Bockscar - Atomic Bomb Mission

Atomic Bomb Mission

Bockscar was flown on August 9, 1945, by the crew of another B-29, The Great Artiste, and piloted by Major Charles W. Sweeney, commander of the 393d BS. The plane was co-piloted by 1st Lt. Charles Donald Albury, the normal aircraft commander of Crew C-15. The Great Artiste was designated as the observation, instrumentation support plane for the second mission, and another B-29, The Big Stink, flown by Group Operations Officer Major James I. Hopkins, Jr., as the photographic aircraft. The mission had as its primary target the city of Kokura, Japan, and as its only secondary, Nagasaki.

Bockscar had been flown by Sweeney and crew C-15 in three test drop rehearsals of inert "Fat Man" assemblies in the eight days leading up to the second mission, including the final rehearsal the day before. The Great Artiste, which was the assigned aircraft of the crew with whom Sweeney most often flew, had been designated in preliminary planning to drop the second bomb, but it had been fitted with observation instruments for the Hiroshima mission. Moving the instrumentation from The Great Artiste to Bockscar would be a complex and time-consuming process, and when the second atomic bomb mission was moved up from August 11 to August 9 because of adverse weather forecasts, the crews of The Great Artiste and Bockscar instead exchanged aircraft. The result was that the bomb was carried by Bockscar but flown by the crew C-15 of The Great Artiste.
