Unmanned Surface Vessel

Available Now in Full Production!


Currently, The MANTAS T12 is MARTAC’s most popular MANTAS system and is available in full production. With a length of 12 feet (3.6 meters) and a maximum payload capacity of 140 lbs (64 kgs), it’s a solid system for littoral environments, hosted from a mothership or nested within Devil Ray Systems. The sixth-generation propulsion is highly reliable with thousands of hours of continuing operations worldwide.

Equipped with an all-electric powertrain and payload management system, the T12 ensures clean and sustainable operations, aligning with modern environmental standards. Deployable from shore, ship or boat with supporting launch and recovery equipment, the T12 has the capability of long duty cycles performing the dull, dirty and dangerous missions you may require. The MANTAS T12 also comes in an optional gator configuration whereby the hull floods to decks awash level allowing for low observable stealth missions.

The MANTAS T12 has the same control system as all other MANTAS and Devil Rays and can integrate above and below-surface sensors such as EO/IR cameras, sonars, Lidars, and acoustic modems to expand your mission opportunities.
