The Atomic Bomb and the Manhattan Project
It was December 7, 1942 a beautiful mourning in Pearl Harbor. When out of the blue, hundreds of Japanese planes bomb and either sunk or severely damaged eight battle ships and at least thirteen other naval ships that were docked on the shore. This spark is what involved the United States the forest fire known as World War II. My paper is not on the war itself, but is on the atomic bomb, and what was known as the Manhattan project. In my report I will talk about the many reasons, the atomic bomb had to be created and used.
The atomic warfare capabilities of the United States were brought about in a letter from Mr. Albert Einstein to Franklin D. Roosevelt, our current president at the time. “It may be possible to set up a nuclear chain reaction in a large mass of uranium, by which vast amounts of power and large quantities of new radium-like elements would be generated…. It is conceivable, though much less certain, that extremely powerful bombs of a new type may thus be constructed.” His letter was the inspiration for the atomic bomb. Although it took a while for Roosevelt to realize what we had stumbled upon, his close friend Alexander Sachs helped him realize the possibilities. Two years later in November Roosevelt appointed a committee to advise him on nuclear fission and the capabilities of the concept in war. At the head of this committee was Secretary of War Henry L. Stimson. About a month later, an event happened that would change the history books forever. The Japanese bombed Pearl Harbor, Hawaii at about 7:50 in the mourning. This brought America into the war and the Manhattan Project was on its way. The Manhattan Project included the designing and construction of the atomic bomb, and the execution of dropping the bomb on Hiroshima and Nagasaki. There were three major research and production sites for the project. The first was Los Alamos, near Alamogordo, New Mexico. This is where the actual weapon would be designed. The head of this site was Julius Robert Oppenheimer; this caused a small uproar because of past involvement in pro communist’s activities. The second site for the Manhattan Project was in Oak Ridge, Tennessee. At this site, scientist and laborers were separating U-235 from U-238. Here the Hiroshima bomb was built in huge buildings and the locals could only imagine...

...s. On April 6, 1945 at about 8:15 AM, before air raid alarms could go off, little boy exploded. The temperature was estimated to reach over 1,000,000 degrees Celsius. This bomb initially killed about a hundred thousand people, then injured about the same amount, and that does not include how many it killed after the blast from exposure to the radiation. Two days after the first bomb was dropped the U.S.S.R declared war on Japan. On August 9, we dropped the bomb on Nagasaki at about 10:58 AM. The results were slightly greater than the Hiroshima bomb. This bomb caused these cities to turn into complete rubble, there was nothing left standing with in a four square mile radius of where the bomb hit. So on September 2, 1945; General MacArthur accepts Japans formal surrender aboard battleship Missouri in Tokyo Bay. Therefore, the tragic war ends quicker than anyone could have ever imagined. The US now has a new weapon to use in warfare and have set up bases in Japan. So I ask you was the atomic bomb a god thing or a bad thing for our society. It helped us win a world war and helped us become a super-power of the world but it also is now one of the great dangers of the world. You decide…
The super bomb in which America and Russia were trying to build was in fact the Hydrogen Bomb. This bomb had an unlimited blast potential and for the country who possessed it unlimited power. The A-bomb’s explosion was based on the principal of fission (the splitting of atoms), however the H-bomb’s explosion was base on fusion (the coming together of atoms). In August of 1945 Russian President Stalin, turns up the nuclear project in Russia. He put Barria whom was in charge of the secret police, to head the Russian Nuclear program. An American scientist named Edward Teller solicited the American government to build the H-bomb. He was born in Hungary and had learned to fear the communists and the Russians. In April of 1946 the Super Conference was held. Klaus Fuchs was a scientist that worked for Teller at Los Alamos, he told the Russians how to build the A-bomb, and also about Tellers ideas of the H-bomb. He was arrested for spying for the Russians. By chance the Americans found out that there were traces of radioactive material in the air over Russia. They pieced together that Russia had the A-bomb they decided to go ahead with plans to build the super bomb. President Truman came to the conclusion that no matter how bad of a weapon the H-bomb was if was better if we had if first. America had lost some of its power and wanted to gain a new edge. General Curtis Lamay was put in charge of Strategic Air Command to protect America from the threat of nuclear war. Lamay was the ranking Air Force General over the Skies of the pacific and was the man for the job. His strategy was to have an abundant amount of bombers ready to strike every major city in the Soviet Union. He wanted everyone in the Army and Air Force to act as if war was not far away.
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”).
