Abstract
A missile launch safety enhancement apparatus (135) for inhibiting the launch sequence of a missile launched from an aircraft-based or land vehicle-based missile launch system. The apparatus (135) incorporates means for producing a prefire signal (102a). The prefire signal produced is then compared to a reference signal level by comparing means (167). If the prefire signal is not below the reference signal level by a predetermined amount, interrupting means (216, 240) inhibits the firing sequence of the missile and thus prevents the missile from being launched. If the prefire signal is below the reference signal level by a predetermined amount indicating proper current drawn by the circuit, the firing sequence is not inhibited, and the missile is launched.
