The real showstopper at this family-friendly complex, just across the Cooper River from Downtown Charleston, is the USS Yorktown, one of America’s most famous navy ships. This aircraft carrier was commissioned in 1943 and named after the ship sunk at the Battle of Midway 1 year earlier. It served in World War II and off Vietnam between 1965 to 1968, finally being decommissioned in 1970. Though Yorktown is the main attraction, you can also peruse the Shipyard Museum, explore the USS Clamagore, a 1945 submarine, and the USS Laffey, a destroyer commissioned in 1944, serving in World War II and Korea.
