ROKS Chungmugong Yi Sun-sin (DDH-975) is a Chungmugong Yi Sun-sin-class destroyer in the Republic of Korea Navy. She is named after the ancient Korean admiral Yi Sun-sin with his posthumous name, Chungmugong, literally “Lord of Loyal Valor”.
The KDX-II is part of a much larger build up program aimed at turning the ROKN into a blue-water navy. It is said to be the first stealthy major combatant in the ROKN and was designed to significantly increase the ROKN's capabilities.
