Which component is responsible for power and battery activation to the missiles?

• A. Missile Interface Module
• B. Interceptor Guidance Unit
• C. Azimuth Determination Unit
• D. Launch Vehicle Controller

Answer: (A)

The main idea is that powering the missile and activating its onboard battery are handled at the interface between the launcher and the missile. The Missile Interface Module is the component that connects the missile to the launcher’s power system, ensuring proper voltage, safe power transfer, and timing for battery activation. When the launch sequence proceeds, this module enables the missile’s power path and triggers the battery activation so the missile’s electronics are powered in time for flight.

The other components have different roles. The Interceptor Guidance Unit provides the guidance and navigation data that directs the missile during boost and flight; it does not supply or manage the missile’s power. The Azimuth Determination Unit handles orientation and bearing information but not power activation. The Launch Vehicle Controller coordinates the overall launch sequence, safety interlocks, and communications, but it does not directly energize the missile’s power or activate its battery.
