Operation Totem status, the British government restarted its own development effort, which was given the cover name "High Explosive Research". The first British atomic bomb was tested in Operation Hurricane at the Montebello Islands in Western Australia on 3 October 1952. The main purpose of the trial was to determine the acceptable limit on the amount of plutonium-240 which could be present in a bomb. The plutonium used in the original Hurricane device was produced in the nuclear reactor at Windscale, but the Windscale Piles did not have anything like the capacity to provide sufficient material for the British government's planned weapons
Redstone Test Stand in tests to study the effects of nuclear detonations in the upper atmosphere, Operation Hardtack I. After being static-fired at the Interim Stand in January 1958, two missiles were shipped to the Pacific Test Range. In July and August, the missiles became the first missiles ever to detonate atomic warheads. In 1958, Redstone development ended and Chrysler began mass production for deployment. Only a few of these missiles were tested at the Interim Test Stand because the propulsion system had become so reliable. As the space race continued, the civilian space agency, NASA started on October 1, 1958 but the
