Devil Ray T18
Unmanned Surface Vessel

The Devil Ray T18 is MARTAC’s compact, high-performance USV engineered to deliver persistent maritime capability where agility and endurance matter. Purpose-built for rapid response and sustained operations, the T18 bridges the gap between pocket-sized attritable assets and larger fleet nodes, bringing burst speeds over 60 knots, endurance, the stability of a catamaran and sensor persistence into a single, deployable package. It is also part of the high-performance catamaran design of the larger T24 and T38.

Built on a rugged, performance-optimized hull with low-profile, radar-aware shaping, the T18 minimizes detectability while delivering reliable seakeeping in demanding conditions. With a payload capacity of 750 lbs (341 kg) and an operational range of over 250 nautical miles, the platform balances meaningful payload options with true operational reach for extended ISR, target interdiction, over-the-horizon reconnaissance, and persistent perimeter defense missions.

Purpose-tuned propulsion provides rapid transit and stable on-station endurance, while the T18’s streamlined logistics footprint supports fast launch from ship, shore, or expeditionary platforms and reduces sustainment burden for deployed forces.

Integrated with MARTAC’s TASKER autonomy suite, the T18 operates across the full spectrum of control mode, fully autonomous, supervised, or remote operator, and can function as a single tactical node or a coordinated partner in distributed MantaFleet™ operations.

Compact, dependable, and tactically versatile, the Devil Ray T18 gives commanders a fast, persistent tool to extend awareness, complicate adversary defenses, and deliver repeatable effects where speed and persistence win.
