Mobility Deff describes which concept?

• A. The speed of AMD interceptors
• B. The number of launchers in the formation
• C. The altitude at which defenses operate
• D. Capability to move from place to place while retaining AMD capability

Answer: (D)

Mobility describes the ability to move from place to place while retaining AMD capability. This matters because moving the defense assets — launchers, radars, and command posts — keeps the system survivable and adaptable in a contested environment. It enables persistence in protection by denying the enemy a fixed target, while still allowing continuous detection and engagement of threats as the system repositions.

The other ideas—how fast interceptors can fly, how many launchers are available, or the altitude at which defenses operate—cover performance, capacity, and airspace parameters, not the core idea of moving and staying effective.
