Naval Facility Bermuda
Naval Facility Bermuda, or NAVFAC Bermuda, was the operational shore terminus for one of the Atlantic SOSUS, 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 operational surveillance facility was often confused with the adjacent research facility, the Tudor Hill Laboratory, and its undersea sensors supporting research and development for Navy acoustic systems. That laboratory was the only such research and development facility with access to an operational surveillance facility. When that laboratory, then a detachment of the Naval Undersea Warfar ...

Naval Facility Bermuda & Tudor Hill Laboratory
A navy, naval force, military maritime fleet, war navy, or maritime force is the military branch, branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launche ...

Watch Floor
A watch is a timepiece carried or worn by a person. It is designed to maintain a consistent movement despite the motions caused by the person's activities. A wristwatch is worn around the wrist, attached by a watch strap or another type of bracelet, including metal bands or leather straps. A pocket watch is carried in a pocket, often attached to a chain. A stopwatch is a type of watch that measures intervals of time. During most of their history, beginning in the 16th century, watches were mechanical devices, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are known as ''mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, powered by a battery and keeping time with a vibrating quartz crystal. By the 1980s it had taken over most of the watch market, in what became known as the quartz revolution (or the quartz crisis in Switzerland, whose renowned watch industry it decimated). In the ...

Southampton Parish, Bermuda
Southampton Parish is one of the nine parishes of Bermuda. It is named for Henry Wriothesley, 3rd Earl of Southampton Henry Wriothesley, 3rd Earl of Southampton, (pronunciation uncertain: "Rezley", "Rizely" (archaic), (present-day) and have been suggested; 6 October 1573 – 10 November 1624) was the only son of Henry Wriothesley, 2nd Earl of Sou ... (1573-1624). It is located in the southwest of the island chain, occupying all of the western part of the main island, except for the westernmost tip (which is part of Sandys Parish). It includes the chain's southernmost point, and its north coast comprises much of the coast of the Little Sound (an arm of the Great Sound, the large expanse of water which dominates the geography of western Bermuda). in the east it is joined to Warwick Parish. As with most of Bermuda's parishes, it covers just over 2.3 square miles (about 6.0 km2 or 1500 acres). It had a population of 6,421 in 2016. Natural features in S ...

Fortifications In Bermuda
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted as a border gu ...

Military Of Bermuda
While the defence of Bermuda remains the responsibility of the government of the United Kingdom, rather than of the local Bermudian Government, the island still maintains a militia for the purpose of defence. History The defence of the colony against an expected Spanish attack was the first concern of the first Governor of Bermuda, Richard Moore, when he and fifty-one other settlers arrived at Bermuda aboard the Plough on the 11 July 1612, to join the three men left behind in Bermuda from the 1609 wreck of the Sea Venture. The construction of fortified coastal artillery batteries was consequently prioritised over other construction, with the artillery manned by volunteers (convicted criminals were also sometimes sentenced to serve in the batteries instead of imprisonment). A militia was also raised on the lines of the militia in England, which grew to a battalion composed of nine companies (one for each parish). All fit males between the ages of 16 and 60, whether free, indentur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USN NAS Bermuda, Kindley Field, 1970-1995
Naval Air Station Bermuda was a United States Navy establishment in the then British Colony of Bermuda from 1940 to 1995. It operated from several locations and under different names during this period. At first, as the Naval Operating Base, it was located on Darrell’s Island, in Great Sound, before moving in 1941 to a new site on Tucker and Morgan Islands in the West End. In the 1960s, as the Naval Air Station, it moved to Kindley Field, the US Army Air Force base on St David's Island in Castle Harbour, while the West End site became the Bermuda Annex. After closure in 1995 the base became the site of Bermuda International Airport. History Prior to American entry into the Second World War, an agreement was arranged between the governments of British Prime Minister Winston Churchill and U.S. President Franklin D. Roosevelt for the loan of a number of obsolete, mothballed ex-US Naval destroyers to the Royal Navy and the Royal Canadian Navy, in exchange for which the USA ...

Argus Island
Argus Island was an acoustics, acoustic research tower and platform located on Plantagenet Bank, a guyot about 30 miles southwest of the island of Bermuda. The tower was originally part of the facilities supporting Project Artemis and Project Trident under auspices of the Naval Facility Bermuda, Tudor Hill Laboratory, a facility of the US Navy's Naval Undersea Warfare Center, Underwater Sound Laboratory.The Tudor Hill Laboratory and Argus Island were acoustic research and development facilities not a part of the Sound Surveillance System (SOSUS). The laboratory was adjacent to the Naval Facility (NAVFAC) Bermuda and was the only Atlantic R&D laboratory with access to an operational SOSUS facility. As a result, partly due to cover story of the NAVFAC as "oceanographic research" the two were often associated and confused as a single entity. Later the tower was used for additional acoustic experiments as well as oceanographic observations, wave height measurements, optical observations, ...

Project Artemis
Project Artemis was a United States Navy acoustics research and development experiment from the late 1950s into the mid 1960s to test a potential low-frequency active sonar system for ocean surveillance. The at sea testing began in 1960 after research and development in the late 1950s. The project's test requirement was to prove detection of a submerged submarine at . The experiment, covering a number of years, involved a large active element and a massive receiver array. The receiving array was a field of modules forming a three dimensional array laid from 1961 to 1963 on the slopes of a seamount, the Plantagenet Bank (), off Bermuda. The modules, attached to ten lines of cable, were masts with floats on top to keep them upright. Each module mounted sets of hydrophones. The receiving array terminated at Argus Island, built on the seamount's top, with data processed at the laboratory that was also constructed for the project. The laboratory was then the Naval Facility Bermuda#T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Frequency Analyzer And Recorder (LOFAR)
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. Both the equipment and process had specific and classified application to fixed surveillance sonar systems and was the basis for the United States Navy's ocean wide SOSUS, Sound Surveillance System (SOSUS) established in the early 1950s.
