The second Porpoise, a hermaphrodite brig, was authorized by Congress 30 Jlme 1834, built in 1835, and 1aunched 31 May 1836, Lt. William Ramsay in command.

Porpoise sailed from Boston 2S August 1836, called at various southern ports, and conducted coastal surveying operations under the direction of Lt. Charles Wilkes in the summer of 1837. In October 1837 she hunted pirates along the southern coast, and then resumed her survey work in December.

Porpoise, Lt. Cadwallader Ringgold in command, was then assigned to the squadron which Wilkes was to command on an extended exploratory expedition around the world. She stood out of Hampton Roads 18 August 1838 with the United States Exploring Expedition Squadron. She assisted in the exploration and survey work of the Expedition as it confirmed the existence of the Antarctic Continent, charted vast areas of the South Pacific, circumnavigated the world, and returned to New York four years later.

Porpoise underwent overhaul at New York at the end of 1842 and sailed 8 February 1843 for the west coast of Africa to join the squadron patrolling for slavers. She returned to New York 19 November 1844.

Between February 1845 and July 1847, Porpoise cruised in the Gulf of Mexico, participating in the Naval operations against Tampico, Panuco, and Vera Cruz during the War with Mexico. Upon return to Norfolk, she decommissioned until 1 January 1848.

During the next three and a half years she hunted slavers along the west coast of Africa, touching at the United States in the spring of 1850. Returning to New Yurk from this extended cruise 19 December 1851. She again decommissioned 3 August 1852.

Recommissioned in May 1853, she was assigned to an exploring squadron under Comdr. Cadwallader Ringgold, a veteran, like Porpoise, of the Wilkes Expedition. She joined the squadron at Hampton Roads, and with it, stood out to sea 11 June 1853. Porpoise rounded the Cape of Good Hope, and with the squadron explored and charted many Pactfic islands and shoals before arriving in China in March 1854. The squadron put to sea once more to explore in the Bonins, the Ladrones, and the Marianas. Porpoise parted company with the other vessels 21 September 1854 between Formosa and China, and was never heard from again. It is supposed that she foundered in a heavy typhoon which occurred a few days after her separation from the squadron.
