At Zhuhai Airshow 2012, the LD-2000 Close-In Weapon System (CIWS) Air Defense System was marketed by China North Industries Corporation (NORINCO). Designed to engage aircraft, helicopters, unmanned aerial vehicles, cruise missiles and other precision guided munitions with a Radar Cross Section (RCS) of at least 0.1 m^2 in a dense Electronic Counter Counter-Measures (ECCM) environment against multiple targets at close range.
The LD-2000 system can be used to defend high-value targets such as Command and Control (C2) centers, ballistic
missile launchers, Surface-to-Air (SAM) missile systems. It can be integrated with other Air Defense Systems, such as the HQ-7, HQ-16 and HQ-9 to form a multi-layer Integrated Air Defense System (IADS) as observed in Chinese service, including the Air Defense garrison protecting Hong Kong.
Each combat vehicle is mounted on a 8 x 8 truck with a land based version of the naval H/PJ-12 Close-In Weapon System (CIWS), mounted to the rear. It consists of a seven-barrel 30 mm gatling gun turret with a maximum fire rate of 4200 rounds per minute and a maximum effective range of 3500 m. The turret holds 2 magazine rounds with 500 rounds each. One with High Explosive Incendiary (HEI) rounds and another with Frangible Armour Piercing Discarding Sabot (FAPDS) rounds.
Each vehicle has a tracking radar with a range of 18 kilometers against targets with a RCS of 2 m^2. This drops to 9 kilometers against a RCS of 0.1 m^2. A combined television/infrared tracking system with a range of about 5 kilometers is also included.
