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...

Nation: USA. Agency: AEC. Apogee: 147 km (91 mi). Test of the Los Alamos XW-50X1 60 kiloton nuclear warhead. Launch vehicle was a solid propellant XM-33 Strypi rocket with a Recruit booster stage. The warhead detonated at an altitude of 147 km, 66 km from Johnston Island. Observers on the island saw a green and blue circular region surrounded by a red ring. This faded in less than a minute. Blue-green streamers and pink striations developed that lasted half an hour. At this yield, even with the high altitude, extensive disruption of communications were not reported.
