Spica-class Torpedo Boat (Sweden)
The ''Spica'' class was a class of six fast torpedo boats built for the Swedish Navy in the 1960s and decommissioned in the late 1980s. One ship, , is preserved as a museum ship in Stockholm, Sweden. History The ships were ordered in 1961 as part of a re-armament programme for defending Sweden's coastline. Tenders were sought from various European boat builders in the United Kingdom, Norway and Germany including Lurssen who offered the new ''Jaguar''-class design. The Swedes ended up designing a bespoke vessel which became the template for subsequent Swedish fast attack craft. Design The hull was made of steel, unlike some other contemporary designs which used plywood. Although the boat had a relatively small hull and displacement, this provided a stable platform. The Bridge and Operations Room were located at the rolling and stamping centre of the ship which further improved stability for the crew especially in high seas. The boats were fitted with an CBRN, NBC support syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fire Control Radar
A fire-control radar (FCR) is a radar that is designed specifically to provide information (mainly target azimuth, elevation angle, elevation, ranging, range and range rate) to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar. A typical fire-control radar emits a Pencil (optics), narrow, intense beam of radio waves to ensure accurate tracking information and to minimize the chance of losing track of the target. This makes them less suitable for initial detection of the target, and FCRs are often partnered with a medium-range search radar to fill this role. In British terminology, these medium-range systems were known as tactical control radars. Most modern radars have a track-while-scan capability, enabling them to function simultaneously as both fire-control radar and se ...

Torpedo Boat Classes
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though some ...

United States Naval Institute
The United States Naval Institute (USNI) is a private non-profit military association that offers independent, nonpartisan forums for debate of national security issues. In addition to publishing magazines and books, the Naval Institute holds several annual conferences. The Naval Institute is based in Annapolis, Maryland. Established in 1873, the Naval Institute claimed "almost 50,000 members" in 2020, mostly active and retired personnel of the United States Navy, Marine Corps, and Coast Guard. The organization also has members in over 90 countries. The organization has no official or funding ties to the United States Naval Academy or the U.S. Navy, though it is based on the grounds of the Naval Academy through permission granted by a 1936 Act of Congress. History The U.S. Naval Institute was formed on October 9, 1873 by fifteen naval officers gathered at the U.S. Naval Academy's Department of Physics and Chemistry building in Annapolis to discuss, among other topics, the impli ...

Karlskrona
Karlskrona (, , ) is a locality and the seat of Karlskrona Municipality, Blekinge County, Sweden with a population of 66,675 in 2018. It is also the capital of Blekinge County. Karlskrona is known as Sweden's only baroque city and is host to Sweden's largest naval base and the headquarters of the Swedish Coast Guard. Historically, the city has been home to a German minority, thus enabling the formation of a German Congregational church. It also counted Jewish people in its population. In 1998, parts of the city, including the Karlskrona naval base, was declared a UNESCO World Heritage Site. History The island on which Karlskrona was built, Trossö, was owned during the 17th century by the farmer Vittus Andersson. Under Danish rule, there was another, older town called Lyckå on the mainland a couple of kilometers away. A little further away, the Danes had started to build Kristianopel before Blekinge fell under Swedish rule in 1658. Until 1679, the island and the nearby isl ...

Vasa Museum
The Vasa Museum ( sv, Vasamuseet) is a maritime museum in Stockholm, Sweden. Located on the island of Djurgården, the museum displays the only almost fully intact 17th-century ship that has ever been salvaged, the 64-gun warship '' Vasa'' that sank on her maiden voyage in 1628. The Vasa Museum opened in 1990 and, according to the official website, is the most visited museum in Scandinavia. Together with other museums such as the Stockholm Maritime Museum, it belongs to the Swedish National Maritime Museums (SNMM). History From the beginning of 1961 to 1983, ''Vasa'' was housed in a temporary structure called Wasavarvet ("The Vasa Shipyard") where she was treated with polyethylene glycol. Visitors could only view the ship from two levels and the maximum distance was only 5 m (17 ft). In 1981, the Swedish government decided that a permanent ''Vasa'' museum was to be constructed and a competition for the design of the museum building was organized. A total of 384 archite ...

Missile Boat
A missile boat or missile cutter is a small, fast warship armed with anti-ship missiles. Being smaller than other warships such as destroyers and frigates, missile boats are popular with nations interested in forming a navy at lower cost. They are similar in concept to the torpedo boats of World War II; in fact, the first missile boats were modified torpedo boats with the torpedo tubes replaced by missile tubes. The doctrine behind the use of missile boats is based on the principle of mobility over defence and firepower. The advent of proper guided missile and electronic countermeasure technologies gave birth to the idea that warships could now be designed to outmaneuver their enemies and conceal themselves while carrying powerful weapons. Previously, increasing the potency of naval artillery required larger projectiles, which required larger and heavier guns, which in turn called for larger ships to carry these guns and their ammunition and absorb their recoil. This trend culm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HSwMS Virgo (T126)
HSwMS ''Virgo'' (T126) was a Swedish Navy ''Spica''-class, torpedo-armed, fast attack craft (FAC). Design The hull was made of steel, unlike some other contemporary designs which used plywood. Although the boat had a relatively small hull and displacement, this provided a stable platform. The Bridge and Operations Room were located at the rolling and stamping centre of the ship which further improved stability for the crew especially in high seas. The boats were fitted with an NBC support system where the hull could be closed down in the event of having to operate in a nuclear fall-out area. Construction and career The vessel was one of three constructed in the 1960s by Karlskronavarvet, the other two being HSwMS ''Castor'' (T124) and HSwMS ''Vega'' (T125). Three similar vessels were built by Götaverken AB at Hisingen. She was launched on 10 September 1966. The vessel was taken out of service on 1 November 1989.Gustaf von Hofsten, Jan Waernberg (2003).
