The self-destruct fuse timing is defined as?

• A. Fuse timer detonates warhead approximately 17 seconds if missile has not hit target
• B. Fuse timer detonates warhead on launch
• C. Fuse timer delays detonation until impact
• D. Fuse timer does not detonate the warhead

Answer: (A)

Self-destruct fuse timing is a safety feature that triggers detonation if the missile hasn’t hit a target within a defined window. In this system, the timer is set to about 17 seconds after launch, so if the missile misses or cannot complete the engagement, the warhead detonates anyway to prevent a live, hazardous item from remaining in flight. It isn’t meant to detonate at launch, nor to wait until impact, nor to simply not detonate. The 17-second setting ensures a predictable, safe termination of the warhead if the target isn’t reached.
