The Gwanggaeto the Great-class destroyers (Korean: 광개토대왕급 구축함; Hanja: 廣開土大王級 驅逐艦), often called KDX-I, are destroyers, but are classified by some as frigates, operated by the Republic of Korea Navy. It was the first phase of ROKN's KDX program, in moving the ROK Navy from a coastal defence force to a blue-water navy.
