During World War II, the US dropped Nuclear Bomb On Hiroshima and Nagasaki two main cities of Japan. On August 06, 1945, the US dropped the first atomic bomb on the Japanese city of Hiroshima, three days later, a bomb was dropped on Nagasaki. Millions of people were killed in one stroke, and more were killed by the radiation caused by the bomb. After this bomb, the Second War in Asia ended. The Japanese forces began to retreat, about a week later, Japan also surrendered to the Allied coalition.
The bomb was dropped on Hiroshima on 6 August 1945 at 8:15 am. The name of this bomb was Little Boy. It was filled with about 60 kg of uranium and was 10 feet long. Due to the reverse wind, it exploded over the Shima Surgical Clinic, about 800 feet from its designated target, the Sheoi Bridge. The explosion was equivalent to about 13 kilotons of tin. As a result, the area of about 1.6 km was completely destroyed.
The area of 11 sq km was engulfed in flames and burnt. According to US officials, an area of 12 square kilometers was completely destroyed by this bomb. Japanese officials claimed that 69 percent of the buildings in Hiroshima City were completely destroyed and that 6.7 percent of buildings were partially damaged. The clouds created by the atomic bombings caused heavy rain in Hiroshima around 11am.
On August 9, the second bomb was dropped on Nagasaki, the port city of southern Japan, at 11:1 a.m. The name of the bomb dropped on Nagasaki was Fat Men. The second time the atomic bomb was dropped, it weighed 4500 kg and was 11.5 feet in length. The bomb contained 6.4 kg of plutonium, which was more dangerous than uranium. After 43 seconds, the bomb exploded at a height of 1,540 feet above the ground and caused an explosion equivalent to 21 kilotons of tin. As a result, heat of 3,900 ° C was generated and the wind speed reached 1005 km per hour. The number of immediate deaths due to this was estimated to be between 40,000 and 75,000. By the end of 1945, this figure reached 80,000.
Why did America drop Nuclear bomb on Hiroshima and Nagasaki ?
Harry S Truman was the President of the United States at that time. The Japanese army decided to target Indo-China with the intention of capturing the oil-rich regions of the East Indies. Harry S Truman warned, “Japan must either surrender or prepare for immediate and utter destruction. We are capable of destroying any city in Japan by air.” US President Harry Truman launched a Nuclear Bomb On Hiroshima and Nagasaki on Japan to force surrender. However, there are other theories regarding this.
One historian, Gar Alperowitz, argued in a 1965 book that Japanese cities were attacked in order to gain a stronger position for diplomatic negotiations with the Soviet Union after the war. Japan bowed down after seeing the huge devastation and surrendered to America and the Second World War ended. For many years after the nuclear attack, children with disabilities were born in the cities around these Japanese cities due to nuclear radiation.
