The most powerful nuclear explosions in the USSR. Tsar Bomba or how the Soviet Union showed Kuzka’s mother to the world

Panic covered not only the “decaying West”, but also Soviet scientists, horrified by what they had done. “Tsar Bomba”, aka “Kuzka’s Mother”, aka “Ivan”, aka “Product 602”, still remains the most powerful explosive device that humanity has ever experienced.

It took seven long years of research, design and development to wipe the noses of the capitalists terrible weapon. The creation of an unprecedented 100-megaton superbomb (for comparison: the power of the largest American hydrogen bomb at that time reached “only” 15 megatons, which was already thousands of times more powerful than the bombs dropped on Hiroshima and Nagasaki) was carried out by a group of scientists led by Igor Kurchatov.

In fact, they could have tested a superbomb already in the late 1950s, but they were in no hurry to frighten obvious and imaginary opponents due to the short-term thaw that gripped the cold hearts of the First Secretary of the CPSU Central Committee Nikita Khrushchev and American President Dwight Eisenhower. Blizzard in the early 1960s cold war swirled with new strength: a U-2 reconnaissance plane was shot down near Sverdlovsk, there was unrest in divided Berlin, the revolution in Cuba led to an acute confrontation with the United States.

The last, active phase of work on superweapons entered in the summer of 1961, after the Soviet leader learned about the possibility of creating a 100-megaton thermonuclear bomb by a group already headed by Andrei Sakharov. The leader could not ignore the unprecedented prospects and gave the go-ahead - give them a bomb by the 22nd Congress of the CPSU, that is, by October.

Today, physicists who participated in those events claim that with their work they wanted to stop nuclear war. It is unknown what motives they were really guided by then, but Sakharov wrote a note to Khrushchev in which he spoke out against testing a super-powerful bomb during the current moratorium on testing nuclear weapons. The First Secretary called all the fears and doubts “slobbering,” and at the end of the summer he could not stand it and threatened his capitalist enemies with a 100-megaton bomb. They didn’t make a secret of it.

The Western world shuddered at the mere statement of Nikita Khrushchev. A wave of anti-Soviet movements swept across the United States; a series of videos about protective measures during a nuclear attack were launched on television in the United States; newspapers were full of headlines accusing them of rehearsing the Third World War.

Meanwhile, the creation of “Kuzka’s Mother” went on as usual. Weapons were developed in closed city, V different times known as Kremlev, Arzamas-16 and Sarov. The secret settlement, in which only nuclear physicists lived, was closed from the outside world and was reminiscent of the very communism that was so threatened to be built throughout the planet. They didn’t turn it off here even in the summer hot water, shops were filled with raw smoked sausages, and each family was entitled to spacious free housing almost in heaven. True, the Soviet paradise was strictly guarded by soldiers and barbed wire - it was impossible to come here or leave without permission.

While practical physicists were puzzling over how to make the most destructive weapon in the history of mankind, theorists were coming up with scenarios for its use. And “Ivan,” of course, was intended primarily for the destruction of the “evil empire” represented by the United States.

The question was how to deliver the Tsar Bomba to the territory of the hated enemy. An option was considered Submarine. The bomb was supposed to be detonated off the coast of the United States at a depth of 1 km. The power of the explosion of 100 million tons of TNT should have generated a tsunami half a kilometer high and 10 kilometers wide. After calculations, however, it turned out that America would have been saved by a continental shelf - only structures at a distance of no more than 5 km from the coast would have been in danger.

Even today it sounds fantastic, but physicists seriously considered the possibility of launching a bomb into Earth orbit. It could be directed at the United States directly from space. They say that theoretically the project was quite feasible, although it would have been incredibly expensive.

However, all these were questions of the distant and gloomy future. In the meantime, it was necessary to assemble the bomb itself. “Product 602” had a three-stage design. The first stage nuclear charge had a power of one and a half megatons and was designed to launch a thermo nuclear reaction in the second, the power of which reached 50 megatons. The third stage provided the same amount for the fission of uranium-238 nuclei.

Having calculated the consequences of the explosion of such a charge and the area of ​​the subsequent radioactive contamination, they decided to replace the uranium elements in the third stage with lead. Thus, the estimated power of the bomb was reduced to 51.5 megatons.

Khrushchev explained this with his characteristic humor: “If we detonate a bomb with a capacity of 100 million tons where it is needed, it can break our windows too.”

