Z17 Diether von Roeder was one of six Type 1936 destroyers built for the Kriegsmarine in the late 1930s. Completed in 1938, the ship spent most of her time training although she did participate in the occupation of Memel in early 1939. At the beginning of World War II in September, the ship was initially deployed to lay minefields off the German coast, but was soon transferred to the Skagerrak where she inspected neutral shipping for contraband goods. In late 1939, the ship helped lay an offensive minefield off the English coast that claimed seven merchant ships.

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.
