Multi-Role Ocean Surveillance Ship
The Multi-Role Ocean Surveillance Ship (MROSS) is a type of research and surveillance ship in development since 2021 for the United Kingdom's Royal Fleet Auxiliary. The first ship, , is a commercial ship converted to the role which entered service in October 2023. The second ship is planned, potentially as a new build vessel. Both ships are to be used by the RFA to research and protect critical undersea national infrastructure, such as undersea cables and gas pipelines, in both British and international waters. Background With around 380 in use across the world, undersea cables play a key role in the global economy by carrying trillions of dollars worth in financial transfers and transmitting 97% of the world's global communications. The UK, like most countries, is heavily reliant on undersea cables for its telecommunications and so considers them part of its critical national infrastructure. Due to their importance, they represent a potential high value target of hostile state i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Ship
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] |
Cold War
The Cold War was a period of global Geopolitics, geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which lasted from 1947 until the dissolution of the Soviet Union in 1991. The term ''Cold war (term), cold war'' is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and Nuclear arms race, nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, Economic sanctions, embargoes, and sports diplomacy. After the end of World War II in 1945, during which the US and USSR had been allies, the USSR installed satellite state, satellite governments in its occupied territories in Eastern Europe and N ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Flight Deck
The flight deck of an aircraft carrier is the surface on which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese ''Akagi'' and battleship ''Kaga'', were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner which entered service in 1918. The armoured flight deck was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon Pool
A moon pool is an equipment deployment and retrieval feature used by oil platforms, marine drilling platforms, drillships, diving support vessels, fishing vessels, oceanography, marine research and underwater exploration or research vessels, and underwater habitats. It is also known as a wet porch. It is an opening found in the floor or base of the hull (watercraft), hull, platform, or chamber giving access to the water below. Because of its stable location, it safely allows technicians or researchers to lower tools and measuring instruments, instruments into the sea. Moon pools also provide shelter and protection so that even if the ship is in high seas or surrounded by ice, researchers can work in comfort rather than on a deck exposed to the elements. A moon pool also allows divers, diving bells, ROVs, or small submersible craft to enter or leave the water easily and in a more protected environment. Moon pools can be used in chambers below sea level, especially for the use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow Thruster
Manoeuvering thrusters (bow thrusters and stern thrusters) are transversal propulsion devices built into or mounted to either the Bow (watercraft), bow or stern (front or back, respectively) of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port (nautical), port or starboard side, without using the main propulsion mechanism which requires some Steering#Watercraft, forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect#Problems caused, Coandă effect. A stern thruster is of the same principle, fitted at the stern. Sufficiently large vessels often have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by e ...

Underwater Autonomous Vehicle
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs. Homing torpedoes can also be considered as a subclass of AUVs. History The first AUV was developed at the Applied Physics Laboratory at the University of Washington as early as 1957 by Stan Murphy, Bob Francois and later on, Terry Ewart. The "Self-Propelled Underwater Research Vehicle", or SPURV, was used to study diffusion, acoustic transmission, and submarine wakes. Other early AUVs were developed at the Massachu ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Birkenhead
Birkenhead () is a town in the Metropolitan Borough of Wirral, Merseyside, England. The town is on the Wirral Peninsula, along the west bank of the River Mersey, opposite Liverpool. It lies within the Historic counties of England, historic county boundaries of Cheshire, and became part of Merseyside in 1974. At the 2021 United Kingdom census, 2021 census, the built up area as defined by the Office for National Statistics had a population of 109,835. Birkenhead Priory and the Mersey Ferry were established in the 12th century. In the 19th century, Birkenhead expanded greatly as a consequence of the Industrial Revolution, leading to a shipbuilding firm which became Cammell Laird. A Great Float, seaport was established. As the town grew, Birkenhead Park and Hamilton Square were laid out. The first street tramway in Britain was built, followed by the Mersey Railway which connected Birkenhead and Liverpool through the world's first railway tunnel beneath a tidal estuary. In the sec ...

Cammell Laird
Cammell Laird is a British shipbuilding company. It was formed from the merger of Laird Brothers of Birkenhead and Johnson Cammell & Co of Sheffield at the turn of the twentieth century. The company also built railway rolling stock until 1929, when that side of the business was separated and became part of the Metro-Cammell, Metropolitan-Cammell Carriage & Wagon Company. History Formation from merger of Laird Company and Cammell & Co. The Laird Company was founded by William Laird (shipbuilder), William Laird, who had established the Birkenhead Iron Works in 1824. When he was joined by his son, John Laird (shipbuilder), John Laird in 1828, their first ship was an iron barge. John realised that the techniques of making boilers could be applied to making ships. The company soon became pre-eminent in the manufacture of iron ships and also made major advances in propulsion. In 1860, John Laird was joined in the business by his three sons, renaming the company John Laird, Sons & Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mothership
A mother ship, mothership or mother-ship is a large vehicle that leads, serves, or carries other smaller vehicles. A mother ship may be a maritime ship, aircraft, or spacecraft. Examples include bomber aircraft, bombers converted to carry experimental aircraft to altitudes where they can conduct their research (such as the B-52 carrying the X-15), or ships that carry small submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atlantis II carrying the DSV Alvin, ''Alvin''). A mother ship may also be used to recover smaller craft, or go its own way after releasing them. A smaller vessel serving or caring for ''larger'' craft is usually called a tender ship, tender. Maritime craft During World War II, the German Type XIV submarine or ''Milchkuh'' (Milk cow) was a type of large submarine used to resupply the U-boats. Mother ships can carry small submersibles and submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atla ...
