Nuclear technology the element plutonium possesses an isotope that is sufficiently unstable for this process to be usable. Terrestrial plutonium does not currently occur naturally in sufficient quantities for such use, so it must be manufactured in a nuclear reactor. Ultimately, the Manhattan Project manufactured nuclear weapons based on each of these elements. They detonated the first nuclear weapon in a test code-named "Trinity", near Alamogordo, New Mexico, on July 16, 1945. The test was conducted to ensure that the implosion method of detonation would work, which it did. A uranium bomb, Little Boy, was dropped on the Japanese city Hiroshima on
B57 nuclear bomb Sea King. The B57 was also deployed with Canada's CF-104s in Germany, and the Royal Air Force's Nimrod from RAF St Mawgan and RAF Kinloss in the United Kingdom and Malta in the Mediterranean. B57 nuclear bomb The B57 nuclear bomb was a tactical nuclear weapon developed by the United States during the Cold War. Entering production in 1963 as the Mk 57, the bomb was designed to be dropped from high-speed tactical aircraft. It had a streamlined casing to withstand supersonic flight. It was 3 m (9 ft 10 in) long, with a diameter of about 37.5 cm (14.75
