During World War II, Hitler was developing the sciences to use an extremely dangerous weapon that is widely known as the Atomic Bomb. The United States was completely unaware of the advances Germany was making at the time; however, Albert Einstein informed President Truman about what was actually occurring through a letter that explained in coherent detail what this bomb was capable of and how Hitler was going to use it. It was now a race between countries on who would be the first one to develop this bomb. Thus the research to build an Atomic Bomb commenced for the United States; a project known as the Manhattan project in 1942 involved more than 100,000 scientists who were participating in secret research, but not before the bombing of Pearl …show more content…
The war between the Japan and United States was catastrophic; thousands of United States military men were dying. At the time, the United States was undergoing six months of excessive strategic fire-bombing of at least thirty-seven Japanese cities. In March 1945, a firebombing in Tokyo reportedly took over 120,000 Japanese lives, and the surrender made with Japan at Potsdam was being ignored by the Japanese military. Due to such circumstances, President Truman was planning an Allied invasion that would take place on Japan’s home islands; this war strategy was predicted to have over hundreds of thousands of casualties from both sides. These plans changed when the atomic bomb was invented. The war was dragging on, no end in sight and the death tolls were growing; therefore, President Truman had to come to a conclusion that would forever alter the ways of war between the United States and other countries. The official research and construction of the Atomic Bomb took place faster than what President Truman was ever expecting because the first successful trial run took place in New Mexico on July 16, 1945. The final product was made in perfect
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”).
After being taken by the Germans convinced others that they still had the lead in developing a fission weapon. It all started with the “Hungarian conspiracy” that had everyone convinced that the creation of a nuclear bomb was possible, but that the German government was already doing research in this field of study on such a weapon. To the rest of the world, the thought of Adolf Hitler might be the first to gain control of a weapon this destructive would be terrifying to the United States. Right, then they decided that the administration of President Franklin D. Roosevelt must be warned about the dangers and that the United States must begin its research department. As the planned gave way, Einstein was to write a letter to President Franklin D. Roosevelt about the possibilities and dangers of the atomic weapons, and later was taken to the president.
Atomic Bomb in World War 2 During World War II the United States government launched a $2 billion project. This project, known as the Manhattan Project, was an effort to produce an atomic bomb. This project was taken on by a group atomic scientists from all over the world.
Atomic Bomb The use of the atomic bombs on Japan was necessary for the revenge of the Americans. These bombs took years to make due to a problematic equation. The impact of the bombs killed hundreds of thousands of people and the radiation is still killing people today. People today still wonder why the bombs were dropped. If these bombs weren’t dropped on the Japanese the history of the world would have been changed forever. The Atomic bomb took 6 years to develop (1939-1945) for scientists to work on a equation to make the U-235 into a bomb. The most complicated process in this was trying to produce enough uranium to sustain a chain reaction. The bombs used on the cities cost about $2 billion to develop, this also making the U.S. wanting to use them against Japan. “Hiroshima was a major military target and we have spent 2 billion dollars on the greatest scientific gamble in history- and won.” (3) The bomb dropped on Hiroshima weighted 4.5 tons and the bomb used on Nagasaki weighted 10 kilotons. On July 16, 1945, the first ever atomic bomb was tested in the Jamez Mountains in Northern New Mexico, code named “Gadget.” The single weapon ultimately dropped on Hiroshima, nicknamed “Little Boy,” produced the amount of approximately twenty- thousand tons of TNT, which is roughly seven times greater than all of the bombs dropped by all the allies on all of Germany in 1942. The first Japanese City bomb was Hiroshima on August 6, 1945. An American B-29 bomber, named Enola Gay, flown by the pilot Paul W. Tibbets, dropped the “Little Boy” uranium atomic bomb. Three days later a second bomb named ”Fat Boy,” made of plutonium was dropped on the Japanese city of Nagasaki. After being released, it took approximately one minute for Little Boy to reach the point of explosion, which was about 2,000 feet. The impact of the bombs on the cities and people was massive. Black rain containing large amounts of nuclear fallout fell as much as 30km from the original blast site. A mushroom cloud rose to twenty thousand feet in the air, and sixty percent of the city was destroyed. The shock wave and its reverse effect reached speeds close to those of the speed of sound. The wind generated by the bombs destroyed most of the houses and buildings within a 1.
