Nuclear explosion debris. The first man made nuclear explosion occurred on July 16, 1945 at 5:50 am on the Trinity Test Site near Alamogordo, New Mexico in the United States, an area now known as the White Sands Missile Range. The event involved the full-scale testing of an implosion-type fission atomic bomb. In a memorandum to the U.S. Secretary of War, General Leslie Groves describes the yield as equivalent to 15,000 to 20,000 tons of TNT. Following this test, a uranium-gun type nuclear bomb (Little Boy) was dropped on the Japanese city of Hiroshima on August 6, 1945, with a blast yield
SC1000 bomb from the River Lea near Three Mills Island in London. The bomb was defused and the explosive liquefied and pumped out using steam by bomb disposal officers from the Royal Engineers before the bomb was destroyed in a controlled explosion after five days. In June 2013 an SC 1000 bomb was recovered from the Odra in central Szczecin, Poland. The area was evacuated while the bomb was lifted from the river by military engineers, and then taken in convoy to an Army training base near Drawsko Pomorskie to be destroyed in a controlled explosion. In early December an SC1000 bomb
