The atomic bomb on "Hiroshima"

Hiroshima is best remembered as the first city targeted by a nuclear weapon when the United States Army Air Forces (USAAF) dropped the atomic bomb "Little Boy" on the city at 8:15 a.m. on August 6, 1945. Most of the city was destroyed, and by the end of the year 90,000–166,000 had died as a result of the blast and its effects. The Hiroshima Peace Memorial (a UNESCO World Heritage Site) serves as a memorial of the bombing.
