Emir jon.....the F-4 is an old airframe. It is bulky, unwieldy and sluggish at high altitude, but performs better at lower altitudes due to its thick wings. Those J-79's are smoky at it's optimum cruise speeds of around 600knts. But......it's a great bomb truck!
What 10 shahab's will do, one F-4 can carry in ordnance. That is the difference aircraft make.
Iran has a lot of bomb trucks right now in it's inventory, Su-24's are even more capable, and have very high performance.
It's the air superiority types which we are lacking.
Rafighe man lull , I wasnt saying that IRIAF should use the exact Phantom airframe for further development . I was saying that something new in same configuration . Off-course if it would be a 4 + generation then it will be bonded honeycomb base composite based unlike the conventional Alloy of 3rd generation aircraft like Phantom so the weight will be less . Acceleration issues as u mentioned can be addressed once u have the basic weight of the aircraft set , mere function of TW ratio ... The RD-33 or any variant of it like RD93 can produce upto 40 K lbs ( x 2 ) at AF ( provided Russia agrees to deliver them like some 50-75 RD33 came some year back ) Rd 33 , J79 turbojet are roughly same dia , another Engine of same dia in Iran's reach is Al-21 of Su-24 and Mig-23 ( variant ) . Maneuverability can be addressed by incorporating a Negative RSS through 4 channel FBW and a basic FLCC . it will make a good Aircraft ... IMO Phantom design had alot of potential but corporate politics resisted any furhter evolution . The Israelis made Kornas 2000 based upon Phantom E and it was an equivalent of F/A-18 C/D ... Another advantage is that Iran knows everything abt this design , its + and - ... it will take alot of less time in research then studying something new .... had Iranian Aviation brains took more interest in Phantom rather than obsessing with F-5E based designs ( Azaraksh and Saeqeh ) then today we would have been alot better .
The best solution INMO is to reverse engineer the Su-30MK. But Russia refuses to deliver under foreign pressure. China is another source for the Flankers, but it is also under close watch by Russia now because of copy catting behavior.
The Flanker combines the best of both worlds in strike and air combat capability. The JSF/ F-35 is inferior to late generation Flankers in performance. The Su-30's of the Indian AF have repeatedly beaten late generation F-15's and F-16's in actual mock combats over and over again in Alaska and again in Singapore.
The only thing that outclasses a late generation MK Flanker right now is the F-22, and that too by not much. With AESA retrofits that Russia is making available to replace the Bars N011M will make the MK series highly competitive.
The PAK-FA/ Sukhoi T-50 is developing into a beast that will dominate the air for decades to come. It is far more maneuverable and deadly than even the Flanker with 5th Gen weapon systems, LO profiling and all weapons and fuel stowed internally. Russia has spent more than $20 billion developing it.
Anyway if its of any interest here is the link to the AUS airpower article on the Su-30MK series and how it competes with the latest 5th Gen types, and how many times the threat of the advanced MK series have forced the Boeing designers repeatedly back to the drawing boards:

Lull I know how capable Flanker is ... Chinese , Indians are not fools that they r acquiring it in heavy numbers even with other options available . If i remember correctly Indian Flankers won against F-15C of USAF , but eagles were restricted to WVR only .
but problem is same again ... will Russia agree ? or Chinese ? or even Indians ? .... Russia backed out from merely a defensive weapon i.e. S-300P then how can we trust it with giving iranian engineers access to most sophisticated thing of its current fleet ? ... They might agree to provide us with Klimov or Al-21 turbofans ( through third party ) or or Zhuk M or A Radars if we r lucky but i dont see them agreeing in giving us Flankers ... They r friends and (my father was born in USSR lol ) and they have given us everything
they can but , they like us are very isolated themselves now . Russia , China , India ... all are friends but they have their problems in dealing with us .
so its better to learn from past .... Use composite based Phantom design ( with modifications off-course ) , add modern FLCC , 4 channel FBW , negative RSS ... Use RD-33 turbofans . I wont mind a local turbojet J79 either provided performance is enhanced . Seek Zhuk M radars from Russia along with additional R-77s .....Go the assembling route Like India did with its LCA
another simple approach .... buy 2nd hand Mig-29s from wherever available in world , I heard Hungry and Malaysia are up for sale or even from Russia through Syria ... Its an easy solution . Additional Mig-29s ( if we manage to get some
50 more ) will instantly boost the deference capability but with R-77 . Its a more practical , instant and easy approach .
