Which component provides power and activates the battery to the missile rounds?

• A. Azimuth Determination Unit
• B. MUJB
• C. Power Distribution Unit
• D. Missile Interface Module

Answer: (D)

Powering the missiles and activating their onboard battery is handled by the component that sits at the interface between the launcher and the missile rounds. The Missile Interface Module provides the electrical connection to each missile, delivering the power to the missile’s internal battery and sending the activation/arming signals needed to bring the rounds to a ready state. It also coordinates with safety interlocks and the proper sequencing required before launch.

The other components have different roles: the Azimuth Determination Unit handles aiming data, the MUJB is involved in launcher electrical/bus connections, and the Power Distribution Unit routes power to subsystems rather than directly enabling the missile’s battery and readiness.
