The Daegu-class frigate (Hangul: 대구급 호위함, Hanja: 大邱級護衛艦) is a class of guided missile frigates of the Republic of Korea Navy (ROKN). The Daegu class is based on the preceding {{sclass|Incheon|frigate|4}}, and has otherwise been referred to as the Incheon class batch II, or FFG-II. Eight Daegu-class ships have been commissioned, with the final goal of 20–22 frigates, of all types, in the ROKN.{{cite web|url=http://www.rolls-royce.com/media/press-releases/yr-2017/1605-2017-rr-to-supply-mt30-gas-turbines-to-next-three-korean-daegu-class-frigates.aspx|title=Rolls-Royce to supply MT30 Gas Turbines to next three Korean Daegu-class frigates|website=www.rolls-royce.com}} The Daegu-class frigates were built by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries.
Features
{{see also|Incheon-class frigate}}
The Daegu class is an improved variant of the {{sclass|Incheon|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, K745A1 Red Shark anti-submarine missile, and SSM-700K Haeseong tactical land attack cruise missiles.[https://thediplomat.com/2016/06/rok-navy-launches-new-warship-capable-of-hitting-targets-inside-north-korea/ ROK Navy Launches New Warship Capable of Hitting Targets Inside North Korea] - Thediplomat.com, 9 June 2016
The hull design is generally based on the Incheon class. As a part of weapon system modifications, the superstructure has been significantly changed. The hangar and a helicopter deck on the stern has been enlarged to support the operation of a 10-ton helicopter.{{cite web|url=http://www.defenseindustrydaily.com/ffx-koreas-new-frigates-05239/|title=Koreas New Coastal Frigates: the FFX Incheon Class|publisher=}}[http://navyrecognition.com/index.php/news/defence-news/2016/december-2016-navy-naval-forces-defense-industry-technology-maritime-security-global-news/4711-south-korea-orders-two-daegu-class-ffx-ii-frigates-ahead-of-schedule-to-support-shipbuilder.html South Korea Orders Two Daegu-class FFX-II Frigates Ahead of Schedule to Support Shipbuilder] - Navyrecognition.com, 21 December 2016
The Daegu class is the first Korean warship equipped with a combined diesel-electric or gas (CODLOG) propulsion system. The propulsion system of the ROKN ships have a gas turbine direct drive, and four high speed diesel generators driving two Leonardo DRS permanent magnet electric motors. The Rolls Royce MT30 turbine engine replaces the twin gas turbine layout of the Incheon-class frigates.
The Daegu class provides improved anti-submarine warfare (ASW) capability than the predecessor Incheon class. An improved ASW capability is provided by the Hanwha Systems SQS-250K towed array sonar and SQS-240K hull-mounted sonar.{{Cite web|last=GDC|date=2021-07-12|title=South Korea launches fifth FFX II Daegu-class frigate ROKS Daejeon|url=https://www.globaldefensecorp.com/2021/07/13/south-korea-launches-fifth-ffx-ii-daegu-class-frigate-daejeon/|access-date=2021-07-13|website=Global Defense Corp}}
