AI drones are rewriting the rules of explosive detection — and the UK is betting heavily on both
The British Army just concluded a multi-week trial in Essex that makes a strong case for what the future of bomb disposal looks like: not a person crawling toward a buried shell, but a drone hovering at a safe distance while AI does the searching.
The trial, run by the Defence Science and Technology Laboratory (Dstl) and 33 Engineer Regiment, placed dozens of replica mines and ordnance across varied terrain. Quadcopter drones equipped with optical cameras, thermal sensors, long-wave infrared, and magnetometers relayed data to Army operators, who used AI tools to locate and identify munitions without entering the blast radius. The critical advance was the AI's adaptability — models were rapidly retrained to recognise new threat types and different environments, a capability the MOD says is essential given how fast the threat landscape evolves in modern warfare.
"We are testing, adapting and demonstrating this technology so that, working closely with the end user, we can develop concepts that let our forces compete on the modern battlefield," said Dstl's technical lead on the trial.
The human story is at the center of this. "The equipment being developed by Dstl will allow EOD operators to conduct their mission faster and will remove people from the explosive hazard," said Major Mark Fetters, British Army Future Counter-Explosive Ordnance Capability lead. That phrase is the humanitarian pitch, and it is a real one. But it is also military doctrine in motion.
The UK is putting money behind it. Through the Strategic Defence Review, the government is doubling investment in autonomous platforms from £2bn to £4bn this parliament. Project GARA (Ground Area Reconnaissance and Assurance), the vehicle for developing the front-line Future Counter-Explosive Ordnance Capability, is part of that push. The stated target is a tenfold increase in lethality over the next decade using firepower, surveillance technology, autonomy, digital connectivity and data.
What the Essex trial demonstrates is the detection layer of that ambition. The question is whether the classification and response layers can keep pace.
The urgency is driven in part by Ukraine, which has become the most heavily mine-contaminated country in the world — an estimated 30% of its territory, roughly 174,000 square kilometres, strewn with anti-personnel mines, cluster submunitions, failed artillery shells, and unexploded ordnance. Ukraine's experience has demonstrated to Western militaries that drone and explosive device technology reshapes the battlefield at pace, creating an explosive ordnance problem that conventional EOD methods cannot scale to meet.
There is a trust problem embedded in this story that deserves attention. AI-powered detection systems flag anomalies — they do not yet reliably distinguish between a live shell and an inert piece of metal that happens to have ferrous properties. The drone can see, but someone still has to decide. The technology narrows the danger zone; it does not eliminate the human judgment call. The gap between "we can see it from 50 metres" and "we can clear it without a human in the loop" is where the failure modes live, and it is also where the next round of investment will be tested.
For defence ministries, the trial is a proof of concept worth watching. For defence technology companies building sensor payloads and AI classification models, it is a market signal with a defined customer and a stated procurement timeline. For EOD operators currently doing this work the hard way, it is a preview of what their successors' tools might look like — if the technology matures as projected.
The Essex trial used replica ordnance on a test range. The step from that environment to a contaminated operational theatre is significant. GARA aims to reach front-line command-funded equipment programmes over the next decade. That is a long runway, and a lot can happen between a government press release and fielded capability.
But the direction of travel is clear. AI-enabled drones are moving from surveillance to intervention — and the race to make them safe enough, fast enough, and smart enough to work beside human operators in the world's most dangerous terrain is accelerating.
