The First Atomic Test


On Monday morning July 16, 1945, the world was changed forever when
the first atomic bomb was tested in an isolated area of the New Mexico
desert. Conducted in the final month of World War II by the top-
secret Manhattan Engineer District, this test was code named Trinity.
The Trinity test took place on the Alamogordo Bombing and Gunnery
Range, about 230 miles south of the Manhattan Project's headquarters
at Los Alamos, New Mexico. Today this 3,200 square mile range, partly
located in the desolate Jornada del Muerto Valley, is named the White
Sands Missile Range and is actively used for non-nuclear weapons
testing.
