Well there's an awful lot riding on this 'stealth capability', probably too much. Take away stealth and the F-35 is a bad plane that nobody would want, especially the B variant.
When the UK and others signed up to the B variant, they were given the illusion that it would be the same as the other two but VTOL. It turns out to be nowhere near the truth.
1) It's STOVL, providing the problem of recovery landings on aborted mission.
2) Its range sucks.
3) It can't carry any standoff weapons internally. Not the JSOW or JSOW-ER. It can't carry 2000lb bombs internally either. The A and C can do both these. As for JASSMs or Storm Shadows, not even close.
4) Dogfight - can't do it.
5) Survivability - stealth yes, but only one engine (and blows up in lightning).
Funny that the Chinese, for all their alleged blind copying, weren't stupid enough to built a single-engined carrier plane. Credit where credit is due.
I don't think the BVR advantage will play out as well as it does in training with 90-100% simulated success rates for AMRAAMs and WVR a Rafale M will f*ck an F-35.
As regards interdiction and denied access areas. Even assuming the F-35B has the range to reach them, without external tanks, why bother when I can launch a KEPD 350 from 500km away and not even have to access the airspace. Or even a Tomahawk/MdCN from maybe 2000km away.
SEAD? Can the F-35 carry HARMs internally? Nope. Certainly not the B variant.
Whilst it has all this supposed stealth image thing going for it. I don't see it being the magic bullet, mostly because the people building it either weren't thinking, or made so many compromises to achieve stealth and STOVL that mission capability was sacrificed in a big way.
Stealth - yes. STOVL - yes. Capable fighter - no.
