What is the function of the Safe & Arm device on the THAAD launcher?

The Safe & Arm device is all about safety interlocks that control when the interceptor can arm. It secures the interceptor in the launcher and ensures arming only happens under authorized conditions and safe states. This prevents accidental or unauthorized arming during handling, transport, or maintenance and guarantees that arming occurs only when verified as safe. That makes the description of securing the interceptor and enabling arming only under authorized conditions and safe states the best fit. The other ideas misrepresent the function: one narrows it to monitoring something like battery voltage, which is too limited; another would imply continuous operation regardless of state, which is unsafe; and another suggests automatic loading without authorization, which also conflicts with safety.
