Radio Barrigada, formally Communications Site Barrigada and previously Communications Annex Barrigada,[1] refers to two adjacent U.S. military transmitter facilities located in the villages of Barrigada and Mangilao on the western Pacific territory of Guam. The larger facility is Naval Computer and Telecommunications Site (NCTS) Barrigada, operated by Naval Base Guam,[2] located entirely within Barrigada.
To its south, the Barrigada Transmitter Site, operated by Andersen Air Force Base, lies partially within Mangilao. The installation itself is managed by Joint Region Marianas. Radio Barrigada is the counterpart to the telecommunications receiving site Naval Computer and Telecommunications Station Guam, located to the north in Finegayan, Dededo. Located near the high point of Mount Barrigada, Radio Barrigada comprises 1,800 acres (7.3 km2).[1]
