"the "cheaper" F-111"
The F-111 was ok, but the F-111B turned into exactly the kind of clusterfuck that the F22 and F35 have become and got cancelled (The F14 and F15 did come out of the R&D as "smaller, cheaper faster" aircraft though)
The lesson learned from the F-111 experiences appears to be how to structure your program so it _can't_ be cancelled.
