Glomar Challenger
''Glomar Challenger'' was a deep sea research and scientific drilling vessel for oceanography and marine geology studies. The drillship was designed by Global Marine Inc. (now Transocean Inc.) specifically for a long term contract with the American National Science Foundation and University of California Scripps Institution of Oceanography and built by Levingston Shipbuilding Company in Orange, Texas. Launched on March 23, 1968, the vessel was owned and operated by the Global Marine Inc. corporation.

Glomar Explorer
''GSF Explorer'', formerly USNS ''Hughes Glomar Explorer'' (T-AG-193), was a deep-sea drillship platform built for Project Azorian, the secret 1974 effort by the United States Central Intelligence Agency's Special Activities Division to recover the Soviet submarine ''K-129''. Construction The ship was built as ''Hughes Glomar Explorer'' in 1971 and 1972 by Sun Shipbuilding and Drydock Co. for more than (about $ billion in ) at the direction of Howard Hughes for use by his company, Global Marine Development Inc. It began operation on 20 June 1974. Hughes told the media that the ship's purpose was to extract manganese nodules from the ocean floor. This marine geology cover story became surprisingly influential, causing many others to examine the idea. Project Azorian The Soviet diesel-electric submarine ''K-129'' sank in the Pacific Ocean NW of Hawaii, on 8 March 1968. The USS ''Halibut'' identified the wreck site and the CIA crafted an elaborate and highly secret plan to ...
