Then build more. When you have a great design, it’s hard to improve on it.
The process of re-opening the production line would be as expensive as developing a new plane - the dies, etc. have all been scrapped.
And we CAN improve it on it - better thrust to weight, more PGMs, better all-weather capabilities, etc.
But, truth is, we might need to downgrade - we don’t need super tankbuster as much these days, as we do flying tractors ready to dump PGMs on target when called for. Quantity might be better than quality for most applications right now.
