About the Company

Seasats

Autonomous surface vessels for defense, research

Seasats builds long-endurance autonomous surface vehicles for defense, research, and commercial use. Its flagship Lightfish is a solar-powered ASV that can be deployed by one or two people from a pickup, runs for up to six months, travels about 8,000 nautical miles, and carries modular payloads for ISR and environmental monitoring; Quickfish is a high-speed interceptor, and Heavyfish is planned for larger missions. The vessels operate autonomously using solar power and navigation software to collect data and perform missions without onboard crews. Seasats differentiates itself with portable, long-endurance platforms and modular payloads, backed by real-world missions and government contracts, aiming to provide persistent maritime capability that lowers operating costs and expands reach for defense, science, and commerce.
