## Development

[edit]

Main article: Daegu-class frigate

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 that 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]

## Construction and career

[edit]

ROKS Daejeon was launched on 3 May 2021 by Daewoo Shipbuilding.[4]
