Within the context of NGAD, I've been thinking the same. If the Raptor is the unanswerable weapon of the skies (per DCS experts

), why are we reinventing the wheel? Add those "stealth" fuel tanks and a one-time ECM for the real-deal... like everyone else. If it's expense to maintain, put NGAD-$$$ into making your logistics/servicing footprint better + cheaper. Yes, restarting the production line is expensive, but to the layman it would appear on paper to be much less expensive than starting from scratch.
It feels like they're "throwing the baby out with the bathwater." I mean, with all due respect to the F-15, She has never been shot down. Why is She obsolete again? We still use Viper-Cs in many capacities, etc. I would love for an expert to articulate for a layman why the F-22 is suddenly useless. Even if She isn't invincible like before (in theory*) is there really Zero confidence that the F-22 can be dominate in a competitive fight? Same goes for the F-15. The IDF still makes very effective use of the Ra'am.
