you havent got the point about irans AF buying new planes,its just the matter that russian and the chinese wont sell us the things they making like the SU27 or J10,we can obtain smaller things from them like the TOR M1 but they are scared of US and wont sell us the new stuff the IRIAF needs,If the F14's were that good then I amn sure the US wouldn't have inducted as many F!5's and F16's in there airforces. As far as the radar goes the F14 is an effective mini AWACS because of the size of its radar housing rather then just the quality of the radar. The SU27 can make a much better command post or AWACS system than the F14 due to the fact it is more modern and able to utalise Westen European based tecnhnology (China and Indian examples). Iran's military doctorine seems to be rather peculiar. They can easily afford to buy SU27's because that are not that expensive, but for some reason they have not chosen to do so. I ma not sure if they have purchased the Mig 31 and use that for datalink and command post operations.
so we have to keep the things we have airworthy and work on our own domestic aircraft.
everycountry started from some where ,didnt they?!
if the shah along side buying US planes had started working on domestic fighters,maybe now we could build some thing close to the gripen or eurofighter,after about 50years of expreince
