The USS Kansas was a screw steam gunboat built for the Union Navy during the American Civil War, representing an early class of 836-ton vessels designed for blockade duty. Constructed at the Philadelphia Navy Yard, she was launched on September 29, 1863, with machinery salvaged from the prize steamer Princess Royal. Commissioned on December 21, 1863, under Lieutenant Commander Pendleton G. Watmough, she was immediately tasked with joining the North Atlantic Blockading Squadron, although engine and boiler issues initially delayed her deployment. The vessel saw extensive service primarily off Wilmington, North Carolina, where she engaged Confederate vessels and supported blockade operations. Notably, on May 6, 1864, Kansas participated in the engagement that forced the Confederate ironclad Raleigh to withdraw after grounding. She also captured the blockade runner Tristram Shandy on May 15, 1864, and contributed to the preparations for the Union attack on Fort Fisher, participating in the famous bombardments and the subsequent Union assault in January 1865. Throughout the war, Kansas played a vital role in naval operations, including supporting landings, bombarding Confederate defenses, and maintaining blockade integrity. Her involvement in the final assault on Fort Fisher was particularly significant, as she provided heavy naval fire that helped secure the fort's fall, marking a decisive Union victory. After the Civil War, Kansas continued her service, including survey missions and diplomatic port calls, such as at Cape Town and in the Caribbean. She also took part in scientific expeditions, notably surveying the Isthmus of Tehuantepec for an inter-oceanic canal route. During her peacetime service, she was involved in various missions like cable positioning, showing her versatility beyond combat. Decommissioned in 1875, Kansas was recommissioned in 1870 and again in 1872, serving until her final decommissioning in 1875. She was sold in 1883 at Rockland, Maine. Her service history highlights her importance in Civil War naval operations and her contribution to maritime exploration and diplomacy in the post-war era.
