Type 051C Destroyer
The Type 051C destroyer (NATO reporting name: Luzhou class) is a long-range air-defence guided-missile destroyer built by China in its ongoing effort to create a true blue water navy. The ship uses the hull design of the older Type 051B (Luhai class), but is equipped with the advanced Russian S-300FM air defence missiles systems. Currently, two ships of this class have been launched and deployed by People's Liberation Army Navy North Sea Fleet. Background The construction of the Luzhou-class destroyer at China's northern Dalian Shipyard was revealed in 2004 with the help of Internet photographs. A disadvantage of the Type 051C is that it lacks the stealthier radar cross-section found on the newer Chinese warships. The ship also possesses less advanced steam turbine propulsion compared to gas turbine propulsion present in all newer Chinese destroyers. The Type 051C is a stop gap measure to provide long range area air defense to the fleet by mating the mature hull design with ...

Vladivostok
Vladivostok ( rus, Владивосто́к, a=Владивосток.ogg, p=vɫədʲɪvɐˈstok) is the largest city and the administrative center of Primorsky Krai, Russia. The city is located around the Zolotoy Rog, Golden Horn Bay on the Sea of Japan, covering an area of , with a population of 600,871 residents as of 2021. Vladivostok is the second-largest city in the Far Eastern Federal District, as well as the Russian Far East, after Khabarovsk. Shortly after the signing of the Treaty of Aigun, the city was founded on July 2, 1860 as a Russian military outpost on formerly Chinese land. In 1872, the main Russian naval base on the Pacific Ocean was transferred to the city, stimulating the growth of modern Vladivostok. After the outbreak of the Russian Revolution in 1917, Vladivostok was Allied intervention in the Russian Civil War, occupied in 1918 by White Russian and Allies_of_World_War_I, Allied forces, the last of whom from Japan were not withdrawn until 1922; by that tim ...

Ka-27
The Kamov Ka-27 (NATO reporting name 'Helix') is a military helicopter developed for the Soviet Navy, and currently in service in various countries including Russia, Ukraine, Vietnam, China, South Korea, and India. Variants include the Ka-29 assault transport, the Ka-28 downgraded export version, and the Ka-32 for civilian use. Design and development The helicopter was developed for ferrying and anti-submarine warfare. Design work began in 1969 and the first prototype flew in 1973. It was intended to replace the decade-old Kamov Ka-25, and had to have identical or inferior external dimensions compared to its predecessor. Like other Kamov military helicopters it has coaxial rotors, removing the need for a tail rotor. In total, five prototypes and pre-series helicopters were built. Series production started at Kumertau in July 1979, and the new helicopter officially entered service with the Soviet Navy in April 1981. The Ka-27 has a crew of three with a pilot and a navigator bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 ...

CIWS
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Examples of g ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.

C-803
The YJ-83 (; NATO reporting name: CSS-N-8 Saccade) is a Chinese subsonic anti-ship cruise missile. It is manufactured by the China Aerospace Science and Industry Corporation Third Academy.Gromley et al.: page 101 Description The YJ-83 uses microprocessors and a strapdown inertial reference unit (IRU); these are more compact than the equivalent electronics used in the YJ-8 and the export C-802, allowing the YJ-83 to have a 180-km range at Mach 0.9. The missile is powered by the Chinese CTJ-2 turbojet, and carries 190-kg high-explosive fragmentation warhead. Terminal guidance is by an active radar. The air-launched YJ-83K has a range of 180-km, a cruise speed of Mach 0.9, and a 165 kg high-explosive, semi-armour piercing warhead. The improved YJ-83KH uses a imaging-infrared seeker and has a range of 230 km; reportedly it may receive course corrections by remote link.Gromley et al.: page 102 The YJ-83 entered service with the People's Liberation Army Navy in 1998-1999 ...

Track-via-missile
Track-via-missile or TVM refers to a missile guidance technique which combines features of semi-active radar homing (SARH) and radio command guidance. This avoids the problems with terminal accuracy normally seen by command guided missiles, especially at long range. It has been used on a number of long-range surface-to-air missiles (SAMs) including the MIM-104 Patriot. Explanation Command guidance has the advantage of isolating most of the equipment for the missile guidance at the launcher, where size and weight are significantly less important. In these systems, the radar that provides guidance is on the ground or ship and the missile lacks an independent guidance system. Typically two radars are used, one tracking the target and another the missile, so that they can fly independent and widely separated paths. A computer then calculates the position and velocity of the two and calculates an intercept point. The same computer then calculates the control inputs needed to fly the mi ...

North Sea Fleet
The Northern Theater Command Navy (), or the North Sea Fleet (NSF; ) is one of the three fleets of the Chinese People's Liberation Army Navy, under the Northern Theater Command. In September 1950 the Qingdao Army Base was redesignated as a naval base. Following the departure of the Soviet Navy from Lüshunkou (Port Arthur), the North Sea Fleet was established in 1960 with naval bases in Qingdao and Lüshunkou. It includes the Aircraft carrier Liaoning, as well as nuclear-powered attack and missile submarines based at Qingdao bastion. The North Sea Fleet was historically the most capable of the Navy's three fleets, being the first in China to operate destroyers, shore-based missiles and nuclear submarines. In recent years however, the shift in strengthening of importance and strategic capabilities of the East and South Sea Fleets are more prioritised.
