List of major activeUS Navy bases, stations and other facilities. Formally established by General Order No 135 (1911), the following primary types of bases are defined:[1]
Naval Station: any establishment for building, manufacturing, docking, repair, supply, or training under the control of the Navy.
Navy Yard: a single establishment for docking, repair, and supply. It may include building and manufacturing facilities. Either alone or with other naval establishments it constitutes a naval station.
Naval Base: is a point from which naval operations may be conducted and which is selected for that purpose. Its essential feature is an adequate anchorage for a fleet with its auxiliaries, preferably sheltered from the sea and fortified against attack. A temporary base would generally be established nearer the theater of war than any permanent base (also referred to as an advanced base). A permanent base would have docking and repair facilities.
In January 2024, the US Navy requested a new permit for the installation and maintenance of mine training areas off the coasts of Hawaii and Southern California, as the Pacific Ocean, according to the command, is a priority theater of operations amid tensions with China. The current permit expires in 2025 and the Navy is required to submit an environmental impact report to extend it.
