The first atomic bomb in the world. H-bomb

American Robert Oppenheimer and Soviet scientist Igor Kurchatov are officially recognized as the fathers of the atomic bomb. But in parallel, deadly weapons were developed in other countries (Italy, Denmark, Hungary), so the discovery rightfully belongs to everyone.

The German physicists Fritz Strassmann and Otto Hahn were the first to tackle this issue, who in December 1938 for the first time managed to artificially split the atomic nucleus of uranium. And six months later, at the Kummersdorf test site near Berlin, the first reactor was already being built and urgently purchased uranium ore from the Congo.

"Uranium project" - the Germans start and lose

In September 1939, the Uranium Project was classified. 22 reputable scientific centers were attracted to participate in the program, the research was supervised by the Minister of Armaments Albert Speer. The construction of an isotope separation plant and the production of uranium for extracting an isotope from it that supports a chain reaction was entrusted to the IG Farbenindustry concern.

For two years, a group of the venerable scientist Heisenberg studied the possibilities of creating a reactor with and heavy water. A potential explosive (the isotope uranium-235) could be isolated from uranium ore.

But for this, an inhibitor is needed that slows down the reaction - graphite or heavy water. The choice of the last option created an insurmountable problem.

The only plant for the production of heavy water, which was located in Norway, after the occupation was put out of action by local resistance fighters, and small stocks of valuable raw materials were taken to France.

The explosion of an experimental nuclear reactor in Leipzig also prevented the rapid implementation of the nuclear program.

Hitler supported the uranium project as long as he hoped to obtain a super-powerful weapon that could influence the outcome of the war he unleashed. After the cuts in public funding, the programs of work continued for some time.

In 1944, Heisenberg managed to create cast uranium plates, and a special bunker was built for the reactor plant in Berlin.

It was planned to complete the experiment to achieve a chain reaction in January 1945, but a month later the equipment was urgently transported to the Swiss border, where it was deployed only a month later. In a nuclear reactor there were 664 cubes of uranium weighing 1525 kg. It was surrounded by a graphite neutron reflector weighing 10 tons, an additional one and a half tons of heavy water was loaded into the core.

On March 23, the reactor finally started working, but the report to Berlin was premature: the reactor did not reach a critical point, and a chain reaction did not occur. Additional calculations have shown that the mass of uranium must be increased by at least 750 kg, proportionally adding the amount of heavy water.

But the reserves of strategic raw materials were at the limit, as was the fate of the Third Reich. On April 23, the Americans entered the village of Haigerloch, where the tests were carried out. The military dismantled the reactor and transported it to the United States.

The first atomic bombs in the USA

A little later, the Germans took up the development of the atomic bomb in the United States and Great Britain. It all started with a letter from Albert Einstein and his co-authors, immigrant physicists, sent by them in September 1939 to US President Franklin Roosevelt.

The appeal stressed that Nazi Germany was close to building an atomic bomb.

Stalin first learned about the work on nuclear weapons (both allies and opponents) from intelligence officers in 1943. They immediately decided to create a similar project in the USSR. The instructions were issued not only to scientists, but also to intelligence, for which the extraction of any information about nuclear secrets has become a super task.

The invaluable information about the developments of American scientists, which Soviet intelligence officers managed to obtain, significantly advanced the domestic nuclear project. It helped our scientists avoid inefficient search paths and significantly speed up the implementation of the final goal.

Serov Ivan Alexandrovich - head of the operation to create a bomb

Of course, the Soviet government could not ignore the successes of German nuclear physicists. After the war, a group of Soviet physicists was sent to Germany - future academicians in the form of colonels of the Soviet army.

Ivan Serov, the first deputy commissar of internal affairs, was appointed head of the operation, which allowed scientists to open any doors.

In addition to their German colleagues, they found reserves of uranium metal. This, according to Kurchatov, reduced the development time of the Soviet bomb by at least a year. More than one ton of uranium and leading nuclear specialists were also taken out of Germany by the American military.

Not only chemists and physicists were sent to the USSR, but also skilled labor - mechanics, electricians, glass blowers. Some employees were found in POW camps. In total, about 1,000 German specialists worked on the Soviet nuclear project.

German scientists and laboratories on the territory of the USSR in the postwar years

A uranium centrifuge and other equipment were transported from Berlin, as well as documents and reagents from the von Ardenne laboratory and the Kaiser Institute of Physics. As part of the program, laboratories "A", "B", "C", "D" were created, which were headed by German scientists.

The head of laboratory "A" was Baron Manfred von Ardenne, who developed a method for gaseous diffusion purification and separation of uranium isotopes in a centrifuge.

For the creation of such a centrifuge (only on an industrial scale) in 1947, he received the Stalin Prize. At that time, the laboratory was located in Moscow, on the site of the famous Kurchatov Institute. The team of each German scientist included 5-6 Soviet specialists.

