Defense Secretary Pete Hegseth has ordered the Navy to rename the USNS Harvey Milk, a highly rare move that will strip the ship of the moniker of a slain gay rights activist who served as a sailor during the Korean War.

U.S. officials say Navy Secretary John Phelan put together a small team to rename the replenishment oiler and that a new name is expected this month. The officials, who spoke on condition of anonymity to discuss internal deliberations, said the next name had not yet been chosen.

The change was laid out in an internal memo that officials said defended the action as a move to align with President Donald Trump and Hegseth’s objectives to “re-establish the warrior culture.”

It marks the latest move by Hegseth and the wider Trump administration to purge all programs, policies, books and social media mentions of references to diversity, equity and inclusion. And it comes during Pride Month — the same timing as the Pentagon’s campaign to force transgender troops out of the U.S. military.

Pentagon spokesman Sean Parnell said in a statement that Hegseth is “committed to ensuring that the names attached to all DOD installations and assets are reflective of the Commander-in-Chief’s priorities, our nation’s history, and the warrior ethos.”
