Immediately after the 12-day war, Iran began rebuilding its air defenses. There were numerous reports of Chinese cargo planes arriving in Iran. Apparently, Tehran, after the expected failure of the Russian S-300 and local systems, decided to purchase Chinese HQ9 systems. It seems they, too, can't see not only the F-35, but also the F-15, F-16, and even the B-52 (

), which are impossible to miss.
One might assume that the enemy's electronic warfare system simply blinds them.
In any case, they, too, are either disabled or destroyed.
Without air defense, Iran is completely defenseless from the air.
It's interesting that in Ukraine, for four years now, neither side has been able to achieve the astonishing success that the US-Israeli air force achieved in Iran in just a few days.
And we all know how that ends, sooner or later.
