Thermonuclear bombs can be hundreds or even thousands of times more powerful than atomic bombs. The explosive yield of atomic bombs is measured in kilotons, each unit of which equals the explosive force of 1, tons of TNT.

The explosive power of hydrogen bombs, by contrast, is frequently expressed in megatons , each unit of which equals the explosive force of 1,, tons of TNT.

Hydrogen bombs of more than 50 megatons have been detonated, but the explosive power of the weapons mounted on strategic missiles usually ranges from kilotons to 1.

Thermonuclear bombs can be made small enough a few feet long to fit in the warheads of intercontinental ballistic missiles ; these missiles can travel almost halfway across the globe in 20 or 25 minutes and have computerized guidance systems so accurate that they can land within a few hundred yards of a designated target.

Edward Teller , Stanislaw M. Ulam , and other American scientists developed the first hydrogen bomb, which was tested at Enewetak atoll on November 1, The U.

Alternative Titles: H-bomb, hydrogen bomb. Instead of continuing with its own design, the British were given access to the design of the smaller American Mk 28 warhead and were able to manufacture copies.

British access to nuclear weapons information was cut-off by the United States at one point due to concerns about Soviet espionage.

Full cooperation was not reestablished until an agreement governing the handling of secret information and other issues was signed.

The People's Republic of China detonated its first hydrogen thermonuclear bomb on June 17, , 32 months after detonating its first fission weapon, with a yield of 3.

A story in The New York Times by William Broad [35] reported that in , a supposed Chinese double agent delivered information indicating that China knew secret details of the U.

W88 warhead, supposedly through espionage. France 's journey in building nuclear weapons began prior to World War II in The development of nuclear weapons was slowed during the country's German invasion.

The United States did not want France to acquire expert knowledge about nuclear weaponry, which ultimately led to the Alsos Mission.

The missions followed closely behind the advancing forward-front to obtain information about how close Germany was to building an atomic weapon.

Following the surrender of the Nazis, Germany was divided into "zones of occupation". The "zone" given to the French was suspected to contain several nuclear research facilities.

The United States conducted Operation Harborage to seize any and all information about nuclear weaponry from the French.

The Operation strategized to have American troops intercede advancing French army, allowing the Americans to seize any German scientists or records as well as destroy the remaining functional facilities.

However it was not until that a tangible goal of building plutonium reactors progressed. Two years later, a reactor was being built and a plutonium separating plant began construction shortly after.

In the question about continuing to explore building an atomic bomb was raised. Ultimately, the Prime Minister decided to continue efforts developing an atomic bomb in secret.

In late , tasks were delegated between the CEA and Defense Ministry to propel atomic development such as finding a test site, providing the necessary uranium, and physical device assembly.

Charles de Gaulle returned to power and was elected France's Fifth Republic's first president in De Gaulle, a strong believer in the nuclear weapons program, approved the country's first nuclear test to take place in one of the early months of It was called " Gerboise Bleue ", translating to "Blue jerboa ".

The bomb used a plutonium implosion design with a yield of 70 kilotons. The French nuclear testing site was moved to the unpopulated French atolls in the Pacific Ocean.

The first test conducted at these new sites was the "Canopus" test in the Fangataufa atoll in French Polynesia on 24 August , the country's first multistage thermonuclear weapon test.

The bomb was detonated from a balloon at a height of metres. The result of this test was significant atmospheric contamination.

France reportedly had great difficulty with its initial development of the Teller-Ulam design, but it later overcame these, and is believed to have nuclear weapons equal in sophistication to the other major nuclear powers.

France and China did not sign or ratify the Partial Nuclear Test Ban Treaty of , which banned nuclear test explosions in the atmosphere, underwater, or in outer space.

Between and France carried out more than nuclear tests. France signed the Comprehensive Nuclear-Test-Ban Treaty that same year, and then ratified the Treaty within two years.

France confirmed that its nuclear arsenal contains about warheads, carried by submarine-launched ballistic missiles SLBMs and fighter-bombers in France has four Triomphant-class ballistic missile submarines.

One ballistic missile submarine is deployed in the deep ocean, but a total of three must be in operational use at all times.

The three older submarines are armed with 16 M45 missiles. The newest submarine, "Le Terrible" , was commissioned in , and it has M51 missiles capable of carrying TN 75 thermonuclear warheads.

The air fleet is four squadrons at four different bases. In total, there are 23 Mirage N aircraft and 20 Rafales capable of carrying nuclear warheads.

France's nuclear program has been carefully designed to ensure that these weapons remain usable decades into the future. On May 11, , India announced that it had detonated a thermonuclear bomb in its Operation Shakti tests "Shakti-I", specifically.

Samar Mubarakmand , a Pakistani nuclear physicist, asserted that if Shakti-I had been a thermonuclear test, the device had failed to fire.

Harold M. Agnew , former director of the Los Alamos National Laboratory , said that India's assertion of having detonated a staged thermonuclear bomb was believable.

Rajagopal Chidambaram , former chairman of the Atomic Energy Commission of India said that India has the capability to build thermonuclear bombs of any yield at will.

The yield of India's hydrogen bomb test remains highly debatable among the Indian science community and the international scholars.

In an interview in August , the director for the test site preparations, Dr. Santhanam claimed that the yield of the thermonuclear explosion was lower than expected and that India should therefore not rush into signing the CTBT.

