The naval development of the three East Asian countries is nicknamed "monster room" by netizens. All three countries have a strong civil shipbuilding industry and excellent electronics industry, which is enough to feed back to the military shipbuilding industry. The No. 8 of the "Daegu" class frigate , which is currently built in large quantities, was launched at the Hyundai Heavy Industries (HHI) Ulsan Shipyard two days ago. This is the last of the "Daegu" class.
On March 22, the Daegu-class frigate "Chuncheon" with hull number 827 was launched at Hyundai Heavy Industries Ulsan Shipyard, which is expected to enter service by the end of 2023. As the product of the second batch of the "Korea Test Frigate" (FFX) (FFX batchII), the first ship "Daegu" class "Daegu" (hull number 818) was launched in June 2016 at the Geoji Shipyard of Daewoo Shipbuilding and Marine Engineering Corporation (DSME) and entered service in March 2018.

However, it may be that due to the problem of subsystem integration, the second ship "Qingnan" (819), also built by Daewoo Shipbuilding, was launched in June 2019. It was three years after the first ship, and it has been 1 year this year. After that, Daewoo Shipbuilding and Hyundai Heavy Industry took turns to build this frigate with a full load displacement of 3,592 tons. The No. 3 ship "Seoul" undertaken by Hyundai Heavy Industry, the No. 4 ship " Donghai ", and the No. 7 ship "Tianan" constructed by Daewoo Shipbuilding, the No. 5 ship " Daejeon " and " Poshang " constructed by Daewoo Shipbuilding have all been launched, and both sides have undertaken to build 4 ships.

From the ship name, you will find that the "Daegu" class is to replace the 1200-ton "Posan" class light frigate and the 2000-ton "Ulsan" class frigate that the South Korean Navy had previously served and built in the 1980s and 1990s. The "Posan" class built a total of 24 ships. In addition to the "Tianan" being sunk for no reason, many have been retired or given to other countries. The South Korean Navy still has 7 ships in service, while the "Ulsan" class has built a total of 9 ships, 4 ships remain in service, and 2 ships have been replaced in reserve.

FFX series frigates, which is to replace the above 2 old frigates. Among them, the "Daegu" class is the second step in the FFX's "three-step" plan. From 2013 to 2016, the first batch of FFX's six "Incheon" frigates have been put into service. Compared with the "Daegu" class, the "Incheon" class has a slightly smaller displacement of 3,200 tons, and the power package is different. It has only point air defense rather than regional air defense capabilities, which is closer to our 056 in positioning, and the "Daegu" class can be regarded as South Korea's "054A Smithda".

Although the displacement is less than 4053 tons of 054A, the "Daegu" class inherits the tradition of "luxury" power configuration of South Korean frigate.
It is the first frigate in South Korea to adopt joint propulsion of diesel-burning and electric power. The power pack is powered by a Rolls-Royce (Royce) MT30 high-performance high-power gas turbine, 4 TTT MTU 12V 4000 M53B diesel engine and 2 Leonardo DRS motors. It can be seen that the power configuration on the Korean warship can get the best from the West, while the "Incheon" class uses relatively traditional diesel-burning alternating power, consisting of 2 US-made LM2500 gas turbine and 2 TT MTU 12V 1163 TB83 diesel engines.

in the Netherlands, the Daegu-class power has good quietness, so the ship attaches great importance to submarine combat. It also sets up the SQR-250K low-frequency towed passive sonar system (TASS) at the tail of the ship for the first time. Compared with the All-Chai-Combined Power (CODAD), the quietness and acceleration of the ship's gas turbine are excellent, which is of great significance to seize the anti-submarine position.

"Daegu" class is the first frigate in South Korea that has a missile vertical launch system (VLS).The ship is equipped with a 16-unit Korean vertical launch system (K-VLS), which may be the MK41 reverse imitation of Korean . It can launch the "Sea Bow" ship-to-air missile, "Red Shark" anti-submarine missile or "Sea Dragon" (SSM-701K) developed by LIG Nex1. Tactical ground attack cruise missile . The anti-ship weapon is 8 SSM-700K "Sea Star" anti-ship missiles. There is a US-made MK45 naval gun on the bow. There is a "intensive array" self-defense above the helicopter hangar. There are 2 sets of 3-tube K745 "Blue Shark" light anti-submarine torpedo tubes on the ship. The helicopter hangar can accommodate a super lynx or wildcat anti-submarine helicopter.

It is worth mentioning that the "Sea Bow" missile code-named K-SAAM is a very compact short-range ship-to-air missile.
It can be arranged in K-VLS in the form of "1 pit and 4 bombs", using infrared imaging and active radar dual-mode guidance, with a range of 20 kilometers, and is used to replace " Ram ", and has good killing capabilities for sea-sweeping anti-ship missiles. 8 units can load 32 "sea bows", while the other 8 units can accommodate anti-submarine or land attack cruise missiles. For a 3,600-ton frigate, the firepower is quite strong. The "sea bow" missile may be developed from the "Sky Bow" medium-range surface-to-air missile developed by South Korea from the S-350 "Warrior" obtained by South Korea from Russia.

to serve 14 "Incheon" and "Daegu" class frigates, South Korea will also build a FFX-III frigate with phased array radar , maintaining a main fleet of 24 3500-ton class frigates, and its development trends cannot be underestimated.
