The UK Defence Science and Technology Laboratory (Dstl) has tested an underwater robot designed to enhance the Royal Navy’s maritime security capabilities.
The Dstl and industry partners modified a commercially available remotely operated vehicle (ROV) to address potential sabotage activities targeting undersea cables and pipelines, as well as to mitigate risks associated with unexploded ordnance.

Dstl has integrated various systems into the ROV to facilitate the detection of unexploded munitions.
It has also equipped the robot with the capacity to remotely deploy explosive charges, thereby allowing for the secure neutralisation of these underwater threats.
Trials for this technology have been conducted at Horsea Island in Portsmouth, Portland Harbour, South Wales, and Norway.
The Ministry of Defence (MoD) and Dstl believe this advancement not only promises increased protection for naval assets but also reduces the danger faced by divers traditionally tasked with such operations.

Dstl explosives engineer John said: “This technology would be a valuable toolset for keeping our Armed Forces safe whilst providing the public with value for money.
“This unique capability with its sensors, tools and cameras will give operators a real time ability to deal with these underwater hazards in a safe, effective and efficient way.”
The ROV can operate at depths beyond the reach of divers and can remain submerged for extended periods.
It will work alongside other robots to scan the seabed for hazards and address them once identified.
Capable of being launched from ships or shorelines, the robot is operated remotely, providing video and sonar feedback to operators who can then safely manage underwater hazards.
The ROV’s reusability offers economic benefits and supports specialist jobs in the industry.
The MoD recently disclosed plans to invest £5bn in the development and procurement of uncrewed autonomous systems and laser weapon systems over the course of the current Parliament, which spans the next five years.
The funding is set to be divided, with £4bn earmarked for autonomous systems and £1bn dedicated to laser weapon technology.
This financial commitment follows recommendations from the Strategic Defence Review (SDR), released on 2 June 2025, which advocates for a transformation of the UK armed forces through increased reliance on autonomous capabilities.
