Protecting the Border from Unmanned Aircraft Systems Act This bill requires the Department of Homeland Security (DHS) to coordinate with the Department of Justice (DOJ), the Federal Aviation Administration, the Department of State, the Department of Energy, the Office of the Director of National Intelligence, and the Department of Defense to develop a strategy for a unified posture on counter-unmanned aircraft systems capabilities and protections at certain facilities at or near a U.S. international border (generally, facilities or assets considered high-risk or a potential target and that are related to certain DHS or DOJ missions).
