The Warrior Right to Repair Act of 2025 aims to enhance the Department of Defense's (DoD) ability to maintain and repair its procured goods. It mandates that agencies cannot enter into new procurement contracts unless the contractor agrees to provide the DoD with fair and reasonable access to all repair materials, including parts, tools, and information, used by the manufacturer or their authorized repair providers. This ensures the DoD can effectively diagnose, maintain, or repair its equipment. The bill defines "fair and reasonable access" to include terms and conditions allowing the DoD to provide these materials to authorized contractors, at prices and conditions equivalent to those offered to other authorized repair providers. For existing programs, the head of an agency may waive this requirement if a justification, based on an independent technical risk assessment, is submitted to congressional defense committees. Furthermore, the Secretary of Defense is directed to review and identify necessary contract modifications to remove intellectual property constraints that currently limit the DoD's access to repair materials and its maintenance capabilities. The Comptroller General is also required to report on the implementation and compliance with these new requirements within one year of enactment.
