An apparatus and method for separating a warhead to be delivered to a target from a carrier missile flying at high speed in a first aerodynamic trajectory include a rocket motor attached to the warhead in the carrier missile and an ejection tube positioned obliquely in the carrier missile rearwardly and upwardly with respect to a longitudinal axis of the carrier missile from which the warhead is ejected by the rocket motor into a second aerodynamic trajectory having a substantially higher maximum flight altitude then the first trajectory. The warhead is separated from the rocket motor after ejection by aerodynamic forces created from the angle of the ejection of the warhead from the carrier missile and the relative flight velocities of the warhead and the carrier missile. The aerodynamic forces act on a connection between the rocket motor and the warhead, whereby the motor and warhead upon the burnout of the motor follow separate forward trajectories upon separation.

DETAILED DESCRIPTION The object of the present invention is to devise an extremely simple solution to these problems.
The invention, which has otherwise been defined in the appended claims, is thus based on the concept that the communication between the warhead and the rocket motor is such that the aerodynamic forces and inertia forces acting on these units bleak down this connection as soon as the rocket motor has burnt out and no longer acts on the warhead in the flight direction.
This fundamental principle (which is illustrated in the accompanying drawings) may thus consist of a loose lap joint in the form of concentric ring edges of relatively low height disposed inside one another.
