ULSAN — The Navy launched its newest Aegis-equipped destroyer, the Dasan Jeong Yakyong (DDG-996), at HD Hyundai Heavy Industries in Ulsan on Wednesday, marking another step in Korea’s drive to strengthen its maritime defenses. The vessel, the second in the KDX-III Batch-II program after the ROKS Jeongjo the Great, is expected to play a key role in the Navy’s three-axis system, aimed at deterring missile threats.

Named after Joseon Dynasty scholar Jeong Yak-yong (1762-1836), who is better known by his pen name Dasan, the destroyer continues the Navy’s tradition of honoring individuals who are remembered for their service to the nation. Officials said the name also reflects the values of innovation and public duty associated with Dasan’s legacy.

Measuring 170 meters in length and 21 meters in width, with a displacement of 8,200 tons, the vessel is larger than the earlier Sejong the Great-class destroyers. Its stealth design has been refined to minimize radar visibility. Outfitted with the latest Aegis combat system, it can track ballistic missiles more accurately. Future upgrades will enable it to carry ship-to-ground ballistic missiles and long-range interceptors, giving it the flexibility to conduct both long-range strike missions and missile defense operations.

It is also armed with a domestically developed integrated sonar system that enhances its ability to detect submarines and torpedoes. The ship can launch both long-range and lightweight anti-submarine torpedoes, and will carry MH-60R Seahawk helicopters to increase its operational range in undersea missions. Its propulsion system combines four gas turbines with two hybrid electric drives, cutting fuel use during cruising and reducing underwater noise for improved survivability.

Around 400 people attended the launch ceremony, including Defense Minister Ahn Gyu-back, Chief of Naval Operations Adm. Kang Dong-gil and senior officials from the Defense Acquisition Program Administration (DAPA) and the defense industry. The program included a progress report, official naming ceremony, commendations and a congratulatory address. Ahn’s wife, Shim Hye-jeong, performed the traditional ribbon-cutting ceremony to release the ship into the water, followed by the breaking of a champagne bottle against the hull to wish the vessel safe voyages.

Bang Geuk-cheol, head of DAPA’s capability enhancement office, said that the destroyer “is designed to handle a wide range of threats and will play a leading role in protecting national security and maritime sovereignty.”

Rear Adm. Kim Tae-hoon, director of naval planning, described it as “a vital shield at sea and a core asset for the fleet.”

The Dasan Jeong Yakyong will undergo sea trials before joining the Navy in late 2026, when it is scheduled to be deployed with the Mobile Fleet Command.
