United States lightship Chesapeake (LV-116/WAL-538/WLV-538) is owned by the National Park Service and on a 25-year loan to Baltimore City, and is operated by Historic Ships in Baltimore, Maryland. Since 1820, several lightships have served at the Chesapeake lightship station and have been called Chesapeake. It was common for a lightship to be reassigned from one Lightship Station to another and thus "renamed" and identified by its new station name. Even though the "name" changed during a Lightship's service life, the hull number never changed.
