Operation Unified Assistance

Operation Unified Assistance is the name of the United States military's response to the 2004 Indian Ocean tsunami.

On 28 December, the first elements of the Combined Support Force (CSF-536) were deployed to Utapao, Thailand following that country's approval of the use of that base.

More than 12,600 Department of Defense personnel were involved in the relief effort.

The United States offered assistance from its troops stationed in Japan.

The United States military participated in the Combined Coordination Center.

The United States dispatched numerous C-5 Galaxy and C-17 Globemaster III strategic airlifters and ten C-130 Hercules tactical airlifters containing disaster supplies, nine P-3C Orion maritime patrol aircraft for search and rescue support, and several teams from the Departments of State and Defense to coordinate additional assistance. They are using Utapao Naval Air Base in Thailand as their regional hub. The deployment of the 615th Air Mobility Operations Group from Travis Air Force Base, California, established a tanker airlift control element where personnel assisted with the safe movement of 6,685 passengers, 5,444 cargo tons of relief supplies and medical aid on 817 airlift missions.
