USS Constitution

 The USS Constitution, also known as Old Ironsides, is a wooden-hulled, three-masted heavy frigate of the United States Navy named by President George Washington. She is the world's oldest commissioned naval vessel still afloat. The ship earned its nickname during the War of 1812 against Great Britain when cannonballs fired from British ships appeared to bounce off its thick wooden hull, as if the ship were made of iron rather than wood. This resilience in battle, combined with its storied history, has made the USS Constitution one of the most famous and revered ships in American naval history.
