Given the cost of the F35 not sure how you can call it a low end fighter. And I suspect it's the other way around, the F22 will be supplementing the F35.
Given the cost of the F-16 today, I would hardly call it a low end fighter either. Thing is, the F-35 increasingly
is living up to its billing as the F-16's successor in terms of the global sales it is racking up.
