Partially
designed by the South Korean Ministry of National Defense, built by
Hyundai Heavy Industries and Daewoo Shipbuilding & Marine Engineering,
the Sejong the Great class Destroyers are the largest surface combatants
in the Republic of Korea Navy. The 3 vessels of the class were built
as part of the KDX-III project to strengthen ROK Navy defense against
North Korea and other emerging threats as well as provide the ROK Navy
with true blue water, ocean going capabilities. The class revolves around the Lockheed Martin AEGIS system. Aegis Weapon System is the combination of a radar and weapon system capable of simultaneous warfare against air, ballistic missile, surface. The Aegis Weapon System is a seamlessly integrated radar and missile system capable of simultaneous operation defending against advanced air, surface and subsurface threats. A key component of the Aegis Weapon System is the SPY-1 multi-function phased array radar. It is one of the world’s most advanced and versatile maritime radar. The Korean Aegis destroyer KDX-III Project is also fitted with Huneed Technologies' Data Link Processor System (DLPS). The DLPS connects Korean Aegis destroyer KDX-III to the existing Korean Naval Tactical Data System (KNTDS) allowing the smooth flow of various data and information, and will process in real-time all the data/information required during combat. KDX-III is additionally equipped with the Samsung Thales Naval Shield Integrated Combat Management System, apart from Aegis, to connect many non-American weapons and subsystems that are present on KDX-III. |
