HSwMS Sjölejonet (Sle)
HSwMS ''Sjölejonet'' (Sle), ( Sw. meaning ''sea lion''), was the second ship of the Swedish submarine class ''Sjöormen'', project name A11. Development The planning of the class included a number of different AIP solutions including nuclear propulsion. However, the ships where finally completed with for the time extremely large batteries. The ship was a single-hulled submarine, with hull shape influenced by the American experimental submarine . The hull was covered with rubber tiles to reduce the acoustic signature (anechoic tiles), at this time a pioneer technology. The also pioneered the use of an x-shaped (as opposed to cross-shaped) rudder as a standard (as opposed to experimental) feature. Service in Sweden The submarine served in the Swedish Navy for almost 30 years and was then sold to Singapore in 1997 together with its four sister ships. Service in Singapore HSwMS ''Sjöbjörnen'' was renamed RSS ''Conqueror'' after Singapore acquired the boat on 28 May 19 ...

Karlskrona Naval Base
The Karlskrona naval base () is the largest naval base of the Swedish Navy. Located in Blekinge in southern Sweden, the base has close ties with the city of Karlskrona. It has an exceptionally well-sheltered location: arcs of islands provide a strong defense not only from the sea but also from land attacks. Two of Sweden's three naval warfare flotillas are based there. It contains the Marinmuseum and the Ropewalk, the longest wooden building in the country. History After Sweden and Denmark ceased hostilities after the Scanian War (1675–1679), King Charles XI of Sweden made a reconnaissance trip in the eastern part of the Blekinge archipelago. The king decreed the construction of a city named "Carlscroona" on the island of Trossön. The major reason for its establishment was to provide the Swedish Navy with a permanent base closer to Denmark, which throughout the 17th century had been the foremost enemy of Sweden. In addition, a shipyard was needed for both construction a ...

Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Ships Built In Malmö
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%). Nomenclature Ships are typically larger than boats, but there is no ...

Cooperation Afloat Readiness And Training
The Cooperation Afloat Readiness and Training (CARAT) is a series of annual bilateral military exercises conducted by the United States Pacific Fleet, with several member nations of ASEAN in Southeast Asia. Currently, the navies of Bangladesh, Brunei Darussalam, Cambodia, Indonesia, Malaysia, Philippines, Singapore, Sri Lanka, and Thailand participate. Objectives of CARAT include enhancing regional cooperation; building friendships, and strengthening professional skills. In 2010, Cambodia and Bangladesh became the first CARAT participants to join the exercise since 1995. CARAT 2011 The objective of CARAT 2011 was to enhance regional naval cooperation by strengthening the professional skills of its participants. Task Force 73 served as the U.S. Navy executive agent for the CARAT 2011 exercises.

Republic Of Singapore Navy
The Republic of Singapore Navy (RSN) is the Naval warfare, maritime Military branch, service branch of the Singapore Armed Forces (SAF) responsible for defending the country against any seaborne threats and as a guarantor of its sea lines of communications. The RSN traces its origins to the Royal Navy when Singapore was still a crown colony of the British Empire. The service was formally established in 1967, two years after its independence from Malaysia in 1965, and had undergone a substantial modernisation ever since – which has led them into becoming the most powerful navy in Southeast Asia. The RSN also regularly conducts operations with the navies of its neighbouring countries to combat Piracy in the Strait of Malacca, piracy and terrorist threats in the congested littoral waters of the Strait of Malacca and Singapore. It also jointly operates the Fokker 50 maritime patrol aircraft with its counterparts from the Republic of Singapore Air Force (RSAF) to provide air surv ...

Swedish Navy
The Swedish Navy () is the maritime service branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet (), formally sometimes referred to as the Royal Navy () – as well as marine units, the Amphibious Corps (). Founded under King Gustav Vasa in 1522, the Swedish navy is one of the oldest continuously serving navies in the world, celebrating its 500th anniversary in 2022. History Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a tax. In 1427, when Sweden was part of the Kalmar Union (with Denmark and Norway), Swedish warships did however participate in the naval battle of Öresund against the Hanseatic League. It is unclear how this force was ...

Anechoic Tile
__NOTOC__ Anechoic tiles are rubber or synthetic polymer tiles containing thousands of tiny voids, applied to the outer hulls of military ships and submarines, as well as anechoic chambers. Their function is twofold: *To absorb the sound waves of active sonar, reducing and distorting the return signal, thereby reducing its effective range. *To attenuate the sounds emitted from the vessel, typically its engines, to reduce the range at which it can be detected by passive sonar. Development in the Third Reich The technology of anechoic tiles was developed by the ''Kriegsmarine'' during the Second World War, codenamed ''Alberich'' after the invisible guardian dwarf of the Rhinegold treasure from Richard Wagner's Der Ring des Nibelungen music dramas. The coating consisted of sheets approximately square and thick, with rows of holes in two sizes, and in diameter. Manufactured by IG Farben as a specially formed synthetic rubber tile and made using a stabilized, non-polar, hig ...

Air-independent Propulsion
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels. Modern non-nuclear submarines are potentially stealthier than nuclear submarines; although some modern submarine reactors are designed to rely on natural circulation, most naval nuclear reactors use pumps to constantly circulate the reactor coolant, generating some amount of detectable noise. Non-nuclear submarines running on battery power or AIP, on the other hand, can be virtually silent. While nuclear-powered designs still dominate in submergence times, speed, range and deep-ocean performance, small, high-tech non-nuclear attack submarines can be highly effective in coastal operations and pose a significant threat to less-stealthy and less-maneuverable nuclear submarines. A ...
