YJ-18

The YJ-18 (, NATO designation CH-SS-NX-13 ) is a Chinese anti-ship cruise missile.

Description
The United States believes the YJ-18 is similar to, or is a copy of, 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. Performance estimates include a range of 290 nmi, with a threat ring of 264,200 nmi2, and a cruising range of 180 km at Mach 0.8 and a sprint range of 40 km at Mach 2.5 to 3.0.

The missile can be launched from vertical launching systems, and possibly from submarine torpedo tubes. Chinese media claims the missile has an inertial guidance system using BeiDou Navigation Satellite System data, and carries a 300 kg high-explosive warhead or an anti-radiation warhead to destroy electronics at short range.

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-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. A land-based version could replace the subsonic 400 km-range YJ-62 with shore batteries.
