Naval Facility (NAVFAC) Barbados, TWI, in commission 1957 to 1979, was the most southern of the Atlantic Sound Surveillance System (SOSUS) shore terminals. It had the distinction making the first system detection of a Soviet nuclear submarine in 1962 as that submarine was transiting off Norway. The facility was located adjacent to the Harrison Point Lighthouse, Parish of Saint Lucy. Since decommissioning the remaining structures have been put to use by the government of Barbados.
