The USS Carl Vinson (CVN 70) UNIT/s, ROK UNIT/s, JMSDF UNIT/s joined the drills, which were held between 17-20 March 2025.
The drills were aimed at advancing interoperability and readiness across various warfare areas.
The exercise encompassed a range of activities including group sails, advanced maritime communications, maritime interdiction operations training, air combat drills, and staff exchanges.
These drills are part of ongoing efforts to strengthen combined capabilities and improve integration within the Joint Force.
In a press release, US Indo-Pacific Command stated: “Enhancing trilateral security cooperation with the ROKN and JMSDF ensures our militaries and self-defence forces can operate together against any threat.”
The training exercises build upon the regular trilateral cooperation, including the January 2025 trilateral bomber escort flights.
In January, the CSG-1 led by USS Carl Vinson teamed up with the JMSDF and the ROKN for a trilateral maritime exercise.
The USS Carl Vinson, a Nimitz-class nuclear-powered aircraft carrier, is based in San Diego, California, and was commissioned in 1982.
The USS Carl Vinson returned to its homeport at Naval Air Station North Island on 23 February after a four-month deployment in the Western Pacific.
The recent trilateral exercise also follows the November 2024 iteration of Freedom Edge, continuing the enhancement of doctrine, tactics, techniques, and procedures among the allied forces.
These trilateral naval exercises are conducted in accordance with international law, ensuring the safety of navigation and respecting the rights and interests of other states.
