HMS Arno was a unique destroyer of the Royal Navy that served during the First World War. Originally under construction in Genoa, Italy, in 1914 for the Portuguese Navy and named Liz, she was acquired by the Royal Navy before completion, intended for service in the Mediterranean. The vessel featured a distinctive design with two funnels and two masts, complemented by a relatively small size and slower speed compared to her British counterparts. Despite these limitations, she was well-constructed, boasting a high freeboard and a tall bridge, which contributed to her seaworthiness and operational usefulness. Armament on HMS Arno consisted of four QF 12-pounder guns, strategically positioned with two on the forecastle, one behind the second funnel, and one on the quarterdeck. Her layout and armament made her a capable vessel within her class, although her smaller size and slower pace distinguished her from other destroyers of the period. Her build quality and design features, such as the high freeboard, allowed her to perform effectively in her assigned roles. HMS Arno’s service was primarily in the Mediterranean theater, where she was involved in patrols and operations during the war. Her service was cut short when she was lost off the Dardanelles after a collision with the H-class destroyer Hope on 23 March 1918. The collision resulted in her sinking, marking a tragic end to her relatively brief career. Overall, HMS Arno represents a distinctive example of wartime naval procurement, originating from an international construction effort and serving in a critical theater of World War I. Her notable features include her unique origin, her compact but sound construction, and her service in one of the most significant naval campaigns of the war.
