Critical Infrastructure Airspace Defense Act

The Critical Infrastructure Airspace Defense Act grants owners and operators of high-risk facilities, such as power plants and substations, the legal authority to detect, track, and neutralize unauthorized drones threatening their safety. To use this power, personnel must complete a federally mandated training and certification program that ensures they follow specific operational standards and coordinate with aviation authorities. The legislation also provides $250 million in funding through 2031 to help these facilities purchase and install approved drone countermeasures while offering liability protection for authorized actions taken in good faith.
