Unveiled in November 2018 at Air Show China, the L30 and L80 USVs have been designed by the Zhuhai-based company to perform a wide range of security and defense tasks.
The smaller L30 Security and Patrol USV has a length, width, and height of 7.5 m, 2.7 m, and 4.2 m, respectively. Its main tasks include patrolling, reconnaissance, SAR and anti-terrorism. During a recent Intelligence Security drill organized by the Chinese Ministry of Public Security, the L30 USV “successfully completed tasks including patrol, evidence collection and high-speed pursuit,” Yunzhou Tech explains.
The L30 is powered with a pair of diesel engines that gives it maximum speed of 46 kt with an endurance of around 300 nautical miles.
The biggest L80 USV is 12.12 meters long, 3.8 m wide and 1.62 m high. It features a maximum speed of 38 kt and an endurance of 170 nautical miles with an economic speed of 26 kt. According to Yunzhou, the L80 would be mainly deployed for patrolling, reconnaissance, SAR, CBRE detection, or even anti-terrorism in shallow waters border defense.
Both L30 and L80 are made of fibre-reinforced plastic. They integrate a range of common mission systems, such as an undisclosed model of stabilized remote-controlled weapon station and Yunzhou’s in-house autopilot and anti-collision software. The two models are also equipped with a mast-mounted EO/IR ball turret incorporating a laser rangefinder, as well as unknown communication systems.
