It appears that the Safir upper stage uses two engines, probably R-27 derived, whereas the Simorgh upper stage has four such engines.

Well, so I was at the AIAA Adelaide Student Section Industry Night yesterday evening at the University of Adelaide when I got to talking with a recent PhD graduate. He mentioned that he had worked on the second stage of a launch vehicle, helping to solve a problem with its engines. I asked which launch vehicle. He was a bit cagey with his reply. He then said he got his PhD from Iran! I asked if the vehicle was Safir and he was surprised that I knew about the vehicle he had worked on! Iran had asked him to work on their missile program, but he did not want to do that. He said that he hadn't had any involvement with Simorgh.

I believe it was a vibration problem, as that is the area of his PhD research.
