Is it? By what criteria? IMHO the point is to get new tech out quickly enough that you aren't falling behind other major powers in the international arms race. The F35 seems to be ahead of the competition because countries around the world are lining up to buy it over much cheaper alternatives from Russia (Su57) and China (J35).

Not to mention that the Su57 also had about a 20 year development cycle. Maybe that's just how long takes to develop a new stealth fighter?
