The LM450 is a compact, multirole USV with omnidirectional thrusters for agile, redundant propulsion. Its modular deck supports sonars, ROV/AUV launch systems and UAV docking, enabling environmental monitoring, defense/security and seafloor mapping. It operates remotely or semi‑autonomously via satellite or 5G, carries over 300 kg and stays on mission for weeks.
Features
Redundant Propulsion
Self-Righting Hull
Precision GNSS
Redundant Communication
Flexible Payload Bay
Long Endurance
Tri-State Hybrid
Semi-Autonomous
Rugged, long‑endurance USV featuring built‑in redundancy for added reliability and endurance
Deployment & Recovery of UAVs
Supports the deployment of small unmanned aerial surveillance systems, providing a reliable hub for both power and communications.
Made for ease of transport
The LM450 is designed to fit inside a standard 20-ft shipping container, making transport simple and cost-effective. Its compact footprint and modular design mean it can be shipped globally using conventional freight services, reducing logistics complexity and enabling rapid deployment anywhere in the world
