I've been saying for some time that the low vis effort is a waste of money and that radar was developing the ability to see them. Yes, just how far out they can see them is an important point. The Americans seem to have drawn the same conclusion as the supposed new replacement for F35 isn't low vis. Once you discount low vis, just how good is the F35B? The USAF has been reported as not having a high opinion of the F35. But then I am a crusty old cat and trap man who thinks that our carriers would be a whole lot more useful if they had them.
