The Monroe Doctrine was penned at Oak Hill, and subsequently delivered at an 1823 Congressional address which asserted that the Western Hemisphere was never to be colonized again. This doctrine is the inspiration for the Ship’s Motto: Nations’ Protector. Oak Hill is the second ship to honor the residence.^[1]

Oak Hill is currently homeported at Little Creek Amphibious Base, Virginia Beach, Virginia, and is assigned to Amphibious Squadron 8
