Recently, North Korea has developed a new land-mobile IRBM –called the Musudan by the United States. The Musudan is a single-stage missile and may have a range of up to 4,000 km with a 500 kg payload. The Musudan is derived from the SS-N-6 submarine-launched ballistic missile (SLBM) and represents a substantial advance in North Korea’s liquid propellant technology, as the SS-N-6 had a much more advanced engine and used more energetic propellants — unsymmetrical dimethylhydrazine (UDMH) and nitrogen tetroxide (N204) — than those used in Scud-type missiles. Development of the Musudan with this more advanced propulsion technology allows North Korea to build even longer-range missiles — or shorter range missiles with greater payload capacity — than would be possible using Scud-type technology
