Well, it is if we look at what existing planes are capable of and assessing whether their performance would be adequate or not, hence the T:W ratio comparisons.
well no, because only looking at T/W doesn't tell us how much stealth contributes to survivability as well, nor do we know how capable the opposing side's air defences are projected to be.
In other words, to know what the minimum kinematic capability of JH-XX should be,
we need to first project a realistic defended airspace scenario, and then to consider h
ow much stealth contributes to its survivability, and then finally look at what the kinematic requirements will be on top of stealth to reach a desired level of survivability against the defended airspace.
If we don't know:
-one: what the defended airspace will look like and
-two: how much stealth will contribute to JH-XX's survivability against it...
...then we can't begin to project what kind of T/W and minimum kinematic capability JH-XX will need.
It is the lack of knowledge of those two things, which makes me say we can't seriously hold a discussion as to what the minimum kinematic capability JH-XX will need.
