Abandon. the useless Kowsar F-5 project that we never heard of since 2018 eating money for nothing
Demolish the blind Mirages and the F-7Ns and use the scraps for other projects or civilian projects
Ask Russia for Saddam rotting MiG-29 9.12 fleet standard to MiG29M2
Buy MiG-31 to cover more space and act quickly and efficiently
Ask China to buy J-16 to complement Su-35/MiG-31/MiG-29M2
Ask for R-37M instead of the export R-77, try Fakour
Fit Iranian atg weapons on these
Ask Russia to make something to communicate between all aircrafts, if they don't, ask China, if this is not possible, demolish the uncompatible aircrafts
Study the new technologies and make something out of it
When available, buy J-35
Buy Mi-26 and demolish the Chinooks and sell the parts on the black market, buy Ka-52 or Mi-28 in case of Azerbaijan trouble to ease the process
Keep Yasin and not buy Yak trainer
Continue the Simorgh project
Inject liquidity so Iran can buy all of that
Work on reliable and producable tank project with China or Russia after the war
Shuffle mix the air defense layers by adding S-400 and if possible S-500 to the long range layer roster of SAMs
Buy S-350 for shuffling the mid range layer
For the SHORAD, buy Pantsir S2 and place them at the Azerbaijan border along with Iranian SHORAD, they proven efficacity against Israeli and Turkish drones
Reverse the Javelins, NLOS, Stingers that Russia delivered
Try to negociate for a bomber such as Tu-16-95 or H-6 from China to bomb targets in neighboring country and make Iran progress in making massive ordnance weapons
Buy BMP-T, again in case of Azerbaijan
Single engine attack jets are not made for a large country such as Iran
Iran is a very large country and Su-35 fits the role, the only problem are the numbers. This is not a F-5 with some internal upgrades and an upgraded ejectable seat that will defend the Iranian airspace
Iran needs fighters that can cover large distances to defend the mainland, this is not something that "Kowsar" or JF-17/J-10 would do unless bought in massive numbers
