The U.S. Coast Guard and partner forces practiced maritime military operations during the 2026 [1] RIMPAC exercise in Hawaii.

These drills demonstrate how coast guard agencies can integrate with and support larger military operations during multinational naval exercises. By bridging the gap between civilian law enforcement and naval warfare, the participants aim to enhance regional security and interoperability.

The training focused on the specific capabilities that coast guards bring to a military theater. This included coordinating maneuvers and operational strategies designed to showcase the role of coast guard forces in supporting broader military missions [1]. The exercise took place in the RIMPAC training areas off the coast of Hawaii [1].

Leading up to the main event, specific partner forces engaged in preparatory activities. The Philippine Coast Guard and the U.S. Coast Guard completed a series of engagements in Guam from June 9-13, 2026 [2]. These pre-exercise activities served as a foundation for the more complex maneuvers conducted during the primary RIMPAC event later this month [2].

Participants from various nations worked together to refine communication and tactical execution. The collaboration emphasizes the versatility of coast guard vessels, which often operate in the gray zone between diplomatic engagement and military deterrence. This hybrid capability allows the participating nations to scale their response based on the tension level of a given maritime encounter.

Coordination between the U.S. and the Philippine Coast Guard highlights a strategic focus on the Indo-Pacific region. The integration of these forces during the 2026 [1] cycle reflects an ongoing effort to standardize maritime protocols across allied nations.

The inclusion of coast guard forces in RIMPAC signals a shift toward 'hybrid' maritime security. By training coast guards in military operations, the U.S. and its partners are increasing their flexibility to respond to maritime disputes using non-navy assets, which can lower the risk of immediate escalation while maintaining a persistent security presence.
