ROKS Jeongjo the Great (DDG-995) is the fourth ship the of the Sejong the Great class of guided missile destroyers built for the Republic of Korea Navy (ROKN), and the first of four KDX III Batch II ships to be built. She is the fourth Aegis-built destroyer of the service and was named after the 22nd monarch of the Joseon dynasty of Korea, Jeongjo of Joseon. [1]

Background

The Sejong the Great class is the third phase of the ROKN's Korean Destroyer eXperimental (KDX) program, a substantial shipbuilding program, which is geared toward enhancing ROKN's ability to successfully defend the maritime areas around South Korea from various modes of threats, as well as becoming a blue-water navy. [2] The Batch II ships of the KDX III are based on the first three ships of the Sejong the Great class, with improved sensors and armament. [3]

Unlike the existing Sejong the Great-class Aegis destroyers, Jeongjo the Great is equipped with the newer Aegis Combat System Baseline 9.C2 ‘KII’ combined with AN/SPY-1D(V) multi-function radar antennae. [3] This will allow the Batch II ships to use the RIM-161 Standard Missile 3 and RIM-174 Standard Missile 6, in addition to the ROK Navy's current RIM-66 Standard Missile 2 missiles, from the Mark 41 Vertical Launching System. [4]

At 8,500 tons standard displacement and 10,000 tons full load, [5] the KDX-III Sejong the Great destroyers are by far the largest destroyers in the South Korean Navy, and indeed are larger than most destroyers in the navies of other countries, [6] and built slightly bulkier and heavier than Arleigh Burke-class destroyers or Atago-class destroyers to accommodate 32 more missiles. As such, some analysts believe that this class of ships is more appropriately termed a class of cruisers rather than destroyers. [7]

Construction and career

ROKS Jeongjo the Great was launched on 28 July 2022 by Hyundai Heavy Industries. [4] She was delivered to ROKN and commissioned on November 27, 2024. [8] [9]

The Incheon-class frigates, also known as the Future Frigate eXperimental or FFX during development, are coastal defense frigates of the Republic of Korea Navy. The lead ship was launched on 29 April 2011. The Incheon-class frigates will replace the aging fleet of Pohang-class corvettes and Ulsan-class frigates, and take over multi-role operations such as coast patrol, anti-submarine warfare and transport support. Later batches are planned to be specialized on anti-air and anti-submarine warfare. An improved version is being introduced as the Daegu-class frigate; this was previously known as Batch II of the Incheon class.

The Daegu class is based on the preceding Incheon class, and has otherwise been referred to as the Incheon class batch II, or FFG-II. Eight Daegu-class ships have been commissioned, with the final goal of 20–22 frigates, of all types, in the ROKN. The Daegu-class frigates were built by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries.

The Korean Next-Generation Destroyer (KDDX) is a next generation stealth guided-missile destroyer under development by Hyundai Heavy Industries for ROK Navy, to be launched after 2025. Displacement of the class is set to be about 8,000 tons, length 155 meters, breadth 18.8 meters and draft 9.5 meters. Will feature KVLS to launch Hyunmoo-3C land-attack cruise missiles and SSM-700K anti-ship missiles. At 8000 tons displacement, it will be lighter than Sejong the Great-class destroyers, but with more advanced sensors and stealth characteristics and lower operating costs. The ships will have advanced missile defense. The size of this new destroyer would be between that of the currently operating 4,200-ton KDX-II and the Aegis Destroyer KDX-III, and would be assigned to a naval task force. The total cost of developing and producing the six vessels is expected to top $6.2 billion.
