T-AO 212, a future John Lewis-class fleet replenishment oiler, will be named USNS Ruth Bader Ginsburg.
The previous ships in the class are the lead ship John Lewis, Harvey Milk, Earl Warren, John F. Kennedy, Lucy Stone, Sojourner Truth and Thurgood Marshall.
Twelve additional ships of this class are planned but have not yet been named. The common naming theme for this class are civil rights activists and leaders.
Ships with the prefix USNS are not commissioned warships and are generally manned by civilian crews, except in wartime or when the ship must enter an active warzone.
