The Incheon-class frigates (Korean: 인천급 호위함, Hanja: 仁川級護衛艦), also known as the Future Frigate eXperimental or FFX during development, and latterly, the FFX-I, or FFG-I, 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, FFX-II.
