The Grand Admiral's Council is the ruling body of the Imperial Navy in the Galactic Empire. Overseen by the Chief of Naval Operations, the Council is responsible for the management, direction and upkeep of the Imperial Navy and the war planning for the Navy (usually in conjunction with the Imperial Army and other Imperial units).
Twelve Grand Admirals comprise the Council, with one serving as the Chief of Naval Operations (or Chief Naval Officer), who is considered the official head of the Imperial Navy. Alongside the Grand General's Council, the Grand Admiral's Council is primarly responsible for the war effort against the New Republic. The Council is under the overall direction of the Commander-in-Chief, the Military Executor and Supreme Commander of the Imperial Forces, who also oversees the Grand General's Council and is the head of the Imperial Military.
The Council is higher in authority than the Imperial Ruling Council and the Moff's Council, though in the case of the Imperial Ruling Council it is more of a formality, and the Council generally does not interfere with the Moff's Council.Alongside the Moff's Council, the Grand General's Council and the Commander-in-Chief, the Grand Admiral's Council comprises Imperial High Command.
