The Isfahan Missile Complex is Iran's largest missile assembly and production site. [1] 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. [2]

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. [3] 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.
