The USS Aroostook was a Unadilla-class gunboat constructed for the Union Navy during the American Civil War. This wooden-hulled, steam-powered vessel was designed as a screw gunboat, emphasizing maneuverability and versatility in patrol and combat operations. She was laid down shortly after July 6, 1861, by Nathaniel Lord Thompson in Kennebunk, Maine, and was launched around October 19, 1861. The ship was commissioned at the Boston Navy Yard on February 20, 1862, with Lt. John C. Beaumont in command. The vessel played a significant role in several key naval operations. Initially, Aroostook was tasked with assisting the distressed USS Vermont in March 1862, locating the disabled vessel and shielding her from stormy seas, although she suffered damage herself during the rescue. After repairs, she participated in the blockade and patrol operations along the Atlantic coast, notably during the Battle of Hampton Roads in March 1862, where she was part of the Union fleet confronting the Confederate ironclad Virginia and the Union ironclad Monitor. Aroostook was among the light-draft gunboats used to maneuver in shoal waters inside the Virginia Capes, and her commanding officer, Lt. Beaumont, devised innovative tactics such as attempting to entangle Virginia’s propeller with a net—though this plan was never executed. In May 1862, Aroostook joined a Union naval force ascending the James River, supporting Union Army movements and engaging Confederate batteries at Drewry's Bluff. Throughout her service, she carried messages, supplied Union forces, and gathered intelligence, often engaging shore batteries and silencing enemy guns. She participated in the Siege of Richmond and supported troop movements during the Peninsula Campaign, earning the nickname "Old Rooster" after rescuing runaway slaves. Later, Aroostook was reassigned to the West Gulf Blockading Squadron, operating off Mobile Bay, Alabama, where she engaged blockade runners and supported Union efforts to cut off Confederate supply lines. She continued active duty until September 1865, after which she was decommissioned in Philadelphia. Recommissioned in 1866 for service in the Far East, she arrived in Hong Kong and joined the Asiatic Squadron. Her service included operations against pirates, protecting American nationals during the Japanese civil war, and participating in demonstrations off Honshu. Her career was cut short due to her poorly constructed, inadequately seasoned timber hull, which deteriorated prematurely. She was decommissioned in Hong Kong in September 1869 and sold in October of that year. In 1870, she was briefly used in a rescue mission following the sinking of the USS Oneida. Her varied service record underscores her importance as a versatile vessel during a transformative period in naval warfare and imperial expansion.
