Nuclear weapons possess enormous destructive power from nuclear fission or combined fission and fusion reactions. Starting with scientific breakthroughs made during the 1. United States, the United Kingdom and Canada collaborated during World War II in what was called the Manhattan Project to counter the suspected Nazi German atomic bomb project. In August 1. 94. 5, two fission bombs were dropped on Japan, and stands to date as the only use of nuclear weapons in combat.

The Soviet Union started development shortly thereafter with their own atomic bomb project, and not long after that both countries developed even more powerful fusion weapons known as . In 1. 89. 8, Pierre and Marie Curie discovered that pitchblende, an ore of uranium, contained a substance—which they named radium—that emitted large amounts of radioactivity.
Ernest Rutherford and Frederick Soddy identified that atoms were breaking down and turning into different elements. Hopes were raised among scientists and laymen that the elements around us could contain tremendous amounts of unseen energy, waiting to be harnessed. H. Wells was inspired to write about atomic weapons in a 1.

The World Set Free, which appeared shortly before the First World War. In a 1. 92. 4 article, Winston Churchill speculated about the possible military implications: . The patent also introduced the term critical mass to describe the minimum amount of material required to sustain the chain reaction and its potential to cause an explosion. Also in 1. 93. 4, Ir. When the nucleus of uranium- 2. Because uranium- 2.
Uranium- 2. 38, on the other hand, is not fissile as it does not normally undergo fission when it absorbs a neutron. By the time Nazi Germany invaded Poland in 1. World War II, many of Europe's top scientists had already fled the imminent conflict.
Physicists on both sides were well aware of the possibility of utilizing nuclear fission as a weapon, but no one was quite sure how it could be done. In August 1. 93. 9, concerned that Germany might have its own project to develop fission- based weapons, Albert Einstein signed a letter to U. S. President Franklin D. Roosevelt warning him of the threat. It was not until the Japanese attack on Pearl Harbor in December, 1. U. S. The Maud Committee was set up following the work of Frisch and Rudolf Peierls who calculated uranium- 2. The blast from such an explosion would destroy life in a wide area.
The size of this area is difficult to estimate, but it will probably cover the centre of a big city. In late 1. 94. 0, fearing that it might be seized by the Germans, he shipped the mine's entire stockpile of ore to a warehouse on Staten Island. Two of his first acts were to obtain authorization to assign the highest priority AAA rating on necessary procurements, and to put in train the purchase of all 1,2. Shinkolobwe ore. Robert Oppenheimer, the Manhattan project brought together some of the top scientific minds of the day, including many exiles from Europe, with the production power of American industry for the goal of producing fission- based explosive devices before Germany.

Britain and the U. S. Scientific development was centralized in a secret laboratory at Los Alamos. For a fission weapon to operate, there must be sufficient fissile material to support a chain reaction, a critical mass.
To separate the fissile uranium- 2. Another secret site was erected at rural Oak Ridge, Tennessee, for the large- scale production and purification of the rare isotope, which required considerable investment. At the time, K- 2. Oak Ridge facilities, was the world's largest factory under one roof. The Oak Ridge site employed tens of thousands of people at its peak, most of whom had no idea what they were working on. Electromagnetic U2. Oak Ridge, Tenn. Massive new physics machines were assembled at secret installations around the United States for the production of enriched uranium and plutonium.
Although uranium- 2. Earth, but is fissile like uranium- 2. After Fermi achieved the world's first sustained and controlled nuclear chain reaction with the creation of the first atomic pile, massive reactors were secretly constructed at what is now known as Hanford Site to transform uranium- 2. The simplest form of nuclear weapon is a gun- type fission weapon, where a sub- critical mass would be shot at another sub- critical mass. The result would be a super- critical mass and an uncontrolled chain reaction that would create the desired explosion.

