RFA Olwen (A122)
RFA ''Olwen'' (A122) was an ''Ol''-class "fast fleet tanker" of the Royal Fleet Auxiliary (RFA), the naval auxiliary fleet of the United Kingdom. She was the lead ship of her class, and launched in 1964 as RFA ''Olynthus'', the second ship to bear this name. She was renamed ''Olwen'' in 1967 to avoid confusion with the , HMS ''Olympus''. Operational history 1970 In November and December 1970 ''Olwen'' was involved in Operation Burlap giving humanitarian assistance to East Pakistan after a cyclone caused extensive damage and flooding. 1973 In the Second Cod War The Cod Wars ( is, Þorskastríðin; also known as , ; german: Kabeljaukriege) were a series of 20th-century confrontations between the United Kingdom (with aid from West Germany) and Iceland about fishing rights in the North Atlantic.

Royal Fleet Auxiliary
The Royal Fleet Auxiliary (RFA) is a naval auxiliary fleet owned by the UK's Ministry of Defence. It provides logistical and operational support to the Royal Navy and Royal Marines. The RFA ensures the Royal Navy is supplied and supported by providing fuel and stores through replenishment at sea, transporting Royal Marines and British Army personnel, providing medical care and transporting equipment and essentials around the world. In addition the RFA acts independently providing humanitarian aid, counter piracy and counter narcotic patrols together with assisting the Royal Navy in preventing conflict and securing international trade. They are a uniformed civilian branch of the Royal Navy staffed by British merchant sailors. RFA personnel are civilian employees of the Ministry of Defence and members of the Royal Naval Reserve and Sponsored Reserves. Although RFA personnel wear Merchant Navy rank insignia with naval uniforms, they are part of the Royal Navy. RFA vessels are ...

Cod Wars
The Cod Wars ( is, Þorskastríðin; also known as , ; german: Kabeljaukriege) were a series of 20th-century confrontations between the United Kingdom (with aid from West Germany) and Iceland about fishing rights in the North Atlantic. Each of the disputes ended with an Icelandic victory. Some Icelandic historians view the history of Iceland's struggle for control of its maritime resources in ten episodes, or ten cod wars. Fishing boats from Britain have been sailing to waters near Iceland in search of their catch since the 14th century. Agreements struck during the 15th century started a centuries-long series of intermittent disputes between the two countries. Demand for seafood and consequent competition for fish stocks grew rapidly in the 19th century. The modern disputes or wars began in 1952 after Iceland expanded its territorial waters from 3 to based on a decision by the International Court of Justice. The United Kingdom responded by banning Icelandic ships landing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

East Pakistan
East Pakistan was a Pakistani province established in 1955 by the One Unit Scheme, One Unit Policy, renaming the province as such from East Bengal, which, in modern times, is split between India and Bangladesh. Its land borders were with India and Myanmar, with a coastline on the Bay of Bengal. East Pakistanis were popularly known as "Pakistani Bengalis"; to distinguish this region from India's state West Bengal (which is also known as "Indian Bengal"), East Pakistan was known as "Pakistani Bengal". In 1971, East Pakistan became the newly independent state Bangladesh, which means "country of Bengal" in Bengali. East Pakistan was renamed from East Bengal by the One Unit Scheme of Pakistani Prime Minister Mohammad Ali of Bogra. The Constitution of Pakistan of 1956 replaced the Pakistani monarchy with an Islamic republic. Bengali politician H. S. Suhrawardy served as the Prime Minister of Pakistan between 1956 and 1957 and a Bengali bureaucrat Iskander Mirza became the first Presid ...

1970 Bhola Cyclone
The 1970 Bhola cyclone (Also known as the Great Cyclone of 1970) was a devastating tropical cyclone that struck East Pakistan (present-day Bangladesh) and India's West Bengal on November 11, 1970. It remains the deadliest tropical cyclone ever recorded and one of the world's deadliest natural disasters. At least 300,000 people lost their lives in the storm, possibly as many as 500,000, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. Bhola was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season. The cyclone formed over the central Bay of Bengal on November 8 and traveled northward, intensifying as it did so. It reached its peak with winds of on November 10, and made landfall on the coast of East Pakistan on the following afternoon. The storm surge devastated many of the offshore islands, wiping out villages and destroying crops throughout the region. In the most severely affected upazila, ...

HMS Olympus (S12)
HMS ''Olympus'' was an that served in the Royal Navy, and later in the Canadian Forces as a submarine trainer. Design and construction The ''Oberon'' class was a direct follow on of the ''Porpoise'' class, with the same dimensions and external design, but updates to equipment and internal fittings, and a higher grade of steel used for fabrication of the pressure hull.Cocker, p. 108 and constructed from a better grade of steel.Brown, p. 285Gardiner and Chumbley, p. 530 These build differences allowed the ''Oberon''s to have a deeper diving depth at roughly . As designed for British service, the ''Oberon''-class submarines were in length between perpendiculars and in length overall, with a beam of , and a draught of .Moore, p. 490 Displacement was standard, full load when surfaced, and full load when submerged. Propulsion machinery consisted of 2 Admiralty Standard Range 16 VMS diesel generators, and two electric motors, each driving a , 3-bladed propeller at up to 40 ...

Ship Class
A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, is a nuclear aircraft carrier (ship type) of the (ship class). In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. s' names all begin with T (, , ); and s are named after American battles (, , , ). Ships of the same class may be referred to as sister ships. Naval ship class naming conventions Overview The name of a naval ship class is most commonly the name of the lead ship, the first ship commissioned or built of its design. ...

Lead Ship
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ship ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Auxiliary Fleet
An auxiliary ship is a naval ship designed to support combatant ships and other naval operations. Auxiliary ships are not primary combatant vessels, though they may have some limited combat capacity, usually for purposes of self-defense. Auxiliary ships are extremely important for navies of all sizes because if they were not present the primary fleet vessels would be unsupported. Thus, virtually every navy maintains an extensive fleet of auxiliary ships. However, the composition and size of these auxiliary fleets vary depending on the nature of each navy and its primary mission. Smaller coastal navies tend to have smaller auxiliary vessels focusing primarily on littoral and training support roles. Larger blue-water navies tend to have larger auxiliary fleets comprising longer-range fleet support vessels designed to provide support far beyond territorial waters. Roles Replenishment One of the most direct ways that auxiliary ships support the fleet is by providing under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Replenishment Oiler
A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment (UNREP) at sea. Many countries have used replenishment oilers. The United States Navy's hull classification symbol for this type of ship was AOR. Replenishment oilers are slower and carry fewer dry stores than the U.S. Navy's modern fast combat support ships, which carry the classification AOE. History The development of the "oiler" paralleled the change from coal- to oil-fired boilers in warships. Prior to the adoption of oil fired machinery, navies could extend the range of their ships either by maintaining coaling stations or for warships to raft together with colliers and for coal to be manhandled aboard. Though arguments related to fuel security were made against such a change, the ease with which liquid fuel could be transferred led in part to its adoption by navies worldwide. One of the first ...
