There are three Military Departments within the Department of Defense: the Department of the Army, which the United States Army is organized within. the Department of the Navy, which the United States Navy and the United States Marine Corps are organized within.
The Navy is administratively managed by the Department of the Navy, which is headed by the civilian Secretary of the Navy. The Department of the Navy is itself a division of the Department of Defense, which is headed by the Secretary of Defense. The Chief of Naval Operations (CNO) is a four-star admiral and the senior naval officer of the Department of the Navy.
