The Royal Navy is testing a state-of-the-art underwater robot capable of identifying and neutralising undersea threats, including unexploded ordnance and sabotage devices placed near vital infrastructure such as pipelines and seabed cables, the Ministry of Defence has confirmed.
The technology, developed under a Royal Navy-funded programme and trialled by the Defence Science and Technology Laboratory (Dstl), marks a major leap forward in the UK’s seabed warfare capability, amid rising global concern over undersea security.
Neutralising Threats Where Divers Cannot Go
The robot, a commercially available remotely operated vehicle (ROV) enhanced with advanced tools and sensors, was tested across multiple locations including Portland Harbour, South Wales, Horsea Island, and even in Norwegian waters.
Dstl says the platform can remotely place explosive charges and safely dispose of underwater hazards, including legacy mines and sabotage devices, all while keeping Navy personnel at a safe distance.
“This unique capability… gives operators real-time ability to deal with these underwater hazards in a safe, effective and efficient way,” said a Dstl explosives engineer identified only as John.
The robot operates at depths beyond the reach of human divers, transmitting live video and sonar imagery to shore or ship-based teams. It can be launched from either a vessel or the shoreline, and remain submerged for extended periods.
Reusable, British-Made, and Combat-Ready
Unlike many military drones, the robot is designed to be reusable, significantly lowering operational costs and allowing for rapid redeployment when multiple threats are identified.
The system is being delivered in collaboration with UK industry, involving key defence technology firms including Alford Technologies, Atlantas Marine, Sonardyne, and ECS Special Projects, supporting British jobs and innovation in the process.
The MoD said the technology provides both tactical flexibility and strategic deterrence, with Navy personnel already developing new doctrine and training around its operational use.
Strategic Context: Protecting the Seabed
The trials come amid heightened geopolitical attention to the vulnerability of critical undersea infrastructure, especially following incidents such as the Nord Stream pipeline explosions and increased submarine activity in contested waters.
Officials said the robot could play a vital role in safeguarding energy, data, and military cables, areas increasingly seen as frontlines in a future conflict.
“This is a cutting-edge capability that keeps our Armed Forces safer while delivering value for the taxpayer,” a Ministry of Defence spokesperson said.
