Description

The United States believes the YJ-18 is similar to,^[5] or is a copy of,^[4] the Russian 3M-54 Klub. According to the United States Department of Defense, the YJ-18 has a subsonic cruise mode and a supersonic terminal attack.^[5] Performance estimates include a range of 290 nautical miles (330 mi; 540 km),^[6] with a threat ring of 264,200 sq nmi (349,900 sq mi; 906,000 km²),^[3] and a cruising range of 180 km (110 mi; 97 nmi) at Mach 0.8 and a sprint range of 40 km (25 mi; 22 nmi) at Mach 2.5 to 3.0.^[4]

The missile can be launched from vertical launching systems,^[7] and possibly from submarine torpedo tubes.^[4] Chinese media claims the missile has an inertial guidance system using BeiDou Navigation Satellite System data, and carries a 300 kg (660 lb) high-explosive warhead with an anti-radiation seeker.^[8]

The YJ-18 is deployed aboard the Type 052D destroyer and the Type 055 destroyer. It may already be carried by the Shang II-class nuclear attack submarine outfitted with VLS cells, will replace the 20 nmi (23 mi; 37 km)-range YJ-82 aboard the Yuan-class air-independent propulsion (AIP) and Song-class diesel-electric submarines, will likely deploy on the Type 095 submarine, and may be capable of deployment on Kilo-class submarines.^[6][3] A land-based version could replace the subsonic 400 km (250 mi; 220 nmi)-range YJ-62 with shore batteries.^[3][4]
