Class Notes:
Deep sea mining ship named HUGHES GLOMAR EXPLORER with Global Marine Inc. listed as owner 24 Jul 1973. ABS 1977 showed Summa Corp (Hughes' company) as her registered owner under Global Marine, Inc. This was all cover for a clandestine CIA operation, Project Azorian, to salvage the Soviet Project 629 (Golf-class) diesel-powered ballistic missile submarine K 129 that sank in 16,500 feet depth in 1968. The salvage attempt took place in August 1974 but only the foremost 38 feet of the submarine were recovered. For full details on the project see Project AZORIAN, the CIA and the Raising of the K-129, by Norman Polmar and Michael White (Naval Institute Press, 2010).
