Which type of fuze is initiated after a weapon strikes a target and aims for deeper penetration?

The delay fuze is designed to initiate after a weapon strikes the target, allowing for deeper penetration before detonation. This type of fuze is particularly useful in scenarios where the desired effect is to breach through obstacles, such as armor or protective structures, ensuring that the explosive charge detonates at the most advantageous moment, thus maximizing its destructive capabilities.

In contrast, proximity fuzes are activated by the proximity of the weapon to the target, often used for airburst detonations. Impact fuzes detonate immediately upon contact with a target, making them unsuitable for scenarios where penetration is required. Combination fuzes might incorporate elements of both impact and delay mechanisms, but it is the delay fuze alone that specifically addresses the need for deeper penetration following impact. Therefore, the choice of delay fuze aligns perfectly with the requirement specified in the question.
