About this Unit
US Naval Base Subic Bay, located in the Philippines, served as one of the United States Navy’s largest overseas military installations from 1901 to 1992. Originally established after the Spanish-American War, the base played a crucial role as a ship repair, supply, and logistics hub, particularly during World War II, the Korean War, and the Vietnam War. Throughout the Cold War, Subic Bay was a strategic anchor for U.S. naval operations in the Pacific, supporting fleet movements and regional security efforts. The base was closed and turned over to the Philippine government in 1992 following the expiration of the U.S.-Philippines Military Bases Agreement and the eruption of Mount Pinatubo.
