Throughout its history, the yard has been associated with names like Washington, Jefferson, Lincoln, and Kennedy. Kings and queens have visited the yard; its waterfront has seen many historic moments; and some of our Navy's most senior and most notable officers have called it home. Such legendary ships as USS Constitution and USS Constellation sailed from its piers, and the 14-inch and 16-inch guns that armed our Navy's battleships during Word Wars I and II were built in its factories.
