Kriegsmarine
Command structure
Adolf Hitler was the Commander-in-Chief of all German armed forces, including the "Kriegsmarine". His authority was exercised through the "Oberkommando der Marine", or OKM, with a Commander-in-Chief ("Oberbefehlshaber der Kriegsmarine"), a Chief of Naval General Staff ("Chef des Stabes der Seekriegsleitung") and a Chief of Naval Operations ("Chef der Operationsabteilung"). The first Commander-in-Chief of the OKM was Erich Raeder who was the Commander-in-Chief of the "Reichsmarine" when it was renamed and reorganized in 1935. Raeder held the post until falling out with Hitler after the German failure in the Battle of the Barents Sea. He was replaced by Karl Dönitz on 30 January 1943 who held the command until he was appointed President of Germany upon Hitler's suicide in April 1945. Hans-Georg von Friedeburg was then Commander-in-Chief of the OKM for the short period of time until Germany surrendered in May 1945.

Kriegsmarine [SEP] Destroyers
Although the German World War II destroyer ("Zerstörer") fleet was modern and the ships were larger than conventional destroyers of other navies, they had problems. Early classes were unstable, wet in heavy weather, suffered from engine problems and had short range. Some problems were solved with the evolution of later designs, but further developments were curtailed by the war and, ultimately, by Germany's defeat. In the first year of World War II, they were used mainly to sow offensive minefields in shipping lanes close to the British coast.
