Established in 1971, the state-owned Scientific Studies and Research Center (SSRC) oversees Syria's facilities to develop unconventional weapons and their delivery systems. [1] Specifically with respect to the missile program, the SSRC controls the missile production facilities in Homs, Hama, Al-Safir and Aleppo.
