HSwMS Springaren (1961)
HSwMS ''Springaren'' (Sp), was the sixth boat of the ''Draken''-class submarine of the Swedish Navy. Construction and career HSwMS ''Springaren'' was launched on 31 August 1961 by Saab Kockums, Malmö and commissioned on 7 November 1962. On September 24, 1980, ''Springaren'' was extremely close to colliding with an unknown submarine east of Huvudskär. During an exercise, she operated together with one of the Navy's anti-submarine helicopters. The hydrophone operator on ''Springaren'' reads a hydrophone effect. It sounds like a rattling moped at high speed. The connecting helicopters also detect the visitor, and immediately classify it as a submarine. The incident was followed by a two-week submarine hunt. She was decommissioned on 1 October 1987 and later scrapped in Muskö Muskö is an island in the southern part of Stockholm archipelago, which forms part of Haninge Municipality, Stockholm County, Sweden. It is best known for the Muskö naval base. There are also tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age was ...

Saab Kockums
Saab Kockums Aktiebolag, AB is a shipyard headquartered in Malmö, Sweden, owned by the Swedish defence company Saab Group. Saab Kockums AB is further operational in Muskö naval base, Muskö, Dockstavarvet, Docksta, and Karlskrona shipyard, Karlskrona. While having a history of civil vessel construction, Kockums' most renowned activity is the fabrication of military corvettes and submarines. Kockums worked with Northrop Grumman and Howaldtswerke-Deutsche Werft (HDW) to offer a Visby-class corvette, ''Visby''-class corvette derivative in the American Focused Mission Vessel Study, a precursor to the Littoral Combat Ship program. It competed with several other concepts, including Norway's Skjold class (part of a Raytheon led group). History Kockums during the 19th century During the 1820:s the Kockums family established themselves as Businessperson, businesspeople in Malmö. Frans Henrik Kockum built a large fortune through an investment in tobacco production. Thanks to this h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse
The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, ''Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators, and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draken-class Submarine
The ''Draken'' class (''Dragon'') was a submarine class built for the Swedish Navy from 1960 to 1962. A total of six submarines were delivered. Four of the boats were modernised in 1981–82. The design was a modified version of the with only one shaft with a larger 5-bladed propeller for improved underwater performance and reduced noise. Draken, Vargen, Nordkaparen and Springaren were ordered from Kockums. Gripen and Delfinen were from Karlskrona. These boats were decommissioned 1988-90 and were succeeded by the Sjöormen-class and Näcken-class submarines. The names of the six Draken class are Draken, Gripen, Vargen, Delfinen, Nordkaparen and Springaren. One submarine () was preserved and can today been seen at the Maritiman in Gothenburg Gothenburg (; abbreviated Gbg; sv, Göteborg ) is the second-largest city in Sweden, fifth-largest in the Nordic countries, and capital of the Västra Götaland County.

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

Swedish Navy
The Swedish Navy ( sv, Svenska marinen) is the naval branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet () – as well as marine units, the Amphibious Corps (). In Swedish, vessels of the Swedish Navy are given the prefix "HMS", short for (His/Her Majesty's Ship). In English, this is sometimes changed to "HSwMS" ("His Swedish Majesty's Ship") to differentiate Swedish vessels from those of the British Royal Navy. Founded under King Gustav I 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 ...

Launched (ship)
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Malmö
Malmö (, ; da, Malmø ) is the largest city in the Swedish county (län) of Scania (Skåne). It is the third-largest city in Sweden, after Stockholm and Gothenburg, and the sixth-largest city in the Nordic region, with a municipal population of 350,647 in 2021. The Malmö Metropolitan Region is home to over 700,000 people, and the Øresund Region, which includes Malmö and Copenhagen, is home to 4 million people. Malmö was one of the earliest and most industrialised towns in Scandinavia, but it struggled to adapt to post-industrialism. Since the 2000 completion of the Öresund Bridge, Malmö has undergone a major transformation, producing new architectural developments, supporting new biotech and IT companies, and attracting students through Malmö University and other higher education facilities. Over time, Malmö's demographics have changed and by the turn of the 2020s almost half the municipal population had a foreign background. The city contains many histori ...

Commissioned (ship)
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing correct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huvudskär
Huvudskär is a Swedish archipelago, consisting of about 200 rocks and islands, and a lighthouse. It is located in the Baltic Sea, in the southern part of the Stockholm archipelago. For many hundred years this area was very important for fishermen. Huvudskär is a very popular destination for sea travellers and tourists. The lighthouse In 1882 the first lighthouse was lit. This was placed on top of a keepers house made of wood. The lantern came from the deactivated lighthouse on Korsö. The light was a kerosene lamp. In 1931, the now standing tower was built and both the lantern and keepers house were removed. The new tower first ran on acetylene gas, and later was electrified. In 1992, solar power was installed to the lighthouse. It is owned and remote-controlled by the Swedish Maritime Administration.

Hydrophone
A hydrophone ( grc, ὕδωρ + φωνή, , water + sound) is a microphone designed to be used underwater for recording or listening to underwater sound. Most hydrophones are based on a piezoelectric transducer that generates an electric potential when subjected to a pressure change, such as a sound wave. Some piezoelectric transducers can also serve as a sound projector, but not all have this capability, and some may be destroyed if used in such a manner. A hydrophone can detect airborne sounds, but will be insensitive because it is designed to match the acoustic impedance of water, a denser fluid than air. Sound travels 4.3 times faster in water than in air, and a sound wave in water exerts a pressure 60 times that exerted by a wave of the same amplitude in air. Similarly, a standard microphone can be buried in the ground, or immersed in water if it is put in a waterproof container, but will give poor performance due to the similarly bad acoustic impedance match.
