What is the device used to initiate bomb detonation at a predetermined time and under desired circumstances?

• A. A fuse used to ignite the propellant for propulsion.
• B. A safety pin used to carry the fuse.
• C. Device used to initiate bomb detonation at a predetermined time and under desired circumstances.
• D. A device to detonate upon impact only.

Answer: (C)

The key idea is how ordnance is armed to detonate at the right moment. The device that starts the detonation of the main explosive charge under a set time or under chosen conditions is the fuze (the fuzing device). It is designed to arm after safing devices are removed and then initiate the explosion when the timer expires or when a sensing condition is met, ensuring detonation occurs at the intended moment. The other options describe different functions: a fuse that ignites propulsion is for propelling motors, not detonating the main charge; a safety pin is part of the safing process but does not trigger detonation; and an impact-only detonator would detonate on contact, not at a pre-set time or under specified conditions.
