ROKS Sejong the Great (DDG-991) is the lead ship of her class of guided missile destroyer built for the Republic of Korea Navy. She was the first Aegis-built destroyer of the service and was named after the fourth king of the Joseon dynasty of Korea, Sejong the Great.[1]

Background

[edit]

The ship features the Aegis Combat System (Baseline 7 Phase 1) combined with AN/SPY-1D multi-function radar antennae.[1]

The Sejong the Great class is the third phase of the South Korean navy'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]

At 8,500 tons standard displacement and 10,000 tons full load,[3] the KDX-III Sejong the Great destroyers are the largest destroyers in the South Korean Navy, and are larger than most destroyers of other navies.[4] 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.[5]

Construction and career

[edit]

ROKS Sejong the Great was launched on 25 May 2007 by Hyundai Heavy Industries. She was commissioned into the ROK Navy on 22 December 2008.

RIMPAC Exercise

[edit]

Republic of Korea Navy (ROKN) has actively participated in the recent iterations of the RIMPAC, which is a unique training opportunity that helps participants foster and sustain cooperative relationships. On 23 June 2010, ROKS Sejong the Great participated in RIMPAC 2010.[6]

She again participated in 2016 RIMPAC exercises along with ROKS Kang Gam-chan, and submarine ROKS Lee Eokgi of the ROKN.

Sejong the Great again participated in RIMPAC 2022.[7]
