Workers remove sign lettering Sept. 5 at the PentagonΒ in Washington after President Donald Trump signed an executive order aiming to rename the Department of Defense the Department of War.

WASHINGTON β€” Renaming the Department of Defense the Department of War could cost U.S. taxpayers as much as $125 million, depending on how broadly and quickly the change is made, according to a new analysis by the Congressional Budget Office.

President Donald Trump signed an executive order in September that authorized the Department of War as a secondary title for the Pentagon. At the time, Trump said the switch was intended to signal to the world that the U.S. was a force to be reckoned with, and the Republican leader complained that the Department of Defense name was "woke."

The order came as the military began its campaign of deadly airstrikes against alleged drug-carrying boats in South America. Since then, a military operation captured then-Venezuelan President NicolΓ‘s Maduro and the Trump administration threatened military action in places from Iran to Greenland.

Congress would have to formally approve a new name for the department. Republican lawmakers, including Sens. Mike Lee, Rick Scott and Marsha Blackburn, introduced legislation to make the name change official shortly after Trump signed the executive order, but the measure did not progress.Β 

Nevertheless, Defense Secretary Pete Hegseth embraced the rebrand and proceeded to use it on several signs after Trump's order.

He had employees remove the large gold letters that spelled "Secretary of Defense" outside his office and replaced the sign on his door to read "Secretary of War." The Pentagon's website also went from "defense.gov" to "war.gov" the same day the executive order was signed.

At the time, Pentagon officials said they could not offer a cost estimate for the name change because they expected costs to fluctuate. They promised a clearer estimate later.

The new CBO report says costs would be at least a few million dollars if the name change was phased in with minimal implementation, but could reach $125 million if it was implemented broadly and rapidly throughout the department.

The assessment said it would cost about $10 million for a "modest implementation" of the executive order if the name change happened within the agency, and such a cost would most likely be absorbed within the Pentagon's existing budgets.

"A statutory renaming could cost hundreds of millions of dollars," depending on how Congress and the Defense Department choose to to do it, the report says.

The Pentagon has more than 6.5 million square feet of office space, and many of the signs, logos and seals remain unchanged. It is not clear if the push to alter the Defense Department's name was carried out at the numerous U.S. military facilities around the world.

The order tasked Hegseth with recommending actions required to change the name permanently. Pentagon officials did not answer questions about what, if any, recommendations were made.

The new analysis was requested by Senate Democratic leader Chuck Schumer, D-N.Y., and Sen. Jeff Merkley, D-Ore.

Lawmakers established the CBO more than 50 years ago to provide impartial analysis to support the budget process.
