An unmanned underwater vehicle (UUV) hovering upside down in a fast-moving current is not how most compact subsea systems are expected to operate.
But that is exactly the scenario AeroVironment is targeting with the Mission Specialist Wraith, a new UUV designed to deliver big-vehicle control in a small, rapidly deployable package.
Equipped with 10 vectored thrusters and true six-degree-of-freedom control, Wraith can maneuver and hold position in almost any orientation, including vertical, inverted, or rolled — all while maintaining stability.
Despite its compact size, it can carry a broad range of payloads, such as advanced imaging, navigation, and manipulation tools, making it suitable for missions spanning subsea inspection, defense tasks, and scientific operations.
Wraith follows VideoRay’s open-architecture design approach to enable rapid reconfiguration, seamless integration of third-party systems, and simplified field servicing.
With up to 80 pounds (36 kilograms) of thrust and lift, the UUV can move rapidly to a target area and remain on station even in challenging underwater conditions.
“Modern operations increasingly depend on access, awareness, and freedom of maneuver below the surface,” said Chris Gibson, Chief Executive Officer at VideoRay.
“Wraith gives forces a compact, rapidly deployable system that delivers the precision and control once reserved for much larger vehicles, helping operators extend reach, reduce risk to personnel, and respond faster in complex maritime environments.”
Deeper Dive on the Wraith
Weighing 220 pounds (100 kilograms), the UUV measures 52 by 31 by 14 inches (132 by 79 by 36 centimeters) and has an operating depth of up to 1,000 meters (3,300 feet).
Power comes from a universal input paired with a 400-volt direct current module, while onboard batteries provide up to 6 kilowatts of instantaneous power.
For situational awareness, Wraith uses a camera module capable of capturing high-resolution video and imagery, supported by onboard processing and storage to maintain a wide field of view.
Optional lighting modules, including dual adjustable light arrays, allow the vehicle to operate in low-light or near-dark conditions.
The UUV’s initial configuration marks the first step in a planned series of upgrades, with future iterations expected to expand payload capacity, endurance, and overall system flexibility.
