"THE ATOMIC BOMBING OF NAGASAKI
Nagasaki (August 9, 1945)
Events: Dawn of the Atomic Era, 1945

The next break in the weather over Japan was due to appear just three days after the attack on Hiroshima, to be followed by at least five more days of prohibitive weather. The plutonium bomb, nicknamed "Fat Man," was rushed into readiness to take advantage of this window. No further orders were required for the attack. Truman's order of July 25th had authorized the dropping of additional bombs as soon as they were ready. At 3:47 a.m. on August 9, 1945, a B-29 named Bock's Car lifted off from Tinian and headed toward the primary target: Kokura Arsenal, a massive collection of war industries adjacent to the city of Kokura.
