AMMO CDC Module 6 Practice Test

The effective range is the distance at which the AGM-88 can reliably detect an emitting radar, acquire it, and guide to a high-probability intercept under typical conditions. The AGM-88 HARM homes in on radar emissions during the terminal phase, so the distance from which it can consistently engage a target is limited by the missile’s propulsion, seeker performance, and the need to maintain a usable radar lock. In common training and operational planning, this practical stand-off is about 30 miles. It reflects a balance between enough energy to reach the emitter and the reliability of triggering the seeker on the radar signal. While the missile can travel farther in some scenarios, 30 miles is the range used to ensure a dependable engagement. The other distances are either beyond typical reliable engagement under normal conditions or too short to allow an effective anti-radiation attack.
