The Defender delivers a powerful blend of performance, adaptability, and control—making it a trusted choice for complex underwater operations. Designed to excel in high-risk, high-precision environments, it helps operators work more safely, efficiently, and confidently, whether inspecting offshore infrastructure, navigating confined spaces, or supporting subsea interventions.
Thanks to its six-axis control and powerful thruster configuration, the Defender allows users to maintain accurate positioning in difficult environments—reducing operator fatigue and improving mission success rates.
The Defender’s modular architecture allows rapid configuration for a wide range of tasks. Components like cameras, sensors, and manipulators can be easily swapped or upgraded, reducing downtime and expanding capability across multiple missions.
With the option for long-range fibre optic tethers and on-board battery power, the Defender can access hard-to-reach sites without relying on complex surface power setups—unlocking operational flexibility wherever the work takes you.
The Defender pairs robust construction with a modular design to deliver high-performance results in demanding underwater environments. Its full HD camera, integrated navigation sensors, and seven thrusters ensure precise control, clear visuals, and reliable data capture across a wide range of subsea tasks.
