Jiangnan Shipyard is currently building two new 6500t class multipurpose missile destroyers for the PLA Navy. The ships, reportedly designated Type 052B, are likely based on the hull design of the Type 051B (Luhai class) destroyer, but fitted with Russian surface-to-air missile (SAM) and fire-control radar systems.
Compared to the PLA Navy�s current Type 052 (Luhu class) and Type 051B (Luhai class) destroyers, the new Type 052B destroyers possess much better air defence capabilities, which comprises two Russian-made SA-N-12 Grizzly medium-range SAM launchers and two indigenously developed Type 730 close in weapon systems (CIWSs). Despite the lack of more sophisticated systems such as the phased array radar and vertical launch system (VLS), the destroyers are generally capable of providing limited medium-range fleet air defence.

PROGRAMME
The Type 052B is the PLA Navy�s yet another major procurement programme following the purchase of two Russian-built Sovremenny class missile destroyers in 1999 and 2000. The existence of programme like this suggests that despite the warship purchase deals with Russia, China is unlikely to depart from the self-reliance policy to reply on domestic shipbuilders to design and build modern and sophisticated warships. In fact, imported technologies are being integrated into indigenous designs to save the development costs and time.
The two ships have been built at Jiangnan Shipyard, Shanghai since 2000. The first ship (pennant number 168) was launched in May 2002, followed by the second ship (pennant number 169) in January 2003. Currently the two ships are stationed in Jiangnan Shipyard for weapon and other equipment installations. If the serial numbers of these ships are genuine, they will be deployed in the PLA Navy South Sea Fleet.

DESIGN
The displacement of the ship is about 6,500 tonne, which is roughly comparable to the Russian-made Sovremenny class. Compared to the Type 051B (Luhai class) destroyer introduced in 1999, the Type 052B apparently incorporates even more stealth features -- the sides of the vessel are sloped to minimise radar cross section, surfaces have been coated in radar-absorbent paint and the profiles of external features have been reduced. There is a stern helicopter flight deck and a hanger which can accommodate two Russian Ka-28 Helix-A ASW/SAR helicopters.

WEAPONS
The main air defence weapon systems onboard the Type 052B are two (1 front and 1 rear) Russian-made SA-N-12 Grizzly medium-range SAM launchers, guided by four Front Dome indication radars and a Top Plate 3D air-search radar. For short range air defence, two indigenous Type 730 CIWS similar to the Dutch Goalkeeper are located on both sides behind the bridge.
The 100mm single-barrel main gun on the front deck seems to be a copy of the French Creusot-Loire 100 mm gun. Four 4-cell YJ-83 (C-803) anti-ship missile launchers are fitted at midship behind the funnel. In addition, four unique multiple rocket launchers (MRLs) are fitted on the front deck to launch decoys, antisubmarine rockets, and land-attack ammunitions.
PROPULSION
The propulsion system in the form of CODOG consists of two Ukraine-made DA80/DN80 gas turbines and two indigenous diesels.
