The Qiam reaching 1000 km is quite the surprise!
Indeed, a fantastic upgrade for a mobile missile with a separating warhead and CEP <50m which reaches very high terminal velocity and can be mass produced very cheaply in the hundreds (as it already is).
Compared to the solid fuel Fateh family (Dezful MRBM would be direct equivalent), it is larger and has longer preparation time (although 20 minutes is fast too), but Qiam follows a fully ballistic trajectory (compared to quasi-ballistic Dezful) and impacts with far greater speed/power.
For me, the precision-guided MaRV Emad MRBM with the new 1000kg warhead (to 1750km range) is equally impressive. A big upgrade in terms of payload for the Shahab-derived Emad class missiles (usually 600-700kg). Israel is 1000-1200km from Iran's borders, allowing an even greater payload if used at such a range, 30-40% below its maximum range. The exo-atmospheric manoeuvrable warhead is the icing on the cake and can be retrofitted to hundreds of Emad-class MRBMs in storage.
