Incheon-class

The Incheon-class frigates were developed as part of the Future Frigate eXperimental programme to modernise the Republic of Korea Navy's coastal defence force. They replaced older Ulsan-class frigates and Pohang-class corvettes with more capable ships suited to patrol, escort, anti-surface, and limited anti-submarine missions.

Incheon-class ships are not as large as Korea's destroyers, but they provide a modern frigate layer for patrol and escort work. Their combat systems and sensors improve reaction time and situational awareness compared with earlier coastal combatants. The class became the first batch in a broader FFX frigate evolution.

For HiWars, Incheon-class frigates help explain how navies modernise the middle of the fleet. Not every mission requires an Aegis destroyer; frigates provide persistent coverage, escort capacity, and maritime security presence at lower cost.
