A method for compensating for pre-reentry errors generated by the weapon delivery system to provide a reduced impact range error dispersion over that provided by a ballistic trajectory after reentry comprising maneuvering the reentry body after reentry so that the terminal flight direction is essentially in line with the line of means of the reentry bodys position-error ellipse that exists just prior to reentry. The reentry, a dive maneuver including an optional pullup leg and a pulldown leg to establish the required terminal direction, and a terminal ballistic leg to impact. The required maneuvering is accomplished by modulating the aerodynamic lift of the reentry body by controlling the reentry bodys roll orientation.
