USS Saluda (YAG-87)
USS ''Saluda'' (IX-87) was a wooden-hulled, yawl-rigged yacht of the United States Navy. Service history U.S. Navy ''Saluda'' was assigned to the Port Everglades Section Base under the administrative control of the Commandant, 7th Naval District and remained there for outfitting. She was commissioned on 20 June 1943 and assigned to the Bureau of Ordnance for experimental work at the Underwater Sound Laboratory, at Fort Trumbull, New London, Connecticut. In December, she sailed south to St. Thomas, Virgin Islands, and thence proceeded to various Caribbean ports. In the spring of 1944 the vessel was used to test the theory developed by Maurice Ewing and J. Lamar Worzel of a SOFAR channel, or deep sound channel. A hydrophone was hung from ''Saluda'' to detect signals from a second ship setting off explosive charges up to miles away. Proof of the theory led to a development to use the SOFAR channel to locate downed air crews by detecting the explosion of a small charge close to th ...

Saluda River
The Saluda River is a principal tributary of the Congaree River, about 200 mi (320 km) long, in northern and western South Carolina in the United States. Via the Congaree River, it is part of the watershed of the Santee River, which flows to the Atlantic Ocean. Course The Saluda River is formed about 10 mi (15 km) northwest of the city of Greenville, on the common boundary of Greenville and Pickens Counties, by the confluence of its north and south forks, each of which rises in the Blue Ridge Mountains very near the border of North Carolina at Saluda, North Carolina: *The North Saluda River flows generally south-southwestwardly through northern Greenville County, past Marietta. *The South Saluda River flows generally southeastwardly on the Greenville-Pickens County border, receiving the Oolenoy River and the Middle Saluda River, which rises in Jones Gap State Park and flows generally southward through northwestern Greenville County.

3rd Naval District
The naval district was a U.S. Navy military and administrative command ashore. Apart from Naval District Washington, the Districts were disestablished and renamed Navy Regions about 1999, and are now under Commander, Naval Installations Command (CNIC). They were established for the purpose of decentralizing the Navy Department's functions with respect to the control of the coastwise sea communications and the shore activities outside the department proper, and for the further purpose of centralizing under one command: : (a) For military coordination, all naval activities, and : (b) For administrative coordination, all naval activities with specific exceptions, within the district and the waters thereof. The limits of the naval districts are laid down in article 1480, Navy Regulations. Those limits extend to seaward so far as to include the coastwise sea lanes (art. 1486 (1), Navy Regulations). "Each naval district shall be commanded by a designated commandant, who is the dir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unclassified Miscellaneous Vessels Of The United States Navy
Classified information is material that a government body deems to be sensitive information that must be protected. Access is restricted by law or regulation to particular groups of people with the necessary security clearance and need to know, and mishandling of the material can incur criminal penalties. A formal security clearance is required to view or handle classified material. The clearance process requires a satisfactory background investigation. Documents and other information must be properly marked "by the author" with one of several (hierarchical) levels of sensitivity—e.g. restricted, confidential, secret, and top secret. The choice of level is based on an impact assessment; governments have their own criteria, including how to determine the classification of an information asset and rules on how to protect information classified at each level. This process often includes security clearances for personnel handling the information. Some corporations and non-governm ...

Pacific Harbors Council
Scouting in Washington has a long history, from the 1910s to the present day, serving thousands of youth in programs that suit the environment in which they live. Early history (1910–1950) Camp Black Mountain, located on the beautiful shores of Silver Lake an hour drive east of Bellingham, is the oldest existing camp in Washington State. Interviews with Hugh Eldridge Carr and General Floyd Hansen, Bellingham Eagle Scouts from the early 1920s, indicate the camp was active prior to 1919. The land was used by permission of owner H. P. Jukes (the council treasurer) prior to transferring ownership to the BSA in 1927. It was originally used by the Bellingham Council as Camp H. P. Jukes and has been in continuous use since that time with the exception of two seasons during WWII (1943 and 1944). Upon first use the camp was used for troop and district events, but became a fully organized resort in 1925. During the 1920s, the camp was supported by the Order of the Blue Knot, an honor ca ...

Naval Vessel Register
The ''Naval Vessel Register'' (NVR) is the official inventory of ships and service craft in custody of or titled by the United States Navy. It contains information on ships and service craft that make up the official inventory of the Navy from the time a vessel is authorized through its life cycle and disposal. It also includes ships that have been removed from the register (often termed '' stricken'' or ''struck''), but not disposed of by sale, transfer to another government, or other means. Ships and service craft disposed of prior to 1987 are currently not included, but are gradually being added along with other updates. History The NVR traces its origin back to the 1880s, having evolved from several previous publications. In 1911, the Bureau of Construction and Repair published ''Ships Data US Naval Vessels'', which subsequently became the ''Ships Data Book'' in 1952 under the Bureau of Ships. The Bureau of Ordnance's ''Vessel Register'', first published in 1942 and retitl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Naval Electronics Laboratory
The U.S. Navy Electronics Laboratory (''NEL'') was created in 1945, with consolidation of the naval radio station, radar operators training school, and radio security activity of the Navy Radio and Sound Lab (NRSL) and its wartime partner, the University of California Division of War Research. NEL’s charter was “''to effectuate the solution of any problem in the field of electronics, in connection with the design, procurement, testing, installation and maintenance of electronic equipment for the U.S. Navy.''” Its radio communications and sonar work was augmented with basic research in the propagation of electromagnetic energy in the atmosphere and of sound in the ocean. History In November 1945, the Navy Radio and Sound Lab was renamed as Navy Electronics Laboratory. 80% of the Point Loma Military Reservation evolved into the Naval Electronics Laboratory Center (NELC) at the end of World War II. In turn NELC was merged into the Naval Ocean Systems Center (NOSC) in 1977. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thames Shipyard
The Old Thames Shipyard is a historic shipyard on the Thames River at the end of Farnsworth Street in New London, Connecticut. Established in 1900, the shipyard included, at the time of its listing on the National Register of Historic Places in 1975, a complete working steam-powered marine railway system, one of the few such in the nation. Description and history The Old Thames Shipyard is located on the Thames River waterfront in northern New London, just north of the United States Coast Guard Academy. It is accessed via Farnsworth Street, down a steep slope to the waterfront, and is set on basically level terrain between the river and a railroad right-of-way. The property (as of 1975) included a brick headhouse, from which three sets of rails descended into the river. Two steam engines powered heavy chain winches (with a capacity of 1000 and 4000 deadweight tons respectively) for hauling boats out of the water. It was built by Thomas Chappell, who operated a fleet of tugs an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
