Manhattan Project History

The Manhattan Project was the American program for researching and developing the first atomic bombs. The weapons produced were based solely upon the principles of nuclear fission of uranium 235 and plutonium 239, The project as a whole cost approximately 2 billion dollars of taxpayer’s money and employed over 120,000 people . It was a massive undertaking to say the least. A project of this size needed justification and it seemingly came in the form of attacking the Japanese . The President's chief of staff Admiral Leahy The democrats would have suffered a political death blow if they were not able to justify the investment.

Others argue that the bombing of Hiroshima was uncalled for. They say that it was morally wrong, and that Japan was weakened and not able to win the war anyway. Many may also think that Japan truly wanted peace after what they did. I disagree with these opinions

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.

1. The bombings killed 129,000-246,000 people in total over two to four months. The Japanese army managed to kill over 300,000 people in a single city over a span of just over a month. People really shouldn't be calling the bombings truculent when Japan's allies, the nazis, started the Holocaust and committed genocide .2. The US even gave Japan a chance to surrender before the bombs were dropped by issuing the Potsdam declaration which stated that if they didn’t surrender, Japan would face “prompt and utter destruction”. Japan did not surrender so they had to face the consequence. The US could have just dropped the bombs without any warning, but they decided to give Japan a chance to surrender first. This shows that the US were not inhumane in the bombings of Hiroshima and

The Manhattan Project was one of the most notorious and catastrophic projects in United State history. A bomb that took years to perfect and made the U.S. gamble millions of dollars on new technology that wasn't certain to work. All the secretive facilities scattered all over the U.S. contributed to the creation of a futuristic weapon of mass destruction beyond anyone’s imagination. The atomic bomb caused thousands to die and left years of remnant radiations. The Manhattan Project will forever remain as one of the greatest “successful” catastrophic discoveries in human history.

It became known that the German knew how to create an atomic bomb and FDR created a committee to study and create atomic bombs, named the Manhattan Project.The Manhattan Project was significant to the war because it led to the end of World War II and caused the Japanese to surrender to the Americans. The amount of people working together along with the cost and time which led to advancements in technology that was far ahead of any enemy. The creation of the bombs delivered a push in the advancement of science, innovation, designing, military and the entire of society into another age. It drew out the powerhouse that we consider today to be the United States of

World War II lasted for six years from September,1 1939 to September 2, 1945 and resulted with Japan's surrender but believe it or not many events occurred both good and bad before anyone could make that choice. Before the declaration of this war japan had made an agreement with the U.S in which they gave them a friendship medal signifying peace. Turns out that wasn't the case japan actually backstabbed the U.S and on the morning of December 7th, 1941 the japanese attacked Pearl Harbor destroying nearly 20 American ships and more than 300 airplanes. About 2,403 sailors, soldiers and civilians were killed and about 1,000 people were wounded. After that the U.S could no longer trust Japan for many reasons they decided to fight back with two atomic bombs on Japan. The dropping of these two bombs on that country in my personal opinion is not justified. My reasons are that this was the first time the U.S was going to try these bombs out so in other words this was an experiment in which they had no clue the amount of damage that

The United States should not have dropped the atomic bomb because it was unnecessary. United State still had many other resources to use on Japan to end the war. They should not have used this powerful atomic bomb because Japan was already defeated. When the United States wanted to stop World War II, they could have used not too powerful bombs at a location which would not

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.

They shouldn’t have used bombs on Japan because of course those bombs had killed many innocent people that didn’t deserve it. It was cruel to do the same just for revenge. Those bombs that were used on Japan had taken innocent lives of people who lived within the areas that the people

On August 6, 1945, the United States of America dropped an atomic bomb on Hiroshima, Japan. For decades, there have been feuds relating to the justification of the bombing. Was the U.S justified? It depends on your opinion. The United States was justified due to the unprovoked attack and bombing of Pearl Harbor, Hawaii, which occurred three years prior to the bombing of Hiroshima, it was necessary to stop the war because it saved thousands of American lives. Until then, the fight had never been on United States soil. Innocent men, women and children did not have to worry about being killed on their land until the infamous day: December 7, 1941, the attack of Pearl Harbor. On that day, the Japanese took to the skies with 423 planes, arriving in Pearl Harbor, killing a total of 2,403 and wounding 1178. Hitting 18 U.S ships, it crippled the U.S naval fleet in one day. Little known to the people, the bombing also destroyed 180 fighter jets used in the U.S Air Force. This was an unjustified, barbaric act and dropping the bomb on Hiroshima was justified.

On the 6th and 9th of August, 1945, the United States of America dropped the Atomic Bombs on the Japanese cities of Hiroshima and Nagasaki. The use of these bombs brought a quick end to World War 2, yet caused extensive damage to the two Japanese cities. There have often been disputes as to whether the USA was justified in the dropping of the atomic bombs because of the damage they caused, not only to the cities, but to the people of Japan as well. Many people believe that the USA should not have dropped the bombs because of the damage they caused, and they also claim that Japan was already defeated. However, Japan did not surrender, and prolonging the war was not an option for America, as it believed it would cause even more casualties, not only to American troops, but to Japan as well. Thus the USA was justified in dropping the bombs on Japan.

Finally, the bombing of Hiroshima and Nagasaki was unjustified because of the lack of testing. Although the project to design the first atomic bomb, codenamed the Manhattan Project, began in 1941, the first bomb was not ready to be tested until the month before it would be used in 1945. When it was tested at Trinity Site in New Mexico, the detonation caused unexpected results (“The Manhattan Project”). It caused “A blinding flash visible for 200 miles lit up the morning sky. A mushroom cloud reached 40,000 feet, blowing out windows of civilian homes up to 100 miles away. When the cloud returned to earth it created a half-mile wide crater metamorphosing sand into glass” (“The

On August 6, 1945 uranium gun-type atomic bomb (Little Boy) was dropped on Hiroshima, within the first day of the bombings the effects killed 90,000–166,000 people in Hiroshima. The effects of the atomic bomb left many dead, homeless, and sacred. Even four months later people would die from radiation poisoning and discovering they had cancer now. Skin would be peeling off like bark on trees, this was a true horrifying sight. The United States were at war with japan but, does that justify what they did? Some would say what they did was inhuman and just plan wrong. They say there were other alternatives that the United Sates could have done. I believe there could have been a better way of ending the war with japan but I understand why the United States did what they did. The Japanese came out of nowhere and attacked the United States did they think that the US would just roll over and die? The should of known not to surprise attack one of the strongest nations. The needed to be put back in place and show the rest of the world that the US was one not to be reckon with.

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.
