US Navy shore establishment commands exist to support the mission of the seaborne fleets through the use of facilities on land. Focusing on logistics and combat-readiness, they are essential for the smooth, continuous and complete operation of naval forces. The variety of commands reflect the complexity of the modern US Navy and range from naval intelligence to personnel training to maintaining repair facilities. Two of the major logistics and repair commands are Naval Sea Systems Command and Naval Air Systems Command. Other commands such as the Office of Naval Intelligence, the United States Naval Observatory, and the Naval War College focus on intelligence and strategy. Training commands include the Naval Strike and Air Warfare Center and the United States Naval Academy.

The Navy maintains several "Naval Forces Commands" which operate naval shore facilities and serve as liaison units to local ground forces of the Air Force and Army. Such commands are answerable to a Fleet Commander as the shore protector component of the afloat command. During times of war, all Naval Forces Commands augment to become task forces of a primary fleet. Some of the larger Naval Forces Commands in the Pacific Ocean include Commander Naval Forces Korea (CNFK), Commander Naval Forces Marianas (CNFM), and Commander Naval Forces Japan (CNFJ).
