Associated Launch Sites
  • Eniwetok Nuclear test sites. Sounding rockets were launched from here to monitor nuclear blast effects and fallout from 22 October 1957. Known to have been used for 7 launches from 1957 to 1958, reaching up to 5000 kilometers altitude. More...
  • Tonopah Sounding rocket and test vehicle launch site. Conducted launches in support of US nuclear weapons development programs. Known to have been used for 93 launches from 1957 to 1986, reaching up to 270 kilometers altitude. More...
  • Johnston Island US military base on this island in the Pacific Ocean. Used for rocket-launched nuclear tests in the 1950's. In the 1960's it was the site for the operational AFP-437 anti-satellite system. The system was retired in 1975. Several sounding rockets were also launched over the years, either in support of nuclear tests or in experiments related to anti-satellite technology. Known to have been used for 124 launches from 1958 to 1975, reaching up to 1158 kilometers altitude. More...
