In January 1950 president Truman made the decision to continue the research and development of thermonuclear weapons. He wrote a letter to Crawford H. Greenewalt asking him to take charge of overseeing the designs, construction, and operation of the new site to produce plutonium. They set up distant sites across the country and ended up having operations in 32 states.…
The soviet espionage stole information that helped soviet scientists speed up the development of their atomic program. In this paper you will learn about the Soviet espionage and the Manhattan project. With that said, the Manhattan Project was started from the threat of the Axis Powers having an atomic bomb. Their scientists would be able to make their first bomb after a breakthrough of a Nuclear Chain Reaction. Countries trying to get information for America and the Manhattan project failed and the U.S. caught them.…
During World War II the United States government propelled a $2 billion venture. This venture, known as the Manhattan Project, was a push to deliver a nuclear bomb. This venture was gone up against by gathering nuclear researchers from everywhere throughout the world. President Truman's choice to drop the atomic bomb on the urban areas of Hiroshima and Nagasaki were the immediate reason for the finish of World War II in the Pacific.…
This was a far-reaching program as, “Over the next several years, the program’s scientists worked on producing the key materials for nuclear fission–uranium-235 and plutonium. They sent them to Los Alamos, New Mexico, where a team led by J. Robert Oppenheimer worked to turn these materials into a workable atomic bomb” (History.com). The scientists and manufacturers were determined to produce a functionable nuclear bomb. In addition, “Thousands of hours of research and development as well as billions of dollars had contributed to its production” (NPS Editor). This illustrates the monumental amount of money and labor which was invested into this immense project.…
A secret military project files for the Manhattan Project: started in 1942. The production of the first Untied States nuclear weapon, was built during World War II. This product triggered the beginning of the Manhattan Project. A great population located in New York, feared of Nazi soldiers and what was about to come of them.…
The Use of the Atomic Bomb The Manhattan Project was a secretive project created by the government to get ahead in the push for a nuclear bomb. After its completion, the atomic bomb was secretly tested in the New Mexico desert. The bomb was a success and next came the hardest decision of Harry S. Truman’s life. He was president at the time and he had to decide whether or not the bomb should be dropped.…
The world’s greatest physicists and mathematicians took part in commanding the efforts during World War II, the project was projected to cost a heaping $20 billion due to the production of the first uranium and plutonium bombs. Albert Einstein influenced the beginning of the Manhattan Project. In collaboration with Leo Szilard, Einstein wrote a letter to President Franklin D. Roosevelt in 1939, to inform him of possible German nuclear weapons research and proposing that the United States began its own research into atomic energy. The American quest for nuclear explosives was driven by the fear of Germany’s very own Adolf Hitler and the fact that he would invent and gain military advantage. This project took a little less four years, the first atomic bombs were designed and built at a site in Los Alamos, New Mexico. The Manhattan Project produces three bombs: the first bomb known as “Gadget” and was used as a test model. Due to the enormous expense and slow production rates for explosive material, no further tests were conducted. The second bomb, known as “Little Boy” was detonated over the city of Hiroshima in August 6, 1945 during World War II, and the final bomb, “Fat Man” was detonated over the city of Nagasaki three days later. Which led to Emperor Hirohito to announce his country’s surrender. Nuclear facilities were built at Oak Ridge, Tennessee and Hanford, Washington. The main assembly plant was built at Los Alamos, New Mexico. The reason it was named the Manhattan Project was to trick enemy countries into thinking any development would be taking place in Manhattan, New York. The government was taking a chance to take enemy fire or possible bombing of an innocent state. This was made to believe that there was some sort of project taking place in a location that had nothing to do with…