The results of the scientists' work are impressive! The length of the weapon exceeded 8 meters, the diameter was 2, and the weight was 26 tons. There was no suitable crane to transport Ivan, so a separate railway line had to be built directly to the workshop where the bomb was assembled. From there the product set off on its penultimate journey - to the harsh polar Olenegorsk.

Not far from the city, at the Olenya airbase, a Tu-95 specially modified for it was waiting for the “Tsar Bomb”. The weapon did not fit on the plane, so part of the fuselage had to be cut out. To bring “Kuzkina-Mother” under the bomb bay, a pit was dug under it. The bomb still could not completely hide in the bowels of the ship and two-thirds of it was visible outside.

The crew was in great danger. The probability that he would remain completely unharmed as a result of the tests was only 1%. To increase the pilots' chances of survival, the plane was painted with white reflective paint, which was supposed to prevent the Tu-95B from catching fire (this is the name, the first and only, given to the aircraft adapted for transporting Ivan). A parachute the size of half a football field was placed in the tail of the bomb. His mission was to slow down the fall of the projectile to give the crew as much time as possible to escape the affected area.

On the morning of October 30, 1961, on the penultimate day of the XXII Congress of the CPSU, a plane with a terrible cargo took off from the Olenya airfield towards the Sukhoi Nos test site on Novaya Zemlya. At 11:32 a.m. the bomb was dropped from a height of 10.5 km. The explosion occurred at an altitude of 4 km. In the few minutes that the crew had, the plane managed to fly a distance of 45 km.

This, of course, was not enough to avoid feeling the wrath of the “Tsar Bomba” at all. A second after the explosion, a man-made sun blossomed above the earth - the flash could have been seen with simple binoculars even from Mars, and on Earth it was observed at a distance of 1000 km. A few seconds later, the diameter of the dust column of the nuclear mushroom grew to 10 km, and its top entered the mesosphere, rushing upward to 67 km.

Flash explosion

According to the pilots, at first it became unbearably hot in the cockpit. Then the plane was overtaken by the first shock wave, spreading at a speed of more than 1000 km/h. The ship, as if hit by a huge club, was thrown half a kilometer. Radio communication was lost throughout the entire Arctic for almost an hour. Fortunately, no one was hurt from the explosion - the pilots survived.

Observing the first consequences of the explosion, some Soviet physicists were afraid that an irreversible nuclear reaction had begun in the atmosphere - the fiery glow had been blazing for a very long time. Perhaps no one could predict the exact results of the tests. Serious scientists expressed the most ridiculous fears, even to the point that Product 602 would split the planet or melt the ice in the Arctic Ocean.

None of this happened. But the power of the explosion would have been enough to wipe out Washington and a dozen surrounding cities from the face of the Earth, while New York, Richmond and Baltimore would have suffered. Any metropolis could disappear, the center of which would completely evaporate, and the outskirts would turn into small rubble blazing in fire. It’s scary to imagine what the consequences could have been if the power of the explosion had been the initially planned 100 megatons...

Total blast zone superimposed on Paris

The rehearsal for the end of the world was a great success. The Tsar Bomba was never put into service: in order to use it in combat conditions, they did not come up with a suitable invulnerable carrier - you cannot install such a huge thing on a rocket, and the plane will be shot down long before approaching the target.

After the test was completed, everyone involved received what they deserved. For some - the title of Hero of the USSR, for the military - promotion, for scientists - recognition and generous bonuses. Exactly a year later, the Cuban Missile Crisis broke out, almost pushing the fragile world into the mouth of another world war. A year later, the American president would be shot by Lee Harvey Oswald, and in the fall of 1964 it would come to the removal of Nikita Khrushchev.

What about the people? The people who learned about some kind of “Tsar Bomb” later than the Americans still went to work, saved money and stood in line for Moskvich, got used to casseroles made from crackers, bread cards and other delights of the food crisis. The Soviet Union threatened the world with a nuclear club and asked America to sell tens of millions of tons of grain for food.

At first it was planned to create a bomb weighing 40 tons. But the designers of the Tu-95 (which was supposed to deliver the bomb to the crash site) rejected this idea immediately. An airplane with such a load simply would not be able to fly to the test site. The target mass of the "superbomb" was reduced.

