U.S. Naval Communications Station San Miguel (NAVCOMSTAPHIL), also, Naval Station San Miguel was a facility of the United States Navy located in San Antonio, Zambales, The Philippines. During the Vietnam War, all communications from Vietnam to the United States Mainland was routed first through here by an undersea cable from Nha Trang, and was then forwarded to Naval Link Station Mount Santa Rita then to the HF transmitter site at the Naval Communication Transmitting Facility, Capas in Tarlac.
Besides being a Navy facility, the base also housed a Marine barracks.
The U.S.Naval Communication Facility Philippines, as a command, had been established in the Philippines for many years. Construction at San Miguel began in early 1955. The preactivation detail moved to San Miguel from Sangley Point RP in July 1957 and the balance of the officers and men moved in increments. In January 1958 operations at Sangley Point were terminated and full scale operations at San Miguel commenced.
The base was named for the tiny fishing village of San Miguel which is adjacent to the southern end of the station. The base is located in a semicircular bowl of 1,737 acres (7.03 km2), surrounded by mountains on three sides, and the South China Sea on the fourth.(1)
After its turnover to the Philippine Navy (PN), the PN subsequently transferred its Naval Training Command from Fort San Felipe, Cavite to Naval Station San Miguel. It is now the home of the Philippine Navy's Naval Education and Training Command.
