Which statement best describes an Impact Fuze?

• A. Designed to function upon impact or after a time delay.
• B. Designed to detonate only on impact.
• C. Designed to detonate due to proximity.
• D. Designed for hydrostatic detonation only.

Answer: (A)

Impact fuzes are designed to function when the round actually contacts the target or after a short, programmed time delay. This dual capability lets you choose immediate detonation on impact or a deliberate delay after impact to achieve a specific effect, such as timing the explosion for optimal fragmentation or allowing penetration before detonation. The option describing detonation only on impact misses the delay feature, and proximity fuzes detonate near the target rather than on contact, while hydrostatic fuzes are triggered by water pressure at depth. So the description that covers both immediate and delayed detonation on impact best captures how an impact fuze operates.
