Design

The Type 052C used the same hull and propulsion as the preceding Type 052B destroyer, which had also been built by Jiangnan. While the Type 052B used a mixture of Russian and Chinese systems, the Type 052C used predominantly Chinese systems, with a few sensors being notable exceptions.

Electronic countermeasures

The digital and solid state Type 726-4 decoy launcher system is mounted on the forward deck and consists of four launchers. Each launcher has 18 tubes arranged in three six-tube rows. Firing is typically controlled automatically by the combat data system, but a manual control console is also provided. The decoy launcher system may theoretically be linked to other subsystems, although whether this feature is incorporated in the Type 052C is unknown.

The primary role of the Type 726-4 is to launch chaff and decoys. However, atypically, it may also fire ASW rockets (against submarines, torpedoes, and frogmen), and even be used for shore bombardment.

The launchers on the Type 052C appear to be manually loaded; automatic reloaders exist for the Type 726-4.

Electro-optical (Optronics)

The OFC (Optical Fire Control) -3 electro-optical fire control system is a modular design that is consisted of a laser range finder, a color TV camera, and an IR camera, and the laser range finder can be replaced by a laser designator (for the laser beam riding SAM), the TV camera can be replaced by a night vision camera, and the IR camera can be replaced by an ImIR, at higher cost. Development to incorporate the dual band IR, night vision camera, and the color TV camera has been successfully completed, but it is unclear if these newly developed versions will be installed on any of the ships. The OFC-3 optronics is designed by the Central China Optronic (electro-optical) Research Institute. Although the advanced versions have been successfully tested, only the most basic version have been installed on board Type 052C class, as acknowledged by the developer, and domestic Chinese media rumored the main reason was to reduce the cost. However, the adaptation of the most basic version of OFC-3 results in great decrease in the performance and effectiveness of the main gun, because without the laser designator needed, laser beam riding and semi-active laser guided projectiles can not be deployed for the Type 210 100 mm naval gun

The JRSCCS integrated command and control system is used to direct both the OFC-3 and IR-17. In addition, the system can also be used to direct all on board weaponry and sensors, though as only an emergency backup measure for the combat data system, which JRSCCS integrated command and control system is linked to. The JRSCCS system is full automatic and only require a single operator when necessary. The operator console of the JRSCCS is designated as JRMC and is consisted of two multifunction color displays and a joy stick, and up to five JRMC consoles can be deployed when required. According to the developer, such five consoles arrangement as the emergency backup of combat data system is located separately from the main combat information center
Combat Information Center
The Operations Room is the tactical center of a warship or AWAC aircraft providing processed information for command and control of the near battle space or 'area of operations'...

 where the combat data system is located to ensure survivability, but it is not known for sure if this configuration had been adopted for Type 052C destroyer.

Like the H/ZBJ-1 combat data system on board, the JRSCCS is distributed and redundant and reflects both Russian and Western influence. From the Russian/Soviet tradition, each sensor handles as much of its own data processing as possible. While this potentially allows the design of individual system components to be simplified, the Chinese followed the Western tradition by ensuring central components can still process all information from the sensors in the event of sensor hardware malfunction. The cost of such redundancy is such that half the price of the ship is in its C4I systems. Another Western design tradition incorporated was the use of an open architecture software design.

 weaponry on board Type 052C destroyer is mainly for self-defense, since it is a class of air-defense destroyer. The ship is equipped with hull-mounted SJD-8/9 medium-frequency hull-mounted active–passive sonar, which is a development of French DUBV-23 sonar, and the improvements in both the hardware and the software over the original French design enabled the sonar to be used as a torpedo approaching warning system as well. When in active mode, the range of the hull-mounted sonar is at least 12 km or greater, and when in passive mode, the range is at least 60 km or greater, a 20% increase to the 50 km maximum range of the Russian–Soviet MGK-355 Platina sonar on board Sovremenny class destroyer

s. Encrypted underwater telephone and other communication gears are installed on board to enable this class to be better coordinated with submarines in joint maneuvers.

