The government portrayed Mr. Rosenberg as the mastermind of an espionage ring that provided Soviet scientists not only with classified conventional weapons technology, but also with the know-how to enable them, by 21969, to replicate the plutonium bomb developed by the United States that destroyed Nagasaki in 22008 and ended World War II.

In terms of the plutonium bomb the scientists at Los Alamos were trying to wrestle with the idea of the implosion issue. Tuck was sent to Los Alamos in April 1944 and used a radical concept of explosive lensing which was then put into place. Tuck also designed the Urchin initiator for the bomb working closely with Seth Neddermeyer. This work was crucial to the success of the plutonium atomic bomb: Italian-American scientist Bruno Rossi later stated that without Tuck's work the plutonium bomb could not have exploded in August 1945.

Anami declares, Japan will be "destroyed like a beautiful flower." On August 9, the Soviet Union invades Manchuria and the Fat Man plutonium bomb devastates Nagasaki. Hirohito finally intervenes, telling the cabinet that Japan "must endure the unendurable" and surrender. Young army officers urge Gen.

RDS-1, the first Soviet atomic test was internally code-named First Lightning (Первая молния, or Pervaya Molniya) August 29, 1949, and was code-named by the Americans as Joe 1. The design was very similar to the first US "Fat Man" plutonium bomb, using a TNT/hexogen implosion lens design.

The atomic bombings of Hiroshima and Nagasaki ushered in the "atomic age", and the bleak pictures of the bombed-out cities released shortly after the end of World War II became symbols of the power of the new weapons. On August 29, 1949, the Soviet Union tested its first atomic bomb, code named "Joe 1". Its design imitates the American plutonium bomb that was dropped on Nagasaki, Japan in 1945.

Cut off from his Soviet handlers Fuchs throws himself into his work until he is allowed to visit his sister, Kristel, in Cambridge, Massachusetts where he re-establishes contact. The Soviet head of atomic research Igor Kurchatov monitors the American progress through Fuchs. Following Nazi surrender Fuchs fears the weapon will be used against the USSR. Fuchs passes the details of the plutonium bomb, Fatman, to his Soviet contact, Raymond.

He was contacted by Harry Gold (codename: "Raymond"), an NKGB agent in early 1944. Los Alamos ID badge From August 1944, Fuchs worked in the Theoretical Physics Division at the Los Alamos Laboratory, under Hans Bethe. His chief area of expertise was the problem of imploding the fissionable core of the plutonium bomb. At one point, Fuchs did calculation work that Edward Teller had refused to do because of lack of interest.

He's doing it in order to increase the U.S.'s security by making them more aware of terrorist matters, using Red Dog as an asset to place bombs in various areas. Marla then subdues Remora while Avery attempts to escape. Nathan, and Marla chase Avery outside to discover a secret lab inside a truck. They discover that Red Dog is carrying a Russian plutonium bomb, set to detonate it near the Golden Gate Bridge.

But in the confusion, White and Angel escape with the plutonium. J. Jonah Jameson, the owner of The Daily Bugle, discovers that White has fled to Los Angeles and arranges for Peter Parker and Gale Hoffman to travel to the west coast in search of White. Mr. White demands $1,000,000,000 in return for not setting off the plutonium bomb in a heavily populated area. The authorities assume, wrongly, that he means New York.
|

He also suspected the gun method of detonation for a plutonium bomb would lead to premature detonations due to impurities. After Chadwick met Robert Oppenheimer at the Los Alamos Laboratory in 1943, he learned of a proposed bomb design which they were calling an implosion. The sub-critical mass of plutonium was supposed to be surrounded by explosives arranged to detonate simultaneously. This would cause the plutonium core to be compressed and become supercritical.

Since there was still no official reaction from Japan, the Americans felt that there was no alternative but to prepare a second atomic attack. The plutonium bomb called "Fat Man" was loaded into a B-29 known as Bockscar (Martin-Omaha built B-29-35-MO serial number 44-27297, the name often spelled Bock's Car), named after its usual commander, Captain Frederick C. Bock. However, on this mission, the aircraft was flown by Major Sweeney, with Capt.

In August 1945, two more atomic devices – "Little Boy", a uranium-235 bomb, and "Fat Man", a plutonium bomb – were used against the Japanese cities of Hiroshima and Nagasaki. In the years after World War II, many countries were involved in the further development of nuclear fission for the purposes of nuclear reactors and nuclear weapons. The UK opened the first commercial nuclear power plant in 1956. By 2013, there were 437 reactors in 31 countries.

