British Army tests AI drones to find mines before troops move in
The British Army has completed a multi-week trial of AI-enabled drones designed to speed mine clearing and keep explosive ordnance teams farther from danger. The exercise in Essex brought together the Army and the Defence Science and Technology Laboratory to test how uncrewed aircraft, advanced sensors and machine vision can detect, identify and geolocate hidden munitions before soldiers enter a contaminated area.
The work forms part of Project Ground Area Reconnaissance and Assurance, which supports the Army’s Future Counter-Explosive Ordnance Capability. The need is growing. Modern battlefields are littered with anti-personnel mines, anti-vehicle mines, unexploded artillery shells and cluster submunitions. Mixed minefields are especially hard to clear because they can contain metallic devices, minimum-metal designs and plastic-bodied munitions that are difficult to detect with conventional tools, particularly when they are buried or obscured.
In the latest trial, teams used quadcopter drones equipped with optical, thermal and long-wave infrared sensors, along with magnetometers and computer vision software. The drones relayed data to remote Army personnel, who used AI tools built for rapid retraining as new information becomes available. That allowed the system to search for threats, classify objects and assign coordinates before a human operator approached the site. If a new munition type or threat signature appeared on screen, operators could upload fresh imagery and data to improve the model’s recognition performance.
Officials did not disclose the technical details of the system, but said the concept fits a three-stage process: detect and classify, mark and prioritize, then neutralize. The final step could be carried out by robots, drones placing explosive charges or, only if necessary, human operators. British Army officials said the capability should improve as sensors become lighter, smaller and more power-efficient, making it easier to fit more capable payloads onto smaller uncrewed aerial systems. The result could reshape battlefield clearance by cutting search times, improving threat mapping and reducing the number of personnel exposed to explosive hazards.