Later, laboratory "A" was taken to Sukhumi, where a physico-technical institute was created on its basis. In 1953, Baron von Ardenne became a Stalin laureate for the second time.

Laboratory "B", which conducted experiments in the field of radiation chemistry in the Urals, was headed by Nikolaus Riehl - a key figure in the project. There, in Snezhinsk, the talented Russian geneticist Timofeev-Resovsky worked with him, with whom they were friends back in Germany. The successful test of the atomic bomb brought Riel the star of the Hero of Socialist Labor and the Stalin Prize.

The research of laboratory "B" in Obninsk was led by Professor Rudolf Pose, a pioneer in the field of nuclear testing. His team managed to create fast neutron reactors, the first nuclear power plant in the USSR, and designs for reactors for submarines.

On the basis of the laboratory, the A.I. Leipunsky. Until 1957, the professor worked in Sukhumi, then in Dubna, at the Joint Institute for Nuclear Technologies.

Laboratory "G", located in the Sukhumi sanatorium "Agudzery", was headed by Gustav Hertz. The nephew of the famous 19th-century scientist gained fame after a series of experiments that confirmed the ideas of quantum mechanics and the theory of Niels Bohr.

The results of his productive work in Sukhumi were used to create an industrial plant in Novouralsk, where in 1949 they made the filling of the first Soviet bomb RDS-1.

The uranium bomb that the Americans dropped on Hiroshima was a cannon-type bomb. When creating the RDS-1, domestic nuclear physicists were guided by the Fat Boy, the “Nagasaki bomb”, made from plutonium according to the implosive principle.

In 1951, Hertz was awarded the Stalin Prize for his fruitful work.

German engineers and scientists lived in comfortable houses, they brought their families, furniture, paintings from Germany, they were provided with a decent salary and special food. Did they have the status of prisoners? According to academician A.P. Alexandrov, an active participant in the project, they were all prisoners in such conditions.

Having received permission to return to their homeland, the German specialists signed a non-disclosure agreement about their participation in the Soviet atomic project for 25 years. In the GDR, they continued to work in their specialty. Baron von Ardenne was twice a laureate of the German National Prize.

The professor headed the Physics Institute in Dresden, which was created under the auspices of the Scientific Council for the Peaceful Applications of Atomic Energy. The Scientific Council was headed by Gustav Hertz, who received the National Prize of the GDR for his three-volume textbook on atomic physics. Here, in Dresden, at the Technical University, Professor Rudolf Pose also worked.

The participation of German specialists in the Soviet atomic project, as well as the achievements of Soviet intelligence, do not diminish the merits of Soviet scientists, who, with their heroic labor, created domestic atomic weapons. And yet, without the contribution of each participant in the project, the creation of the atomic industry and the nuclear bomb would have dragged on for indefinite

The one who invented the atomic bomb could not even imagine what tragic consequences this miracle invention of the 20th century could lead to. Before this superweapon was experienced by the inhabitants of the Japanese cities of Hiroshima and Nagasaki, a very long way had been done.

A start

In April 1903, the famous French physicist Paul Langevin gathered his friends in the Paris Garden. The reason was the defense of the dissertation of the young and talented scientist Marie Curie. Among the distinguished guests was the famous English physicist Sir Ernest Rutherford. In the midst of the fun, the lights were put out. Marie Curie announced to everyone that there would now be a surprise.

With a solemn air, Pierre Curie brought in a small tube of radium salts, which shone with a green light, causing extraordinary delight among those present. In the future, the guests heatedly discussed the future of this phenomenon. Everyone agreed that thanks to radium, the acute problem of lack of energy would be solved. This inspired everyone to new research and further perspectives.

If they had been told then that laboratory work with radioactive elements would lay the foundation for a terrible weapon of the 20th century, it is not known what their reaction would have been. It was then that the story of the atomic bomb began, which claimed the lives of hundreds of thousands of Japanese civilians.

Game ahead of the curve

On December 17, 1938, the German scientist Otto Gann obtained irrefutable evidence of the decay of uranium into smaller elementary particles. In fact, he managed to split the atom. In the scientific world, this was regarded as a new milestone in the history of mankind. Otto Gunn did not share the political views of the Third Reich.

Therefore, in the same year, 1938, the scientist was forced to move to Stockholm, where, together with Friedrich Strassmann, he continued his scientific research. Fearing that fascist Germany will be the first to receive a terrible weapon, he writes a letter to the President of America with a warning about this.

The news of a possible lead greatly alarmed the US government. The Americans began to act quickly and decisively.

Who created the atomic bomb? American project

Even before the outbreak of World War II, a group of American scientists, many of whom were refugees from the Nazi regime in Europe, were tasked with developing nuclear weapons. The initial research, it is worth noting, was carried out in Nazi Germany. In 1940, the government of the United States of America began funding its own program to develop atomic weapons. An incredible amount of two and a half billion dollars was allocated for the implementation of the project.

