Chinese Destroyer Nanjing
''Nanjing'' (155) is a Type 052D destroyer of the People's Liberation Army Navy. She was commissioned on 2 April 2018. Development and design The basic ship type and layout of the ''Type 052D'' guided-missile destroyer is the same as that of the Type 052C destroyer, but compared to the earlier Type 052C destroyer, the Type 052D superstructure has a larger inclination angle and provides better stealth performance. At the same time, the helicopter hangar is moved from being on the left side of the hull to the center axis of the ship; a pair of small boat storage compartments were added on both sides of the hangar, similar to the design on the Type 054A frigate. The close in weapon system is composed of a H/PJ-12 short-range defense weapon system located in front of the bridge and a 24 Hongqi-10 air defense missile system located on the top of the hangar, which is combined to form a ladder interception. The original 100mm naval gun was replaced by a higher height and better ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 pennants ...

GJB 5860-2006
GJB 5860-2006 () is a Chinese military technical standard describing a vertical launching system (VLS) for all types of missiles aboard surface combatants. Cells have a square crosssection with sides, and may be , , or deep. Each cell carries one missile; the shortest cell may carry four missiles. Hot and cold launches are supported; hot launching uses the concentric canister launch (CCL) approach with exhaust vents within each launch cell. The first operational implementation is believed to be the VLS aboard the People's Liberation Army Navy's Type 052D destroyer. Armament what VLS can use: *YJ-18 anti-ship missile *YJ-21 anti-ship missile *HHQ-9 SAM *CJ-10 land-attack cruise missiles *Missile-launched anti-submarine torpedoes See also * Mark 41 Vertical Launching System The Mark 41 Vertical Launching System (Mk 41 VLS) is a shipborne missile canister launching system which provides a rapid-fire launch capability against hostile threats.

French 100 Mm Naval Gun
Modern French 100 mm naval guns are multipurpose artillery pieces, capable of a high rate of fire. Most modern French warships are or were equipped with one of its versions. History At the end of the Second World War, the French Navy was equipped with guns of numerous calibres, most of which were obsolete. In 1953, the STCAN of Paris, under engineer Tonnelé, drafted the design of a multi-purpose 100 mm gun. The gun was designed to be effective for anti-aircraft defence, anti-ship combat, and shore bombardment fire support. The first model of the family, "modèle 53", was tested at sea on the escort ''Le Brestois'' in 1958 and the escort aviso ''Victor Schoelcher'' in 1961. Description The most common version, ''modèle 68'', features a completely automatic action and control. The ammunition is stored in a magazine underneath the turret, and fed to the gun by a lift operated by a team of two. A flexible pipe allows feeding the gun under any orientation. Rounds of amm ...

Type 054A Frigate
The Type 054A (NATO/ OSD Jiangkai II) is a class of guided-missile frigate from the People's Republic of China. It is a development of the Type 054 frigate; compared to its predecessor, the Type 054A has medium-range air defense capability in the form of Type 382 radar and vertically launched (VLS) HHQ-16 surface-to-air missiles.Schwartz (2015): page 28 The Type 054A entered service with the People's Liberation Army Navy (PLAN) in January 2008,''Jane's Fighting Ships'' (2015): page 144 and was a key component of the PLAN's surface fleet by the late 2010s.Willett (2019): page 24Willett (2019): page 26 Production was ongoing in 2021. Design The Type 054 was heavily influenced by the from France, and so reflected the strategic and operational requirements of that country. The development of the Type 054A may have been driven by China's need to address high-intensity armed conflict.Collins et al. (2014): page 2 The Type 054A uses the same stealthy hull form as the Type 054. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 052C Destroyer
The Type 052C destroyer (NATO/Office of the Secretary of Defense, OSD Luyang II-class destroyer) is a ship class, class of guided-missile destroyers in the China, Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052C introduced both fixed active electronically scanned array (AESA) radar and vertical launching system, vertically launched surface-to-air missiles into PLAN service,McDevitt: pages 59-60 making it the first Chinese warship with area air defence capability. , six of these destroyers had been built and were operational. Program The first two ships, and , were laid down at the Jiangnan Shipyard in Shanghai in 2002, and entered service in 2004 and 2005 respectively. No new ships were laid down until 2010;Li: page 44 the pause may have been due to the relocation of the shipyard.McDevitt: pages 59 Design The Type 052C appears to share the same basic hull design as the Type 052B destroyer, which in turn is based on the Type 051B destroyer.

People's Liberation Army Navy
The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology. Until the late 1980s, the PLAN was largely a riverine and littoral force (brown-water navy). In the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying overland border disputes. Traditionally subordinated to the PLA Ground Force, PLAN leaders were now able to advocate for a renewed attention towards the seas. Chinese military officials have outlined plans to operate in the first and second island chains, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 052D Destroyer
The Type 052D destroyer (NATO/ OSD Luyang III-class destroyer) is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy. The Type 052D is a larger variant of the Type 052C; the Type 052D uses a canister-type, instead of revolver-type, vertical launching system (VLS)Li: page 44 and has flat-panelled active electronically scanned array (AESA) radar.McDevitt: page 62 The new VLS is not limited to surface-to-air missiles, making the Type 052D China's first dedicated multi-role destroyer. Etymology Chinese media informally calls the Type 052D the Chinese Aegis, portraying it as a peer of contemporary United States Navy ships equipped with the Aegis Combat System.Holmes: page 4 The appearance of the Type 052D, with flat-panelled radar and canister-based VLS, has encouraged this informal use. Design Sensors The Type 052D is equipped with Type 346A AESA and Type 518 L-band radar. The Type 052D is also equipped with both variable depth (VDS) and linear tow ...

Combined Diesel Or Gas
Combined diesel or gas (CODOG) is a type of propulsion system for ships that need a maximum speed that is considerably faster than their cruise speed, particularly warships like modern frigates or corvettes. For every propeller shaft there is one diesel engine for cruising speed and one geared gas turbine for high speed dashes. Both are connected to the shaft with clutches; only one system is driving the ship, in contrast to CODAG systems that can use the combined power output of both. The advantage of CODOG is a simpler gearing compared to CODAG, but it needs either more powerful or additional gas turbines to achieve the same maximum power output. The disadvantage of CODOG is that the fuel consumption at high speed is poor compared to CODAG. CODOG vessels * MGB 2009, a modified Motor Gun Boat of the Royal Navy (1947), and *The two German torpedo boats ''Pfeil'' and ''Strahl'' (''Vosper'' class, 1963-65) *The US Navy s (built 1966-1971) *The US Coast Guard s (from 1967) *s ...

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 ...