The Manhattan Project was one of the largest endeavors conducted by the United States. Today, it is a well known piece of history, but at the time the Manhattan Project was completed confidentially. The Manhattan Project employed thousands of civilians, and spent billions of dollars (adjusted for inflation) in secrecy. Approximately 200,000 people died as a result of the Manhattan Project and it is widely debated whether the bombing of Japanese cities with atomic bombs was necessary. Because the Manhattan Project was the cause of such significant scientific and engineering feats, as well as because it resulted in one of the most controversial decisions of all time, it is important to study the Manhattan Project thoroughly.…
The Manhattan Project was a secret project that was kept from public knowledge and even the vice president didn’t even know about the project until the completion of the project was nearly done. The Manhattan Project has hundreds of scientists and was based out of numerous locations spread through out the country and there were many testing sights but the most common testing sight was the one that was located in a desert in New Mexico and it was the Trinity Test Tower where they would test the effectiveness of the bombs that they made during the Manhattan Project.…
Multiple meetings were held and numerous copies of General L. R. Groves memorandum, which detailed the event, were sent to important figures in the discussion of the atomic bomb. The decision to drop the bomb was not a hasty one- planning began before May of 1945. Seventy accredited individuals in the field of atomic study were educated enough about the prospect of the event that they could send a petition to President Truman supporting the use of the bomb. Due to the planning the adjudged the potential damage of the bomb, the power of this new weapon was understood before its use against Japan. Truman’s statement that “it was the most terrible thing ever discovered” is proof of that.…
The Manhattan Project was developed to give America their best chance at not only fighting but winning a nuclear war. When German physicists had the knowledge to split a uranium atom, fear ensured. The world scientific community held the concern of Nazi scientists utilizing this new found energy to build a nuclear bomb. As to avoid this, the United States implemented their own project. With the input of multiple scientists, and the ultimate approval of President Roosevelt, the first atomic bomb began to be designed and built by the United States.…
Hiroshima is a city located in Japan, an island in Asia off the mainland of China. On December 7th, 1941 the Japanese launched an attack on the United States by bombing Pearl Harbor. This attack caused the United States to enter World War II and declare war on Japan and its counterparts Germany and Italy. The war was long and devastating for both sides both Allies and Axis powers. After a long and strained war the Japanese have been pushed back to their homeland. The United States had two options, one invade the island of Japan or use the atomic bomb they were developing. On August 9th, 1945 the United States bombed the Japanese city Hiroshima killing thousand Japanese civilians making them finally surrender the war.…
Truman became president of the United States. Truman ended up being the President that made the decision to use the atomic bombs named Fat Man and Little Boy on Japan. It was not any easy decision. There were several factors which helped Truman determine his use of the bombs. First was the loss of lives if Americans were to invade mainland Japan. It was estimated more lives would be lost in that fighting then by dropping the bombs. The lives Truman were mostly concerned about was American lives (Jones, 2008). Keeping Russia out of the Pacific theatre was another factor. Truman did not like communism and did not want Russia to have any influence over Asia or Japan (Jones, 2008). By dropping the bombs, this did not allow Russia to mobilize in time to aid in the Pacific fighting. Justification for the money spent on developing them was another factor (pcf.city.hiroshima.jp, n.d.). Using the bombs could justify their production. Finally, Japan never agreed to surrender unconditionally. Japan was given plenty of time to surrender before the first bomb was dropped in Hiroshima on August 6, 1945. After that bomb was dropped, they were given another opportunity, but did not. On the 9th of August the second bomb was dropped on Nagasaki. On August 14, 1945 Japan finally surrendered…

In 1945, the United States of America dropped two atomic bombs on the cities of Hiroshima and Nagasaki in Japan. On August 6, the nuclear weapon “Little Boy” was dropped on Hiroshima because it was a city of considerable military importance and contained Japan's Second Army Headquarters. It also was the communications centre and storage depot. On August 9, at 11:02 a.m., at an altitude of 1,650 feet, Fat Man (right) exploded over Nagasaki. The yield of the explosion was later estimated at 21 kilotons, 40 percent greater than that of the Hiroshima bomb.…
