Subic Bay

Subic Bay is a large natural bay on the west coast of Luzon in the Philippines, on the border of Zambales and Bataan provinces. It is a deep-water harbour that was heavily developed in the 20th century for naval and industrial use.

The area includes extensive port and ship-repair facilities, coastal beaches and dive sites used for tourism, and a designated economic zone known as the Subic Bay Freeport Zone. The bay’s protected waters and infrastructure make it important for shipping and maritime services.

During the 20th century Subic Bay hosted the U.S. Naval Base Subic Bay; the base closed in 1992 and much of the area was converted into the Freeport Zone and commercial facilities. Since then the zone has been repurposed for civilian industry, logistics, tourism and port activities.

Subic Bay lies on Luzon’s western coastline, roughly northwest of Metro Manila by road, with the main urban area of Olongapo and the Freeport Zone occupying the bay’s shoreline. The surrounding landscape includes coastal plains and nearby mountainous terrain inland.

• Former U.S. naval base: Formerly the location of a major U.S. naval base until its closure in 1992; the facilities were later converted into a commercial freeport and mixed-use zone.
• Natural deep harbour: The bay's deep, sheltered waters make it a natural deep-water harbour and a regional centre for ship repair and maritime logistics.