However, the large dimensions and enormous power of the bomb (originally planned to be eight meters long, two meters in diameter and weighing 26 tons) required significant modifications to the Tu-95. The result was, in fact, a new, and not just a modified version of the old aircraft, designated Tu-95-202 (Tu-95V). The Tu-95-202 aircraft was equipped with two additional control panels: one to control the automation of the “product”, the other to control its heating system. The problem of suspending the aerial bomb turned out to be very difficult, since due to its dimensions it did not fit into the bomb bay of the aircraft. For its suspension, a special device was designed that ensured the lifting of the “product” to the fuselage and securing it to three synchronously controlled locks.

All electrical connectors on the plane were replaced, and the wings and fuselage were covered with reflective paint.

To ensure the safety of the carrier aircraft, Moscow parachute equipment designers developed a special system of six parachutes (the area of ​​the largest was 1.6 thousand square meters). They were thrown out of the rear part of the bomb body one after another and slowed down the descent of the bomb, so that the plane had time to move to a safe distance by the time of the explosion.

By 1959, the carrier of the superbomb was created, but due to some warming of relations between the USSR and the USA, it did not come to practical tests. The Tu-95-202 was first used as a training aircraft at an airfield in the city of Engels, and then was written off as unnecessary.

However, in 1961, with the beginning of a new round of the Cold War, testing of the “superbomb” again became relevant. After the adoption of a decree of the USSR Government on the resumption of nuclear charge testing in July 1961, emergency work began at KB-11 (now the Russian Federal Nuclear Center - All-Russian Research Institute of Experimental Physics, RFNC-VNIIEF), which in 1960 was entrusted with the further development of a superbomb , where it was given the designation “product 602”. A large number of serious innovations were used in the design of the superbomb itself and its charge. Initially, the charge power was 100 megatons of TNT equivalent. On the initiative of Andrei Sakharov, the charge power was halved.

The carrier aircraft was returned to service after being written off. All connectors in the automatic reset system were urgently replaced, and the cargo compartment doors were removed because The real bomb turned out to be slightly larger in size and weight than the mock-up (the length of the bomb was 8.5 meters, its weight was 24 tons, the parachute system was 800 kilograms).

Particular attention was paid to the special training of the carrier aircraft crew. No one could give the pilots a guarantee of a safe return after dropping the bomb. Experts feared that after the explosion an uncontrolled thermonuclear reaction could occur in the atmosphere.

Nikita Khrushchev announced the upcoming bomb tests in his report on October 17, 1961 at the XXII Congress of the CPSU. The tests were supervised by the State Commission.

On October 30, 1961, a Tu-95B with a bomb on board took off from the Olenya airfield in Murmansk region, headed for a training ground located on the archipelago New Earth in Northern Arctic Ocean. Next, a Tu-16 laboratory aircraft took off to record the explosion phenomena and flew as a wingman behind the carrier aircraft. The entire course of the flight and the explosion itself were filmed from the Tu-95B, from the accompanying Tu-16 and from various points on Earth.

At 11:33 a.m., at the command of the barometric sensor, a bomb dropped from 10,500 meters exploded at an altitude of 4,000 meters. The fireball during the explosion exceeded a radius of four kilometers; it was prevented from reaching the surface of the earth by a powerful reflected shock wave, which threw the fireball off the ground.

The huge cloud formed as a result of the explosion reached a height of 67 kilometers, and the diameter of the dome of hot products was 20 kilometers.

The explosion was so powerful that the seismic wave in the earth's crust, generated by the shock wave, circled the Earth three times. The flash was visible at a distance of more than 1000 kilometers. In an abandoned village located 400 kilometers from the epicenter, trees were torn out, windows were broken and roofs of houses were demolished.

The shock wave threw the carrier aircraft, which by that time was 45 kilometers from the release point, to an altitude of 8000 meters, and for some time after the explosion the Tu-95B was uncontrollable. The crew received some dose of radiation. Due to ionization, communication with the Tu-95V and Tu-16 was lost for 40 minutes. All this time no one knew what happened to the planes and crews. After some time, both planes returned to base; marks were visible on the fuselage of the Tu-95V.

Unlike the American test of the Castro Bravo hydrogen bomb, the explosion of the Tsar Bomba on Novaya Zemlya turned out to be relatively “clean”. The test participants arrived at the point where the thermonuclear explosion occurred within two hours; The radiation level in this place did not pose a great danger. This affected design features Soviet bomb, and also that the explosion occurred at a fairly large distance from the surface.

