The USS Nahant was a Passaic-class ironclad monitor of the United States Navy, launched on October 7, 1862, by Harrison Loring in South Boston, Massachusetts. She was commissioned on December 29, 1862, under the command of Commander John Downes. As a single-turreted monitor, Nahant was designed for coastal and riverine operations, featuring heavy armor and a low freeboard characteristic of Civil War ironclads. During the American Civil War, Nahant served primarily in the South Atlantic Blockading Squadron. Her first engagement was the Union bombardment of Fort McAllister on March 3, 1863. Shortly afterward, she participated in the attack on Charleston Harbor, a significant but ultimately unsuccessful engagement. During this action, Nahant sustained heavy damage—being hit 36 times, which disabled her turret and caused internal damage, including the loss of her helmsman and injuries to her pilot and other crew members. Throughout the war, Nahant was involved in various operations, including supporting landings on Morris Island and bombarding Confederate defenses. Notably, she participated in the capture of the Confederate ironclad ram CSS Atlanta in June 1863, engaging its crew and assisting in its surrender after the Confederate flagship ran aground. The vessel also took part in shelling blockade runners, such as the Presto in February 1865, which was destroyed after being run ashore. Following the war, Nahant was decommissioned in August 1865 and briefly renamed Atlas in 1869 before reverting to her original name. She was recommissioned in 1898 for harbor defense during the Spanish–American War. The vessel was decommissioned again and sold in 1904. Her service history underscores her role as a significant Civil War ironclad, notable for her participation in key naval engagements and her contribution to Union blockade efforts.
