Mine Planter (ship)
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] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ROTC
The Reserve Officers' Training Corps (ROTC ( or )) is a group of college- and university-based officer-training programs for training commissioned officers of the United States Armed Forces. Overview While ROTC graduate officers serve in all branches of the U.S. military, the U.S. Marine Corps, the U.S. Space Force, and the U.S. Coast Guard do not have their own respective ROTC programs; rather, graduates of Naval ROTC programs have the option to serve as officers in the Marine Corps contingent on meeting Marine Corps requirements. In 2020, ROTC graduates constituted 70 percent of newly commissioned active-duty U.S. Army officers, 83 percent of newly commissioned U.S. Marine Corps officers (through NROTC), 61 percent of newly commissioned U.S. Navy officers and 63 percent of newly commissioned U.S. Air Force officers, for a combined 56 percent of all active-duty officers in the Department of Defense commissioned that year. Under ROTC, a student may receive a competitive, mer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States West Coast
The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but sometimes includes Alaska and Hawaii, especially by the United States Census Bureau as a U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia Britannica'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although the enc ...

Army Signal Corps
The United States Army Signal Corps (USASC) is a branch of the United States Army that creates and manages communications and information systems for the command and control of combined arms forces. It was established in 1860, the brainchild of Major Albert J. Myer, and had an important role in the American Civil War.

USCGC Acacia (WAGL-200)
USCGC ''Acacia'' (WAGL-200) was originally built for service by the U.S. Army as a mine planter shortly after World War I and later transferred to the U.S. Lighthouse Service, which became part of the U.S. Coast Guard in 1939; when transferred the ship was redesignated as a ''Speedwell''-class buoy tender. She was sunk in 1942 by a German U-boat. Construction ''Acacia'' was laid down by Fabricated Shipbuilding Corporation and Coddington Engineering Company, Milwaukee, Wisconsin, as the mine planter USAMP ''General John P. Story'', for the U.S. Army, sometime around 1 October 1918. She was named for Major General John Patten Story, Chief of Artillery 1904–1905. She was launched on 15 September 1919 and was delivered around 1 May 1920, then commissioned into the Army's Mine Planter Service at Milwaukee.

Lighthouse Tender
A lighthouse tender is a ship specifically designed to maintain, support, or tend to lighthouses or lightvessels, providing supplies, fuel, mail, and transportation. In the United States, these ships originally served as part of the Lighthouse Service and now are part of the Coast Guard.

Harbor Defense Command
A Harbor Defense Command was a military organization of the United States Army Coast Artillery Corps designated in 1925 from predecessor organizations dating from circa 1895. It consisted of the forts, controlled underwater minefields, and other coastal defenses of a particular harbor or river. Harbor Defense Commands, along with the similar Coast Artillery Corps, were disestablished in 1950. History These commands originated as Artillery Districts, to control groups of forts constructed under the Endicott Program beginning in 1895. A 1909 reference shows that districts could include (depending on size) a Battle Command (later Fort Command), Fire Command, Mine Command, and Battery Commands. Mine planter vessels were also attached to these commands to plant and maintain controlled minefields. In 1913 the districts were redesignated as Coast Defense Commands, called "Coast Defenses of..." the area protected.Rinaldi, pp. 165-166 At this time Coast Artillery Districts became regional ...

Faliro
Phalerum or Phaleron ( ''()'', ; ''()'', ) was a port of Ancient Athens, 5 km southwest of the Acropolis of Athens, on a bay of the Saronic Gulf. The bay is also referred to as "Bay of Phalerum" ( el, Όρμος Φαλήρου '').'' The area of Phalerum is now occupied by the towns Palaio Faliro, Kallithea, Moschato and Neo Faliro, all of which are part of the Athens agglomeration. Phalerum was the major port of Athens before Themistocles had the three rocky natural harbours by the promontory of Piraeus developed as alternative, from 491 BC. It was said that Menestheus set sail with his fleet to Troy from Phalerum, as so did Theseus when he sailed to Crete after the death of Androgeus. Recently, archaeologists have uncovered what appear to be traces of ancient Athens’s first port before the city’s naval and shipping centre was moved to Piraeus. The site, some 350 m from the modern coastline, contained pottery, tracks from the carts that would have served the port, an ...

Cable Ship
A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves for guiding cable over bow or stern or both. Bow sheaves, some very large, were characteristic of all cable ships in the past, but newer ships are tending toward having stern sheaves only, as seen in the photo of CS ''Cable Innovator'' at the Port of Astoria on this page. The names of cable ships are often preceded by "C.S." as in CS ''Long Lines''. The first transatlantic telegraph cable was laid by cable layers in 1857–58. It briefly enabled telecommunication between Europe and North America before misuse resulted in failure of the line. In 1866 the successfully laid two transatlantic cables, securing future communication between the continents. Modern cable ships Cable ships have unique requirements related to having long idle periods in port be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
