FPO AP 96540 serves Naval Base Guam, the primary U.S. Navy installation in the Western Pacific and a critical component of Joint Region Marianas. Located on the southwestern coast of Guam near Santa Rita, the base provides vital logistics, maintenance, and operational support for submarine and surface fleet operations throughout the Indo-Pacific region. The installation is home to Commander Submarine Squadron 15, which oversees attack submarine operations forward-deployed to Guam.
Naval Base Guam supports over 28 tenant commands including Coast Guard Sector Guam, Naval Special Warfare Unit One, and Naval Mobile Construction Battalion Camp Covington. The base's strategic location places it approximately 1,500 miles from Manila, Tokyo, and Hong Kong, making it an essential staging point for Pacific operations. Deep-water facilities at Apra Harbor can accommodate aircraft carriers and the Navy's largest vessels.
Mail for personnel at Naval Base Guam routes through the San Francisco International Service Center with typical delivery times of 14-21 days depending on destination within the base complex. The standard address format uses PSC 455 Box numbers with FPO AP 96540-1000. Personnel and their families have access to exchange, commissary, medical facilities, and MWR programs. The tropical climate features consistent warm temperatures and a distinct wet season from July through November.
