When engaging a virtual target, during the final seconds of missile flight, the missile is commanded to ______ and continues toward the selected target.

• A. Lock On
• B. Return to Base
• C. On-Board Home on Jam
• D. Self-Destruct

Answer: (C)

The main idea is that in a close-quarters, high-stress intercept, the missile switches to an autonomous, jam-robust guidance mode so it can finish the kill even if the target’s radar is being jammed or the lock is lost. On-Board Home on Jam means the missile uses its own onboard guidance to home in on the source of the jamming (which is near the target), allowing the missile to steer toward where the target is expected to be and complete the intercept. This is preferred in the final seconds because it reduces reliance on an active, possibly degraded, external seeker, ensuring the missile still reaches the target area. Returning to base or self-destruct would abort or sacrifice the intercept, and locking on requires continued track which may be compromised by jamming.
