Headquarters, United States Indo-Pacific Command
The United States Indo-Pacific Command (USINDOPACOM) Area of Responsibility (AOR) encompasses about half the earth's surface, stretching from the waters off the west coast of the U.S. to the western border of India, and from Antarctica to the North Pole. There are few regions as culturally, socially, economically, and geo-politically diverse as the Asia-Pacific. The 36 nations that comprising the Asia-Pacific region are home to more than 50% of the world's population, 3,000 different languages, several of the world's largest militaries, and five nations allied with the U.S. through mutual defense treaties. Two of the three largest economies are located in the Asia-Pacific along with 10 of the 14th smallest. The AOR includes the most populous nation in the world, the largest democracy, and the largest Muslim-majority nation. More than one third of Asia-Pacific nations are smaller, island nations that include the smallest republic in the world and the smallest nation in Asia.
USINDOPACOM is one of six geographic Unified Combatant Commands of the United States Armed Forces. Commander, U.S. Indo-Pacific Command (CDRUSINDOPACOM) is the senior U.S. military authority in the Indo-Pacific Command AOR. CDRUSINDOPACOM reports to the President of the United States through the Secretary of Defense and is supported by four component commands: U.S. Pacific Fleet, U.S. Pacific Air Forces, U.S. Army Pacific and U.S. Marine Forces, Pacific. These commands are headquartered in Hawai'i and have forces stationed and deployed throughout the region.
Approximately 375,000 U.S. military and civilian personnel are assigned to the USINDOPACOM area of responsibility.

USINDOPACOM protects and defends, in concert with other U.S. Government agencies, the territory of the United States, its people, and its interests. With allies and partners, USINDOPACOM is committed to enhancing stability in the Asia-Pacific region by promoting security cooperation, encouraging peaceful development, responding to contingencies, deterring aggression, and, when necessary, fighting to win. This approach is based on partnership, presence, and military readiness.
USINDOPACOM recognizes the global significance of the Asia-Pacific region and understands that challenges are best met together. Consequently, USINDOPACOM will remain an engaged and trusted partner committed to preserving the security, stability, and freedom upon which enduring prosperity in the Asia-Pacific region depends.
