Description
The Devil Ray T38 is an unmanned surface vessel manufactured by Maritime Tactical Systems (MARTAC) of Florida for the United States Navy and export customers.
The vessel features a carbon-fibre hull and operates as an autonomous surface platform. It is designed to perform intelligence, surveillance, and reconnaissance, maritime domain awareness, logistics support, and distributed fleet operations. The platform's design supports both high-speed burst transit and low-speed, endurance-focused profiles.
The United States Navy deploys the T38 in the Middle East under Task Force 59, where the vessel has conducted live-fire exercises with the Fifth Fleet. In May 2026, a T38 completed a fully autonomous mission off the coast of California, which included operating on alternating single-engine profiles offshore under varying sea state conditions. The Philippines also operates smaller variants from the same design family, including the Mantas T-12.