Other Indian scientists involved in the test have disputed Dr. Santhanam's claim, [51] arguing that Santhanam's claims are unscientific.

India officially maintains that it can build thermonuclear weapons of various yields up to around kilotons on the basis of the Shakti-1 thermonuclear test.

Israel is alleged to possess thermonuclear weapons of the Teller—Ulam design, [54] but it is not known to have tested any nuclear devices, although it is widely speculated that the Vela Incident of may have been a joint Israeli—South African nuclear test.

It is well established that Edward Teller advised and guided the Israeli establishment on general nuclear matters for some twenty years.

Congress , after receiving credible information from an "American scientist" Teller , on Israel's nuclear capability.

North Korea claimed to have tested its miniaturised thermonuclear bomb on 6 January North Korea's first three nuclear tests , and were relatively low yield and do not appear to have been of a thermonuclear weapon design.

In , the South Korean Defense Ministry speculated that North Korea may be trying to develop a "hydrogen bomb" and such a device may be North Korea's next weapons test.

These seismic recordings cast doubt upon North Korea's claim that a hydrogen bomb was tested and suggest it was a non-fusion nuclear test.

On 3 September , the country's state media reported that a hydrogen bomb test was conducted which resulted in "perfect success".

According to the U. Intelligence released an early assessment that the yield estimate was kilotons, [66] with an uncertainty range of 70 to kilotons.

Its yield estimate was revised to kilotons, while noting the estimate had some uncertainty and an undisclosed margin of error.

The Teller—Ulam design was for many years considered one of the top nuclear secrets, and even today it is not discussed in any detail by official publications with origins "behind the fence" of classification.

United States Department of Energy DOE policy has been, and continues to be, that they do not acknowledge when "leaks" occur, because doing so would acknowledge the accuracy of the supposed leaked information.

Aside from images of the warhead casing, most information in the public domain about this design is relegated to a few terse statements by the DOE and the work of a few individual investigators.

In the United States government declassified a document stating "[I]n thermonuclear TN weapons, a fission 'primary' is used to trigger a TN reaction in thermonuclear fuel referred to as a 'secondary'", and in added, "[I]n thermonuclear weapons, radiation from a fission explosive can be contained and used to transfer energy to compress and ignite a physically separate component containing thermonuclear fuel.

Whether these statements vindicate some or all of the models presented above is up for interpretation, and official U. Other information, such as the types of fuel used in some of the early weapons, has been declassified, though precise technical information has not been.

Most of the current ideas on the workings of the Teller—Ulam design came into public awareness after the Department of Energy DOE attempted to censor a magazine article by U.

In , Morland had decided that discovering and exposing this "last remaining secret" would focus attention onto the arms race and allow citizens to feel empowered to question official statements on the importance of nuclear weapons and nuclear secrecy.

Morland eventually concluded that the "secret" was that the primary and secondary were kept separate and that radiation pressure from the primary compressed the secondary before igniting it.

When an early draft of the article, to be published in The Progressive magazine, was sent to the DOE after falling into the hands of a professor who was opposed to Morland's goal, the DOE requested that the article not be published, and pressed for a temporary injunction.

The DOE argued that Morland's information was 1 likely derived from classified sources, 2 if not derived from classified sources, itself counted as "secret" information under the " born secret " clause of the Atomic Energy Act , and 3 was dangerous and would encourage nuclear proliferation.

Morland and his lawyers disagreed on all points, but the injunction was granted, as the judge in the case felt that it was safer to grant the injunction and allow Morland, et al.

The Progressive Through a variety of more complicated circumstances, the DOE case began to wane as it became clear that some of the data they were attempting to claim as "secret" had been published in a students' encyclopedia a few years earlier.

After another H-bomb speculator, Chuck Hansen , had his own ideas about the "secret" quite different from Morland's published in a Wisconsin newspaper, the DOE claimed that The Progressive case was moot, dropped its suit, and allowed the magazine to publish its article, which it did in November Morland had by then, however, changed his opinion of how the bomb worked, suggesting that a foam medium the polystyrene rather than radiation pressure was used to compress the secondary , and that in the secondary there was a spark plug of fissile material as well.

He published these changes, based in part on the proceedings of the appeals trial, as a short erratum in The Progressive a month later.

Morland's work is interpreted as being at least partially correct because the DOE had sought to censor it, one of the few times they violated their usual approach of not acknowledging "secret" material that had been released; however, to what degree it lacks information, or has incorrect information, is not known with any confidence.

The difficulty that a number of nations had in developing the Teller—Ulam design even when they apparently understood the design, such as with the United Kingdom , makes it somewhat unlikely that this simple information alone is what provides the ability to manufacture thermonuclear weapons.

Nevertheless, the ideas put forward by Morland in have been the basis for all the current speculation on the Teller—Ulam design.

In January , Soviet leader Mikhail Gorbachev publicly proposed a three-stage program for abolishing the world's nuclear weapons by the end of the 20th century.

Sakharov —89 was recruited into the Soviet Union's nuclear weapons program in , a year after he completed his doctorate. In the US detected the first Soviet test of a fission bomb, and the two countries embarked on a desperate race to design a thermonuclear hydrogen bomb that was a thousand times more powerful.

