USS Constellation (1854)

USS Constellation is a sloop-of-war/corvette, the last sail-only warship designed and built by the United States Navy. She was built in 1854, using some materials salvaged from the frigate USS Constellation, which had been disassembled the year before. Despite being a single-gundeck "sloop," she is actually larger than her original frigate build, and more powerfully armed with fewer but much more potent shell-firing guns.The sloop was launched on 26 August 1854 and commissioned on 28 July 1855 with Captain Charles H. Bell in command. She remained in service for close to a century before finally being retired in 1954. She is now preserved as a museum ship in Baltimore, Maryland, and is a National Historic Landmark.
