A bill to require the Under Secretary of Defense for Intelligence and Security to complete a threat assessment regarding unmanned aircraft systems at or near the international borders of the United States, and for other purposes.

This bill, the Border Drone Threat Assessment Act (S 1908), requires the Under Secretary of Defense for Intelligence and Security to complete a detailed threat assessment of unmanned aircraft systems (drones) near U.S. international borders within one year. The assessment must cover threats from foreign actors, current detection capabilities, drone data use, tactics employed, privacy considerations, and government countermeasures. It mandates a report to Congress within 180 days of completion, including findings on security gaps and whether additional authorities or resources are needed. The bill directly affects federal agencies like the Department of Defense, Homeland Security, and intelligence community elements responsible for border security. The goal is to inform Congress about drone-related threats and government readiness to address them along U.S. borders.
