Making the Atomic Bomb Part V: The Atomic Bomb and American Strategy Hiroshima In the early morning hours of August 6,a B bomber attached to the th Composite Group took off from Tinian Island and headed north by northwest toward the Japanese Islands over 1, miles away.
Overview The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki in Augustkillingpeople—children, women, and men.
In the days following the bombings Japan surrendered. Detonation of these first nuclear bombs signaled arrival of a frightening new Atomic Age. President Franklin Roosevelt created a committee to look into the possibility of developing a nuclear weapon after he received a letter from Nobel Prize laureate Albert Einstein in October In his letter, Einstein warned the president that Nazi Germany was likely already at work on developing a nuclear weapon.
By Augustthe Manhattan Project was underway.
Albert Einstein and J. Einstein warned that the Germans were researching an atomic bomb and suggested that the United States do the same. Oppenheimer was the leading scientist at Los Alamos National Laboratory.

Nuclear materials were processed in reactors located in Oak Ridge, Tennessee and Hanford, Washington. At its peak, the Manhattan Project employedAmericans at thirty-seven facilities across the country. On July 16, the first nuclear bomb was detonated in the early morning darkness at a military test-facility at Alamogordo, New Mexico.
House windows more than fifty miles away shattered. Hiroshima and Nagasaki In Maythe Allies defeated Germanytwo months before the atomic bomb was complete.
War with Japan continued, however, and In August it seemed that an invasion of Japan itself might be necessary to force the Japanese to surrender. Military advisers to President Harry S. Truman warned that such a ground war would result in the deaths of tens or hundreds of thousands of young men in the US Armed Forces, as well as the deaths of many Japanese military personnel and civilians.
After receiving no reply to his threat that "prompt and utter destruction" would follow if the Japanese did not surrender unconditionally, Truman authorized the use of the bomb on Japan.
The device exploded over the city with a force of 12, tons of TNT. Aboutpeople were killed instantly or died due to injury or radiation poisoning within months of the blast at Hiroshima.The Seattle Times has created one of the definitive sites examining the development of the atomic bomb.
The Manhattan Project, which included some of history's greatest scientific minds, lead to the end of the war against the Japanese.

The Manhattan Project: Making the Atomic Bomb "The Manhattan Project: Making the Atomic Bomb" is a short history of the origins and development of the American atomic bomb program during World War II.
Jul 26, · The Manhattan Project was the code name for the American-led effort to develop a functional atomic weapon during World War II. The controversial creation and eventual use of the atomic bomb.
The Manhattan Project was a code name of an effort started in late to design and build the atomic bomb. In , Einstein and other scientists urged the American Government to start building an atomic bomb when they heard that German physicists had discovered the secrets of splitting uranium atoms.
