The F/A-18 does it's job well as a light fighter/attack plane, and replaced the F-4 in the Navy and Marine Corps as such. But its was never, ever intended to replace the F-14 in the fleet defense role...it is out of it's league in that role!
Indeed, we need to call Dick Cheney on the carpet for his allowing the F-14 titanium wing-box tooling to be destroyed back in '91 when he was SecDef.
We should have fired up production of updated versions of the F-14. How long can we keep the old war-horses flying?
