Atomic Bombing of Hiroshima

On August 6, 1945, the United States dropped an atomic bomb named "Little Boy" on the Japanese city of Hiroshima. The B-29 bomber Enola Gay, piloted by Colonel Paul Tibbets, delivered the uranium bomb which detonated with an explosive force of about 15 kilotons of TNT. The bombing, which killed an estimated 80,000 people instantly and tens of thousands more from radiation exposure and injuries, marked the first use of nuclear weapons in warfare.
