was dropped on Nagasaki, Japan, on this date in 1945. The BBC provides some facts (the first two are as reported at the time of the bombing):
The bomb was dropped by parachute from an American B29 Bomber at 1102 local time.
It exploded about 1,625 ft (500m) above the ground and is believed to have completely destroyed the city, which is situated on the western side of the Japanese island of Kyushu.
About 30% of Nagasaki, including almost all the industrial district was destroyed by the bomb and nearly 150,000 people were killed or injured.
The bomb, nick-named “Fat Man” in a reference to Winston Churchill, measured just under 3.5m (11ft 4in) in length, had the power of 22 kilotons of TNT and weighed 4,050kg (9,000lbs).
Residents of both cities are still suffering the physical and mental consequences of radiation to this day.
On 14 August Japan surrendered to the Allies.
