The Chinese People's Liberation Army (PLA) sending advanced warships including the Type 055 large destroyer Nanchang, the Type 052D destroyer Kunming, the Type 054A frigates Binzhou and Liuzhou, and the Type 903A comprehensive supply ship Dongpinghu, as well as fixed-wing anti-submarine warfare aircraft and vessel-borne helicopters from the Eastern, Southern and Northern Theater Commands, while Russia will deploy large anti-submarine ships, frigates, and aircraft.

The Type 052D destroyer (Luyang III-class destroyer) is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force. The Type 052D is a larger variant of the Type 052C; the Type 052D uses a canister-type, instead of revolver-type, vertical launching system (VLS) and has flat-paneled active electronically scanned array (AESA) radar. The new VLS is not limited to surface-to-air missiles, making the Type 052D China's first dedicated multi-role destroyer.

The powerplant is a combined diesel or gas (CODOG) system with two 28-megawatt (38,000 hp) QC-280 gas turbines and two 6 MW (8,000 hp) MTU 20V 956TB92 diesel engines. The machinery drives two shafts for a maximum speed of 30 knots (56 km/h; 35 mph).

The Type 052D is equipped with Type 346A AESA and Type 518 L-band radar. The destroyer is also equipped with both variable depth (VDS) and linear towed array sonar. The VDS is deployed through a hinged opening in the transom by a hydraulic lifting mechanism. The VDS body is a streamlined fairing fitted with Y-shaped hydrodynamic vanes for towing stability.
