I had thought that was exactly the problem with the F-102;
that it was NOT area ruled.


The YF-102 was not area ruled, the YF-102A and later models were.



My quick and dirty reference (the one which most readily
falls to hand) indicates that the F-102 had a max speed
of 825 mph with a J57-P engine,

The F-106 is listed with a max speed of 1,530 mph with the
the same J57-P engine.

Something has to be going on there with the aerodynamics to
account for an 85% increase in speed with essentially the
same engine producing essentially the same thrust.


They didn't use the same engine, the F-106 used the J75-P-17.
