Optimistic but not utopic in my opinionVery optimistic, but I doubt Russia would export the SU-57 at the time being.
Less than 6 months:
- Delivery of the first Su-30s in small number, followed by the first Su-35s
- Iran delivering TBM/SRBMs such as Qiam, Zolfaghar, F-110 family SRBMs to Russia, which will probably have a great effect on the terrain and liberate space in Iran's missile stashes to replace them with recent BMs.
- Deeper military cooperation with Russia, possible unveiling of the supersonic AShCM at the same time
Future (1-5 years):
- Delivery of 50+ Su-35s and a small number of Su-57s (<5)
- Full order delivered
- Russia help to make compatibility for all IRIAF fighters and IADS
- Compatibility with Iranian weapons
- Manufacture of parts
As 50 Su-35 is not enough for a territory like Iran:
- Standardization of the rotting MiG 9.12 to MiG-29M2 standard, same for Su-24MK to M2 standard.
- As Iran IADS would be relieved for some time, Iran focus on Kowsar and radars, also studying Russian designs and getting more experience
- Interests in the Su-75 project
- Reaching a fleet of 250+ modernized/purchased/produced fighters
- Delivery of a small number of Mi-35M/Mi-28 and Ka-52, along civilian helicopters, possible Mi-26 heavy lift helicopter
- Delivery of a small number of Pantsir and either S-350/S-400 complementing Med-range 3rd Khordad and LORAD S-300PMU2/B-373, deployment of more 3rd Khordad and deployment of Zoubin SHORAD, shuffling every layers with different systems
- Unveiling of ASAT B-373, deployment of B-373 armed with Sayyad-4B, coupled with S-300/400 as a mix
This is indeed (very) optimistic but from now i am persuated anything can happen, S-400, Yak-130, Su-30, Su-35, fleet standardization were among those that Iran wanted to purchase according to western intelligence. Time will tell.