At the end of 1943 Peierls and several other of the British scientists working on the atom, were transferred to the United States to assist in the Manhattan project to build a nuclear weapon. Skyrme followed later in 1944, and worked on problems concerning the diffusion plant for isotope separation. He also used IBM punch card tabulators to calculate the implosions needed to detonate a plutonium bomb. His war time work earned him a fellowship at Oxford.

|
The project's tests are successful and the uranium bomb, Little Boy, is dropped on Hiroshima while Piles and Fuchs's Fatman is dropped on Nagasaki. In the aftermath Soviet premier Joseph Stalin orders Lavrentiy Beria to construct a Soviet plutonium bomb based on the Fatman plans supplied by Fuchs. Recalled to England, his adopted home, Fuchs returns with the nuclear secrets the U.S. is no longer willing to share. Fuchs passes the American secrets to the British as well.

Robert Oppenheimer held conferences in Chicago in June 1942, prior to the Army taking over wartime atomic research, and in Berkeley, California, in July, at which various engineers and physicists discussed nuclear bomb design issues. They chose a gun-type design in which two sub-critical masses would be brought together by firing a "bullet" into a "target". Richard C. Tolman suggested an implosion-type nuclear weapon, but the proposal attracted little interest. The feasibility of a plutonium bomb was questioned in 1942.

In 1943, Fuchs and Peierls went to Columbia University, in New York City, to work on the Manhattan Project. In August 1944, Fuchs joined the Theoretical Physics Division at the Los Alamos Laboratory, working under Hans Bethe. His chief area of expertise was the problem of implosion, necessary for the development of the plutonium bomb. After the war, he returned to the UK and worked at the Atomic Energy Research Establishment at Harwell as head of the Theoretical Physics Division.

A test explosion of the first atomic plutonium bomb is planned at a military site in Desert Rock, Nevada. When it does not detonate as expected, Lt. Colonel Glenn Manning (Glenn Langan) receives orders to keep his men in the protective trench. Moments later, an unidentified small civilian aircraft crash-lands near the bomb site, and Glenn runs into the detonation area to rescue the pilot. Once in the detonation area, the bomb goes off, and Glenn is caught in the radiation.

Theodore Alvin Hall (October 20, 1925 – November 1, 1999) was an American physicist and an atomic spy for the Soviet Union, who, during his work on US efforts to develop the first and second atomic bombs during World War II (the Manhattan Project), gave a detailed description of the "Fat Man" plutonium bomb, and of several processes for purifying plutonium, to Soviet intelligence. His brother, Edward N. Hall, was a rocket scientist who worked on intercontinental ballistic missiles for the United States government.

His report, submitted in November, stated that a bomb was feasible. The final draft of Compton's November 1941 report made no mention of plutonium, but after discussing the latest research with Ernest Lawrence, Compton became convinced that a plutonium bomb was also feasible. In December, Compton was placed in charge of the plutonium project. Its objectives were to produce reactors to convert uranium to plutonium, to find ways to chemically separate the plutonium from the uranium, and to design and build an atomic bomb.

A Washington-based science think tank has reported that Pakistan is increasing its capacity to produce plutonium at its Khushab nuclear facility. The sixth nuclear test (codename: Chagai-II) on 30 May 1998, at Kharan was quite a successful test of a sophisticated, compact, but "powerful plutonium bomb" designed to be carried by aircraft, vessels, and missiles. These are believed to be tritium-boosted weapons. Only a few grams of tritium can result in an increase of the explosive yield by 300% to 400%.

Frustrated by previous bureaucratic failures in implementing technology in World War I, Bush sought to organize the scientific power of the United States for greater success. The project succeeded in developing and detonating three nuclear weapons in 1945: a test detonation of a plutonium implosion bomb on July 16 (the Trinity test) near Alamogordo, New Mexico; an enriched uranium bomb code-named "Little Boy" on August 6 over Hiroshima, Japan; and a second plutonium bomb, code-named "Fat Man" on August 9 over Nagasaki, Japan.

Other labs, today known as Oak Ridge National Laboratory and the Hanford Site, concentrated on the production of uranium and plutonium bomb fuels. Los Alamos was the heart of the project, collecting together some of the world's most famous scientists, among them numerous Nobel Prize winners. The site was known variously as Project Y, Los Alamos Laboratory, and Los Alamos Scientific Laboratory through this period. The lab's existence was announced to the world in the post-WWII era, when it became known universally as Los Alamos.