Outstanding physicists of the 20th century were invited to carry out this secret project, including more than ten Nobel laureates. In total, about 130 thousand employees were involved, among whom were not only the military, but also civilians. The development team was led by Colonel Leslie Richard Groves, with Robert Oppenheimer as supervisor. He is the man who invented the atomic bomb.

A special secret engineering building was built in the Manhattan area, which is known to us under the code name "Manhattan Project". Over the next few years, the scientists of the secret project worked on the problem of nuclear fission of uranium and plutonium.

Non-peaceful atom by Igor Kurchatov

Today, every schoolchild will be able to answer the question of who invented the atomic bomb in the Soviet Union. And then, in the early 30s of the last century, no one knew this.

In 1932, Academician Igor Vasilyevich Kurchatov was one of the first in the world to start studying the atomic nucleus. Gathering like-minded people around him, Igor Vasilievich in 1937 created the first cyclotron in Europe. In the same year, he and his like-minded people create the first artificial nuclei.

In 1939, I. V. Kurchatov began to study a new direction - nuclear physics. After several laboratory successes in studying this phenomenon, the scientist gets at his disposal a secret research center, which was named "Laboratory No. 2". Today, this secret object is called "Arzamas-16".

The target direction of this center was a serious research and development of nuclear weapons. Now it becomes obvious who created the atomic bomb in the Soviet Union. There were only ten people on his team then.

atomic bomb to be

By the end of 1945, Igor Vasilyevich Kurchatov managed to assemble a serious team of scientists numbering more than a hundred people. The best minds of various scientific specializations came to the laboratory from all over the country to create atomic weapons. After the Americans dropped the atomic bomb on Hiroshima, Soviet scientists realized that this could also be done with the Soviet Union. "Laboratory No. 2" receives a sharp increase in funding from the country's leadership and a large influx of qualified personnel. Lavrenty Pavlovich Beria is appointed responsible for such an important project. The enormous labors of Soviet scientists have borne fruit.

Semipalatinsk test site

The atomic bomb in the USSR was first tested at the test site in Semipalatinsk (Kazakhstan). On August 29, 1949, a 22 kiloton nuclear device shook the Kazakh land. Nobel laureate physicist Otto Hanz said: “This is good news. If Russia has atomic weapons, then there will be no war.” It was this atomic bomb in the USSR, encrypted as product number 501, or RDS-1, that eliminated the US monopoly on nuclear weapons.

Atomic bomb. Year 1945

Early in the morning of July 16, the Manhattan Project conducted its first successful test of an atomic device - a plutonium bomb - at the Alamogordo Test Site, New Mexico, USA.

The money invested in the project was well spent. The first atomic explosion in the history of mankind was carried out at 5:30 in the morning.

“We have done the work of the devil,” said later Robert Oppenheimer, the one who invented the atomic bomb in the United States, later called the “father of the atomic bomb.”

Japan does not capitulate

By the time of the final and successful testing of the atomic bomb, Soviet troops and allies had finally defeated Nazi Germany. However, there was one state that promised to fight to the end for dominance in the Pacific Ocean. From mid-April to mid-July 1945, the Japanese army repeatedly carried out air strikes against allied forces, thereby inflicting heavy losses on the US army. At the end of July 1945, the militarist government of Japan rejected the Allied demand for surrender in accordance with the Potsdam Declaration. In it, in particular, it was said that in case of disobedience, the Japanese army would face rapid and complete destruction.

President agrees

The American government kept its word and began targeted bombing of Japanese military positions. Air strikes did not bring the desired result, and US President Harry Truman decides on the invasion of American troops into Japan. However, the military command dissuades its president from such a decision, citing the fact that the American invasion will entail a large number of victims.

At the suggestion of Henry Lewis Stimson and Dwight David Eisenhower, it was decided to use a more effective way to end the war. A big supporter of the atomic bomb, US Presidential Secretary James Francis Byrnes, believed that the bombing of Japanese territories would finally end the war and put the US in a dominant position, which would positively affect the future course of events in the post-war world. Thus, US President Harry Truman was convinced that this was the only correct option.

Atomic bomb. Hiroshima

The first target was the small Japanese city of Hiroshima, with a population of just over 350,000, located five hundred miles from Japan's capital, Tokyo. After the modified Enola Gay B-29 bomber arrived at the US naval base on Tinian Island, an atomic bomb was installed on board the aircraft. Hiroshima was supposed to experience the effects of 9,000 pounds of uranium-235.
This hitherto unseen weapon was intended for civilians in a small Japanese town. The bomber commander was Colonel Paul Warfield Tibbets, Jr. The US atomic bomb bore the cynical name "Baby". On the morning of August 6, 1945, at about 8:15 am, the American "Baby" was dropped on the Japanese Hiroshima. About 15 thousand tons of TNT destroyed all life within a radius of five square miles. One hundred and forty thousand inhabitants of the city died in a matter of seconds. The surviving Japanese died a painful death from radiation sickness.

