Saddam also believed that he didn't need an Airforce! He was totally proven wrong, when his Air defences were suppressed and systematically eliminated.
I totally disagree with the notion that Iran does not need an Airforce anymore.
I don't think Iraq and Iran are comparable, its apples and oranges. The terrain alone is completely different, the size of the countries are different, the airdefense networks are different
and no one says Iran does not need an airforce.
The conclusion that many have come to is that for the short term, Iran needs to invest into airdefense and missile technology rather than purchasing fighter jets.
It's an economical reasoning and long term planning.
This doesn't mean that they do not need an airforce, or are not developing a fighter jet.
Without a powerful defensive Airforce Iran is at the mercy of the aggressor.
This will bite us on the ass, and will leave the NATO and US fighters free domain over our air space. They can come in and go as they please.
Iran should lobby Russia to start the supply of the Su-30's to replace all of the obsolete F-4, F-5 and F-14's immediately. Iran's leadership should request CHina to start helping out on a J-20 type local development on an urgent basis.
I'm not sure, but i think the F-4's, F-5's and F-14's Iran have are highly upgraded. How much this upgrade will be able to compete against modern jets, is up to question, but many many people say its not the fighter that is important but the AA missiles, radars and pilot skills which will determine the dog fight.
