One of my favorite books: https://www.amazon.com/Boyd-Fighter-Pilot-Who-Changed/dp/031...
There's a lot about what's wrong with aircraft procurement in this book and how he fought against it. Idealism and pragmatism still lose to politics and money fifty years later!
I guess it's fortunate that technology continued to advance to the point where the F-16 finally does have improved RADAR and BVR (Block 20 and onward).
But, yeah, they had tunnel vision about the mission.
The F-16 was the card up Boyd's sleeve that nobody saw coming but couldn't argue against it once he put it on the table!
The F-16 did not conform to what Boyd wanted out of a combat aircraft, execpt for the lightweight part. The F-16 has a RADAR, BVR, and while designed as an air superiority it has exceeded expectations as a multirole platform.
So for those of us not interested enough to actually go read that book, what is the solution for such insanely expensive military programs?
The incremental cost of a F35 once you have designed it isn't too bad (and it could be made a lot better if it was worth a larger assembly line to make more).
