Type 348 Radar
Type 348 radar is a Chinese fire control radar developed for Type 76 twin 37 mm naval gun as CIWS, and it incorporates features of Italian RTN-10X and RTN-20X sold to China in 1992. Type 348 radar is frequently but erroneously confused and misidentified as another Chinese naval radar Type 346 due to the lack of publicized information in the development of the latter. Development To meet the urgent Chinese naval need of CIWS before the availability of more advanced CIWS such as Type 730 CIWS, Type 348 radar is developed as a stopgap measure by developing a less capable CIWS using Type 76 twin 37 mm guns. The muzzle velocity of twin 37 mm is 1 km per second, and the maximum rate is 800 round per minute, with a range of 3 km. However, early developmental trials have revealed that the original fire control radar Type 342 used proved to be rather inadequate in tracking sea-skimming anti-ship missiles, consequently, Type 348 radar was developed as a replacement, in ...

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 ...

Type 346 Radar
Type 346 radar is a highly digitized, multi-function, dual-band (S and C bands) naval active electronically scanned array (AESA) installed on Type 052C destroyers, Type 052D destroyers, Type 055 destroyers and Type 002 aircraft carriers of the PLAN. The radar is named as the Star of the Sea (Hǎi-Zhī-Xīng, 海之星) by its developer and it is one of the two competitors for PLAN’s SAPARS (Shipborne Active Phased Array Radar System) project/program. Due to its secrecy and lack of information, Type 346 radar has been frequently but erroneously confused with a Chinese fire control radar Type 348, and mistakenly identified as Type 348 by many sources. Furthermore, it is also frequently confused with and misidentified as Sea Lion series C-band phased array radars developed by another design house. Several models in the Type 346 series have been developed. When Star of the Sea was selected as the winner of SAPARS and accepted into Chinese service, it received the Chinese naval design ...

Type 730 CIWS
The Type 730 is a Chinese seven-barrelled 30 mm Gatling gun/Rotary cannon CIWS. It has a PLA Navy designation H/PJ12. It is mounted in an enclosed automatic turret and directed by radar, and electro-optical tracking systems. The maximum rate of fire is 5800 rd/m, and the effective range is up to 3 km. Development The gun is designed by the 713th research institute under the name 'Project 850' and is powered by two electric motors. The radar TR47C is a derivative of the EFR-1/LR66 J-band radar (NATO code name: Rice Lamp) by Xi'an Research Institute of Navigation Technology, but it is unclear that if this derivative is developed by the same institution. The OFC (Optical Fire Control)-3/H/ZGJ-4 electro-optical fire control system is designed by the Central China Optronic (electro-optical) Research Institute. Origin The system's primary purpose is defense against anti-ship missiles, and other precision guided weapons. However, it can also be employed against fixed/rot ...

Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''supersonic'' and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the shot.

Type 342 Radar
Type 342 radar is a Chinese fire control radar for HQ-61 SAM, and since has been retired from active service from Chinese navy (PLAN) when HQ-61 SAM is replaced by more advanced SAM systems. Type 342 is a centimeter wave, mono-pulse tracking radar for HQ-61 SAM. The radar was installed on Type 053K Jiangdong class frigate. Each radar is capable of engage a single target, and a maximum of three Type 342 radars can be installed on Type 053K frigate. Type 342 has been replaced by more advanced Type 345, as in the case onboard Type 053H2G frigate.

AK-630
The AK-630 is a Soviet and Russian fully automatic naval, rotary cannon, close-in weapon system. The "630" designation refers to the weapon's six gun barrels and their 30 mm caliber. The system is mounted in an enclosed automatic turret and directed by MR-123 radar and television detection and tracking. The weapon's primary purpose is defense against aircraft and helicopters. Effectiveness against anti-ship missiles and other precision-guided weapons is limited due to the limitations of the radar and aiming system and due to the dispersion of a short-barreled gun. The AK-630 can also be employed against ships and other small craft, coastal targets, and floating mines. Once operational, the system was rapidly adopted and installed in every new Soviet warship (from mine-hunters to aircraft carriers) with up to eight units on larger vessels; hundreds have been produced in total. Description The complete weapon system is called A-213-Vympel-A, which comprises the AK-630M Gun Mount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 054 Frigate
The Type 054 (NATO Codename Jiangkai I) is a class of Chinese multi-role frigates that were commissioned in the People's Liberation Army Navy Surface Force in 2005. They superseded the Type 053H3 frigates. Only two ships, ''Ma'anshan'' (525), and ''Wenzhou'' (526), were completed before production switched to the VLS equipped improved Type 054A frigate. Design The Type 054 has a stealthy hull design with sloped surfaces, radar absorbent materials, and a reduced superstructure clutter. The main anti-ship armament were YJ-83 sea-skimming anti-ship cruise missiles in two four-cell launchers. It retained the HQ-7 SAM, an improved version of the French Crotale, from the preceding Type 053H3; the HQ-7 had a ready-to-fire 8-cell launcher, with 16 stored in the automatic reloader. Short range defence was improved with four AK-630 CIWS turrets. A 100 mm main gun, also based on a French design, was mounted. Both ships were powered by four CODAD Type 16 PA6 STC marine diesel engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 347 Radar
The Type 347G "Rice Bowl" I-band fire-control radar is found on Chinese Navy ships, in conjunction with the Type 76A dual-37mm automatic AAA gun. Typically, the system includes 2 Type 347G fire-control radar with optical director, and 4 Type 76A guns. They're used on the Luda, Luhu, Luhai, Jiangwei class surface warships, as well as the Houjian, Houxin, and Haiging class patrol boats. Development Development for an air defense radar system begun in July 1974, with design finalized in August 1975, consisted of two radars, the 1st being a search radar designated as Type 347S with S stands for search, and a 2nd fire control radar for guns, designated as Type 347G with G as gun. Design was completed by the 723rd Institute in May 1976 and finalized in October 1977. In the 1980s, China imported the OTOBreda (now OTO-Melara) Twin Fast Forty AAand Selenia (now AMS) SPG-74 (RTN-20X) fire control system from Italy for evaluation. Although the Chinese navy didn't deploy the twin-40mm AAA, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
