It is estimated to have between 200 and 300 Scud-B and Scud-C missiles, which Iran has renamed the Shahab-1 and Shahab-2. It also owns hundreds of Zelzal rockets and Fateh-110 semi-guided rockets.These systems allow Iran to threaten targets throughout the Gulf littoral, but they are not accurate enough to be decisive militarily. Iran would need at least 100 missiles armed with 500-kg conventional warheads - and potentially many more - to destroy a specific target with a moderate level of confidence.
If fired in large numbers, Iranian missiles might be able to harass or disrupt operations at large US or GCC military targets, such as airfields, naval ports or fuel depots. But such attacks are unlikely to not halt activities for a significantly long time.Iran is also unlikely to be able to improve the accuracy of its short-range missiles for at least the next five to ten years. The addition of more sophisticated inertial guidance units - or Global Positioning System (GPS) receivers - could improve accuracy by only 25 percent if properly incorporated into a Shahab or Fateh-110 missile, and then thoroughly tested.
