Prohibition on procurement and use of insecure uncrewed aircraft systems; report. Prohibits, beginning on July 1, 2025, any public body from purchasing, leasing, or otherwise procuring an insecure uncrewed aircraft system (UAS), as that term is defined in the bill. The bill further prohibits, beginning on July 1, 2029, any public body from using, whether directly or through work with or on behalf of another public body, an insecure UAS. The bill directs the Virginia Information Technologies Agency (VITA) to establish cybersecurity standards for the certification of secure UAS and maintain a list of approved UAS manufacturers and models on its website. The bill also requires the Joint Commission on Technology and Science, in collaboration with stakeholders, to review cybersecurity standards and make recommendations every two years to ensure alignment with emerging UAS technologies, evolving cybersecurity threats, the operational and safety needs of public bodies, and public safety priorities within the Commonwealth. Finally, the bill establishes the Uncrewed Aircraft Replacement Grant Program, to be administered by the Department of Criminal Justice Services, to award grants to aid public bodies with the transition from insecure UAS to secure UAS.
