The Bomb that Changed the World

The Atomic Bomb

    The atomic bombs dropped on Hiroshima and Nagasaki were called "Fat Man" and "Little Boy." They were used by the US as an alternate solution to end World War 2 and make the Japanese surrender instead of an all out invasion of Japan by US forces, which was predicted to inflict huge losses on both sides. The bombs were develped by the US, Canada, and UK in the Manhattan Project. After developing the atomic bombs for six years, they were the first atomic bombs to be used on cities (Hiroshima and Nagasaki). If the Japanese had not surrendered by then, seven more bombs were planned; one more in August and three more in both September and October. Atomic bombs could have been built many different ways. The bombs dropped on Hiroshima and Nagasaki were a gun type fission weapon and a implosion bomb with a plutonium core respectively.

Little Boy

Little Boy was a nuclear fission bomb of uranium. It was dropped on Hiroshima in Japan. The bomb was loaded on to the B-29 bomber, Enola Gay. "Little Boy" measured nearly 14 feet long and 5 feet wide. Enola Gay was followed by 2 more B-29s carrying scientists to observe the explosion. The Enola Gay was flown by Colonel Paul Tibbetts.

Fat Man

Picture
Fat Man was a implosion bomb with a plutonium core. It was dropped on Nagasaki in Japan. This attack could have been prevented because Truman issued a warning. But, the Japanise were strong, and did not surrender though thousands were killed. Then, three days after the first bomb was dropped, Major Charles Sweeney flew the Bockscar alnog with Fat Man over Japan. The plan was to bomb near-by Kokura was a primary target, but they moved to the secondary target of Nagasaki instead due to poor visibility and cloud coverage.

Modern Day Nuclear Weapons

    Many countries now control modern nuclear weapons. Intercontinental balistic missiles (ICBMs) are used  by countries such as the US, China, Russia, France, UK, India, Israeli, and many others.
