What this bill would do
The Critical Infrastructure Airspace Defense Act seeks to grant authority to private owners and operators of critical infrastructure to use counter-unmanned aircraft system technologies. This authority allows them to detect, track, and mitigate credible threats posed by unmanned aircraft systems to their facilities. To use these powers, personnel must undergo specific training and certification coordinated by the Secretary of Homeland Security. The bill also establishes a grant program to help these owners purchase and operate approved technologies. This legislation aims to close a security gap currently faced by the North American electric grid and other vital sectors. The specific authority granted under this act is set to terminate on September 30, 2031.
