On Aug. 9, 1945, the B-29 Bockscar dropped the ''Fat Man'' atomic bomb on Nagasaki, which led to Japan's unconditional surrender and the end of World War II.
"Bockscar", piloted Major Charles Sweeney, dropped the "Fat Man" atomic bomb on Nagasaki on Aug. 9, 1945, just three days after the atomic attack against Hiroshima, Japan. Bockscar was part of the same squadron as the Enola Gay, the B-29 Superfortress that dropped the first atomic bomb.
The B-29 had a cruising speed of 220mph and a maximum speed of 357mph. Bockscar was also one of 15 "Silverplate" B-29s with extensive modifications which allowed them to carry nuclear weapons. While most B-29s carried eight .50-cal. machine guns in remote controlled turrets, two .50-cal. machine guns, one 20mm cannon in a tail turret, and up to 20,000 pounds of bombs, Silverplate B-29s retained only the tail turret and had their armor removed to save weight so the heavy atomic bombs could be carried over longer distances.
Originally delivered to the United States Army Air Forces on 19 March, 1945 at a cost of $639,000, the name "Bockscar" was a pun on the name of aircraft commander Captain Frederick C. Bock who was assigned to aircraft. The Bockscar was flown to the museum on Sept. 26, 1961 and is now on permanent display in the World War II gallery.
