The Thud was conceived and did well at moving dirt. Lots of glowing dirt to start with and yellow mud to end up with. The mission of the AF and Navy is to support the Army (expecting lots-o-traffic on that one), and that means moving the dirt the Army tells us to move. Air to Air is a pipedream that has little to do with the outcome of many wars (BoB being the only known exception). At the end of the day, it is who owns the dirt and that is the Army's ball game. With that in mind, the Thud, in its time, was prime in the dirt moving arena. That is what she was built as and performed in an exemplary manner. Making her an Air to Air fighting machine requires a complete overhaul, not just more thrust. She was great at what she did and she deserves more than conjecture on how she could have been a jack-of-all trades and master of none. We have old double ugly (F-4) for that.
