Type 052 Luhu Class Destroyers

Chinese PLAN (1991) – 2 ships: Harbin, Qingdao

Chinese transition destroyers: The Luhu clas destroyers constituted in 1993 a significant improvement over the Luda class, a domestic design that approached the capabilities of Western detroyers, but made to achieve this goal extensive use of foreign technologies still accessible to the PRC before the 1989 incident and subsequent ban. They were also the first Chinese DDs to use gas turbine engines, and to be fitted with a a integrated combat system. Although impressive compared to previous designs, it must be compared to the contemporary Arleigh Burke and Kongo designs.

The Luhu class destroyers was the first class studied as a replacement for the old Luda class prior to the end of the cold war. There has been waves of modernizations meanwhile, up to the point of creating brand new sub-classes, thanks to the 1980s opening to the West and rapid updates to the standards of western electronics. This bring a real value to ships that were at first closely modelled on the Soviet early Kotlin class destroyers. The “Luda II and III classes” were a continuation of the famous Luda class of the 1970s, modernized in several batches. They were in service by 1992. But the fleet was ageing fast, and by the 2000s, decommissions started (By 2007, the Jian and Xi’an sticken, Changsha in 2008, and four more in 2012-2013.) as new units entered service, notably of the Luhu (Type 052) and Luhai classes (Type 51B).

The Luhu class only counted two ships, imatriculated 112 and 113, the Harbin (At first called by th West Zhanjiang) and Qingdao. They were a massive improvements over the previous design, in particular in terms of tonnage (almost doubled), and were designed from the keel up to integrate the latest Western electronics and armaments. It was a quantum leap in technology, that announced the future catching up of the Chinese PLAN, more in accordance to the will to built a powerful blue water navy (Today’s PLAN budget is only second to the US Navy) capable of projections of power far away from the traditional Chinese sphere of influence and not only as a defensive naval force.

The Luhu class integrated a much larger hull, modern CODOG propulsion and diesels, modern SAMs, artillery, ASW missile system, and moreover a large hangar for two ASW helicopters. The design was more in line of what types of Destroyers the JSDNF used to put at sea and operate. They were however still lightyears from the contemporary Kongō-class destroyer, using AEGIS, just launched at that time. The Luhu appears now like a transitional design, still stuck very much on the cold war. Both were launched in 1991 and 1993 (probably laid down in 1989 and 1990 at Jiangnan yard and in service by 1994 and 1996.

Design development and overview

Basically the new class was an enlargement of the Luda class, at first planned to integrate US electronics and weaponry and even a General Motors gas turbines and propulsion system. However the 1989 embargo after the Tian-an-Men massacre ruined all these prospects and had severe consequences of supplies afterward. According to Conways 1947-1994 volume, released at that date, both ships plans had to be entirely redrawn to comprise new equipment, like possibly Russian-designed gas turbines, and “probably equipped with the Chinese-versions of the french Tavitac 2000 CDS”. In fact, as it is known today, both ships were eventually equipped as planned with General Electric LM2500 gas-turbines and German MTU diesels, while the electronics comprised indeed a Thomson-CSF TAVITAC and local systems, plus local armament, with the exception of the HQ-7 SAM, a close copy of the French Crotale short SAM system.

Both ships had been significantly upgraded in 2011 and were considered the best Chinese destroyers before the building and transfer from Russia of four Sovremenny class destroyers. They are now eclipsed by the 8500 tons Type 052B/C/D Luyang class destroyers.


Both ships had been planned by the China Warship Design Institute (former Seventh Academy of the defence Ministry) to be built at Jiangnan Shipyard. Blueprints were elaborated under the supervision of the Chief designer was academician Mr. Pan Jingfu (潘镜芙). French-made radars and fire-control systems and General Electric gas turbine engines were concerned, being delivered already before the ban. However even with Western technology, there was still no adequate shipborne air defense systems. Surface-to-air missiles deployed indeed had a visual-range targeting system only limitiog operations to the land-based aircraft action range, condemning any blue water policy. The Luhu destroyers like the Jiangwei class frigates were both conceived to end this state of affairs by adopting the modern HQ-7 SAM quite an improvements, but still, short range and using visual range (WVR). By contrast the latest Type 052D destroyers combines the HHQ-9 long range, HQ-16 medium range and DK-10A and HHQ-10 short range SAMs to cover a very large cone around the ship.

General Characteristics

As built the ships were 4,800 tons standard (5,700 tons fully loaded according to Conway’s), for a length of 144 m (versus 132 m on the Luda), a beam of 16 m (versus 12.8m) and a draught of 5.1 m (versus 4.39m) and was propelled by a pair of General Electric LM2500 gas turbines CODOG, delivering 55,000 shp (53.600 for Conways), coupled with two MTU 12V1163 TB83 diesels, delivering 8840 bhp for 20 knots in cruise, and 5000 nautcal miles in range at 16 knots. The only let down was the top speed, that passed from 32 knots (Luda) to 30 knots (Conways). Complement range was comprised between 260 and 300 (Conways). 260 seems more reasonable given the figures of the better automated Type 052D (280). In general shape, the ships are a clear departure of the largely WW2-style segmented approach of the Luda, with alternating missile launchers instead of torpedo tubes banks.

