Bythe Germans were ahead in the race for the atomic bomb. They had a heavy-water plant, high-grade uranium compounds, capable scientists and engineers, and the greatest chemical engineering industry in the world. Even before its entry into the war, the United States had become very concerned with the nuclear threat of the Axis powers.
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.

Private corporations, foremost among them DuPont, helped prepare weapons-grade uranium and other components needed to make the bombs. 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.

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.

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 Manhattan Project was the US government program during World War II that developed and built these first atomic bombs.
Detonation of these first nuclear bombs signaled arrival of . The Manhattan Project produced plutonium in nuclear reactors at the Hanford Engineer Works near Hanford, other personnel arrived at the Trinity Site to help prepare for the bomb test.
including Trinity and the atomic bombing of Japan. The atomic bomb project thus became known as the Manhattan Engineer District (MED), or Manhattan Project for short. Its first major funding came in December, when President Roosevelt ordered an initial allotment of $ million.
The Manhattan Project and the Second World War, In the early morning hours of August 6, , a B bomber named Enola Gay took off from the .
Security was a way of life for the Manhattan Project. The goal was to keep the entire atomic bomb program secret from Germany and Japan.
In this, Manhattan Project security officials succeeded. They also sought, however, to keep word of the atomic bomb from reaching the Soviet Union.
