The FMU-139 series tail fuzes are electrically initiated by what initiator?

Explanation:
FMU-139 tail fuzes are designed to be fired by an electrical initiator. The specific device that provides the firing energy for these fuzes is the FZU-48 initiator. When the aircraft sends the arming/firing signal, the FZU-48 converts that electrical input into a detonator-igniting impulse inside the fuze, triggering the explosive train at the intended moment. Other initiator models (FZU-22, FZU-50, FZU-60) are used with different fuze families, so they are not the standard initiator for the FMU-139 tail fuzes.
