IRAN'S SHIHAB-3 MISSILE
The1300 Km Shihab (Comet) 3 IRBM achieved operational status with the Iranian Revolutionary Guard Air Force in July 2003 . It is believed that by now Iran possesses about 20 missiles of this type, which can reach Israel as well as US military targets in the Middle East
The missile's range and payload conforms well to Iran's nuclear ambitions.
The ancestry of the Shihab 3 is the North Korean missile program, which relied heavily on Soviet/Russian technology transfer.
