A supersonic flight aircraft having a longitudinally forwardly extending fuselage having an axis in the direction of flight, and a wing, and which comprises the wing extending generally laterally relative to the axis, and having a leading edge angled forward or rearwardly relative to a normal to the axis at an angle , and the wing having leading edge sharpness defined by upper and lower wing surfaces, which taper toward the leading edge to define an angle .delta., closely proximate the leading edge at all spanwise locations; the angle and sharpness .delta. characterized in that at design supersonic cruise flight conditions, the wing has an attached shock, that is, the forwardmost shock wave produced in association with the wing extends generally along or rearwardly of the leading edge, whereby laminar boundary layer conditions are maintained over the leading edge and adjacent the surface of the wing; there being flap means associated with the wing leading edge that comprises upper and lower leading edge skins capable of being controllably expanded chordwise, a structure between the skins, which permits the chordwise expansion of the skins, and means for causing relatively greater chordwise expansion of the upper skin than the lower skin, to generate downward defection of the leading edge.