They were destroyed by the American atomic "Kid". However, the devastation of Hiroshima did not cause the immediate surrender of Japan, as everyone expected. Then it was decided to another bombardment of Japanese territory.

Nagasaki. Sky on fire

The American atomic bomb "Fat Man" was installed on board the B-29 aircraft on August 9, 1945, all in the same place, at the US naval base in Tinian. This time the aircraft commander was Major Charles Sweeney. Initially, the strategic target was the city of Kokura.

However, the weather conditions did not allow to carry out the plan, a lot of clouds interfered. Charles Sweeney went into the second round. At 11:02 am, the American nuclear-powered Fat Man swallowed up Nagasaki. It was a more powerful destructive air strike, which, in its strength, was several times higher than the bombing in Hiroshima. Nagasaki tested an atomic weapon weighing about 10,000 pounds and 22 kilotons of TNT.

The geographical location of the Japanese city reduced the expected effect. The thing is that the city is located in a narrow valley between the mountains. Therefore, the destruction of 2.6 square miles did not reveal the full potential of American weapons. The Nagasaki atomic bomb test is considered the failed "Manhattan Project".

Japan surrendered

On the afternoon of August 15, 1945, Emperor Hirohito announced his country's surrender in a radio address to the people of Japan. This news quickly spread around the world. In the United States of America, celebrations began on the occasion of the victory over Japan. The people rejoiced.
September 2, 1945 on board the American battleship "Missouri", anchored in Tokyo Bay, was signed a formal agreement to end the war. Thus ended the most brutal and bloody war in the history of mankind.

For six long years, the world community has been moving towards this significant date - since September 1, 1939, when the first shots of Nazi Germany were fired on the territory of Poland.

Peaceful atom

A total of 124 nuclear explosions were carried out in the Soviet Union. It is characteristic that all of them were carried out for the benefit of the national economy. Only three of them were accidents involving the release of radioactive elements.

Programs for the use of peaceful atom were implemented only in two countries - the United States and the Soviet Union. The peaceful nuclear power industry also knows an example of a global catastrophe, when on April 26, 1986, a reactor exploded at the fourth power unit of the Chernobyl nuclear power plant.

Who invented the nuclear bomb?

The Nazi Party has always recognized the importance of technology and has invested heavily in the development of rockets, aircraft and tanks. But the most outstanding and dangerous discovery was made in the field of nuclear physics. Germany was in the 1930s perhaps the leader in nuclear physics. However, with the rise of the Nazis, many German physicists who were Jews left the Third Reich. Some of them emigrated to the US, bringing with them disturbing news: Germany may be working on an atomic bomb. These news prompted the Pentagon to take action to develop its own nuclear program, which they called the "Manhattan Project" ...

An interesting, but more than dubious version of the "secret weapon of the Third Reich" was proposed by Hans Ulrich von Krantz. In his book The Secret Weapon of the Third Reich, a version is put forward that the atomic bomb was created in Germany and that the United States only imitated the results of the Manhattan Project. But let's talk about this in more detail.

Otto Hahn, the famous German physicist and radiochemist, together with another prominent scientist Fritz Straussmann, discovered the fission of the uranium nucleus in 1938, in fact, giving this start to work on the creation of nuclear weapons. In 1938, nuclear developments were not classified, but in almost no country, except Germany, they were not given due attention. They didn't see much point. British Prime Minister Neville Chamberlain said: "This abstract matter has nothing to do with public needs." Professor Gan assessed the state of nuclear research in the United States of America as follows: “If we talk about a country in which the processes of nuclear fission are given the least attention, then we should undoubtedly name the United States. Of course, now I am not considering Brazil or the Vatican. However, among the developed countries, even Italy and communist Russia are far ahead of the United States.” He also noted that little attention is paid to the problems of theoretical physics on the other side of the ocean, priority is given to applied developments that can give immediate profit. Hahn's verdict was unequivocal: "I can confidently say that over the next decade, North Americans will not be able to do anything significant for the development of atomic physics." This statement served as the basis for the construction of the von Krantz hypothesis. Let's take a look at his version.

At the same time, the Alsos group was created, whose activities were limited to "bounty hunting" and the search for the secrets of German atomic research. Here a natural question arises: why should Americans look for other people's secrets if their own project is in full swing? Why did they rely so much on other people's research?

In the spring of 1945, thanks to the activities of Alsos, many scientists who took part in German nuclear research fell into the hands of the Americans. By May, they had Heisenberg, and Hahn, and Osenberg, and Diebner, and many other outstanding German physicists. But the Alsos group continued active searches in the already defeated Germany - until the very end of May. And only when all the major scientists were sent to America, "Alsos" ceased its activities. And at the end of June, the Americans are testing the atomic bomb, allegedly for the first time in the world. And in early August, two bombs are dropped on Japanese cities. Hans Ulrich von Krantz drew attention to these coincidences.

