Trinity Site


At 05:29:45 (Mountain War Time) on July 16, 1945, the human race entered the Atomic Age. Trinity was the first detonation of a nuclear device in history, as a precursor to using the device in combat.

On August 6, 1945, a B-29 Superfortress dropped a nuclear device code-named “Little Boy,” on Hiroshima, Japan.  Three days later, on August 9, 1945, another device, named “Fat Man,” was detonated over Nagasaki, Japan.
