The state-of-the-art Cheongung (M-SAM) II is an upgraded version of Cheongung(M-SAM) developed to secure lower tier ballistic missile defense capabilities.

Cheongung (M-SAM) II possesses unparalleled deployability and operability. The system is known to have an unmatched precision rate with hit-to-kill capabilities (precision-guided missile), exceptional maneuverability, and a world-class kill probability with omnidirectional coverage achieved by the employment of vertical launch. The Cheongung II is equipped with both high-performance side-thrust-engines, which significantly reduces the “miss distance”, and lethality enhancers which help increase lethality against "difficult-to-aim" targets such as ballistic targets.
