The Shahab-3 (; meaning "meteor-3") is a quad-exhaust liquid-propelled medium-range ballistic missile (MRBM) developed by Iran and based on the North Korean Nodong-1. The Shahab-3 has a range of ; a MRBM variant can now reach (can hit targets as far as Israel, Egypt, Romania, Bulgaria and Greece). It was tested from 1998 to 2003 and added to the military arsenal on 7 July 2003, with an official unveiling by Ayatollah Khamenei on July 20. With an accuracy of 140 m CEP, the Shahab-3 missile is primarily effective against large, soft targets (like cities). Given the Shahab-3’s payload capacity, it would likely be capable of delivering nuclear warheads. According to the IAEA, Iran in the early 2000s may have explored various fuzing, arming and firing systems to make the Shahab-3 more capable of reliably delivering a nuclear warhead.
