BOSTON (Oct. 21, 2020) 1812 Marines participates in a Facebook live event for the USS Constitution's 223rd birthday. Constitution is the world's oldest commissioned warship afloat, and played a crucial role in the Barbary Wars and the War of 1812, actively defending sea lanes from 1797 to 1855. During normal operations, the active-duty Sailors stationed aboard Constitution provide free tours and offer public visitation to more than 600,000 people a year 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. Constitution was undefeated in battle and destroyed or captured 33 opponents. (U.S. Navy Photo by Electronics Technician 2nd Class Michelle Heintzelman)
