The first atomic bomb ever used in human history
When an atomic bomb is dropped on the Japanese city of Hiroshima on August 6, 1945, the United States makes history by becoming the first and only country to employ atomic weapons during a conflict. The explosion directly kills about 80,000 people and also injures another 35,000.
However, the Pacific War against Japan went on in full force. The U.S. President, Truman decided to issue an order to utilize the new deadly weapon to put an end to the war after some of his advisors told him that if they attempted to invade Japan, there would be loss of lives of a large number of American soldiers.
The result of the atomic bomb
The Japanese city of Hiroshima was hit by a five-ton bomb that was dropped by the American bomber Enola Gay on August 6, 1945. A detonation that had the same destructive force as 15,000 tons of TNT destroyed four square kilometers of the city and instantly killed 80,000 people. In the weeks that followed the bombing, over tens of thousands more people perished from radiation sickness and wounds. A second bomb was detonated in Nagasaki three days later, killing close to 40,000 additional people. Japan announced its surrender a few days later.
At the same time as the explosion, the temperature at the point of detonation reached several million degrees Celsius, and the fireball generated in the air became 400 m in diameter after 0.2 seconds.
The heat rays emitted from the fireball in all directions had a strong impact on the ground from 0.2 to 3 seconds after the explosion, and the temperature of the ground surface around the hypocenter reached 3,000 to 4,000°C (melting temperature of iron is about 1,500°C).
The Americans’ haste to terminate the war was incompatible with the Japanese plan. In 1945, the majority of Japanese commanders realized that their cause had been lost, but they still wanted to provoke a decisive conflict that would enable them to surrender while still keeping their government. The Japanese repeatedly engaged in valiant combat in an effort to gain a bargaining position rather than to win the war.
In order to prevent a recurrence of the “stab in the back” narrative that developed in Germany following the end of World War I, the Allies remained steadfast in their desire for unconditional surrender. Whatever its intent, the Allies had no room to maneuver in their negotiations with the Japanese because of this demand.
The 1945 Atomic Bombs Dropped On Japan Killed And Wounded Hundreds Of Thousands.
The bombardment is believed to have killed 140,000 people in Hiroshima and an additional 74,000 in Nagasaki by the end of 1945. In the years that followed the atomic bombing, a high percentage of people who survived got leukemia, cancer, or other horrifying side effects from the radiation.
The explosive yield of the uranium bomb that exploded over Hiroshima on August 6, 1945, was equal to 15,000 metric tons of TNT. By the end of 1945, it had destroyed and burned almost 70% of all buildings, resulting in an estimated 140,000 fatalities and rising rates of cancer and chronic illnesses among the survivors.
Three days later, a slightly larger plutonium bomb over Nagasaki destroyed 6.7 square kilometers of the city, killing 74,000 people by the end of 1945. The ground warmed to 4,000 °C, and radioactive rain fell.
