President Donald Trump signed an executive order Friday to rebrand the Pentagon as the “Department of War,”

“I think it’s a much more appropriate name, especially in light of where the world is right now. We have the strongest military in the world,” Trump said, before signing the order.

The order authorizes the Secretary of Defense, the Department of Defense and subordinate officials to use secondary titles such as “Secretary of War,” “Department of War,” and “Deputy Secretary of War” in official correspondence, public communications, ceremonial contexts, and non-statutory documents within the executive branch, according to a fact sheet obtained by CNN. And almost immediately, officials began to implement it.

Pentagon officials changed signage outside of Defense Secretary Pete Hegseth’s office, and the department’s website got a revamp. The old site, defense.gov, is now rerouted to war.gov which displays “U.S. Department of War” at the top. DOD — the acronym for Department of Defense — is also replaced with DOW for Department of War in various headlines.

Hegseth, who joined the president in the Oval Office, said the name change is “not just about renaming, it’s about restoring.” Hegseth said the military will “go on offense, not just on defense” and, reflected in the name change, the country will “raise up warriors, not just defenders.”
