Submarine Command Course
The Submarine Command Course (SMCC), previously known as the Commanding Officers Qualifying Course (COQC), is a training course for naval officers preparing to take command of a submarine. It is informally known as The Perisher. Created by the Royal Navy during World War I, the course was originally intended to address the high attrition rate of submarine commanders, as the previous method of handing down knowledge from officer to officer was prevented by wartime deaths. Following World War II, the Royal Netherlands Navy became involved in the course; the Dutch later partnered with the British to run the course, and following the British conversion to a fully nuclear submarine fleet, took over responsibility for running the course for diesel-electric submarines. Officers from other nations regularly participate. The four-month course is run in four stages, the first and third involve learning ashore in simulators, while the second involves learning at sea. The fourth phase is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vanguard At Faslane 03
The vanguard (sometimes abbreviated to van and also called the advance guard) is the leading part of an advancing military formation. It has a number of functions, including seeking out the enemy and securing ground in advance of the main force. In naval warfare the van is the advance ship, or fleet, that will make the initial engagement with an enemy Naval fleet, fleet. History The vanguard derives from the traditional division of a medieval army into three Battle (formation), battles or ''wards''; the Van, the Main (or Middle), and the Rearguard, Rear. The term originated from the medieval French ''avant-garde'', i.e. "the advance guard". The vanguard would lead the line of march and would deploy first on the field of battle, either in front of the other wards or to the right if they deployed in Line (formation), line. The makeup of the vanguard of a 15th century Duchy of Burgundy, Burgundian army is a typical example. This consisted of: *A contingent of Light cavalry, forer ...

International Organization For Standardization
The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and () it has published over 25,000 international standards covering almost all aspects of technology and manufacturing. It has over 800 technical committees (TCs) and subcommittees (SCs) to take care of standards development. The organization develops and publishes international standards in technical and nontechnical fields, including everything from manufactured products and technology to food safety, transport, IT, agriculture, and healthcare. More specialized topics like electrical and electronic engineering are instead handled by the International Electrotechnical Commission.Editors of Encyclopedia Britannica. 3 June 2021.Inte ...

Naval Education And Training In The United Kingdom
A navy, naval force, military maritime fleet, war navy, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect 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-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications ( brown-wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Navy Submarine Service
The Royal Navy Submarine Service is one of the five fighting arms of the Royal Navy. It is sometimes known as the Silent Service, as submarines are generally required to operate undetected. The service operates six fleet submarines ( SSNs), of the and es (with two further ''Astute''-class boats currently under construction), and four ballistic missile submarines (SSBN), of the . All of these submarines are nuclear powered. The Royal Navy's senior submariner was for many years located at in Hampshire. It moved from ''Dolphin'' to the Northwood Headquarters in 1978. The Submarine School is now at at Torpoint in Cornwall. History In 1900 the Royal Navy ordered five submarines from Vickers Shipbuilding and Engineering of Barrow-in-Furness, designed by Electric Boat Company. The following year the first submarine, , was launched, and the navy recruited six officers for the Submarine Service, under Reginald Bacon as Inspecting Captain of Submarines. At the beginning of World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Submarine Warfare Insignia
The Submarine Warfare Insignia (usually known as '"Dolphins"') are worn by qualified submariners. United States Navy Officers and Enlisted Sailors wear a Military badges of the United States, uniform breast pin to indicate that they are qualified in submarines. The ''Submarine Warfare Insignia'' is considered one of the Navy's three major enlisted warfare pins, along with the Surface Warfare Badge and the Enlisted Aviation Warfare Specialist insignia. To earn the right to wear "dolphins", prospective submariners complete an extensive qualification process that lasts about one year (for both enlisted and officers, though the two programs differ significantly) and covers all of the submarine's systems. History On 13 June 1923, Captain Ernest J. King, Commander, Submarine Division Three (later Fleet admiral (United States), Fleet Admiral and Chief of Naval Operations during World War II), suggested to the Secretary of the Navy (Bureau of Navigation) that a distinguishing de ...

Situational Awareness
Situational awareness or situation awareness, often abbreviated as SA is the understanding of an environment, its elements, and how it changes with respect to time or other factors. It is also defined as the perception of the elements in the environment considering time and space, the understanding of their meaning, and the prediction of their status in the near future. It is also defined as adaptive, externally-directed consciousness focused on acquiring knowledge about a dynamic task environment and directed action within that environment. Situation awareness is recognized as a critical foundation for successful decision making in many situations, including the ones which involve the protection of human life and property, such as law enforcement, aviation, air traffic control, ship navigation,Nullmeyer, R.T., Stella, D., Montijo, G.A., & Harden, S.W.

Active 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 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) to extrem ...

Fin (submarine)
In naval parlance, the sail (American usage) or fin (British/Commonwealth usage) (also known as a fairwater) of a submarine is the tower-like structure found on the dorsal (topside) surface of submarines. Submarine sails once housed the conning tower (command and communications data center), and continue to house the periscope(s), radar and communications masts ( antenna). When above the water's surface, the sail serves as an observation platform. It also provides an entrance and exit point on the submarine that has enough freeboard to prevent the submarine being swamped. Under water, the sail acts as a vertical stabilizer. In some submarines, the sail also supports diving planes (or fairwater planes), which are control surfaces used for depth control while underwater.Office of Naval ResearchSubmarines - How They Work.

Military Exercise
A military exercise, training exercise, maneuver (manoeuvre), or war game is the employment of military resources in Military education and training, training for military operations. Military exercises are conducted to explore the effects of warfare or test tactics and strategies without actual combat. They also ensure the combat readiness of garrisoned or deployable forces prior to deployment from a home base. While both war games and military exercises aim to simulate real conditions and scenarios for the purpose of preparing and analyzing those scenarios, the distinction between a war game and a military exercise is determined, primarily, by the involvement of actual military forces within the simulation, or lack thereof. Military exercises focus on the simulation of real, full-scale military operations in controlled hostile conditions in attempts to reproduce war time decisions and activities for training purposes or to analyze the outcome of possible war time decisions.

Corruption (linguistics)
Language change is the process of alteration in the features of a single language, or of languages in general, over time. It is studied in several subfields of linguistics: historical linguistics, sociolinguistics, and evolutionary linguistics. Traditional theories of historical linguistics identify three main types of change: systematic change in the pronunciation of phonemes, or sound change; borrowing, in which features of a language or dialect are introduced or altered as a result of influence from another language or dialect; and analogical change, in which the shape or grammatical behavior of a word is altered to more closely resemble that of another word. Research on language change generally assumes the uniformitarian principle—the presumption that language changes in the past took place according to the same general principles as language changes visible in the present. Language change usually does not occur suddenly, but rather takes place via an extended period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Den Helder
Den Helder () is a municipality and a city in the Netherlands, in the province of North Holland. Den Helder occupies the northernmost point of the North Holland peninsula. It is home to the country's main naval base. From here the Royal TESO ferryboat service operates the transportation link between Den Helder and the nearby Dutch Wadden island of Texel to the north. Etymology Before the year 1928, the official name of Den Helder was Helder. The origin of the name Helder is not entirely clear. The name Helder may have come from ''Helle/Helde'', which means "hill" or "hilly grounds", or from ''Helre'', which means a sandy ridge. Another explanation is that the name derived from ''Helsdeur'' (Hell's Door), likely because in the water between Den Helder and Texel (called Marsdiep) the current was so strong that many ships were lost. History Huisduinen was the original older part of the city, whereas Helder itself was a nearby smaller hamlet. When a harbour was built near Hel ...
