ROKS Gyeongnam (FFG-819) is the second ship of the Daegu-class frigates in the Republic of Korea Navy. She is named after the place, Gyeongnam. The ship was launched in 2019 and commissioned in 2021.

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]

ROKS Gyeongnam was launched on 21 June 2019 by Daewoo Shipbuilding and commissioned on 4 January 2021.^[4][5]
