The Stinger Missile will self-destruct after:

The Stinger Missile will self-destruct after:

• A. 15 seconds
• B. 20 seconds
• C. 25 seconds
• D. 17 seconds +/-2 seconds

Answer: (D)

Timing the self-destruct mechanism is the idea being tested. The Stinger is designed to trigger self-destruction at a nominal 17 seconds after launch, with a tolerance of plus or minus 2 seconds. That means the actual self-destruct could occur anywhere from about 15 to 19 seconds after launch. This safety feature keeps the missile from remaining active too long in the air and reduces risk if no target is engaged. The correct descriptor is the one that states 17 seconds with a ±2-second tolerance, because it conveys both the intended time and the allowable variation. Fixed times like 15, 20, or 25 seconds don’t reflect the specified tolerance and aren’t the precise description of the timing.
