Seekriegsleitung

The Seekriegsleitung or SKL (Maritime Warfare Command) was a higher command staff section of the Kaiserliche Marine and the Kriegsmarine of Germany during the World Wars.

World War I
The SKL was established on August 27, 1918, on the initiative of Admiral Reinhard Scheer, who became its first commander, simultaneously to being the Chief of the German Imperial Admiralty Staff. It led the planning and execution of naval combat and directed the distribution of naval forces. Up to this point, that was done by several staffs and the individual theater commanders. When the war ended, the SKL was absorbed into the admiralty.

World War II
The SKL was reestablished in 1937 and deeply linked in the Naval High Command, the Commander-in-Chief also being the commander of the SKL with the Commander of the Naval Command Department (Marinekommandoamt) as the Chief of Staff. Though the competences of the SKL initially were equal to their role in World War I, they were narrowed when the Naval Command Department was split from it. The command was limited to except-domestic sea-areas, where the naval group commands did not possess the operational guidance. Also, the submarine war split and were, under the Commander of the submarines (Befehlshaber der U-Boote), directly subordinate to the Commander-in-Chief. In 1944, the SKL was tasked with the command of fleet units operating as transports, blockade runners, auxiliary cruisers and supply shipping.
