The gun on the trailer could provide Chinese land units with a terrifying defence against low-flying aircraft, cruise missiles, and possibly even artillery.

On display at AirShow China 2022 was the new LD-3000, also known as the Type 1130 Close-in Weapon Station (CIWS). A remotely controlled turret equipped with an 11-barrel 30mm Gatling design and mounted on a trailer with two axles makes up the CIWS.
The LD-3000 is a C-RAM (Counter Rocket Artillery and Mortar) system that is intended to defend critical facilities from aerial threats such cruise missiles, low-flying fixed-wing aircraft, and helicopters. The American-made C-RAM Centurion Phalanx and the air defence system appear to be extremely similar.
The LD-3000 employs a CIWS (Close-In Weapon Station), a ship-mounted seven-barreled 30 mm Gatling gun/Rotary cannon known as the Type 730, which is used by the Navy to defend against anti-ship missiles and other precision-guided weapons.
The LD-3000 is based on a two-axle trailer with a remotely controlled turret situated in the middle and a cabin housing a power generator in the back. A 30 mm Gatling gun/Rotary cannon with eleven barrels is mounted in the turret. The firing rate of the gun system is 12,000 rounds per minute.
With its sophisticated stabilisation system and radar, the turret’s 30mm gun weapon station can successfully intercept missiles travelling at Mach 4 90% of the time. Aerial targets can be detected and followed by the radar at a maximum distance of 15 km. A laser rangefinder, a colour TV camera, and an IR camera are also included in the CIWS system.A military 6×6 truck tows the LD-3000 CIWS trailer, which can be connected to a command and control operation centre built around a 6×6 truck.
