Maintained and staffed by National Park Service staff and volunteers, Cassin Young is an example of the type of ship built, repaired, and modernized in the Charlestown Navy Yard. Although built in California, fourteen Fletcher-class destroyers just like her were produced at this yard. Cassin Young also provides a more modern contrast to USS Constitution and is a memorial to the destroyer and the ships they served on. She has been open to the public since 1981 and is basically restored to her late-1950s appearance.
