British and US scientists concentrated on fission of U-235 which would lead to a new element of mass U-239 an atomic number of 94 in which would lead them to discover neptunium #93 and plutonium #94 which was based off the finding of the uranium element (“Outline History of Nuclear Energy” 1). Harnessing energy from this was the main intention in 1945 (“Outline History of Nuclear Energy” 1). The atomic bomb development most focused on through 1939 to 1945. The Manhattan Project was the creation and testing of the first atomic bomb, 1942-1945 (“Nuclear History Timeline” 1). The first atomic device was successfully tested in New Mexico on July 16, 1945 (“Outline History of Nuclear Energy” 1).
But first the energy must be released; it can be released from atoms in two ways, which are nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined together to form a larger atom an example would be the sun produces energy. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. The Atomic weapons haven’t poped to life, however they have a long history before them. This long history goes back to 1933 when Leo Szilárd realizes the concept of the nuclear chain reaction.
According to Merriam-Webster, nuclear fission is defined as “the splitting of an atomic nucleus resulting in the release of large amounts of energy” (Nuclear Fission). In the book Remembering the Manhattan Project: Perspectives on the Making of the Atomic Bomb and Its Legacy, Richard Rhodes, an American journalist and historian, states that fission was essentially discovered by accident. On December 21, 1938, German physicists, Otto Hahn and Fritz Strassman, were performing an experiment in which they bombarded uranium atoms with neutrons (Rhodes 17). They saw that this procedure created mutated atoms that had strange characteristics. Hahn and Strassman found that the neutrons split the nuclei of the uranium in half producing radioactive barium and krypton (Rhodes 18).
Soon after the first bomb test, atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki in 1945. The first hydrogen bomb was developed by a team of United States scientists and was first tested on November 1, 1952. After World War II, a new age of military strategy occurred. The United States built up massive nuclear weapons arsenals and developed highly sophisticated systems of delivery and defense. Today's intercontinental ballistic missiles (ICBMs) carry one or more multiple, independently targeted reentry vehicles (MIBVs), each with its own nuclear war head.
The U.S. government gace priority to perfecting and stockpiling atomic bombs, and scientists discovered that initiating a fusion reaction was mmore tehn somply placing a container of hydrogen near a fusion trigger. Tension to develop the hydrogen bomb increased in the United States after the Sovier Union set off ites first atomic bomb in August 1949. The military, the joint congressional committee on atomic energy, and several noted physicists, including Edward Teller and Ernest Lawrence, called for creation of a so-called super-bomb, but the general advisory of the Atomic Energy Commission (AEC), Chaired by J. Robert Oppenheimer, in agreement recommended that the bomb should not be developed, because of the technical difficulties involved, the need to enlarge the atomic bomb reserve, and because of the moral considerations.

This method made it needless to produce expensive tritium in reactors and made it podddible to build fusion weapons that could fit into an airplane.
The Hydrogen Bomb Thesis Statement The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb, which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT. The Hydrogen Bomb The Atomic Bomb Was A Essential First Step toward the Development of the Hydrogen Bomb, Before the atomic bomb was developed by the united states during World War II, there was no way to produce the extreme amounts of heat needed to initiate the fusion reaction of the hydrogen bomb. Even after World War II, the hydrogen bomb faced many political and technical obstacles. The U.S. government gave priority to perfecting and stockpiling atomic bombs, and scientist discovered that initiating a fusion reaction was more than simply placing a container of hydrogen near a fission trigger.
On May 12, 1951 the first Thermonuclear Hydrogen bomb, or H-bomb, was tested in the United States; this bomb was so much stronger than the atomic bomb that research stopped soon after its invention (SV;SV). Soon the research shifted to submarine-launched ballistic missiles called SLBMs that were first tested in 1960 but were soon to be outclassed by a new, more advanced type of weapon (“Nuclear Warfare”).

Atomic Bomb On August 2, 1939 Albert Einstein wrote to President Franklin D. Roosevelt. This was right before the start of World War 2. In this letter Einstein and several other scientists told Roosevelt of the efforts Hitler was making to purify U-235 in which he hoped to make an atomic bomb. This is when the United States started the Manhattan Project. This was the project of making an atomic bomb.
Nuclear fuel goes through fission when struck by free neutrons and then generates neutrons when it breaks apart. Only U-235 uranium atoms, a nuclear fuel, could be used for the chain reaction. This was because it was able to be obtained in large enough quantities to even be useful. Little Boy was the codename of the atomic bomb dropped on Hiroshima. The design of Little Boy used the gun assembly method, by shooting one piece of the uranium into the other to create a chemical explosion.
