BOCKSCAR USAF B-29 BOMBER

Bockscar is a USAF B-29 bomber that dropped the Fat Man nuclear weapon over Nagasaki on August 9, 1945, the second atomic weapon used against Japan. Bockscar is a pun on boxcar after the name of its aircraft commander, Captain Frederick C. Bock.

Bockscar was built at the Glenn L. Martin Aircraft Plant at Omaha, Nebraska, as a Block 35 aircraft. It was one of ten modified as a Silverplate and redesignated Block 36. Delivered on March 19, 1945 to the USAF, it was assigned to Captain Frederick C. Bock and crew C-13.

Bockscar was also used in 13 training and practice missions from Tinian, and three combat missions in which it dropped pumpkin bombs on industrial targets in Japan. B29 aircraft is now on permanent display at the National Museum of the United States Air Force, Dayton, Ohio.
