1945: A U.S. Army Air Force B-29 bomber, called the Enola Gay, took off from North Field on the island of Tinian Island and later in the day dropped an atomic bomb on Hiroshima, Honshu, Japan. This was the first time that the weapon, until then held secret, was used for a military purpose. The bomb destroyed over four square miles of the city and brought death or injury to over 160,000 people. Seabees of the 6th Naval Construction Brigade participated in many phases of the operation. When the USS Indianapolis arrived at Tinian from the Naval Weapons Center, Port Chicago, California, Seabees helped with the unloading of the components of the atomic bomb. The Seabees then stored the elements in a shed built by themselves, and they then organized a detachment to guard the shed and its mysterious contents. Scientists assembled the atomic bombs in the shed with several Seabees assisting as handymen. Later, when she started on her mission to Japan, the Enola Gay with her atomic bomb took off from Tinian’s North field which the Seabees had built.
