Joint Fires Observer (JFO) Course Practice Test

Which statement is NOT true about fuze function methods?

Hydrostatic (Depth Charge) is a fuze function method. Impact / Delay is a fuze function method. Proximity is a fuze function method. Spin is a fuze function method.

Correct Answer:

Spin is a fuze function method.

Explanation:

Fuze function methods describe how a fuze decides to detonate. Hydrostatic (depth charge) uses water pressure to trigger at a specific depth. Impact/Delay activates on physical impact and then uses a short delay before detonation. Proximity uses a sensor to detonates when the warhead is near the target. Spin, on the other hand, is not a fuze function method; it pertains to the projectile’s rotation and stabilization, not to the fuze’s triggering mechanism. So, saying spin is a fuze function method is not true, which is why that statement is the correct choice.
