Albacora-class Submarine
The ''Albacora'' class was a diesel-electric attack submarine (SSK) developed for the Portuguese Navy based on the French . In 1964, the Portuguese government ordered the construction of four of this class at the Dubigeòn-Normándie Shipyard to create the 4th Submarine Flotilla. With the first submarine commissioned on 1 October 1967, the Portuguese Navy started to have a submarine able to operate in both coastal and oceanic zones, especially in the Portuguese exclusive economic zone An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine natural resource, reso ....

British S-class Submarine (1931)
The S-class submarines of the Royal Navy were originally designed and built during the modernisation of the submarine force in the early 1930s to meet the need for smaller boats to patrol the restricted waters of the North Sea and the Mediterranean Sea, replacing the British H-class submarines. As part of the major naval construction for the Royal Navy during the Second World War, the S class became the single largest group of submarines ever built for the Royal Navy. A total of 62 were constructed over a period of 15 years, with fifty of the "improved" S class being launched between 1940 and 1945. At the start of the Second World War the S class was together with the British British U-class submarine, U and British T-class submarine, T class, Dutch and German Type VII submarine, Type VII one of the most advanced submarine classes in service at the time. Service The submarines operated in the waters around the United Kingdom and in the Mediterranean, and later in the Far East ...

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 ...

SEMT Pielstick
SEMT Pielstick was a French company that designed and built large diesel engines. Its full name was (Company of Thermal Machines Studies). Founded in 1948, SEMT was bought by MAN Diesel in 2006 During its existence as an independent company, SEMT manufactured engines for locomotives, naval vessels, Power station, power plants, and merchant ships. Its customers included France, the United States, Russia, India, and other countries. History SEMT. was created in 1946 by France's ministry for Industrial engineering, industrial production by combining five national companies: * (Saint-Nazaire), * (La Courneuve) * (Le Havre) * (Nantes) * (Denain) The aim of the new company was to develop new engines in France that could be licensed internationally. In 1948, the first licenses were supplied to licensed engine building companies worldwide. In 1951, after its relocation at La Courneuve, the was equipped with the first Testbed, test beds.

Portuguese Navy
The Portuguese Navy (), also known as the Portuguese War Navy (''Marinha de Guerra Portuguesa'') or as the Portuguese Armada (''Armada Portuguesa''), is the navy of the Portuguese Armed Forces. Chartered in 1317 by King Dinis of Portugal, it is List of navies, the oldest continuously serving navy in the world; in 2017, the Portuguese Navy commemorated the 700th anniversary of its official creation. The navy played a key role in Portuguese maritime exploration during the Age of Discovery in the 15th and 16th centuries. The result of this technical and scientific discoveries led Portugal to develop advanced ships, including the caravel, new and more sophisticated types of carracks for interoceanic travel and the oceanic galleon, Os Navios e as Técnicas Náuticas Atlânticas nos Séculos XV e XVI: Os Pilares da Estratégia 3C - Rear Admiral Antonio S ...

Exclusive Economic Zone
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine natural resource, resources, including energy production from water and wind. It stretches from the outer limit of the territorial sea (22.224 kilometres or 12 nautical miles from the baseline) out 370.4 kilometres (or 200 nautical miles) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the Territorial waters#Territorial sea, territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's righ ...

Type 209 Submarine
The Type 209 () is a range of diesel-electric attack submarines developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. Five class variants (Types 209/1100, 209/1200, 209/1300, 209/1400 and 209/1500), including modifications thereof, have been successfully exported to 15 countries, with 68 submarines being built and commissioned to five different variants between 1971 and 2021. More boats have been built to modified designs. The original variant, the Type 209/1100, was designed in the late 1960s with Greece becoming its first adopter. Turkey is the largest adopter, having purchased 14 submarines consisting of eight Type 209/1400 and six Type 209/1200 submarines. A non-specific variant was adopted by Israel as its first ''Dolphin'' class. The Type 209 family is the most widely proliferated submarine in Latin America, having been adopted by seven countries. Development In the early 1970s, many navies began to need replacements for World War II-era submari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 214 Submarine
The Type 214 is a class of diesel–electric powertrain, diesel–electric submarines developed exclusively for export by Howaldtswerke-Deutsche Werft, Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens AG, Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class combines the design principles of the Type 209 submarine family and the features of the Type 212A submarine. However, as an export design, it lacks some of the classified technologies of the Type 212 such as the non-magnetic steel hull that makes it difficult to detect using a magnetic anomaly detector. Due to improvements in the pressure hull materials, the Type 214 can dive nearly . It can also carry food, fresh water and fuel for 84 days of operation. A contract to build four submarines for the Hellenic Navy was signed 15 February 2000 and a fourth unit was ordered in June 2002. The first submarine was built at HDW in K ...

Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
