U.S. Initial Order of Battle

Unit	Commander	Start	Administrative Assignment	Operational Assignment	Notes
Joint Chiefs of Staff	Franklin D. Roosevelt				Under the U.S. Constitution, the President of the United States is the Commander-in-Chief of all military forces. At the time of the attack on Pearl Harbor, Roosevelt exercised this power through the service chiefs, but the need for better interservice cooperation prompted the establishment of the Joint Chiefs of Staff as a formal body on 9 February 1942.
United States Navy	Harold R. Stark		Joint Chiefs of Staff		Stark was Chief of Naval Operations. This was initially distinct from Commander, U.S. Fleet, who was Kimmel. The offices were merged under King later in the war.
Pacific Fleet	Husband E. Kimmel	Pearl Harbor	United States Navy		Kimmel was officially Commander, U.S. Fleet, but had effective command only over the Pacific Fleet. This confused command arrangement was resolved by making King both Chief of Naval Operations and Commander, U.S. Fleet, and making Nimitz Commander, Pacific Fleet.

Asiatic Fleet	Thomas C. Hart	Manila	United States Navy		Responsible for patrolling U.S. possessions in the Far East. With no unit larger than a cruiser, it could not possibly stand up for long against Combined Fleet, and in fact the Philippines had been effectively written off in Navy pre-war planning. With the destruction of MacArthur's air power on the first day of the war, Hart withdrew all his forces except for submarines and some small units. This created lasting bitterness in MacArthur towards the Navy.
