Chungmugong Yi Sun-shin class destroyers (Hangul: 충무공 이순신급 구축함) are multipurpose destroyers of the Republic of Korea Navy. The lead ship of this class, ROKS Chungmugong Yi Sunshin, was launched in May 2002 and commissioned in December 2003. Chungmugong Yi Sun-shin class destroyers were the second class of ships to be produced in the Republic of Korea Navy's destroyer mass-production program named Korean Destroyer eXperimental, which paved the way for the navy to become a blue-water navy. Six ships were launched by Hyundai Heavy Industries and Daewoo Shipbuilding & Marine Engineering in four years.

Weapon Systems

The ship has a 32-cell strike-length Mk 41 VLS for SM-2 Block IIIA area-air defence missiles, one 21-round RAM inner-layer defence missile launcher, one 30 mm Goalkeeper close-in weapon system, one Mk 45 Mod 4 127 mm gun, eight Harpoon anti-ship missiles and two triple 324 mm anti-submarine torpedo tubes.

Electronics suite includes one Raytheon AN/SPS-49(V)5 2D long-range radar (LRR), one Thales Nederland MW08 3D target indication radar (TIR), two Thales Nederland STIR240 fire-control radars with OT-134A Continuous Wave Illumination (CWI) transmitters, an SLQ-200(V)K SONATA electronic warfare system and a KDCOM-II combat management system which is derived from the Royal Navy Type 23 frigate's SSCS combat management system. BAE Systems WDS Mk 14 originally developed for the US Navy's New Threat Upgrade evaluates threats, prioritizes them, and engages them in order with SM-2.

On the 4th unit, ROKS Wang Geon, the 32-cell Mk 41 VLS is moved to the left and an indigenous VLS named K-VLS is installed on the right. The ship's forward part is spacious enough to take a 64-cell Mk 41 VLS.
