VideoRay Mission Specialist Defender

The Mission Specialist Defender configuration is designed for more precise control of the vehicle position and orientation, heavier payloads, and demanding intervention, such as rendering unexploded ordinance safe or cleaning nets for offshore fish farms.

With seven thrusters, the Defender is able to move in any direction, and maintain active pitch to face the vehicle in an upward or downward orientation. The addition of third party control and navigation software from Greensea Systems or Seebyte makes the Defender a popular configuration for dangerous or heavy-duty missions.



The VideoRay Mission Specialist Series (MSS) Remotely Operated Vehicles (ROVs) are customizable and flexible platforms that use a system of interchangeable, modular components. The topology of MSS ROVs provides a platform which can be easily adapted to target specific missions. The philosophy behind the MSS is fitting each system to the exact sensors, tools, depth rating, and thrust needed for the job at hand, rather than retrofit accessories to a standard ROV.


The modularity of VideoRay’s Mission Specialist technology allows for easy maintenance, fast repairs, simple upgrades, and seamless integration across configurations. Each configuration consists of several modules developed by either VideoRay or a variety of underwater tool and sensor companies. Modules include cameras with a range of resolutions, LED lighting, efficient yet powerful thrusters, power systems ranging from 75 Volts to 1600 Volts, communications modules using either fiber or copper, manipulators, positioning and sensors for radiation, water quality, and metal thickness, imaging and multibeam sonars. Since integration with third party modules is a primary goal, the wide range of power, communication, and mounting options accommodate almost every compact tool or sensor.