Like his US counterparts, Sakharov justified his H-bomb work by pointing to the danger of the other country's achieving a monopoly.

But also like some of the US scientists who had worked on the Manhattan Project, he felt a responsibility to inform his nation's leadership and then the world about the dangers from nuclear weapons.

Self-publishing was the method at the time for spreading unapproved manuscripts in the Soviet Union. Many readers would create multiple copies by typing with multiple sheets of paper interleaved with carbon paper.

After the essay was published, Sakharov was barred from returning to work in the nuclear weapons program and took a research position in Moscow.

More than a year and a half later, he persuaded the Politburo, the party's executive committee, to allow Sakharov and Bonner to return to Moscow.

Sakharov was elected as an opposition member to the Soviet Congress of People's Deputies in Later that year he had a cardiac arrhythmia and died in his apartment.

He left behind a draft of a new Soviet constitution that emphasized democracy and human rights. On 5 February , during a training mission flown by a B , a Mark 15 nuclear bomb , also known as the Tybee Bomb , was lost off the coast of Tybee Island near Savannah, Georgia.

The bomb was thought by the Department of Energy to lie buried under several feet of silt at the bottom of Wassaw Sound.

The conventional explosives in two of the Mk28 -type hydrogen bombs detonated upon impact with the ground, dispersing plutonium over nearby farms.

In his book Dark Sun: The Making of the Hydrogen Bomb , author Richard Rhodes describes in detail the internal components of the " Ivy Mike " Sausage device, based on information obtained from extensive interviews with the scientists and engineers who assembled it.

According to Rhodes, the actual mechanism for the compression of the secondary was a combination of the radiation pressure, foam plasma pressure, and tamper-pusher ablation theories described above; the radiation from the primary heated the polyethylene foam lining the casing to a plasma, which then re-radiated radiation into the secondary's pusher, causing its surface to ablate and driving it inwards, compressing the secondary, igniting the sparkplug, and causing the fusion reaction.

The general applicability of this principle is unclear. W88 nuclear warhead, a small MIRVed warhead used on the Trident II SLBM , had a prolate egg or watermelon shaped primary code-named Komodo and a spherical secondary code-named Cursa inside a specially shaped radiation case known as the "peanut" for its shape.

The reentry cones for the W88 and W87 are the same size, 1. Putting the secondary, which is heavier than the primary, in the wider part of the cone allows it to be larger, but it also moves the center of mass aft , potentially causing aerodynamic stability problems during reentry.

To make the primary small enough to fit into the narrow part of the cone, its bulky insensitive high explosive charges must be replaced with more compact "non-insensitive" high explosives that are more hazardous to handle.

The W88 also contains tritium , which has a half life of only From Wikipedia, the free encyclopedia. This section needs additional citations for verification.

Foam plasma mechanism firing sequence. Warhead before firing; primary fission bomb at top, secondary fusion fuel at bottom, all suspended in polystyrene foam.

High-explosive fires in primary, compressing plutonium core into supercriticality and beginning a fission reaction. Fission primary emits X-rays that are scattered along the inside of the casing, irradiating the polystyrene foam.

Polystyrene foam becomes plasma, compressing secondary, and plutonium sparkplug begins to fission. Compressed and heated, lithium-6 deuteride fuel produces tritium and begins the fusion reaction.

The neutron flux produced causes the U tamper to fission. A fireball starts to form. Warhead before firing.

The nested spheres at the top are the fission primary; the cylinders below are the fusion secondary device.

Fission primary's explosives have detonated and collapsed the primary's fissile pit. The primary's fission reaction has run to completion, and the primary is now at several million degrees and radiating gamma and hard X-rays, heating up the inside of the hohlraum and the shield and secondary's tamper.

The primary's reaction is over and it has expanded. The surface of the pusher for the secondary is now so hot that it is also ablating or expanding away, pushing the rest of the secondary tamper, fusion fuel, and fissile spark plug inwards.

The spark plug starts to fission. Not depicted: the radiation case is also ablating and expanding outwards omitted for clarity of diagram.

The secondary's fuel has started the fusion reaction and shortly will burn up. Main article: History of the Teller—Ulam design. Main articles: Ivy Mike and Operation Castle.

Nothing quiets a room like dropping the H-bomb.

Rough calculations for the basic ablation effect are relatively simple: the energy from the primary is distributed evenly onto all of the surfaces within the outer radiation case, with the components coming to a thermal equilibrium , and the effects of that thermal energy are then analyzed.

The velocity at which the surface then expands outwards is calculated and, from a basic Newtonian momentum balance, the velocity at which the rest of the tamper implodes inwards.

The pressure due to the ablating material is calculated to be 5. The calculated ablation pressure is one order of magnitude greater than the higher proposed plasma pressures and nearly two orders of magnitude greater than calculated radiation pressure.

No mechanism to avoid the absorption of energy into the radiation case wall and the secondary tamper has been suggested, making ablation apparently unavoidable.

The other mechanisms appear to be unneeded. Rhodes quotes several designers of that bomb explaining that the plastic foam layer inside the outer case is to delay ablation and thus recoil of the outer case: if the foam were not there, metal would ablate from the inside of the outer case with a large impulse, causing the casing to recoil outwards rapidly.

