Final answer:
The arming delay distance for the M505 fuze is the minimum distance the fuze must travel after being fired before it becomes active and capable of detonating the explosive payload.
Step-by-step explanation:
The arming delay distance for the M505 fuze is the minimum distance the fuze must travel after being fired before it becomes active and capable of detonating the explosive payload. The arming delay distance is designed to ensure that the fuze will not detonate prematurely, such as during the gun barrel's initial acceleration or upon firing. This distance allows for the projectile to stabilize and reach a safe distance from the gun before the fuze becomes operational.
