The Manhattan Project: The Destruction Of The Atomic Bomb

In August 1945, America dropped two Atomic bombs on Japan in the cities of Hiroshima and Nagasaki. The two bombings killed at least 130,000 people and were the first and last use of nuclear weapons in warfare.

This committee decided that the United States should retain nuclear superiority, in the event that international relations deteriorated following World War II (US Department of Energy). This decision is a foreshadowing of the Cold War, and nuclear arms race which followed the dropping of nuclear weapons on Japan. The interim committee also decreed that a regulatory system should be created to control the development of nuclear weapons, since other nations would inevitably obtain the technology needed to develop weapons. Possibly, the most influential decision made by the interim committee was to keep the details of the atomic bomb a secret, to maintain the shock effect, until after it had been dropped on Japan. Two atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki. The first bomb dropped was a uranium bomb, nick-named Little Boy, was untested before its detonation (US Department of Energy). The second, dropped after the Japanese did not surrender, was a plutonium bomb, nick-named Fat Man. The dropping of these bombs propelled the United States to a seat of world power, as they were the only country to obtain a weapon of mass destruction. The Manhattan Project became scientific and engineering feat, employing over 100,000 individuals. The exceptional organizational model the Manhattan Project provided, allowed for great scientific achievements in the later part of

Leading up to this time the fascist dictators began to gain power in European countries. The big three being the countries of Nazi Germany, Adolf Hitler, Italy, Benito Mussolini, and Japan, Emperor Hirohito. In 1935 Italy invades and conquers Ethiopia, shorty after Nazi Germany and Fascist Italy sign a treaty of cooperation. In 1937,Japan, lead by Hirohito, invaded China. Joseph Stalin, of Russia, signs the German-Russian non-aggression pact; which allowed Hitler to invade Poland. But when news of the German invasion of Poland spread Britain along with France joined the war to oppose the Germans. Germany only continues in it’s quest for conquest by invading Denmark and Norway in the year 1940. Meanwhile the United States is remaining completely uninvolved under it’s Neutrality Act that was passed in 1935. The United States, lead by president Franklin D. Roosevelt, enacted it’s Lend Lease Act in 1941 in order to trade and sell to allied forces, for payment after war. Japan realizes that the U.S. wasn’t exactly being neutral so it sent suicide bombers to attack our naval base in Pearl Harbor on December 7, 1941. Thus leading into the use of the atomic bomb, but first the construction, an event referred to as the Manhattan Project. The name Manhattan Project came about because the program began under the Manhattan Engineering District of the War Department.

“ The atom bomb was no ‘great decision.’ It was merely another powerful weapon in the arsenal of righteousness.” This quote was said by Harry S. Truman the first President who used an atomic bomb. The program that was able to create this monstrous power was known as the Manhattan Project. Creating this weapon was their main priority. The United States was in the midst of World War 2. The atomic bomb is considered to be the main factor that ended that war. It was a race against the multiple enemies of the United States, to be the first to acquire this power and use it when necessary. The Manhattan Project was kept strictly confidential and, created the foundation of the future and more powerful nuclear weapons to come.

With the new working bomb, during World War II American B-29 bomber dropped the world’s first atomic bomb called the little boy weighing 9,000 pounds on Hiroshima, Japan instantly killing eighty-thousand people then killing over tens of thousands of people after due to radiation exposure. Three days later another bomb

The United States dropped their first atomic bomb over the Japanese city of Hiroshima on August 6th, 1945. The explosion was tragic, “90 percent of the city was wiped out and immediately killed 80,000 people; tens and thousand more would later die to radiation exposure” (Lemay and Paul). Innocent children and citizens would die.

Thesis Statement: The Manhattan Project was the American program for researching and developing the first atomic bombs because of the project it cost a lot of people their lives.

In August of 1945, the world’s first atomic bomb was dropped on the city of Hiroshima in

The process of building the two atomic bombs was long and hard. The Manhattan project employed 120,000 people, and cost almost $2 billion. Although there were 120,000 Americans working on the project only a select group of scientist knew of the atomic bomb development. Vice president Truman never knew about the development of the bombs until he became president. The axis powers did not know what was going on with the development of the atomic bomb; there was a soviet spy in the project. The soviet spy was Klaus Fuchs, and he had become one of the few people who knew of the bombs.

The first true testing of the Atomic Bomb began on August 6, 1945 in Hiroshima, Japan. The Atomic Bomb was dropped by the Enola Gay which a was plane that was piloted by Colonel Paul W. Tibbets, Jr. The bomb was released from approximately 31,600 feet above Hiroshima. When the bomb made contact with the ground it immediately blew up, destroying about

The Manhattan Project was to see if making an atomic bomb possible. The success of this project would forever change the world forever making it known that something this powerful can be manmade. The Manhattan Project’s success was something that had an impact on everybody involved since they helped create something with so much destructive power it could destroy a city within seconds.

The Manhattan Project was a very important event throughout the World War II history. It began the development of the atomic bomb and other nuclear weapons that were of good help during the war. It first began with a German scientist separating the uranium atom, which made people be scared of what Hitler might be capable of. Also Hitler and his people had begun discovering new types of weapons that were useful for them in the war. Something that apparently Hitler did not quite think about, was the persecution of Jewish scientists such as Albert Einstein, who could very well use his abilities against Hitler.

On August 6th, 1945 the United States military dropped the first atomic bomb as an act of war on the Japanese city of Hiroshima. 3 days later, the second and last to date, atomic bomb was dropped onto Nagasaki, Japan. Under the direction of President Harry Truman, the atomic bombs were dropped in response to the disregarded ultimatum

What was the Manhattan Project, we know it created the first atomic bombs (see Fig. 1), but how did it end World War II and use fission to its full power? World War II and the Manhattan Project lasted from 1939 to 1945. World War II started when Hitler invaded Poland on September 1, 1939. The origins of the Manhattan Project date back to a letter Albert Einstein sent Franklin D. Roosevelt warning him of the powers of fission and the weapons it could produce. 60 million people were killed in World War II and the Manhattan Project resulted in the deaths of 130,000 Japanese civilians.

Starting in 1942, the United States Army, working with the American Government, created a top secret program named the Manhattan project. In present day 2015 it is still unclear if there was a specific motif that drove to the creation of the bomb. Nevertheless it can be speculated that the attacks on Pearl Harbor are largely attributed its creation. In essence, the Bomb (later named fat boy) had the capabilities to destroy an entire city and was only going to be used when completely necessary. Promptly enough, a conference was held in July of 1945 in Cecilienhof, Germany called the Potsdam Conference. The meeting involved the leaders of “The Three Powers” of USSR, Britain, and The United States who negotiated a “terms and conditions-like”
