First of all they came as kits that Iran assembled. So it seems you are a bit clueless on the whole process. Then you start jumping topics and rambling that Iran should have gotten license for AL-21F or an airborne radar, completely different topic altogether and ignorantly ignoring the history of Russian-Iranian arms deals.
Russia in 1990s was in shambles and desperate for currency and ways to pay off its debt hence for example Slovenia got a nuclear reactor, South Korea various military hardware.
You deride the T-72 license deal even though it gave Iran much more ToT then the puppet deals like M60 or Chieftain ever gave Iran.
I do not care about pre-Revolution Iran and it is about what Iran achieved in restoring operational capability of military hardware during and after Iran-Iraq War.
Iran did not need another set of road wheels and tracks of lower weight carrying capacity along to complicate logistics further.
But since the West sold those to Iran, of course you praise them.
Where did I praise them you bloody liar...
Also the T-72 is literally the most successful export tank in the world and a T-90 variant would wipe the floor with a next gen M60 based tank.
Success of export on matter of quantity doesn't necessarily equate to quality or longevity.
Mig-21 is most successful export jet with most potent Bis model being designed and produced from 1970s to 1980s...
It made sense to get license production of T-72 by end of 1970s such as Yugoslavia did, by end of 1980s such was outdone by M1A1 and basic Leopard 2 was a match. T-72 was developed as substitute for T-64 that entered service nearly a decade before T-72 while T-90 is further development of T-72 hence has autoloader with more limitations than T-80.
Iran could have made own T-72 on basis of having T-72M1 to study and design comparable tank with parts and technologies that Iran had even in 1990s.
Also Iran sent one or more examples of T-72M1 to North Korea that produced 2A20 115mm smoothbore cannon that is direct predecessor to 2A46 that is 2A20 upscale with some differences. Hence I wonder if really Russia provided tools for production of 2A46 or if Iran managed to acquire production of such prior from North Korea.
But continue your uneducated ramblings. Don’t forget to take your meds in the morning.
Very ironic coming from you that asserts I said something I didn't and yet I am uneducated apparently.
When was the last time Iranian F-4 Phantom II fired a radar guided AIM-7 Sparrow missile?
Anyway Zolfigar would allow single piece munition that is more efficient than two piece hence less need for exotic solutions to increase performance of APFSDS as longer rod is possible.
