The Critical Infrastructure Airspace Defense Act would: Give critical infrastructure sites the legal authority to take down unauthorized drones. Establish a grant program for critical infrastructure sites to purchase, install, and operate approved technology.
Give critical infrastructure sites legal authority to take down unauthorized drones and establish a grant program to help them buy, install, and operate approved counter-drone technology.
Occurrences
To grant authority to use counter-unmanned aircraft system technologies to private owners of critical infrastructure facilities, and for other purposes.
Evidence
GovInfo shows S. 4380 was introduced in the Senate on April 22, 2026 and referred to the Senate Homeland Security and Governmental Affairs Committee. The bill is titled the Critical Infrastructure Airspace Defense Act and is aimed at counter-UAS authority for critical infrastructure.
Cotton’s release says his bill would let critical-infrastructure sites take down unauthorized drones and create a grant program to buy, install, and operate approved counter-drone technology.
Assessments
Tom Cotton introduced S. 4380 and publicly described it as matching the promise, but the evidence shows only a Senate introduction and committee referral, not enactment or implementation. That is a serious legislative attempt, but the promised outcome was not delivered.
