Subic Bay International Airport / Naval Air Station Cubi Point — Olongapo, Philippines

Zambales province in the Philippines is home to Subic Bay International Airport, built on part of the former US Naval Base Subic Bay, an American military installation that operated for nearly a century before the United States withdrew in 1992 following the non-renewal of its basing agreement and the destructive eruption of nearby Mount Pinatubo the year before. The base area was subsequently converted into the Subic Bay Freeport Zone, an economic development area combining shipping, industrial, and tourism activity, with SFS serving as its aviation component for cargo charters, general aviation, and limited passenger flights. The airport retains infrastructure built to US military specifications, including long runways designed for naval aircraft, which today support occasional international cargo operations and aircraft maintenance business. Subic Bay's deep natural harbor, a key reason the US Navy chose the site originally, continues to draw shipping and logistics investment to the surrounding freeport zone decades after the military departed.
