Po Hang (Flight IV)

The Pohang-class PCC (Patrol Combat Corvette) 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. It was originally planned as a Batch II production of Donghae-class corvette, but many changes on overall design, notably applying the hull design of Ulsan-class frigate, reclassified the ship to its own class. The ship is designed for patrolling maritime border, including the Northern Limit Line, protecting the littoral zone, and combating the North Korean vessels. Since 1984, a total of 24 Pohang-class corvettes were commissioned in the Republic of Korea Navy. The decommission of the class started in 2009, and is being replaced with series of FFX program. As of December 2025, 2 remain in service in the ROKN, and 8 were transferred to other navies.
