The monopoly of the regular armed forces over domestic arms production and repair industries ended in 1983 when the SDC authorized the Pasdaran to establish its own military industries. This new policy was in line with the Pasdaran's growing political and military weight. Beginning in 1984, the first Pasdaran armaments factory manufactured 120mm mortars, antipersonnel grenades, various antichemical-warfare equipment, antitank rockets, and rocket-propelled grenades.
Prior to 1989 the ballistic missiles program was responsibility of the missile unit Wakhid-e-Mashachekh of the Revolutionary Guards. In 1989, elements of the Ministry of Defense and the Guards merged to form the Ministry of the Armed Forces Logistics (MODAFL), and their production facilities were merged into the Defense Industry Organization (DIO).
