This bill requires the Secretary of Defense to create department-wide guidelines for identifying and removing artificial intelligence products from covered companies out of all Defense Department systems and devices. The Secretary must issue this guidance within 30 days after the bill becomes law, establishing clear procedures for both identifying which AI companies are "covered" under the policy and for excluding or removing their AI products from military equipment and software. The bill amends existing defense authorization law and includes a 90-day implementation timeline for the exclusion requirements to take effect. The legislation directly affects the Department of Defense and its use of AI technology, though the specific definition of which companies are "covered" would be determined by the Secretary through the guidance process. No specific funding amount is mentioned in the bill text, as the costs would fall within existing Defense Department budgets.
