The Shahab-1 was the foundation of the short-range Iranian missile program. During the Iran–Iraq War, Iran purchased R-17 Elbrus missiles from Libya, Syria and North Korea (Hwasong-5). It is a close copy of Hwasong-5 (R-17).
Iran began making the Shahab-1 sometime between 1985 and 1988. Iran's Shahab-1 is a short-range ballistic missile derived from the Scud-B, and has a maximum range of 300 km (185 miles).
Iran employed Shahab 1s extensively during the 1990s and early 2000s against Mujahidin-e Khalq Organization (MKO) camps in Iraq.
