The Haikou (171) is a modern missile destroyer of the People's Liberation Army Navy (Chinese Navy), part of the Type 052C-class (Lanzhou-class) of surface fighting ships intended primarily for fleet air defense. The class was born through a September 2001 government commitment to which the Haikou hull eventually succeeded the initial Lanzhou (170) at the Jiangnan Shipyard of Shanghai. Haikou was officially launched on October 30th, 2003 and formally commissioned in 2005. The hull was forged from a modular initiative which allowed it to be shared between the similar Type 052B-class destroyer family (Guangzhou-class) - differing primarily in their armament and system fittings - for a more cost-effective procurement process. Four Type 052C destroyers have been completed to date (2013) as the Lanzhou (170), Haikou (171), Changchun (150) and Zhengzhou (151) with as many as two more (Jinan 152 and Xi'an 153) remaining under construction.
The Haikou displaces at 7,000 tons and features a running length of 154 meters, a beam of 17 meters and a draught of 6 meters. Power is served through a CODOG arrangement - "COmbined Diesel Or Gas" - which allows for bursts of speed beyond normal cruising. The propulsion system is made up of 2 x DA80/DN80 series gas turbines (of Ukrainian origin, the UGT-25000) of 48,600 shaft horsepower coupled to 2 x Shannxi diesel engines (a local copy of a German MTU Friedrichshafen design) of 8,840 horsepower collectively developing up to 57,400 shaft horsepower for a maximum speed (in ideal conditions) of 30 knots. Each vessel in the class is complemented by 280 crew made up of officers and enlisted personnel.
Externally, design of the Haikou is conventional featuring an unobstructed forecastle, centralized primary superstructure and low-set rear secondary superstructure. As with most all modern destroyer/frigates in service or entering service, the Haikou makes use of an extremely clean side profile which improves the radar cross-section of the vessel. The smoke funnels are coupled together in low-profile structures amidships while the main deck gun is clearly identified at the forecastle with the vertical launch system (VLS) direct aft of this emplacement. The bridge is located at the frontal highpoint of the main superstructure and is capped by an enclosed pyramid-style main mast containing the primary sensors, radar, communications and fire control facilities.
As a missile-carrier, the Haikou is outfitted with 48 x HHQ-9 series long-range surface-to-air missiles (a variant of a Chinese land-based missile development) seated in 8 x 6-cell Vertical Launch Systems. This provides the vessel with a wide-arcing defensive anti-aircraft net suitable for protecting the heart of the Chinese fleet when at sea. As with most modern destroyers/frigates, the Haikou also fields anti-ship missiles through a pairing of 8 x YJ-62 launchers (2 x 4-cell cylindrical launchers) while underwater threats are countered through 6 x 533mm torpedo launchers. For close-in surface threats and offshore bombardment operations supporting amphibious assaults, the Haikou showcases an automatic 100mm DP (Dual-Purpose) deck gun based on the French Creusot-Loire T100C along with 2 x 30mm Type 730 Close-In Weapon System (CIWS) autocannons (one located fore and the other aft).
The Haikou was completed with a Type 348 four-array multifunction Phased Array Radar (PAR). The vessel is also given a point defense suite that includes 4 x 18 tube-launched rocket decoys. Many of the onboard systems of the Haikou and her class are of Chinese origination allowing for less reliance on foreign goods. Fire control is handled by the MR 331 series FC radar system.
The aft portion of the vessel is reserved for the integrated flight deck which can launch and receive medium-class helicopters while the available hangar allows for on-the-spot maintenance and repair. The primary helicopter in use is the indigenous Harbin Z-9C (or similar) or the Soviet-Russian all-weather submarine hunter / anti-ship warfare navalized Kamov Ka-28 "Helix". There is also growing onboard support for the launching and retrieving of UAVs (Unmanned Aerial Vehicles).
As of this writing (2013), the Haikou retains an active status in the Chinese fleet.
