The thing's track was still to narrow to be really safe for carrier ops.
So was the A7's (which is more or less a retuned Crusader).
That didn't stopthem from being two of the most successful aircraft the U.S. produced post WW II.
The F8 was the ONLY fighter the U.S. designed and put into service after the F-86 until the advent of the F-15. Everything else was an interceptor or a fighter-bomber. That isn't a bad thing, fighter bombers are damned handy, and the U.S. needed interceptors to kill the Bears, but when you list the actual fighters the U.S. built in the Jet era its a damned short list.
F-86
F8
F-15A/C
F-22
Everything else was meant to do something besides kill enemy fighters.
