Deaths from the bombings are estimated to be around 150,000. It was the first time nuclear weapons had been used, followed three days later by the bombing of Nagasaki. Kennedy also encouraged Americans to build private shelters, the estimated number of which rose from 60,000 in June 1961 to some 200,000 in 1965.August 6 marks the seventy-fifth anniversary of the atomic bombing of the Japanese city Hiroshima. Kennedy expanded the nation’s civil defense programs, calling for more than $200 million in appropriations for the construction of public fallout shelters in the United States. Community shelters were constructed beneath municipal buildings, and emergency government bunkers were carved into hillsides.ĭuring the crisis over Berlin in mid-1961, President John F. Families across the country (at least those who could afford it) built fallout shelters in their basements and backyards.

In schools, children learned to “duck and cover,” diving under their desks and staying far away from windows in drills designed to protect them during an atomic strike. With Cold War tensions escalating in the 1950s, the threat of a Soviet nuclear attack cast a terrifying shadow over everyday American life. The fear of nuclear war also affected people in the US. The Atomic Bombs ended the war a good few months ahead of schedule, and saved countless lives. An invasion would have been a bloodbath, a devastating ordeal for both of the sides involved in it.

Schoolgirls were taught how to fire, reload and maintain standard issue combat rifles to defend the home islands, an entire air wing was in reserve to use as Kamikaze attack planes to disrupt shipping and to sink landing craft. Every able man, woman and child were armed with what was left of the available arms. The Japanese sought to perform Ketsu-go or "Decisive Battle" to weaken the allied advance, if not outright destroy it, and force the allies to retreat. To quote President Truman, he knew that an invasion of the Japanese home islands would be an "Okinawa from one end of Japan to the other." a bloody struggle. In fact, the Japanese Government formed a National Militia to defend the home islands in case of invasion.
These invasions would have resulted in the deaths of millions of allied troops and an larger, untold number of Japanese military personnel and civilians. Operation Downfall would oversee these invasions and would provide logistical support. 1945 focused on taking Kyushu island while Coronet focused on taking the areas around Tokyo in Spring, 1946. Operation Olympic, planed to commence in Nov. Truman chose the atomic bombs over an invasion of the home islands of Japan, these invasions were called Operation Olympic and Coronet, classified under Operation Downfall. The Atomic Bombings were necessary to end the war quickly with the least amount of bloodshed. Sorry for the over-detailed paragraphs and complex wording. Estimates say that only about 20% of the 13.6 pound P-239 core underwent fission, throwing the other 11 pounds away, scattered in the nearby areas. Conventional explosive, surrounded by Uranium-238, were placed around the plutonium core, and when they exploded, they sent a shock wave of energy and force, which was reflected by the U-238 by its neutron reflecting properties, to the aforementioned core, causing it to undergo nuclear fission. The material that fueled it was Plutonium-239. The bomb that was used on Nagasaki, "Fat Man," was an imploding-type bomb that was more powerful, as well as complex. Once the "bullet" has struck the spike at the front, the atoms split, causing an explosion, along with a mushroom cloud. Basically, a small explosive in the back launches a hollow uranium "bullet" to the front of the bomb, where a target cylinder or spike of sorts is waiting for it. The first bomb, which was used on Hiroshima, "Little Boy," was a Uranium-235 gun-type fission weapon. This process is called "nuclear fission." There are two types of bombs that were dropped. It can be achieved by bringing an element to "critical mass," which means that it's so dense that it can't be packed any tighter. When aforementioned atom is split, massive amounts of energy are released. The way the bomb works is this: inside of the bomb, an atom is split.
