HSwMS Gotland (Gtd)
HSwMS ''Gotland'' (Gtd) is a defense submarine of the Swedish Navy. It was the first ship of the , which was the first operational submarine class in the world to use air-independent propulsion in the form of Stirling engines which use liquid oxygen and diesel as the propellant. It was built by Kockums, launched in 1995, and subsequently commissioned in 1996. In 2015, Sweden's Defense Material Administration (FMV) signed a contract with Saab Kockums which included a mid-life upgrade of two members of the ''Gotland'' class, ''Gotland'' and ''Halland'', for SEK 2.1 billion. ''Gotland'' is expected to return to the FMV in late 2018 following a series of platform and combat systems upgrades. Construction The submarine ''Gotland'' was designed and built by Kockums in Malmö and launched on 2 February 1995. The honor guard during the launching consisted of the amphibian company of the Fårösund Marine Brigade (FMB). Participants from Gotland included the governor, the municipal co ...

Gotland
Gotland (, ; ''Gutland'' in Gutnish), also historically spelled Gottland or Gothland (), is Sweden's largest island. It is also a province, county, municipality, and diocese. The province includes the islands of Fårö and Gotska Sandön to the north, as well as the Karlsö Islands ( Lilla and Stora) to the west. The population is 61,001, of which about 23,600 live in Visby, the main town. Outside Visby, there are minor settlements and a mainly rural population. The island of Gotland and the other areas of the province of Gotland make up less than one percent of Sweden's total land area. The county formed by the archipelago is the second smallest by area and is the least populated in Sweden. In spite of the small size due to its narrow width, the driving distance between the furthermost points of the populated islands is about . Gotland is a fully integrated part of Sweden with no particular autonomy, unlike several other offshore island groups in Europe. Historically there was ...

Gotland Coastal Artillery Regiment
The Gotland Coastal Artillery Regiment ( sv, Gotlands kustartilleriregemente), designation KA 3, was a Swedish Navy coastal artillery regiment of the Swedish Armed Forces which operated between 1937 and 2000. The unit was based in Fårösund in Gotland. History The military presence in the areas around northern Gotland began in connection with the Crimean War. Fårösund became a strategically important place. English and French fleets used the sound as a base, stage station and observation point during the war against Russia. In 1885 there was a new concern between Russia and England. New ships were expected. Both Russia and Germany demanded that Fårösund be fortified if the Swedish neutrality was to be recognized and respected. It was the start of the Swedish Coastal Artillery, which was established in the early 1900s. The Swedish Armed Forces bought land and buildings and hired people. In 1885 work began on fortifications in Slite and Fårösund where artillerymen from Gotland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heavy-lift Ship
A heavy-lift ship is a vessel designed to move very large loads that cannot be handled by normal ships. They are of two types: *''Semi-submersible'' ships that take on water ballast to allow the load—usually another vessel—to be floated over the deck, whereupon the ballast is jettisoned and the ship's deck and cargo raised above the waterline. *''Project cargo'' ships that use at least one heavy-lift crane for handling heavy cargo and sufficient ballast to assure stability and sea-keeping properties. Description There are several types of heavy-lift ships: Semi-submersible ships Semi-submersible heavy-lift ships have a long and low well deck between a forward pilot house and an aft machinery space. In superficial appearance, it is somewhat similar to a dry bulk carrier or some forms of oil tanker. Its ballast tanks can be flooded to lower the well deck below the water's surface, allowing oil platforms, other vessels, or other floating cargo to be moved into position f ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blekinge-class Submarine
The ''Blekinge''-class submarine is the next generation of submarines developed by Kockums for the Swedish Navy, also known as the A26 type. First planned at the beginning of the 1990s, the project was called "''U-båt 2000''" and was intended to be ready by the late 1990s or early 2000. With the end of the Cold War the naval threat from the Soviet Union disappeared and the new submarine class was deemed unnecessary. The project lay dormant for years until the mid-2000s when the need for a replacement for the became apparent. Originally the Scandinavian countries had intended to collaborate on the , but Denmark's withdrawal from submarine operations meant that Kockums proceeded on their own. In February 2014 the project was cancelled because of disagreements between Kockums's new German owners, ThyssenKrupp, and the Swedish government. ThyssenKrupp refused to send a complete offer to any potential buyer, and demanded that each one buyer pay for the entire development rather tha ...

HSwMS Uppland (Upd)
HSwMS ''Uppland'' (Upd) is one of three built for the Royal Swedish Navy during the Cold War.Saunders, p. 698 The motto of HSwMS ''Uppland'' is "Prudencia Et Audacia" which translates into "Prudence And Boldness". Mid-life upgrade In 2020, HSwMS ''Uppland'' underwent a mid-life update. During the upgrade, a number of systems that will be used in the next generation submarines, the ''Blekinge''-class (A26), were installed. More than 20 new systems on board the new ''Gotland''-class was implemented, which contributes to their de-risking for the A26. This also offers training opportunities for the crew when they deploy the A26 in the future. The upgrade process included many new systems, such as the Stirling AIP, a completely new mast suite, sonars and sensors as well as management and communication systems. In order to accommodate all systems, the submarine has extended to 62 m and gained another 200 tons in weight. In the process HSwMS ''Uppland'' reached a displacement ...

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 ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Västergötland-class Submarine
The ''Västergötland'' class of diesel-electric submarines entered service in 1987 in the Swedish Navy allowing the last Draken_II-class_submarine, Draken II class of subs to be retired. History The original four ships of the class (''Västergötland'', ''Hälsingland'', ''Södermanland'', and ''Östergötland'') were built between 1983 and 1988 by Kockums AB. The latter two have undergone comprehensive refits, including the insertion of a new hull section with an air-independent propulsion system equipped with Stirling engines. They have been recommissioned in 2003–2004 as the new . ''Västergötland'' and ''Hälsingland'' were put in reserve until November 2005, when they were sold to the Republic of Singapore Navy as the . They were refitted to ''Södermanland'' class standards and received additional climatisation for use in tropical waters, and relaunched in 2009–2010. ''Östergötland'' was decommissioned in 2021, leaving ''Södermanland'' as the last remaining ship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