Based on the results of aircraft and ground measurements, the energy release of the explosion was estimated at 50 megatons of TNT equivalent, which coincided with the calculated value.

The test on October 30, 1961 showed that developments in nuclear weapons could quickly cross a critical limit. The main goal that was set and achieved by this test was to demonstrate the possibility of the USSR creating unlimited thermonuclear charges. This event played a key role in establishing nuclear parity in peace and preventing the use of atomic weapons.

Atomic weapons are the most terrible and majestic invention of mankind. The power of a destructive nuclear wave is so great that it can wipe out not only all life, but even the most reliable structures and buildings. Only one nuclear stockpiles in Russia is enough to completely destroy our planet. And it is not surprising, since the country has the richest stock of atomic weapons after the United States. The Soviet “Kuzkina Mother” or “Tsar Bomba”, tested in 1961, became the most powerful atomic weapons of all times.

The TOP 10 included the most powerful nuclear bombs in the world. Many of them were used for test purposes, but caused irreparable harm to the environment. Others have become weapons in resolving military conflicts.

Yield 18 kilotons

Little boy(“Baby”) is the first nuclear bomb that was not used for testing purposes. It was she who contributed to the end of the war between Japan and the United States. Little boy with a power of 18 kilotons caused the death of 140 thousand residents of Hiroshima. The device, 3 meters long and 70 cm in diameter, created a nuclear column more than 6 kilometers high. “Little Boy” and “Fat Man” who “followed” him brought considerable damage to two Japanese cities, which to this day remain uninhabited.

Yield 21 kilotons

Fat Man(Fat Man) - the second nuclear bomb that the United States used against Japan. Residents of the city of Nagasaki became victims of nuclear weapons. The explosion, with a power of 21 kilotons, claimed the lives of 80 thousand people immediately, and another 35 thousand died from radiation exposure. Exactly this powerful weapon for the entire existence of mankind, which was used for military purposes.

Yield 21 kilotons

(Thing) - the first bomb that marked the beginning of nuclear weapons testing. The shock wave of the explosion was 21 kilotons and rose 11 kilometers into the air as a cloud. The first nuclear explosion in human history made a stunning impression on scientists. White clouds of smoke with a diameter of almost two kilometers quickly rose upward and formed the shape of a mushroom.

Baker Yield 21 kilotons

Baker(Baker) – one of three atomic bombs, who participated in Operation Crossroads in 1946. The tests were carried out to determine the effects of atomic shells on sea vessels and experimental animals. At a depth of 27 meters, an explosion with a power of 23 kilotons was carried out, which displaced about two million tons of water to the surface and formed a column more than half a kilometer in height. "Baker" brought with it "the world's first nuclear disaster." The radioactive island of Bikini, where the tests took place, became uninhabitable and was considered uninhabited until 2010.

Yield 955 kilotons

"- the most powerful atomic bomb tested by France in 1971. A projectile with a yield of 955 kilotons of TNT was detonated on the Mururoa Atoll, which is a nuclear explosion site. More than 200 nuclear weapons were tested there until 1998.

Power 11 megatons

- one of the most powerful explosions, made in the USA. The operation was accepted for execution on March 27, 1954. The explosion was carried out on a barge in the open ocean, as they were afraid that the bomb could destroy a nearby island. The power of the explosion was 11 megatons, instead of the expected 4 megatons. This is explained by the fact that cheap material was used as thermonuclear fuel.

Power 12 megatons

Mike's device(Evie Mike) was initially of no value and was used as an experimental bomb. The height of the nuclear cloud was estimated at 37 km, and the diameter of the cloud cap was about 161 km. The strength of Mike's nuclear wave was estimated at 12 megatons of TNT equivalent. The power of the projectile was enough to wipe out the small islands of Elugelab, where the test was carried out. In their place, only a crater with a diameter of 2 kilometers and a depth of 50 meters remained. Radioactively contaminated fragments from the reefs scattered 50 km from the epicenter of the explosion.

Yield 13.5 megatons

- the second most powerful nuclear explosion produced by American tests. The initial power of the device was expected to be no more than 10 megatons per TNT equivalent. As it turned out, the nuclear explosion was very powerful and was estimated at 13.5 megatons. The height of the stem of the nuclear mushroom was 40 km, and the cap was 16 km. Within four days, the radiation cloud reached Mexico City, which is located 11,000 km from the site of the operation.

