Type 003
''Fujian'' (18; ), named after Fujian province, is the first of the Type 003 class aircraft carrier (NATO/ OSD Fujian-class CV), and is currently fitting out. Built for the People's Liberation Army Navy (PLAN), ''Fujian'' was launched on 17 June 2022 and is China’s first fixed-wing aircraft carrier with a fully indigenous design, featuring a CATOBAR system and electromagnetic catapults. The Type 003 class was originally unofficially called Type 002 when , China's then-incomplete second carrier, was believed to be designated Type 001A. ''Shandong''s official designation, Type 002, was revealed during commissioning. Observers hence believed the third carrier will be Type 003. Design The Type 003 is expected to use steam turbines and electromagnetic catapults, whereas preceding Chinese carriers launched aircraft with ski jumps. For CNS Fujian's propulsion system, its structure is still not very clear. According to Chinese military commentator Song Zhongping, the system has " ...

Fujian-class Tanker
Fujian-class tanker is a class of naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN), and has received NATO reporting name Fujian class. The exact type designation still remains unknown, and a total of twenty of this class have been confirmed in active service as of early-2020s, both in transport oil tanker and water tanker versions. Fujian class ships in PLAN service are designated by a combination of two Chinese characters followed by a three-digit number. The second Chinese character is You (油), meaning oil in Chinese, because these ships are classified as oil tankers. The first Chinese character denotes which fleet the ship is service with, with East (Dong, 东) for East Sea Fleet, North (Bei, 北) for North Sea Fleet, and South (Nan, 南) for South Sea Fleet The Southern Theater Command Navy (), or the South Sea Fleet (SSF; ) is one of the three fleets of the Chinese People's Liberation Army Navy, operating in the South China Sea und ...

Ski-jump (aviation)
In aviation, a ski-jump is an upward-curved ramp that allows aircraft to take off from a runway that is shorter than the aircraft's required takeoff roll. By forcing the aircraft upwards, lift-off can be achieved at a lower airspeed than that required for sustained flight, while allowing the aircraft to accelerate to such speed in the air rather than on the runway. Ski-jumps are commonly used to launch airplanes from aircraft carriers that lack catapults. It is believed that the first use of the ski-jump occurred during the Second World War, where a temporary ramp was added to to assist the take-off of heavily laden Fairey Barracudas conducting a strike mission against the German battleship . During the Cold War era, the concept was studied as a means of reducing the length of flight decks required for future aircraft carriers as well as to facilitate ever-increasingly heavy aircraft at sea. The Royal Navy took a particular interest in the ski-jump during the 1970s, conducting a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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" (or "load lines"). A mer ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Flight Deck
The flight deck of an aircraft carrier is the surface from 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 . The armoured flight deck was another innovation pioneered by the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ...

Keel
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rear Admiral
Rear admiral is a senior naval flag officer rank, equivalent to a major general and air vice marshal and above that of a commodore and captain, but below that of a vice admiral. It is regarded as a two star "admiral" rank. It is often regarded as a two-star rank with a NATO code of OF-7. The term originated in the days of naval sailing squadrons and can trace its origins to the Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear admiral the most junior admiralty of many navies. In most European navies, the equivalent rank i ...
