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
Propane bomb timer or remote detonation. The expanding gas of the ignited propane bursts the shell of the tank and causes the explosion, similar to the fundamentals of a pressure cooker bomb or a pipe bomb. The 1983 Beirut barracks bombings murdered 305 U.S. and French peacekeepers during the Lebanese Civil War with two truck bombs. The explosive mechanism was a gas-enhanced device consisting of compressed butane in canisters employed with Pentaerythritol tetranitrate to create a fuel-air explosive. The bomb was carried on a layer of concrete covered with a slab of marble to direct the blast upward. Despite the lack of
