Iran has the following missiles below. All systems have had countermeasures developed against them. They also have not taken delivery of Russian S-300s. You can bet on the reds helping them by providing these a la Yom Kippur ‘73. If S-300s are deployed, it’s guaranteed that the US will be in this and using 5th Gen aircraft (F-22s) for SEAD/Wild Weasel.
Iranian SAMs:
MIM-23 Hawk
SM-1
Tor-M1
S-200
HQ-2
SA-3
SA-6
HQ-7
RBS-70
SA-7 Grail
SA-16 Gimlet
SA-18 Grouse
Still no S-300? That puts Iran’s air defenses in pretty poor shape.
