U.S. military bases NAVFAC Eleuthera The United States Naval Facility (NAVFAC) Eleuthera, Bahamas was a shore terminus and processing facility for the Sound Surveillance System (SOSUS) operated by the U.S. Navy to detect submarines. In 1951 a six element test array had been placed off shore to demonstrate the system's capability to detect submarines. After successful tests with a U.S. submarine a functional forty element array was installed in 1952 as one of a total of nine Atlantic systems ordered. Though it was the first array to be installed, it was last to get the operational shore terminal under Navy command when NAVFAC Eleuthera was commissioned on 1 September 1957. The facility had a complement of 150 officers and enlisted men, a resident Western Electric engineer, some nineteen Pan-American Airway and RCA contractors and 45 Bahamian employees supported the facility. NAVFAC Eleuthera was decommissioned 31 March 1980 after 23 years of service. It was located near Governor's Harbour Airport. The first U.S. Navy women to be assigned to a SOSUS facility were the eleven assigned to NAVFAC Eleuthera in 1972. Seventeen years earlier the Canadian contingent of the joint U.S./Canadian Forces SOSUS facility, Canadian Forces Station (CFS) Shelburne, included five women of the Women's Royal Canadian Naval Service. Adjacent to the NAVFAC was the original site of the first experimental array and electronics, operated by two Western Electric engineers and a few military personnel, which continued in service as an avenue for experiments.
