The National Defense Authorization Act for Fiscal Year 2027 authorizes funding for military activities of the Department of Defense (DoD), military construction, and defense activities of the Department of Energy (DoE), while also setting military personnel strengths for the fiscal year. The bill is structured into four main divisions: DoD Authorizations, Military Construction Authorizations, DoE National Security Authorizations, and Funding Tables. Division A, focusing on DoD Authorizations, includes significant provisions across various areas. For procurement , it authorizes multiyear contracts for critical aircraft like the F-35, F-15EX, and E-2D Advanced Hawkeye, alongside Army Infantry Squad Vehicles and various munitions. It also places limitations on the divestment of MQ-9 aircraft and retirement of E-3 aircraft, and mandates a mobility capabilities strategic plan for the Air Force. In Research, Development, Test, and Evaluation (RDT&E) , the bill directs the development of alternative low-cost weapon systems, codifies the DoD Research Security Program, and establishes the Science, Technology, and Innovation Board. It also streamlines processes for international science and technology agreements. For Operation and Maintenance (O&M) , key provisions include authorizing sustainable aviation fuel procurement, enhancing grid resiliency, prioritizing expeditionary solid waste disposal, and addressing PFAS remediation efforts. Regarding military personnel , the bill sets end strengths for active and reserve forces and modifies officer personnel policies related to promotions and retirements. It also expands whistleblower protections and introduces new policies on diversity, equity, and inclusion, including sex-neutral occupational standards. Military justice reforms are also addressed, expanding victim access to the Court of Appeals for the Armed Forces and clarifying special trial counsel authority. Health care provisions include establishing a digital system for beneficiary assistance, expanding dental care access, and evaluating additional accrediting bodies for mental health professionals under TRICARE. It also mandates medical chaperones for sensitive examinations and establishes a pilot program for reciprocal access to DoD and VA health care facilities. The bill also requires a Joint Disease and Non-Battle Injury Surveillance and Readiness System and mandates an annual large-scale combat casualty estimation report. For acquisition policy and management , the legislation authorizes multi-year procurement for specific munitions and modifies technical data rights to support competition and sustainment. It also introduces limitations on capital distributions for defense contractors and prohibits procurement of certain materials (molybdenum, gallium, germanium) and optical fiber from non-allied foreign nations, particularly China. The bill proposes significant changes to DoD organization and management , including the establishment of an Economic Defense Unit and potentially a United States Robotic and Autonomous Systems Command. It also redesignates the Under Secretary of Defense for Personnel and Readiness as the Under Secretary of Defense for Personnel and Health Affairs and creates new Assistant Secretary positions. Division B authorizes specific military construction projects for the Army, Navy, Air Force, and Defense Agencies, both inside and outside the United States. This includes funding for family housing, energy resilience and conservation projects, and contributions to the NATO Security Investment Program. It also extends previous years' military construction authorities and modifies certain project scopes. Division C authorizes appropriations for Department of Energy National Security Programs , covering the National Nuclear Security Administration, defense environmental cleanup, and other defense activities. It also includes provisions for nuclear energy and the Defense Nuclear Facilities Safety Board. Finally, Division D outlines the specific funding tables for all authorized appropriations.
