The USS Constellation is a historic naval ship of the United States Navy, launched in 1797. It was the last sail-only warship built for the U.S. Navy and played a significant role in the early years of American naval history. The ship is known for its impressive speed and agility, which made it a formidable opponent during the Quasi-War with France and the Barbary Wars. Today, the USS Constellation is preserved as a museum ship located in the harbor of Baltimore, Maryland. It serves as a reminder of the naval heritage of the United States and offers visitors a glimpse into life at sea during the 19th century. The ship is part of the Historic Ships in Baltimore collection, which includes other notable vessels.
