Ballistic missile and drone programs were a huge success that a limited number of planes built or bought(also considering delivery issues from Russia) under sanctions could not achieve.
Anti drone/aircraft mobile lightweight sam systems like 358 and Majid were a huge success too. I pray mini-submarines would also do some significant moves later on as well.
High altitude radar based sams like bawar-373 and Khordad were not successful though but It couldnt be known beforehand. Jamming, saturation attacks and stealth negates most of their usefullness. Some paradigm shift is necessary for high altitude defense. Are all Karrar drones destroyed for example. They can do some moves against enemy aircraft patrolling around sensitive areas like Iranian nuclear powerplants that are under immediate threat for example.
Attaching a mini high altitude capable a2a missile like R60 is not difficult Russians did it on shaheeds. 2+ R60s can be installed on high altitude capable Karrar. Airfields are not necessary since it can be launched by rato and recovered by parachute.
Also there are new cheaper stealthy drones that are used for emulating targets. But looking at the shape it seems it is not that easy to lock on them by airplanes at least. Attaching a lightweight missile like R60 under its body would not be too difficult. while flying at 8-10km altitude enemy planes flying higher like 14-15kms wont see the R60 under its body from most angles. It cant be made bvr air to air capable or it cant carry missiles inside its body but within visual range they can be pretty effective guided by a ground radar(passive preferrably).
