Compact long-endurance autonomous surface vessel for persistent maritime domain awareness, survey, research, and security missions.
Lightfish is a dual-use USV platform developed by Seasats in the United States. Seasats positions the vessel as a compact, modular, long-endurance autonomous surface vehicle for maritime domain awareness, ISR, hydrographic survey, environmental monitoring, and security patrol missions. Public company specifications describe a hand-deployable craft with a length of about 3.5 m, top speed of 5 kn, payload capacity of 66 lb (29.9 kg), up to 6 months of endurance, and range described by Seasats as up to 8,000 nautical miles under its long-range operating profile. The platform uses solar-electric power with hybrid reserve, redundant communications, collision avoidance, and supervised autonomous mission control for persistent ocean operations.
Official Seasats materials describe Lightfish as hand-deployable, self-righting, operational in Sea State 6, and capable of multi-month missions with solar-electric power and hybrid reserve.
