Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress "Enola Gay":
Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Planet War II and the 1st bomber to home its crew in pressurized compartments. Although created to fight in the European theater, the B-29 identified its niche on the other side of the globe. In the Pacific, B-29s delivered a range of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.
On August six, 1945, this Martin-constructed B-29-45-MO dropped the first atomic weapon employed in combat on Hiroshima, Japan. 3 days later, Bockscar (on show at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Wonderful Artiste, flew as an observation aircraft on each missions.
