KDX-II modernisation to enhance South Korea’s combat readiness

South Korea’s Defense Acquisition Program Administration (DAPA) has launched a significant performance improvement program (PIP) for its Chungmugong Yi Sun-sin-class destroyers (KDX-II), aiming to modernise critical systems and enhance combat readiness. The KDX-II upgrade underscores South Korea’s focus on leveraging indigenous technologies to maintain a modern and effective naval fleet amid rising regional maritime tensions, according to GlobalData, a data and analytics company. GlobalData’s latest Fleet Size dashboard reveals that approximately 23% of the Republic of Korea Navy’s fleet comprises vessels with an average age exceeding 20 years. The KDX-II upgrade program is part of a broader effort to modernize South Korea’s naval fleet, ensuring it remains capable of countering emerging threats from adversarial forces. Harpreet Sidhu, Aerospace and Defense Analyst at GlobalData, comments: “The replacement of outdated combat systems with advanced domestic alternatives is particularly significant, as it aligns with South Korea’s ambition to establish itself as a regional naval manufacturing powerhouse. “With North Korea’s increasingly complex undersea threats and growing range of ballistic missiles arsenal, the integration of advanced sonar and missile systems improves anti-submarine and air-defence capabilities of the destroyer fleet. Additionally, this upgrade addresses vulnerabilities that were made public during high-profile exercises such as the RIMPAC 2022, where weaknesses around operational readiness owing to system malfunctions were brought to light.” A key point to note in the PIP program is the simultaneous integration of advanced domestic technologies and selective reliance on critical components like the MK 99 fire-control system procured via Foreign Military Sales (FMS). This hybrid approach supplements local innovations by utilising relationships with global OEMs, thus reflecting a more nuanced strategy. Sidhu concludes: “While the current program does not include a radar upgrade, it leaves room for future enhancements such as integrating advanced AESA radar systems like SPS-560K or AN/SPY-7. This multi-phased strategy demonstrates South Korea’s intention to develop capabilities of its naval platforms in line with technological breakthroughs it achieves over the future years, guaranteeing the fleet’s long-term viability. The KDX-II upgrades, in essence, are not just about modernising older naval platforms, but are a cornerstone of South Korea’s broader strategy to assert its presence in the increasingly contested waters of the Indo-Pacific.” For Editorial Inquiries Contact: Editor Kym Bergmann at [email protected] For Advertising Inquiries Contact: Group Sales Director Simon Hadfield at [email protected]
