What is a characteristic of impact fuze types?

Impact fuze types are specifically designed to detonate upon contact with a target. This characteristic is crucial in various military applications, where immediate detonation upon impact is essential for maximizing the effectiveness of the munition. For instance, when a projectile strikes the intended target, the impact fuzes ensure that the explosive functions as intended, creating the desired effects on the target.

The other options do not accurately describe impact fuzes. For example, fuses that are designed for delayed detonations do not qualify as impact fuzes since they require a wait time before activation. Impact fuzes need to activate instantly upon impact, contrasting with any mechanism involving a delay. Furthermore, impact fuzes are not limited to naval artillery; they are commonly used across various military branches, including artillery and air-delivered munitions. Lastly, suggesting that they require a long delay before detonation is fundamentally inconsistent with their purpose, as they are aimed at immediate detonation once they collide with the intended target.
