The ROKS Gyeongnam is a Daegu-class guided missile frigate built from the South Korean Navy by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries. The ship was launched in June 2019 and must be commissioned in early 2021. 

South Korea has ordered a total of 8 Daegu-class frigates that are built by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries.

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.

The hull design is generally based on the Incheon-class, also known as the Future Frigate eXperimental or FFX during development. 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.

The Daegu-class frigate is powered by a combined diesel-electric or gas (CODLOG) propulsion system including one Rolls-Royce MT30 gas turbine, four MTU 12V 4000 M53B diesel engine, and two Leonardo DRS electric motors. She can reach a top speed of 30 knots (56 km/h; 35 mph) with a maximum cruising range of 4,500 nautical miles (8,000 km). The ship has a crew of 140 sailors.

The Daegu-class frigate is armed with one 5 inch (127 mm)/L62 caliber Mk 45 Mod 4 naval gun, one 20 mm Phalanx CIWS (Close-In Weapon System), two triple torpedo tubes for K745 Blue Shark torpedo, eight SSM-700K Haeseong Anti-ship Missile and 16-cell K-VLS (Vertical Launching System) able to launch Haegung K-SAAM surface-to-air missile, Haeryong VL-Tactical anti-ship cruise Missiles and K-ASROC Red Shark anti-submarine missile.
