The Isfahan Missile Complex is Iran's largest missile assembly and production site.  Built with North Korean and Chinese assistance in the late 1980s, the facility manufactures solid and liquid propellants, missile components, and assembles Shahab and Chinese HY-2 Silkworm and M-Class missiles. 
A 2001 report alluded to two research and development facilities near Isfahan and Tehran where scientists were working with Russian SS-4 missile technology, which Iran has used to develop the Shahab-4 system.  While Tehran asserts the Shahab-4 is exclusively designed to serve as a satellite-launch vehicle, many Western experts allege that Iran developed the technology to serve as a long-range weapons delivery capability.