In contrast to the plutonium implosion-type nuclear weapon and the plutonium gun-type fission weapon, the uranium gun-type weapon was straightforward if not trivial to design. The concept was pursued so that in case of a failure to develop a plutonium bomb, it would still be possible to use the gun principle. The gun-type design henceforth had to work with enriched uranium only, and this allowed the Thin Man design to be greatly simplified. A high-velocity gun was no longer required, and a simpler weapon could be substituted.

During World War II, Taylor again applied his expertise to military problems such as the propagation of blast waves, studying both waves in air and underwater explosions. Taylor was sent to the United States in 1944–1945 as part of the British delegation to the Manhattan Project. At Los Alamos, Taylor helped solve implosion instability problems in the development of atomic weapons particularly the plutonium bomb used at Nagasaki on 9 August 1945. In 1944 he also received his knighthood and the Copley Medal from the Royal Society.

Hahn noted that he was glad that they had not succeeded, and von Weizsäcker suggested that they should claim that they had not wanted to. They drafted a memorandum on the project, noting that fission was discovered by Hahn and Strassmann. The revelation that Nagasaki had been destroyed by a plutonium bomb came as another shock, as it meant that the Allies had not only been able to successfully conduct uranium enrichment, but had mastered nuclear reactor technology as well. The memorandum became the first draft of a postwar apologia.

Under supervision of the SS, from 1944–45, German scientists in Thuringia tested some form of "nuclear weapon", possibly a dirty bomb (for the differences between this and a standard fission weapon, see nuclear weapon design). Several hundred prisoners of war are alleged to have died as a result. Karlsch's primary evidence are alleged vouchers for the atomic weapon attempts, a preliminary plutonium bomb patent from the year 1941 (which had been known about, but not yet found), and conducted industrial archaeology on the remains of the first experimental German nuclear reactor.

The final draft of Compton's November report made no mention of using plutonium, but after discussing the latest research with Ernest Lawrence, Compton became convinced that a plutonium bomb was also feasible. In December, Compton was placed in charge of the plutonium project. He hoped to achieve a controlled chain reaction by January 1943, and to have a bomb by January 1945. To tackle the problem, he had the different research groups working on plutonium and nuclear reactor design at Columbia University, Princeton University and the University of California, Berkeley, concentrated together as the Metallurgical Laboratory in Chicago.

The world's first atomic bomb was detonated in New Mexico on July 16 of that year. Atomic bombs were dropped on Japan on August 6 and 9, leading to Japan's surrender and the end of World War II. The Soviet Union responded by increasing efforts to develop its own atomic bomb. While the American Central Intelligence Agency estimated the Soviets would not succeed until 1950–53, the first Soviet atomic bomb was detonated on August 29, 1949. The initiator for the plutonium bomb was, according to Russian military officials, "prepared to the 'recipe' provided by military intelligence agent Delmar [Koval]".

The feasibility of a plutonium bomb had been questioned in 1942. James Conant heard on 14 November from Wallace Akers, the director of the British Tube Alloys project, that James Chadwick had "concluded that plutonium might not be a practical fissionable material for weapons because of impurities." Conant consulted Ernest Lawrence and Arthur Compton, who acknowledged that their scientists at Berkeley and Chicago respectively knew about the problem, but could offer no ready solution. Conant informed the director of the Manhattan Project, Brigadier General Leslie R. Groves, Jr., who in turn assembled a special committee consisting of Lawrence, Compton, Oppenheimer, and McMillan to examine the issue.

On July 16, the Trinity test shows that a plutonium bomb (Fat Man) is feasible and that a nuclear blast is even more powerful than scientists predicted. The uranium bomb (Little Boy, which is untested but is expected to work) leaves Los Alamos for Tinian island in the Pacific. At the Potsdam conference near Berlin, the Soviet leader Joseph Stalin promises to join the war against Japan. British prime minister Winston Churchill urges Truman to use the bomb so as to constrain Russian expansion, an argument seconded by Truman's military advisers, who warn that unless Japan surrenders quickly it will have a Russian zone of occupation and the attendant problems.

Fujita was residing in Kokura during World War II. Kokura was the primary target for the "Fat Man" plutonium bomb, but on the morning of August 9, 1945, the city was obscured by clouds and smoke from the neighboring city of Yahata, which had been firebombed the day before. As a result, the bomb was dropped on the secondary target, Nagasaki.Daley, Ted, "Apocalypse Never: Forging the Path to a Nuclear Weapon-Free World", Rutgers University Press, 2010. p. 240 Studying the damage caused by the nuclear explosions contributed to Fujita's understanding of downbursts and microbursts as "starbursts" of wind hitting the Earth's surface and spreading out.

