What are IRIAF Plans to replace F-1/F-4/F-7/F-5 as F-4 is atleast 34 Years old in IRAF, F-7 26 Years old and F-5 38-42 Years old And F-1 Mirages has spares-engines problems and almost nill weapons.
Should Iran NOT pursue for a single unified Fleet a common platform compatible and maintainable from point of view of engineering ground crew, OR would IRIAF be flying them until "AMCA" is certified for production would it be cost effective solution to replace estimated 72-120 [no credible information regarding numbers operational] F-1/F-4/F-7/F-5 Fleet.
A country under severe sanction would not 3-4 Types be better operational rather 7-10 Types which in itself is costly and hassle.
Any Iranian member with good information and if any good sources as to what Iran is planning regarding phasing out and introducing AFAIK, Iran is developing couple of platforms explaining that they would not be fully introduced as these are examples and tests pre their 4.5/5 Gen [reference HESA Saeqeh 20-24 numbers, HESA Azarakhsh 11 numbers]