...s who would do anything to win their war so a powerful weapon was needed to weaken their will. The bomb?s intense impact saved more soldiers? and civilians? lives involved in the war than it destroyed. The damage the atomic bombs produced was miniscule compared to the massacres the Japanese militarists created. The bomb clearly improved American foreign relations, especially with the Soviet Union. The choice to use the atomic bomb was justified because it coerced a Japanese surrender, saved countless lives, served as retribution for the sufferings of many people, and acted as an anti-Soviet deterrent.
The Manhattan Project The Manhattan Project was a research project, that created the United States first nuclear weapon, and led to its creation of the nuclear department during World War II. M.A.U.D. / M.A.U.D. group was created in 1940. Also, M.A.U.D was the secret name given to the group and it came from a phrase in a message from Niel Bohr (Cohen). This group produced a report that said that producing a fission bomb was possible. James Chadwick, a new member of the British M.A.U.D group, later wrote that at that time he realized that a nuclear bomb was able to be built in his lifetime.
Under President Franklin D. Roosevelt’s administration the atomic bomb was being developed. After Roosevelt died, his vice president Harry Truman was appointed President of the United States. Truman was never informed about the bombs development until an emergency cabinet meeting (Kuznick 9). Truman had to make the fatal decision on whether the bomb was to be dropped on Japan. With the idea of going to war, Truman had to think about the lives of the thousand American soldiers. The American soldiers had begun using the method of island hopping, because the bomb was not available. The idea of dropping a bomb was that the war itself could possibly end in its earliest points. The dropping of the atomic bomb could also justify the money spent on the Manhattan Project (Donohue 1). With a quote by Franklin D. Roosevelt “This will be a day that will live in infamy”, Pearl Harbor was a tragic day for Americans. The United States had lost many soldiers, which they had claimed that they will eventually get revenge. The alternates of dropping the bomb was also discussed at the Interim Committee. The American government was trying to get an invitation response from the Japanese government. If the United States did not drop the bomb and ‘Operation Downfall’ ha...
On August 6th, 1945, the United States of America dropped the world’s first atomic bomb on the city of Hiroshima in Japan. Two days later, a second bomb was dropped on the city of Nagasaki. These two bombs were the most devastating weapons ever seen, and their effects on human beings and property were plainly horrifying. Approximately 110,000 people were killed; most of them were innocent civilians who just happened to have lived in the wrong place at the wrong time. Although using this weapon was an atrocity to both the Japanese, and humanity in general, the world was at war. No matter what ulterior motives may have existed, the fact remains that the bomb was a justifiably necessary measure to bring an early end to aggressive war that was instigated by Japan. Japan would never have surrendered unconditionally, as decreed in the Potsdam Ultimatum. Invasion of the Japanese home islands were out of the question because of the ferocious defense that would have been staged, and the huge number of casualties that it would entail. The bomb shocked the Japanese militarists into surrender and gave the “peace-party” the added credibility they required to bring about a quick end to the war. The use of the bomb also kept Russia out of the war, preventing problems that had occurred in post-war Germany, and later on in Korea. When all factors are taken into consideration, the use of the atomic bomb actually saved more lives, both Japanese and American than it took.
The road that led to the bombing of Hiroshima was a long and covert one. In fact, the research and development of the atomic bomb was so secretive that when Vice President Harry S. Truman entered the Presidency following the death of Franklin D. Roosevelt, he had no knowledge of it. Yet he would be the central figure in making the decision to use the bomb. In April 1945, Secretary of War Henry Stimson(pictured - left) and General Groves briefed Truman(pictured - right) about the "Manhattan Project", the top-secret program that researched and developed the atomic bomb.2
...e atomic bomb on Japan was extremely controversial it ultimately ended in America’s favor when Japan surrendered. According to Karl Compton, “it was not one atomic bomb, or two, which brought the surrender; it was the experience of what an atomic bomb will actually do to a community, plus the dread of many more, that was effective.” Hiroshima and Nagasaki will always serve as a reminder of the tremendous effects powerful weapons can have on a country. America consciously decided to seize Japanese lives in order to save American lives. The attack effected Japan in a massive amount of negative ways but the outcome of the atomic bomb did create positive effects for America. The devastation generated by the atomic bomb will never be forgotten by citizens worldwide. “The atomic bomb was more than a weapon of terrible destruction; it was a psychological weapon.” (Stimson)
The U.S. decided to develop the atomic bomb based on the fear they had for the safety of the nation. In August 1939 nuclear physicists sent manuscripts to Albert Einstein in fear the Germany might use the new knowledge of fission on the uranium nucleus as way to construct weapons. In response, on August 2, 1939, Einstein sent a letter to President Roosevelt concerning the pressing matter to use uranium to create such weapons before Germany (Doc A-1). To support the development of the atomic bomb, President Roosevelt approved the production of the bomb following the receipt that the bomb is feasible on January 19, 1942. From this day to December of 1942, many laboratories and ...
