Development

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

ROKS Seoul was launched on 11 November 2019 by Hyundai Heavy Industries and expected to be commissioned in 2021. [4]
