Chinese Destroyer Nanjing (155)
''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. 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 was 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 closed in weapons system is composed of a H/PJ-12 short-range defense weapons system located in front of the bridge and a 24 Hongqi-10 air defense missile system located on the top of the hangar. They are combined to form a ladder interception. The original 100mm naval gun was replaced by a higher height and better stea ...

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] |
Type 518 Radar
The Type 518 radar is a Chinese high-performance L band long-range shipboard air surveillance radar. The Type 518 radar may be installed on destroyers or heavy tonnage naval vessels to detect long-range high-altitude aircraft in adverse natural noise and active electronic jamming environments. The Type 518 has been installed and deployed on the Luhu-class destroyer and the Type 052D destroyer. It is manufactured and exported by the Nanjing Changjiang Machinery Group Co Ltd (南京长江机器集团电子装备有限公司).

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 crossection 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 compatible with GJB 5860 VLS: *YJ-18 anti-ship cruise missile * YJ-21 anti-ship ballistic missile * HHQ-9 surface-to-air missile * CJ-10 land-attack cruise missile * CY-5 and Yu-8 anti-submarine rockets Ships classes with GJB 5860 VLS: * Type 052D destroyer * Type 055 destroyer See also * K-VLS - A vertical launching system of Republic of Korea Navy. * Mark 41 Vertical Launching System - A vertical laun ...

French 100 Mm Naval Gun
Modern French 100 mm naval guns are multipurpose artillery pieces, capable of a high rate of fire, against both aerial and surface targets. Most modern French warships are or were equipped with one of its variants. 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 ...

Type 052C Destroyer
The Type 052C destroyer (NATO/ OSD Luyang II-class destroyer) is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052C introduced both fixed active electronically scanned array (AESA) radar and vertically launched surface-to-air missiles into PLAN service,McDevitt: pages 59-60 making it the first Chinese warship with area air defence capability. 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 further ships were laid down until 2010;Li: page 44 the pause may have been due to the relocation of the shipyard.McDevitt: pages 59 By 2019, six were operational. 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. Stealth features are incorporated. The Type 052C uses predominantly Chinese systems derived from earlier foreign t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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) to e ...
