- Nth_Country_Experiment abstract "The Nth Country Experiment was an experiment conducted by Lawrence Livermore National Laboratory starting in May 1964 which sought to assess the risk of nuclear proliferation. The experiment consisted in paying three recent young physicists who had just received their PhDs, though had no prior weapons experience, to develop a working nuclear weapon design using only unclassified information, and with basic computational and technical support. "The goal of the participants should be to design an explosive with a militarily significant yield", the report on the experiment read, "A working context for the experiment might be that the participants have been asked to design a nuclear explosive which, if built in small numbers, would give a small nation a significant effect on their foreign relations."The experiment ended on April 10, 1967, after only three man-years of work over two and a half calendar years. According to a heavily redacted declassified version of the summary, it was apparently judged by lab weapons experts that the team had come up with a credible design for the technically more challenging implosion style nuclear weapon. It is likely that they would have been able to design a simpler gun combination weapon even more quickly, though in such a case the limiting factor in developing such a weapon is not usually design difficulty but rather the procurement of material (enriched uranium). The term "Nth Country" referred to the goal in assessing the difficulty in developing basic weapons design (again, not the same thing as the development of weapons themselves) for any potential country with a relatively small amount of technical infrastructure—if the United States was the 1st country to develop nuclear weapons, and the USSR the 2nd, and so on, which would be the Nth country?Due to the increased amount of publicly available resources regarding nuclear weapons, it is reasonable to assume that a viable weapon design could be reached with even less effort today. However in the history of nuclear weapons, the development of fission weapons was never strongly hindered by basic design questions except in the very first nuclear weapons programs. The Summary Report of the Nth Country Experiment was declassified—though heavily excised—in 2003.".
