USS Constitution - 'Old Ironsides' still a commissioned ship

USS Constitution, launched in 1797 and berthed in the Charlestown Navy Yard, is the world's oldest commissioned warship still afloat and in active U.S. Navy status. Nicknamed 'Old Ironsides' after her victories in the War of 1812, the ship is maintained by the U.S. Navy and interpreted through tours and the nearby USS Constitution Museum. The vessel's preservation and ceremonial commissioning status are well-documented aspects of Boston's maritime heritage. The ship and museum are located within the Boston National Historical Park at the Charlestown Navy Yard.
