USS Cassin Young (DD-793)

Moored in the Charlestown Navy Yard opposite USS Constitution, USS Cassin Young (DD-793) presents a rare surviving example of a Fletcher-class destroyer preserved in largely authentic configuration. Launched in 1943 and commissioned at the end of that year, the ship represents the mass-produced, hard-worked surface combatants that underpinned U.S. naval operations in the Pacific. Cassin Young joined the Fast Carrier Task Force and screened carriers through major 1944–45 operations, including strikes connected to Saipan, Tinian, Guam, and the wider campaigns culminating in Leyte Gulf and Okinawa. Later reactivated during the Korean War era and in commission until 1960, the destroyer’s long career charts the transition from World War II to Cold War fleet requirements. Designated a National Historic Landmark in 1986 and one of only a handful of Fletcher-class ships still afloat, it now functions as a museum vessel within Boston National Historical Park. The setting within an historic navy yard underscores the ship’s significance as an artifact of industrial shipbuilding, radar-directed gunnery, and late-war anti-air and picket tactics rather than a static monument.
