The USS Yuma was a single-turreted, twin-screw monitor constructed during the American Civil War era. Laid down in Cincinnati, Ohio, by Alexander Swift and Co., she was launched on May 30, 1865. As a Casco-class, light-draft monitor, she was specifically designed for operations in shallow waters such as bays, rivers, and inlets of the Confederacy. The design prioritized a shallow draft over armor protection, featuring a ballast compartment that could be flooded to lower the vessel during combat, enhancing stability and survivability in shallow environments. The vessel's design was based on plans initially drawn by renowned engineer John Ericsson, but these were significantly revised by Chief Engineer Alban C. Stimers following the failed Union bombardment of Fort Sumter in 1863. Due to poor relationships and oversight issues, these revisions were approved without thorough review, leading to construction flaws. Notably, Stimers' modifications did not account for added armor weight, causing excessive stress on the wooden hull and limiting freeboard to only 3 inches (76 mm), which threatened seaworthiness. Ericsson was later brought in to rectify these issues by raising the hulls of the monitors by 22 inches (560 mm), a process carried out in 1866. Although alterations addressed these structural deficiencies, USS Yuma never saw active service. She was laid up from 1866 to 1874 and underwent two name changes during this period, first to Tempest in June 1869 and then back to Yuma in August of the same year. Ultimately, the vessel was sold at auction to Theodore Allen in New Orleans on September 12, 1874. The USS Yuma's construction and design issues reflect the hurried and experimental nature of Civil War-era naval engineering, representing a significant chapter in the development of shallow-draft armored vessels.
