Daegu-class Guided Missile Frigate

The Daegu-class frigates (Hangul: 대구급 호위함, Hanja: 大邱級護衛艦) are multirole frigates of the Republic of Korea Navy. The Daegu-class is an improvement of the preceding Incheon-class frigate, and has otherwise been referred to an Incheon-class batch II, or FFX-II. Eight Daegu-class ships are planned, with the final goal of twenty to twenty-two frigates (of all types) in the ROKN. The Daegu-class vessels are to be built by Daewoo Shipbuilding & Marine Engineering (DSME).
