Claim: The USS Constitution was a ship in the navy.

USS Constitution is a wooden-hulled , three-masted heavy frigate of the United States Navy , named by President George Washington after the Constitution of the United States of America . She is the world 's oldest commissioned naval vessel afloat . Constitution was launched in 1797 , one of six original frigates authorized for construction by the Naval Act of 1794 and the third constructed . Joshua Humphreys designed the frigates to be the young Navy 's capital ships , and so Constitution and her sisters were larger and more heavily armed and built than standard frigates of the period . Constitution was built in the North End of Boston , Massachusetts at Edmund Hartt 's shipyard . Her first duties with the newly formed U.S. Navy were to provide protection for American merchant shipping during the Quasi-War with France and to defeat the Barbary pirates in the First Barbary War .   Constitution is most noted for her actions during the War of 1812 against the United Kingdom , when she captured numerous merchant ships and defeated five British warships : , , , , and . The battle with Guerriere earned her the nickname of `` Old Ironsides '' and public adoration that has repeatedly saved her from scrapping . She continued to serve as flagship in the Mediterranean and African squadrons , and circled the world in the 1840s . During the American Civil War , she served as a training ship for the United States Naval Academy . She carried American artwork and industrial displays to the Paris Exposition of 1878 .   Constitution was retired from active service in 1881 , and served as a receiving ship until designated a museum ship in 1907 . In 1934 , she completed a three-year , 90-port tour of the nation . Constitution sailed under her own power for her 200th birthday in 1997 , and again in August 2012 to commemorate the 200th anniversary of her victory over Guerriere .   Constitutions stated mission today is to promote understanding of the Navy 's role in war and peace through educational outreach , historical demonstration , and active participation in public events as part of the Naval History & Heritage Command . As a fully commissioned U.S. Navy ship , her crew of 60 officers and sailors participate in ceremonies , educational programs , and special events while keeping Constitution open to visitors year round and providing free tours . The officers and crew are all active-duty U.S. Navy personnel and the assignment is considered to be special duty in the U.S. Navy . Traditionally , command of the vessel is assigned to a Navy commander . She is usually berthed at Pier 1 of the former Charlestown Navy Yard , at one end of Boston 's Freedom Trail . In May 2015 , Constitution entered Dry Dock 1 to begin a three-year restoration program .
