This bill directs the Department of Defense to hire the National Academy of Sciences, Engineering, and Medicine to conduct an independent review of occupational health and safety conditions at facilities used for the Minuteman III intercontinental ballistic missile system. The review will examine potential health hazards faced by military personnel who work in these facilities, including exposure to asbestos, radiation, volatile chemicals, and other toxic substances, and will compare cancer rates among Minuteman III operators to other Air Force personnel. The National Academy must complete its review and submit a report to Congress within 18 months, including recommendations for improving workplace safety at current Minuteman III facilities and applying lessons learned to the newer Sentinel missile system. The bill does not specify funding amounts but requires the Defense Department to provide necessary security clearances and information access to facilitate the independent review. This legislation affects current and former Air Force personnel who have worked with the Minuteman III system as well as future operations of its replacement system.
