The USC&GS Arago was a survey vessel constructed in 1854 by Fardy and Brothers in Baltimore, Maryland. Designed for hydrographic and topographical survey work along the Atlantic coast, she was a notable vessel of the United States Coast Survey, later serving in the Coast and Geodetic Survey until her sale in 1881. The ship was the first to bear the name Arago within these agencies. Arago was actively engaged in detailed surveying operations along the U.S. Atlantic coastline, including Maine, South Carolina, and North Carolina. Her early service included triangulation, hydrography, and topography, notably in Passamaquoddy Bay, Maine. During the Civil War, she was temporarily armed and under Treasury Department control, assisting in the seizure of blockade runners and maintaining naval communications. In 1861, she joined the South Atlantic Blockading Squadron to support naval operations in South Carolina waters, contributing to the seizure of ships like Express, Orizimba, and Alice Ball. She also provided vital hydrographic support during military campaigns, including the expedition to seize Port Royal, South Carolina. Throughout her service, Arago was involved in numerous survey missions, including passages between St. Helena and Port Royal Sounds to aid naval communication, as well as surveys of Maine harbors and the Hudson River. In 1867, she sustained damage after striking Confederate defense stakes in North Carolina but was quickly repaired within ten days, thanks to efficient efforts by her crew. From 1869 onward, she primarily operated along the North Carolina coast, conducting surveys in bays and rivers such as Pamlico, Albemarle, and Currituck. Her service was characterized by consistent hydrographic and topographical mapping critical for navigation and military operations. She was laid up at League Island, Pennsylvania, in 1881 and subsequently sold. The USC&GS Arago remains a significant vessel for her long-standing contributions to U.S. maritime navigation and coast survey efforts during a pivotal era of coastal development and wartime support.
