Compared to the existing Sejong the Great (7600-ton), its anti-submarine operation capability has been expanded by three times, and ballistic missile intercepting capability has been added.

The Navy announced that the new KDX-3 Batch 2, which is being built in additional, is equipped with a vertical firing system capable of operating all Standard-class missiles, SM-6 and SM-3. The vertical launch system mentioned seems to mean the BMD system. To cope with North Korea 's increasing ballistic missile threat.

The application of hybrid propulsion such as CODLAG and limited integrated mast is planned.
