The Navy is set to name a ship after the gay rights icon and San Francisco politician Harvey Milk, according to a Congressional notification obtained by USNI News.

The July 14, 2016 notification, signed by Secretary of the Navy Ray Mabus, indicated he intended to name a planned Military Sealift Command fleet oiler USNS Harvey Milk (T-AO-206). The ship would be the second of the John Lewis-class oilers being built by General Dynamics NASSCO in San Diego, Calif.

The Secretary of the Navy’s office is deferring releasing additional information until the naming announcement, a Navy official told USNI News on Thursday.

Mabus has said the John Lewis-class – named after civil rights activist and congressman Rep. John Lewis (D-Ga.) – would be named after civil rights leaders.

Other names in the class include former Supreme Court Chief Justice Earl Warren whose court ruled to desegregate U.S. schools, former Attorney General Robert F. Kennedy, women’s right activist Lucy Stone and abolitionist and women’s rights activist Sojourner Truth.

Mabus has also named ships in the past for other civil rights icons, including the Lewis and Clark-class dry cargo ships USNS Medgar Evers (T-AKE-13) and USNS Cesar Chavez (T-AKE-14).

Milk came from a Navy family and commissioned in the service in 1951. He served as a diving officer in San Diego during the Korean War on the submarine rescue ship Kittiwake until 1955. Milk was honorably discharged from the service as a lieutenant junior grade.

Following his service, Milk was elected to the San Francisco board of supervisors and was the first openly gay California politician to be elected to office. He was killed in office in 1978. When Milk was shot he was wearing his U.S. Navy diver’s belt buckle.

Over the last several years, there have been pushes from California politicians to have a ship named for Milk since the 2011 repeal of the Department of Defense’s “Don’t Ask, Don’t Tell.” policy.

Naming a ship after Milk, “will further send a green light to all the brave men and women who serve our nation that honesty, acceptance and authenticity are held up among the highest ideals of our military,” said Milk’s nephew Stuart Milk in a statement to San Diego LGBT Weekly in 2012.
