What triggers the detonation of an air-to-ground munition fuze before detonation?

• A. Proximity Fuse
• B. Timer
• C. Target Lock
• D. Electrical impulse

Answer: (D)

Electronic fuzes in air-to-ground munitions are activated by an electrical signal from the aircraft or the release system. That electrical impulse powers the detonator and starts the fuze’s firing sequence, allowing the warhead to detonate at the chosen moment or distance (for an airburst or other pre-set detonation point). This method provides a controlled and safe arming process, so the weapon doesn’t detonate due to harmless handling or flight vibrations.

Proximity fuzes detonate when sensors sense the weapon is near the target, not from a signal sent to the fuze. A timer fuze detonates after a preset time, independent of any electrical impulse from the aircraft. Target lock relates to guidance, not the fuze initiation.
