Hiroshima and Nagasaki had been virtually untouched by the U.S. and Allied bombing runs. On August 6, 1945, at 9:15 AM Tokyo time, a B-29 plane, the "Enola Gay" piloted by Paul W. Tibbets, dropped a uranium atomic bomb, code named "Little Boy" on Hiroshima, Japan's seventh largest city.
Likewise, people ask, what was the codename for the plan to build the atomic bomb?
Manhattan Project. The Manhattan Project was the code name for America's atomic bomb development efforts during World War II. Its name originated from the fact that it was part of the U. S. Army Corps of Engineers and organized under the Manhattan Engineer District (MED) in New York City.
What was the name of the plane that dropped the first atomic bomb?
The bomb, nicknamed “Little Boy”, was dropped by the B-29 Superfortress bomber Enola Gay. And although it took a second atomic bomb to force Japan to surrender, the Enola Gay's name has gone down in history as the plane that was responsible for ending WWII. But the crew of the Enola Gay only dropped the first bomb.
Why did US drop a bomb on Japan?
President Harry S. Truman, warned by some of his advisers that any attempt to invade Japan would result in horrific American casualties, ordered that the new weapon be used to bring the war to a speedy end. On August 6, 1945, the American bomber Enola Gay dropped a five-ton bomb over the Japanese city of Hiroshima.
