LE2 Chronology 1962 October 16 - 09:14 GMT - Launch Vehicle: Delta. Thor DSV-2E 156 FAILURE: At 86 seconds after launch a booster failure occurred and the missile began tumbling. BLUEGILL DOUBLE PRIME Nuclear test Agency: USAF. 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 November 1 - 11:54 GMT - Launch Vehicle: Delta. Thor DSV-2E 226 KINGFISH Nuclear test Agency: USAF. 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. 1964 April 21 - 06:15 GMT - Launch Vehicle: Delta.
