The Armed Forces Special Weapons Project (AFSWP) was a United States military agency responsible for those aspects of nuclear weapons that remained under military control after the Manhattan Project was succeeded by the Atomic Energy Commission on 1 January 1947. These included the maintenance, storage, security and handling of nuclear weapons, and support for nuclear weapons testing. Early nuclear weapons were complex and cumbersome, and stored as components rather than complete devices due to the short shelf life of their lead-acid batteries and modulated neutron initiators, and the heat generated by the fissile cores. As nuclear weapons development proceeded, mass-produced models became available that were easier to store, handle, maintain and assemble, and the AFSWP became more involved in stockpile management, and providing administrative, technical and logistical support. In 1959, the AFSWP became the Defense Atomic Support Agency (DASA), a field agency of the Department of Defense. (Full article...)