Power 15 megatons

Castle Bravo(Shrimp TX -21) - the most powerful atomic bomb ever tested in the United States. The operation was carried out in March 1954 and had irreversible consequences. The explosion, with a power of 15 megatons, caused severe radiation contamination. Hundreds of people living in the Marshall Islands were exposed to radiation. The stem of the nuclear mushroom exceeded 40 km, and the diameter of the cap was estimated at 100 km. The explosion caused the formation of seabed a huge crater, 2 km in diameter. The consequences that resulted from the tests became the reason for limiting operations carried out with nuclear projectiles.

Yield 58 megatons

(AN602) is the most powerful Soviet nuclear bomb in the world of all time. An eight-meter projectile with a diameter of two meters was used as a test in 1961 on the Novaya Zemlya archipelago. It was originally planned that AN602 would have a power of 100 megatons, but fearing global destructive force weapons, agreed that the force of the explosion would not exceed 58 megatons. At an altitude of 4 km, the Tsar Bomba was activated and gave stunning results. The diameter of the fire cloud reached about 10 km. The nuclear pillar was about 67 km in height, and the diameter of the pillar cap reached 97 km. Even being at a distance of 400 km from the epicenter of the explosion was extremely life-threatening. A powerful sound wave spread over almost a thousand kilometers. On the island where the test took place, there were no traces of life or any buildings left; absolutely everything was leveled to the surface of the earth. The seismic wave of the explosion circled the entire planet three times, and every inhabitant of the planet was able to feel the full power of nuclear weapons. After this test, more than a hundred countries signed an agreement to stop this type of operations both in the atmosphere, under water and on land.

Tsar Bomba is the name of the AN602 hydrogen bomb, which was tested in the Soviet Union in 1961. This bomb was the most powerful ever detonated. Its power was such that the flash from the explosion was visible 1000 km away, and the nuclear mushroom rose almost 70 km.

The Tsar Bomba was a hydrogen bomb. It was created in Kurchatov's laboratory. The power of the bomb was such that it would have been enough to destroy 3800 Hiroshimas.

Let's remember the history of its creation.

At the beginning of the “atomic age,” the United States and the Soviet Union entered into a race not only in the number of atomic bombs, but also in their power.

The USSR, which acquired atomic weapons later than its competitor, sought to level the situation by creating more advanced and more powerful devices.

The development of a thermonuclear device codenamed “Ivan” was started in the mid-1950s by a group of physicists led by Academician Kurchatov. The group involved in this project included Andrei Sakharov, Viktor Adamsky, Yuri Babaev, Yuri Trunov and Yuri Smirnov.

During research work scientists also tried to find the limits of the maximum power of a thermonuclear explosive device.

The theoretical possibility of obtaining energy by thermonuclear fusion was known even before World War II, but it was the war and the subsequent arms race that raised the question of creating technical device to practically create this reaction. It is known that in Germany in 1944, work was carried out to initiate thermonuclear fusion by compressing nuclear fuel using charges of conventional explosives - but they were not successful, since it was not possible to obtain the required temperatures and pressures. The USA and the USSR have been developing thermonuclear weapons since the 40s, almost simultaneously testing the first thermonuclear devices in the early 50s. In 1952, the United States exploded a charge with a yield of 10.4 megatons on the Eniwetak Atoll (which is 450 times more powerful than the bomb dropped on Nagasaki), and in 1953, the USSR tested a device with a yield of 400 kilotons.

The designs of the first thermonuclear devices were poorly suited for real combat use. For example, the device tested by the United States in 1952 was a ground-based structure the height of a 2-story building and weighing over 80 tons. Liquid thermonuclear fuel was stored in it using a huge refrigeration unit. Therefore, in the future, serial production of thermonuclear weapons was carried out using solid fuel- lithium-6 deuteride. In 1954, the United States tested a device based on it at Bikini Atoll, and in 1955, a new Soviet thermonuclear bomb was tested at the Semipalatinsk test site. In 1957, tests of a hydrogen bomb were carried out in Great Britain.

Design research lasted for several years, and the final stage of development of “product 602” occurred in 1961 and took 112 days.

