SMS Zieten was the first torpedo-armed aviso built for the Imperial German Navy (Kaiserliche Marine). She was built in Britain in 1875–1876, and was the last major warship built for Germany by a foreign shipyard. Ordered as a testbed for the new Whitehead torpedo, Zieten was armed with a pair of 38 cm (15 in) torpedo tubes, and was capable of a top speed of 16 knots (30 km/h; 18 mph), making her the fastest ship in the German fleet at the time. Zieten was the first torpedo-armed vessel in a series of avisos that ultimately developed into the first light cruisers. In addition to her impact in German warship design, Zieten also influenced numerous other navies, who built dozens of similar avisos and torpedo vessels of their own.
