[edit on Wikidata]

The Shahab-4 (Persian: شهاب-۴, meaning "Meteor-4") (a.k.a. IRIS) was an unbuilt Iranian rocket, derived from the Shahab-3 medium-range ballistic missile. According to Iran it was intended to be a space launch vehicle,^[1] but according to Western observers it was intended to be part of a nuclear-capable ballistic missile.^[2]

History

The IRIS/Shahab-4 project was initiated in 1988 but according to some sources, it never went beyond the drawing board. The design heritage of the IRIS was later incorporated into the Safir.^[3]

In 1997, an American satellite captured evidence of a Shahab-4 test facility in Parchin.

In 1999, it was suspected that the Shahab-4 was largely derived from NPO Yuzhnoye's R-12 Dvina, which in its single-stage variant had a maximum range of 2,000km and a circle of equal probability of 2,400km.^[2] The dual-stage R-12 Dvina was capable to lift payloads into orbit.
