America's fancy new fighter jet stinks at fighting. And the US Navy doesn't care.

As far as I am aware RAM coatings issue is due to underlying basic physics, unless US not only had a theoretical breakthrough in radio physics on Ufimtsev level, but also a simmilar breaktrhough in relevant material science and implimented those breakthroughs, then such changes are not possible.

I am not aware of such breakthroughs. And, in all likelyhood, we would be if they did occur 10 years ago.

My point is that the improvements in radar technology outpaced the reach of stealth, as permitted by known physics principles. This was due to increases in power (ie new naval L-band radar with around 1.5 mega-watts of impulse power and 1.3 consumed), improvements in mobility. This would be further improved via the GaN and better modules becomming availiable in the near future (GaN gives around 40 percent average emited power efficiency vs 20 currently availiable).
Improvements in signal processing methods and means (multistatic arrays, reverse SAR) would further improve counter stealth detection to the point, where it becomes irrelevant, as you would be able detect tertiary effects of aircraft flying through air even if aircraft itself is invisible and primary/secondary effects are fully supressed.
