In 1979, South Korea agreed to ballistic missile guidelines, limiting the country’s ballistic missile development and possession to 180 km in range. In 2001, United States officials agreed to extend the range limit to 300 km, which only applied to high-velocity, free flight ballistic missiles, excluding slower, surface-skimming cruise weapons. South Korea developed an unmanned aerial vehicle (UAV) and cruise missile called Hyunmoo-3. The UAV would not have any limitation in range while the cruise missile’s range was 1500 kilometers (930 miles). South Korea's missile ranges were less than North Korea’s missiles such as Rodong (1300 kilometer-ranged ballistic missile) and Taepodong-2 (6000 kilometer-ranged intercontinental ballistic missile).
