UK military sites experienced approximately 340 drone security incidents in the year leading to August 2026, a sharp rise from 250 in 2025 and 126 in 2024. While the Ministry of Defence has not attributed the flights, experts and former officials point to Russia and Iran as likely sponsors of these passive surveillance operations. In response, the UK is expanding restricted airspace to 160 additional sites and advancing the Armed Forces Bill to allow military personnel to neutralize threatening drones.