The researcher also doubts that only a month has passed between testing and combat use of the new superweapon, because the manufacture of a nuclear bomb is impossible in such a short time! After Hiroshima and Nagasaki, the next US bombs did not enter service until 1947, preceded by additional tests at El Paso in 1946. This suggests that we are dealing with a carefully concealed truth, since it turns out that in 1945 the Americans drop three bombs - and all are successful. The next tests - the same bombs - take place a year and a half later, and not too successfully (three out of four bombs did not explode). Serial production began another six months later, and it is not known to what extent the atomic bombs that appeared in the American army warehouses corresponded to their terrible purpose. This led the researcher to the idea that “the first three atomic bombs - the very ones of the forty-fifth year - were not built by the Americans on their own, but received from someone. To put it bluntly - from the Germans. Indirectly, this hypothesis is confirmed by the reaction of German scientists to the bombing of Japanese cities, which we know about thanks to the book by David Irving. According to the researcher, the atomic project of the Third Reich was controlled by the Ahnenerbe, which was personally subordinate to the SS leader Heinrich Himmler. According to Hans Ulrich von Krantz, "the nuclear charge is the best tool for post-war genocide, both Hitler and Himmler believed." According to the researcher, on March 3, 1944, the atomic bomb (Loki object) was delivered to the test site - in the swampy forests of Belarus. The tests were successful and aroused unprecedented enthusiasm in the leadership of the Third Reich. German propaganda had previously mentioned a “wonder weapon” of gigantic destructive power that the Wehrmacht would soon receive, now these motives sounded even louder. Usually they are considered a bluff, but can we unequivocally draw such a conclusion? As a rule, Nazi propaganda did not bluff, it only embellished reality. So far, it has not been possible to convict her of a major lie on the issues of the “wonder weapon”. Recall that propaganda promised jet fighters - the fastest in the world. And already at the end of 1944, hundreds of Messerschmitt-262s patrolled the airspace of the Reich. Propaganda promised rocket rain to the enemies, and from the autumn of that year, dozens of V-cruise rockets rained down on British cities every day. So why should the promised super-destructive weapon be considered a bluff?

In the spring of 1944, feverish preparations began for the mass production of nuclear weapons. But why were these bombs not used? Von Krantz gives the following answer - there was no carrier, and when the Junkers-390 transport aircraft appeared, the Reich was waiting for betrayal, and besides, these bombs could no longer decide the outcome of the war ...

How plausible is this version? Were the Germans really the first to develop the atomic bomb? It is difficult to say, but one should not exclude such a possibility, because, as we know, it was German specialists who were leaders in atomic research in the early 1940s.

Despite the fact that many historians are investigating the secrets of the Third Reich, because many secret documents have become available, it seems that even today the archives with materials about German military developments reliably store many mysteries.

The development of Soviet nuclear weapons began with the extraction of samples of radium in the early 1930s. In 1939, Soviet physicists Yuli Khariton and Yakov Zel'dovich calculated the chain reaction of nuclear fission of heavy atoms. The following year, scientists from the Ukrainian Institute of Physics and Technology submitted applications for the creation of an atomic bomb, as well as methods for producing uranium-235. For the first time, researchers proposed using conventional explosives as a means to ignite the charge, which would create a critical mass and start a chain reaction.

However, the invention of the Kharkov physicists had its shortcomings, and therefore their application, having managed to visit various authorities, was ultimately rejected. The decisive word was left to the director of the Radium Institute of the USSR Academy of Sciences, Academician Vitaly Khlopin: “... the application has no real basis. In addition, there is in fact a lot of fantastic in it ... Even if it were possible to realize a chain reaction, then the energy that is released is better used to drive engines, for example, aircraft.

The appeals of scientists on the eve of the Great Patriotic War to the people's commissar for defense, Sergei Timoshenko, also turned out to be fruitless. As a result, the project of the invention was buried on a shelf labeled "top secret".

In 1990, journalists asked Vladimir Shpinel, one of the authors of the bomb project: “If your proposals in 1939-1940 were duly appreciated at the government level and you were given support, when could the USSR have atomic weapons?”

“I think that with such opportunities that Igor Kurchatov later had, we would have received it in 1945,” Spinel replied.

However, it was Kurchatov who managed to use in his developments the successful American schemes for creating a plutonium bomb obtained by Soviet intelligence.

nuclear race

With the beginning of the Great Patriotic War, nuclear research was temporarily stopped. The main scientific institutes of the two capitals were evacuated to remote regions.

The head of strategic intelligence, Lavrenty Beria, was aware of the developments of Western physicists in the field of nuclear weapons. For the first time, the Soviet leadership learned about the possibility of creating a superweapon from the "father" of the American atomic bomb, Robert Oppenheimer, who visited the Soviet Union in September 1939. In the early 1940s, both politicians and scientists realized the reality of obtaining a nuclear bomb, as well as the fact that its appearance in the arsenal of the enemy would endanger the security of other powers.

