The Type 1936 destroyers, also known as the Z17 class, were a group of six destroyers built for Nazi Germany's Kriegsmarine during the late 1930s, shortly before the beginning of World War II. All six sister ships were named after German sailors who had been killed in World War I. They were engaged in training for most of the period between their completion and the outbreak of war, although several did participate in the occupation of Memel in Lithuania, in early 1939.
