Announced United States nuclear tests, July 1945-December 1983
This document lists chronologically and alphabetically by event name all nuclear tests conducted and announced by the United States from July 1945 through December 1983, with the exception of the GMX experiments. The 22 GMX experiments, conducted at the Nevada Test Site (NTS) between December 1954 and February 1956, were equation-of-state physics studies that used small chemical explosives and small quantities of plutonium. Several tests conducted during Operation Dominic involved missile launches from Johnston Atoll. Several of these missile launches were aborted, resulting in the destruction of the missile and nuclear device either on the pad or in the air. On August 5, 1963, the United States and the Soviet Union signed the Limited Test Ban Treaty which effectively banned testing of nuclear weapons in the atmosphere. All US nuclear tests conducted prior to that date have been announced and are listed in this document. Some tests conducted underground since the signing of the Treaty and designed to be contained completely have not been announced. Information concerning these events is classified. Occasionally, the name and detonation date of an unannounced test is declassified which permits its listing in subsequent revisions to this document. Data on United States tests were obtained from and verified by the Department of Energy's three weapons laboratories - Los Alamos National Laboratory, Los Alamos, New Mexico; Lawrence Livermore National Laboratory, Livermore, California; and Sandia National Laboratories, Albuquerque, New Mexico. Additionally, data were obtained from public announcements issued by the Atomic Energy Commission and its successors, the Energy Research and Development Administration and the Department of Energy, respectively.
