The "Department of War Restoration Act of 2025" aims to fundamentally alter the nomenclature of the United States' primary military department. Its central provision is the redesignation of the Department of Defense as the Department of War , reflecting a proposed shift in its official identity. Furthermore, the bill stipulates that the head of this newly named department will be known as the Secretary of War , replacing the current title of Secretary of Defense. To ensure a seamless transition, the legislation mandates that all existing laws, rules, regulations, and official documents referencing the Department of Defense or Secretary of Defense will automatically be considered as referring to the Department of War and Secretary of War, respectively, upon the act's enactment.
