Prevents the Secretary of the Navy from renaming any naval vessel that, on the date this Act becomes law, is named for Cesar Chavez, Medgar Evers, Ruth Bader Ginsburg, Dolores Huerta, Thurgood Marshall, Harvey Milk, Lucy Stone, or Harriet Tubman. The prohibition applies despite the general renaming authority in federal law, making these specific ship names permanently protected from change while the law remains in effect.
