German destroyer Z9 Wolfgang Zenker
 Z9 Wolfgang Zenker was a Type 1934A-class destroyer built for the German Navy (Kriegsmarine) in the mid-1930s. Several days after the start of World War II she unsuccessfully attacked together with another destroyer Polish ships anchored at the naval base on the Hel Peninsula. In early 1940 the ship made two successful minelaying sorties off the English coast that claimed six merchant ships.
