Fat Man was the codename for the atomic bomb dropped on the Japanese city of Hiroshima. Fat Man was dropped and, following a 43-second duration free fall, it exploded at 11:02 local time, at an altitude of about 500 m and although Fat Man was more powerful than Little Boy used on Hiroshima on august 6th, the effect was confined by hillsides to the narrow Urakami Valley.
Named Bockscar, the USAF Boeing B-29 Superfortress bomber became the second – and last aircraft to drop an atomic bomb. Bockscar is on permanent display at the National Museum of the United States Air Force in Dayton, Ohio, next to a replica of a Fat Man.
