Meanwhile, PAF may look into the following options:
1. Scaled up JF-17 with a bigger engine (Western or Russian).
2. Scaled up JF-17 with twin RD-93MA engines.
Any of these options will ensure increased payload capacity and combat range.
I really don't understand why these ideas always pop up again and again? What sounds so logical and easy is in fact ridiculous since it would result de facto in a new aircraft, even more it is what we are joking on these constant Indian ideas as if scaling up the Tejas to the Mk.2 or even Orca would be easy!
And by the way ... what's then after years of development and the spending of billions of $$$$?
Option one, a "Scaled up JF-17 with a bigger engine (Western or Russian)" would be what the J-10C already is and option two, a "Scaled up JF-17 with twin RD-93MA engines" would result in an unstealthy fighter comparable to the stealthy FC-31/J-35 but it won't be available earlier.
As such, IMO simply forget them as a waste of time and money.
