The Deuce didn't go supersonic as originally designed, but was about 1.3 when the fuselage was area ruled to account for the cross section of the delta wing. The F-106 was designed area ruled on the design board.
What is more interesting was how long it took to use area ruling in subsonic planes. Most business jets (mine, for example and the Citation X. "Mine" in the I fly it sense) now have area ruled tail cones, as did my namesake's tail.
