Cockburn Town in Grand Turk, Turks and Caicos Islands, British Overseas Territories — North Atlantic Ocean
U.S. Naval Facility
Grand Turk
Known officially as the U.S. Facility for Oceanographic Research, the base was established to improve knowledge of oceanographic and acoustic conditions. The U.S. had found during World War II a need to improve knowledge of ocean conditions in order to better deal with enemy submarines. After the establishment of the facility, U.S. atomic submarines frequently sailed off Grand Turk.
Another U.S. facility, the Guided Missle Base, was constructed on the island's southern end at around the same time. The number of American personnel and families resident in the island at one time exceeded three hundred.
On March 31, 1980, the U.S. Facility for Oceanographic Research was officially closed and turned over to the Turks and Caicos Islands Government. The facility currently serves as the Grand Turk Community College.

2. U.S. Naval Facility 1958 at the gate
That's me at the watch gate while waiting for my clearance to come thru. After clearance came thru I worked down the hill in the Quonset hut where the sonar men worked and with their advanced equipment could detect Russian submarines 1500 miles away and could tell how many rpms their propellers were turning. When spotting a target they put the info and location of the target thru a slot that dropped into the crypto room where I worked and we encrypted the information and sent it forward to Norfolk, Va. The work was classified secret at the time and was later upgraded to top secret. That was 56 years ago.
Regarding U.S. Naval Facility. Historically, the term hydrography has meant the scientific study of the physical conditions of systems of water. Within the field of physical oceanography, hydrography is the branch of our field which looks to understand the movements of the ocean through its measurable physical properties, including: temperature, salinity, and oxygen, and
chemical constituents such as phosphates, silicates, **CFC's, tritium and helium. ( Oregon State University )
