An almost symmetric missile is a missile whose zero-spin pitch and yaw frequencies are nearly equal. The angular motion of a spinning almost symmetric missile can be described by five rotating modal vectors. Two of these vectors vanish when the frequencies are equal. Good approximations for modal frequencies and amplitudes are derived for the special cases of near zero spin and spins near pitch or yaw resonance as well as for spins away from these special regions.
