The Donghae-class PCC (Patrol Combat Corvette) (Hangul: 동해급 초계함, Hanja: 東海級哨戒艦) is the low-end complement of the high-low mix domestic naval construction plan of the Republic of Korea Navy under the 1st Yulgok Project (1974-1986) for the Republic of Korea Armed Forces. The ship is designed for patrolling maritime border, including the Northern Limit Line, protecting the littoral zone, and combating the North Korean vessels.
