“limited”?
Do tell...are you privy to the actual data that supports your assertion?
Just look at any analysis of the F-35’s stealth abilities - no where even close to the F-22 and perhaps not even up to the B-2 - remember this is a composite plane designed by committee - and cannot carry long range weapons internally as they are too big - can only carry them externally thus negating its limited stealth.
As for giving you data - that’s lame - go look for yourself.
