The USS Constitution, affectionately known as Old Ironsides, is a historic symbol of the United States Navy's early years. Launched in 1797, it is the world's oldest commissioned naval vessel still afloat. This majestic ship earned its nickname during the War of 1812 when enemy cannonballs were seen bouncing off its resilient wooden hull. Today, the USS Constitution continues to serve as a powerful reminder of American naval heritage and resilience, housed at the Charlestown Navy Yard in Boston, Massachusetts.
