The military defense of Puerto Rico is the responsibility of the United States as part of the Treaty of Paris. Locally, Puerto Rico has its own National Guard, the Puerto Rico National Guard, and its own state defense force, the Puerto Rico State Guard, which, by local law, is under the authority of the Puerto Rico National Guard. The commander-in-chief of both forces is the governor of Puerto Rico, currently Pedro Pierluisi, who delegates his authority to the Puerto Rico Adjutant General, currently Major General José J. Reyes. The Adjutant General, in turn, delegates the authority over the State Guard to another officer but retains the authority over the Puerto Rico National Guard as a whole. At the national level, the commander-in-chief is the President of the United States, currently Joe Biden.
Sound Surveillance System (SOSUS) was the original name for a submarine detection system based on passive sonar developed by the United States Navy to track Soviet submarines. The system's true nature was classified with the name and acronym SOSUS classified as well. The unclassified name Project Caesar was used to cover the installation of the system and a cover story developed regarding the shore stations, identified only as a Naval Facility (NAVFAC), being for oceanographic research. The name changed to Integrated Undersea Surveillance System (IUSS) in 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems. The commands and personnel were covered by the "oceanographic" term until 1991 when the mission was declassified. As a result, the commands, Oceanographic System Atlantic and Oceanographic System Pacific became Undersea Surveillance Atlantic and Undersea Surveillance Pacific, and personnel were able to wear insignia reflecting the mission.
Royal Air Force St Mawgan or more simply RAF St Mawgan is a Royal Air Force station near St Mawgan and Newquay in Cornwall, England. In 2008 the runway part of the site was handed over to Newquay Airport. The remainder of the station continues to operate under the command of the RAF. RAF St Mawgan used to have the widest military runway in the UK (300 ft) and was the home of the Cornwall Air Ambulance service and more recently 505 (Wessex) Squadron Royal Auxiliary Air Force (RAuxAF).

Naval Facility Bermuda, or NAVFAC Bermuda, was the operational shore terminus for one of the Atlantic Sound Surveillance System (SOSUS) array systems installed during the first phase of system installation and in commission from 1955 until 1992. The true surveillance mission was classified and covered by "oceanographic research" until the mission was declassified in 1991. The system's acoustic data was collected after the facility was decommissioned until the system was routed to the central processing facility, the Naval Ocean Processing Facility (NOPF), Dam Neck, Virginia in 1994.
The Puerto Rico Air National Guard(PR ANG) —Spanish: Guardia Nacional Aérea de Puerto Rico— is the aerial militia of the Commonwealth of Puerto Rico, an unincorporated territory of the United States of America. It is, along with the Puerto Rico Army National Guard and the Puerto Rico State Guard, an element of the Puerto Rico National Guard. After beginning as four units, the PRANG expanded to 11 units by the 1980s, including the 1956th Tactics Combat Group, the 140th Radar Squadron and others.
Naval Facility Nantucket Island or simply Naval Facility Nantucket was a shore terminal of the Sound Surveillance System (SOSUS) active from 1955 to 1976. The true function of the system and the shore terminals, in which output of the array at sea was processed and displayed by means of the Low Frequency Analyzer and Recorder (LOFAR), was classified and the term "Naval Facility" was intentionally vague. Its function was described as oceanographic research.
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.
Carlsen Air Force Base is a former United States Army Air Forces World War II airbase on Trinidad, consisting of two landing strips, "Edinburgh" and "Xeres". The airbase also included an emergency landing strip, "Tobago".
Beane Air Force Base was a United States Air Force base located near Vieux Fort, Saint Lucia, in the Caribbean Sea. It is now the site of Hewanorra International Airport.
The 141st Air Control Squadron (ACS) is a unit of the Puerto Rico Air National Guard. It is a mobile radar command, control and communications element of the United States Air Force Theater Air Control System located at Punta Borinquen Radar Station near by Rafael Hernandez Airport formerly Ramey Air Force Base in Aguadilla, Puerto Rico.
Canadian Forces Station (CFS) Shelburne is a former Canadian Forces Station that was a shore terminus for the Sound Surveillance System (SOSUS) from 1955 to 1994. It was located in the Municipality of the District of Shelburne, Shelburne County, Nova Scotia.
Fort Allen, officially Fort Allen Training Center, is a Puerto Rico National Guard military installation located on a 373-hectare (921-acre) facility in Juana Díaz, Puerto Rico.
Naval Air Facility Adak, was a United States Navy airport located west of Adak, on Adak Island in the U.S. state of Alaska. After its closure in 1997, it was reopened as Adak Airport. The facility was designated a National Historic Landmark for its role in World War II, although most of its elements from that period have been demolished or lie in ruins.
Naval Air Station Midway Island, also known as NAS Midway, Naval Air Facility Midway, and NAF Midway, was a U.S. Naval Air Station in the Midway Atoll, the northernmost group of the Hawaiian archipelago. It was in operation from 1941 to 1993, and played an important role in trans-Pacific aviation during those years. Through its lifetime, the facility was variously designated as a Naval Air Station, a Naval Air Facility, and a naval base. It was finally closed on 1 October 1993.
Punta Borinquén Radar Station is a facility of the Puerto Rico Air National Guard home for the 141st Air Control Squadron. Located adjacent to Rafael Hernández Airport, in Aguadilla, Puerto Rico. The facility has operated since 1964 when the 140th Aircraft Control and Warning Squadron (ACWS) was created under the control of Air Defense Command (ADC).
Naval Facility Cape Hatteras was a Sound Surveillance System (SOSUS) shore terminal, one of the nine initial systems installed, located on Cape Hatteras near Buxton, North Carolina and adjacent to the old location of the Cape Hatteras lighthouse. NAVFAC Cape Hatteras, eighth of the initial nine Atlantic systems to be activated, was in commission 11 January 1956 to 30 June 1982.
Naval Facility Point Sur was one of 30 secret sites worldwide that were built during the Cold War to detect Soviet submarines. In 1958, the U.S. Navy built a Naval Facility ½ mile south of Point Sur on the Big Sur coast to provide submarine surveillance using the classified SOund SUrveillance System (SOSUS). The public was told the station was engaged in oceanographic research.
In 1958 Naval Facility (NAVFAC) Centerville Beach was the third Sound Surveillance System (SOSUS) shore terminal, in which output of the array at sea was processed and displayed by means of the Low Frequency Analyzer and Recorder (LOFAR), established on the Pacific coast. The previous year the last of the original Atlantic systems, Naval Facility Barbados, had become operational and the first of the Pacific systems had been installed at San Nicolas Island. Naval Facility Point Sur to the south had been commissioned on 8 January 1958. The SOSUS mission, as well as the name itself was classified until 1991. The facility was installed under the cover name Project Caesar and described as being engaged in "oceanographic research" with its actual role in undersea surveillance not revealed until two years before the facility closed.
Low Frequency Analyzer and Recorder and Low Frequency Analysis and Recording (LOFAR) are the equipment and process respectively for presenting a visual spectrum representation of low frequency sounds in a time–frequency analysis. The process was originally applied to fixed surveillance passive antisubmarine sonar systems and later to sonobuoy and other systems. Originally the analysis was electromechanical and the display was produced on electrostatic recording paper, a Lofargram, with stronger frequencies presented as lines against background noise. The analysis migrated to digital and both analysis and display were digital after a major system consolidation into centralized processing centers during the 1990s.
