Executive order seeks to revive the institution’s historic designation
President Donald Trump announced that he will sign an executive order on Friday to change the name of the Department of Defense, restoring its historical title: Department of War. The measure would reinstate a designation used from the nation’s early years until after World War II, when Congress approved the current name in 1949 as part of reforms led by President Harry Truman.
According to official information, the new title would serve as a secondary designation and apply to both the institution and its leadership. This would allow current Secretary of Defense Pete Hegseth to adopt the title Secretary of War.
Scope and potential implications
The proposal raises questions about legal requirements, since the Department of Defense name was established by an act of Congress. Trump acknowledged the uncertainty but expressed confidence that lawmakers would support the change if necessary.
Financial and logistical implications are also expected. Updating seals, signage, documents and official titles could entail significant costs. As a reference, the U.S. Army reported in 2023 that renaming only nine military bases cost taxpayers $39 million.
Historical background
The Department of War has deep roots in American history. From the nation’s founding, it oversaw the Army and Navy under that name. The transition to “Department of Defense” in the mid-20th century was intended to reflect a broader mission of coordination and unity among military branches.
If enacted, Trump’s order would represent a symbolic shift in how the U.S. government refers to its primary military institution.
