Chungmugong Yi Sun-sin class destroyers (Hangul 충무공 이순신급 구축함), also known as KDX-II class destroyers are multipurpose destroyers of the Republic of Korea Navy. The first ship of this class, ROKS Chungmugong Yi Sunshin, was launched in May 2002 and declared operational in December 2003. KDX-II class destroyer is the second phase of the Republic of Korea Navy's substantial shipbuilding program, KDX, which plans to help turn it into a blue-water navy from a coastal defence force.

[edit] 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 for a 'Korean VLA' is installed on the right. The ship's forward part is spacious enough to take a 64-cell Mk 41 VLS.
[edit] Construction
The Republic of Korea Navy originally wanted to commission 12 KDX-II class destroyers. However, due to budgetary problems, only 6 ships are currently planned to be commissioned. The ROKN wants to commission at least 3 more KDX-II class destroyers until 2020.
