The Mission

The ocean is the largest sensing gap on Earth. Seasats builds solar-electric autonomous surface vessels - small enough to deploy by hand, rugged enough to run for months. The Lightfish flagship endures up to six months and 8,000 nautical miles; Quickfish sprints past 35 knots for tactical response; Heavyfish follows in 2026. Missions completed for defense, science, and commercial customers worldwide.
