The Manhattan Project And The Manhattan Project

The Manhattan Project had various short and long term affects around the world. Primarily, the research done to create an atomic bomb led to the discovery of how to harness nuclear power which affects our lives to this day. However, the Manhattan Project also led to the creation of two more atomic bombs which would be used in WWII, radiation poisoning resulting in the death of many , fear of nuclear weapons during the Cold War, the end of the Second World War which was still taking place in Japan, and the threat of nuclear weapons around the world that still exists.

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.

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

They came, unwarned. On the 7th of December 1941, the Japanese executed a full-fledged attack on Pearl Harbor. They mercilessly created havoc, with attacks that caused the sinking of eighteen American ships, as well as 170 aircrafts. The casualties were dreadful, with 1,177 of those lost lives had been of the crewmen. The very next day, President Roosevelt declared war on Japan, and thus the United States’ involvement of World War II. Americans of every state were absolutely enraged and bent on their will for vengeance against the Asian country. Within the shadows of galvanized America, Robert Oppenheimer had set his infamous Manhattan Project into action. This project was so disclosed that only a limited number of men truly knew of its purpose. The clandestine project held prior securities to the point in which famous scientists had to use codenames in order to visit Los Alamos, even wives were kept in the dark, and only key scientists could bring their wives along with them. (Source D) This project had been the discreet creation of the Atomic Bombs. Time and time again, this topic had never really dissipated, its controversial who, what and whys prompting generations to debate its palpable purpose. Was the aim really focused for the “good of all?” Was it for America’s self-preservation and wish to promptly put an end to all of the suffering? Many Americans to this day still believe and argue for the usefulness of the atomic bombings, that the droppings were justified.

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.

“We believe that . . . an early unannounced attack against Japan inadvisable. If the United States were to be the first to release this new means of indiscriminate destruction upon mankind, she would sacrifice public support throughout the world, precipitate the race for armaments, and prejudice the possibility of reaching an international agreement on the future control of such weapons. Much more favorable conditions could be created if nuclear bombs were first revealed to the world by a demonstration in an appropriately selected uninhabited area.” The initial test for the atomic bomb was dropped in Alamogordo, Mexico with experts observing more than 20 miles away. The explosion was estimated to be a blast of about 10,000 tons of TNT. The Atomic bomb’s intense and destructive power frightened many scientists who were working on the Manhattan Project (Knebel 78). Including the father of the atomic bomb, J. Robert Oppenheimer. Oppenheimer felt as if he had created something that would bring forth destruction to the world, instead of using his brilliant scientific mind to improve and usher the world into an era of peace like he intended to. In fact, many scientists within the Manhattan Project were shocked and against using such a powerful weapon as the atomic bomb against other humans, so much that a group of scientists and

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

The Manhattan Project was created out of the fear of their current enemy, Germany of making the first atomic bomb and using it in the war. The current President of the United States was Franklin Roosevelt. It was seen that Germany was making great advances in the war which worried many. But the people who were very worried were three prestigious scientists. Leo Szilard, Eugene Wigner, and Edward Teller who were Hungarian scientists who immigrated to the United States during the war. Szilard and the other scientists wished to advocate for the start of a program that put all efforts into making an atomic bomb. But of course they were very intelligent on how to get their cause across seriously. “Though the three men, particularly Szilard, were well known

     When the first atomic bomb was detonated in Alamogordo New Mexico on June 16, 1945, all the scientists involved in the Manhattan Project understood the great destructive power of radio-active isotopes. Although the atomic bomb was a very destructive force our world would not be as good without it. Because of the government funding involved in the project coupled with the need for an atom bomb, much research that otherwise may not have occurred took place in the US. The Manhattan project opened the door to nuclear advancements and applications.

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.

On December 7th, 1941, Japan attacked the United States first at Pearl Harbor. August 6, 1945, the United States became the first country to use an atomic weapon. Truman made the decision to drop the bomb on Hiroshima because there wasn’t much else to do in the situation.

In August of 1942, the American government began the Manhattan project to develop and build the first nuclear weapon. On a Monday morning, July 16th of 1945, this weapon was tested at New Mexico, and was a success. Shortly after, in August of the same year, the U.S. dropped an atomic bomb over Hiroshima, Japan, and three days later another bomb over Nagasaki, Japan. An estimated 140,000 peopled died in the first blast, and 80,000 in the second, with untold numbers later dying of cancer and other radiation effects. (It should be noted that these cities are once again inhabited, though the location of the nuclear reactor meltdown in Chernobyl, Russia is not. The Chernobyl incident contained much more nuclear fuel—the largest bomb, which exploded over Hiroshima had 140 pounds of uranium, two of which actually reacted, while the Chernobyl reactor had 180 tons, six tones of which escaped.)

The biggest question of the Manhattan project that still lingers today is if the bombs were necessary to end the war. The bombs wreaked havoc on Japan, ensuing large death tolls and city-wide destruction. Everything in the path of the bombs was left to almost dust. The worst part was that many of the people did not see it coming nor had anything to do with the involvement of the war. Not only did the bombings demolish everything within their blast radius, they also left people and animals miles and miles away with intense radiation poisoning. To this day, some people still must live with the harmful affects of radiation. However, Japan was a great enemy to the United States and the idea of bringing thrm to their knees gave high hopes to the men and women devoted to the building of

The decision to drop the bomb on Hiroshima and Nagasaki was the hardest decision for President Truman to make. He had the power right there in his hands to end the war but he would have to unleash the most powerful weapon known to man, at this time. Everyone was very tired of fighting but the Japanese would not give up so Truman decided to drop it. Even though we told Japan that if they did not surrender we would completely demolish some of their cities, they did not listen and they did not surrender. Maybe they did not think about what kind of weapons we would use because