The AN602 bomb had a three-stage design: the nuclear charge of the first stage (calculated contribution to the explosion power is 1.5 megatons) triggered a thermonuclear reaction in the second stage (contribution to the explosion power - 50 megatons), and it, in turn, initiated the so-called nuclear “ Jekyll-Hyde reaction" (nuclear fission in uranium-238 blocks under the influence fast neutrons, formed as a result of the thermonuclear fusion reaction) in the third stage (another 50 megatons of power), so that the total calculated power of AN602 was 101.5 megatons.

However, the original option was rejected, since in this form it would have caused extremely powerful radiation contamination (which, however, according to calculations, would still have been seriously inferior to that caused by much less powerful American devices).
As a result, it was decided not to use the “Jekyll-Hyde reaction” in the third stage of the bomb and to replace the uranium components with their lead equivalent. This reduced the estimated total power of the explosion by almost half (to 51.5 megatons).

Another limitation for the developers was the capabilities of aircraft. The first version of a bomb weighing 40 tons was rejected by aircraft designers from the Tupolev Design Bureau - the carrier aircraft would not be able to deliver such a cargo to the target.

As a result, the parties reached a compromise - nuclear scientists reduced the weight of the bomb by half, and aviation designers were preparing a special modification of the Tu-95 bomber for it - the Tu-95V.

It turned out that it would not be possible to place a charge in the bomb bay under any circumstances, so the Tu-95V had to carry the AN602 to the target on a special external sling.

In fact, the carrier aircraft was ready in 1959, but nuclear physicists were instructed not to speed up work on the bomb - just at that moment there were signs of a decrease in tension in international relations in the world.

At the beginning of 1961, however, the situation worsened again, and the project was revived.

The final weight of the bomb including the parachute system was 26.5 tons. The product had several names at once - “Big Ivan”, “Tsar Bomba” and “Kuzka’s Mother”. The latter stuck to the bomb after Soviet leader Nikita Khrushchev’s speech to the Americans, in which he promised to show them “Kuzka’s mother.”

In 1961, Khrushchev quite openly spoke to foreign diplomats about the fact that the Soviet Union was planning to test a super-powerful thermonuclear charge in the near future. On October 17, 1961, the Soviet leader announced the upcoming tests in a report at the XXII Party Congress.

The test site was determined to be the Sukhoi Nos test site on Novaya Zemlya. Preparations for the explosion were completed in last days October 1961.

The Tu-95B carrier aircraft was based at the airfield in Vaenga. Here, in a special room, final preparations for testing were carried out.

On the morning of October 30, 1961, the crew of pilot Andrei Durnovtsev received an order to fly to the test site area and drop a bomb.

Taking off from the airfield in Vaenga, the Tu-95B reached its design point two hours later. Bomb on parachute system was dropped from a height of 10,500 meters, after which the pilots immediately began to move the car away from the dangerous area.

At 11:33 Moscow time, an explosion was carried out at an altitude of 4 km above the target.

The power of the explosion significantly exceeded the calculated one (51.5 megatons) and ranged from 57 to 58.6 megatons in TNT equivalent.

Operating principle:

The action of a hydrogen bomb is based on the use of energy released during the thermonuclear fusion reaction of light nuclei. It is this reaction that takes place in the depths of stars, where, under the influence of ultra-high temperatures and enormous pressure, hydrogen nuclei collide and merge into heavier helium nuclei. During the reaction, part of the mass of hydrogen nuclei is converted into a large number of energy - thanks to this, stars release huge amounts of energy constantly. Scientists copied this reaction using isotopes of hydrogen - deuterium and tritium, which gave it the name "hydrogen bomb". Initially, liquid isotopes of hydrogen were used to produce charges, and later lithium-6 deuteride, a solid compound of deuterium and an isotope of lithium, was used.

Lithium-6 deuteride is the main component of the hydrogen bomb, thermonuclear fuel. It already stores deuterium, and the lithium isotope serves as the raw material for the formation of tritium. To start a thermonuclear fusion reaction, it is necessary to create high temperature and pressure, and also to isolate tritium from lithium-6. These conditions are provided as follows.

