A three-view of the April 1962 configuration of General Dynamics’ TFX entry. This is very clearly the F-111, but with a few minor differences. The most obvious are the different inlets and the tail “cone.” Here, it appears that at least for the USAF version, the tail cone was meant to angle downwards… presumably forming a ventral fin to aid in stability (or perhaps aid in maneuverability).
Other design features that would change include the profiles of the dorsal and horizontal stabilizers.
