What is the purpose of the AN/GYQ-79 CMBRE?

The AN/GYQ-79 CMBRE (Common Missile Bombing Range Equipment) serves the purpose of imitating built-in tests and assessing the systems status of various weapon systems. This capability is vital for evaluating the operational readiness and functionality of military equipment, ensuring that the systems are working as intended before they are deployed in training or combat scenarios. By conducting these assessments, military personnel can identify any potential issues with the systems, allowing for timely maintenance and upgrades, thereby enhancing overall operational efficiency. The focus on built-in tests emphasizes the importance of maintaining high standards in military readiness and operational capability.

The other options, while related to military operations, are not the primary purpose of the AN/GYQ-79 CMBRE. Monitoring flight patterns and providing GPS navigation are functions that relate more to tracking and guidance systems rather than assessing system readiness. Similarly, controlling explosive detonations represents a different aspect of military operations that is not connected to the primary functions of the AN/GYQ-79.
