Except for the F111 and F117, neither of which could by any standards be called fighters
Touché!
Although in fairness the F-111 was intended to become a fleet defence 'fighter' in B spec, and the F-117's nomenclature could be put down to a bit of obfuscation given the secrecy of the project.
One might also add F-105 to the 'doesn't quite fit' list.
SR: Strategic Reconnaissance. Although its predecessor, the A-12, also 'doesn't quite fit'.
