Description

The Hyunmoo-4 is a surface-to-surface ballistic missile operated by the Republic of Korea Armed Forces. Its development followed a 2017 agreement to revise missile guidelines regarding payload limitations. The system is a variant of the Hyunmoo-2C.

The missile is designed to strike hardened underground military facilities, command centers, and leadership bunkers. It is equipped with a conventional warhead. The system utilizes a payload capacity that is increased relative to earlier variants in the series to facilitate the penetration and destruction of reinforced structures. The missile is deployed via mobile launchers.

The Republic of Korea Armed Forces operates the system. Two missiles were test-fired in April 2020; one of these launches resulted in a misfire.
