The Manhattan Project Essay

The Manhattan Project was a secret problem barely anyone knew about.Many of the scientists that were involved with the Manhattan Project heard about the Axis powers gaining knowledge of how to make nuclear weapons that could destroy a whole nation.The Manhattan Project produced two atomic bombs that were dropped on Japan.The atomic bombs were dropped on Hiroshima and Nagasaki.Hiroshima was chosen as the target for the first atomic bomb because it was a large port city with an army base. The bomb dropped on Nagasaki missed its target by over a mile.

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

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

The first atomic bomb that Japan was to get a glimpse of was on August 6th, 1945, during World War II in the city of Hiroshima. The explosion annihilated 90 percent of the city; without hesitation killed 80,000 people. More than tens of thousands of people would have eventually died due to radiation exposure. Within three days of the attack, a second B-29 dropped another A-bomb in another location known as Nagasaki, killing an estimation of 40,000 people. Hirohito, Japan’s emperor announced his country’s unequivocal surrender in WWII in a radio address on August 15th, in allude to the calamitous power of “a new and most cruel bomb.” President Truman had to make one of hardest pre arrangements that he had ever faced. Truman based this decision off of the results of to justify the cost of the Manhattan project, in response of

On August 6, 1945 an explosion blew up the city of Hiroshima. It was reduced to rubble. In the months leading up to the bomb, WWII was close to being over. Germany had surrendered but Japan wasn't ready to give up without a fight. The USA issued a warning to Japan but Japan ignored it. The USA went ahead with their plan and dropped the atomic bomb from a B-29 which brought havoc to Hiroshima. The bombing of Hiroshima was justified because it saved American lives, the Japanese had been given an ultimatum and the bomb was a retaliation for the bombing of Pearl Harbor.

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 dropping of the atomic bomb on Hiroshima on August 6th, 1945 and Nagasaki on August 9th, 1945 was the first and last time the weapon has been used to date; the atomic explosions exposed the true potential of nuclear warfare whilst also highlighting the global superiority that America possessed at the conclusion of World War II. On August 6th 1945 “Little Boy”, a uranium atomic bomb was dropped on Hiroshima in an effort by the United States backed by the Soviet Union, the British and the Chinese to force a Japanese surrender. However American intelligence suggested no evidence of Japanese surrender which acted as the catalyst for the second use of a plutonic implosion type bomb, “Fat Man” on Nagasaki on August 9th 1945. The sheer force of the bombs reportedly killed 66,000 in Hiroshima and 39,000 in Nagasaki Japanese residents whilst injuring another 94,000 residents suffering symptoms of intense third degree burns.

On August 6, 1945, “Little Boy” the first atomic bomb, was dropped on the city of Hiroshima and three days later, “Fat Man” a second bomb, was dropped on Nagasaki, resulting in the untimely death of over 20,000 people. This was done as an offensive and retaliation by the United States of America, whom had feeling of revenge and an unwavering desire to end an ongoing war as quickly and decisively as possible, against the Japanese for the bombing of Pearl Harbor. However, this took place right after a demand for an unconditional surrender of the Japanese by the Allied leaders by means of a Potsdam Declaration, in late July 1945, was flatly rejected by Japanese leaders. Thus resulting in the use of these atomic bombs being authorized by President Truman.

What is the Manhattan Project?The point of the project was for the U.S to design and create nuclear weapons.The project was running slow until August 1942,where the U.S army took over.The U.S army changed the name of the project to The Manhattan Engineer District (MED)gen.Leslie R.Groves was

On August 2, 1939, just before the beginning of World War II, Albert Einstein wrote to then President Franklin D. Roosevelt. Einstein and several other scientists told Roosevelt of efforts in Nazi Germany to purify uranium-235, which could be used to build an atomic bomb. It was shortly thereafter that the United States Government began the serious undertaking known then only as "The Manhattan Project." Simply put, the Manhattan Project was committed to expediting research that would produce a viable atomic bomb.

The Manhattan project was a top secret government enterprise that was put in place to create the worlds first atomic bomb. Overall, The Manhattan Project was a 2.2 billion dollar program in which was a collaborative effort between both British and also American scientists. The project was put into place to create the worlds first ever atomic bomb and to use the bomb in World War II. The projects official start was in 1943 and it 's official completion was in 1945. The Manhattan Project, also, employed over 130,000. The bomb was to be under strict secrecy from Germany, Japan, Russia, and even some parts of America 's executive system.

The Manhattan Project played large role importance as it helped greatly with the development of technology at time as well as preventing a long process of invasion with even more casualties. The project ended WWII, as 3 days after dropping two atomic bombs on

On April 12, 1945, President Roosevelt’s death occurred. Harry Truman appropriated the project and the Secretary of War brought him up to date since he was always unaware of the task at hand. President Truman convened with Winston Churchill and Joseph Stalin and the Potsdam Declaration was written. This declaration offered Japan the opportunity to surrender or risk “prompt and utter destruction” Japan declined and President Truman was left with the decision to release nuclear destruction on Japan. On August 6, 1945, “little boy” the first atomic bomb was dropped on Hiroshima. Truman had picked the target based on the lack of American civilians in the area. Japan refused to surrender. Three days later “fat boy” the second atomic bomb was released on Nagasaki, the residency of the Mitsubishi factory that produced the torpedoes that bombed Pearl Harbor. The devastation and deaths were felt for months after the bombing. The staggering amount of deaths were reported to be between 90,000-146,000 people in Hiroshima and 39,000-80,000 in Nagasaki. Half of these deaths occurred on the days of the bombings. Japan surrendered to the United States. World War II would be ending.

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.

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).