The purpose of the casing is to contain the explosion for as long as possible, allowing as much X-ray ablation of the metallic surface of the secondary stage as possible, so it compresses the secondary efficiently, maximizing the fusion yield.

Plastic foam has a low density, so causes a smaller impulse when it ablates than metal does. Two special variations exist that will be discussed in a subsequent section: the cryogenically cooled liquid deuterium device used for the Ivy Mike test, and the putative design of the W88 nuclear warhead—a small, MIRVed version of the Teller—Ulam configuration with a prolate egg or watermelon shaped primary and an elliptical secondary.

Most bombs do not apparently have tertiary "stages"—that is, third compression stage s , which are additional fusion stages compressed by a previous fusion stage.

The fissioning of the last blanket of uranium, which provides about half the yield in large bombs, does not count as a "stage" in this terminology.

The U. This U. If any hydrogen bombs have been made from configurations other than those based on the Teller—Ulam design, the fact of it is not publicly known.

A possible exception to this is the Soviet early Sloika design. In essence, the Teller—Ulam configuration relies on at least two instances of implosion occurring: first, the conventional chemical explosives in the primary would compress the fissile core, resulting in a fission explosion many times more powerful than that which chemical explosives could achieve alone first stage.

Second, the radiation from the fissioning of the primary would be used to compress and ignite the secondary fusion stage, resulting in a fusion explosion many times more powerful than the fission explosion alone.

Finally, efficient bombs but not so-called neutron bombs end with the fissioning of the final natural uranium tamper, something that could not normally be achieved without the neutron flux provided by the fusion reactions in secondary or tertiary stages.

Even such large bombs have been replaced by smaller-yield bunker buster type nuclear bombs see more: nuclear bunker buster.

As discussed above, for destruction of cities and non-hardened targets, breaking the mass of a single missile payload down into smaller MIRV bombs, in order to spread the energy of the explosions into a "pancake" area, is far more efficient in terms of area-destruction per unit of bomb energy.

This also applies to single bombs deliverable by cruise missile or other system, such as a bomber, resulting in most operational warheads in the U.

The idea of a thermonuclear fusion bomb ignited by a smaller fission bomb was first proposed by Enrico Fermi to his colleague Edward Teller in at the start of what would become the Manhattan Project.

Stanislaw Ulam , a co-worker of Teller, made the first key conceptual leaps towards a workable fusion design. Ulam's two innovations that rendered the fusion bomb practical were that compression of the thermonuclear fuel before extreme heating was a practical path towards the conditions needed for fusion, and the idea of staging or placing a separate thermonuclear component outside a fission primary component, and somehow using the primary to compress the secondary.

Teller then realized that the gamma and X-ray radiation produced in the primary could transfer enough energy into the secondary to create a successful implosion and fusion burn, if the whole assembly was wrapped in a hohlraum or radiation case.

Indeed, shortly before his death, and in a last-ditch effort to discredit Ulam's contributions, Teller claimed that one of his own "graduate students" had proposed the mechanism.

The "George" shot of Operation Greenhouse of 9 May tested the basic concept for the first time on a very small scale.

On November 1, , the Teller—Ulam configuration was tested at full scale in the " Ivy Mike " shot at an island in the Enewetak Atoll , with a yield of The device, dubbed the Sausage , used an extra-large fission bomb as a "trigger" and liquid deuterium —kept in its liquid state by 20 short tons 18 metric tons of cryogenic equipment—as its fusion fuel, [ citation needed ] and weighed around 80 short tons 70 metric tons altogether.

The liquid deuterium fuel of Ivy Mike was impractical for a deployable weapon, and the next advance was to use a solid lithium deuteride fusion fuel instead.

In this was tested in the " Castle Bravo " shot the device was code-named Shrimp , which had a yield of 15 megatons 2.

Efforts in the United States soon shifted towards developing miniaturized Teller—Ulam weapons that could fit into intercontinental ballistic missiles and submarine-launched ballistic missiles.

Further innovation in miniaturizing warheads was accomplished by the mids, when versions of the Teller—Ulam design were created that could fit ten or more warheads on the end of a small MIRVed missile see the section on the W88 below.

The Soviet thermonuclear weapons program was aided heavily by Klaus Fuchs. The idea of a hydrogen bomb arose from discussions between Enrico Fermi and Edward Teller in From Teller lectured at Los Alamos on what he called the "super".

This information was important to the Soviets, but not solely for the information about the US bomb project.

The importance of this material was in that it confirmed that the United States were working on their own thermonuclear weapon research.

Tritium is an isotope of hydrogen with two neutrons, which allows for more efficient fusion reactions to occur during the detonation of a nuclear weapon.

Discovering the properties of this radioactive material would allow the Soviet Union to develop a more powerful weapon that requires less fuel.

Following Fuchs's return, experts from the Soviet Union spent a great deal of time researching his findings for themselves.

Even though the Soviets did obtain some original ideas, the findings of this research served to confirm Fuchs's notes from the American lectures on the matter.

After his return to England in mid, Fuchs was not again in touch with Soviet intelligence until September , when his controller confirmed the Soviet interest in thermonuclear weapons.

In response Fuchs provided details of the "ongoing theoretical superbomb studies in the U. Under this act, Fuchs did not have routine access to American collaborators like Fermi and Teller.

