Defense Secretary Pete Hegseth has ordered the Navy to strike the name of gay rights activist Harvey Milk from one of its ships, orchestrating the change as Pride month celebrations take place.

A defense official said the timing of the decision was intentional.

The order was first reported by Military.com and confirmed by ABC News.

The USNS Harvey Milk is one of several ships named after prominent civil rights leaders and activists. A new name has not been announced.

Milk was one of the first openly gay men elected to public office in the United States after winning a seat on the San Francisco Board of Supervisors in 1977. He was assassinated a year later.

Before his death, Milk was credited with encouraging his friend and artist Gilbert Baker, a U.S. Army veteran to create the Pride flag. Milk was played by Sean Penn in the 2008 biographical film "Milk."

Hegseth and Navy Secretary John Phelan did not immediately respond to requests for comment from ABC News.
