Khayal Moazzin is a highly credible journalist and often reports on behind the curtain transcaucasian politics between Iran and Russia or Iranian matters with Turkey.
My take:
- BT's report of actual order including 12 X SU-30SM/SM (Flanker-H) is true. He said that IRIAF plans to use them as trainers for SU-35S fleet. Now Khayal is repeating the same thing about SU-30SM along with SU-35S. They are dual seaters and their weapon suite matches with SU-35S, they can wear Khibiny ECM and fire R-37. Makes senses as multirole fighters but also trainers.
- Russia can probably deliver 24 airframes at best for now but cant produce SU-35S or SU-30SM for Iran (BT reported order of 68 SU-35S, 12 SU-30SM, 12 x YAK-130) since their own needs are immense right now. So there is a good possibility that licensed CKD production like that of SU-30MKI (India) can start in Iran. Someone on twitter was saying that Russia doing this will benefit from it in future because now they can have not one but two production sources of Flankers if a production line starts in Iran. They can barely produce 10-12 airframes a year for now.
- If someone noticed, IAIO production facilities are being expanded at fast pace in recent times.
