USS Boxer and 11th MEU Deliver Post-Typhoon Relief to Guam and Northern Marianas

U.S. sailors and Marines assigned to the USS Boxer Amphibious Ready Group and the 11th Marine Expeditionary Unit provided direct support to civil and local authorities in Guam and the Northern Mariana Islands for recovery efforts following Super Typhoon Sinlaku, according to a May 7, 2026, release from U.S. Central Command.

The assistance reached populations across the two U.S. territories. Guam is home to approximately 170,000 residents while the Commonwealth of the Northern Mariana Islands has roughly 47,000. The joint force contributed personnel, equipment and logistics capacity that local governments otherwise would have sourced solely through Federal Emergency Management Agency channels and contracted civilian providers.

The deployment shifts the operational posture from routine patrol and training to immediate humanitarian support. The Boxer ARG and 11th MEU, already positioned in the Western Pacific, diverted assets to the affected islands once the typhoon passed. The change took effect in the days immediately after the storm made landfall, with no fixed end date listed in the CENTCOM release.

Downstream effects include faster clearance of debris from ports and airfields, which keeps commercial shipping and military resupply lines open on tighter timelines. Local governments now coordinate directly with embarked Marine and Navy units rather than waiting for additional FEMA teams to arrive from the continental United States.

The effort also triggers standard after-action reviews that will inform future Department of Defense humanitarian assistance protocols for Pacific island territories under the existing Defense Support of Civil Authorities framework.

This marks the latest instance of U.S. naval forces executing disaster relief in the Pacific theater. The Boxer ARG and 11th MEU previously supported similar operations after typhoons in the region, consistent with standing Department of Defense policy that assigns forward-deployed amphibious units as first responders when U.S. territories are impacted.

The CENTCOM daily release shows the joint force operated in coordination with territorial authorities rather than in a lead role.
