A mathematical model for unguided-rockets' motion in the air taking into account the deflection of the thrust vector and the position deviation of the center of gravity is established. The mathematical model is solved for specific rocket slow spin. Some calculated results then were compared with standard values given by its supplier. The effect of the disturbance factors on the motion stability is shown through the deviation of the graph of the angle of attack and the trajectory dropping points compared to the corresponding values of the standard trajectory, which does not contain deviations.
