The U.S. Army has expanded its air campaign against drug cartels along the U.S.-Mexico border, adding detection and neutralisation of hostile drones to surveillance and counter-narcotics missions. U.S. Northern Command has linked the effort to more than 300 drones neutralised since the start of the year, with over 100 intercepted in August alone, while aircraft such as the MQ-9 Reaper, MQ-1C Gray Eagle and RQ-4 Global Hawk support wide-area monitoring and precision response.
The operation now extends beyond maritime interdiction and into persistent border airspace control, where cartel-linked unmanned aircraft have become a growing threat. The Army’s Amp-Hel high-energy laser system entered border security duty on 24 August and had neutralised 11 drones by 4 September, underscoring the shift from trial use to operational deployment. The focus on counter-UAS activity places directed-energy weapons alongside traditional ISR platforms in a live security environment, with the border functioning as an active test bed for layered air defence against low-cost drones.
