SMS "Delphin" was a of the Prussian Navy (later the Imperial German Navy) that was launched in 1860. A small vessel, armed with only three light guns, "Delphin" served during the Second Schleswig War of 1864 and the Austro-Prussian War of 1866, part of the conflicts that unified Germany. The ship was present at, but was only lightly engaged in the Battle of Jasmund during the Second Schleswig War. The ship spent much of the rest of her career in the Mediterranean Sea, going on three lengthy deployments there in 1865–1866, 1867–1870, and 1871–1873. During the last tour, she took part in operations off the coast of Spain with an Anglo-German squadron during the Third Carlist War, where she helped to suppress forces rebelling against the Spanish government. For the rest of the 1870s, she served as a survey vessel in the North and Baltic Seas before being decommissioned in August 1881, stricken from the naval register the following month, and subsequently broken up for scrap.
