Development

Main article: Daegu-class frigate

The Daegu class is an improved variant of the Incheon-class frigate. 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, Hong Sang Eo anti-submarine missile, and Haeryong tactical land attack cruise missiles.^[1]

The hull design is generally based on the one of the Incheon class. However, as a part of weapon system modifications, the superstructure has been significantly changed. The hangar and a helicopter deck on stern has been enlarged to support the operation of a 10-ton helicopter.^[2][3]
