The US Navy and the Republic of Korea Navy (ROKN) concluded Korean Spring Exercise, April 16, 2025.
The exercise ran from April. 7-16 off the southeastern coast of the Republic of Korea. It is part of an annual series of exercises between the US Navy and ROKN designed to increase proficiency in mine countermeasures operations between the two forces.
“Operating together in a combined environment is an outstanding opportunity for us to learn about how we each take on this complex mission set,” said Capt. Antonio L. Hyde, commodore, Mine Countermeasures Squadron (MCMRON) 7. “This exercise continues to show the region that the US and Korean navies are committed to preserving a free and open Indo-Pacific region.”
During the 10-day exercise, US Navy and ROKN units worked together to clear a route for ships through a simulated minefield using mine hunting, detection and neutralization capabilities, which included an underwater detonation of a simulated mine.
ROKN Mine Squadron 52 and MCMRON 7 commanders partnered throughout the exercise to direct mine hunting tasks for U.S. Navy and ROKN units. This training allowed US and ROK Navy participants to practice communicating and operating as a bilateral team, while learning to maximize their cumulative mine hunting capability.
"Nine days of comprehensive mine warfare exercise allowed ROK-US navies to improve operational capabilities and explore future directions for mine warfare development based on lessons learned." said Capt. Lee Taek-seon, commodore, ROK Mine Squadron 52. "We will continue to conduct practical mine warfare trainings to further strengthen our abilities to protect major ports and sea lines of communications in case of emergency."
