ICGV Týr
ICGV ''Týr'' is an and the former flagship of the Icelandic Coast Guard. The ship was built by Dannebrog Værft in Denmark in 1974–1975 and entered service in 1975. ''Týr'' is the second largest ship in the Icelandic Coast Guard and participated in the Third Cod War. The ship conducted patrols, search and rescue, fishery inspections, general law enforcement and counter-terrorism operations in the Icelandic exclusive economic zone and the waters of the surrounding territories, such as Greenland and Jan Mayen. ''Týr'' was decommissioned in 2021 and sold in 2022. Description ''Týr'' has a standard displacement of and at full load. The ship measures long with a beam of and a draught of . The vessel is powered by two MAN 8L 40/54 diesel engines turning two shafts with Kamewa controllable pitch propellers rated at . This gives the ship a maximum speed of with a range of at . The vessels have a 20-ton bollard-pulling winch and passive rolling tanks. The ''Ægir'' cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Týr
(; Old Norse: , ) is a god in Germanic mythology, a valorous and powerful member of the and patron of warriors and mythological heroes. In Norse mythology, which provides most of the surviving narratives about gods among the Germanic peoples, sacrifices his hand to the monstrous wolf , who bites it off when he realizes the gods have bound him. is foretold of being consumed by the similarly monstrous dog during the events of Ragnarök. The generally renders the god as ''Mars'', the ancient Roman war god, and it is through that lens that most Latin references to the god occur. For example, the god may be referenced as (Latin 'Mars of the Assembly thing_(assembly).html" "title="nowiki/>thing (assembly)">Thing]') on 3rd century Latin inscription, reflecting a strong association with the Germanic thing (assembly), thing, a legislative body among the ancient Germanic peoples. By way of the opposite process of , Tuesday is named after (''s day'), rather than Mars, in English ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

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 ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Sperry Marine Northrop Grumman
Northrop Grumman Sperry Marine is a part of Northrop Grumman Mission Systems. Through various mergers, Northrop Grumman Sperry Marine was built out of companies including Decca Radars, Sperry Marine, and C. Plath and Litton Industries Litton Industries was a large defense contractor in the United States named after inventor Charles Litton Sr. During the 1960s, the company began acquiring many unrelated firms and became one of the largest conglomerates in the United States. .... The company is headquartered in New Malden, UK, with offices in Germany, Netherlands, Denmark, China, India, Singapore, South Korea, USA, and Canada. Sperry Marine is one of the oldest manufacturers of gyrocompasses. Its founder, Elmer Ambrose Sperry, was working on the first prototype of the gyrocompass at the same time as Hermann Anschütz-Kaempfe was developing his. Eventually, the rivalry between these two inventors over the gyrocompass went to court, where Albert Einstein was included as an ...