In 1941, the Soviet government received the first intelligence from the United States and Great Britain, where active work had already begun on the creation of a superweapon. The main informant was the Soviet "atomic spy" Klaus Fuchs, a German physicist involved in the US and British nuclear programs.

Academician of the Academy of Sciences of the USSR, physicist Pyotr Kapitsa
RIA News
V. Noskov

Academician Pyotr Kapitsa, speaking on October 12, 1941 at an anti-fascist rally of scientists, stated: “Explosives are one of the important means of modern warfare. Science indicates the fundamental possibility of increasing the explosive force by 1.5-2 times ... Theoretical calculations show that if a modern powerful bomb can, for example, destroy an entire quarter, then an atomic bomb of even a small size, if it is feasible, could easily destroy a major metropolitan city with several million inhabitants. My personal opinion is that the technical difficulties that stand in the way of using intra-atomic energy are still very great. So far, this case is still doubtful, but it is very likely that there are great opportunities here.

In September 1942, the Soviet government adopted a resolution "On the organization of work on uranium". In the spring of the following year, Laboratory No. 2 of the USSR Academy of Sciences was created to produce the first Soviet bomb. Finally, on February 11, 1943, Stalin signed the decision of the GKO on the program of work to create an atomic bomb. At first, the deputy chairman of the GKO, Vyacheslav Molotov, was assigned to lead the important task. It was he who had to find the scientific director of the new laboratory.

Molotov himself, in a note dated July 9, 1971, recalls his decision as follows: “We have been working on this topic since 1943. I was instructed to answer for them, to find such a person who could carry out the creation of an atomic bomb. The Chekists gave me a list of reliable physicists who could be relied upon, and I chose. He summoned Kapitsa to himself, an academician. He said that we were not ready for this and that the atomic bomb was not a weapon of this war, but a matter for the future. Ioffe was asked - he, too, somehow vaguely reacted to this. In short, I had the youngest and still unknown Kurchatov, he was not given a go. I called him, we talked, he made a good impression on me. But he said he still had a lot of ambiguities. Then I decided to give him the materials of our intelligence - the intelligence officers did a very important job. Kurchatov spent several days in the Kremlin, with me, over these materials.

The next couple of weeks, Kurchatov thoroughly studied the data obtained by intelligence and drew up an expert opinion: “The materials are of tremendous, invaluable importance for our state and science ... The totality of information indicates the technical possibility of solving the entire uranium problem in a much shorter time than our scientists think who are not familiar with the progress of work on this problem abroad.

In mid-March, Igor Kurchatov took over as scientific director of Laboratory No. 2. In April 1946, for the needs of this laboratory, it was decided to create a design bureau KB-11. The top-secret object was located on the territory of the former Sarov Monastery, a few tens of kilometers from Arzamas.

KB-11 specialists were supposed to create an atomic bomb using plutonium as a working substance. At the same time, in the process of creating the first nuclear weapon in the USSR, domestic scientists relied on the schemes of the US plutonium bomb, which was successfully tested in 1945. However, since the production of plutonium in the Soviet Union was not yet involved, physicists at the initial stage used uranium mined in Czechoslovak mines, as well as in the territories of East Germany, Kazakhstan and Kolyma.

The first Soviet atomic bomb was named RDS-1 ("Special Jet Engine"). A group of specialists led by Kurchatov managed to load a sufficient amount of uranium into it and start a chain reaction in the reactor on June 10, 1948. The next step was to use plutonium.

"This is atomic lightning"

In the plutonium "Fat Man", dropped on Nagasaki on August 9, 1945, American scientists laid 10 kilograms of radioactive metal. The USSR managed to accumulate such a quantity of substance by June 1949. The head of the experiment, Kurchatov, informed the curator of the atomic project, Lavrenty Beria, that he was ready to test the RDS-1 on August 29.

A part of the Kazakh steppe with an area of about 20 kilometers was chosen as a testing ground. In its central part, experts built a metal tower almost 40 meters high. It was on it that the RDS-1 was installed, the mass of which was 4.7 tons.

The Soviet physicist Igor Golovin describes the situation that prevailed at the test site a few minutes before the start of the tests: “Everything is fine. And suddenly, with a general silence, ten minutes before “one”, Beria’s voice is heard: “But nothing will work out for you, Igor Vasilyevich!” - “What are you, Lavrenty Pavlovich! It will definitely work!" - exclaims Kurchatov and continues to watch, only his neck turned purple and his face became gloomy and concentrated.

