The Manhattan Project: Japan's Massive Atomic Bomb

On the morning of August 6, 1945, a B-29 bomber named Enola Gay flew over the industrial city of Hiroshima, Japan and dropped the first atomic bomb ever. The city went up in flames caused by the immense power equal to about 20,000 tons of TNT. The project was a success. They were an unprecedented assemblage of civilian, and military scientific brain power-brilliant, intense, and young, the people that helped develop the bomb. Unknowingly they came to an isolated mountain setting, known as Los Alamos, New Mexico, to design and build the bomb that would end World War 2, but begin serious controversies concerning its sheer power and destruction. I became interested in this topic because of my interest in science and history. It seemed an

Was it necessary for Truman to drop the Atomic Bombs on Japan in World War II? On August 6, 1945, the first atomic bomb was dropped by a US aircraft on Hiroshima. This atomic bomb was dropped to force Japan into surrender, this bomb alone destroyed Hiroshima and over 90,000 people were instantly killed in the explosion and an additional 100,000 people perished from burns and radiation sickness. On August 9, 1945 only three days later, the second atomic bomb was dropped over Nagasaki resulting in an additional 80,000 casualties of the Japanese population. The people of Japan surrendered on August 14, 1945 soon after the bombing of Hiroshima and Nagasaki. Many people opposed to the use of the atomic bombs because people argued that Truman 's decision to use atomic bombs was a barbaric act of cruelty. People also argued that the US government had other ulterior motives to drop the atomic bomb that were necessary for America 's ideals. Necessary motives like presenting The Soviet Union a strong message for the Soviets to watch their step around America. A conventional way of warfare for Japan 's surrender would have costed many more American lives. Truman and others believed that the atomic bomb was necessary to save American lives but also Japanese lives. These actions from President Truman marked the end of the most destructive war in history.

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.

Hiroshima-Nagasaki bombs tragically slaughtered 140,000 people. The miniscule town boasts one of the highest per capita incomes in the United States, and is almost 80 percent white. The Manhattan Project decades hence burgeoned into Los Alamos National Laboratories (LANL) a massive facility, easily 27,000 acres embedded in a New Mexico mountain plateau. When population estimations include farmers, farming communities, and Native Americans, some 38,000 Americans lived within a closer radius than Amarillo, Texas. Work at nuclear facilities was egregiously health hazardous throughout the 1950s and 1960s, leading Congress to pair the Radiation Compensation Exposure Act (1990) with an Energy Employees Occupational Illness Compensation Act in 2000.

The Manhattan Project was a research and development project that produced the first nuclear weapons during World War II. The Manhattan project was the invention of the first two nuclear bombs, Fat man and little boy. These two bombs were dropped on Japanese islands to end World War II.

The first point of view to understand is the militaristic decision. How exactly did the bomb affect the War? It is in no question that the use of the atomic bombs ended World War II, their effect was paramount in the surrender of the Japanese Imperial Army. There were other plans suggested before using the atomic bomb. An invasion of Japan after soviet entry was also a choice for the United States. The United States had other choices but none would be as efficient and safe as the choice to use the bombs. After consideration the invasion of Japan was deemed impractical in terms of the loss of human lives. (Truman, Harry S) Another alternative to using the bomb was to choose less populated targets. Hiroshima was chosen as the first target due to its size and because it hasn’t been bombed

The atomic policy against Japan was closely related to the fear of Soviet expansion in Asia. U.S. leaders were strongly conscious of Russia’s agreement at Yalta to join the war against Japan three months past Germany’s surrender on May 7, 1945 (Fogelman, 124). Among the U.S. invasion of Japan planned for November 1, 1945, U.S. officials were doubtful about the cooperative mission with Russia in which Russia would have power at the peace table. However, the successful detonation at Alamogordo had transformed everything. The bomb guaranteed that the U.S. no longer required Russian aid to win in the Pacific (Wainstock, 132).

The Manhattan Project was a way for America to defend themselves and grow as a country. At the start of World War II Germany was already winning the race to building an atomic bomb. They had all of the supplies and people to do it. America was very concerned about this threat from Germany. When president Franklin D. Roosevelt got a letter from Albert Einstein starting we needed to start a nuclear program (Ratnesar 1).

The Manhattan Project was one, if not the most, secretive projects to take place in the history of the United States of America. Dating back to World War II, its purpose was to create a bomb capable of splitting atoms apart. The project was a success and resulted in one of the most devastating bombs ever to be developed and utilized by mankind. Franklin Delano Roosevelt and Harry S. Truman, the acting Presidents during the time, faced many factors that were involved in deciding to proceed with developing and ultimately, dropping the bomb.

The Manhattan Project was a code name for the atomic bomb. They did not want anyone to know about it because if they would have said, the atomic bomb everybody who knew about it would freak out. There were two types of atomic bombs in World War Two. The two types were the Fat Man and Little Boy. The Fat Man got its name because it was round and fat. The Fat man was used on Nagasaki. The Little Boy was called that because it was long and skinny. The Little Boy was dropped on Hiroshima. They were both dropped on a country called Japan.

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.

The Manhattan Project was a project led by the United States Government. The objective was to create a nuclear bomb for the ongoing war. Canada made the project possible by suppling uranium. The project began when scientists around the world realized German physicists discovered a way to split a uranium atom in 1939. Once scientists realized this discovery was capable of causing severe damage, the fear grew of Nazi's using it to their advantage. Albert Einstein and other scientists including Enrico Fermi decided that they should notify the American government. At first President Roosevelt didn't agree with the information provided in the letter by Albert Einstein. Butin 1941 the U.S government determined they should start an Atomic research

However, the projected losses were over 1 million, which was a staggering number. Meanwhile, America had been working on something in top secret. Project Manhattan was a top secret program created by the U.S. in 1939 after learning that Germany was also working on a similar project. The goal of the program was to design and construct a bomb. Over the next 6 years, scientists worked on creating the essential materials for nuclear fission–uranium-235 and plutonium (Pu-239). On July 16, 1945, the Manhattan Project held its first successful test of an atomic device at a test site in New

During WWII there were many different countries trying to develop nuclear weapons. The countries that were trying to develop them, wanted them because they wanted to the first nuclear superpower in the world. If any of these other countries ‘d developed them before the U.S. did, the way we live in today’s world would’ve been completely different than what we know it as.

In 1941, The United States began an atomic bomb program called the “Manhattan Project.” The main objective of the “Manhattan Project” was to research and build an atomic bomb before Germany could create and use one against the allied forces during World War II. German scientists had started a similar research program four years before the United States began so the scientists of the “Manhattan Project” felt a sense of urgency throughout their work (Wood “Men … Project”).
