KDX-III

IOC: 2008
Total Production: 3
Total Program's Cost: KRW3.1 trillion

Also Known As: DDH-III Sejongdaewang

Origin:South Korea

Contractor/s: Doosan Infracore, Hyundai Heavy Industries, Samsung Techwin

Description: The KDX-3 class ships are being designed by Hyundai Heavy Industries as the Korean counterpart to proven American DDG-51 class destroyers. These ships will feature the AEGIS weapon system with the AN/SPY-1D multi-function radar antennas. They will perform blue water missions with improved survivability over current and planned ships operated by the Korean Navy.

The number of MK41 cells estimated for the KDX-3 destroyer could be as high as 90. Standard SM-2, ESSM and Harpoon missiles are envisaged as the backbone of KDX-3 destroyers' weaponry but it has not been confirmed yet.

In October 2004, the Republic of Korea Navy ordered three RAM weapon systems for the KDX-III class destroyers. These ships will be the world's first combining proven AEGIS and RAM. South Korea intends to procure up to three KDX-3 destroyers, which are expected to achieve operational capability beyond 2010.

On November 15, 2004, General Electric announced that the LM2500 gas turbine was selected to power KDX-III destroyers with a firm order on 12 turbines. Samsung Techwin of South Korea is the propulsion system contract for this destroyer program. Four LM2500 gas turbines will be provided to each destroyer yielding 120,000-shp output altogether.