The shell of the container for thermonuclear fuel is made of uranium-238 and plastic, and a conventional nuclear charge with a power of several kilotons is placed next to the container - it is called a trigger, or initiator charge of a hydrogen bomb. During the explosion of the plutonium initiator charge under the influence of powerful X-ray radiation, the container shell turns into plasma, compressing thousands of times, which creates the necessary high pressure and enormous temperature. At the same time, neutrons emitted by plutonium interact with lithium-6, forming tritium. Deuterium and tritium nuclei interact under the influence of ultra-high temperature and pressure, which leads to a thermonuclear explosion.

If you make several layers of uranium-238 and lithium-6 deuteride, then each of them will add its own power to the explosion of a bomb - that is, such a “puff” allows you to increase the power of the explosion almost unlimitedly. Thereby hydrogen bomb can be made of almost any power, and it will be much cheaper than a conventional nuclear bomb of the same power.

Witnesses of the test say that they have never seen anything like this in their lives. The nuclear mushroom of the explosion rose to a height of 67 kilometers, the light radiation could potentially cause third-degree burns at a distance of up to 100 kilometers.

Observers reported that at the epicenter of the explosion, the rocks took a surprisingly flat shape, and the ground turned into some kind of military parade ground. Complete destruction was achieved over an area equal to the territory of Paris.

Ionization of the atmosphere caused radio interference even hundreds of kilometers from the test site for about 40 minutes. The lack of radio communication convinced the scientists that the tests went as well as possible. The shock wave resulting from the explosion of the Tsar Bomba circled three times Earth. The sound wave generated by the explosion reached Dikson Island at a distance of about 800 kilometers.

Despite the heavy clouds, witnesses saw the explosion even at a distance of thousands of kilometers and could describe it.

Radioactive contamination from the explosion turned out to be minimal, as the developers had planned - more than 97% of the power of the explosion was provided by the thermonuclear fusion reaction, which practically did not create radioactive contamination.

This allowed scientists to begin studying the test results on the experimental field within two hours after the explosion.

The explosion of the Tsar Bomba really made an impression on the whole world. She turned out to be more powerful than the most powerful American bomb four times.

There was a theoretical possibility of creating even more powerful charges, but it was decided to abandon the implementation of such projects.

Oddly enough, the main skeptics turned out to be the military. From their point of view, such weapons had no practical meaning. How do you order him to be delivered to the “den of the enemy”? The USSR already had missiles, but they were unable to fly to America with such a load.

Strategic bombers were also unable to fly to the United States with such “luggage.” In addition, they became easy targets for air defense systems.

Atomic scientists turned out to be much more enthusiastic. Plans were put forward to place several super-bombs with a capacity of 200–500 megatons off the coast of the United States, the explosion of which would cause a giant tsunami that would literally wash away America.

Academician Andrei Sakharov, future human rights activist and laureate Nobel Prize peace, put forward another plan. “The carrier could be a large torpedo launched from a submarine. I fantasized that it was possible to develop a direct-flow water-steam nuclear power plant for such a torpedo. jet engine. The target of an attack from a distance of several hundred kilometers should be enemy ports. A war at sea is lost if the ports are destroyed, the sailors assure us of this. The body of such a torpedo can be very durable; it will not be afraid of mines and barrage nets. Of course, the destruction of ports - both by a surface explosion of a torpedo with a 100-megaton charge that “jumped out” of the water, and by an underwater explosion - is inevitably associated with very large casualties,” the scientist wrote in his memoirs.

Sakharov told Vice Admiral Pyotr Fomin about his idea. An experienced sailor, who headed the “atomic department” under the Commander-in-Chief of the USSR Navy, was horrified by the scientist’s plan, calling the project “cannibalistic.” According to Sakharov, he was ashamed and never returned to this idea.

Scientists and military personnel received generous awards for the successful testing of the Tsar Bomba, but the very idea of ​​super-powerful thermonuclear charges began to become a thing of the past.

Nuclear weapons designers focused on things less spectacular, but much more effective.

And the explosion of the “Tsar Bomba” to this day remains the most powerful of those ever produced by humanity.

Tsar Bomba in numbers:

Weight: 27 tons
Length: 8 meters
Diameter: 2 meters
Yield: 55 megatons of TNT
Mushroom height: 67 km
Mushroom base diameter: 40 km
Fireball diameter: 4.6 km
Distance at which the explosion caused skin burns: 100 km
Explosion visibility distance: 1000 km
The amount of TNT required to equal the power of the Tsar Bomb: a giant TNT cube with a side of 312 meters (the height of the Eiffel Tower).
