Type 052B destroyer

Type 052B destroyer

The Type 052B or "Guangzhou" class destroyer (NATO reporting name: "Luyang" I class) is a class of multirole missile destroyer built by the People's Republic of China. Two ships have been built, with "Guangzhou" (168) and "Wuhan" (169) both being commissioned into the PLAN in July 2004. This class features a stealthy hull and significantly improved air defence systems, an area that had been a major weakness on previous ships designed by China. These ships represent a major improvement over the older generation vessels and reflects PLAN's need to have a modern destroyer.

Programme

Due to the weak air defence found on most Chinese warships, the People's Liberation Navy ordered the construction of a new type of vessel capable of providing sufficient air defence. This resulted in the construction of the Type 052B ("Guangzhou" class) multirole missile destroyer. The Type 052B is built with considerable Russian technology including the Russian-made 9M38 Buk-M1-2 (NATO codename: SA-N-12 Grizzly) air defence missile system, an extremely effective air defence system equipped on all Russian destroyer after the late 80s. This new SAM system gives a boosted air defense range of 25km to 38km. Most military analysists expect the "Guangzhou" class to be similar to the Russian Sovremenny class destroyer in terms of general performance. [ [http://www.globalsecurity.org/military/world/china/luhai.htm Luhai - People's Liberation Army Navy ] ] The chief designer of this class is the academician Mr. Pan Jingfu (潘镜芙), who is also the designer of the previous two classes.

The modern capabilities of this vessel demonstrate the Chinese desire to build up their blue-water navy and ability to project force into deeper waters. This shows a strong internationally-influencing naval force is being developed and will be a force to contend with in the future.

Design

The displacement of the Type 052B is 5850 tons (revealed by an official news on Jul 24, 2007, slightly less than the previously estimated 6500 tons). The ship features a "low point" design and combines this with radar absorbing paint to reduce radar signature. The ship's funnel incorporates cooling devices to reduce infrared signatures. The stern flight deck can host a Kamov Ka-28 ASW helicopter. [ [http://www.sinodefence.com/navy/surface/type052b_luyang.asp Type 052B Luyang Class Missile Destroyer - SinoDefence.com ] ]

The Type 052Bs incorporate an extensive array of weapons systems. She is equipped with two missile launchers, one forward and one after on the ship. These launchers can launch the SA-N-12 Grizzly Surface-to-Air Missile. Each launcher has 2 radars dedicated to it. The ship carries a total of 48 missiles. She also has four, 4-cell C-803 Anti-Ship Cruise Missile launchers located after of the ship's funnel. For guns she has a 100mm cannon on the bow and this is also the first PLAN vessel to be equipped with a Close-In Weapons System, or CIWS. For sub-surface threats, she is armed with 2 triple 324mm Yu-7 Anti-Submarine torpedo tubes and two type 75 twelve-barrel 240mm antisubmarine rocket launchers. Interestingly she is equipped with four 18-barrel multiple rocket launchers (MRLs), whose purpose is as of yet undefined. Possibly these MRLs are used for shore bombardment or "hedgehog-like" anti-submarine depth charges.
