Keywords: supersonic wing, lift-dependent drag, optimization

Minimization of drag due to lift in supersonic flow is considered. It is founded that the near to optimum wing consists of elliptical cones and flat elements passing through the wing apex. The results of theoretical analysis and direct numerical optimization are compared for different flight conditions.
