Abstract
An device for correcting the in-flight trajectory of a munition consists of an impulse motor assembly body. The slug or multiple slugs and propellant(s) are located within the impulse motor assembly body. When a trajectory correction is desired and required, the individual impulse motor propellants are activated and fired, and the slug or multiple slugs are propelled out of the in-flight munition at a specific time and a specific angle on or near the gravimetric center of gravity of the in-flight munition. The reactive forces created by the explosion of the(se) heavy metal slugs does, by equal and opposite reaction, create a corrective vector and thereby does cause a correction in the trajectory of the in-flight munition.
