On September 8, 2021, the 6th Daegu-class frigate was launched at the Okpo shipyard, the Pohang (FFG-825).
South Korea has awarded contracts for all eight ships in the class, which are being delivered by DSME and Hyundai Heavy Industries. The Daegu-class provides improved anti-submarine warfare capability than the predecessor Incheon-class frigate. The hull design is generally based on the one of the Incheon-class.
Daegu-class frigates are quite compact in size. The standard displacement is 2,800 tons, and full load of 3,593 tons. She is 122m long (400 ft), the beam is 14m (46 ft) and the draft is 34m (13 ft).
According to the manufacturer, the survivability of the Daegu class has been maximized because it has a stealth design. Inheriting the Incheon-class hull design, however, the weapon system and superstructure were significantly changed on the Daegu-class frigates.
The hangar and a hellicopter deck on stern has been enlarged to support the operation of a 10-ton helicopter. Supported types include the Westland Super Lynx or AW159 utility types, serve as anti-submarine or anti-surface ship roles. Helicopters can assist in sea resupply, Search & Rescue missions, and in Over-the-Horizon reconnaissance work.
Daegu-class is the first South Korean warship to be fitted with DRS Hybrid Electric Drive system, coupled with Rolls-Royce MT-30 gas turbine engine for Combined diesel-electric or gas integrated full-electric propulsion.
This combination helps to maximize fuel savings while providing enhanced performance. The ship can reach a top speed of 30 knots, a cruise speed of 18 knots, and a range of 4,500 nmi. Korean frigates can accommodate 140 sailors.
In terms of engine technology and acoustic reduction technology, this makes the class one of the most advanced and ‘reduced accoustic signature’ ASW frigates among western navies.
ROKS Pohang FFG-825 and her sisters are equipped with a 16-cell Korean vertical launching system, to deploy K-SAAM – Korean Surface to Air Anti Missile, Hong Sang Eo anti-submarine missile, and Haeryong SSM-701K Sea Dragon tactical land attack cruise missiles. They also carry torpedo launchers for anti-submarine warfare and eight SSM-700K Haeseong anti-ship missiles. All these missile systems are designed and produced by local company LIG Nex1. The gun systems consists in a Mk 45 mod 4 naval gun system and a Phalanx Block 1B CIWS.
