HMS Pictou (1813) in the context of "USS Constitution"

USS Constitution, also known as Old Ironsides, is a three-masted wooden-hulled heavy frigate of the United States Navy. She is the world's oldest commissioned warship still afloat. She was launched in 1797, one of six original frigates authorized for construction by the Naval Act of 1794 and the third constructed. The name "Constitution" was among ten names submitted to President George Washington by Secretary of War Timothy Pickering in March or May for the frigates that were to be constructed. Joshua Humphreys designed the frigates to be the young Navy's capital ships, and so Constitution and her sister ships were larger and more heavily armed and built than standard frigates of the period. She was built at Edmund Hartt's shipyard in the North End of Boston, Massachusetts. Her first duties 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 with the United Kingdom, when she captured numerous British merchantmen and five warships: HMS Guerriere, Java, Pictou, Cyane, and Levant. The capture of Guerriere earned her the nickname "Old Ironsides", adding on the public adoration that had repeatedly saved her from scrapping. She continued to serve as flagship in the Mediterranean and African squadrons, and she 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.
