AT SEA –
The U.S. and Republic of Korea (ROK) navies and the Japan Maritime Self-Defense Force (JMSDF) conducted a trilateral naval exercise, 17-20 March, 2025.
Carrier Strike Group (CSG) 1, USS Carl Vinson (CVN 70), UNIT/s, ROK UNIT/s, JMSDF UNIT/s participated in the multi-day, trilateral exercise, advancing interoperability and readiness across multiple warfare areas.
The multi-domain exercise included group sails, advanced maritime communications, maritime interdiction operations training, air combat drills, staff exchanges and other integration, and serves to further strengthen the combined capabilities of the participating navies. Enhancing trilateral security cooperation with the ROKN and JMSDF ensures our militaries and self-defense forces can operate together against any threat.
This builds upon the regular, increasingly complex trilateral cooperation of the three nations, including the January 2025 trilateral bomber escort flights, as the three nations continue integration across the Joint Force. The last trilateral naval exercise between the U.S., ROK and Japan was conducted in November 2024 during the second iteration of Freedom Edge.
This current activity builds on previous exercises like Freedom Edge and our continuing operations together, advancing doctrine as well as tactics, techniques and procedures among our combined forces.
Trilateral naval exercises are conducted in a manner that is consistent with international law and with due regard to the safety of navigation and the rights and interests of other states.
