Project Halo Shield
Coverage from GOV.UK, The Defense News, and others

Project Halo Shield is a British Army initiative for detecting and tracking drones around military facilities without initially using active measures to disable them.
Deployed at Warminster Garrison, it combines Dedrone’s radio-frequency sensors and command-and-control software with Quell’s SkySpyke optical detection system. During an initial 17-day monitoring period, the system recorded 29 drone position alerts at distances of up to five kilometres. Beyond surveillance, Halo Shield supports Army training and provides a foundation for possible expansion with radar and acoustic sensors across additional UK garrisons.
