The Type 055 destroyer (NATO/OSD designation Renhai-class cruiser) is a class of stealth guided-missile destroyers (rated as guided-missile cruisers per NATO/OSD standard parlance) constructed for the Chinese People's Liberation Army Navy (PLAN). It has a multi-mission design; the combination of sensors and weapons provides a main role of area air defence, with anti-submarine warfare capabilities surpassing previous Chinese surface combatants.

The Type 055 undertakes blue-water expeditionary missions and forms the primary escort for Chinese aircraft carriers. The United States classifies these ships as cruisers as the United States Navy (USN) defines a cruiser as a large multi-mission surface combatant with flag facilities; this suggests the U.S. expects the Type 055 to fulfill a similar role to the USN's .

Development The People's Liberation Army Navy (PLAN) 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.

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.Caldwell et al.: page 4

, the first ship of the class, began construction in 2014 at the Jiangnan Shipyard in Shanghai, and was commissioned on 12 January 2020. Its first public appearance—preceding commissioning—was during the PLAN's 70th-anniversary parade on 23 April 2019. When launched, Nanchang was the largest post-Second World War warship launched in East Asia.

The first batch of eight vessels to this design was laid down from 2014 to 2018, and all were in service by the end of 2022.Jane's Fighting Ships, 2023-24 Edition, ISBN 978-0-7106-3428 3, page 138. Further hulls under construction, observed by satellite imagery, including two at Dalian in January 2022, and two at Jiangnan, as part of a second batch of eight 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.

Satellite imagery in 2024 revealed that the ninth and tenth vessels of the class had been launched at Dalian and Jiangnan respectively, with the 11th and 12th units nearing launch at these two yards.

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. Chinese sources credit the design as being generally stealthy, with reduced radar, noise, infrared and electromagnetic radiation signatures.

Powerplants Propulsion is generated by four QC-280 gas turbines in combined gas and gas (COGAG) arrangement. Additional power may be provided by six QD-50 gas turbines.

The maximum flank speed is estimated to be .

Electronics 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.Caldwell et al.: page 9

Multiple sensors are housed inside the integrated mast and ship superstructure. 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 X-bandCaldwell et al.: page 8 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. Chinese sources claim the radar can be used to guide anti-satellite missiles.

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.

A deployment port exists for variable depth and towed array sonar, with a large bulbous bow likely contains a bow sonar.

Armament The primary armament is missiles carried in 112 vertical launching system (VLS) cells, 64 cells forward and 48 cells aft. The same VLS model is used on the Type 052D destroyer, which is believed to be an implementation of the GJB 5860-2006 standard; the GJB 5860-2006 is capable of hot and cold launches using concentric canisters. The Type 055 is expected to carry HHQ-9 surface-to-air missiles, YJ-18 anti-ship cruise missiles, CJ-10 land-attack cruise missiles, and missile-launched anti-submarine torpedoes upon entering service. Potentially, the larger cells may also carry anti-ship ballistic missiles.Caldwell et al.: pages 11-12 In December 2025, Chinese state media reported the test launch of the YJ-20 anti-ship ballistic missiles from the Type 055.

Additional armament includes a 130 mm main gun, an 11-barrel 30 mm close-in weapon system (CIWS), a HHQ-10 short-range air defense system, 324 mm torpedo launchers, and decoy launchers. There is hangar space for two helicopters.

Future developments It has been suggested that future variants may be armed with lasers or electromagnetic railguns, though since the current design does not have integrated electric propulsion, installation of integrated electric propulsion will be required for the ship to meet the estimated power requirements for such weapons in the future.

In 2021, the United States Department of Defense identified the Type 055 as the future launch platform for China's naval-based mid-course interceptors, such as the HQ-19 anti-ballistic missiles.

Operational history In April 2021, Nanchang operated with the aircraft carrier Liaonings escort group, and became the first Type 055 to be part of a carrier escort group.