As World War 2, came to a close, The United States unleashed a secret atomic weapon upon the enemy nation of Japan that was quickly recognized as the most powerful wartime weapon in human history. They completely destroyed the entire Japanese cities of Hiroshima and Nagasaki, and essentially vaporized countless innocent Japanese lives. Some historians believe that it was a foolish, brutal decision to use the atomic bomb on a weakened Japan, and that the civilians of the country did not deserve that kind of mass-annihilation. On the opposite side, other historians assert that dropping the bomb saved countless American and Japanese lives by ending the war faster than a regular invasion would have. What is undisputed is that this sad event dramatically changed the course of human history.
The United States’ decision to drop an atomic bomb on Hiroshima required extensive research leading to its production. The main goal of the American side was to damage the enemy’s confidence, while choosing a target with the highest military output in order to conclude the war (Robinson).The group in charge of developing the technology was known as the Manhattan Project, and was kept top-secret. Selection began in the spring of 1945, with assistance from the Commanding General, Army Air Forces, his Headquarters (Robinson).There was a variety of experts working on the project, including mathematicians, theoretical physicists, and specialists trained in weather and blast effects Headquarters (Robinson). In order to monitor all of the results, the city had to be untouched, meaning the target had to have no signs of previous bombings. Based on these requirements, the designation of Hiroshima for the bombing was not a simple determination. After a target was selected and the weapon was developed, testing was set to begin. On July 16, 1945, the first test in Alamogordo, New Mexico, proved that the bomb was prepared for release onto...
World War II brought up many new technologies for warfare. Advanced on existing developments such as weaponry, ships, vehicles air crafts, navigational devices and medicine are just a few broad examples of developments in warfare during this time in United States and World history. One development, however, changed the entire way of warfare. The Atomic bomb was developed during this time out of fears that the Germans had the same technologies, or at least were working to obtain it. Once the United States had this technological capability of producing atomic weapons, the way of fighting was changed. Two bombs were dropped on Japan in August of 1945, one on the city of Hiroshima and the other on the city of Nagasaki. Afterward, the ear of atomic diplomacy came up in American international relations, which as we have seen today, has led to the development of even stronger, more deadly weaponry and bombs. The bombing of Japan also brings up the still prevalent debate of whether the bombings were justifiable or not. Historians Gar Alperovitz, Robert P. Newman and Barton Bernstein all have written essays expressing their opinions in the matter.
At 5:30 AM July 16th 1945, the nuclear age had started. The world’s first atomic bomb was detonated. On August 6th 1942 at 8:15 AM, an American B-29 bomber, the Enola Gay, dropped a perfected atomic bomb created by the Americans, over the city of Hiroshima hoping to end the war. Thousands of people died in the two cities in Japan. They were Hiroshima and Nagasaki “the Manhattan Project”. The research and development project that produced these atomic bombs during this time was known as “the Manhattan Project”.
Although WW II ended over 50 years ago there is still much discussion as to the events which ended the War in the Pacific. The primary event which historians attribute to this end are the use of atomic bombs on the cities of Hiroshima and Nagasaki. Although the bombing of these cities did force the Japanese to surrender, many people today ask “Was the use of the atomic bomb necessary to end the war?” and more importantly “Why was the decision to use the bomb made?” Ronald Takaki examines these questions in his book Hiroshima.
The atomic bomb is the subject of much controversy. Since its first detonation in 1945, the entire world has heard the aftershocks of that blast. Issues concerning Nuclear Weapons sparked the Cold War. We also have the atomic bomb to thank for our relative peace in this time due to the fear of Mutually Assured Destruction (MAD). The effects of the atomic bomb might not have been the exact effects that the United States was looking for when they dropped Little Boy and Fat Man on Hiroshima and Nagasaki respectively (Grant, 1998). The original desire of the United States government when they dropped Little Boy and Fat Man on Hiroshima and Nagasaki was not, in fact, the one more commonly known: that the two nuclear devices dropped upon Hiroshima and Nagasaki were detonated with the intention of bringing an end to the war with Japan, but instead to intimidate the Soviet Union. The fact of Japan's imminent defeat, the undeniable truth that relations with Russia were deteriorating, and competition for the division of Europe prove this without question.
