The Pentagon has formally requested congressional approval to rename the "Department of Defense" to the "Department of War," estimating the change will cost approximately $52 million. The proposal, part of a legislative package, seeks to amend all references in federal law, including renaming the Secretary of Defense to the Secretary of War. The department has already begun implementing changes, such as updating its website and social media accounts, following President Donald Trump's September 2025 executive order and Secretary Pete Hegseth's October 2025 guidance. The Pentagon claims the rebranding will have no significant impact on the FY 2027 budget, as most costs will be absorbed in the current fiscal year.
Cost Breakdown and Implementation
The estimated $52 million includes $44.6 million for defense agencies and field activities, $3.5 million for military departments, $3 million for the Pentagon's office and Washington Headquarters Services, and $400,000 for the Joint Staff, Combatant Commands, and National Guard Bureau. The change would require around 7,600 amendments to federal law. The Congressional Budget Office previously estimated costs could range from $10 million to $125 million, depending on implementation speed.
Rationale and Reactions
The Pentagon justifies the change as a "fundamental reminder" of its core mission to "fight and win wars." Critics, including some lawmakers, have questioned the necessity and cost of the rebranding, while supporters argue it aligns with the department's historical roots and strategic priorities. The proposal has sparked debate over defense spending priorities and the symbolic weight of the name change.
