The Incheon-class frigates (Hangul: 인천급 호위함, Hanja: 仁川級護衛艦), also known as the Future Frigate eXperimental or FFX during development, are coastal defense frigates of the Republic of Korea Navy. The lead ship was launched on 29 April 2011. The Incheon-class frigates will replace the aging fleet of Pohang-class corvettes and Ulsan-class frigates, and take over multi-role operations such as coast patrol, anti-submarine warfare and transport support. Later batches are planned to be specialized on anti-air and anti-submarine warfare. An improved version is being introduced as the Daegu-class frigate; this was previously known as Batch II of the Incheon class.
