The four-day exercise was led by the U.S. Navy in collaboration with ROKN to focus on alliance-enhancing U.S. Navy and ROKN bilateral maritime communication tactics, anti-submarine warfare operations, air warfare operations, replenishment-at-sea, and more. CSGEX 2025 follows Nimitz-class aircraft carrier USS George Washington (CVN 73) and Carrier Strike Group (CSG) 5’s visit to Busan, South Korea. The previous CSGEX, held in June 2022, also featured CSG-5, represented by Nimitz-class aircraft carrier USS Ronald Reagan (CVN 76).

“Carrier Strike Group 5’s success during this exercise underscores the strength of our alliance and the trust that exists between the U.S. Navy and the Republic of Korea Navy,” said Rear Adm. Eric Anduze, commander of CSG-5. “Training side-by-side enhances our combined readiness and ensures that, together, we can respond decisively to maintain stability and uphold a free and open Indo-Pacific.”
