The missile system is actually based on the old U.S. designed Hawk missile system.  The Iranians call their updated version ‘Shahin’ (not to be confused with ‘Shaheen’ which is a different missile system).

Most of the upgrades are related to search and track capabilities.  They say it’s a mid-altitude missile, one source saying its range is 15 miles (maybe they meant 15 kilometers?).  I can’t be sure of the performance claims, simply because the Iranian media gives wildly different data.  One source said the missile could reach 150 kilometers (93 miles), that’s the Thermosphere, man!
