Type 052B or Guangzhou Class 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.

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 with a range of 38 km. Most military analysts expect the Guangzhou class to be similar to the Russian Sovremenny class destroyer in terms of general performance. The displacement of the Type 052B is 5850 tons. The ship features a “low point” design combined 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.

The Type 052Bs are equipped with two missile launchers, one forward and one aft on the ship. These launchers can launch the SA-N-12 Grizzly Surface-to-Air Missile. Each launcher has two dedicated MR-90 Front Dome fire control radars and carries a total of 48 missiles. They also haves 4 quad YJ-83 Anti-Ship Cruise Missile launchers located amidships. For guns there is a 100mm cannon in ‘A’ position and this is 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. The Type 052B is equipped with four 18-barrel Type 724 chaff launchers for part of its self-defense suite.

Weapon Systems

The Type 052B destroyer is armed with two Russian-made surface-to-air missile launchers, one on the front deck behind the 100mm main gun, and one on top of the helicopter hanger. The launchers can fire the latest 9M317 Shtil (NATO codename: SA-N-12 Grizzly) semi-active, radar-homing, medium-range air defence missile. The missile uses the ship’s Russian-made Fregat M2EM Top Plate 3D circular scan radar for target acquisition, and the Front Dome (two radar for each launcher, each radar with two guidance channels) indication radar for missile guidance. Up to three missiles can be aimed simultaneously. The range is up to 38km against aircraft and 20km against anti-ship cruise missile. The ship carries 48 missiles.

Four 4-cell launcher for the YJ-83 (C-803) sea-skimming, radar-homing anti-ship cruise missile system are installed behind the funnel. The YJ-83 is said to have a final approach speed of Mach 1.5 and a maximum range of 150km. It was noted that the YJ-83 onboard the Type 052B relies on a Russian-made Band Stand fire-control radar to provide target information, which would enable the YJ-83 to reach its maximum range of fire without relaying target information by the shipborne helicopter.

The Type 052B destroyer was the first PLA Navy warship to be fitted with the CIWS. There is a seven-barrel 30mm Type 730 CIWS installed on each side of the bridge. The weapon system has a maximum rate of fire of 4,600~5,800 rounds/min.

The ship also has a single-barrel 100mm gun developed by 713 Institute on the basis of the French Creusot-Loire T100C design. The gun can be used against surface targets and air targets such as aircraft and low speed missile, with a maximum rate of fire of 90 rounds/min. The gun can be operated in fully automatic mode from the radar control system, from the shipborne optical sighting system, or laid manually. The turret design incorporates strong radar cross-section reduction features.

The Type 052B destroyer is fitted with two triple 324mm Yu-7 (Mk-46 Mod 1) antisubmarine torpedo tubes and two Type 75 twelve-barrel 240mm antisubmarine rocket launchers. Range is up to 1,200m. The rocket is armed with a 34kg warhead. Additionally, the destroyer has four 18-barrel multiple rocket launchers (MRLs) installed on the front deck. The purpose of these MRLs remains unknown but is thought to be used to launch antisubmarine rockets, ground- attack rockets and/or decoys/chaffs.

Radar

The Type 052B uses a Fregat-MAE-5 (Top Plate) 3D search radar, mounted at the top of the forward mast. Four MR90 Front-Dome radars provide fire control for the SA-N-12 missiles. A Type 344 fire control radar controls the main gun. A bandstand radar provides fire control for the YJ-83 ASCM missile.

Sensors

The air search radar is a Russian Fregat M2EM (NATO codename: Top Plate) 3D air search radar operating at D/E band. The radar has a maximum detect range of 230km to aircraft and 50km to sea-skimming missile. There are four (in contrast to six on Sovremenny class) Russian Front Dome fire control radar (F band) for the 9M38 air defence missile. The main gun and anti-ship missile are controlled by the Russian Band Stand radar.

Command and Control

The ZJK-5 combat system onboard the Type 052B is thought to be an improved variant of the Type 051B (Luhai class)’s ZJK-4-3A. The ZJK-5 is based on the 1553B military data bus and the 100Mbps Ethernet technology. The multi-channel defence suite is capable of engaging several targets simultaneously.

Aviation

The destroyer’s stern hanger accommodates one Kamov Ka-28 (NATO codename: Helix) antisubmarine warfare (ASW) helicopter. Carrying various weapons including torpedoes and deep charges, the helicopter can operate in all weather conditions up to 200km from the host ship. Alternatively, the destroyer can carry an indigenous Z-9C helicopter.

Propulsion

The Type 052C’s propulsion is in the form of CODOG, consisting of two Ukraine-made DA80/DN80 gas turbines rated at 48,600hp and two Shaanxi diesels (Chinese copy of the MTU 20V956TB92) rated at 8,840hp (6.5 MW).