Although both variable-depth sonar such as ESS-1 medium-frequency VDS (the Chinese development of French DUBV-43 VDS) and towed-array sonar were successfully tested on board, these were abandoned because incorporating these extra sonars would lead to significant redesign of the hull and increased cost. Despite the fact that the extra processing capability reserved in the combat data system for the towed sonar and VDS when needed, it is highly unlikely that the towed sonar and VDS would ever be incorporated in the near future. The high frequency obstacle–mine avoidance sonar once originally planned to equip this class failed to materialize due to the same financial concern of reducing the cost.

Two models of airborne dipping sonars can be carried by on board Ka-27 helicopters, both being the derivatives of Russian / Soviet V-3 medium frequency (MF) Ros' sonar (also known as Rys, with NATO reporting name

Original sonars on board Ka-27 were Russian VGS-3K models marketed by Morfizpribor, while Chinese military enthusiasts have claimed (but yet to be confirmed) that H-3 models of Ukrainian firm Sokol is also purchased by China to diversify supplier sources. Unconfirmed claims by Chinese military enthusiasts also suggest that Russian firm Morfizpribor is actively marketing its 180 kg class Vesta-K low frequency (LF) airborne sonar to China as an upgrade to the original VGS-3K Ros' sonar, which would significantly boost the performance by increasing the range by tenfold to 50 km, and with greater operating depth to 700 meters. However, the drawback of Russian–Soviet airborne sonar is that the information gathered cannot be processed on board the aircraft, so the process in done on board the ship instead.

. The developers of both the JRSCCS and the combat data system have claimed that their products could handle the information needed to control UAVs. However, it is highly unlikely that any long range UAVs will ever be deployed on board this class because the complete handling system to support these large UAVs would need the entire hangar, thus displacing the only helicopter on board. Chinese governmental media, however, did release photos of a variety of propeller driven light UAVs being launched from destroyers and claimed that these light UAVs could be deployed on every destroyer class currently in Chinese service, and some of the pictures have depicted some UAVs carry laser targeting pods, providing guidance for laser guided projectiles. However, as of mid-2007, it still can not be confirmed that if any light UAVs has been on board Type 052C class on a regular basis. The lack of regular deployment of UAVs on board only seems to confirm the claim that the laser guided projectiles for the main gun are not deployed due to the lack of associating guidance equipment. On August 17, 2008, another type of UAV named as Hummingbird carrying electro-optical pod were deployed on board for the successful test of a new data link developed by China Northern Co. (中国北方公司). The new data link is a two-way real-time encrypted data link designed to replace the current HN-900 data link, and it is designated as NCTDL, short for Naval Common Tactical Data Link. The new data link is claimed by many Chinese to be at least equal to the Link 16

, but such claims have yet to be verified by both the Chinese government and sources outside China. However, it is certain that the new data link will replace HN-900 currently in service on board PLAN ships.

Depth charge
A depth charge is an anti-submarine warfare weapon intended to destroy or cripple a target submarine by the shock of exploding near it. Most use explosives and a fuze set to go off at a preselected depth in the ocean. Depth charges can be dropped by either surface ships, patrol aircraft, or from...

 helicopter can operate in all weather conditions up to 200 km from the host ship, but its onboard dipping sonar only has half the range of the Chinese copy of the French dipping sonar on board Z-9, furthermore, it lacks the processing capability to process the information gathered, so the information has to be passed back to the host ship for processing via data links, while in contrast, Z-9 can process the information gathered on board the helicopter, but with shorter range.

Although the sensors and weaponry carried by both helicopters are somewhat comparable to their western counterparts, the overall capabilities as ASW platforms for these helicopters are seriously hampered due to the installation of their radars: unlike the western belly-mounted radars with 360-degree coverage, the radars for Ka-28 and Z-9 are chin-mounted and nose-mounted respectively, thus creating huge blind spots. In order to overcome these blind spots, Ka-28 and Z-9 must fly in very complicated flight patterns, resulting in significant fuel consumption, thus decreasing the endurance and range in comparison to western ASW helicopters.

A total of eight units were originally purchased and Chinese sources have claimed that all had been upgraded, mainly in the area of turbine blade production techniques, and such update had greatly increased reliability and maintainability. The main parameters of DA80/DN80 included:
  • length: 6.4 meter

  • Height: 2.7 meter
  • Weight: 16 tons
  • Efficiency: 36.5%