In fear that Nazi Germany was developing an atomic bomb, on December 6 1941, scientists, engineers and the army raced to build the first man-made atomic bomb. These combined efforts provide the United States with wartime military advantage was dubbed ‘The Manhattan Project’. However, when by late 1944, concrete intelligence confirmed that Germany’s work on atomic weaponry had basically stalled in 1942, many scientists were given cause to pause and reassess their commitment to the project. Joseph Rotblat, for instance, quit the project maintaining that, ‘the fact that the German effort was stillborn undermined the rationale for continuing’. Indeed, he was the exception. Nevertheless, the scientists’ apprehensions reached a high plateau when Germany surrendered in May 1945. These events, among others, suggested that the bomb would be used, if at all, against Japan (a reversal, in a way, of the racism and genocide issues within Germany). Many scientists, thus, began to debate among themselves the moral and ethical implications of using an atomic bomb in the war and the fate of humanity in the imminent atomic age. In doing so, the scientists with a stronger sense of responsibility, resolved that, as they had created the bomb, they possessed both the legitimacy and intellect to formulate proposals regarding its use. On their political mission, the scientists fastened...
After Truman decided to bomb Japan, they had to plan it out. They first had to decide where to release the bomb. They ended up choosing Hiroshima, Japan and Nagasaki, Japan as their two locations. Hiroshima was a significant military city in the war. It confined two army headquarters and was Japan’s communication center (World War 2 Atomic Bomb 1). Hiroshima was also a huge industrial city and had not been bombed before so it would let Japan see the wrath of the United States (Koeller 1). The planning and actual event of the bombing went great. On August 6, 1945 at 8:15 in the morning the bomb was dropped. The bomb that landed in Hiroshima was called the “Little Boy” (World War 2 Atomic Bomb 2). The bomb ended up killing about 170,000 people. 70,000 people died the first day and 100,000 people died in the next few months due to the radioactivity of the bomb and burns fro...
The attack at Pearl Harbor was the event that caused the U.S. to decide to be involved in the war. After this incident, the U.S. was trying to find a way to retaliate and counterattack against Japan. Some thought that the only way to do so was by using atomic bombs. People like, General Dwight Eisenhower, Harry S Truman, and a group of scientists believed that the use of the bomb would do good, and finally end everything. Eisenhower believed that because the use of the atomic bomb was successful in New Mexico, it would also be successful in Japan as well. Harry S Truman thought that even the atomic bomb was the most destructive weapon in the history of the world, it could be made the most useful. He stated that, “it was ...
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
When looking at the aftermath of the atomic bomb in both Nagasaki and Hiroshima the devastation it caused is evident. The majority of the population in Japan could have never imagined such a catastrophic event. On August 6, 1945 and August 9, 1945 massive amounts of lives were changed forever when an atomic bomb fell from the sky and created an explosion as bright as the sun. These two bombs were the first and only accounts of nuclear warfare. (“Atomic Bomb is…”) The impact that the two bombs left on the cities of Japan was tremendous. The bombing of Nagasaki and Hiroshima devastated the country through structural damage, long term medical effects, expenses, and the massive loss of life.
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...
In 1945, the United States was facing severe causalities in the war in the Pacific. Over 12,000 soldiers had already lost their lives, including 7,000 Army and Marine soldiers and 5,000 sailors (32). The United States was eager to end the war against Japan, and to prevent more American causalities (92). An invasion of Japan could result in hundreds of thousands killed, wounded and missing soldiers, and there was still no clear path to an unconditional surrender. President Truman sought advice from his cabinet members over how to approach the war in the Pacific. Although there were alternatives to the use of atomic weapons, the evidence, or lack thereof, shows that the bombs were created for the purpose of use in the war against Japan. Both the political members, such as Henry L. Stimson and James F. Byrnes, and military advisors George C. Marshall and George F. Kennan showed little objection to completely wiping out these Japanese cities with atomic weapons (92-97). The alternatives to this tactic included invading Japanese c...
Why did the United States drop the Atomic Bomb? 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 at this time due to the fear of Mutually Assured Destruction (MAD).
In 1939 rumor came to the U.S. that Germans had split the atom. The threat of the Nazis developing a nuclear weapon prompted President Roosevelt to establish The Manhattan Project. Oppenheimer set up a research lab in Los Alamos, New Mexico and brought the best minds in physics to work on the problem of creating a nuclear weapon. Although most the research and development was done in Los Alamos, there were over 30 other research locations throughout the project. After watching the first nuclear bomb test Oppenheimer was quoted as saying simply “It works.”.