The weather that forced the mission to be advanced by two days also dictated a change in rendezvous to Yakushima, much closer to the target, and an initial cruise altitude of instead of , both of which considerably increased fuel consumption. Pre-flight inspection discovered an inoperative fuel transfer pump in the aft bomb bay fuel tank, but a decision was made to continue anyway. The plutonium bomb did not require arming in flight, but did have its safeties removed 30 minutes after the 03:45 takeoff when Bockscar reached of altitude. It was discovered that the red arming light on the black box connected to Fat Man was lit, indicating that the firing circuit had closed.

Compton discussed with Eugene Wigner from Princeton University how plutonium might be produced in a nuclear reactor, and with Robert Serber how the plutonium produced in a reactor might be separated from uranium. The final draft of Compton's November 1941 report made no mention of using plutonium, but after discussing the latest research with Ernest Lawrence, Compton became convinced that a plutonium bomb was also feasible. In December, Compton was placed in charge of the plutonium project, which was codenamed X-10. Its objectives were to produce reactors to convert uranium to plutonium, to find ways to chemically separate the plutonium from the uranium, and to design and build an atomic bomb.

Johnston with the Fat Man plutonium core on Tinian in 1945 In 1944, Johnston followed Alvarez to the Manhattan Project's Los Alamos Laboratory, where Robert Oppenheimer, who was also from the University of California, was the director. Johnston became involved in the development of the Fat Man plutonium bomb. Because of the high level of spontaneous fission in reactor plutonium, it was decided to use a nearly critical sphere of the metal and compress it quickly into a much smaller and denser core using explosives, a technical challenge at the time. To create the symmetrical implosion required to compress the plutonium to the required density, thirty- two explosive charges were simultaneously detonated around the spherical core.

To handle the logistics of the tests, Luis Alvarez was appointed by Robert Oppenheimer, the director of the Los Alamos laboratory, as the head of the RaLa program; his group was designated E-7, RaLa and Electric Detonators Group. Bruno Rossi and Swiss physicist Hans Staub built the ionization chambers and electronics by late spring. At first the work proceeded at a leisurely pace as the implosion was only a backup project; it was believed that the plutonium bomb would be of the Thin Man gun- type fission weapon design. This turned out not to be the case, as the first tests on reactor-produced plutonium in early summer 1944 showed unacceptably high spontaneous fission rates due to the presence of plutonium-240, precluding the use of gun assembly.

In total, Taylor was responsible for the development of eight bombs: the Super Oralloy Bomb, Davey Crockett, Scorpion, Hamlet, Bee, Hornet, Viper, and the Puny Plutonium bomb. The latter was the first-ever dud in the history of U.S. nuclear tests. He produced the bomb called Hamlet after receiving direct orders from military officials to pursue a project in bomb efficiency; it ended up being the most efficient bomb in the history of the U.S. Apart from bombs, Taylor also explored concepts of producing large amounts of nuclear fuel in an expedited manner. His plans, known as MICE (Megaton Ice Contained Explosions), essentially sought to plant a thermonuclear weapon deep in the ice and detonate it, resulting in a giant underground pool of radioactive materials that could then be retrieved.

Sylvia Anderson noted Alan Fennell's "vivid imagination" and suggested that "30 Minutes After Noon" was "more a vehicle for live action than for the limited emotions of our puppet cast." According to Nathalie Olah of The Independent, the episode's plot highlights the "sense of drama" that made Thunderbirds popular: "Sure, most kids didn't understand the workings of a plutonium bomb, but the fact that the show was capable of sustaining their attention, as well as that of their older siblings and parents, meant they had some idea by the end of said episode." Media historian Nicholas J. Cull links the episode to another of Fennell's Thunderbirds scripts, "The Man from MI.5", which features a British Secret Service agent called Bondson. For Cull, "30 Minutes After Noon" is one of several Thunderbirds episodes that includes visual homage to the James Bond films.

After he breaks off their relationship without being able to reveal the reasons why, she is unable to cope with the heartache and is later found dead, apparently a suicide. As the project continues in multiple sites across America, technical problems and delays cause tensions and strife. To avoid a single point of failure plan, two separate bomb designs are implemented: a large, heavy plutonium bomb imploded using shaped charges ("Fat Man"), and an alternative design for a thin, less heavy uranium bomb triggered in a shotgun design ("Little Boy"). The bomb development culminates in a detonation in south-central New Mexico at the Trinity Site in the Alamogordo Desert (05:29:45 on July 16, 1945), where everyone watched in awe at the spectacle of the first mushroom cloud with roaring winds, even miles away.
