A jet bomb guidance system in which bi-directional nozzles are fired in a manner to produce force state changes resulting in improved level of control, greater force compatibility and greater efficiency in propellant fuel usage. The system includes four bi-directional nozzles spaced at 90 degree internals in which at least four single nozzles are open at any given instant to maintain a substantially constant gas pressure. The system may be positioned at the nose portion, tail portion, or center of gravity of the bomb.
