The Pentagon has formally asked Congress to swap its legal name from the Department of Defense to the Department of War, and the tab for the effort has already climbed to roughly $50 million. The request follows a September executive order from President Donald Trump that authorized “Department of War” as a secondary title, with Defense Secretary Pete Hegseth pushing the new branding inside the building. The move is setting up a partisan clash over whether the change should be locked into law and who is going to pay for the makeover.
OGC posts legislative proposal
According to Bloomberg, the Pentagon’s Office of General Counsel has posted a formal legislative proposal that asks Congress to amend the statute that created the department so the new name would be official. The outlet notes that the filing arrives after the department already started rolling out the branding under guidance from the secretary following last fall’s executive order.
How much the department says it has spent
In its proposal, the Defense Department tells lawmakers it has moved quickly on the rollout and that initial implementation costs in fiscal 2026 will land in the tens of millions. Breaking Defense reports the department cited about $50 to $52 million just to get the transition started, with much of that money concentrated in defense agencies and field activities as they replace signage, templates and other branded items.
CBO: bigger range, bigger risks
The Congressional Budget Office is warning that the ultimate price tag could swing far higher depending on how aggressively the government carries out the swap. CNN summarized the CBO’s estimate that a modest, phased-in change might cost roughly $10 million, while a broader, faster replacement effort across the department could approach $125 million. A statutory renaming that required immediate updates across the federal government, the office warned, could run into the “hundreds of millions.”
Legal implications
Under the law, an executive order cannot rewrite statute. The White House directive that authorized Department of War as a secondary title explicitly left statutory references untouched and instructed the secretary to send recommendations to the president and Congress. The full text of Executive Order 14347 is available on the White House site and makes clear that only Congress can change the department’s legal name.
Why this matters in Congress
The Pentagon’s formal request is expected to land squarely in the middle of negotiations over the fiscal 2027 defense bill, and, as Breaking Defense reports, it is likely to spark a sharp partisan dispute over both costs and symbolism. Lawmakers will have to decide whether to write language that codifies the new name, resist the change outright, or tack on riders that limit how far and how fast the rebranding can go.
Where the money goes
On paper, the CBO and department estimates point to the same general buckets of spending: new signage, updated seals and plaques, refreshed websites and digital domains, redesigned stationery and identity badges, and reprinted training and legal materials. CNN noted that the CBO relied in part on a Pentagon spending snapshot showing millions already poured into flags, plaques and revised badges in short order.
What happens next
Ultimately, it will be up to Congress to decide whether Department of War becomes the building’s legal name or stays a kind of internal marketing campaign. For now, the department is tallying implementation costs and asking lawmakers to decide whether statute should catch up with the signage, a choice that will surface quickly in upcoming budget and authorization debates on Capitol Hill.
