Really? You wanna excuse the absurdity of the F-35 with the fact that Iran's modern Defense industry didn't really start till nearly a century after the U.S.! That's your excuse?Turkey of a platform? Here we go again...
First, am going to be a dick about this and ask what contribution to aviation have Iran gave for you to call the F-35 a 'turkey'? Sure as the sky is blue that the sentiment DID NOT came from experience, either personal or national.
Second, all the criticisms leveled at the F-35 have been laid to rest. Everything from it supposedly cannot maneuver 9g to it burning up ship decks.
Your usage of the word 'platform' is meaningless. It is too generic. Try again and try to be more specific. And if you bring up Pierre Sprey, I know you are out of touch.
In terms of platform the F-35B may be an improvement on the Harrier so I don't have much to say about that however as a replacement to take over most of the U.S. fleet it is a platform that is SLOWER & Less Maneuverable then an F-16 (armed for air combat with 2x AiM-9 & 2x AiM-120) let alone most of it's +4th gen adversaries and competitors like the Su-35, MiG-35, Typhoon,.... let alone future 5th gen's like the Su-57 that can super cruise faster than the F-35's max speed which are the future adversaries that it would be facing and it's so called stealth capabilities where again challenged and made out to be a joke by a dinky little German Radar in Germany just recently so it would seem all the F-35 is left with is it's sensor superiority and advanced radar which is something that can be matched and out matched through future upgrades to previously mentioned platforms. And if the F-35 truly lacks the proper stealth and clearly lacks the proper maneuvering capabilities to fend off incoming SAM's and at the same time does NOT possess the speed and maneuverability to fend off and run away from modern interceptors add to an absurdly high price tag is what makes it a turkey of platform whos total reliance is on it's sensor superiority and the hope that a single scratch doesn't wipe out the aircraft stealth capabilities when in stealth mode.
And since you brought Iran into this. As I mentioned the U.S. Defense industry is nearly 100 year's older than Iran's (and I'm talking modern weapons post industrial steel) and the main reason for that is due to one corrupt Iranian King after another over half a millennia that where either fooled by foreigners or allowed them to dictate our policies! And that's why once Iran had it's 1st Democracy the Brits and the U.S. did all they could to overthrow it and so they did and now that we have our 1st Republic you are still at it again and have been at it for 4 decades!
Do you understand that under the previous Iranian Monarchy (Phalavi's the U.S. #1 regional so called ally) Iran had a leadership that literally begged for 40 years to get their so called western allies to sell Iran a single industrial Steel Mill? We had morons as leaders that chose begging their masters for over 4 decades to buy a freaking steel mill over actually doing the work with less money to build one themselves. And we are not talking rocket science here rather industrializing a process that's been done to build knifes and swords for centuries and something the Germans industrialized what in 18th century?
And the filed of Aviation is ~ a century old technology that Iran only really started getting into little over 30 years ago which puts us behind 80 years in terms of overall experience and over 50 years behind the U.S. in terms of various infrastructural requirements and in some areas less and some areas maybe even more. However now unlike before where we had a leaders that begged to buy steel mills we have a leadership that is attempting to close that gap domestically and the reason the progress appears slower in Iran than countries like S.Korea or Israel is because unlike them due to sanctions no one is handing us the engine and other vital parts, materials & components. And today due to proper leadership those sanctions have failed to persuade Iran from not pursuing those fields but rather forced us to do the work ourselves and that's why it's taken us longer. However due to those very sanctions the experience, tools, and infrastructure gained puts us a step ahead of countries that only appear ahead of Iran because they got to buy the engines, buy the high end composites, rent out foreign testing facilities to test their landing gears and other vital parts, buy and import the sensors, avionics,.....
So as long as Iran keeps putting in the work domestically in the grand scheme of history that 50 years gap the U.S. has in some areas of infrastructure will slowly dissipate but that's something that will take time and it's not something that will happen today, tomorrow or even in the next 3 decades but it will happen and in the grand scheme of history this little gap will mean nothing.
