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

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

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

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]
