Abstract
Abstract The warhead of a missile is loaded with a payload that can either be burnedr exploded. If propulsion is lost and either aerodynamic steering is not present or the velocity level of the missile is degraded to a point where steering is marginal, steerage is maintained by igniting the warhead payload and exhausting gases through nozzles attached to the warhead.
