BTW, if T/W >> 1, then all you need are control surfaces, and these can be relatively tiny.
Aircraft designed to operate primarily at supersonic speeds also don't need nearly as large a wing as aircraft designed to operate at subsonic speeds. And the design considerations for the wing are different. As one of my aerodynamics professors put it "the ideal supersonic airfoil, barring any practical considerations like stiffness or the fact that the plane needs to fly before it goes supersonic, is a flat plate"
