U.S. Naval Base Subic Bay
The economic zone was the location of U.S. Naval Base Subic Bay, until the latter's decommissioning in 1992. The SBFZ is operated and managed by the Subic Bay Metropolitan Authority (SBMA), an sub-agency under Bases Conversion and Development Authority (BCDA). The harbor faces the Zambales Mountains to the west and the Subic Bay opening to the South China Sea.
