The atomic bombings of Japan by United States were held in August 1945. On August 6, 1945 an atomic bomb exploded, almost completely destroying the city of Hiroshima. Three days later, on August 9, the second bomb wiped another city, Nagasaki. The fundamental decision about the bombing was made by President Truman on May 31, 1945. After two weeks the first targets were named: the Japanese city of Kokura, Niigata, Hiroshima, and Nagasaki.
A purely political and not a military purpose of US nuclear campaign confirms that neither Hiroshima nor Nagasaki had Japanese strategic military installations capable at the moment to significantly affect the course of the war. Of course, there were military garrisons, factories and bases, but even the largest military shipyard, Mitsubisi, in Nagasaki, which built most of the Japanese battleships and aircraft carriers, in August 1945, had no fundamental significance for the conduct of further hostilities.
By the beginning of August 1945, bombs intended for the Japanese cities, were prepared and sent to the US air base at Tinian on Mariana Islands in the Pacific Ocean. The first bomb was 3 meters long and 0.7 meters in diameter and weighed about 4 tons. The second bomb was twice as thick (1.5 m). The first bomb used uranium-235 and the second bomb had a much more powerful substance – plutonium-239.
On August 6, 1945, bomber B-29 titled Enola Gay rose from the Mariana Islands and headed for Japan, with the first bomb on board. In the morning it reached its goal – Hiroshima –dropped a bomb by parachute bomb which exploded at 8: 15 at a height of 500,600 meters above the ground.
The explosion was heard over the business center of the city at a time when people were rushing to work. As a result, within a radius of 1-1.5 km from the epicenter of the explosion people simply disappeared in an instant. A shock wave shattered in a radius of 3 km everything that had not melt at the outbreak, and raced on, turning the city into the desert. The radioactive contamination of the density of about 400 rad (lethal dose for humans) started after that and ruined the rest. The exact number of victims is still unknown, but it is roughly estimated that 92% of all buildings were destroyed and 130,000-140,000 people died in Hiroshima.
In Nagasaki, everything was different. Even though the bomb that was dropped on Nagasaki was bigger, the hilly terrain area of the city redeemed the bulk of the shock wave, and the numerous folds of the terrain have helped residents escape light radiation. The number of victims in Nagasaki was twice less than in Hiroshima – 60,000-70,000 people. The country was shaken by an unprecedented tragedy in the history of the world.