Fuchs was very close to Teller at Los Alamos, and while there Fuchs had worked on thermonuclear weapons.

As Teller later recalled, "he [Fuchs] talked with me and others frequently in depth about our intensive efforts… it was easy and pleasant to discuss my work with him.

He also made impressive contributions, and I learned many technical facts from him. In February the Soviet Union formally began its hydrogen bomb program.

A month later Fuchs again met with Feklisov, an event which "played an exceptional role in the subsequent course of the Soviet thermonuclear bomb program.

The first Soviet fusion design, developed by Andrei Sakharov and Vitaly Ginzburg in before the Soviets had a working fission bomb , was dubbed the Sloika , after a Russian layer cake , and was not of the Teller—Ulam configuration.

It used alternating layers of fissile material and lithium deuteride fusion fuel spiked with tritium this was later dubbed Sakharov's "First Idea".

Though nuclear fusion might have been technically achievable, it did not have the scaling property of a "staged" weapon.

Thus, such a design could not produce thermonuclear weapons whose explosive yields could be made arbitrarily large unlike U.

The fusion layer wrapped around the fission core could only moderately multiply the fission energy modern Teller—Ulam designs can multiply it fold.

Additionally, the whole fusion stage had to be imploded by conventional explosives, along with the fission core, substantially multiplying the amount of chemical explosives needed.

Attempts to use a Sloika design to achieve megaton-range results proved unfeasible. After the United States tested the " Ivy Mike " thermonuclear device in November , proving that a multimegaton bomb could be created, the Soviets searched for an additional design.

The "Second Idea", as Sakharov referred to it in his memoirs, was a previous proposal by Ginzburg in November to use lithium deuteride in the bomb, which would, in the course of being bombarded by neutrons, produce tritium and free deuterium.

The next breakthrough was discovered and developed by Sakharov and Yakov Zel'dovich , that of using the X-rays from the fission bomb to compress the secondary before fusion "radiation implosion" , in early It was the largest nuclear weapon developed and tested by any country.

In work began at Aldermaston to develop the British fusion bomb, with Sir William Penney in charge of the project.

British knowledge on how to make a thermonuclear fusion bomb was rudimentary, and at the time the United States was not exchanging any nuclear knowledge because of the Atomic Energy Act of However, the British were allowed to observe the U.

Castle tests and used sampling aircraft in the mushroom clouds , providing them with clear, direct evidence of the compression produced in the secondary stages by radiation implosion.

Because of these difficulties, in British prime minister Anthony Eden agreed to a secret plan, whereby if the Aldermaston scientists failed or were greatly delayed in developing the fusion bomb, it would be replaced by an extremely large fission bomb.

In the Operation Grapple tests were carried out. The first test, Green Granite was a prototype fusion bomb, but failed to produce equivalent yields compared to the U.

The second test Orange Herald was the modified fission bomb and produced kilotons—making it the largest fission explosion ever. At the time almost everyone including the pilots of the plane that dropped it thought that this was a fusion bomb.

This bomb was put into service in A second prototype fusion bomb Purple Granite was used in the third test, but only produced approximately kilotons.

A second set of tests was scheduled, with testing recommencing in September The first test was based on a "… new simpler design. A two stage thermonuclear bomb that had a much more powerful trigger".

On April 28, a bomb was dropped that yielded 3 megatons—Britain's most powerful test. Two final air burst tests on September 2 and September 11, , dropped smaller bombs that yielded around 1 megaton each.

American observers had been invited to these kinds of tests. After Britain's successful detonation of a megaton-range device and thus demonstrating a practical understanding of the Teller—Ulam design "secret" , the United States agreed to exchange some of its nuclear designs with the United Kingdom, leading to the US—UK Mutual Defence Agreement.

Instead of continuing with its own design, the British were given access to the design of the smaller American Mk 28 warhead and were able to manufacture copies.

British access to nuclear weapons information was cut-off by the United States at one point due to concerns about Soviet espionage.

Full cooperation was not reestablished until an agreement governing the handling of secret information and other issues was signed.

The People's Republic of China detonated its first hydrogen thermonuclear bomb on June 17, , 32 months after detonating its first fission weapon, with a yield of 3.

A story in The New York Times by William Broad [35] reported that in , a supposed Chinese double agent delivered information indicating that China knew secret details of the U.

W88 warhead, supposedly through espionage. France 's journey in building nuclear weapons began prior to World War II in The development of nuclear weapons was slowed during the country's German invasion.

The United States did not want France to acquire expert knowledge about nuclear weaponry, which ultimately led to the Alsos Mission.

The missions followed closely behind the advancing forward-front to obtain information about how close Germany was to building an atomic weapon.

Following the surrender of the Nazis, Germany was divided into "zones of occupation". The "zone" given to the French was suspected to contain several nuclear research facilities.

The United States conducted Operation Harborage to seize any and all information about nuclear weaponry from the French.

The Operation strategized to have American troops intercede advancing French army, allowing the Americans to seize any German scientists or records as well as destroy the remaining functional facilities.

However it was not until that a tangible goal of building plutonium reactors progressed. Two years later, a reactor was being built and a plutonium separating plant began construction shortly after.

In the question about continuing to explore building an atomic bomb was raised. Ultimately, the Prime Minister decided to continue efforts developing an atomic bomb in secret.

