The Senate Armed Services Committee voted this week to advance legislation that would rename the Department of Defense back to the Department of War, a move that brings President Donald Trump's push to restore the original title one step closer to becoming law. The provision is embedded in the committee's version of the fiscal year 2027 National Defense Authorization Act, Military Times reported.
The vote follows a similar action by the House Armed Services Committee, which approved the name change roughly a week earlier and advanced the amendment to the Senate. Both chambers are now moving in the same direction on a proposal that supporters say would project American strength and send a clear signal to adversaries abroad.
Democrats objected. They called the renaming a vanity project and questioned the price tag. But the committee advanced the measure anyway, and Defense Secretary Pete Hegseth made clear where the administration stands.
A name older than the Constitution
The War Department was created in 1789, predating most of the federal government Americans know today. It carried that name for more than 150 years, through the Civil War, two World Wars, and every conflict in between, until President Harry Truman recommended the change to "Department of Defense" in 1947.
Trump moved to reverse that decision in September 2025, issuing an executive order declaring the return to Department of War terminology. Since then, Pentagon and federal government officials have used "Department of War" and "Secretary of War" as secondary titles. But the titles have not yet been legally established by Congress, which is why the NDAA provision matters.
Hegseth praised the House vote on social media, posting on X:
"The Department of War will officially be restored soon."
That confidence now looks well-founded. With both the House and Senate armed services committees backing the change, the legislative path is clearing.
Democrats push back on cost and symbolism
Sen. Tim Kaine, D-Va., voted against advancing the bill and issued a statement Thursday explaining his opposition. Kaine framed the name change as a distraction from what he characterized as broader foreign policy failures.
"Rather than taking steps to end this deeply unpopular war, this bill rebrands the Department of Defense as the Department of War, a juvenile move that sadly describes the reality of a President who has abandoned meaningful diplomacy in favor of starting doubtful wars in multiple locations and threatening even more."
Kaine also criticized additional funding in the bill for what he called the "illegal and foolish" war in the Middle East. His objections blend policy disagreement with rhetorical opposition to the name itself, a combination that may resonate with his base but does little to address the historical argument for the original title.
Ranking Member Jeff Merkley, D-Ore., took a different tack, zeroing in on cost. Merkley was among the lawmakers who requested a Congressional Budget Office analysis of the renaming effort. That analysis, released in January, found the rebrand could cost taxpayers between $10 million and $125 million.
Merkley seized on the high end of that range:
"Instead of prioritizing bringing down the cost of groceries or health care, Trump and his cronies are focused on vanity projects like renaming the Department of Defense to the Department of War, potentially costing American taxpayers upwards of $125 million."
He added:
"This move is performative government at its worst and does nothing to advance national security or help service members and their families."
The cost question, and what it leaves out
The CBO's $10 million to $125 million range is wide enough to drive a tank through. Merkley cites only the ceiling. Supporters could just as easily cite the floor. Neither side has offered a detailed breakdown of what drives the estimate, whether it covers signage, letterhead, IT systems, legal documents, or some combination.
For context, the Department of Defense operates on a budget measured in hundreds of billions of dollars annually. Even the high-end CBO estimate represents a fraction of a fraction of that total. Whether $125 million is a meaningful expenditure or a rounding error depends on what you think the name is worth, and what message it sends.
The federal government routinely spends far more on initiatives with less historical grounding. The War Department name carried the nation through every major conflict from the founding era through World War II. Restoring it is not an invention. It is a return. Concerns about infrastructure and preparedness spending are legitimate across the board, but they cut in every direction, not just against proposals Democrats happen to dislike.
What comes next
The Senate has yet to release its full version of the NDAA bill. The committee vote advances the provision, but floor debate, amendments, and a conference process with the House still lie ahead. The exact vote count from the committee has not been disclosed publicly.
Still, the trajectory is clear. The House committee approved the change. The Senate committee followed. The executive branch has already adopted the terminology by order. The remaining question is whether Congress will formalize what the administration has already put into practice.
Democrats have made their objections known. Kaine calls it juvenile. Merkley calls it performative. But neither has offered a compelling argument for why a name that served the republic for 158 years is somehow unfit for the 21st century.
The War Department built the military that won American independence, preserved the Union, and defeated fascism. If Democrats want to argue that "Defense" better captures the mission of an institution currently engaged in active operations across multiple theaters, they are welcome to try. The history is not on their side.
Names matter. They shape how institutions see themselves and how adversaries see them. A department named for war tends to prepare for it. One named for defense can drift toward something softer. The Senate committee, at least, seems to understand the difference.