To Abram Ioyrysh, a prominent scientist in the field of atomic law, Kurchatov’s condition seems similar to a religious experience: “Kurchatov rushed out of the casemate, ran up an earthen rampart and shouted “She!” waved his arms widely, repeating: “She, she!” and a gleam spread across his face. The pillar of the explosion swirled and went into the stratosphere. A shock wave was approaching the command post, clearly visible on the grass. Kurchatov rushed towards her. Flerov rushed after him, grabbed him by the arm, forcibly dragged him into the casemate and closed the door. The author of the biography of Kurchatov, Pyotr Astashenkov, endows his hero with the following words: “This is atomic lightning. Now she is in our hands ... "

Immediately after the explosion, the metal tower collapsed to the ground, and only a funnel remained in its place. A powerful shock wave threw highway bridges a couple of tens of meters away, and the cars that were nearby scattered across the open spaces almost 70 meters from the explosion site.

Once, after another test, Kurchatov was asked: “Are you not worried about the moral side of this invention?”

“You asked a legitimate question,” he replied. But I think it's misdirected. It is better to address it not to us, but to those who unleashed these forces... It is not physics that is terrible, but an adventurous game, not science, but the use of it by scoundrels... When science makes a breakthrough and opens up the possibility for actions that affect millions of people, the need arises to rethink the norms of morality in order to bring these actions under control. But nothing of the sort happened. Rather the opposite. Just think about it - Churchill's speech in Fulton, military bases, bombers along our borders. The intentions are very clear. Science has been turned into an instrument of blackmail and the main determinant of politics. Do you think morality will stop them? And if this is the case, and this is the case, you have to talk to them in their language. Yes, I know that the weapon we have created is an instrument of violence, but we were forced to create it in order to avoid more heinous violence!” - the answer of the scientist in the book of Abram Ioyrysh and nuclear physicist Igor Morokhov "A-bomb" is described.

A total of five RDS-1 bombs were manufactured. All of them were stored in the closed city of Arzamas-16. Now you can see the model of the bomb in the nuclear weapons museum in Sarov (former Arzamas-16).

There are many different political clubs in the world. Big, now already, seven, G20, BRICS, SCO, NATO, European Union, to some extent. However, none of these clubs can boast a unique function - the ability to destroy the world as we know it. The "nuclear club" possesses similar possibilities.

To date, there are 9 countries with nuclear weapons:

Russia;
United Kingdom;
France;
India
Pakistan;
Israel;
DPRK.

Countries are ranked according to the appearance of nuclear weapons in their arsenal. If the list were built by the number of warheads, then Russia would be in first place with its 8,000 units, 1,600 of which can be launched right now. The states are only 700 units behind, but "at hand" they have 320 more charges. "Nuclear club" is a purely conditional concept, in fact there is no club. There are a number of agreements between the countries on non-proliferation and the reduction of stockpiles of nuclear weapons.

The first tests of the atomic bomb, as you know, were carried out by the United States back in 1945. This weapon was tested in the "field" conditions of the Second World War on the inhabitants of the Japanese cities of Hiroshima and Nagasaki. They operate on the principle of division. During the explosion, a chain reaction is started, which provokes the fission of the nuclei into two, with the accompanying release of energy. Uranium and plutonium are mainly used for this reaction. It is with these elements that our ideas about what nuclear bombs are made of are connected. Since uranium occurs in nature only as a mixture of three isotopes, of which only one is capable of supporting such a reaction, it is necessary to enrich uranium. The alternative is plutonium-239, which does not occur naturally and must be produced from uranium.

If a fission reaction takes place in a uranium bomb, then a fusion reaction occurs in a hydrogen bomb - this is the essence of how a hydrogen bomb differs from an atomic bomb. We all know that the sun gives us light, warmth, and one might say life. The same processes that take place in the sun can easily destroy cities and countries. The explosion of a hydrogen bomb was born by the fusion reaction of light nuclei, the so-called thermonuclear fusion. This "miracle" is possible thanks to hydrogen isotopes - deuterium and tritium. That is why the bomb is called a hydrogen bomb. You can also see the name "thermonuclear bomb", from the reaction that underlies this weapon.

After the world saw the destructive power of nuclear weapons, in August 1945, the USSR began a race that continued until its collapse. The United States was the first to create, test and use nuclear weapons, the first to detonate a hydrogen bomb, but the USSR can be credited with the first production of a compact hydrogen bomb that can be delivered to the enemy on a conventional Tu-16. The first US bomb was the size of a three-story house, a hydrogen bomb of this size is of little use. The Soviets received such weapons as early as 1952, while the first "adequate" US bomb was adopted only in 1954. If you look back and analyze the explosions in Nagasaki and Hiroshima, you can conclude that they were not so powerful. . Two bombs in total destroyed both cities and killed, according to various sources, up to 220,000 people. Carpet bombing Tokyo in a day could take the lives of 150-200,000 people without any nuclear weapons. This is due to the low power of the first bombs - only a few tens of kilotons of TNT. Hydrogen bombs were tested with an eye to overcoming 1 megaton or more.

