Why have most newer fighter designs not used swing wings?
It seems in the US, the F14 and F111 were the last to go with
swing wings. It seems the major reasons for using them is having the
best of both worlds in wing loading at both low and high speeds.

Why have the newer designs avoided them? Maintenance?
Weight? Cost?

Also, most newer fighter designs use twin tails canted out from
perpendicular. Is there a reason this is better than straight
dual perpendicular tails?
