The atomic bomb was dropped from the B-29, "Enola Gay", accompanied by two other B-29s:
one dropped a measuring and communication apparatus with a parachute on it, and another took photographs of the spreading atomic bomb cloud.
A heavy cruiser, the Indianapolis, carrying an atomic bomb, left San Francisco on July 16, 1945 and arrived at Tinian on 26th of the month, where the atomic bomb was loaded on the Enola Gay. The Indianapolis was, four days later, (July 30) torpedoed and sunk by a Japanese submarine west of Guam.