In late , tasks were delegated between the CEA and Defense Ministry to propel atomic development such as finding a test site, providing the necessary uranium, and physical device assembly.

Charles de Gaulle returned to power and was elected France's Fifth Republic's first president in De Gaulle, a strong believer in the nuclear weapons program, approved the country's first nuclear test to take place in one of the early months of It was called " Gerboise Bleue ", translating to "Blue jerboa ".

The bomb used a plutonium implosion design with a yield of 70 kilotons. The French nuclear testing site was moved to the unpopulated French atolls in the Pacific Ocean.

The first test conducted at these new sites was the "Canopus" test in the Fangataufa atoll in French Polynesia on 24 August , the country's first multistage thermonuclear weapon test.

The bomb was detonated from a balloon at a height of metres. The result of this test was significant atmospheric contamination.

France reportedly had great difficulty with its initial development of the Teller-Ulam design, but it later overcame these, and is believed to have nuclear weapons equal in sophistication to the other major nuclear powers.

France and China did not sign or ratify the Partial Nuclear Test Ban Treaty of , which banned nuclear test explosions in the atmosphere, underwater, or in outer space.

Between and France carried out more than nuclear tests. France signed the Comprehensive Nuclear-Test-Ban Treaty that same year, and then ratified the Treaty within two years.

France confirmed that its nuclear arsenal contains about warheads, carried by submarine-launched ballistic missiles SLBMs and fighter-bombers in France has four Triomphant-class ballistic missile submarines.

One ballistic missile submarine is deployed in the deep ocean, but a total of three must be in operational use at all times. The three older submarines are armed with 16 M45 missiles.

The newest submarine, "Le Terrible" , was commissioned in , and it has M51 missiles capable of carrying TN 75 thermonuclear warheads.

The air fleet is four squadrons at four different bases. In total, there are 23 Mirage N aircraft and 20 Rafales capable of carrying nuclear warheads.

France's nuclear program has been carefully designed to ensure that these weapons remain usable decades into the future. On May 11, , India announced that it had detonated a thermonuclear bomb in its Operation Shakti tests "Shakti-I", specifically.

Samar Mubarakmand , a Pakistani nuclear physicist, asserted that if Shakti-I had been a thermonuclear test, the device had failed to fire.

Harold M. Agnew , former director of the Los Alamos National Laboratory , said that India's assertion of having detonated a staged thermonuclear bomb was believable.

Rajagopal Chidambaram , former chairman of the Atomic Energy Commission of India said that India has the capability to build thermonuclear bombs of any yield at will.

The yield of India's hydrogen bomb test remains highly debatable among the Indian science community and the international scholars.

In an interview in August , the director for the test site preparations, Dr. Santhanam claimed that the yield of the thermonuclear explosion was lower than expected and that India should therefore not rush into signing the CTBT.

Other Indian scientists involved in the test have disputed Dr. Santhanam's claim, [51] arguing that Santhanam's claims are unscientific.

India officially maintains that it can build thermonuclear weapons of various yields up to around kilotons on the basis of the Shakti-1 thermonuclear test.

Israel is alleged to possess thermonuclear weapons of the Teller—Ulam design, [54] but it is not known to have tested any nuclear devices, although it is widely speculated that the Vela Incident of may have been a joint Israeli—South African nuclear test.

It is well established that Edward Teller advised and guided the Israeli establishment on general nuclear matters for some twenty years.

Congress , after receiving credible information from an "American scientist" Teller , on Israel's nuclear capability.

North Korea claimed to have tested its miniaturised thermonuclear bomb on 6 January North Korea's first three nuclear tests , and were relatively low yield and do not appear to have been of a thermonuclear weapon design.

In , the South Korean Defense Ministry speculated that North Korea may be trying to develop a "hydrogen bomb" and such a device may be North Korea's next weapons test.

These seismic recordings cast doubt upon North Korea's claim that a hydrogen bomb was tested and suggest it was a non-fusion nuclear test.

On 3 September , the country's state media reported that a hydrogen bomb test was conducted which resulted in "perfect success".

According to the U. Intelligence released an early assessment that the yield estimate was kilotons, [66] with an uncertainty range of 70 to kilotons.

Its yield estimate was revised to kilotons, while noting the estimate had some uncertainty and an undisclosed margin of error.

The Teller—Ulam design was for many years considered one of the top nuclear secrets, and even today it is not discussed in any detail by official publications with origins "behind the fence" of classification.

United States Department of Energy DOE policy has been, and continues to be, that they do not acknowledge when "leaks" occur, because doing so would acknowledge the accuracy of the supposed leaked information.

Aside from images of the warhead casing, most information in the public domain about this design is relegated to a few terse statements by the DOE and the work of a few individual investigators.

In the United States government declassified a document stating "[I]n thermonuclear TN weapons, a fission 'primary' is used to trigger a TN reaction in thermonuclear fuel referred to as a 'secondary'", and in added, "[I]n thermonuclear weapons, radiation from a fission explosive can be contained and used to transfer energy to compress and ignite a physically separate component containing thermonuclear fuel.

Whether these statements vindicate some or all of the models presented above is up for interpretation, and official U. Other information, such as the types of fuel used in some of the early weapons, has been declassified, though precise technical information has not been.

