One would think that if Pakistan was to build a 5th gen fighter, they'd be looking to go single engine with an airframe with similar proportions to a jf-17/f-16. It would make sense from a pragmatic view to just reimplement the jf-17 into a new stealth airframe, sort of like the Russian 5th gen fighter. But since the Su-57 has seen some delays, I guess not?
Theoretically, 'stealthi-fying' the JF-17 should be possible, at some level. Northrop did just that to the T-38 Talon through the Model 400. Unfortunately, we won't know how much of a performance improvement it is, but it was aimed at the USAF's next-gen LIFT requirements.
We would need a power plant like the F35 engine to be able to get the performance we want out of a single engined 5th generation AC. I cannot recall any engine with a performance like that. It is therefore fair to assume that a single engined stealth fighter would be a waste of time in the PAC scenario and capabilities sphere. What we could have is a semi stealth lo observable fighter with recessed weapons and RAM coating and appropriate software as a work horse to go along with the Azm. Now whether PAF wants to use another fighter or accompanying drones is something I dont know. Howsoever we look at it we need an interim fighter before Azm comes along. What that might be is not clear.
The reason I write what I write is the need for 100 odd fighters which PAF needs to replace. We dont have the finances to buy anything in large enough numbers to fulfill this need. The next issue is the block building approach of the JFT. This effectively dictates that there will be a newer block/blocks if we need 100 fighters to replace.
j31 or j20.At that moment, what will China or Pakistan have?
One thing for sure is that China would be equipped with a new figher jet from SAC.
i think by 2030 we well see a 6th generation chinese jet.
The work for next generation engines and fighters has started.
the two leading countries in aviation, Russia is out of the picture in this one!
