The order immediately changes how the department and its leaders may present themselves, but a permanent renaming would require further legal and executive action.

What the order does

  • Authorizes “Department of War,” “Secretary of War,” and corresponding titles for official communications, ceremonies, and other non-statutory uses.
  • Directs all executive departments and agencies to recognize the secondary titles when they do not conflict with legal, statutory, or international obligations.
  • Keeps statutory references to the Department of Defense and its officials legally controlling.
  • Requires notification to Congress within 30 days about offices, agencies, components, or commands adopting the secondary designation.
  • Requires recommendations within 60 days on legislation and executive actions needed to make the renaming permanent.

Who it affects

  • Department of Defense officials, components, and commands using the secondary titles.
  • Federal departments and agencies handling communications that use the secondary titles.
  • Congress, which will receive notice of secondary-name adoption and may be asked to approve a permanent change.
