USS Constitution is the world’s oldest commissioned warship afloat and America’s Ship of State.

She played a crucial role in the Barbary Wars and the War of 1812, actively defending sea lanes from 1797 to 1855. The active-duty Sailors stationed aboard USS Constitution provide free tours and offer public visitation as they support the ship’s mission of promoting the Navy’s history and maritime heritage and raising awareness of the importance of a sustained naval presence.

USS Constitution was undefeated in 33 at sea engagements with opponents. The ship earned the nickname of Old Ironsides during the War of 1812 when British cannonballs were seen bouncing off the ship’s wooden hull.
