The Subic Special Economic and Freeport Zone, often shorterned as Subic Bay or Subic, is a special economic zone and freeport area covering portions of the city of Olongapo and the town of Subic in Zambales, and the towns of Morong and Hermosa in Bataan. The relatively developed and fenced area is called the Subic Bay Freeport Zone (SBFZ).
