Marauder MUSV Begins On-Water Trials After Sub-Year Build

Saronic has launched its first Marauder Medium Unmanned Surface Vessel (MUSV), and begun on-water trials for the autonomous platform, designed to support dual-use defense and commercial operations far from shore.

Designed for sustained long-range missions, Marauder can operate fully autonomously or under remote human supervision without the additional requirements and operational risks associated with supporting onboard crew during extended deployments.

The vessel has a top speed of more than 25 knots and a range of up to 5,400 nautical miles. Marauder also features a 150-metric-ton payload capacity configurable for up to four 40-foot or eight 20-foot ISO containers, enabling operators to adapt the platform for logistics, research, maritime domain awareness, and persistent Intelligence, Surveillance, and Reconnaissance (ISR) missions without modifying the vessel itself.

Marauder is intended to provide persistent autonomous capability at scale on timelines suitable for fleet integration rather than one-off prototype deployment.

Alongside the vessel hardware, Saronic has developed a software-based fleet intelligence platform designed to provide operators with human-on-the-loop visibility into onboard autonomous operations in real time. The system continuously surfaces telemetry, vessel state, and subsystem status while supporting alerting, logging, and historical data replay for diagnostics and forensics.

Marauder was designed end-to-end for autonomy, with every hardware component featuring a software interface for monitoring, observability, and actuation. Operators can also remotely intervene in onboard autonomous processes when required.

Dino Mavrookas, Co-Founder and CEO of Saronic, commented, “I’m incredibly proud of our team for achieving this milestone. Designing, building, and launching an entire new class of ships in under a year is a feat the American shipbuilding industry hasn’t seen in generations. It’s what happens when design, production, and manufacturing are fully integrated under one roof. With multiple hulls already underway and our shipyard continuing to grow, this is what revitalizing American shipbuilding actually looks like — autonomous ships delivered at speed and scale, with the production capacity to back it up.”

The first Marauder hull progressed from initial design to on-water testing in less than one year at the company’s Franklin, Louisiana shipyard. The development model combines design, manufacturing, and autonomy development in-house to accelerate production timelines and enable faster iteration and decision-making.

The production approach incorporates modern aluminum shipbuilding techniques, including subassemblies designed for manufacturing speed, optimized production sequencing, modular construction methods, and commercial components intended to support rapid and repeatable production.

Production capacity at the Franklin shipyard is expected to expand by the end of 2026, enabling production of up to 20 Marauders annually. The second Marauder hull was flipped in March 2026 and is currently being outfitted with mechanical, electrical, and autonomy systems, while construction of the third and fourth hulls is already underway.

Work on the second hull is progressing 25 percent faster than the first as Saronic continues scaling what it describes as a repeatable production system designed to build operational fleets rather than standalone prototypes.
