The Counter-UAS Authority Extension Act aims to prolong the ability of federal agencies to safeguard critical infrastructure and assets from unmanned aircraft. Specifically, it extends the existing counter-unmanned aircraft system (C-UAS) authorities granted to the Department of Homeland Security and the Department of Justice . The bill achieves this by amending the Homeland Security Act of 2002, changing the current expiration date for these authorities from September 30, 2025, to September 30, 2028 . This extension ensures that DHS and DOJ can continue to employ necessary measures to detect, identify, and mitigate threats posed by drones to protected facilities and events.
