Maybe they got mothballed because they were so easy to track over Bosnia.. Cellphone triangulation or something like that.
The dirty secret of stealth is that SAMs will get them again very soon. They have always been able to “see” them, tut computing power wasn’t there to make sense of it. NOw computers can notice and analyze the “hole” in the sky where the stealth is, and target it.
Stealths were never truly invisible.
As computer power expands at an exponential rate, the SAMs will be back in the drivers seat again. And we will be married to a bunch of retarded F-35s that paid a huge penalty for their stealth that was stealthy in 2011, but not so much anymore in 2019.
And then they will scrap the F-35s and build some new design!
