Description

The KDX-3 class ships were designed by Hyundai Heavy Industries as the Republic of Korea counterpart to proven US Navy's DDG-51 class destroyers. These ships wfeature the AEGIS Baseline 7 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 KDX-3 destroyers are equipped with a 48-cell vertical launching system (VLS) developed in South Korea. Standard SM-2, ESSM and Harpoon missiles are envisaged as the backbone of KDX-3 destroyers' weaponry but it has not been confirmed yet. The Republic of Korea Navy (RoKN) early plans called for the procurement of three ships but the program was expanded to six destroyers to be commissioned by 2020. In May 2019, the RoKN approved the procurement of another three destroyers by 2030. 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.
