Atomic Bomb History

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

The first atomic bomb was dropped on the city of Hiroshima, one of the larger cities of the country of Japan. The announcement that an atomic bomb had been dropped on Japan came from Truman as a “scientific landmark and the age of atomic energy” . This power came as not only for the advancement of civilization, but also the ability for civilization to be

With the start of World War II the race for the first atomic bomb started. With Germany under Hitler’s reign, the Nazis began separating uranium to form the first atomic bomb to control the world. The push for the United States build the first atomic bomb began with this knowledge. With the help of several scientists the United States succeeded in building the atomic bomb first. Two atomic bombs were used; a uranium bomb on Hiroshima and a plutonium bomb on Nagasaki. Along with the many deaths were six stages of A-bomb illness which includes acute stages, atomic bomb trauma, A-bomb radiation illness, radiation blood injury at lethal dosage, blood injuries, and secondary radiation illness. Seven unhealed scars were also an effect of the atomic bombs that includes keloids, A-bomb cataracts, leukemia, cancers, chromosome changes, exposure in utero and microcephaly, and genetic surveys. Regulations and guidance were set in place soon after the bombings to protect the people of the world based on the information that was gathered and it has changed over the years based on the new information that was learned. With the use of the atomic bombs in World War II, a lot of pain and suffering was caused, but a great deal of information was learned to help protect future generations from radiation.

Nearly seventy years later, there is still controversy amongst the atomic bombs that were developed and dropped during World War Two. These atomic bombs would unleash a force of destruction that the world has never yet seen. The Manhattan Project developed these bombs under their distinct codenames, Little Boy and Fat Man. Little Boy was dropped on Hiroshima August 6, 1945, resulting in approximately 140,000 Japanese casualties. Three days later after the event occurred, Fat Man was dropped on Nagasaki, which resulted in approximately 70,000 casualties. Historians can argue that the atomic bombs were a necessity to win the war. Others can argue that the war was already over and dropping the bombs was completely unnecessary. Although there are many solid points to both arguments, the atomic bombs dropped on Japan was justified.

Part of the city was virtually leveled by the time the dust had settled. Thousands more people died months and years after from injuries and radiation poisoning. The second atomic bomb was dropped on Nagasaki, Japan just 3 days later on August 9th, 1945. The original target for the second bomb, codenamed "fat man", was the city kokura but the target was obscured by clouds over it. This time, over 3.5 square miles of the city was destroyed and over 60,000 people were killed instantly. Also like last time, thousands more people died years after from injuries and radiation poisoning. These two bombs brought about the end of WW2, but they also brought the beginning of the nuclear arms race.

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

“Little Boy” and “Fat Man” were the first atomic bombs created, and delivered revolutionary damage. Little Boy was the first bomb to detonate over Japan. Approximately 90% of people within half a mile from the location of the explosion died almost instantly. Only about 10% of buildings in Hiroshima remained standing or undamaged. The massive explosion happened so fast that clothing patterns burned into the skin of victims far enough away to avoid instant death. Along with this, the blinding flash of light

On August 6, 1945, the 33rd president of the United States, Harry S. Truman, made the executive decision to drop a 10,000 pound atomic bomb named “Little Boy” on the city of Hiroshima in Japan. Three days later, Truman ordered another atomic bomb, called “Fat Man” to be dropped on another Japanese city, Nagasaki. Each bomb had a blast radius of fifty miles. The decision to utilize these weapons of mass destruction will always be a very controversial topic because of the debated morality of the decision.

On 06 August 1945, the United States denoted a nuclear weapon over the Japanese city, Hiroshima due to the major military headquarters the housed. The event took place during the final stage of World War II, it is uncertain to the amount of people harmed in this event, to this day, with the long-lasting effects of the bombing survivors are still taking ill.

Bomb to be dropped was called Fat Man, a plutonium bomb more complex than the one dropped on Hiroshima

Little Boy was an atomic made out of Uranium, it contained 140 lbs. of pure uranium.Its explosive force was equivalent as 15,000 tons of TNT. Little Boy was tested during World War II on Hiroshima in August 6, 1945.The “Fat Man” was a Plutonium bomb. Its explosive force was 10x stronger than Little Boy. Fat Man contained about 13.6lbs. of plutonium,it had the size of a soft ball! It was used against Nagasaki in August 9, 1945.

Less than a month later, the first atomic bomb was dropped on August 6, 1945. (Fat Man and Little

At about eight A.M on August sixth, 1945 the Japanese city Hiroshima was destroyed by the deployment of the first nuclear weapon, nicknamed “Little Boy.” Soon after, at about eleven A.M the following day, a second bomb was dropped, called “Fat Man” on Nagasaki. Together, these bombings caused massive destruction. The death total was well near 220, 000. Only portions of these deaths were from the days of the bombings, with an equal number occurring later in the year from exposure to radiation. More have died since from leukemia.

An atomic bomb is a bomb whose violent explosive power is due to the sudden release of energy resulting from the splitting of nuclei of a heavy chemical element (as plutonium or uranium) by neutrons in a very rapid chain reaction —called also atom bomb. 2 : a nuclear weapon (as a hydrogen bomb)

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).
