Early pre-contract prices were estimations, not "promises" and reflect a completely different Baseline Year [BY] (=inflation adjusted year).
Most people only quote the "cost" without stating the the BY.
Btw, it's only "overpriced" if it's somehow not worth the new price. The recent Red Flag has put that argument to bed. Don't get me wrong, they blew the contracted cost but the DoD & Partners are still satisfied with it at it's current price curve.
As far as "outdated" (no longer useful or acceptable : not modern or current), please tell me how that applies to the plane as a whole?
