Eight Daegu-class ships have been commissioned, with the final goal of 20–22 frigates, of all types, in the ROKN.

[1] The Daegu-class frigates were built by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries.

Modifications to the Incheon class include a TB-250K towed array sonar system and a 16-cell Korean Vertical Launching System (K-VLS), that is able to deploy the K-SAAM, K745A1 Red Shark anti-submarine missile, and SSM-700K Haeseong tactical land attack cruise missiles.

[3][4] The Daegu class is the first Korean warship equipped with a combined diesel-electric or gas (CODLOG) propulsion system.

[5] On 16 April 2024, Hyundai Heavy Industries signed a ₩640.6 billion ($463.7 million) deal with SIMA, Peru's state-run shipyard, to build four naval vessels, including a 3,400-ton frigate based on the Daegu class.
