Block Nuclear Launch by Autonomous Artificial Intelligence Act of 2023

This bill prohibits the use of federal funds to develop or deploy any autonomous weapons system that lacks meaningful human control for nuclear weapons decisions. It directly affects defense programs receiving federal funding by banning the use of taxpayer money for AI systems that could select targets or launch nuclear weapons without human authorization. The key provision (Section 4) states that no funds may be spent on such systems for nuclear launches or target selection, requiring human control over target selection, timing, location, and execution. The bill aligns with existing U.S. policy requiring a human "in the loop" for nuclear decisions, as stated in the 2022 Nuclear Posture Review and the 2023 Political Declaration on AI.
