Under the deal, HHI will deliver the first of three Aegis destroyers by November 2024. In May, South Korea approved plans to construct the second batch of three destroyers with a budget of around US$3.3 billion.
The KDX-III Batch II program calls for the construction of three Aegis destroyers, one to be delivered every two years from 2023. The three existing 7,600-ton KDX-III Batch I Aegis destroyers of the ROK Navy are based on the DDG 51 Arleigh Burke-class of the US Navy.
Based on the existing Sejong the Great-class the new AEGIS destroyers will feature several improvements including improved combat systems that can detect and track targets at greater distances and anti-ballistic missile capability with Raytheon’s SM-3 interceptors.
The KDX-III Batch II will be fitted with SM-2 as well and, possibly, the new SM-6 “multi-mission missile” capable of long-range Fleet Air Defense, Sea-Based Terminal defense, and Anti-Surface Warfare.
