like this new engine, because this is the research he himself supports, and it seems that he has long been able to foresee everything he sees today.

There is one aspect of DP-1 technology that he is very dissatisfied with, but there is nothing he can do about it at the moment, and he can only wait for the level of manufacturing process and the quality of raw materials to improve: after 50 hours of use, the first time will need to be renovated, and the first time will be the last.

The consistent position of the Soviet military industry is that it works, and there is nothing wrong with this, but Lin Jun hopes that the jet engine can at least reach the average life of the piston engine in the future, otherwise the indicator of 50 hours is simply a disaster for logistics, and how can it get 200 hours!

But now it's the experimental stage, and 50 hours is okay, and people can't stand on this mountain and see that mountain is high, and still know that they are satisfied.

For the time being, Polikarpov stayed at the research base to carry out preliminary preparations. The armament department has already received instructions from Lin Jun to facilitate the work of aircraft designers, the old team of the Central Aircraft Design Bureau Polikarpov will become the backbone of the aircraft design group, and the Air Force will give him the most experienced test pilots.

In the evening, two Ry-2s arrived at a heavily guarded military airfield on the outskirts of Novosibirsk.

Lin Jun was greeted by officers who were basically officers of the Ministry of Internal Affairs, and only one person was dressed as a civilian—a thirty-seven-eight-year-old beard.

"Hello, Comrade Marshal, I am Igor Vasilyevich Kurchatov, Director of the Second Institute of the Institute. Welcome to Novosibirsk, today there is a rather important experiment, from which Comrade Bettuko will not be able to get out. ”

The face in front of Lin Jun was not very good, this was obviously a side effect of overwork. Lin Jun didn't blame his old friend for not coming, he knew that some physical experiments couldn't be stopped all at once.

"Hello, Comrade Kurchatov. This time I have come to interfere with your work, and if my work causes you any inconvenience, you can tell me that you are my leader here. ”

Lin Jun is very modest, not only because his sudden arrival may cause problems for experts, but also because he respects the person in front of him: he was the one who developed the first atomic bomb for the Soviet Union and the communist camp in history, and he was also the one who later tried to dissuade the country from continuing to develop nuclear weapons - Igor Vasilyevich Kurchatov, the father of the Soviet atomic bomb!

Three-time winner of the title of "Hero of Socialist Labor"! Physicist, academician of the USSR Academy of Social Sciences, winner of four USSR State Prizes and one Lenin Prize, five Lenin Medals, two Red Banner Orders and several medals during his lifetime, deputy of the 3rd-5th Supreme Soviet of the USSR. After his death, he was buried under the walls of the Kremlin. There is a small city and a nuclear power plant named after him, the USSR Academy of Sciences has the Kurchatov Medal, and Mendeleev is named after the 104th element of the periodic table. In the last years of his life, he contributed to the peaceful use of nuclear energy, and in his last public speech, he warned people: "The use of atomic and hydrogen bombs will lead to catastrophe!" Of course, such a person can gain Lin Jun's respect!

The life of this man in front of him is a living legend, Vladimir Ilyich Ulyanov (Lenin) is his old alumnus, the future "father of the atomic bomb" was a naughty boy who was tired of the classroom, and his grades in secondary school were "manners" were not passed, and all other subjects were excellent.

When the civil war broke out, everyone else went to volunteer, but he was admitted to university to continue his studies. In 1923, students often passed out in cold classrooms. In order not to go to school barefoot, the future academician of the Academy of Sciences sewed shoes for himself from horseskin. In order to earn money to buy food rations, he worked as a lumberjack, a janitor, and a tutor in an orphanage----

He was at a loss as to what kind of job to choose after graduation, so he enrolled in the shipbuilding department of the Petrograd (which had not yet been renamed) Polytechnic Institute. At this time, physics had become his passion, and after graduating he went to Baku Polytechnic Institute for a year to study semiconductors. In 1925, at the age of 22, Igor received an invitation to work at the Leningrad Institute of Physics and Technology.

In 1932, the German physicist Heisenberg revealed the principle that the nucleus of an atom is composed of protons and neutrons. In 1938, German scientist Otto Hahn and his assistant Strassmann further discovered on the basis of the experiments of French scientist Marie Joliot-Curie: when neutrons hit the uranium nucleus, one axis nucleus absorbed one neutron and split into two lighter nuclei, losing mass in the process, thus releasing huge energy.

This is the world-famous nuclear fission reaction. In 1934, the Soviet physicist Kurchatov built an atomic accelerator from scratch in his own research institute. This test gave an important impetus to the construction of the first cyclotron in the Soviet Union.

At a regular meeting of the Academy of Sciences in 1936, Kurchatov was inexplicably slammed: Soviet nuclear physicists should have been commended for their impressive work in a short period of time, while officials accused them of squandering state funds on "meaningless" nuclear physics. Kurchatov, who was in a precarious situation, was fortunate to be sheltered by the academic authority Wai Fei, and he and his colleagues were spared.

After that, Kurchatov's life began to take a major turn, and he received an order from the Kremlin to take all the research equipment and materials with him, and as soon as he arrived with all his assistants, he was accompanied by Betuthuko.

Kurchatov's legend lies not only in scientific research, but also in his foresight: the Great Patriotic War of the Soviet Union began in June 1941. The Central Committee asked scientists to concentrate all their interest on the research of the equipment needed to defeat the German fascists, and Kurchatov had to put nuclear research on hold for the time being and began to study the demagnetization of the ships of the Black Sea Fleet.

In the spring of 1942, the Soviet physicist Felurov discovered that academic articles on nuclear energy research had disappeared from scientific and technical magazines in the United States, Britain and Germany. Kurchatov is keenly aware that those countries are secretly developing nuclear weapons.

In the autumn of that year, Soviet intelligence received accurate information that nuclear weapons research had been carried out in Germany.

The intelligence was reported to Stalin, and soon the leading physicists were summoned to the Kremlin. Academicians of the Academy of Sciences, Peter Kapitsa and Joffey, are optimistic: although the USSR did not have even the basic conditions (both technical and theoretical), it is unlikely that Germany will have an atomic bomb in the near future.

However, Kurchatov predicted that within a few years virtue would develop an atomic bomb.

Molotov, who was then the head of the political side of the atomic bomb development committee, asked him bluntly: "So can you build an atomic bomb?" ”

"Yes," replied the 39-year-old scientist confidently, "but it takes manpower and time, and it's useless to be in a hurry." ”

Kurchatov is a legend, a legend that broke the nuclear monopoly of the imperialist countries! Without him, the communist camp would most likely be at a disadvantage for many more years in the confrontation with the capitalist bloc.