The first Soviet bomb was tested with a claim of 3 Mt, but in the end 1.6 Mt was tested.

The most powerful hydrogen bomb was tested by the Soviets in 1961. Its capacity reached 58-75 Mt, while the declared 51 Mt. "Tsar" plunged the world into a slight shock, in the literal sense. The shock wave circled the planet three times. There was not a single hill left at the test site (Novaya Zemlya), the explosion was heard at a distance of 800 km. The fireball reached a diameter of almost 5 km, the “mushroom” grew by 67 km, and the diameter of its cap was almost 100 km. The consequences of such an explosion in a large city are hard to imagine. According to many experts, it was the test of a hydrogen bomb of such power (the United States at that time had four times less bombs in strength) that was the first step towards signing various treaties to ban nuclear weapons, test them and reduce production. The world for the first time thought about its own security, which was really under threat.

As mentioned earlier, the principle of operation of a hydrogen bomb is based on a fusion reaction. Thermonuclear fusion is the process of fusion of two nuclei into one, with the formation of a third element, the release of a fourth and energy. The forces that repel the nuclei are colossal, so for the atoms to get close enough to merge, the temperature must be simply enormous. Scientists have been puzzling over cold thermonuclear fusion for centuries, trying to bring the fusion temperature down to room temperature, ideally. In this case, humanity will have access to the energy of the future. As for thermonuclear reaction nowadays, it still requires lighting a miniature sun here on Earth to start it - usually bombs use a uranium or plutonium charge to start the fusion.

In addition to the consequences described above from the use of a bomb of tens of megatons, a hydrogen bomb, like any nuclear weapon, has a number of consequences from its use. Some people tend to think that the hydrogen bomb is a "cleaner weapon" than a conventional bomb. Perhaps it has something to do with the name. People hear the word "water" and think that it has something to do with water and hydrogen, and therefore the consequences are not so dire. In fact, this is certainly not the case, because the action of the hydrogen bomb is based on extremely radioactive substances. It is theoretically possible to make a bomb without a uranium charge, but this is impractical due to the complexity of the process, so the pure fusion reaction is "diluted" with uranium to increase power. At the same time, the amount of radioactive fallout grows to 1000%. Everything that enters the fireball will be destroyed, the zone in the radius of destruction will become uninhabitable for people for decades. Radioactive fallout can harm people's health hundreds and thousands of kilometers away. Specific figures, the area of infection can be calculated, knowing the strength of the charge.

However, the destruction of cities is not the worst thing that can happen "thanks" to weapons of mass destruction. After a nuclear war, the world will not be completely destroyed. Thousands of large cities, billions of people will remain on the planet, and only a small percentage of territories will lose their status as “livable”. In the long term, the whole world will be at risk due to the so-called "nuclear winter". Undermining the nuclear arsenal of the "club" can provoke the release into the atmosphere of a sufficient amount of matter (dust, soot, smoke) to "diminish" the brightness of the sun. A veil that can spread across the planet will destroy crops for several years to come, provoking famine and inevitable population decline. There has already been a “year without a summer” in history, after a major volcanic eruption in 1816, so a nuclear winter looks more than real. Again, depending on how the war proceeds, we can get the following types of global climate change:

cooling by 1 degree, will pass unnoticed;
nuclear autumn - cooling by 2-4 degrees, crop failures and increased formation of hurricanes are possible;
an analogue of "a year without summer" - when the temperature dropped significantly, by several degrees per year;
the little ice age - the temperature can drop by 30 - 40 degrees for a considerable time, will be accompanied by depopulation of a number of northern zones and crop failures;
ice age - the development of a small ice age, when the reflection of sunlight from the surface can reach a certain critical level and the temperature will continue to fall, the difference is only in temperature;
irreversible cooling is a very sad version of the ice age, which, under the influence of many factors, will turn the Earth into a new planet.

The nuclear winter theory is constantly being criticized, and its implications seem a little overblown. However, one should not doubt its imminent offensive in any global conflict with the use of hydrogen bombs.

The Cold War is long over, and therefore, nuclear hysteria can only be seen in old Hollywood films and on the covers of rare magazines and comics. Despite this, we may be on the verge of a serious nuclear conflict, if not a big one. All this thanks to the lover of rockets and the hero of the fight against the imperialist habits of the United States - Kim Jong-un. The DPRK hydrogen bomb is still a hypothetical object, only circumstantial evidence speaks of its existence. Of course, the North Korean government constantly reports that they have managed to make new bombs, so far no one has seen them live. Naturally, the States and their allies, Japan and South Korea, are a little more concerned about the presence, even if hypothetical, of such weapons in the DPRK. The reality is that at the moment, the DPRK does not have enough technology to successfully attack the United States, which they announce to the whole world every year. Even an attack on neighboring Japan or the South may not be very successful, if at all, but every year the danger of a new conflict on the Korean peninsula is growing.
