F-4-5-14, SU-24-25, Saeqeh-1-2 combination is not weak but old and strong.
We will have a big shift in our air superiority within the upcoming two years. I mean after developing heavy turbojet engines. At the same time Iran is able to raise the Titanium percentage in it's super alloys, also can install AESA radars due to Iran's long history of activity in the radar productions, then only two years is remaining for Iran's muscling up in the sky. If we consider SU-30 joint production in Iran is not possible And i hope so, Russia withdraws from that proposal, then Iran will get forced to develop it's home made fighters.
