The tail fuze of FMU-152A/B uses which initiators?

• A. FZU-55A/B or FZU-63/B initiator
• B. FZU-48A/B Initiator
• C. FZU-38A/B Initiator
• D. FZU-70A/B Initiator

Answer: (A)

The main idea is that tail fuzes need an electrical initiator to start the detonator train at the right moment. For the FMU-152A/B tail fuze, the design specifies the use of FZU-55A/B or FZU-63/B initiators because their electrical characteristics are matched to the fuze’s arming and timing circuitry. These initiators reliably deliver the required energy to initiate the detonator train when the fuze is armed and the fuse conditions are met.

Other initiators listed are not compatible with this tail fuze configuration, as they are designed for different fuzes or electrical interfaces. Using the correct initiator ensures proper arming, timing, and reliable detonation timing for the FMU-152A/B.
