This legislation, titled the Department of Energy Drone Defense Act , establishes specific exemptions for the Secretary of Energy concerning unmanned aircraft systems (UAS) from covered foreign entities. It amends the National Defense Authorization Act for Fiscal Year 2024 to allow the Secretary to procure and operate these UAS, overriding existing prohibitions. The bill further exempts the Secretary of Energy from restrictions on using federal funds for the acquisition and deployment of such UAS. Moreover, it grants the Department of Energy an accounting exception , providing flexibility for its drone-related operations. These provisions collectively enable the Department of Energy to utilize certain foreign-sourced drones for its missions.
