Development

But the decommissioning of the Gearing-class destroyers and the aging fleet of Ulsan-class frigates, the plan was revived as the Future Frigate eXperimental, also known as FFX in the early 2000s.

10 ships were launched and commissioned from 1980 to 1993. They have 3 different variants which consists of Flight I, Flight II and Flight III.^[1]
