About
About Seasats
Seasats’ Lightfish is a solar-electric autonomous surface vessel for persistent ocean sensing. The 11.4-foot craft combines solar generation, a small auxiliary generator and a 4 kWh battery with a composite hull and retractable keel. It cruises at roughly 2 knots, can reach 4.5 knots and is designed for multi-month missions covering more than 6,000 nautical miles while carrying customer-selected sensors.
A library of more than 50 payload integrations supports hydrographic survey, acoustic monitoring, environmental science, communications and defence missions. Operators plan and monitor deployments remotely, while onboard autonomy handles navigation and vessel health over long periods and through intermittent connectivity. The wider Seasats range includes smaller Quickfish and larger Heavyfish systems, allowing customers to choose endurance and payload capacity around the mission. Lightfish is portable enough for deployment without major ship infrastructure and interoperates with external command-and-control systems as one node in a distributed maritime network.

Timeline
Events
- 2026-10-02 - Market Signal - Seasats Lightfish border pilot informs possible Pentagon vessel expansion
Ten vessels are currently being tested after the pilot began in January. A possible Gulf radar-monitoring network would extend from Texas to Key West. The proposed expansion is incremental and vendor-agnostic; no additional Seasats award is confirmed.
Source - 2026-09-04 - Contract Award - Seasats books more than $24M of Lightfish orders
The disclosed total represents funded customer commitments rather than ceiling values on contract vehicles. The order mix includes direct Lightfish procurement and Robot-as-a-Service contracts for long-endurance maritime autonomy. Seasats identified the U.S. Marine Corps and U.S. Navy among the customers receiving Lightfish systems for multiple mission sets.
Source - 2026-05-27 - Capability - Seasats Lightfish completes autonomous Taiwan Strait transit
The Lightfish crossed the full length of the Taiwan Strait over five days while monitoring vessel traffic. Its onboard cameras captured imagery of Chinese naval vessels during the transit. The voyage exercised long-range autonomous maritime surveillance in a contested, high-traffic operating environment.
Source - 2026-03-17 - Demonstration - Seasats Quickfish USV completes continuous eight-day sea trial
Seasats announced the successful completion of an eight-day continuous sea trial for Quickfish. The test emphasized the platform's mix of 35+ knot sprint speed, multi-week designed endurance, and modular mission configuration. The update strengthened the case that Quickfish is progressing from launch story toward practical defense and security use.