Most of the current ideas on the workings of the Teller—Ulam design came into public awareness after the Department of Energy DOE attempted to censor a magazine article by U.

In , Morland had decided that discovering and exposing this "last remaining secret" would focus attention onto the arms race and allow citizens to feel empowered to question official statements on the importance of nuclear weapons and nuclear secrecy.

Morland eventually concluded that the "secret" was that the primary and secondary were kept separate and that radiation pressure from the primary compressed the secondary before igniting it.

When an early draft of the article, to be published in The Progressive magazine, was sent to the DOE after falling into the hands of a professor who was opposed to Morland's goal, the DOE requested that the article not be published, and pressed for a temporary injunction.

The DOE argued that Morland's information was 1 likely derived from classified sources, 2 if not derived from classified sources, itself counted as "secret" information under the " born secret " clause of the Atomic Energy Act , and 3 was dangerous and would encourage nuclear proliferation.

Morland and his lawyers disagreed on all points, but the injunction was granted, as the judge in the case felt that it was safer to grant the injunction and allow Morland, et al.

The Progressive Through a variety of more complicated circumstances, the DOE case began to wane as it became clear that some of the data they were attempting to claim as "secret" had been published in a students' encyclopedia a few years earlier.

After another H-bomb speculator, Chuck Hansen , had his own ideas about the "secret" quite different from Morland's published in a Wisconsin newspaper, the DOE claimed that The Progressive case was moot, dropped its suit, and allowed the magazine to publish its article, which it did in November Morland had by then, however, changed his opinion of how the bomb worked, suggesting that a foam medium the polystyrene rather than radiation pressure was used to compress the secondary , and that in the secondary there was a spark plug of fissile material as well.

He published these changes, based in part on the proceedings of the appeals trial, as a short erratum in The Progressive a month later.

Morland's work is interpreted as being at least partially correct because the DOE had sought to censor it, one of the few times they violated their usual approach of not acknowledging "secret" material that had been released; however, to what degree it lacks information, or has incorrect information, is not known with any confidence.

The difficulty that a number of nations had in developing the Teller—Ulam design even when they apparently understood the design, such as with the United Kingdom , makes it somewhat unlikely that this simple information alone is what provides the ability to manufacture thermonuclear weapons.

Nevertheless, the ideas put forward by Morland in have been the basis for all the current speculation on the Teller—Ulam design.

In January , Soviet leader Mikhail Gorbachev publicly proposed a three-stage program for abolishing the world's nuclear weapons by the end of the 20th century.

Sakharov —89 was recruited into the Soviet Union's nuclear weapons program in , a year after he completed his doctorate. In the US detected the first Soviet test of a fission bomb, and the two countries embarked on a desperate race to design a thermonuclear hydrogen bomb that was a thousand times more powerful.

Like his US counterparts, Sakharov justified his H-bomb work by pointing to the danger of the other country's achieving a monopoly.

But also like some of the US scientists who had worked on the Manhattan Project, he felt a responsibility to inform his nation's leadership and then the world about the dangers from nuclear weapons.

Self-publishing was the method at the time for spreading unapproved manuscripts in the Soviet Union. Many readers would create multiple copies by typing with multiple sheets of paper interleaved with carbon paper.

After the essay was published, Sakharov was barred from returning to work in the nuclear weapons program and took a research position in Moscow.

More than a year and a half later, he persuaded the Politburo, the party's executive committee, to allow Sakharov and Bonner to return to Moscow.

Sakharov was elected as an opposition member to the Soviet Congress of People's Deputies in Later that year he had a cardiac arrhythmia and died in his apartment.

He left behind a draft of a new Soviet constitution that emphasized democracy and human rights. On 5 February , during a training mission flown by a B , a Mark 15 nuclear bomb , also known as the Tybee Bomb , was lost off the coast of Tybee Island near Savannah, Georgia.

The bomb was thought by the Department of Energy to lie buried under several feet of silt at the bottom of Wassaw Sound.

The conventional explosives in two of the Mk28 -type hydrogen bombs detonated upon impact with the ground, dispersing plutonium over nearby farms.

In his book Dark Sun: The Making of the Hydrogen Bomb , author Richard Rhodes describes in detail the internal components of the " Ivy Mike " Sausage device, based on information obtained from extensive interviews with the scientists and engineers who assembled it.

According to Rhodes, the actual mechanism for the compression of the secondary was a combination of the radiation pressure, foam plasma pressure, and tamper-pusher ablation theories described above; the radiation from the primary heated the polyethylene foam lining the casing to a plasma, which then re-radiated radiation into the secondary's pusher, causing its surface to ablate and driving it inwards, compressing the secondary, igniting the sparkplug, and causing the fusion reaction.

The general applicability of this principle is unclear. W88 nuclear warhead, a small MIRVed warhead used on the Trident II SLBM , had a prolate egg or watermelon shaped primary code-named Komodo and a spherical secondary code-named Cursa inside a specially shaped radiation case known as the "peanut" for its shape.

The reentry cones for the W88 and W87 are the same size, 1. Putting the secondary, which is heavier than the primary, in the wider part of the cone allows it to be larger, but it also moves the center of mass aft , potentially causing aerodynamic stability problems during reentry.

To make the primary small enough to fit into the narrow part of the cone, its bulky insensitive high explosive charges must be replaced with more compact "non-insensitive" high explosives that are more hazardous to handle.

