Simorgh SLV > Preview > First launch > Summer-2013
This Simorgh seems like a different class launcher than the earlier Safir, which was a R-18 derivative (R-18 is the term used for missiles based on the alleged R-18 Russian design for a Scud upgrade, which was never built in Russia. Allegedly, Makayev sold the design to some 3rd world nation, which then went on to build the R-18 and sell it to other countries. R-18 class missiles have a diameter of 1.25 meters). Simorgh seems to be a copy of the Unha system, which may be based on the Burya engine (4 Scud engines operating in parallel), with a small second stage based on R-27 verniers). The North Koreans used a smaller third stage, but its not clear if Simorgh has a 3rd stage in the payload fairing.
I was told that Simorgh design is much closer to PRC design than Unha-3 family.
Are those 3D models your own work or release from official sources?
Iran is very innovative in improving the performance of the engines. The engines of the Safir-1B were already qualified for the new fuel combination UDMH/N2O4. On the qualification of the engines for the second stage of the Simorgh was also worked.

The conversion is not simple, nor would the enhancements be optimized. This seems to be more myth than fact, but I will keep an open mind of some facts are presented.
My own work ... from official informations

WHAT are the "official information" other than some pictures published on Iran space technologies day in 2010?There is NOTHING in the 3d art that is NEW or UNKNOWN from previous pictures. For example - where is the steering system for the first stage? The location of the fuel and oxidizer tanks?
Where is the launch site for this ?They would need something of the same size as the North Korean site ? I didn't know they had that.
