In 1827, "Peacock" was severely damaged in an attack by a whale. Upon return to New York in October 1827, she was decommissioned and broken up in 1828. She was rebuilt as "Peacock" (1828), to serve as an exploration ship of the United States Exploring Expedition. Jones was to have commanded the expedition, but lack of funding delayed the expedition until 1838, by which time he had resigned the appointment.
