Type 055 destroyer
The Type 055 destroyer (NATO/OSD Renhai-class cruiser) is a class of guided missile destroyers being constructed for the Chinese People's Liberation Army Navy Surface Force. It is a multi-mission design; the combination of sensors and weapons suggests a main role of area air defence, with anti-submarine warfare capabilities surpassing previous Chinese surface combatants.

The United States classifies these ships as cruisers. The United States Navy defines a cruiser as a large multi-mission surface combatant with flag facilities; this suggests the U.S. expects the Type 055 to fulfil a similar role as the Ticonderoga-class cruiser.
The People's Liberation Army Navy was interested in a large destroyer from at least 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.
The first ship began construction in 2014 at the Jiangnan Shipyard in Shanghai, and launched on 28 June 2017. When launched, it was among the largest post-Second World War warships launched in East Asia, and the largest surface combatant launched by China.
The Type 055 adopts a conventional flared hull with distinctive stealthy features including an enclosed bulbous bow 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 amidship increases internal volume and reduces radar cross-section. The smoke stack 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.
Propulsive power is generated by four 28 MW QC-280 gas turbines in combined gas and gas arrangement. Additional power may be provided by six 5 MW QD-50 gas turbines.
The integrated mast may mount X band radar in four fixed active electronically scanned arrays (AESA). The deckhouse may mount four Type 346B AESA panels; the previous Type 346 was a dual S and C band radar, but the Type 346B may only be S band as a X band radar is included. The X band radar may be mounted higher as it is better suited for horizon search and low altitude object detection. The Type 346B arrays can be larger and have higher power when mounted on the deckhouse below the X band radar.
Various electronic warfare support measures (ESM), electronic countermeasures (ECM), and electro-optic (EO) sensors and datalinks are mounted. They are likely more advanced than those deployed on previous ships.
A deployment port exists for variable depth and towed array sonar. The large bulbous bow likely contains a bow sonar; the Type 055 may mount a larger bow sonar than previous Chinese surface combatants.
The primary armament are missiles carried in 112 universal vertical launch cells (VLS); 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 longest variant, with 9-metre cells, is likely used. 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.
It has been suggested that future variants may be armed with lasers or electromagnetic railguns. 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.
The universal VLS makes it possible to carry future anti-ballistic missiles (ABM).
