What effect does an improperly functioning Safe and Arming Device have on a weapon?

An improperly functioning Safe and Arming Device can indeed lead to premature detonation of a weapon. This device is critical in ensuring that an explosive munition is safely armed only when it reaches its intended target or specified conditions. When this device malfunctions, it may fail to keep the weapon safe, resulting in an unintended detonation before the weapon is supposed to be activated. This can pose a significant risk not only to the intended target but also to the personnel handling the weapon.

In contrast, while preventing the weapon from functioning or reducing explosive yield may seem plausible consequences, the primary concern with a malfunctioning Safe and Arming Device is the potential for it to cause an explosion that occurs too early in the sequence of events for the weapon's intended use. Similarly, stabilizing the projectile in flight is not related to the operation of the Safe and Arming Device; the device's role is focused on safety and arming, not on projectile stabilization.
