USS Constitution

This frigate of the U.S. Navy with its wooden hull and three masts was personally named by George Washington himself. She is currently the world's oldest navy ship that is commissioned and floating on water. She is also the oldest active American ship to have sunk an enemy vessel. She was put into service in 1787 and saw many battles before she was retired in the late 1800s. Now, with all of her accolades, she lives out her golden years as a type of floating ambassador - a diplomatic vessel used to promote the mission of the U.S. Navy.
