For centuries, Hawai‘i’s location in the heart of the Pacific has made it a critical hub for global trade, cultural exchange, and national defense. Today, Hawai‘i remains one of the most strategically significant military locations in the world, hosting key commands from all branches of the U.S. military and serving as the forward edge of defense operations in the Indo-Pacific region.
With growing geopolitical tensions, evolving security threats, and the increasing importance of a free and open Pacific, the U.S. military presence in Hawai‘i is essential to maintaining regional stability, protecting national interests, and ensuring the safety of allies and partners.
Why Hawai‘i is Vital to U.S. and Global Security
U.S. Indo-Pacific Command (USINDOPACOM), the oldest and largest U.S. combatant command, is headquartered at Camp Smith in Hālawa on O`ahu and is the senior U.S. military commander for the Pacific and Indian Ocean areas. It is a joint command comprised of forces from USARPAC, MARFORPAC, PACFLT, PACAF, USSPACEFORINDOPACOM and in times of conflict, the U.S. Coast Guard, part of the Department of Homeland Security. Special Operations Command (SOCPAC), US Forces Korea (USFK) and US Forces Japan (USFJ) also report to USINDOPACOM.
- USARPAC stands for U.S. Army Pacific – oversees Army operations in the region, including Hawai`i, Alaska, Japan, and South Korea.
- MARFORPAC stands for U.S. Marine Forces Pacific – Oversees Marine Corps forces from the waters off the west coats of the United States to the western border of India, and from Antarctica to the North Pole.
- PACFLT stands for U.S. Pacific Fleet (Navy) – commands naval forces in the Pacific, covering nearly half the Earth’s surface, encompassing approximately 100 million square miles.
