Type: Suborbital Launch Site. Operator: USA. Country: USA. Latitude: 16°44'15" N. Longitude: 169°31'26" W.

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.

  • 1962 June 4 09:44 - BLUEGILL Nuclear Test mission Launch Vehicle: Thor DSV-2E. Thor DSV-2E 199 LC: LE1. Apogee: 500 km (310 mi). Initial attempt to launch a live nuclear weapon using the Thor IRBM from Johnston Atoll. The range safety radar had been unreliable before launch,. Five minutes after launch, after shutdown of the booster, the Johnston missile tracking system failed. Unable to monitor the warhead's flight path, the range safety officer destroyed it 10 minutes later, prior to warhead detonation.

  • 1962 June 19 - Aeronomy mission Launch Vehicle: Nike-Cajun. Nike Cajun FB-2 Apogee: 100 km (60 mi).

  • 1962 June 20 08:46 - STARFISH Nuclear Test mission Launch Vehicle: Thor DSV-2E. Engine shut down after 59 seconds. Destroyed by range safety.. Thor DSV-2E 193 LC: LE1. Apogee: 10 km (6 mi).

  • 1962 July 9 08:46 - STARFISH PRIME Nuclear Test mission Launch Vehicle: Thor DSV-2E. Thor DSV-2E 195 LC: LE1. Apogee: 400 km (240 mi). Successful high-altitude test of a Thor IRBM with a live nuclear warhead. The payload included test instrumentation and a W-49 warhead/Mk-4 re-entry vehicle. The 1.45 megaton bomb exploded at an altitude of 400 km. The explosion was visible 2,600 km away, at Kwajalein Atoll; an artificial aurora lasted seven minutes. The unforeseen and most militarily significant effect was the electromagnetic pulse (EMP) generated by the test. This caused power mains surges in Oahu, knocking out street lights, blowing fuses and circuit breakers, and triggering burglar alarms (and this in the days before microelectronics). The explosion supercharged the Van Allen radiation belts, resulting in several satellites malfunctioning.

  • 1962 July 19 08:40 - Aeronomy mission Launch Vehicle: Nike-Cajun. Nike Cajun FB-5 Apogee: 100 km (60 mi).

  • 1962 July 23 - Aeronomy mission Launch Vehicle: Javelin. Apogee: 500 km (310 mi).

Second attempt to launch a nuclear weapon using the Thor IRBM. The payload consisted of two re-entry vehicles, one with an instrument pod, the other with the warhead. The missile engine malfunctioned immediately on ignition. Range safety fired the destruct system whille the missile was still on the launch pad. The Johnston Island launch complex was heavily damaged and contaminated with plutonium. Three months of repairs and decontamination were necessary before tests could resume.

  • 1962 October 16 09:14 - BLUEGILL DOUBLE PRI Nuclear Test mission Launch Vehicle: Thor DSV-2E. At 86 seconds after launch a booster failure occurred and the missile began tumbling.. Thor DSV-2E 156 LC: LE2. Apogee: 10 km (6 mi). The third attempt to launch a nuclear warhead using a Thor IRBM. At 86 seconds after launch a booster failure occurred and the missile began tumbling. Range safety destroyed the errant booster at 156 seconds after launch. Some radioactive fallout from the warhead was detected on Johnston Atoll.

  • 1962 October 20 08:30 - CHECKMATE Nuclear Test mission Launch Vehicle: Castor-Recruit. 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.

  • 1962 October 20 09:00 - Aeronomy mission Launch Vehicle: Nike-Cajun. Nike Cajun FB-7 Apogee: 100 km (60 mi).

  • 1962 October 26 09:44 - BLUEGILL TRIPLE PRI Nuclear Test mission Launch Vehicle: Thor DSV-2E. Thor DSV-2E 141 LC: LE1. Apogee: 500 km (310 mi). On the fourth attempt, a Thor IRBM was used to launch a Mk 4 Re-entry Vehicle containing a 186 kg W-50 nuclear warhead of either 200 or 400 kilotons yield. The detonation occurred at an altitude of 50 km, 31 km SSW of Johnston Atoll. A fireball formed, the colourful afterglow continuing for 30 minutes of the explosion. At this altitude the extensive disruption of the ionosphere seen in later explosions did not occur.

  • 1962 November 1 11:54 - KINGFISH Nuclear Test mission Launch Vehicle: Thor DSV-2E. Thor DSV-2E 226 LC: LE2. Apogee: 500 km (310 mi). A Thor IRBM was used to launch a Mk 4 Reentry Vehicle containing a 186 kg W-50 nuclear warhead of either 200 or 400 kilotons yield. The detonation occurred at an altitude of 98 km, 69 km SSW of Johnston Atoll, and resulted in dramatic aurora-like effects visible as far away as Hawaii. More notably, the explosion had a massive effect on the ionosphere which disrupted radio communications over the entire central Pacific for three hours.
