The Hyunmoo-2B is a short-range, solid-fueled ballistic missile developed and deployed by South Korea. The missile has a standard range of 500 km, but can travel up to 800 km with a reduced payload. It entered service in 2009 and remains operational.

It was developed by the state-run Agency for Defense Development (ADD) and entered service in 2009.

The Hyunmoo-2B ballistic missile is an upgraded variant of the previous version that into service with South Korea in late 2009. The missile has now a range of 500 km. The missile is propelled by solid-fueled and two-stage solid rocket motor

The Hyunmoo-2B has a length of over 12 m, diameter of 0.9 m, and launch weight of approximately 5,400 kg.3 The missile is solid-fueled and two-staged.4 It has a range of 500 km while carrying a 997 kg warhead.5 Reports also indicate that the Hyunmoo-2B can travel up to 800 km with a smaller (500 kg) warhead. The missile has a reported CEP of 30 m.6.

A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs) each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles.
