"The operating forces commanders and fleet commanders have a dual chain of command. Administratively, they report to the Chief of Naval Operations and provide, train, and equip naval forces. Operationally, they provide naval forces and report to the appropriate Unified Combatant Commanders. Commander Fleet Forces Command commands and controls fleet assets on both the Atlantic and Pacific coasts for interdeployment training cycle purposes. As units of the Navy enter the area of responsibility for a particular Navy area commander, they are operationally assigned to the appropriate numbered fleet. All Navy units also have an administrative chain of command with the various ships reporting to the appropriate Type Commander." [navy.mil/ navydata/ organization/ orgopfor.asp]
The org chart sample "US Navy operating forces" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the 25 Typical Organizational Charts solution from the Management area of ConceptDraw Solution Park.
