Stealth was always idiotic. Always. From day one, every single technologist admitted that the advantages of stealth could only ever be short-term. It was a brief technological advantage that was certain to disappear as next gen tracking systems caught up. And they have. In fact, they did some time ago.
The problem the military has is that they are operating on long production cycles when countermeasure innovation is operating on far shorter cycles. This isn't just a major financial blunder -- this is a major strategic blunder and the military hasn't yet had that truth forced upon them: But they will as soon as the F35 sees combat. Reliance on stealth is patently stupid and any student of military history knows what happens when militaries rest on last-gen technology and pretend it's still good enough.
The only path to recover from this strategic blunder is to man-up and accept losses. Accept the reality that manned air combat is already primitive, and to spend 5000% on development of unmanned air combat which can counter Russian and Chinese 5th gen aircraft. And for god sakes MIC, air-gap your fucking computers -- please. You suck at data security.
