The
People's Liberation Army Navy was interested in a large destroyer from as early as the late-1960s. A development program, code-named "055", initiated in 1976 was cancelled in 1983 after encountering insurmountable technical obstacles from industrial underdevelopment; for example, the required gas turbine power plants could neither be produced domestically nor imported at acceptable prices.[23]
In April 2014, an image emerged of a full-scale mock-up of the Type 055 superstructure—with enclosed integrated mast for radar and other electronics—at the Chinese naval electronic testing range in
Wuhan.[24][25]
Nanchang, the first ship of the class,[26] began construction in 2014 at the Jiangnan Shipyard in Shanghai,[3] and was commissioned on 12 January 2020.[2] Its first public appearance—preceding commissioning—was during the PLAN's 70th-anniversary parade[26] on 23 April 2019.[6] When launched, Nanchang was among the largest post-
Second World War warships launched in East Asia.[27][28]
The first batch of 8 vessels to this design were all laid down in 2014 to 2018, and all were in service by the end of 2022.[29] Further hulls were observed under construction, including two at Dalian in January 2022, by satellite imagery, and two at Jiangnan, as part of a second batch of 8 vessels (to reach a total of 16) under procurement provided for in the
14th Five Year Programme (2021–2025), aimed to equip all three Fleets.[29][5]
Satellite imagery reveals that the 9th and 10th vessels of the class have been launched at Dalian and Jiangnan respectively, with the 11th and 12th units nearing completion at these two yards.[30]
Design
Stealth
The Type 055 adopts a conventional
flared hull with distinctive
stealthy features including an enclosed
forecastle that hides mooring points, anchor chains, and other equipment. The bow and main deckhouse are configured similarly to previous
Type 052C/
D destroyers. A continuous structure located amidships increases internal volume and reduces radar cross-section. The smokestack design reduces both infrared signature and radar cross-section.[8] Chinese sources credit the design as being generally stealthy, with reduced radar, noise,
infrared, and electromagnetic radiation signatures.[31]
Power plants
Propulsive power is generated by four 28 MW QC-280 gas turbines in
combined gas and gas (COGAG) arrangement. Additional power may be provided by six 5 MW QD-50 gas turbines.[8]
Chinese literature suggests that the Type 055 is capable of "facilitat[ing] command management of a battlegroup and supporting elements". The command-and-control and battle management systems are likely comparable to contemporary PLAN systems, which reflect over a decade of intensive interest in information integration from the late 2000s.[32]
Multiple sensors are housed inside the integrated mast and ship superstructure.[13] The class has a dual-band radar system; four S-band
Type 346B Dragon Eye active electronically scanned array (AESA) panels are mounted on the superstructure, and four smaller[33] X-band[12] panels are mounted on the mast. The Type 346B panels are estimated to be 40% larger than the Type 052D destroyer's Type 346A panels, for greater transmission power and sensitivity.[33] Chinese sources claim the radar has anti-stealth capability[34] and can be used to guide anti-satellite missiles.[33]
The ship structure also contains navigation radars, various communication and intelligence systems,
electronic warfare support measures (ESM),
electronic countermeasures (ECM), electro-optical (EO) sensors, laser-warning systems, optronic jammers, and datalink systems. They are likely more advanced than those deployed on previous ships.[13][8]
A deployment port exists for
variable depth[8] and
towed array sonar.[8][12] The large bulbous bow likely contains a bow sonar;[12][8] the Type 055 may mount a larger bow sonar than previous Chinese surface combatants.[8]
It has been suggested that future variants may be armed with lasers or
electromagneticrailguns.[8] Since the current design does not have
integrated electric propulsion, installation of integrated electric propulsion will be required for the ship to meet power requirements in the future.[39]
In 2021,
United States Department of Defense identified Type 055 as the future launch platform for China's naval-based mid-course interceptors, such as the
HQ-19 anti-ballistic missiles.[40]
