The Pentagon asked Congress to formally rename the Department of Defense as the “Department of War,” estimating the change would cost about $52.5 million.
That estimate was lower than a January projection from the Congressional Budget Office, which said the rebrand could cost as much as $125 million if adopted “broadly and rapidly.”
In a legislative proposal released this month, the department said the new name “serves as a fundamental reminder of the importance and reverence of our core mission, to fight and win wars. It serves as a strategic objective in which to measure and prioritize all activities.”
President Donald Trump signed an executive order in September establishing “Department of War” as a secondary title for the Department of Defense. Congress must approve any permanent renaming of an executive department, and it has not done so.
Trump said restoring the department’s original name, which was used until two years after World War II, better reflects current conditions.
“The name ‘Department of War’ conveys a stronger message of readiness and resolved compared to ‘Department of Defense,’ which emphasizes only defensive capabilities,” the executive order said. “Restoring the name ‘Department of War’ will sharpen the focus of this Department on our national interest and signal to adversaries America’s readiness to wage war to secure its interests.”
The Pentagon said the estimated cost included $44.6 million for defense agencies and field activities, $3.5 million for the military departments, $3 million for Defense Secretary Pete Hegseth’s office and Washington Headquarters Services, and $400,000 for the Joint Staff, combatant commands, and National Guard Bureau.
Hegseth and Gen. Dan Caine, chairman of the Joint Chiefs of Staff, will testify before the Senate Armed Services Committee on Thursday on the Pentagon’s fiscal 2027 budget request.
