Evidence & current status
Navy use is identified by the supplier. Published test claims are attributed; speed, range and payload maxima are not assumed simultaneous.
The T38 is the larger operationally documented member of MARTAC's current Devil Ray product line. Its carbon-fibre catamaran provides deck space for interchangeable sensors and mission equipment. It belongs alongside, but is not identical to, the smaller MANTAS and other Devil Ray models.
In May 2026 MARTAC reported an eight-day autonomous mission by a T38 owned and operated by the US Naval Air Warfare Center Weapons Division at Point Mugu. The activity supported the Navy's sea-range instrumentation programme. The company describes extended open-ocean operation without an onboard crew or escort, making this more specific evidence than a display model or proposed procurement.
The current manufacturer page gives a 12.2-metre length and a burst speed above 50 knots. Older descriptions can use the nominal 38-foot name and different speed claims. The endurance demonstration prioritised persistence, so it must not be read as eight days at burst speed. Manufacturer-reported range and environmental results remain specific to the tested configuration and operating conditions.
