Hiroshima and Nagasaki Atomic Bombings

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

Part of the city was virtually leveled by the time the dust had settled. Thousands more people died months and years after from injuries and radiation poisoning. The second atomic bomb was dropped on Nagasaki, Japan just 3 days later on August 9th, 1945. The original target for the second bomb, codenamed "fat man", was the city kokura but the target was obscured by clouds over it. This time, over 3.5 square miles of the city was destroyed and over 60,000 people were killed instantly. Also like last time, thousands more people died years after from injuries and radiation poisoning. These two bombs brought about the end of WW2, but they also brought the beginning of the nuclear arms race.

“ 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

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.

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 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 origins of the Manhattan Project go back to 1939, when Hungarian-born physicist Leo Szilard, who had moved to the U.S. in 1938 to conduct research at Columbia University, became convinced of the feasibility of using nuclear chain reactions to create new, powerful bombs. German scientists had just conducted a successful nuclear fission experiment, and based on those results, Szilard was able to demonstrate that uranium was capable of producing a nuclear chain reaction. Szilard noted that Germany

In 1942, the Manhattan project was started. The Manhattan project was created to make the first nuclear weapon in the United States.The bomb was created to help defend the United States. World War II was going on and the United States was not involved yet. President Harry S. Truman was elected after the death of Franklin Delano Roosevelt. Harry

The Manhattan Project was the code name of the America’s attempt to construct an atomic bomb during World War II. It was named after the Manhattan Engineer District of the U.S. Army Corps of Engineers, because a lot of it’s earlier research was done in New York City. An atomic bomb is a weapon that uses the energy from a nuclear reaction called Fission for its destruction.

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

The project was completed first by the Americans on July 16 1945. The project’s name was The Manhattan Project. The project employed over 120,000 Americans to make one atomic bomb. Albert Einstein and Enrico Fermi wrote a letter advising the president to get into the race for the first

Then in 1943, the allies started gaining momentum against the japanese. Even though Japan was nearing defeat at the end of 1994, the Japanese had proved that they would do anything to win the war, including suicide tactics. Furthermore, America was planning on an invasian that would be even bloodier than that of D-Day and would possibly extend the war by two more years and kill even up to a million more lives on both sides. The US decided that building an atomic bomb was probably better than risking the deaths of more Americans and Japanese. Once the bomb was finished, they made plans to drop the bomb, which they code-named, Little Boy, on a city called Hiroshima. Hiroshima, had a population of 350,000 people, and was a location of a military base at the time of 1945. This made it a good location to target in hopes of achieving the goal to drive Japan out of the war. They used a plane called the Enola Gay, to drop the bomb they created, which they Code Named, Little Boy. By this point, Germany had already surrendered, which made Japan one of the last and primary targets for world war

Through the efforts of the “Manhattan Project” and the scientists within it, several nuclear bombs were created. Two of which, “Little Boy” and “Fat Man,” ended up being dropped on Japan. “Little Boy,” the only uranium bomb created was dropped on Hiroshima on August 6, 1945 (Batchelder 99-105). “Fat Man,” the second nuclear bomb ever used in warfare, detonated above Nagasaki on August 11, 1945 (Batchelder 95-105). The leaders of the United States, decided that dropping the newly developed atomic bombs on Japan was the smartest action they could take at the time, given the current situation that the United States and the world was in. Dropping the bombs on Japan was mainly motivated by the belief that human lives could be saved. A massive invasion of the Japanese mainland was the only other option if no bombs were going to be dropped. The fact that the Japanese main army of approximately two million had never before been defeated on top of the Japanese terrain which was much better suited for guerrilla warfare than the mechanical ways of the U.S. put estimated American deaths alone well over the deaths at Hiroshima and Nagasaki combined (Batchelder 114-118).

On August 6, 1945, during World War II an American B-29 bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima. Three days later, a second B-29 dropped another A-bomb on Nagasaki, killing an estimated 40,000 people. Japan’s Emperor
