Onversaagd-class Minesweeper
The ''Onversaagd'' class was a ship class of six minesweepers that were built in the United States for the Royal Netherlands Navy (RNN). They were paid for by the United States under the Mutual Defense Assistance Program (MDAP). The minesweepers were based on the design of the and taken into service of the RNN between 1954 and 1955.Roetering (1997), p. 131. Design To sweep naval mines the minesweepers of the ''Onversaagd'' class were equipped with the Wire Mk1, M Mk 6 A, A Mk 6B and the A Mk 4v. Furthermore, the ships had a single 40 mm gun. In addition, the minesweepers were equipped with a prototype of the UQS-1, but this mine avoidance sonar did not meet expectations. While the ''Onversaagd''-class minesweepers had a range of , it was deemed insufficient, as it meant that the ships could only stay at sea for a maximum of eight to nine days without having to replenish its oil.Schoonoord (2012), p. 74.

Royal Netherlands Navy
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. Secondary na ...

Submarine Tender
A submarine tender is a type of depot ship that supplies and supports submarines. Development Submarines are small compared to most oceangoing vessels, and generally do not have the ability to carry large amounts of food, fuel, torpedoes, and other supplies, nor to carry a full array of maintenance equipment and personnel. The tender carries all these, and either meets submarines at sea to replenish them or provides these services while docked at a port near the area where the submarines are operating. In some navies, the tenders were equipped with workshops for maintenance, and as floating dormitories with relief crews. With the increased size and automation of modern submarines, plus in some navies the introduction of nuclear power, tenders are no longer as necessary for fuel as they once were. Canada Canada's first Submarine Depot Ship was . Chile The term used in the Chilean Navy is "submarine mother ship", as for example the BMS (buque madre de submarinos) ''Almirante M ...

Mine Countermeasures Vessel
A mine countermeasures vessel or MCMV is a type of naval ship designed for the location of and destruction of naval mines which combines the role of a minesweeper and minehunter A minehunter is a naval vessel that seeks, detects, and destroys individual naval mines. Minesweepers, on the other hand, clear mined areas as a whole, without prior detection of mines. A vessel that combines both of these roles is known as a ... in one hull. The term MCMV is also applied collectively to minehunters and minesweepers. References {{navy-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrographic Survey Vessel
A research vessel (RV or R/V) is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters. History The research ship had origins in the early voyages of exploration. By the time of James Cook's ''Endeavour'', the essentials of what today we would call a research ship are clearly apparent. In 1766, the Royal Society hired Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. The ''Endeavour'' was a sturdy vessel, well designed and equipped for the ordeals she would face, and fitted out with facilities for her "research personnel", Joseph Banks. As is common with contemporary research vessels, ''Endeavour'' also carried out more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vlissingen
Vlissingen (; zea, label=Zeelandic, Vlissienge), historically known in English as Flushing, is a Municipalities of the Netherlands, municipality and a city in the southwestern Netherlands on the former island of Walcheren. With its strategic location between the Scheldt river and the North Sea, Vlissingen has been an important harbour for centuries. It was granted City rights in the Netherlands, city rights in 1315. In the 17th century Vlissingen was a main harbour for ships of the Dutch East India Company (VOC). It is also known as the birthplace of Admiral Michiel de Ruyter. Vlissingen is mainly noted for the yards on the Scheldt where most of the ships of the Royal Netherlands Navy (''Koninklijke Marine'') are built. Geography The municipality of Vlissingen consists of the following places: * City: Vlissingen * Villages: Oost-Souburg, Ritthem, and West-Souburg * Hamlet: Groot-Abeele History The fishermen's hamlet that came into existence at the estuary of the Schelde a ...

Museum Ship
A museum ship, also called a memorial ship, is a ship that has been preserved and converted into a museum open to the public for educational or memorial purposes. Some are also used for training and recruitment purposes, mostly for the small number of museum ships that are still operational and thus capable of regular movement. Several hundred museum ships are kept around the world, with around 175 of them organised in the Historic Naval Ships AssociationAbout The Historic Naval Ships Association (the international website.

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 ...

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Mutual Defense Assistance Act
The Mutual Defense Assistance Act was a United States Act of Congress signed by President Harry S. Truman on 6 October 1949. For US Foreign policy, it was the first U.S. military foreign aid legislation of the Cold War era, and initially to Europe. The Act followed Truman's signing of the Economic Cooperation Act (the Marshall Plan), on April 3, 1948, which provided non-military, economic reconstruction and development aid to Europe. The 1949 Act was amended and reauthorized on July 26, 1950. In 1951, the Economic Cooperation Act and Mutual Defense Assistance Act were succeeded by the Mutual Security Act, and its newly created independent agency, the Mutual Security Administration, to supervise all foreign aid programs, including both military assistance programs and non-military, economic assistance programs that bolstered the defense capability of U.S. allies. About the same time, the Mutual Defense Assistance Control Act of 1951, also known or referred to as the Battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trouw
''Trouw'' (; ) is a Dutch daily newspaper appearing in compact size. It was founded in 1943 as an orthodox Protestant underground newspaper during World War II. Since 2009, it has been owned by DPG Media (known as De Persgroep until 2019). ''Trouw'' received the European Newspaper Award in 2012. Cees van der Laan is the current editor-in-chief. History ''Trouw'' is a Dutch word meaning "fidelity", "loyalty", or "allegiance", and is cognate with the English adjective "true". The name was chosen to reflect allegiance and loyalty to God and Country in spite of the German occupation of the Netherlands. ''Trouw'' was started during World War II by members of the Dutch Protestant resistance. Hundreds of people involved in the production and distribution of the newspaper were arrested and killed during the war. The newspaper was published irregularly during the war due to lack of paper. In 1944 the Nazi occupying forces tried to stop publication by rounding up and imprisoning some 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minesweeper
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing Grappling hook, grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their ...
