Aviation Ordnanceman (AO) Strand Practice Test

In fuzed ordnance, what does 'armed' indicate regarding the fuze?

The fuze is ready to detonate under the specified condition The fuze is disconnected The fuze is physically removed The fuze is watertight but inactive

Correct Answer:

The fuze is ready to detonate under the specified condition

Explanation:

Armed means the fuze has completed its safing/arming sequence and is primed to function. Once armed, the fuze will initiate the explosive train when its designated condition occurs—such as impact, proximity to a target, or a timed signal—depending on the fuze type. The arming process removes or activates the safety barriers so a valid trigger can cause detonation. If the fuze is disconnected, removed, or simply watertight but inactive, it is not armed and will not detonate under the designated conditions.
