How To Build The Atomic Bomb Research Essay

515 Words3 Pages

The atomic bomb development started when German chemists Otto Hahn and Fritz Strassmann discovered nuclear fission in 1938. It began with a theoretical explanation by Lise Meitner and Otto Frisch that gave hope to the development of an atomic bomb. America bore fears that this discovery and theories would allow the Germans to develop atomic weapons before the Americans did, especially amongst scientists who were refugees (expressed in the Einstein-Szilard letter).
In the late 1939, the United states then prompted a preliminary research. However, progress was sluggish till late 1941, when there was the arrival of the British MAUD Committee report. Initially, tons of un-enriched uranium and a neutron moderator (e.g. heavy water) were required for the manufacturing of the bomb. However, they presented ground breaking findings and found that only 5–10 kilograms of isotopically enriched …show more content…

These were headed by Major General Leslie R. Groves, Jr., whose position in the U.S. Army Corps of Engineers was to design and build the atomic bombs. He then appointed J. Robert Oppenheimer who aided in the organization and direction of the project in Los Alamos Laboratory in New Mexico where the bomb was designed.

Eventually, two types of bombs were developed - Little Boy and Fat Man (named by Robert Serber). Little boy was a gun-type weapon whose development was overseen by Lieutenant Commander Francis Birch's group of Captain William S. Parsons's Ordnance (O) Division at the Manhattan Project's Los Alamos Laboratory. Fat Man was a implosion-type nuclear weapon which was more complicated, more powerful and efficient. Even though the Japanese also had a nuclear weapon research undergoing, it lacked resources in every aspect of the Manhattan Project resulting in stagnated progress in the development of an atomic

After Pearl Harbor, Japan won many battles, but their success would end after the Battle of Midway when Japan had been destroyed beyond repair. So, as the United States kept fighting smaller islands to get to Japan's main island, it got very hard so they decided to use their secret weapon, the atomic bomb. A project, known as the Manhattan project, was creating a bomb so powerful it could wipe out cities. So, the United States used the “ Fat Man “ on Nagasaki, and the “ Little Boy “ on Hiroshima. The atomic bomb was a success and killed about 145,000 people in both cities.

September, 1942 was the date that Groves was appointed head of this experiment. The main reason of this was because of his previous work at creating camps, depots, air bases, munitions plants, hospitals, airplane plants, and the massive Pentagon. Groves was a leader The Fat man and Little boy changed the world today, how we fight and what we use, the nukes opened a whole new generation of chemical warfare. In addition, The Bombs took a few years to complete with the help of many scientist. He was a fighter and lead america to victory.

In 1938 two German scientists discovered how to split a uranium atom, which led to the creation of the atomic bomb. The U.S. used an international team of scientists, many of whom were Germans who had left their country because of the Nazis, to turn this discovery into a bomb. This was known as the Manhattan Project. They created three bombs and the first was tested successfully on July 16, 1945 in the New Mexico desert.

These bombs have only been tested before and never used in a real war situation until the bombing of Hiroshima and Nagasaki. “Little boy” was dropped on August 6, 1945 on Hiroshima by the B-29 Superfortress named Enola Gay(John Hersey). “Fat man” was dropped three days after “Little boy” on Nagasaki by another B-29 Superfortress named Bockscar(John Hersey). The United States reasons for dropping the atomic bombs are because they wanted to limit American casualties from future battles, they wanted to establish dominance over the war before Russia could, and they wanted to use the first atomic bomb in a real war situation(Jennifer Rosenburg). They wanted to drop the bomb as fast as they could while still planning it out well.

World War II seemed close to an end in May of 1945 and Japan was not down yet, and still fighting. America faced a hard decision: how to send the war against Japan as quickly as possible and with the least casualties possible. Since 1939, America had been working on the Manhattan Project, a project aiming to create nuclear bombs. A single bomb could destroy an entire city and America yielded that power against Japan. Using incendiary bombs, 67 entire sections of Japanese cities were burnt out.

It's not the bomb that kills people, it's people that kill people. Congress should allow the group of scientists to develop and test this new weapon because the atomic bomb helped the U.S. defeat Japan, stop World War II, and prevent future wars. One of the primary reasons for the utilization of the atomic bomb was to bring an end to the war in Japan as quickly as possible.

The bombing of Pearl Harbor convinced Roosevelt that more had to be done on the atomic research. By the end of 1942, bomb research had become bomb production, Manhattan Project was ran by the military with Major Leslie Groves as officer in charge. Bomb production was carried out in three locations, Oak Ridge Tennessee handled production of the bomb fuel U-235, Hanford Washington handled production of plutonium fuel, and Los Alamos New Mexico handled bomb production and assembly. These three locations became huge cities due to size of and manpower required for this project. Once the project was at a larger scale the work in factories and producing the atomic weapons employed over 130,000 people.

In 1939 a group of U.S scientists became concerned with nuclear weaponry research being conducted in Nazi Germany, in 1940 The U.S government began funding its own atomic weapons development program. Over the next several years the program’s scientists worked on producing the key materials for nuclear fission (uranium-239 and plutonium [Pu-239]). They were sent to Los Alamos, New Mexico, where a team worked to turn these materials into a workable atomic bomb. On July 16, 1945, The Manhattan Project held it’s first successful test of an atomic device at the Trinity test site at New Mexico, by this time The Allies had already defeated Germany in Europe. Japan vowed to fight to the end in the Pacific, despite clear indication (1944) that there was no chance of winning.
