Propulsion is provided for through a COmbined Gas-And-Gas (COGAG) arrangement, offering a balance of performance and fuel efficiency. The system comprises 4 x General Electric LM2500 gas turbines developing 100,000 horsepower to drive 2 x Shafts astern. This provides the vessel with a top headway speed (in ideal conditions) of 30+ knots and a range out to 5,500 nautical miles (6,300 miles).
Aboard is a typical operating crew of 300 hundred with onboard stores allowing the warship to remain at sea / on station for up to thirty days. The warship carries the AN/SPY-1D(V) multi-function radar set alongside the AN/SPG-62 fire control radar. Sonar fits include the hull-mounted DSQS-21BZ-M system and the SQR-220K towed array.
At the heart of any modern guided-missile destroyer is a broad armament suite, providing solutions against virtually any at-sea threat. The suite is led by a 5" (127mm) Mk 45 Mod 4 /L62 turreted deck gun over the forecastle offering ballistics based firepower at range. Short-ranged defense is through the 30mm "Goalkeeper" Close-In Weapon System (CIWS). Missile weaponry consists of an 80-cell Mk 41 VLS supporting the SM-2 Block IIIB/V Surface-to-Air Missile (SAM) along with a 48-cell K-VLS firing off K-ASROC (Anti-Submarine ROCket) "Red Shark" missiles and/or the "Hyunmoo III" land-attack cruise missile. There are also 16 x SSM-700K Surface-to-Surface Missile (SSM) anti-ship missiles for ranged defense against surface threats and a single RAM (Rolling Airframe Missile) Block 1 CIWS unit. To counter undersea threats, the warship has 2 x Triple torpedo tubes for its store of K745 "Blue Shark" torpedoes.
As it stands (2021), ROKS Yulgok Yi I maintains an active presence in the South Korean fleet and has regularly participated in the joint RIMPAC exercises with the United States and other Asia-Pacific allies.
