Yes, Mister B. They've got a lot of helos. Actually they have quite a lot of FJ airframes, but a lot are wrecks. Also, remember that Iran is a massive country with only 14 Tactical Air Bases (and some auxilliary airfields). So not much in the way of contemporary air and a huge chunk of airspace to cover.
Radar is another problem. Again a big space to cover. I don't think I can report any AWACS, athough there was talk about getting one from Russia - don't think it happened. Possibly a VHF, anti-stealth radar, but how much can one cover?
Thinking about SAMs, long range systems are located through the centre of the country and in the West - SA2 and SA5. Tactical systems are positioned, as you would expect, around strategic and population centres - mainly S200 and Hawk (yes, US sold them, they've kept them going).
There are one or two modern things, but...
That'll be Iran's high tech modern air force then.
