The vessel's propulsion scheme is a COmbined Diesel-eLectric-Or-Gas (CODLOG) configuration intended to maximize fuel while providing for enhanced performance. The arrangement includes 1 x Rolls-Royce MT30 gas turbine mated to 4 x MTU 12V4000 M53B marine diesels and 2 x Leonardo DRS electric motors. Collectively, the entire propulsion system is British-German-Italian in origin.
The arrangement supplies the ship with a maximum ocean-going speed of 30 knots and a range out to 4,500 nautical miles - giving the warship good "legs" in ideal conditions and plenty of range for patrolling the vast South Korean coastline.
Aboard is a complement of 140. Systems include the SPS-550K air-search 3D radar, the SPG-540K Fire Control System (FCS) radar, and the Hanwha SAQ-600K Naval Shield Integrated Combat Management System (NSICMS). Submarine-hunting is aided by the hull-mounted SQS-240K and towed SQR-250K sonar arrays. Electronic Warfare (EW) is handled through the LIG Nex 1 SLQ-200(V)K "Sonata" suite. The installed SLQ-261K is a torpedo acoustic CounterMeasure (CM) system.
In keeping with Western design methods, armament for the ship is a complementary mix of projectile- and missile-based solutions incorporating a single 5" (127mm) Mk 45 Mod 4 /L62 caliber turret deck gun over the forecastle. Close-in defense is by way of twin 20mm Phalanx Close-In Weapon Systems (CIWSs). There is a 16-cell Vertical Launching System (VLS) installed that supports Surface-to-Air Missiles (SAMs), anti-ship missiles, and land-attack cruise missiles. Beyond all this are twin triple-tubed torpedo launchers (supporting the "Blue Shark" family of torpedoes) and twin 4-cell SSM-700K "Haeseong" anti-ship missile launchers.
All told, the warship carries enough firepower to counter most any at-sea threat, whether it be from the air, on the sea, or under it. In this way, the vessel can be called upon to undertake many roles including air defense, deterrence, and direct-attack.
An extension of the warship is its single helicopter supported from the rear helipad that comes complete with a full-service hangar facility. Supported types include the Westland "Super Lynx" or AW159 utility types typically outfitted for the sub- or -ship-hunting role. Beyond this the helicopters can assist in at-sea resupply, Search & Rescue (SAR) sorties, and in Over-the-Horizon (OtH) scouting work.
