Sometimes... everything is already said and done before you catchup.
I just had to jumpin to remind people, that no SU will be available for dog fight. SU is not a dog fighter and they (Indians) learnd about it even more in US red flag. Still they continue to brand gun, which is useless but JFT should be a smart fighter.
Weightwise, i think your estimate of 250-300kg. is not too far from reality.
Adding CFT will bring back drag but will add potency and performance.
In Indo-pak theater, I would like to see addition of 2x100kg. BVR, instead of fuel tank.
and i also believe... using JF-17 for strafing terrorists is an over kill. Unless its done for show
We can hang a gun with super mushaq and that would do the job.
While, best dog fighter in PAF inventory is F7PG.
