Tail appears to be straight, as we have in JF-17 Block I/II instead of B. Do you agree? If this is the case, that would mean something interesting;
We know JF-17 Block III will equip a heavier AESA radar, yet we find a vertical tail is in use. JF-17B was said to need a slanted tail to compensate increase frontal-load (2nd Seat). Since Block-III is using old tail stabiliser yet it has a heavier radar, does that weight balance is provided by a heavier and a new engine? AESA radar would also need more power, so a newer, more powerful engine would make sense.
And a newer more powerful engine actually means, even a wider wing-span to carry even more fuel - and that changes the category of Block III from light weight aircraft to medium weight aircraft - that leads to more hard points, longer ranges and increases loitering time to challenge Su-30s and Rafael - and I suspect speed would also increase - possibly to Mac 1.8?
What are your thoughts ?