The W88 also contains tritium , which has a half life of only From Wikipedia, the free encyclopedia. This section needs additional citations for verification.

Foam plasma mechanism firing sequence. Warhead before firing; primary fission bomb at top, secondary fusion fuel at bottom, all suspended in polystyrene foam.

High-explosive fires in primary, compressing plutonium core into supercriticality and beginning a fission reaction.

Fission primary emits X-rays that are scattered along the inside of the casing, irradiating the polystyrene foam. Polystyrene foam becomes plasma, compressing secondary, and plutonium sparkplug begins to fission.

Compressed and heated, lithium-6 deuteride fuel produces tritium and begins the fusion reaction. The neutron flux produced causes the U tamper to fission.

A fireball starts to form. Warhead before firing. The nested spheres at the top are the fission primary; the cylinders below are the fusion secondary device.

Fission primary's explosives have detonated and collapsed the primary's fissile pit. The primary's fission reaction has run to completion, and the primary is now at several million degrees and radiating gamma and hard X-rays, heating up the inside of the hohlraum and the shield and secondary's tamper.

The primary's reaction is over and it has expanded. The surface of the pusher for the secondary is now so hot that it is also ablating or expanding away, pushing the rest of the secondary tamper, fusion fuel, and fissile spark plug inwards.

The spark plug starts to fission. Not depicted: the radiation case is also ablating and expanding outwards omitted for clarity of diagram.

The reporting of doses in terms of absorbed energy in units of Gy and rad rather than the use of the biologically significant, biologically weighted Sievert , in both the SMR and cognitive performance data is typical.

Many other investigations into cognitive outcomes, such as Schizophrenia as a result of prenatal exposure, have been conducted with "no statistically significant linear relationship seen", there is a suggestion that in the most extremely exposed, those who survived within a kilometer or so of the hypocenters, a trend emerges akin to that seen in SMR, though the sample size is too small to determine with any significance.

The Japanese government has recognized about , people as hibakusha. As of March 31, [update] , , were still alive, mostly in Japan.

Updated annually on the anniversaries of the bombings, as of August [update] , the memorials record the names of more than , hibakusha ; , in Hiroshima [] and , in Nagasaki.

If they discuss their background, Hibakusha and their children were and still are victims of fear based discrimination and exclusion when it comes to prospects of marriage or work [] due to public ignorance about the consequences of radiation sickness or that the low doses that the majority received were less than a routine diagnostic x-ray , much of the public however persist with the belief that the Hibakusha carry some hereditary or even contagious disease.

Perhaps as many as people from Hiroshima sought refuge in Nagasaki. He was seriously burnt on his left side and spent the night in Hiroshima.

He arrived at his home city of Nagasaki on August 8, the day before the bombing, and he was exposed to residual radiation while searching for his relatives.

He was the first officially recognized survivor of both bombings. During the war, Japan brought as many as , Korean conscripts to Japan to work as forced labor.

Most issues were eventually addressed in through lawsuits. Hiroshima was subsequently struck by Typhoon Ida on September 17, More than half the bridges were destroyed, and the roads and railroads were damaged, further devastating the city.

It provided financial assistance for reconstruction, along with land donated that was previously owned by the national government and used for military purposes.

Hiroshima Prefectural Industrial Promotion Hall, the closest surviving building to the location of the bomb's detonation, was designated the Hiroshima Peace Memorial.

Nagasaki was also rebuilt after the war, but was dramatically changed in the process. The pace of reconstruction was initially slow, and the first simple emergency dwellings were not provided until The focus on redevelopment was the replacement of war industries with foreign trade, shipbuilding and fishing.

New structures were also raised as memorials, such as the Nagasaki Atomic Bomb Museum , which was opened in the mids.

The role of the bombings in Japan's surrender , and the ethical, legal, and military controversies surrounding the United States' justification for them have been the subject of scholarly and popular debate.

Japanese historian Tsuyoshi Hasegawa argued that the entry of the Soviet Union into the war against Japan "played a much greater role than the atomic bombs in inducing Japan to surrender because it dashed any hope that Japan could terminate the war through Moscow's mediation".

Although not accepted by mainstream historians, this became the position in Japanese school history textbooks.

Those who oppose the bombings give other reasons for their view, among them: a belief that atomic bombing is fundamentally immoral, that the bombings counted as war crimes , and that they constituted state terrorism.

Like the way it began, the manner in which World War II ended cast a long shadow over international relations for decades to come.

By June 30, , there were components for only nine atomic bombs in the US arsenal, all Fat Man devices identical to the one used in the bombing of Nagasaki.

There were also many improvements to their performance that had been suggested or recommended, but that had not been possible under the pressure of wartime development.

Leahy had decried the use of the atomic bombs as adopting "an ethical standard common to the barbarians of the Dark Ages", [] but in October , he reported a military requirement for bombs.

The American monopoly on nuclear weapons lasted only four years before the Soviet Union detonated an atomic bomb in September By , the United States had 23, nuclear weapons, while the Soviet Union had 40, By , nine nations had nuclear weapons , [] but Japan was not one of them.

American nuclear weapons were stored on Okinawa, and sometimes in Japan itself, albeit in contravention of agreements between the two nations.
