Alaska Communications System
The Alaska Communications System (ACS), also known as the Washington-Alaska Military Cable and Telegraph System (WAMCATS), was a system of cables and telegraph lines authorized by the U.S. Congress in 1900 and constructed by the U.S. Army Signal Corps. The communications lines were to serve both military and civilian needs in the territory of Alaska. By 1904, ACS comprised some of undersea cable, over of land lines, and a wireless segment across at least . On May 15, 1936 WAMCATS was renamed the U.S. Army Alaska Communications System. The Alaska Communications System remained under the control of the Army Signal Corps until 1962 when it was taken over by the U.S. Air Force. The ACS handled the radioteletype, radio telephone, 500 kHz ship-to-shore frequencies, collected communications intelligence, and other services for more than half a century in Alaska. The Army Signal Corps (which develops, tests, provides, and manages communications and information systems support for the com ...

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

World War II American Electronics
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In '' scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Radio Systems Of The United States
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Telecommunications In The United States
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Communications In Alaska
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a universal phenomenon and a specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions. An important distinction is between verbal communication, which happens through the use of a language, and non ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Billy Mitchell (Chugach Mountains)
Mount Billy Mitchell is a prominent peak located in the Chugach Mountains, east of Valdez and west of the Copper River in the U.S. state of Alaska. This mountain forms a prominent and easily visible landmark between mile markers 43 and 51 of the Richardson Highway, as the highway passes just to its west between Tonsina and the Thompson Pass (see photograph). Mount Billy Mitchell was named for William "Billy" Mitchell (18791936), a brigadier general of the United States Army Air Service who is often referred to as the "father of the United States Air Force". Naming In response to the Klondike Gold Rush, the United States Army established numerous military outposts throughout the District of Alaska. As a lieutenant in the United States Army Signal Corps, Mitchell was stationed in Alaska at that time. On May 26, 1900, the United States Congress appropriated $450,000 in order to establish a communications system to connect the many isolated and widely separated U.S. Army ...

USS Thor
USS ''Thor'' was a cable repair ship that supported Project Caesar, the unclassified name for installation of the SOSUS, Sound Surveillance System (SOSUS). Originally the ''Vanadis'' (AKA-49) which was briefly in commission from 9 July 1945 to 27 March 1946, it was converted in 1955 after nine years in the reserve fleet. ''Thor'', named after the Thor, Germanic god of thunder, was commissioned on 3 January 1956 and served in that capacity until 2 July 1973 when transferred to the Military Sealift Command (MSC) for brief operation as USNS ''Thor'' (T-ARC-4) until April 1974 when the ship was returned to the Maritime Administration for disposal. After removal of cable machinery the ship was eventually sold for scrap on 22 September 1977. ''Thor'' was one of four Navy cable ships supporting military cable projects from the 1950s until 1984 with construction of . The others were , the other transport conversion, and the two Army designed cable ships, the only ships in the Navy desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mine Planter (vessel)
Mine planter and the earlier "torpedo planter" was a term used for mine warfare ships into the early days of World War I. In later terminology, particularly in the United States, a mine planter was a ship specifically designed to install controlled mines or contact mines in coastal fortifications. This type of ship diverged in both function and design from a ship operating as a naval minelayer. Though the vessel may be seagoing it is not designed to lay large numbers of mines in open sea. A mine planter was designed to place controlled minefields in exact locations so that they might be fired individually or as a group from shore when observers noted a target to be at or near a designated mine's position. The terms and types of specialized ship existed from the 1860s where "torpedoes" were made famous in the American Civil War until the demise of large, fixed coastal fortifications brought on by the changes of World War II. History and terminology The earliest naval mines were the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Nashawena (AG-142)
USS ''Nashawena'' (AG-142/YAG-35) was a U.S. Navy cable layer constructed during World War II for the Army as the wooden-hulled self-propelled barge BSP 2008. The barge was completed converted to cable work for U.S. Army Signal Corps as the cable ship ''Col. William. A. Glassford'' supporting the Alaska Communications System in the shallow island waters of Alaska.The "prefix" USASPB associated with the vessel is an error. The Army's designation of self propelled barges was Barge, Self Propelled (BSP). Smaller vessels simply had the designation "U.S. Army" and a number without being named. Some vessels were named but also bore the usual Army identification. The use can be seen in thiphoto of ''Col. William. A. Glassford''in which "U.S. Army" is followed by "B.S.P. 2008" with ''Glassford'' underneath on the hull. She was transferred to the U.S. Navy in 1947 as a miscellaneous auxiliary and assigned to cable-laying duties for the U.S. Pacific Fleet. The ship was sold to commercial int ...
