The three armed forces also practiced the procedures of shipwreck rescue and first aid transfer through joint maritime search and rescue exercises.
This is the first anti-submarine joint exercise conducted by the United States, Japan, and South Korea after six months since September 2022. It is also the fourth time that the three parties have conducted a joint exercise on the high seas near the Korean Peninsula since the Yoon Seok-yue government of South Korea came to power.
The USS Nimitz aircraft carrier (CVN-68), the Arleigh Burke-class guided-missile destroyers USS Decatur (DDG 73) and USS Wayne Meyer (DDG 108) participated in the joint exercise, and the Japanese Maritime Self-Defense Force’s Sea Fog USS (DD-158), as well as South Korea’s Aegis destroyer Yulgok Lee Er (DDG-992), Daejoyoung (DDH-977), Korean destroyer Choi Young (DDH-981) and comprehensive supply ship Soyang ( AOE-51).

The Nimitz Carrier Strike Group conducts regular operations with the U.S. Seventh Fleet, the largest forward-deployed fleet of the U.S. Navy, regularly interacting and operating with allies and partners to maintain a free and open Indo-Pacific.
North Korea has made frequent military moves in recent days. At the end of March, it carried out successive tests of new underwater nuclear attack unmanned boats, launched multiple strategic cruise missiles simulating nuclear warheads, announced new miniature nuclear warheads, and claimed to produce more weapon-grade nuclear materials to further expand its nuclear arsenal.
On April 3, when asked about the situation on the Korean Peninsula at a regular press conference, Chinese Foreign Ministry spokesperson Mao Ning said that the US-South Korea military exercises and the US-Japan-South Korea joint exercises followed one after another, and the US nuclear-powered aircraft carrier was cruising around the peninsula.
