DEFEND Act

The DEFEND Act requires the Department of Homeland Security to produce annual assessments (starting 270 days after enactment) on terrorism threats posed by foreign adversaries and terrorist groups using drones. These assessments must analyze how adversaries acquire, deploy, and technologically enhance drones for surveillance, attacks on infrastructure, or mass casualties - including emerging tactics like AI-driven swarms or chemical payloads - and include lessons from global conflicts. The reports, submitted to Congress and accompanied by classified briefings, also mandate DHS to develop training for law enforcement on recognizing and responding to drone threats. This bill directly affects DHS operations, congressional oversight, and state/local law enforcement preparedness, without creating new regulations or funding.
