The world's largest combined and joint maritime exercise, Rim of the Pacific 2026 has successfully concluded.

The biennial exercise began on June 24, bringing together 30 nations. The US DoD, in a statement said, 30 surface ships, five submarines and more than 197 aircraft participated in the exercise  under the theme "Partners: Integrated and Prepared."  

Over the course of five weeks of realistic training, participating forces enhanced interoperability, strengthened operational readiness and reinforced the partnerships that underpin  maritime security across the Pacific region. 

"No single nation can ensure security in the Pacific alone," said Navy Vice Adm. Jeff Jablon, commander of the Rimpac 2026 task force. "The global maritime environment is too large and too complex for any one country to safeguard by itself. Rimpac gives us the chance to build the trust and relationships that make us stronger long before any crisis happens." 

The exercise was conducted in three phases. During the in-port phase, participants established multinational command relationships, planned operations and strengthened partnerships through professional exchanges, cultural events and sporting competitions, it stated.

During the at-sea phase, participating forces executed complex combined and joint training, including anti-submarine warfare, maritime strikes, integrated air and missile defense, amphibious operations and logistics. The exercise concluded with a free-play scenario in which opposing forces reacted dynamically to one another to evaluate the force's combined and joint maritime capabilities. 

Throughout the exercise, participating forces executed more than 500 maritime training events, flew more than 2,400 sorties and responded to more than 5,000 scenario-based operational problems, it said.
