The South Korean Navy's Aegis destroyer Jeongjo the Great departed from a naval base on Jeju Island on Monday to join the RIMPAC exercise [1, 2].
This deployment marks a significant shift in regional military cooperation because South Korea will assume command of naval forces during the exercise for the first time [3]. The move signals an increase in the operational responsibility and leadership role of the South Korean Navy within the U.S.-led framework.
The Rim of the Pacific exercise, known as RIMPAC, is scheduled for later this month [1, 2]. The destroyer is traveling to participate in the 2026 iteration of the drills [2]. These maneuvers are designed to foster international maritime cooperation, and enhance interoperability between participating navies.
The RIMPAC drill is expected to last for five weeks [2]. By leading naval forces, South Korea demonstrates its capacity to manage complex multilateral operations in the Pacific theater [3].
The Jeongjo the Great is one of the most advanced assets in the South Korean fleet. Its participation in the 2026 exercises provides a platform for the crew to test Aegis combat systems in a high-intensity, multilateral environment [1, 2].
“South Korea will assume command of naval forces for the first time”
South Korea's transition from a participant to a commanding entity in RIMPAC reflects a strategic evolution in its defense posture. By taking a leadership role in one of the world's largest maritime exercises, Seoul is signaling its intent to play a more proactive role in Pacific security and reducing its reliance on U.S. operational command.
