Approval by the House Armed Services Committee adds a new flashpoint to an already contentious defense spending debate.
TrumpRepublicans on the House Armed Services Committee have endorsed a proposal to formally rename the Department of Defense as the “Department of War,” advancing one of President Donald Trump’s most controversial government rebranding efforts and setting up a new partisan battle over the annual defense policy bill.
The proposal was approved late Thursday as part of the fiscal year 2027 National Defense Authorization Act (NDAA), a sweeping defense package that authorizes approximately $1.15 trillion in military programs and policies. The amendment, introduced by Representative Ronny Jackson of Texas, passed on a narrow party-line vote of 29-27 during a marathon committee session.
If ultimately enacted, the measure would formally change the legal name of the Department of Defense, codifying a rebranding effort that Trump first launched through executive action in 2025. Under that order, federal agencies were permitted to use “Department of War” and “Secretary of War” as secondary titles in official communications, although the department’s statutory name remained unchanged because only Congress has the authority to rename a federal department.
Supporters argue that the historic name better reflects the military’s primary mission. Jackson told lawmakers that restoring the title would send a message of strength to potential adversaries and reinforce a “warrior ethos” within the armed forces. Defense Secretary Pete Hegseth has also embraced the terminology, frequently referring to himself as “Secretary of War” since Trump’s executive order was issued.
The Department of War was one of the original executive departments established in the early years of the United States. Following World War II and the passage of the National Security Act, the federal government reorganized the military structure, eventually adopting the name “Department of Defense” in 1949 to reflect a broader national security mission beyond wartime operations.
Democrats strongly opposed the proposal, describing it as an expensive symbolic gesture that does little to address military readiness or emerging security threats. Critics argue that the renaming could require widespread updates to official documents, regulations, signage, websites and branding across the federal government. Budget analysts have estimated the cost could reach as much as $125 million, though some outside estimates have suggested an even higher price tag depending on implementation.
The debate over the Pentagon’s name comes as lawmakers are already divided over a range of national security issues, including military spending levels, oversight of overseas operations, personnel policies and the future direction of US defense strategy. While the broader NDAA advanced out of committee with bipartisan support, the renaming amendment injected a new ideological dispute into legislation that has historically been one of Congress’s most reliable bipartisan achievements.
The measure now moves to the full House of Representatives, where lawmakers will have another opportunity to amend the bill. Even if it survives that process, its future remains uncertain in the Senate, where bipartisan support would likely be required for the proposal to become law. Several senators from both parties have already signaled skepticism toward symbolic changes that could complicate negotiations on the broader defense package.
For Trump and his allies, the proposal represents an effort to reshape the language and identity of the US military establishment. For opponents, it is a costly political statement that risks distracting from pressing defense challenges. As the annual defense bill heads toward floor debate, the battle over the Pentagon’s name is likely to become one of the most closely watched—and politically charged—issues in the broader national security discussion.
