M-SAM
The M-SAM (Medium-range Surface-to-Air Missile; Skybolt; Korean: 천궁; Hanja: 天弓; RR: Cheongung), or KM-SAM, is a South Korean medium range surface-to-air missile (SAM) system that was developed by the Agency for Defense Development (ADD) with technical support from Almaz-Antey and Fakel, based on technology from the 9M96 missile used on S-350E and S-400 missile systems. Originally designated as Cheolmae-2 (Iron Hawk; Korean: 철매; Hanja: 鐵鷹; RR: Cheol-mae) during its development phase, the system was officially renamed Cheongung upon completion.
