The USS Yorktown (1839) was a 16-gun sloop-of-war constructed for the United States Navy, representing a class of third-rate warships designed under the authority of the Congressional Act of 3 April 1837. Laid down in 1838 at the Norfolk Navy Yard and launched on 17 June 1839, she was commissioned on 15 November 1840 under Commander John H. Aulick. The vessel measured significant for her time, featuring a schooner-like design typical of third-class sloops, and was armed with 16 guns, though specific dimensions are not provided in the source. Her service commenced with a voyage from Hampton Roads on 13 December 1840, heading to the Pacific via Rio de Janeiro, Cape Horn, and arriving at Valparaíso, Chile, in March 1841. She operated along the South American coast, including stops at the Marquesas, Society Islands, New Zealand, and Hawaii, primarily tasked with protecting American commerce and the whaling industry. After her South and Central Pacific patrols, she returned to the U.S., arriving in San Francisco in October 1842, and later decommissioned briefly in August 1843. Recommissioned in August 1844 under Commander Charles H. Bell, Yorktown joined the Africa Squadron, focusing on anti-slavery patrols along the west coast of Africa. She captured several slave ships during this period, including Pons, Panther, and Patuxent, demonstrating her maritime significance in suppressing the transatlantic slave trade. She was decommissioned again in June 1846 but was recommissioned in November 1848 for a second African Squadron deployment, continuing her anti-slavery patrols. Her service ended abruptly when she struck an uncharted reef off Maio Island in the Cape Verde Islands on 6 September 1850. The ship quickly broke up in the wreck, but remarkably, no lives were lost. The crew remained on Maio for over a month before being rescued by USS Dale and transferred to Norfolk. The wreck site was later the subject of archaeological interest, with artifacts recovered in 1999, though these remain U.S. government property under maritime law. The USS Yorktown's career highlights her role in early American naval presence, anti-slavery efforts, and Pacific exploration.
