I'd have to say, I don't know either way, if stealth aircraft can do all they claim.
But with that said, I'd dare to add, I don't think you have that information either.
The issue with the F-35, in regards to Stealth capabilities, is that the price is too high, for an aircraft that is at the same level as the F-117, referred to as the "Stealth Fighter."
Although it has been used, almost exclusively as a night mission bomber.
We have seen a couple situations, where stealth aircraft were shot down. Weather by luck or because the shooter could see the plane, we don't know.
So, is the F-35 to be another night plane?
It's for certain that it's visible enough in daylight, and if it's detectable on radar, then it's worthless as a stealth plane.
You may not want to hear such talk. But it needs to be said and discussed. The truth needs to be known about this plane, long before it reaches the front of the next battle.
