In the month leading up to the Hiroshima bombing, the plane, still unnamed, flew eight practice missions and two regular bombing missions over Japan. The Navy turned it into a 40,000-person military base. The island, formerly under Japanese control and used as a sugar plantation, had been seized by U.S.
The plane arrived on the South Seas island of Tinian in July 1945.
The most famous war plane in history was built in 1945, as part of a batch of 15 Silverplate B-29 bombers specially modified for atomic bombing missions.
