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.{{Cite web|title=Sejong the Great Class / KDX-III Class Destroyer|url=https://www.naval-technology.com/projects/sejongthegreatclassd/|access-date=2020-08-07|website=Naval Technology|language=en-GB}}

Background

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

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.{{Cite web|url=https://www.navyrecognition.com/index.php/132-republic-of-korea-navy-vessels-ships-and-equipment/rok-navy-frigates-a-destroyers/844-sejong-the-great-sejongdaewang-kdx-iii-class-aegis-destroyer-republic-of-korea-rok-navy-yulgok-yi-i-seoae-yu-seong-ryong-hyundai-heavy-industries-hhi-dsme-datasheet-pictures-photos-video-specifications.html|access-date=2020-08-07|website=navyrecognition.com|title=Sejong the Great Sejongdaewang KDX-III Class AEGIS Destroyer Republic of Korea ROK Navy 세종대왕급 구축함 Yulgok Yi I Seoae Yu Seong-ryong Hyundai Heavy Industries HHI DSME 대한민국 해군 datasheet pictures photos video specifications}}

As such, some analysts believe that this class of ships is more appropriately termed a class of cruisers rather than destroyers.{{Cite web |title=Sejong the Great class - Guided missile destroyer |url=http://www.military-today.com/navy/sejong_the_great_class.htm |archive-url=https://web.archive.org/web/20230326061714/http://www.military-today.com/navy/sejong_the_great_class.htm |archive-date=2023-03-26 |url-status=usurped}}