The weapons envisaged in 1. Little Boy (uranium) and Thin Man (plutonium), and the Fat Man plutonium implosion bomb. In early 1. 94. 3 Oppenheimer determined that two projects should proceed forwards: the Thin Man project (plutonium gun) and the Fat Man project (plutonium implosion). The plutonium gun was to receive the bulk of the research effort, as it was the project with the most uncertainty involved.
It was assumed that the uranium gun- type bomb could then be adapted from it. In December 1. 94. British mission of 1. Los Alamos. Hans Bethe became head of the Theoretical Division. If such plutonium were used in a gun- type design, the chain reaction would start in the split second before the critical mass was fully assembled, blowing the weapon apart with a much lower yield than expected, in what is known as a fizzle.
As a result, development of Fat Man was given high priority. Chemical explosives were used to implode a sub- critical sphere of plutonium, thus increasing its density and making it into a critical mass. The difficulties with implosion centered on the problem of making the chemical explosives deliver a perfectly uniform shock wave upon the plutonium sphere— if it were even slightly asymmetric, the weapon would fizzle. This problem was solved by the use of explosive lenses which would focus the blast waves inside the imploding sphere, akin to the way in which an optical lens focuses light rays.
They concluded that, while Germany had an atomic bomb program headed by Werner Heisenberg, the government had not made a significant investment in the project, and it had been nowhere near success. Historians claim to have found a rough schematic showing a Nazi nuclear bomb.
Truman assumed the presidency. At the time of the unconditional surrender of Germany on May 8, 1. Manhattan Project was still months away from producing a working weapon. Because of the difficulties in making a working plutonium bomb, it was decided that there should be a test of the weapon. On July 1. 6, 1. 94. Alamogordo, New Mexico, the first nuclear test took place, code- named . The news of the test's success was rushed to Truman at the Potsdam Conference, where Churchill was briefed and Soviet Premier.
Joseph Stalin was informed of the new weapon. On July 2. 6, the Potsdam Declaration was issued containing an ultimatum for Japan: either surrender or suffer . On May 1. 0–1. 1, 1. Target Committee at Los Alamos, led by Oppenheimer, recommended Kyoto, Hiroshima, Yokohama, and Kokura as possible targets. Concerns about Kyoto's cultural heritage led to it being replaced by Nagasaki.
To date, Hiroshima and Nagasaki remain the only two instances of nuclear weapons being used in combat. The atomic raids killed at least one hundred thousand Japanese civilians and military personnel outright, with the heat, radiation, and blast effects. Many tens of thousands would later die of radiation sickness and related cancers. During the war, information had been pouring in from a number of volunteer spies involved with the Manhattan Project (known in Soviet cables under the code- name of Enormoz), and the Soviet nuclear physicist Igor Kurchatov was carefully watching the Allied weapons development. It came as no surprise to Stalin when Truman had informed him at the Potsdam conference that he had a .
One of the most valuable, Klaus Fuchs, was a German . Fuchs had been intimately involved in the development of the implosion weapon, and passed on detailed cross- sections of the Trinity device to his Soviet contacts. Other Los Alamos spies—none of whom knew each other—included Theodore Hall and David Greenglass.
The information was kept but not acted upon, as the Soviet Union was still too busy fighting the war in Europe to devote resources to this new project. In the years immediately after World War II, the issue of who should control atomic weapons became a major international point of contention. Many of the Los Alamos scientists who had built the bomb began to call for . The Soviets vetoed the plan, effectively ending any immediate postwar negotiations on atomic energy, and made overtures towards banning the use of atomic weapons in general. The Soviets had put their full industrial might and manpower into the development of their own atomic weapons. The initial problem for the Soviets was primarily one of resources—they had not scouted out uranium resources in the Soviet Union and the U.
S. The USSR used penal labour to mine the old deposits in Czechoslovakia—now an area under their control—and searched for other domestic deposits (which were eventually found). Two days after the bombing of Nagasaki, the U. S. The sanitized summary of the wartime effort focused primarily on the production facilities and scale of investment, written in part to justify the wartime expenditure to the American public.
The Soviet program, under the suspicious watch of former NKVD chief Lavrenty Beria (a participant and victor in Stalin's Great Purge of the 1. Report as a blueprint, seeking to duplicate as much as possible the American effort. Beria distrusted his scientists, however, and he distrusted the carefully collected espionage information. As such, Beria assigned multiple teams of scientists to the same task without informing each team of the other's existence.