On the electronics side, both ships received re-labelled foreign equipments of various European origins, with extensive documentations still written in English, French, Italian or German. Type 756 radars1, MX-9022, Thomson-CSF Sea Tiger3, Hai Ying4, Thomson-CSF DRBC-32F5, and Type 347G6, plus a bow-mounted sonar and VDS.

5-Thomson-CSF DRBC 32F: Standard weapon-direction system used for Crotale (HQ-7 SAM) missiles.
Critics about the lack of electronic warfare capabilities was answered in 2011’s refit of the ships, with the adoption of two Type 726-4 122mm 24-tube decoy launchers, installed on both sides of the forward bridge.


Anti-Ship: Four quadruple 4 YJ-83 (C-803) anti-ship missiles
Anti-Air: Octuple cell HQ-7 SAM (8+16 rounds)

C-803 (NATO CSS-N-8 Saccade): A 715 kg, 6.392 m by 36 cm anti-ship missile. Derived from the Chinese YJ-8 (C-801) with extended range of 350 km. They are fitted in pairs of oblique-mounted launchers behind the funnel, and fore and aft of the rear antenna mast. Developed by the China Haiying Electromechanical Technology Academy it is closely based on the Exocet missile both in general shape, operatory mod and capabilities. It is small enough to be airborne as well. This turbojet missile operates at 3–5 m altitude when attacking and 5–7 m when cruising at Mach 0.9, uses Inertial and terminal active radar and carries a 285 kg time-delayed semi-armour-piercing high-explosive payload.

HQ-7 SAM: Also used by the PLAGF (Land Forces), the HQ-7 (hóng qí or “red flag”/”red banner”) is a short-range air defense missile closely based on the French Crotale defence system developed by Thomson-CSF in 1978-1979 and imported for “evaluation”. Both the missile and launcher, and the Sea Tiger radars were comprehensively reverse-engineered. Production started in 1988. The HQ-7 is 85 kgs and can reach an operational altitude of 30–5,000 m (98–16,404 ft), carrying at Mach 2.3 an HE-Frag warhead while the radar detecting range was 18.4 km (HQ-7/FM-80). It was replaced by the HQ-16.

NATO reception and experts opinion

When the ship was operational, and although it was a clear departure over previous designs with many modern features, its operational capability were called into question by analysts. As a good will gesture when making a stop, US Naval officers were allowed on board, inspecting the No. 112 Harbin in 1997 (two years after the ship went into service) taking many photos in the process. It appeared from these that the ships were mainly intended as technology demonstration vessels rather than fully operational, combat-ready destroyers. Indeed with many foreing equipments from turbines to diesels, electronics, and equipments still still labeled in the language of the country of origin and probably also the documentation the crew’s abilities to deal with these systems in a stressful conditions were perceived then as arguably doubtful.

Harbin prior to the 2011 modifications

Those equipments also were never designed to operate together so integration was poor. There are clues that the next Luhai-class was specifically designed to address theses issues (but seems to have been not very successful either). At the same time the ships were considered still lacking modern electronic warfare and electronic counter-measures capabilities. However the 2011 refit was meant to deal with all these issues. In fact according to Chinese medias themselves and internet sources, the Luhu-class is indeed used as comparative technological demonstrators since both ships had different foreign systems.

Indeed Harbin was given a Raytheon AN/SQS-56 sonar, and Italian DE-1164 integrated sonar system and the Qindao was given a French Thomson-CSF DUBV 23/43 HMS/VDS sonar. Both were replaced by different Chinese sonar systems SJD-7 and SJD-9. The first also had the ZKJ-3 (ZKJ-III) based on the Italian designed IPN-10 combat data system SADOC-2 while the second had the ZKJ-4, based on the French Thomson-CSF TAVITAC. In 2011 they were replaced by the ZKJ-4A/B.

The 2011 Upgrades

The Type 052 destroyers were upgradedin drydock, with many modifications, like the Type 76A dual-purpose guns replaced by two Type 730 CIWS on top of the helicopter hangar. The HHQ-7 SAM could have been replaced also by another system better suited against sea-skimming AShMs and on the electronic and active defence side, two Type 726-4 decoy launchers were installed on the forward bridge. Also system integration issues were solved for the most with the adoption of a new indigenous C3I system, the ZJK-4B and the Type 518 Hai Ying radar by the Type 517M long-range air search radarwhile the Type 362 air/surface radar was replaced by the Type 364 and SATCOM antennas added, plus the modifications described above. Thanks to these the ships went on a more active carrer. The Qindao was mated with the Type 054A frigate Yantai and supply ship Weishanhu to form the 11th Chinese naval escort flotilla operating in 2012 against Piracy in Aden and along the Somali coast. It was relieved by the Harbin, mated with the Type 053H3 frigate Mianyang and same supply ship (12th naval escort flotilla) in 2013-2014. In 2013 also Qingdao participated in the International Fleet Review 2013 in Sydney where she was abundently photographed. Both ships are regularly featured in the Chinese medias up to these days, but they are considered by all as transitional destroyers. Both are active with the North Sea Fleet.
