The Beiyang Fleet also possessed an array of small torpedo boats. Exact numbers are uncertain, because these craft were not systematically listed, but some details are known. Four 16-ton torpedo boats were built in 1883 at the Vulcan yard in Stettin for the use of the steel battleships "Dingyuan" and "Zhenyuan". These four craft, known respectively as "Dingyuan" No. 1 and No. 2 and "Zhenyuan" No. 1 and No. 2, were delayed in harbour by the Germans during the Sino-French War along with their mother ships, and joined the Beiyang Fleet in October 1885.
