Overview

The LM450 is a compact, multirole Unmanned Surface Vessel (USV) designed for extended offshore missions. It features omnidirectional thrusters, self-righting hull, and a modular deck supporting sonars, ROV/AUV launch, and UAV docking. It operates remotely or semi-autonomously via satellite or 5G, carries over 300 kg payload, and stays on mission for weeks. Endurance options include up to 6 months with DockMaster, 30 days hybrid, or 34 hours pure electric.
