Great, thanks.Thanks for the insightful (as always) contribution. Just a little observation, when I spoke of the speculative nature of discussions, I meant Iran's overall approach to the air force, what it plans to do in future as well as the role of projects such as the Yasin trainer aircraft. But I do not doubt general Bagheri's word when he stated that orders for weapons were indeed placed with Russia after the lifting of the arms embargo, citing fighter jets, trainers and helicopters in particular. Moreover Moscow did not deny, so to me this is factual now despite all the follow up questions it raises.
I still don't see (searching sources) an exact match specifically indicating WHICH aircraft type, do you have sources for this at all? Did Bagheri actually say ... SU35 or SU30 ? tnx
