US HB6846

Requires the Secretary of Homeland Security to submit annual terrorism threat assessments to Congress for seven years (beginning within 270 days of enactment) on the malicious use of unmanned aircraft systems (drones) by foreign adversaries and terrorist organizations

Assessments must analyze drone tactics, technologies, and trends used by adversaries including surveillance capabilities, swarm attacks, chemical/biological payload delivery, and emerging technologies like AI-enabled autonomous systems and jamming-resistant designs

Mandates evaluation of risks that foreign drone tactics could be replicated by domestic violent extremists or used to compromise border security, ports, transportation systems, and critical infrastructure

Requires DHS to develop training modules and exercises for federal, state, local, tribal, and territorial law enforcement to recognize and respond to malicious drone use, incorporating lessons from global conflicts

Assessments must be submitted in classified form with an unclassified public summary, followed by a classified congressional briefing within seven days; DHS must consult with the Department of Defense, Office of the Director of National Intelligence, and private sector counter-drone experts
