The USS Nantucket was a Passaic-class coastal monitor constructed for the United States Navy during the American Civil War. Launched on December 6, 1862, by Atlantic Iron Works in Boston, Massachusetts, the vessel was commissioned on February 26, 1863, under the command of Commander Donald McNeil Fairfax. As a single-turreted monitor, the Nantucket was designed for coastal and blockade duty, featuring heavy armor and a low freeboard typical of the Passaic class, optimized for riverine and near-shore operations. During its service, the Nantucket was assigned to the South Atlantic Blockading Squadron, playing a prominent role in the Union effort to blockade Confederate ports. Notably, on April 7, 1863, she participated in the attack on Confederate forts in Charleston Harbor, enduring 51 hits in a fierce but unsuccessful assault. After repairs at Port Royal, she returned to Charleston to support Army activities on Morris Island, engaging Confederate defenses at Fort Wagner on multiple occasions in July 1863. The Nantucket also captured the British steamer Jupiter at sea on September 15, 1863, highlighting her role in enforcing the blockade. She continued her operations in Charleston Harbor, challenging Confederate defenses again on May 14, 1864, and remained on blockade duty until the end of the Civil War. Decommissioned on June 24, 1865, at Philadelphia Navy Yard, the vessel remained inactive for a decade. She was renamed Medusa on June 15, 1869, but reverted to Nantucket on August 10, 1869. Throughout the 1870s and early 1880s, she was intermittently recommissioned for operations along the North Atlantic coast, including brief periods in 1882 and 1884. She also served at Port Royal during the Spanish–American War. Eventually deemed unfit for further service, the Nantucket was sold at auction in Washington, D.C., on November 14, 1900, for $13,111. Her sale drew public interest due to her historic significance as a Civil War-era monitor, marking the end of her maritime service life.
