It's a little bit early to write the F-35 off as a failure, unless you're talking purely about the financial side. Certainly it's a failure as a down-market F-22 with strike capability. It's far too expensive for that. We won't really know what kind of air superiority platform the F-35 is until it's had a few run-ins with other modern fighters. Stealth capabilities and superior sensors may be more than enough to make up for lack of maneuverability. Or maybe not.
