Andersen Air Force Base — Yigo, Guam

Andersen Air Force Base is a major United States military installation located on the northern part of Guam, a strategically vital American territory in the western Pacific Ocean. UAM serves exclusively military functions, supporting long-range bomber operations, refueling missions, and force projection capabilities central to United States defense posture across the Indo-Pacific region. The base has hosted various aircraft types over decades and plays a key role in regional deterrence strategy given Guam's proximity to East Asia. Unlike civilian airports, Andersen operates under military command with restricted access limited to authorized defense personnel and associated operations. Its scale and infrastructure reflect Guam's importance as a forward operating location for American Pacific military presence.
